Notes:
When you create a new project, you can use file structures, form sets and
macros from a similar project. This is a good approach because it means that
you can re-use existing work and promote consistency between projects. In
fact, many MICROMINE users create a template project and save any re-usable
file structures, macros and form sets within it. This approach is demonstrated
in the following exercise.
You can also rename, move, delete and attach projects. Renaming simply
changes the project name. Moving a project manages the entire process of
moving all the project files from one location to another.
Because project data files are stored in different folders you can use the same
file names in each project. For example, the projects “Demo” and “Training”
can both have files named collar.dat , survey.dat and assay dat ..
By default, MICROMINE will load the last project you were using.
Creating a New Project
Because the data for this training course have already been prepared, you’ll
attach to a project where the data are stored. However, you still need to know
how to create a new project. Since it’s good practice to learn how to create and
use a template project, this is a good opportunity to do so.
Exercise 1.1: Create a new project
To create a new project:
1. Start MICROMINE by clicking on the icon on your desktop, or select the
application name from the Start menu.
2. Select File | Project | New from the main menu.
3. Fill-in the dialog box as shown below. When you define the Project path,
use the browse […] button to navigate to the H: MmData folder; once
you’ve done this you can type the remaining Templates text yourself.

![MICROMINE Training v9.2 Module 01 – Micromine Basics (Rev 05)
Notes:
4. Click OK to create the project. The program will open in the new project.
Under normal circumstances you’d now begin creating files and loading data
into the project. When you next create a project you can select Use existing
project as template and then enter its name. You can then nominate which
items you want to re-use from the template project by selecting from the
options shown in the group at the bottom of the dialog box.
Attaching an Existing Project
Attaching a project is a convenient way of working with existing projects and
external data such as old projects and data created using other applications.
Once you’ve attached a project, you can select it as though you had created it.
This procedure assumes you’ve accepted the default settings when you
installed from the Training CD.
If you changed the location of the installed data set, you’ll need to substitute
the project folder name and path you used in the instructions that follow.
Exercise 1.2: Attach an existing project
To attach an existing project:
1. Select File | Projects | Attach from the main menu.
2. Enter the Project name. This is the name of the folder containing the
project data. In this case, enter: Training
3. Click the Browse […] button next to the Project path response and
navigate to the folder H:MmDataT aining . Click OK on the Browse
dialog.

Exercise 2.3: Opening Graphic Display Windows. Notes:
1. Move your mouse button over the Display Pane tab, and pin it to the
display as described in Excersise 2.2.
2. Click on the Vizex Button on the Main Toolbar, and observe the new
icon appearing in the Display Pane.
3. Click on the 3D Viewer Button on the Main Toolbar, and observe the
new 3D Viewer icon appearing in the Display Pane.
4.
When you have data opened in any of these graphic display windows, the
objects loaded will be displayed as icons and titles under each object in the
display pane.
5. Select Window | Tile Horizontally from the main menu and observe
each window is now displayed on your screen.
6. Close one of the Vizex windows by clicking on the cross [X] in the top
right hand corner of the window. Repeat this for the 3D Viewer
window so that only one Vizex window remains.
7. Maximise the Remaining Vizex Window to the full screen using the
Maximise button on the top right hand corner of the window.
8. Click on the Pin Down icon on the Display Pane to hide the pane to
the left of the window.

![MICROMINE Training v9.2 Module 01 – Micromine Basics (Rev 05)
Notes:
3. Don’t select Use template?
4. Click OK and the New file window will appear.
In this window you create the file structure. To do this you must define:
• The names of the fields.
• The type (Character or Numeric) of each field.
• The width of each field.
• In the case of numeric fields, the number of decimal places.
Type the following values in the table:
Press the Tab key to move right from field to field and Shift+Tab to move to
the left. You can also use the arrow keys to move up and down, or just click on
a cell with the mouse. Press Enter to create a new row.
1. Once you’ve entered these values, click Close on the menu in the New
window.
2. Click Yes to confirm you want to create the file.
3. The new file will open into a File Editor window. You could start entering
values immediately but since it’s intended to be a template file you’d
generally leave it empty.
4. Close the File Editor window, either by clicking the [X] at the top right of
the window, or by clicking the Close toolbar button.
Field names can have up to 10 characters. Field names that
include spaces are not recommended. Best practice, unless
there’s an overriding company standard, is to keep field names
simple. For example, use Sample rather than Sample No.,
Sample_No or Sample #.
Similarly you can only enter a C or an N as a field type. Length can
be up to 255 characters but should be kept as short as possible
without compromising the data. The decimal point is counted as
one character. For example, N 10 2 would allow only 7 digitsto the
left of the decimal point. There’s nothing to be gained by
specifying more decimals than are needed.

![MICROMINE Training v9.2 Module 01 – Micromine Basics (Rev 05)
also allows you to recall a previously saved form set, and import or export form
sets for sharing with other users.
Notes:
Some dialogs have buttons that open other dialogs. In MICROMINE, the
“parent” dialog is called a dialog fo m , and the “child” dialogs are known as
dialog boxes . All dialog boxes that belong to a dialog form are automatically
saved together with that particular dialog form.
r
Each MICROMINE function maintains its own independent list of form sets, so
there’s no risk of duplication. For example, more than one function could have
a form set Number 1, with the title “Testing”.
Even if you forget to save a dialog as a form set, every MICROMINE dialog is
automatically saved to a ‘default’ form set. Simply re-opening a particular dialog
will automatically recall the default set, so your previous settings are always
available, even after restarting the computer. As soon as you change a value,
however, the previous value will be lost.
Forms are a very useful facility. They promote consistency and save
you from re-entering values.
Exercise 4.1: Explore dialogs and form sets
In this exercise, we’ll use the Simple Display function to display some
geochemical sample locations and save the display parameters as a form set.
1. From the main menu, select Display | Simple.
2. Before choosing any data, click the Display Limits… button and confirm
that the Display Limits dialog is empty. Close the Display Limits dialog.
3. Double-click the File response and choose NVG_GCM from the list.
4. Once you’ve chosen the file, re-click the Display Limits… button and
note that the coordinate fields and their minima and maxima have been
automatically set. Close the Display Limits dialog.
5. Double-click the small blank square next to the Symbol prompt and
choose a plus [+] symbol.
6. Click the first OK button on the toolbar to run the function and test your
settings.
Most functions in MICROMINE use a Run button on the dialogue
form to run functions, however, for graphical display functions such
as Display | Simple, you run MICROMINE functions by clicking the
first OK button on the toolbar.
7. Close the display window using File | Close, or the cross in the top right
corner of the window to return to the dialog.
Assuming you’re happy with the settings, you can now save them as a form
set.
1. Click either the Forms menu or Forms toolbar button.
2. On the Forms dialog, click Save As.

![MICROMINE Training v9.2 Module 01 – Micromine Basics (Rev 05)
3. When the Save Current Values dialog appears, type in the Title
Geochem Display and click OK . Both dialogs will disappear.
Notes:
4. Click the Forms menu or toolbar button a second time, and note that your
newly saved form set appears in the list of saved form sets.
If you wanted to re-use those settings, you’d simply click the appropriate form
set to select it, and then click Open to load the settings.
Merging Assay Data
We added fields to the data file in Exercise 3.3 to prepare that file for the
merging process. The NVG_GCM file contains a sample number, co-ordinates
describing where the sample was taken, and some other information. A file
called MMI_ASSAY_RESULTS.TXT (for convenience in the Import folder in the
current project) contains the assay results and sample numbers that
correspond to the coordinates.
In this task we’ll merge the soil sample assays (MMI_ASSAY_RESULTS.TXT )
into the file containing the locations where the samples were collected
(NVG_GCM.DAT ).
To successfully merge the records in two files, there must be a field with the
same values in both the target and source files. This is known as a key field . If
the key field in each file contains duplicate values, you must use two or more
fields in each file to differentiate each record.
The Merge function processes the target file record by record. It finds the key
field in each record and reads the value it contains. It then looks for the same
value in the key field in the source file. When it finds an equivalent value, it
takes the data from the fields you’ve nominated, and writes it to the
corresponding fields in the target file.
It’s important that you know the column order in which the sample
data has been returned if the assay file does not contain a header
row. In this case, the field order is: Au1, Au2, Au3, Ag, C u, Pb, Zn,
Ba, Mo, Sb, As, Hg and Tl.
Exercise 4.2: Merge assay data into a sample locality file
In this exercise the sample identifiers are unique. This means you can use the
fields containing sample identifiers in each file as the key field in the merge. In
cases where there are duplicates in the key field in the target file you must use
multiple fields to form the key.
Do the following:
1. Select File | Merge | Text from the main menu (There’s also a Merge
function under the Edit | Tools menu of the File Editor but it doesn’t have
as many features as this one.)
2. Click the browse […] button beside the Text file path response and
navigate to the file MMI_ASSAY_RESULTS.TXT in the Import folder (this
file can be external to the project and is only here for convenience).
3. Double-click in the Target File response and select NVG_GCM from the
window that appears.

![MICROMINE Training v9.2 Module 01 – Micromine Basics (Rev 05)
8. Enter Unmerged in the Unmerged file response, Duplicate in the
Duplicate file response, and Merge_s ats in the Report file response.
These files will record the results of the Merge process.
Notes:
t
Running the merge
9. The final stage of the process is to run the merge. Do this by clicking the
Run button on the dialog box.
When the process is complete, a report will appear describing the results of the
process, which is reproduced in the Merge_stats file. Right-click the Unmerged
and Duplicate files to check their contents. The Unmerged report will list the
records in the source file that were not merged. The Duplicate report will list
the records with duplicate keys.
A useful check on any function that processes files is to right-click
the output file and choose View from the pop-up menu. Any
problems will become apparent and you can re-run the function
after making the necessary corrections.
Importing Text Files
A popular format for text data is CSV (comma separated values). Most
applications that can store and process tabular data can export in CSV format.
For example, field data recorded in a geologist’s notebook is often transcribed
from the notebook to a spreadsheet program such as MS EXCEL™ or Lotus™
before it’s imported into a MICROMINE project. CSV is generally used in these
cases.
If you use Field Marshal to collect field data, you can import or
merge files in native MM format. Field Marshal and the File Editor
contain many data entry and processing functions created
specifically for earth science data. It’s cheaper and easier to buy
Field Marshal or the File Editor than to try and write macros for MS
EXCELor Lotus.
Outlines are often used to record tenement boundaries. The tenement
boundary data can be obtained from your local mines department. Generally
this will be in the form of a series of distance, bearing pairs from a datum
point.
Exercise 4.3: Import a text file
In this exercise you’ll create a file and import the (distance, bearing) pairs that
were entered in an EXCEL spreadsheet and saved in CSV format. This exercise
will also illustrate another MICROMINE productivity tool: You can create a new
file virtually anywhere within MICROMINE.
Choose the Text File
1. Select File | Import | Text from the main menu.
2. Click the browse […] button next to the Text file path response and
navigate to the Import folder (within your project). Select the file
MMI_Tenement_Data.csv .

![MICROMINE Training v9.2 Module 01 – Micromine Basics (Rev 05)
2. Click the browse […] button next to the Lab file path response and
select the MMI_ NVG.SIF file (from the Impo t folder).
Notes:
r
3. Back on the Merge Lab Data dialog, right-click the file name and view the
file. Take particular note of the format (column or comma delimited?) and
the particular codes found within the file. Close the text viewer window
once you’re done.
4. Select Column Delimited .
5. Set the Method to Use sample field .
6. Because the sample numbers are in the first column, enter 1 in Start
column.
7. Select Character match .
8. In the Assayed Element Names group, position the cursor in the Row
response and right-click. Highlight the first column of element names in the
header as shown in the preceding illustration. Click Post Values.
9. In the Data group, do the same for the first row in the column of assay
values.
The function assumes that the columns in the source file all have the same
width.
10. Select Replace lab codes and click More…
11. Type NS into the first row of Lab Code, but leave Replace With blank.
This will blank out all occurrences of the string ‘NS’ from the MICROMINE
file.

![MICROMINE Training v9.2 Module 01 – Micromine Basics (Rev 05)
The File Editor has a Tools menu available under the Edit menu that contains
a collection of basic functions for importing, exporting and merging data;
sorting and validating files; and performing field-based calculations. Many of
these tools also have toolbar buttons.
Notes:
MICROMINE files are presented on-screen in a familiar grid layout. You can
navigate up and down through the file by using the keyboard up and down
arrow keys, as well as Pg Up and Pg Dn to go one page at a time. Of course,
you can scroll using the mouse, too. To move from one field to the next, press
Tab or Shift+Tab, or click into the desired field with the mouse. To create a
new record, simply press Enter at the end of the file.
The File Editor supports standard Windows shortcuts for editing text, for
example:
• Ctrl+C (Copy)
• Ctrl+X (Cut)
• Ctrl+V (Paste)
Using these shortcuts, you can easily transfer blocks of data between
MICROMINE and, say, MS Excel, in either direction. However, the File Editor
also provides many other unique shortcuts that are designed to automate
repetitive geological data entry tasks. You can access these shortcuts by
opening the Records menu. Some of these are summarised in Table 1 below:

![MICROMINE Training v9.2 Module 01 – Micromine Basics (Rev 05)
You can choose to ignore unsampled intervals for the interval
length check by selecting a grade field. Any intervals with a blank
for the grade field will be ignored for the validation check.
Notes:
4. Click OK . A series of status messages will appear as Validate processes the
drillhole files. If an error is detected, an appropriate message will be
displayed and the error will be written to the Report file.
5. Right-click the Report file and select View from the popup menu. This file
contains a record of all errors encountered during the validation process.
In this exercise, Validate detected some downhole survey errors, caused by
consecutive surveys deviating by more than 5°, and some errors for sample
intervals greater than 5m. These downhole survey errors could in fact consist
of valid data, so it’s entirely up to you to determine whether or not corrections
are required. If you were to re-run the validation using the NVG_LITH interval
file, you’d discover some inconsistent data in the interval (lithology) file. These
interval errors will require attention before the data can be used. However, the
training dataset already contains a validated file (NVG_LITH_NO_ERR ), so the
corrections won’t be necessary.
You’ve probably noticed that MICROMINE knew the names of the
fields in the drillhole files. You can set the field names that
MICROMINE allocates to dialog prompts by selecting Options |
Forms from the main menu. Here you can enter the names you use
for the fields at your site.
However, it’s still good practice to click each of the Fields…
buttons and check that the fields have been correctly allocated!
Using Lookup Tables
So far we’ve looked at validating pre-existing data, but it would be far better to
ensure those data were correct from the moment they were created. Using
MICROMINE’s Lookup Tables, you can establish a data entry environment
where this is possible.
Lookup tables serve two main purposes. Firstly, they act as a data entry tool,
minimising the amount of typing required. Instead of having to type a
particular code, for example, you can simply choose it from a list. When used in
conjunction with the other data entry shortcuts that we’ve already explored,
lookup tables make it possible to enter large quantities of data with few
keystrokes. This system works particularly well with pen-based devices such as
palmtops or PDA’s, which may not have a keyboard.
Secondly, and perhaps more importantly, lookup tables act as a data validation
tool. Keystrokes are validated as they occur, which ensures that your data are
correct from the start. There are numerous settings that control the way lookup
tables perform this validation task.
Lookup tables can be attached to any field in a MICROMINE file. Once
attached, they appear as an ellipsis […] button in each cell of that field.
Lookup tables remain active until they are detached.

![MICROMINE Training v9.2 Module 01 – Micromine Basics (Rev 05)
Compiling the Binary File Notes:
The MICROMINE file version of the lookup table is what you’ll edit and maintain
as administrator of this project. However, it’s not the file that the geologists in
the field will use. You must compile this file into a binary LBN file before it can
be attached to an interval file.
To compile the lookup table:
1. With the file open in the editor, select File | Compile from the menu. The
Lookup Table Properties dialog will appear.
2. Set the Enable validation and Case sensitive options, but leave the
remaining options blank.
3. Click Compile to create the binary LBN file. A message will appear
indicating successful creation of this file.
4. Close the File Editor window.
Attaching the Lookup Table to a Field in the Data File
The final stage in this process is to attach the lookup table to the appropriate
field of the NVG_LITH file. Once this is done, we can start using it.
1. From the main menu, select File | Open and open the NVG_LITH file.
2. Click the LITH field to select it. It doesn’t matter if you click the field
heading or just a cell in that field.
3. From the File Editor menu, select Format | Lookup Tables | Attach.
4. Choose LITH_LOOKUP from the list and click Open. MICROMINE will add
the ellipsis buttons to the LITH field displayed in the File Editor.
If desired, you could attach a lookup table to every field in a file.
You can also attach the same lookup table to more than one field.
For example, your file could have C olour1 and Colour2 fields.
Simply attac h your Colour lookup table to both!
5. Click one of the ellipsis […] buttons to open the lookup table. Your screen
should resemble the following diagram. From here, you can simply click
the desired code to select it.

Notes:
Starting Vizex
Vizex will open by default whenever you start MICROMINE. If Vizex is not
open, it can be opened with any of the following methods;
• Click the Vizex toolbar button;
• Load any object or saved view from the Form Sets Pane; or
• Load any object or saved view by selecting any option from the
Display | Vizex menu
Exercise 1.1: Load a previously saved view
In this exercise you’ll start Vizex and re-display a previously saved view.
1. Ensure Vizex is open. If Vizex is not open, open it by clicking on the Vizex
Toolbar button.
2. Once the Vizex environment is open, open the Saved Views node by
single-clicking the small plus [+] icon to its left. This node is located at the
top left of your screen, immediately under the menu and toolbar.

![MICROMINE Training v9.2 Module 02 – Displaying and Manipulating Data (Rev 05)
Notes:
3. Double-click the Lesson One object to open it.
4. Vizex will load a number of different display objects into the window and
then change the window extents to match the saved view.
The User Interface
The Vizex environment consists of three primary areas: the Graphic Display ,
which occupies the bulk of the screen; and the Form Sets and Display/Objec
Manager window panes, which by default dock to the left hand side of the
screen. If desired, you can dock the Form Sets and Display panes to the left,
right, top or bottom of the Graphic Display, or move them to an undocked
position floating over the graphic display. There is an auto hide icon on the
Form Sets and Object Manager window which can be used to maximise the
Graphic Display area and hide these windows when they are not in use.
t
You can toggle the panes on and off by clicking the Form Sets and Object
Manager icons on the main toolbar. Alternatively, you can open these panes
by selecting View | Object Manager or View | Form Sets from the menu.
To close the panes, click the Close button at the top right-hand corner of each
pane.
The View toolbar at the top of the screen provides a variety of tools for
selecting and manipulating data, and manipulating the view. Depending on the
tools you’ve selected, Vizex may also display additional toolbars.
Form Sets Pane
You use the Form Sets pane to select the Form Set Objects you want to include
in the Graphic Display. Before you define a Form Set Object as a Display
Object , you can modify form set properties to control the way data will appear
in the display.
To create a Form Set Object, select an option from the Display | Vizex menu.
Alternatively, you can double-click an object type under the Vizex Folder to
create a new Form Set Object.
If there are no objects displayed under the Vizex Folder in the Form Sets Pane,
simply click on the plus [+] icon to it’s left to expand the options.

Notes:
Now that the Points display is completed, it makes sense to save it as a form
set for later re-use. To do this, follow these steps:
5. Click the Forms button (on the Load Points dialog) to display the Forms
dialog, and then click Save As.
6. Type in the title Surface geochem and click OK to return to the Load Points
dialog. Observe how the title now appears at the top of the dialog.
7. Click OK on the Load Points dialog to update the display, which should
now resemble the following diagram.
If you inspect the Display pane, you’ll see that the name of the display object
has changed from NVG_GCM.DAT to Surface geochem . Additionally, if you
check the Form Sets pane, you’ll notice that the Sur ace geochem object also
appears as an item under the Points form set node.
f
At any time, if you click the plus [+] icon next to a form set node
you can expand the tree to display the saved form sets listed
underneath it. However, your settings will only appear if you’ve
saved them asa form set.
Loading a Tenement Outline
MICROMINE uses outlines to represent closed shapes, such as geological units,
ore grade outlines, or tenement boundaries. Outline files support fill patterns
and colours for presentation, and can be labelled with a variety of attributes.
In this exercise, you’ll load a simple outline file containing a tenement
boundary.

Exercise 2.5: Display an aerial photograph
To display an image:
1. On the Form Sets tab, double-click the Image object type to display the
Load Image dialog. Alternatively, you can also select Load | Image
from the menu. Ignore the values already in the Image dialog; they’re
simply left over from Lesson 1.
2. Click the browse […] button next to the File response and double-click
the Import folder. Select the MMI_IMAGE.ECW file. MICROMINE will
automatically search for and load the georeferencing header information.
3. Set the Image intensity to 400 . This will stop the image overpowering
the other information in the display.
4. Set the Orientation to PLAN .
5. Set the Section to 1600 . This will set the image to the approximate RL of
the surface topography in that area.
6. Click Forms followed by Save As and save the settings as a form set
called Air photo . Click OK on the Load Image dialog to return to Vizex.
7. You’ll see that the image obscures all of the other data in the display. To
change the display order, drag the Air photo object (in the Display pane)
to the bottom of the list. When you release it, the display will refresh with
the photo beneath the other objects.
MICROMINE supports most common image and georeferencing
formats. If you have an image in an unsupported format, use a
graphics conversion program to convert the file into a compatible
format. In addition, if you want to use a large image, it’s best to
convert your image into the highly compressed ER Mapper ECW
format.

Exercise 2.7: Add the grid to the display Notes:
It makes sense to use a modified version of the colour set you created for the
Points display.
1. Double-click the Grid File object type on the Form Sets pane.
2. Double click the Grid file response and choose NVG_AU1_CONTOUR .
3. Set the Orientation to PLAN .
4. Double-click in colour Set number, and select Grid geochem Au1 from
the list. Click Select to open the form set.
The grid file actually coversthe entire area, but by “nulling” out the
low values, we’ve produced a display grid that only highlights the
anomalies.
5. Click Forms then Save As and save the settings as a form set called MMI
Soils Geochem Au1 . Click OK on the Grid File dialog to return to Vizex.
Completing the Picture
Now that you’ve defined the final item for your display, you can reload your
previously saved form sets at any time you wish to use them. If you inspect the
Form Sets pane, you’ll notice that the Grid File, Outlines, Points and
Image object types all have a new plus [+] icon next to them.
To remove the existing display items:
6. Select Edit | Remove All from the main menu.
To reconstruct your display:
7. Click the plus [+] icons next to the Outlines, Points, Image and Grid
object types to display the form set objects that you previously created.
8. Double-click on each of those form sets to load them into Vizex and rapidly
re-construct the display.
9. If you need to change the display order, drag the objects in the Display
pane to change their order to your satisfaction. Your display should look
something like the following picture.

(looking north) to a long section (looking west). Vizex remembers your clipping
settings and applies them where appropriate.
Notes:
In any Orthogonal Section, the Elevation/Section value is displayed in an
editable input box on the view toolbar next to the standard viewing buttons. A
section value can be entered in this box, and when you wish to return to this
section or elevation, it can be re-selected from the dropdown menu.
Exercise 3.3: Display data in cross section
In this lesson, you’ll set up a standard looking north cross section, followed by
a transform section.
First, let’s set up the section display:
1. Click the plus [+] icon next to the Wireframes object (in the Form Sets
pane) to display the list of previously saved form sets, and double click the
DTM 2D slice mode object to open it.
2. Click the Display Limits toolbar button.
3. Change the View Type to Looking North .
4. Set the Section Northing to 15900 .
5. Activate Clip to window? and set both Away and Towards to 15 .
6. Click OK to make the changes. Vizex displays the section.
7. Click the Next Section and Previous Section buttons to browse through
the data.
The status bar displays the current 3D cursor coordinate (which
incorporates the section number) at the lower right corner of the
screen.
Now, let’s set up a transform section:
1. Click the Plan button to return to a standard plan view.
2. Right-click in the Graphic Display and choose View All from the pop-up
menu.
3. Click the Section toolbar button and drag an oblique section at an angle
to the drillholes. Note how Vizex displays the section extents as you drag
the mouse. When you release the mouse, Vizex displays the transform
section.

![MICROMINE Training v9.2 Module 02 – Displaying and Manipulating Data (Rev 05)
Exercise 4.1: Activate the Graphic Editor Notes:
In this exercise, you’ll load several objects that you’d use for a sectional
drillhole interpretation and turn on the graphic editor.
1. Open the Saved Views node in the Form Sets pane by clicking the small
plus [+] icon next to it.
2. Double-click the Lesson Four object to load it. Vizex will load four display
objects, but only one, an outline file containing a series of rock unit
interpretations, will be turned on.
3. Click on the Sectional geology interp object in the Display pane to select
it. Vizex will do two things: It will place a selection rectangle around the
outlines in the graphic display and it will enable the Graphic Editor
toolbar button.
4. Click the Graphic Editor button to activate the Graphic Editor. A new
toolbar will appear.
Elements of the Graphic Editor
The Graphic Editor’s primary interface is the Graphic Editor Toolbar:
Using this toolbar, you can access these main editing functions, which are listed
in the order that they appear in the toolbar:
• New String: Begin digitising a new string.
• Snap: Toggle snapping on and off or select snap to point, snap to line, or
snap to grid.
• Insert Points: Toggle insert on and off.
• Between tool: Draw a string by inserting points between two selected
points.
• Follow tool: Allows you to create new strings following an existing string,
or to create copies of a string, or section of a string.
• Insert Intersection: Insert a point at the intersection of two existing
strings.
• Extend String: To append points to one end of a string.
• Close String: To close the selected string – the start and end point of the
string will be connected by a new segment.
• Expand String: Expand a string based on the Expansion distance defined in
the Options dialog.
• Create DTM: Generate a DTM based on the current string.
• Drape on Wireframe: Drape a string onto a wireframe.

![MICROMINE Training v9.2 Module 02 – Displaying and Manipulating Data (Rev 05)
• The Prefix is any 3 to 4 characters indicating what type of interpretation
you’re doing – for example ORE for ore grade envelopes, GEOL for rock
unit boundaries, and so on.
Notes:
• The Number is any ordinal number that indicates the progression of
sections – you could just start at 1 and count upward, or you could
number each file using the section’s northing or easting value.
Within an outline file, you should name each outline according to the feature
you’re digitising. If you’re digitising Number Four Lode, then give it a name like
NO4. As you progress from one section (and therefore outline file) to the next,
if it’s the same feature, keep giving it the same name.
Where there’s more than one outline in an outline file, each outline must be
uniquely named. So, if a particular feature bifurcates or splays, use a suffix
(e.g. _H for hangingwall) to keep the names unique.

Exercise 5.1: Set up a new outline file
Before we create the new file and begin our ore grade envelope interpretation,
let’s prepare the display:
1. Open the Saved Views node in the Form Sets pane by clicking the small
plus [+] icon next to it.
2. Double-click the Lesson Five object to load it.
3. Open the Drillhole Trace node in the Form Sets pane and double click
your Simple assay display form set to load it.

![MICROMINE Training v9.2 Module 03 – The 3D Viewer (Rev 03)
2. Under 3D viewer, double click on the Points icon. If there is nothing
listed under 3D viewer in the Form Sets tab, click on the [+] sign next to
the 3D Viewer Folder to expand the options.
Notes:
3. On the Load Points dialog, double-click the File response and choose
NVG_GCM from the file list. Leave the remaining responses set to their
default values.
4. Click on the Forms button and save the form as Geochem Points.
5. Click OK to load the points.
Note that opening an object in 3D Viewer does not close the Vizex
window. If at any time you wish to return to your Vizex display, you
can select the Vizex Window from the Window menu, or click on
the Vizexdisplay on the Display Pane
Now you’re ready to explore the 3D Viewer environment.
Decoration
The controls that appear around the lower edge and sides of the 3D Viewer are
known as decoration . These controls provide a means of manipulating the
contents of the view. Decoration is turned on by default when you enter 3D
Viewer. The Default can be switched off by unticking Show Decoration on
the 3D Environment Setup found under Options | 3D Environment. The
decoration can also be turned off and on using View | 3D | Decoration.
• The two thumbwheels at the bottom left corner of the window rotate the
data about the X- and Y-axes of the screen . They work as if they were
connected to an axle running through the centre of your screen.
• The thumbwheel at the bottom right corner of the window moves your
viewpoint in and out of the data. It’s called the Dolly wheel, which is a
name inherited from the motion picture industry. Using this control is
equivalent to walking toward or away from a scene whilst looking through
your camera’s viewfinder.
• The slider to the left of the Dolly wheel is the zoom control. This control is
only enabled if the view is in perspective mode, and is equivalent to
changing the zoom on your camera while looking through the viewfinder.
The cluster of buttons at the right of the display contains the basic tools that
you’ll use to manipulate the view and select data. The buttons are reproduced
and explained below:

display, remove them, or change their properties. You can also change the
direction of the illumination and the background colour of the scene.
• Use the View menu to select, save or restore a viewpoint. You can
position the camera in plan view or according to a cardinal point, and then
save this setting in a Form. You can also select (or clear) default viewing
features, rotation axes, decoration, drawing style and mode. Options for
changing the direction of the illumination, adding extra light sources and
changing the background colour of the scene are also available under the
View menu.
• Use the Wireframe menu to view and select from the wireframe types in
the current project, load wireframe sets and enter edit mode after loading
a wireframe object.
• Use the Plot menu to create a plot of your 3D data by selecting the 3D
Plot function.
• Use the Flight Path menu to generate, edit and save 3D fly-throughs of
your data.
The Form Sets Pane
You use the Form Sets pane to select the form set objects you want to include
in the 3D Display. Before you define a form set object as a 3D Object, you can
modify the form set properties to control the way the data will appear in the 3D
Display.
To create a Form Set Object in 3D Viewer, select an option from the Display |
3D Menu, or alternatively, double-click an object type under the 3D Folder to
create a new Form Set Object.
If there are no objects displayed under the Vizex Folder in the Form Sets pane,
simply click on the plus [+] icon to it’s left to expand the options.
The Object Manager
The Display Pane now replaces the Object manager in 3D Viewer in Previous
Versions of MICROMINE. Objects displayed in a 3D Window are displayed
under the 3D icon representing that 3D Window in the Display pane.

- 5. Micromine Training Introductionto Micromine Approach This course will be dominantly hands-on. Each new topic will commence with a brief introduction, followed by a practical exercise. A small training database will be used for all exercises. How to Use This Manual For further study While the primary purpose of this module is to introduce you to the key features of Micromine, optional tasks are included to expose you to more advanced features of the application. In addition to these optional tasks, in-house experts at Micromine have contributed their ideas on how to get the most from the application. You’ll find these ideas at the end of many lessons under the heading Good Practices. Using the online help with the training manual Where appropriate, references to topics in Micromine’s online help are also included. These references provide further information about the current task as well as topics that are related to the current task. They also give you an opportunity to become familiar with the online help system. Online help references will be displayed as italic in the following format: Keyword: Topic name For example: ODBC: Installing ODBC To look up a reference using the online help: 1. Select Help | Contents from the Micromine menu. 2. When the Help window appears, click the Index tab to select it. 3. Enter the keyword. In the above example, the keyword is ODBC . If there’s only one topic with that keyword, it’ll be displayed immediately. If the keyword is used in a number of topics, the titles of those topics will appear in a list. 4. Double-click a topic in the list to select it. Referring to entries in dialog boxes and files In many places you’ll need to make entries in dialog boxes or data files (tables). In this manual, the text or values you need to enter as part of the exercises will be illustrated in one of two ways: • A screen-shot of the relevant dialog form or dialog box with the correct entries. • A tabular display. The first column contains the name of the dialog prompt and the second column contains the text or value to be entered. Copyright © Micromine Pty Ltd 2004 iii

MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) Notes: Lesson 1 – Preparing the Project Data Duration: 45 minutes In MICROMINE, the project is the fundamental means of storing and organising your data. This lesson introduces you to projects and how you can use them. After this lesson you’ll be able to: • Create a project; • Attach to an existing project; • Delete a project; and • Delete a project without deleting the associated data. Working with Projects Projects Normally you’ll store all the data from an area in a project. This includes surface samples, drilling data, tenement outlines, aerial surveys, photography, and any other related information. In addition to information about an area, other information such as macros and form sets are also stored as part of a project. Put simply, a MICROMINE projec t representsa real-world project. To begin working with MICROMINE you must create a project. A project is simply a folder (or directory) where you store files containing related information. Once several projects have been created, you’re able to select a project you want to work with. When you select a project, all the files, macros and forms sets stored with that project are made available to you. Since you’re working in the project folder, there’s no need to enter a file path (i.e. C: projects tenement1 ...) when you create or open files. The only time you’ll “leave” the project is when you need to access external data. When you create a project, you enter a project name, a path, and a project title. The project name becomes a new folder on that path. A project may be located locally on the computer you’re using, or on a remote computer network. In either case, MICROMINE recommends that you save all your projects under a single parent folder. You must also set the units for a project to Metric or Imperial when you first create it. The default is Metric. Imperial is only used when rock densities are measured with a tonnage factor and plot scales like 20":1’ are required. Copyright © Micromine 2004 Page 1
- 14. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) Notes: When you create a new project, you can use file structures, form sets and macros from a similar project. This is a good approach because it means that you can re-use existing work and promote consistency between projects. In fact, many MICROMINE users create a template project and save any re-usable file structures, macros and form sets within it. This approach is demonstrated in the following exercise. You can also rename, move, delete and attach projects. Renaming simply changes the project name. Moving a project manages the entire process of moving all the project files from one location to another. Because project data files are stored in different folders you can use the same file names in each project. For example, the projects “Demo” and “Training” can both have files named collar.dat , survey.dat and assay dat .. By default, MICROMINE will load the last project you were using. Creating a New Project Because the data for this training course have already been prepared, you’ll attach to a project where the data are stored. However, you still need to know how to create a new project. Since it’s good practice to learn how to create and use a template project, this is a good opportunity to do so. Exercise 1.1: Create a new project To create a new project: 1. Start MICROMINE by clicking on the icon on your desktop, or select the application name from the Start menu. 2. Select File | Project | New from the main menu. 3. Fill-in the dialog box as shown below. When you define the Project path, use the browse […] button to navigate to the H: MmData folder; once you’ve done this you can type the remaining Templates text yourself. Copyright © Micromine 2004 Page 2
- 15. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) Notes: 4. Click OK to create the project. The program will open in the new project. Under normal circumstances you’d now begin creating files and loading data into the project. When you next create a project you can select Use existing project as template and then enter its name. You can then nominate which items you want to re-use from the template project by selecting from the options shown in the group at the bottom of the dialog box. Attaching an Existing Project Attaching a project is a convenient way of working with existing projects and external data such as old projects and data created using other applications. Once you’ve attached a project, you can select it as though you had created it. This procedure assumes you’ve accepted the default settings when you installed from the Training CD. If you changed the location of the installed data set, you’ll need to substitute the project folder name and path you used in the instructions that follow. Exercise 1.2: Attach an existing project To attach an existing project: 1. Select File | Projects | Attach from the main menu. 2. Enter the Project name. This is the name of the folder containing the project data. In this case, enter: Training 3. Click the Browse […] button next to the Project path response and navigate to the folder H:MmDataT aining . Click OK on the Browse dialog. r Copyright © Micromine 2004 Page 3
- 16. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) 4. Enter MICROMINE Training in the Project title. Notes: 5. Click OK to attach the project. You’re now attached to the Training project. Note how the MICROMINE window title bar (at the top of the screen) displays the new project’s name. When a project is created or attached, files in the folder H: Program Files Mm Template are copied to the new project (if they don’t already exist). If a template project is used the files in the Template project take precedence over those in the normal MICROMINE Template folder. Deleting a Project Deleting a project means removing the reference to the project (the folder where the project data is located) from a special MICROMINE file. There are two methods of deleting projects. The first method is to delete the link to the project folder. This is like deleting a shortcut from your Windows Desktop. The reference to the folder is removed but the folder and its contents remain untouched. The second method is to remove the link and delete the project folder and all the files within it. Generally, you’ll only want to remove the link to the project. Exercise 1.3: Delete an existing project To delete a project: 1. Select File | Project | Delete from the main menu. 2. Choose the Examples project from the list that appears. 3. Make sure Detach only is set (ticked). 4. Click OK . From now on, the Examples project won’t appear in the list when you select File | Project | Open from the main menu. To delete a project and all the files it contains, follow the same procedure but clear Detach only (remove the tick). Note that this is a deliberate action. You can’t ac cidentally delete the files in a project folder. Copyright © Micromine 2004 Page 4
- 17. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) Notes: Lesson One Summary These are the key points of this lesson: • The project is the fundamental structure for organising data in MICROMINE. • To start working with the program you must create a project. • Projects store data files, macros, and form sets. • You can set the project units to metric or imperial when you create it. • When you create a new project, you can use the file structures, form sets and macros from a similar project as a template. To create a new project: Select File | Project | New and enter the settings. To attach a project: Select File | Project | Attach, then Type in a new Name and Title, plus Browse to the project’s folder location (Path). To delete a project: Select File | Project | Delete and choose the project. Set the Detach only switch as appropriate. Good Practice Use existing projects as templates when you create a new project. Doing so will: • Encourage consistency in the way you store and process your data, and in the appearance of output. • Reduce set-up time because you won’t have to re-create data file structures, colour sets, macro files and form sets.

- 30. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) Notes: Lesson 3 – Working with Data Files Duration: 45 minutes Data files are the basic data container in MICROMINE. In this lesson you’ll learn about the different types of data files and how to create and work with them. After this lesson you’ll be able to: • Create a new file. • Create a file using an existing file as a template. • Modify a file’s structure. Working with Data Files Files in MICROMINE Most files you’ll use as input to functions in MICROMINE have a tabular structure. If you’re familiar with databases you’ll recognise this structure. An example of a typical MICROMINE data file is shown below. In each record there are Easting and Northing coordinates for a copper assay. The copper assay is associated with a sample number. There are several types of file used in MICROMINE. The main input files are Data , Survey and String . These files are differentiated by file extension. The data file has the extension DAT , the survey file SVY , and the string file STR . There are no other fundamental differences between these types of file. In fact a file with exactly the same structure could have any of these extensions. The main reason for having the different extensions is so you can group like files in a project. For example, geological data is often stored in DAT files; while Copyright © Micromine 2004 Page 18
- 31. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) contour strings and other string type data is stored in STR files; and survey information from total stations or theodolites is stored in SVY files. Notes: The data in most MICROMINE files is stored in ASCII format. This means you can easily read the data with simple text editors and viewers. While it’s possible to edit a MICROMINE file with a text editor, Micromine recommends that you don’t do so because the file format may become corrupted. There are other types of MICROMINE files, however MICROMINE itself handles the creation and management of these. You, as the user, must create the files needed for a project. To do this you give the new file a name and then define its structure. That is, the names and characteristics of the fields and the order in which they will be processed and displayed. There are two field types in files: Character and Numeric . In most cases it’s easy to decide which type you should apply to a field. Data that’s essentially numeric should be in fields with the Numeric type. Statistical functions will only operate on numeric fields and colour and hatch sets are defined differently for numeric and character fields. Note that you can still type non-numeric data into numeric fields, for example, NS (not sampled) in an assay field. Alpha and alphanumeric data is generally given the type Character. Some examples of common Character type fields are Hole Name, Sample Number, and Lithology Type. Date fields are stored as numeric in YYYYMMDD format. You should take care when importing dates from databases, as often you can’t control the date format. In general, MICROMINE processes data files to create output. You must tell a function (in MICROMINE) the name of a file and the fields it should use from that file. The function can then load data, record by record, from the file and perform its task. This is the fundamental operating paradigm of MICROMINE. The function takes values from the nominated file and processes them record by record Copyright © Micromine 2004 Page 19
- 32. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) Notes: The main file preparation and processing tool is the File Editor . The File Editor has many features and data processing tools that are useful to the earth scientist. One of MICROMINE’s strengths is that you can copy the contents of a file or change its structure at anytime. Such flexibility is very convenient. However, if you’re not using a central database it’s very easy to create copies of master files and get into a situation where a colleague enters new data into the copy. To avoid this, companies need to have conventions that clearly define file- naming procedures. For example, to make working copies of files easily rec ognisable, use a prefix like “#” or “!”. The length of the file name is no longer an issue. Similarly, with master files, you can include “master” in the name of the file. Before you begin the next lesson… Make sure you’ve loaded the data on the Training CD onto your PC or some location on your network. You’ll need this data throughout this training course. See Installing the data set for details. Creating a New Data File Because you’ll be using the data set supplied as part of this course you’ll only need to create a couple of new data files in later lessons. However, to reinforce the idea of the template project, this task will show you how to create a collar file that could be used as a template. Exercise 3.1: Create a new data file Before you begin, open the TEMPLATES project you created in the last lesson. A project like this is where you should store all template files. To do this: 1. Select File| Project | Open from the main menu. Alternatively, you can use the Open Project toolbar button. 2. Select TEMPLATES from the list that appears. 3. Click OK . To create the new collar file template: 1. Select File | New from the main menu. Alternatively, you can click the New toolbar button. 2. Enter the following values into the New File dialog box: Prompt Setting File COLLAR_TEMPLATE Type DATA Title Collar Template Copyright © Micromine 2004 Page 20
- 33. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) Notes: 3. Don’t select Use template? 4. Click OK and the New file window will appear. In this window you create the file structure. To do this you must define: • The names of the fields. • The type (Character or Numeric) of each field. • The width of each field. • In the case of numeric fields, the number of decimal places. Type the following values in the table: Press the Tab key to move right from field to field and Shift+Tab to move to the left. You can also use the arrow keys to move up and down, or just click on a cell with the mouse. Press Enter to create a new row. 1. Once you’ve entered these values, click Close on the menu in the New window. 2. Click Yes to confirm you want to create the file. 3. The new file will open into a File Editor window. You could start entering values immediately but since it’s intended to be a template file you’d generally leave it empty. 4. Close the File Editor window, either by clicking the [X] at the top right of the window, or by clicking the Close toolbar button. Field names can have up to 10 characters. Field names that include spaces are not recommended. Best practice, unless there’s an overriding company standard, is to keep field names simple. For example, use Sample rather than Sample No., Sample_No or Sample #. Similarly you can only enter a C or an N as a field type. Length can be up to 255 characters but should be kept as short as possible without compromising the data. The decimal point is counted as one character. For example, N 10 2 would allow only 7 digitsto the left of the decimal point. There’s nothing to be gained by specifying more decimals than are needed. Copyright © Micromine 2004 Page 21
- 34. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) Notes: Finally, return to the Training project: 1. Select File | Project | Open from the main menu. Alternatively, you can click the Open Project toolbar button. 2. Select TRAIN NG from the list that appears.I 3. Click OK to continue. Creating a New File Using a Template Once you have suitable files in the current project or have a template project or locations containing files with suitable structures, you can begin using them when you create new files. Exercise 3.2: Create a new file using a template To create a file using a template: 1. Select File | New from the main menu. Alternatively, you can click the New toolbar button. 2. Enter the following values into the New File dialog: Prompt Setting File TEST_COLLAR Type DATA Title From Template 3. Select Use template? 4. Click the Templates… button to display the Templates dialog. 5. Deselect Current project? and then double-click in the Project response. 6. Select TEMPLATES from the list and click OK . 7. Double-click the File response and choose the COLLAR_TEMPLATE file, which is the one you created in Exercise 3.1 8. Click Close to dismiss the Templates dialog, then click OK in the New File dialog. 9. The New file window will open with a file structure identical to the one for the COLLAR_TEMPLATE file. 10. Select Close and then click Yes when prompted. The new file will be created and immediately displayed in the File Editor. 11. Select File | Close or press the ESC key to close the file editor. You can see from this exercise how much time using templates can save, especially when you’re creating files with many fields. Additionally, using templates promotes consistent file structures both within and across projects. Copyright © Micromine 2004 Page 22
- 35. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) You can copy the contents of a template file, and the parameters in File | New can be saved as a form. This feature is extremely useful when you’re writing macros. You can also create a file in any form by right clicking on a file name, a field name, or by pressing F5. Notes: Modifying a File’s Structure In MICROMINE you can add and delete fields from a file at any time. If a field contains data when you delete it, the data will also be deleted. To add fields to a file or delete fields from a file, use the Modify function. The Modify function is located in the File menu of the main application window and the File Editor. You can also right-click (F6) on a File field in a dialog box and select Modify from the menu that appears. Exercise 3.3: Modify a file’s structure This task shows you how to prepare a file (containing the coordinates where surface samples were taken) for merging with the assay results from the laboratory. Do the following: 1. Select File | Open from the main menu. 2. Select MMI_NVG_GCM from the window that appears. If you can’t see it, make sure that Files of type is set to DATA . 3. Click OK to open the file in the File Editor. 4. Press F6 to modify the file, or alternately, close the file, then Select File | Modify from the File Editor menu and select MMI_NVG_GCM from the file list. 5. Position the cursor in the EAST_GRID field and press Ctrl+I or select Records | Insert Records from the menu. 6. Enter 6 in the dialog that appears, and then click OK .

Add the following fields to the file: Notes: Field Name Type Width Decimals AUAVE N 6 2 Au1 N 6 2 Au2 N 6 2 Au3 N 6 2 Ag N 6 0 Cu N 6 0 When you’ve completed the process, the file structure should look like this: 8. Select Close once the modification is complete. You’ll be prompted to Modify File? Select Yes. 9. Select File | Save As and save the file as NVG_GCM , if you have closed the file, select File | Open and save the file as NVG_GCM . 10. Select File | Close or press the ESC key to close the file editor. If you add fields to a file using Modify, no data will be lost. However, if you delete a field that contains data, the data will be lost. Copyright © Micromine 2004 Page 24

- 38. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) Notes: Lesson Three Summary This lesson has illustrated the following points: • Most data in MICROMINE is stored in files with a table structure. • When creating a file you must give the file a name and then define field names, field types, field lengths and number of decimal places. • You can use existing files as templates when creating new files. These templates can be in the current project, in another project, or in a folder on a local or shared drive. This promotes consistency and saves having to repeat work. To create a new data file from scratch: Select File | New and enter the files’ name and type, then Define the structure by specifying each field’s name, type, width, and number of decimals. To create a new data file using a template: Select File | New and enter the file’s name and type, then Set the Use template option and choose the template file. To modify the structure of an existing file: Select File | Modify and change the file’s structure. Good Practice Wherever possible use templates to create new file structures. You should create a set of template files and store them in a folder that has been set aside for that purpose. When you create a new file, retrieve a suitable template and use it to define the file structure.

- 39. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) Notes: Lesson 4 – Data Entry and File Processing Duration: 90 minutes The data that describes characteristics of a prospect or mine can be collected and recorded in a variety of ways. They include: survey data from total stations, rock sample data from geologists’ notebooks, drillhole data from portable data entry equipment, compass traverse notes, data files from aerial surveys and aerial photography. The challenge is to get all of this information in different formats into a project and into a coherent and useful state. This lesson describes some of the processes that can be used to get data into a MICROMINE project. After this lesson you’ll be able to: • Import text files into MICROMINE files (tables); • Merge assay results from the lab with their associated coordinates; • Link to data in an external database using ODBC; • Use Merge Lab Data to process a SIF file received from the laboratory; • Enter data in tables (data files) in the File Editor; • Navigate through the records and fields in the File Editor. Getting Data Into MICROMINE The Different Ways of Entering Data The File Editor is the primary tool you’ll use to create and maintain data files. While you can key-in data into the File Editor, it would be tedious to have to re- type data already in spreadsheets, external databases or in data files from assay laboratories. For this reason MICROMINE includes three ways to get large quantities of data into a project with a minimum of effort. These are: • Importing • Merging • Linking When you import data, all fields in the source file are included in the process. You can control which fields from the source data are written to the MICROMINE target file. To merge data, you select fields in a source file and merge them to the correct fields in the target file by matching values in a key field. You can also append the data. Copyright © Micromine 2004 Page 27
- 40. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) Notes: Merge Lab data is a “smart” function designed to process SIF (Standard Interchange Format) files supplied by many assay laboratories. Its flexible design means you can handle nearly any type of SIF file. When you link to a database you use ODBC to connect to an external data source. Generally Text Import is only used to transfer independent data sets into a MICROMINE project. The Text Merge function is used to re-establish relationships within data sets, for example, merging assay results with the coordinates at which the samples were taken. Before you begin using these techniques, it’s worth reviewing the different types of file that you’ll meet when you undertake these processes. Recognising Different File Types and Their Components There are a numerous types of text file but in general the types that you’ll have to deal with fall into two groups: delimited and fixed width. A delimited file contains rows of values separated by commas, if it’s a comma-delimited file, tabs if it’s a tab delimited file, and so on. Each row is terminated with a CR (carriage return) character and a LF (line feed) character. Fixed width files, sometimes known as column delimited files, contain values separated into columns made up of a fixed number of characters. Delimited files are generally more space-efficient, but human operators can more easily read fixed width files. Copyright © Micromine 2004 Page 28

Make sure you’ve completed Modifying a file’s struc ure .t Make sure you’re using the built-in file viewer. To ensure this is the case, select Options | Editor from the main menu and check that Built-in is selected in the Text Viewer group. Copyright © Micromine 2004 Page 29
- 42. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) Notes: Working with Dialogs and Forms Before we explore the methods of bringing data into MICROMINE, let’s look at the process of entering parameters into MICROMINE dialogs. So far, we’ve only seen the simplest of dialogs, but as you continue to learn MICROMINE you’ll encounter increasingly complex ones. Dialogs Some MICROMINE dialogs have over 50 individual controls arranged in numerous groups. The best way to fill out such a complicated dialog is to work through it as if you were reading down the columns of a newspaper: top down, from left to right. In the case of a tabbed dialog, you can extend the analogy to reading the pages of a magazine. Adopting a systematic approach like this ensures that responses are made in the correct order, which is important because other prompts on the dialog may change depending on your earlier choices. Much of MICROMINE’s user interface is geared towards maximising productivity whilst minimising effort. To help achieve this, numerous dialog shortcuts are available. We’ve already seen the right-click context menu, which is one such shortcut. Another involves the way you specify file or field names: Whenever MICROMINE prompts you for a file or field name, simply double-click it (or press F3) to select it from a pop-up list. You should never type a file or field name, since it’s very easy to mistype a name and produce an error. Once you’ve chosen a file name, MICROMINE will endeavour to automatically select all of the required field names, so you may not have to do this yourself. If a numeric field is selected, MICROMINE will also automatically calculate the minimum and maximum values of that field. Copyright © Micromine 2004 Page 30
- 43. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) In general, if a particular piece of information, such as a file name or a field name, already exists, you should choose it by double- clicking instead of typing. Notes: Some dialog prompts are highlighted in a different colour (usually red). These are compulsory prompts: You must enter a value before proceeding. Other prompts can be left blank if they’re not relevant. Form Sets MICROMINE provides an elegant way to save and re-use the parameters that you’ve entered into a dialog: You simply save them as a Form Set , which can be recalled for later reuse. A Form Set simply represents the saved contents of a dialog. To save the contents of a dialog as a form set, click the Forms button on the Dialogue form. Depending on the exact nature of the dialog, it may not have its own Forms button. For dialogue forms without a forms button, you can either click the Forms button under the Display menu, or use the Forms toolbar button. Dialogue boxes for many of the graphical display options such as Dhole | Normal sections do not have their own Forms buttons. MICROMINE will display the Forms dialog, which gives you the opportunity to save the parameters with a Title of your choice. The title can be any descriptive, plain English text, since all that MICROMINE needs to internally reference the form set is its Number, which must be unique. The Forms dialog Copyright © Micromine 2004 Page 31
- 44. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) also allows you to recall a previously saved form set, and import or export form sets for sharing with other users. Notes: Some dialogs have buttons that open other dialogs. In MICROMINE, the “parent” dialog is called a dialog fo m , and the “child” dialogs are known as dialog boxes . All dialog boxes that belong to a dialog form are automatically saved together with that particular dialog form. r Each MICROMINE function maintains its own independent list of form sets, so there’s no risk of duplication. For example, more than one function could have a form set Number 1, with the title “Testing”. Even if you forget to save a dialog as a form set, every MICROMINE dialog is automatically saved to a ‘default’ form set. Simply re-opening a particular dialog will automatically recall the default set, so your previous settings are always available, even after restarting the computer. As soon as you change a value, however, the previous value will be lost. Forms are a very useful facility. They promote consistency and save you from re-entering values. Exercise 4.1: Explore dialogs and form sets In this exercise, we’ll use the Simple Display function to display some geochemical sample locations and save the display parameters as a form set. 1. From the main menu, select Display | Simple. 2. Before choosing any data, click the Display Limits… button and confirm that the Display Limits dialog is empty. Close the Display Limits dialog. 3. Double-click the File response and choose NVG_GCM from the list. 4. Once you’ve chosen the file, re-click the Display Limits… button and note that the coordinate fields and their minima and maxima have been automatically set. Close the Display Limits dialog. 5. Double-click the small blank square next to the Symbol prompt and choose a plus [+] symbol. 6. Click the first OK button on the toolbar to run the function and test your settings. Most functions in MICROMINE use a Run button on the dialogue form to run functions, however, for graphical display functions such as Display | Simple, you run MICROMINE functions by clicking the first OK button on the toolbar. 7. Close the display window using File | Close, or the cross in the top right corner of the window to return to the dialog. Assuming you’re happy with the settings, you can now save them as a form set. 1. Click either the Forms menu or Forms toolbar button. 2. On the Forms dialog, click Save As. Copyright © Micromine 2004 Page 32
- 45. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) 3. When the Save Current Values dialog appears, type in the Title Geochem Display and click OK . Both dialogs will disappear. Notes: 4. Click the Forms menu or toolbar button a second time, and note that your newly saved form set appears in the list of saved form sets. If you wanted to re-use those settings, you’d simply click the appropriate form set to select it, and then click Open to load the settings. Merging Assay Data We added fields to the data file in Exercise 3.3 to prepare that file for the merging process. The NVG_GCM file contains a sample number, co-ordinates describing where the sample was taken, and some other information. A file called MMI_ASSAY_RESULTS.TXT (for convenience in the Import folder in the current project) contains the assay results and sample numbers that correspond to the coordinates. In this task we’ll merge the soil sample assays (MMI_ASSAY_RESULTS.TXT ) into the file containing the locations where the samples were collected (NVG_GCM.DAT ). To successfully merge the records in two files, there must be a field with the same values in both the target and source files. This is known as a key field . If the key field in each file contains duplicate values, you must use two or more fields in each file to differentiate each record. The Merge function processes the target file record by record. It finds the key field in each record and reads the value it contains. It then looks for the same value in the key field in the source file. When it finds an equivalent value, it takes the data from the fields you’ve nominated, and writes it to the corresponding fields in the target file. It’s important that you know the column order in which the sample data has been returned if the assay file does not contain a header row. In this case, the field order is: Au1, Au2, Au3, Ag, C u, Pb, Zn, Ba, Mo, Sb, As, Hg and Tl. Exercise 4.2: Merge assay data into a sample locality file In this exercise the sample identifiers are unique. This means you can use the fields containing sample identifiers in each file as the key field in the merge. In cases where there are duplicates in the key field in the target file you must use multiple fields to form the key. Do the following: 1. Select File | Merge | Text from the main menu (There’s also a Merge function under the Edit | Tools menu of the File Editor but it doesn’t have as many features as this one.) 2. Click the browse […] button beside the Text file path response and navigate to the file MMI_ASSAY_RESULTS.TXT in the Import folder (this file can be external to the project and is only here for convenience). 3. Double-click in the Target File response and select NVG_GCM from the window that appears. Copyright © Micromine 2004 Page 33
- 46. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) 4. Click Select. Notes: Defining the Key Field We know that the field containing the sample numbers is common to both files. And, because there are no duplicates in the SAMPLE field in either the source or target files, you can use SAMPLE as the single key field. To define the key field: 1. Select Use key fields and set Match to FIRST . 2. Click the Key Fields… button. 3. Position the cursor in the Start response on the first row, and then right- click. The contents of the source file will be displayed in the built-in text viewer. 4. Highlight the sample number (first column). Make sure that the highlight is extended to immediately prior to the first character in the next column. 5. Release the mouse button, and then click on Post Values; A 1 will be posted in Start and a 7 in Length. 6. Double-click in Target Field Name and select the SAMPLE field from the list. 7. Choose CHARACTER from the Match list and close the Key Fields dialog. Because we’re only using a single key field there’s no need to proceed to the next row. Defining the Merge Fields Copyright © Micromine 2004 Page 34
- 47. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) You must now define the merge fields. This is a very similar process to defining the key field. It involves defining: Notes: • The location of the first character in each field. • The number of characters in the field. • The name of the field in the target file where the merge value will be written. Do the following: 1. Click the Merge Fields… button. 2. Position the cursor in the Start column in the first row. 3. Right-click to open the file in the text viewer. 4. Highlight the second column on any row. Make sure that the highlight extends to immediately prior to the first character in the next column. 5. Click Post Values. 6. Select the field in the target file where that data will be written. 7. Repeat this process for each column you want to merge. In this case we want to merge them all. Copyright © Micromine 2004 Page 35
- 48. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) 8. Enter Unmerged in the Unmerged file response, Duplicate in the Duplicate file response, and Merge_s ats in the Report file response. These files will record the results of the Merge process. Notes: t Running the merge 9. The final stage of the process is to run the merge. Do this by clicking the Run button on the dialog box. When the process is complete, a report will appear describing the results of the process, which is reproduced in the Merge_stats file. Right-click the Unmerged and Duplicate files to check their contents. The Unmerged report will list the records in the source file that were not merged. The Duplicate report will list the records with duplicate keys. A useful check on any function that processes files is to right-click the output file and choose View from the pop-up menu. Any problems will become apparent and you can re-run the function after making the necessary corrections. Importing Text Files A popular format for text data is CSV (comma separated values). Most applications that can store and process tabular data can export in CSV format. For example, field data recorded in a geologist’s notebook is often transcribed from the notebook to a spreadsheet program such as MS EXCEL™ or Lotus™ before it’s imported into a MICROMINE project. CSV is generally used in these cases. If you use Field Marshal to collect field data, you can import or merge files in native MM format. Field Marshal and the File Editor contain many data entry and processing functions created specifically for earth science data. It’s cheaper and easier to buy Field Marshal or the File Editor than to try and write macros for MS EXCELor Lotus. Outlines are often used to record tenement boundaries. The tenement boundary data can be obtained from your local mines department. Generally this will be in the form of a series of distance, bearing pairs from a datum point. Exercise 4.3: Import a text file In this exercise you’ll create a file and import the (distance, bearing) pairs that were entered in an EXCEL spreadsheet and saved in CSV format. This exercise will also illustrate another MICROMINE productivity tool: You can create a new file virtually anywhere within MICROMINE. Choose the Text File 1. Select File | Import | Text from the main menu. 2. Click the browse […] button next to the Text file path response and navigate to the Import folder (within your project). Select the file MMI_Tenement_Data.csv . Copyright © Micromine 2004 Page 36
- 49. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) 3. Right-click the text file name to display it in the text viewer. Confirm that it’s in comma-delimited format, and determine which of the two fields is bearing and which is distance. Notes: 4. Set Text file format to COMMA DELIMITED . At this stage we can’t run the function because the target file doesn’t yet exist. Create the Target File You can create a new file right within most MICROMINE functions by using the right-click popup menu: 1. Right-click on the Output File response and choose New from the popup menu. 2. Following the same procedure as you used in Exercise 2.1, create a new file with the following parameters: Prompt Setting File TENEMENT_DATA Type DATA Title Tenement coordinates Use template Disabled 3. Create the following file structure: Field Name Type Width Decimals BEARING N 8 4 DISTANCE N 12 4 4. Close the editor and answer Yes to save the file. Select File | Close or press the ESC key to close the file editor. Note how MICROMINE automatically places the name of the newly created file into the Output File response. Modify the Field Order You’ll remember that the original text file contains data in Distance, Bearing order, but our new file uses the opposite field order. However, with MICROMINE we can easily control the order of the imported fields. 1. Click the Delimited Fields… button to display the Delimited Fields dialog. MICROMINE has no knowledge of what the fields in the CSV file represent, so instead it refers to them simply by their position in the file. For example, # 1 means the first field in the file, # 2 the second, and so on. 2. Double-click the Output Field response next to # 1 and set it to DISTANCE . Copyright © Micromine 2004 Page 37

Click the Run button on the dialog box to run the function. 5. Once the function has finished, right-click on the Output file and select View from the popup menu. Confirm that the fields are in their correct order. Connecting to an External Database Using ODBC ODBC is an acronym for the term O pen D atab ase C onnectivity. It’s simply an industry standard interface that allows data access from a variety of database applications. ODBC isn’t tied to a particular operating system or database program, but instead allows you to see your data in the same way irrespective of the underlying software. You’re able to link to the database of your choice simply by installing the desired drivers on your computer. Whenever you install a database product, the appropriate drivers are usually installed along with it. Setting up a new ODBC connection first involves creating a Data Source Name (DSN). There are three types of DSN, so the choice of which to use seems complex at first. In reality, they differ only in their degree of ‘visibility’ to the rest of the users on your computer or network. You need only create the DSN once; from then on it’s constantly re-used each time you reference the database. The three types of DSN are: • User DSN , which is local to a computer and is accessible only by the current user; User DSN: One user on one computer. Not available to other users. • System DSN , which is local to a computer but isn’t user-dedicated. In other words, it’s shared amongst all users of that computer; System DSN: Available to all users on one computer. • File DSN , which is shared among all users on a network. It’s neither user- dedicated nor local to a particular computer. File DSN: Available to all users on a network. Copyright © Micromine 2004 Page 38
- 51. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) On most computers, the User and System DSN’s are grouped under the category M a c h in e D a t a So u rc e . Notes: You can use an ODBC connection two ways in MICROMINE: You can either Import the data or Link to the database. When you Import , MICROMINE creates a ‘snapshot’ of the data. The files created in the MICROMINE project are ordinary data files, exactly the same as any other data file you’d create yourself. Because of this, the newly created files are independent of the database and can be used even if the connection to the database is lost. However, you must re-import the data if anything in the database changes. If you Link to an ODBC database, MICROMINE maintains a connection to that database. This means that if anything changes within the database, you can refresh your links simply by right clicking and choosing Reload Link from the popup menu. However, your access to the data will be lost if the connection to the database fails. Additionally, the underlying database sets the structure of linked data, so you can’t modify (or edit) the file. Exercise 4.4: Create an ODBC connection and import data In most cases you’ll probably want to create an ODBC link (by using File | Link | ODBC) so that MICROMINE always has access to the most up-to-date data from your company’s database. However, because we need to edit these files later, we’ll import the data instead. The training database contains four tables of drillhole data (collars, downhole surveys, assays, and lithologies), but we’re only interested in one of those: the assay table. To import the other tables you’d simply repeat the steps on the following page. To create the ODBC connection: 1. Select File | Import | ODBC. 2. Click the Select Data Source… button. 3. Select the Machine Data Source tab and click the New… button. 4. Select User Data Source and click Next >. 5. Choose Microsoft Access Driver from the list that appears and click Next >. 6. Click the Finish button. 7. Enter TRAINING as the Data Source Name and Introductory Training in Description. 8. Click the Select… button and navigate to the folder H: MMDATA TRAINING IMPORT . 9. Select MMI_DrillholeData.mdb and then click OK . 10. Click OK on the ODBC setup dialogs, until you reach the Select Table dialog, to complete the process. You’ve just created a new ODBC connection! You need only complete Steps 3 to 10 once, and from now on you’ll be able to reuse the same DSN each time you connect to the database. Copyright © Micromine 2004 Page 39
- 52. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) If you run into trouble with your ODBC settings, ask your system administrator for assistanc e. C onnection problems often stem from not having the correc t versions of ODBC drivers installed on your computer. You should also ask your system administrator to remove any unnecessary DSN’s. Notes: Loading Data from the External Database Whenever you want to re-use an existing DSN, you’ll need to complete the first three shaded steps in addition to the rest of the following procedure. However, because the Select Table dialog is already open, you don’t need to complete them for this example. Instead, you should progress directly to Step 14. 11. Select File | Import | ODBC. 12. Click the Select Data Source… button. 13. Select the Machine Data Source tab and choose TRAINING (the DSN you just created) from the list. Click OK . 14. The Select Table… dialog box will appear. You’ll see the names of the four tables in the database: ASSAY, COLLAR, LITHOLOGY and SURVEY. 15. Highlight the Collar entry and click OK . 16. Fill-out the remaining prompts in the dialog as shown below: Prompt Setting Target File NVG_COL Determine structure Selected Preview Selected Number of records 20 Select all Selected 17. Click Import. The contents of the Collar table will be displayed. If you’d like to change any of the characteristics of the file that MICROMINE will create, you can do it here. 18. Click OK . MICROMINE will create the new file in your project and populate it with the contents of the Collar table from the MS Access database. 19. Click Close once MICROMINE has finished importing the table. You have three choices when it comes to importing a data file. If you select Determine Structure MICROMINE will scan the database and determine the optimal data structure for the new file. If you select Use Database Structure MICROMINE will use the structure of the Database to create the new file. And finally if you select Use Current Structure MICROMINE will force the data to fit into the existing file. Copyright © Micromine 2004 Page 40

MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) Notes: Using Merge Lab Data Merge Lab Data is designed to process the SIF (Standard Interchange Files) files favoured by assay laboratories. It’s a very flexible function that can process most of the variations seen in SIF files. Merge Lab Data can: • Merge or append data from lab files into files in your project; • Create a target file in a project with the contents of the lab file; • Work with both comma delimited and column-delimited files; • Accommodate lab files with up to 130 fields; • Replace below detection assay codes with a standard code or, if the detection limit is specified in the SIF file, with the detection limit; • Replace laboratory codes with ones that are used in your company. Merge Lab Data can only merge on a single key field. If you need to use multiple keys, use File | Merge | Text. Exercise 4.5: Merge laboratory data into an assay file Defining the Contents of the SIF File To merge the contents of the SIF file: 1. Select File | Merge | Lab Data from the main menu. Copyright © Micromine 2004 Page 41
- 54. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) 2. Click the browse […] button next to the Lab file path response and select the MMI_ NVG.SIF file (from the Impo t folder). Notes: r 3. Back on the Merge Lab Data dialog, right-click the file name and view the file. Take particular note of the format (column or comma delimited?) and the particular codes found within the file. Close the text viewer window once you’re done. 4. Select Column Delimited . 5. Set the Method to Use sample field . 6. Because the sample numbers are in the first column, enter 1 in Start column. 7. Select Character match . 8. In the Assayed Element Names group, position the cursor in the Row response and right-click. Highlight the first column of element names in the header as shown in the preceding illustration. Click Post Values. 9. In the Data group, do the same for the first row in the column of assay values. The function assumes that the columns in the source file all have the same width. 10. Select Replace lab codes and click More… 11. Type NS into the first row of Lab Code, but leave Replace With blank. This will blank out all occurrences of the string ‘NS’ from the MICROMINE file. Copyright © Micromine 2004 Page 42
- 55. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) 12. Select Replace lab code in the Below Detection group and choose the Write <x.xx option. Notes: 13. Type LDL into the Lab code response. 14. Right-click in Detection limit row and highlight the first detection limit in the file header. Click Post Values. 15. Close the Replace Lab Codes dialog. 16. Type UM_report in the Unmerged file path response, and ML_stats in the Report file response. Defining the Characteristics of the Target File We’re going to merge the laboratory data into the assay interval file that you created in Exercise 4.4. Do the following: 1. Double-click the Target File response and choose NVG_ASSY from the file list. 2. Double-click the Sample field response and choose SAMPLE from the list. This is the name of the key field in the target file. 3. Select Overwrite existing data in case there’s any residual data in the target file. 4. Merge Lab Data uses the field names it finds given the information you entered in the Assayed Element Names group. When you click Assay Fields (1 - 65)… you’ll see the source file’s field names in the Source column, and target file’s field names in the Target column. 5. MICROMINE will endeavour to automatically match the source and target field names. However, you may need to “tune” this process by selecting the appropriate Target fields. Also, if the Source column contains incorrect values, return to the Assayed Element Names group and re-define the field names. 6. Close the Assay Fields dialog once you’re done. 7. Click OK to run the function. 8. Right-click the NVG_ASSY file name and check the contents of the assay fields. Note how previously blank fields have now been populated with data. Data Entry MICROMINE’s File Editor is an excellent data entry tool that’s specifically designed to provide numerous tools for the rapid entry of spatial and drillhole data. For example, by defining a series of rules, you can enter drillhole collar coordinates and downhole sample data with a minimum of keystrokes. Although many people use a spreadsheet application for data entry, you’ll find that the File Editor provides a safer and more rapid data entry environment. Copyright © Micromine 2004 Page 43
- 56. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) The File Editor has a Tools menu available under the Edit menu that contains a collection of basic functions for importing, exporting and merging data; sorting and validating files; and performing field-based calculations. Many of these tools also have toolbar buttons. Notes: MICROMINE files are presented on-screen in a familiar grid layout. You can navigate up and down through the file by using the keyboard up and down arrow keys, as well as Pg Up and Pg Dn to go one page at a time. Of course, you can scroll using the mouse, too. To move from one field to the next, press Tab or Shift+Tab, or click into the desired field with the mouse. To create a new record, simply press Enter at the end of the file. The File Editor supports standard Windows shortcuts for editing text, for example: • Ctrl+C (Copy) • Ctrl+X (Cut) • Ctrl+V (Paste) Using these shortcuts, you can easily transfer blocks of data between MICROMINE and, say, MS Excel, in either direction. However, the File Editor also provides many other unique shortcuts that are designed to automate repetitive geological data entry tasks. You can access these shortcuts by opening the Records menu. Some of these are summarised in Table 1 below: Table 1: File Editor keyboard shortcuts To… Keyboard Menu Button Increment contents to the cell below Ctrl+A Records | Add | One Set Increment value Ctrl+Shift+I Records | Increment Copy contents to the cell below Ctrl+R Records | Replicate | One Operate on multiple fields to record below Ctrl+T Records | Execute | One Define Ctrl+T parameters Ctrl+Shift+ P Records | Execute | Parameters Delete records Ctrl+D Records | Delete Insert blank records Ctrl+I Records | Insert The add (Ctrl+A), replicate (Ctrl+R) and execute (Ctrl+T) tools also operate on multiple records, by pressing Ctrl+Shift+[Letter] instead of Ctrl+[Letter]. Copyright © Micromine 2004 Page 44
- 57. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) These standard shortcuts all have a matching toolbar button, so feel free to access these if you prefer to use the mouse instead of the keyboard. Notes: Exercise 4.6: Use the File Editor’s data entry tools Let’s put some of these tools to work. This exercise always refers to the keyboard shortcut for each function, but please feel free to experiment with the menu or toolbar if you’d prefer to use the mouse. Data Entry Field‐by‐Field 1. From the main MICROMINE menu, select File | Open and open the NVG_ASSY file. Alternatively, you can click the Open File toolbar button. 2. Scroll to the bottom of the file and select (click) the last HOLE value, which should read T17 . 3. Press Ctrl+A. Observe how MICROMINE creates a new record, recognises that the existing text T17 contains a numeric component, increments that component by one, and places the new value into the new record. 4. Now press Ctrl+R four or five times. Each time you choose this command it replicates the T18 value to the record below. Copyright © Micromine 2004 Page 45
- 58. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) Notes: 5. Select (click) the first blank FROM value in your new T18 hole and type in a value of 0 (zero). 6. Press Ctrl+Shift+I and change the increment from 1 to 4 . Click OK . 7. With the highlight still on the zero value, press Ctrl+Shift+A. The Increment Many dialog will appear. Just click OK to accept the default values. 8. Observe how MICROMINE has applied the new increment value to all records below the selected cell. 9. Select the first blank TO value, type a 4 into that cell, and repeat the Ctrl+Shift+A function. Your file should now resemble the following diagram: That was pretty quick, but wouldn’t it be good if you could perform all of those actions simultaneously? Fortunately, there is a way. Copyright © Micromine 2004 Page 46
- 59. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) Simultaneous Multiple Field Data Entry Notes: 1. Press Ctrl+Shift+P to display the Execute Parameters dialog. Using this dialog, you can define a separate “rule” for each field in the file. Once they’re defined, you can apply them all simultaneously. 2. The HOLE field on the Execute Parameters dialog should already be selected, but if it isn’t, click it to select it. 3. Click the Replicate button. Note how MICROMINE changes the “rule” for the HOLE field from IGNORE to REPLICATE . 4. The SAMPLE field is now automatically selected, so just click the Increment button. When the Increment dialog appears, leave the value set to 1 and click OK . 5. The FROM field now becomes the selected field. It’s tempting to set an increment value of, say, four, but there’s a much smarter way to handle this field: Click the Copy button instead. 6. When the Copy Field dialog appears, select TO from the list and click OK . This will take the TO value from the previous record and copy it into the FROM field in the current record. Copying the previous TO value into the FRO M field is an excellent way to ensure that your interval data has no gaps or overlaps. Even if you manually edit a TO value, the next FRO M value will alwaysbe correct. 7. With the TO field selected, click the Increment button and set the increment value to 4 . Your Execute Parameters dialog should now look like this: Copyright © Micromine 2004 Page 47
- 60. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) Notes: 8. Click OK to close the Execute Parameters dialog. 9. Select the last T18 value in the HOLE field and press Ctrl+A. This will start a new hole. 10. Manually type in a SAMPLE number of S00001 , a FROM of 0 and a TO of 4 . Your file should now look something like this: Before you can use the execution parameters, you must always have a “starter record” containing actual values. The cursor must also be somewhere in thisrecord before creating any new data. 11. Press Ctrl+T and observe the result: All of the rules have been applied simultaneously. Press Ctrl+T a couple more times to add some more records. Your file should now look like this: If you know how many records you need to add (you might be drilling a series of 100m Reverse C irculation holes, for instance), you can scroll to the end of the file, press Ctrl+Shift+T, and type the number of new records into the Execute Many dialog. Calculator You can use the Calculator to quickly fill out fields through out a file. You can perform simple algebra or more complex data manipulation. The calculator works by the following formula: Input A Calculation Function (ie Plus, Minus, etc) Input B = Result Copyright © Micromine 2004 Page 48
- 61. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) Both Input A and Input B can be field names, numbers or a temporary variable. The result can be a new field, existing field or a temporary variable. Notes: To access the Calculator you can either select the File | Fields | Calculate menu or by clicking the Calculations button on the toolbar in the File Editor. The File Editor Calculator is slightly different to the main calculator as it has fewer fields. Exercise 4.7: Using the Calculator 1. Click the Calculations button on the toolbar. 2. Double click the first Input response and select the TO field. 3. Click the Function response and select Minus. 4. Double click the second Input response and select the FROM field. 5. Double click the Result response and select the INTERVAL field. The dialog should resemble the following diagram. 6. Click Ok to run the Calculator. If you need to perform more complex calculations the temporary variables become an invaluable tool. It’s useful to think of a temporary variable as being the same as the Memory button on a standard calculator, the only difference being that you have nine (labelled #1 to #9) instead of the standard one. Let’s perform an exercise to calculate the Mid Point of each sample interval. 7. Change the Function from Minus to Plus . 8. Single click the Result response and clear the box (Shift+Space) and type in #1 to create a temporary variable. 9. Click the first Input on the second row and type in #1 to reference the temporary variable. Copyright © Micromine 2004 Page 49

In the second Result field type in MidPoint. This will create a new field in the data called MidPoint , which will be populated by the mid point of the hole interval. 13. Click OK to run the calculation. You’ll be prompted to create the new field; answer OK to create it. 14. Close the File Editor once you’re satisfied with the result.

MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) Notes: Lesson Four Summary The key points of this lesson are: • There are several ways of getting large quantities of data into MICROMINE. These are Merge Lab Data, Merging, ODBC connection, ODBC Linking and Importing text files. • If you only need a single key field to differentiate between records in a source and target file, Merge Lab Data has many useful features. To merge using more than one key field you must use the Merge function in the File menu. • The File Editor can be much more efficient than spreadsheet applications for entering spatial data. To fill out a MICROMINE dialog: Work through the settings as if you were reading columns in a newspaper. To save a dialog as a form set: Click Forms, followed by Save As. To merge data into an existing MICROMINE file: Select File | Merge | …, then Define Key Fields and Merge Fields. To import a text file: Select File | Import | Text and choose the input text file’s format, then Create the new MICROMINE target file. To access data via an ODBC connection: Select File | Link | ODBC or File | Import | ODBC, then Create or select a Data Source Name (DSN), then Select the table(s) and type a target file name. To merge SIF laboratory data: Select File | Merge | Lab Data, then Define the input file’s format and identify the various fields, plus Define any code replacements, and Match the input field names to the target field names. To Calculate a value for a Field: Select File | Fields | Calculate or the Calculate Toolbar Button. Define the two Inputs and Select a Function, plus Choose a result field or a temporary variable.

- 65. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) Notes: Lesson 5 – Validating Data Duration: 60 minutes Validation is an essential processing task, with two primary objectives: • To eliminate incorrect values from a file; • To enhance the consistency of the data. Many companies use a centralised corporate database to store their corporate and scientific data. If your company uses such a system, it places increased pressure on you to ensure that your data are valid and consistent before uploading into your Database Management System (DBMS). Companies are also becoming increasingly aware of the value of their data, which is also encouraging good validation processes. At a simpler level, some MICROMINE functions may produce undefined results if they encounter invalid data. After this lesson you’ll be able to: • Create a validation file; • Validate a data set; • Validate a drillhole database; • Create and use a lookup table. Before you continue... Make sure you’ve completed Lesson 2 – Working with data files . Validating Data in a Project Validation MICROMINE supports the validation of nearly all types of fielded data (with the obvious exception of fields containing random comments) and can also perform rigorous validation of drillhole data. There are three validation functions in MICROMINE: • Validate in the Tools menu of the File Editor (File Editor: Edit | Tools | Validate). • Validate under the Fields item in the File menu (Main menu: File | Fields | Validate). • Validate in the Dhole menu (Dhole | Validate). The first two validation options are designed to validate the contents of fields in a file, whereas the last is designed to validate drillhole data. Copyright © Micromine 2004 Page 53
- 66. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) Validating a Data File Notes: You have two choices for validating fields in a file: Either Tools | Validate or File | Fields | Validate. With Tools | Validate, you can only validate one field at a time, but it’s easy to use because you can validate at the same time as you’re editing the file. File | Fields | Validate is a more powerful function because it can simultaneously validate up to ten fields, plus you can set validation ranges on numeric fields. You’ll use this function in this lesson. The Validate function can check up to ten fields in a target file for correct values. If it finds an incorrect value, it will write an error message to a report file, along with the name of the field in which the error was found, and the number of the record. For character fields the function determines which values are correct or incorrect by comparing them with entries in a validation file. You must have previously created the validation file. For numeric fields the function determines which values are valid by testing if they fall within the ranges that you specify. Exercise 5.1: Validate fields in a file Validation is often used to check the consistency of lithology codes used to describe sample data. In this exercise you’ll create a validation file that contains a list of the valid lithological codes that are relevant to the lithology file. You’ll then use it to validate the lithology file. Creating the Validation File Although you could create the validation file using the File Editor, there’s no reason to re-type data that already exists in some form. In this exercise, the lithology codes are already present – including errors – in the lithology file itself. So, it makes sense to extract the codes from the file, remove the errors, and then use the corrected codes as our validation file. If your company uses a corporate database, you should be able to create validation files by importing the various lookup tables that are part of the database. To extract the codes from the lithology file: 1. Select File | Fields | Extract Unique from the main menu. 2. Set up the Extract Unique Records dialog as shown below: Copyright © Micromine 2004 Page 54
- 67. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) Notes: Prompt Setting File NVG_LITH Type DATA Extraction field LITH Case sensitive Set Sort output Set Numeric (ignore…) Cleared Output File VALID_LITH Output Type DATA 3. Click RUN to run the function. MICROMINE will immediately display a File Editor window containing the results and counts of the extraction. You can see that although there were over 400 records in the original file, fewer than ten different codes were used. 4. Before you can use this file, you must remove the errors! We’ll consider blank or un-logged intervals to be errors, so highlight the blank record and press Ctrl+D to delete it. 5. Highlight the FAUT record and press Ctrl+D to delete it also. The remaining codes are correct. We now need to modify the file slightly to improve the clarity of the remaining steps. 6. Select F6 to modify the file. 7. In the Modify window, double-click the LITH field name and change it to LITHOLOGY . 8. Highlight the FREQUENCY field name, and pres Ctrl + I to insert a record so that your Modify screen looks like this: Field Name Type Width Decimals LITHOLOGY C 10 0 LITH_DESC C 50 0 FREQUENCY N 8 0 9. Close the Modify window when you’re done, and answer Yes to modify the file. 10. Fill out the LITH _ DESC values so that the file resembles this illustration: Copyright © Micromine 2004 Page 55
- 68. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) Notes: The descriptions serve no functional purpose for the validation operation. However, they make it easier for you to understand the codes, and this file can be used as the basis for creating a lookup table, which is described in a later lesson. 11. Finally, Close the File Editor window, answering Yes when prompted to save the file, and close the Extract Unique Records dialog. Validating the interval file The check file is used to validate the contents of fields where there is a fixed set of possible results. You can also use the validation function to determine if the contents of numeric fields fall within a range of values you specify. Range checking helps to eliminate typographical errors and other mistakes that often occur in data entry. In the next exercise, we’ll check a field that contains values that range between 0 (zero) and 75. 1. From the main menu, select File | Fields | Validate. The Fields Validate dialog is split into two halves: The upper half allows you to set up the input, validation, and report files, whereas you define the various validation rules in the lower half. 2. Fill out the upper half of the Fields Validate dialog as listed: Prompt Setting Input File NVG_LITH Type DATA Data type DRILL HOLE Check file VALID_LITH Type DATA Report file INVALID_LITH Copyright © Micromine 2004 Page 56
- 69. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) 3. Now, set up the lower half as shown: Notes: When you select Case Sensitive, values in the file you’re validating must match the case of your check file, otherwise they’ll be recorded as invalid. For example, ANDS is seen as being different to ands or Ands . 4. Click the OK button on the toolbar to run the process. 5. Right-click in the Report file response and select View from the popup menu. 6. The Report file will look something like this. From here you can go to each of the records in the input file that have an error and correct them. Copyright © Micromine 2004 Page 57
- 70. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) Notes: Validating Drillhole Data The drillhole validation function (Dhole | Validate) will detect a large number of errors and inconsistencies in Collar, Interval and Downhole Survey files. It detects: FROM < previous TO Duplicate collar entry FROM >= TO Dips or Azimuths change by more than x FROM or TO missing Surveys beyond total depth Collar missing or incorrect Missing hole in interval file Record beyond total depth Compulsory field blank Hole excluded by collar filter Total depth missing Duplicate hole Rate of Deviation Non-consecutive surveys Sample Interval Lengths MICROMINE performs this validation by checking the relationship between the three files and the relevant fields, as illustrated below. For example, it checks for missing holes by listing the hole ID’s it finds in each file and then checking to see if any are missing from any of the three files. As you can see, the drillhole data undergoes comprehensive testing. You should always validate drillhole data to ensure trouble free operation in later processes. Copyright © Micromine 2004 Page 58
- 71. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) Interval files are drillhole or trenc h files containing From-To data. You must perform a separate validation run for each interval file that you’re checking, using the same collar and downhole survey file in each case. For example, if you have interval files for assays, lithologies, and oxidation, you must perform three separate runs of Dhole | Validate. Notes: Exercise 5.2: Validate drillhole data To validate the drillhole data, do the following: 1. Select Dhole | Validate from the menu. 2. Make the following entries on the DH Validation dialog: Prompt Setting Collar file NVG_COL Type DATA (use for all files) Survey file NVG_SUVY Interval file NVG_ASSY Report file DH_VALID 3. Click Options and make the following settings: Prompt Setting Check for missing intervals Selected Check for missing holes Selected Check for duplicate holes Selected Check dips Selected Check azimuths Selected Check maximum deviation Selected Check sample Interval Lengths Selected Valid azimuth change 5 Valid dip change 5 Valid dip change 5 Max interval Length 5 Grade Field Blank Copyright © Micromine 2004 Page 59
- 72. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) You can choose to ignore unsampled intervals for the interval length check by selecting a grade field. Any intervals with a blank for the grade field will be ignored for the validation check. Notes: 4. Click OK . A series of status messages will appear as Validate processes the drillhole files. If an error is detected, an appropriate message will be displayed and the error will be written to the Report file. 5. Right-click the Report file and select View from the popup menu. This file contains a record of all errors encountered during the validation process. In this exercise, Validate detected some downhole survey errors, caused by consecutive surveys deviating by more than 5°, and some errors for sample intervals greater than 5m. These downhole survey errors could in fact consist of valid data, so it’s entirely up to you to determine whether or not corrections are required. If you were to re-run the validation using the NVG_LITH interval file, you’d discover some inconsistent data in the interval (lithology) file. These interval errors will require attention before the data can be used. However, the training dataset already contains a validated file (NVG_LITH_NO_ERR ), so the corrections won’t be necessary. You’ve probably noticed that MICROMINE knew the names of the fields in the drillhole files. You can set the field names that MICROMINE allocates to dialog prompts by selecting Options | Forms from the main menu. Here you can enter the names you use for the fields at your site. However, it’s still good practice to click each of the Fields… buttons and check that the fields have been correctly allocated! Using Lookup Tables So far we’ve looked at validating pre-existing data, but it would be far better to ensure those data were correct from the moment they were created. Using MICROMINE’s Lookup Tables, you can establish a data entry environment where this is possible. Lookup tables serve two main purposes. Firstly, they act as a data entry tool, minimising the amount of typing required. Instead of having to type a particular code, for example, you can simply choose it from a list. When used in conjunction with the other data entry shortcuts that we’ve already explored, lookup tables make it possible to enter large quantities of data with few keystrokes. This system works particularly well with pen-based devices such as palmtops or PDA’s, which may not have a keyboard. Secondly, and perhaps more importantly, lookup tables act as a data validation tool. Keystrokes are validated as they occur, which ensures that your data are correct from the start. There are numerous settings that control the way lookup tables perform this validation task. Lookup tables can be attached to any field in a MICROMINE file. Once attached, they appear as an ellipsis […] button in each cell of that field. Lookup tables remain active until they are detached. Copyright © Micromine 2004 Page 60
- 73. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) Types of Lookup Table Notes: You can create two different types of lookup table: Either a Flat lookup table, which consists of a single list of codes and descriptions, or a Hierarchical lookup table, which consists of nested lists of code/description pairs. Each form of lookup table is better suited to a particular type of data. Flat Lookup Tables Flat lookup tables are suited to simple lists of codes and descriptions, like the logging geologists’ initials or simple geological codes. In fact, anything consisting of a list of discrete values could be used. Hierarchical Lookup Tables Hierarchical lookup tables are best suited to more complex data where there is a distinct hierarchy in the codes. Standard Geological Survey codes are an excellent example, where they have nested levels for Age, Primary Rock Type, and Lithology. Other examples include dates, with nested levels for Year, Month, and Day, and tenements, with levels for type, mineral field, and number. Creating a Lookup Table Creating a lookup table is a two-stage process. Firstly, the lookup table is created as an ordinary MICROMINE file with an LDT file extension. Once the codes have been entered or otherwise imported, the second stage involves ‘compiling’ the lookup table into a binary file with an LBN file extension. The binary file can’t be viewed or edited by a user, and so is much more secure than the text file version. Exercise 4.3: Create and attach a new lookup table Let’s create a lookup table that we’ll use on the NVG_LITH file. Copyright © Micromine 2004 Page 61
- 74. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) Creating the MICROMINE File Notes: 1. Select File | New from the main menu. 2. Set the prompts as shown: Prompt Setting File LITH_LOOKUP Type LOOKUP Use template Cleared Define nesting levels Set (with a value of 1) Define nesting levels is based on the desired hierarchy, so if you wanted to create a three level hierarchy, you’d set thisvalue to 3 . 3. Click OK to create the new file. Because we defined the nesting levels, MICROMINE has already set up the file structure for us. At this point, we could manually enter the codes and descriptions, but it makes sense to re-use the available data. The validation check file VALID_LITH already contains the codes and descriptions we need, so let’s save some time by using that file. 4. Keeping LITH_LOOKUP open, select File | Open from the File Editor menu and open the data file VALID_LITH . (If you can’t see it, be sure to set Files of type to DATA .) Both files are now open simultaneously. 5. Drag your mouse over all of the cells in the first two columns of VALID_LITH to select them, and then press Ctrl+C to copy the selected data. 6. Close the VAL D_LITH file and ensure that the first cell of LITH_LOOKUP is selected. I 7. Press Ctrl+V to paste the data into the lookup table. It should look like this: 8. Select File | Save to save the lookup table. Copyright © Micromine 2004 Page 62
- 75. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) Compiling the Binary File Notes: The MICROMINE file version of the lookup table is what you’ll edit and maintain as administrator of this project. However, it’s not the file that the geologists in the field will use. You must compile this file into a binary LBN file before it can be attached to an interval file. To compile the lookup table: 1. With the file open in the editor, select File | Compile from the menu. The Lookup Table Properties dialog will appear. 2. Set the Enable validation and Case sensitive options, but leave the remaining options blank. 3. Click Compile to create the binary LBN file. A message will appear indicating successful creation of this file. 4. Close the File Editor window. Attaching the Lookup Table to a Field in the Data File The final stage in this process is to attach the lookup table to the appropriate field of the NVG_LITH file. Once this is done, we can start using it. 1. From the main menu, select File | Open and open the NVG_LITH file. 2. Click the LITH field to select it. It doesn’t matter if you click the field heading or just a cell in that field. 3. From the File Editor menu, select Format | Lookup Tables | Attach. 4. Choose LITH_LOOKUP from the list and click Open. MICROMINE will add the ellipsis buttons to the LITH field displayed in the File Editor. If desired, you could attach a lookup table to every field in a file. You can also attach the same lookup table to more than one field. For example, your file could have C olour1 and Colour2 fields. Simply attac h your Colour lookup table to both! 5. Click one of the ellipsis […] buttons to open the lookup table. Your screen should resemble the following diagram. From here, you can simply click the desired code to select it. Copyright © Micromine 2004 Page 63
- 76. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) 6. Instead of clicking, try typing a code into one of the LITH cells. Even though the lookup table is attached, you’re not prevented from using the keyboard in the conventional manner. Notes: 7. Try typing an incorrect code, then moving the cursor to a different cell in the file. The invalid code is accepted! There’s still one final stage we must complete before the lookup table is fully set up as a validation tool. Setting the Validation Behaviour In addition to setting the Enable validation switch when you create a lookup table, you must also inform the File Editor that it must support validation. You can set this behaviour by selecting Options | Editor from the main menu. 1. Close the File Editor window. 2. From the main menu, select Options | Editor to display the Editor Options dialog. 3. This comprehensive dialog has many settings on it, but we’re interested in the lower half, which is dedicated to setting the validation options. 4. Set the Validate lookup fields option. This will activate the remaining prompts. 5. In the Validation options group, set the Beep when validation fails option. 6. Finally, in the Validation actions group, ensure that the Valid inpu compulsory option is selected. Your dialog should look like this: t Copyright © Micromine 2004 Page 64
- 77. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) Notes: 7. Close the Editor Options dialog. 8. From the main menu, select File | Open and re-open the NVG_LITH file. Note how the lookup table is still attached. 9. Type an invalid code into one of the LITH cells and then move the cursor on to a different cell. 10. Observe how MICROMINE now displays a message (and beeps!) informing you that the entered value is incorrect. Because of the validation options we chose, you can’t proceed any further without correcting the offending code. If you’d prefer to take a more flexible approach, you can choose to flag incorrect codes for later correction instead. Simply choose the desired action in the Validation Actions group.

MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) Notes: Lesson Five Summary These are the key points of this lesson: • To ensure consistent results you must validate data before using it. • Validation is a prerequisite for data that will be stored in a central repository. • Validation processes can be automated on sites where code usage is consistent. • Drillhole data should be validated before using it in other drillhole processes. • Lookup table serve dual roles as data entry and data validation tools. To validate the contents of a file: Select File | Fields | Validate, and Select the file to be validated, and the check file, then Define the validation rules. To validate drillhole data: Select Dhole | Validate, and Select the collar, downhole survey, and interval files, then Select the desired validation rules. To create a lookup table: Create a new LOOKUP file, defining nesting levels if required, then Enter the lookup codes and descriptions in the File Editor, then Select File | Compile from the editor to create a binary LBN file. To attach a lookup table: Open the desired file into the File Editor, then Click on the desired field, then Select Format | Lookup Tables | Attach, and Choose the desired lookup table. To set validation behaviour: From the main menu, select Options | Editor, and Set the Validate lookup fields option. Copyright © Micromine 2004 Page 66
- 79. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) Notes: Good Practice • If you’re processing many files containing similar codes, you can create validation files and re-use them. • You should always run drillhole validation after adding any new drilling data or after importing it or reading it from other systems. Most problems people have with drillhole displays are due to errors in the data that Validate will identify.

- 80. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) Notes: Lesson 6 – Filters Duration: 30 minutes Filters in MICROMINE allow you to subset data of interest from a larger dataset. This might prove useful, for instance, if you only wanted to work with drillholes drilled during 2001. Most MICROMINE functions have a filter option, and the filters themselves can be saved as form sets. As we’ve already seen, form sets allow us to re-use previous settings. Saving filtersas form sets is an essential practice for macro writing, as it allows for “conditional” execution – in other words, running a process only on the subset records. Macro writing is introduced in M o d u le 5 : M a c ro s 1 . After this lesson, you’ll be able to: • Set up a filter from within another MICROMINE function; • Preview the filter result in the File Editor; • Create complex filters using Boolean algebra. Working with Filters Setting up a Filter If you’d like to work with filtered records instead of a complete dataset, simply set (turn on) the filter option on the appropriate dialog: Once you’ve activated the filter, you can edit the filter conditions by right clicking (or pressing F4) on the filter number. In the illustration above, the filter number is currently blank, but after you’ve saved the filter as a form set, a Copyright © Micromine 2004 Page 68
- 81. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) number will appear in this response. To choose an existing filter, just double click (or press F3) the filter number and choose the form set from the list. Notes: The Filter Dialog The Filter dialog is divided into two main areas: A variety of settings at the left and bottom of the dialog, and up to 10 filter conditions in the Filter Conditions group. If you open a filter from within another function, the filter will automatically choose the correct file and place it into the appropriate response. The remainder is up to you. The Records group allows you to subset by record numbers (say, records 0 to 100 ). It’s very easy to accidentally leave this option set, so please remember to clear it afterwards! In the event that a filter gives you exactly everything you don’t want, simply use the Reverse filter option to invert the filter result. To specify a particular condition, you must provide three items of information for each Filter Condition line: A Field Name , an Operator , and a Value . For example, consider these settings: This filter condition will return the points whose easting is greater or equal to 24900. The field name is EAST_GR D (chosen by double-clicking), the operator is >= , and the value is 24900 (entered by typing). Setting the Numeric switch instructs MICROMINE to ignore any character values that may be in the field. I Matching Records Once you’ve set up a filter, you can immediately preview the results in the File Editor by right-clicking the file name, or any of the referenced field names, and Copyright © Micromine 2004 Page 69
- 82. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) selecting View from the popup menu. The records on a white background are those that matched the filter conditions. These are the ones that will be used for further calculations. The records on a grey background did not match the filter, and will be excluded from the calculation. Notes: Multiple Filter Conditions The Filter dialog allows you to define up to 10 filter conditions. In this event, you must choose a Boolean operator such as AND or OR. As soon as you define two or more conditions, the Combine Lines group becomes active, which allows you to choose the desired Boolean operator. Sometimes you need to might define a filter that’s too complex for a simple AND/OR combination. Complex filters such as this require that you use the Equation option instead. You write an equation by typing it into the Equation response, referring to each filter condition by its line number. You then use a combination of character codes (listed in Table 2) in conjunction with your line numbers. Let’s use an example. Suppose you had defined the filter conditions illustrated in the screenshot earlier in this section, but wanted to combine them using an equation. The conditions were: • 1. EAST_GRID >= 24900 • 2. EAST_GRID <= 25000 Copyright © Micromine 2004 Page 70
- 83. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) Notes:To set up an equation relating these with the Boolean AND operator, you’d type this into the Equation response: • 1&2 If you wanted to use Boolean OR instead, you’d type: • 1|2 Table 2: Filter equation operators Code Meaning & AND | (pipe) OR * Any characters ? Any single character ( ) Set precedence Note: You type the pipe (|) symbol by pressing Shift+ on the keyboard You can construct quite complex filters using this technique, but in order to use it effectively you should have an understanding of the underlying Boolean algebra. Using Boolean Algebra As we’ve seen, you create a filter equation by using combinations of your filter conditions and the Boolean AND and OR operators. It’s therefore important to understand how each operator works. Boolean AND is a “restrictive” operator. In other words, every condition you specify must be met in order to satisfy the overall filter. For every new condition that you add, the filter becomes more difficult to satisfy. On the other hand, Boolean OR is an “expansive” operator. Only one of the conditions needs to be met to satisfy the overall filter. It doesn’t matter which one. Therefore, for every new condition that you add, the filter becomes easier to satisfy. Area common to BOTH circles matches AND Area belonging to one, the other, or both circles matches OR Copyright © Micromine 2004 Page 71
- 84. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) Imagine adding a third overlapping circle to each of the two diagrams above. In the AND diagram, left, the area common to all three circles will be smaller than the shaded area currently common to the existing two. The conditions are becoming harder to satisfy. On the other hand, adding a third overlapping circle to the OR diagram simply increases the shaded area, making the conditions easier to satisfy. Notes: Exercise 6.1: Create a multiple condition filter Let’s put a filter to work. We’ll revisit the Simple Display function so that we can graphically illustrate the results of our filters. Our first task is to create a filter to subset all geochemical samples whose coordinates fall within the following ranges: • 15900 – 16000N • 24900 – 25000E Here’s how to do it: 1. From the main menu, select Display | Simple. The Simple Display dialog should have retained our settings from Exercise 4.1. If it’s blank, you can fill it out by referring to the first half of that exercise. 2. Click the Display Limits button and set the Grid type to FULL . Close the Display Limits dialog. 3. Set the Filter check box to activate the filter option. 4. Right-click (or press F4) the blank filter number to edit the filter. The Filter dialog will appear. 5. The filter dialog may still contain settings from a previous filter. Simply blank out any existing filter conditions before continuing. 6. Double-click the first Field Name response and choose NORTH_GRID from the list. 7. Set the first Operator to >= . 8. Type 15900 into the first Value response and set the Numeric check box. 9. Repeat Steps 6 through 8 for the remaining filter conditions. Your filter should now look like this: Copyright © Micromine 2004 Page 72
- 85. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) 10. Set Combine Lines to And . Notes: 11. Preview the filter by right clicking on the File response and choosing View from the popup menu. Scroll through the file and confirm that most of the records are on a grey background, with a small number of matching records on a white background. If this isn’t the case, you’ll have to correct your filter. 12. Close the File Editor window and then click OK to close the filter. 13. Click OK on the toolbar to run the Simple Display function. Your display should resemble the following diagram: 14. Close the graphic display window. Exercise 5.2: Create a more complex filter Let’s create a slightly more complex filter. This time, our task is to subset all geochemical samples whose sample numbers fall within the following ranges: • IV10680 – IV10691 • NV10295 – NV10314 Follow these steps: 1. Right-click the filter number to redisplay the Filter dialog. 2. Position the cursor in the first Field Name response and repeatedly press Ctrl+Space until all of the filter conditions are empty. 3. Double-click the first Field Name response and choose SAMPLE from the list. 4. Set the first Operator to >= . 5. Type the string IV10680 into the first Value response, and clear the Numeric switch. Copyright © Micromine 2004 Page 73
- 86. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) Notes:6. Repeat Steps 3 to 5 for the remaining filter conditions. You filter should now resemble this: 7. After some consideration it should become apparent that a combination of both Boolean AND and OR is required, so we must therefore use an equation to create this filter. 8. Change Combine Lines to Equation . 9. Type the following equation into the Equation response: (1&2)|(3&4) 10. To preview the filter, right-click the File response and choose View from the popup menu. Confirm that the desired samples are indeed selected, i.e. on a white background. 11. The graphical output of this function is meaningless so simply close all of the dialogs once you’re satisfied with the result. Copyright © Micromine 2004 Page 74
- 87. MICROMINE Training v9.2Module 01 – Micromine Basics (Rev 05) Notes: Lesson Six Summary These are the key points of this lesson: • Filters are an extremely versatile way to subset only the data of interest from a larger dataset. • Most MICROMINE functions have a Filter option. • Filters can be saved as form sets, which allows them to be re-used. • Multiple filter conditions must be combined using a Boolean operator. To create or edit a filter: Turn on the Filter option on the appropriate dialog, then Right-click the filter number to edit it. To define a filter condition: Specify a Field Name, an Operator, and a Value. To preview the filter result: Right-click the File response and choose View from the popup menu, then Observe the relationship between records on white (selected) and grey (not selected) backgrounds. To combine multiple filter conditions: Set Combine Lines as desired. To build a filter equation: Refer to each filter condition by its line number, and Type the equation using the various operators. Good Practice • Saving common filters as form sets allows you to re-use them throughout your project.

MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) Notes: Lesson 1 – Introducing the Vizex Graphic Environment Duration: 30 minutes Vizex is MICROMINE’s main graphic display environment, and opens by default when you open MICROMINE. Using Vizex, you can load as many objects as your computer, common sense, and clarity will allow. You can display all MICROMINE object types, including downhole information, pit designs, block models, and wireframes. Editing functions include a rich suite of tools for snapping, smoothing, weeding, gradients, curves, draping, and wireframing. The Vizex environment also supports seamless transitions between 2D and 3D views. After this lesson you’ll be able to: • Work with the Vizex user interface; • Manage Form Set and Display objects; • Change the view orientation using one the standard views; • Manipulate the view by using the zoom and pan tools. Introducing Vizex What is Vizex? The Visual Explorer (Vizex) graphical interface provides a fully interactive display environment for all MICROMINE object types. You use the Object Manager to combine and display multiple sets of form set objects to form a layered display. Multiple datasets can be viewed and edited interactively using the Vizex Graphic Editor . To speed up graphical editing, display layers can be easily turned on and off using the Display Pane of the Object Manager. Multiple datasets can be viewed simultaneously in plan and section view by selecting the Window | New Window menu option. Copyright © Micromine 2004 Page 1
- 93. MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) Notes: Starting Vizex Vizex will open by default whenever you start MICROMINE. If Vizex is not open, it can be opened with any of the following methods; • Click the Vizex toolbar button; • Load any object or saved view from the Form Sets Pane; or • Load any object or saved view by selecting any option from the Display | Vizex menu Exercise 1.1: Load a previously saved view In this exercise you’ll start Vizex and re-display a previously saved view. 1. Ensure Vizex is open. If Vizex is not open, open it by clicking on the Vizex Toolbar button. 2. Once the Vizex environment is open, open the Saved Views node by single-clicking the small plus [+] icon to its left. This node is located at the top left of your screen, immediately under the menu and toolbar. Copyright © Micromine 2004 Page 2
- 94. MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) Notes: 3. Double-click the Lesson One object to open it. 4. Vizex will load a number of different display objects into the window and then change the window extents to match the saved view. The User Interface The Vizex environment consists of three primary areas: the Graphic Display , which occupies the bulk of the screen; and the Form Sets and Display/Objec Manager window panes, which by default dock to the left hand side of the screen. If desired, you can dock the Form Sets and Display panes to the left, right, top or bottom of the Graphic Display, or move them to an undocked position floating over the graphic display. There is an auto hide icon on the Form Sets and Object Manager window which can be used to maximise the Graphic Display area and hide these windows when they are not in use. t You can toggle the panes on and off by clicking the Form Sets and Object Manager icons on the main toolbar. Alternatively, you can open these panes by selecting View | Object Manager or View | Form Sets from the menu. To close the panes, click the Close button at the top right-hand corner of each pane. The View toolbar at the top of the screen provides a variety of tools for selecting and manipulating data, and manipulating the view. Depending on the tools you’ve selected, Vizex may also display additional toolbars. Form Sets Pane You use the Form Sets pane to select the Form Set Objects you want to include in the Graphic Display. Before you define a Form Set Object as a Display Object , you can modify form set properties to control the way data will appear in the display. To create a Form Set Object, select an option from the Display | Vizex menu. Alternatively, you can double-click an object type under the Vizex Folder to create a new Form Set Object. If there are no objects displayed under the Vizex Folder in the Form Sets Pane, simply click on the plus [+] icon to it’s left to expand the options. Copyright © Micromine 2004 Page 3

- 96. MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) Display Pane Notes: You use the Display pane to manage the currently loaded objects. The Display pane lists the current Display Objects . You can rearrange the drawing order of these objects by dragging and dropping them with the mouse. Vizex draws objects from the bottom of the Display pane upwards. You can adjust your display by simply dragging objects into the desired display order. Objects displayed in the Vizex Graphic display window are listed under the Vizex icon in the display panel. If you have a 3D view open in 3D viewer at the same time, these will be listed under the 3D viewer icon in the display pane. When displaying multiple data layers it’s sometimes useful to temporarily turn off or hide a layer without removing it permanently from the display. This gives you a better view of the objects you’re interested in. To hide a Display Object or layer, simply uncheck the checkbox alongside the name of the object. To redisplay an object simply check the checkbox alongside the name of the object. The object is re-drawn in the Graphic Display. Whether the object is visible or not will depend on the current display limits. In comparison, when you delete an object (by clicking it and pressing the Del key), it’s removed from the Graphic Display and is permanently deleted from the Display pane. Note that the form set you used to load the display object is still available for selection in the Form Sets pane. Exercise 1.2: Use the Display pane to manage the display This exercise will show you how to manage the graphic display by accessing objects in the Display pane. 1. Click the check box next to the Aeromag image display object to set it. 2. Vizex will display the image, but it obscures the remaining objects in the display. Copyright © Micromine 2004 Page 5
- 97. MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) 3. Click the Aeromag image display object’s name or icon in the Display pane, and drag it to the bottom of the list. When you release the mouse, Vizex will re-draw the display with the magnetic image at the bottom. Notes: 4. You’ll notice that the Aeromag image display object now has a blue highlight on it, which indicates it’s selected. Press the Del key on the keyboard to delete it. Alternatively, you can right-click and choose Remove from the popup menu. Manipulating the View The Vizex environment is fully interactive, providing you with a suite of tools that allow you to easily view and manipulate your data. Many of these tools are dedicated towards manipulating the view itself, which is the focus of the next few topics. The Standard Views By default, Vizex creates new views in Plan orientation, which is one of six standard orthogonal views. You can easily switch between these view orientations by clicking the Standard View buttons on the toolbar. The shaded side of each cube indicates the viewing direction. If you hover the mouse over a button, Vizex will display a ‘tool tip’ indicating the purpose of that button. If required, you can take additional control over the view by using the Display Limits dialog, which you can access by clicking the Display Limits toolbar button, or by choosing View | Viewpoint | Edit from the menu. The display limits dialog has three tabs: Orthogonal , which allows you to make sections orthogonal to your coordinate grid, Transform , which allows you to make sections at an angle to your grid, and 3D View , which allows you to view your objects from different positions and angles by rotating and moving the camera. You can also define the window clipping values on this dialog. The settings that Vizex applies will depend on which tab is active when you click the OK button. We’ll look at this dialog in more detail in Lesson 3. When you are using the standard views, an editable input box can be used to quickly change the section you are viewing. This is located on the View Toolbar next to the standard view buttons. Once a section has been entered into this box, it can be quickly accessed using the drop down menu.

- 98. MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) Notes: Vizex also provides numerous tools for zooming and panning, including a generous zoom undo and redo memory. Exercise 1.3: Use the standard views 1. Experiment with the effects of the standard view buttons by clicking each toolbar button in turn. Note how sectional views like Looking North or Looking West currently don’t apply any clipping to the data, but simply project the data against the requested plane. You’ll learn how to correctly display cross sections in Lesson 3. 2. When you’ve finished experimenting with the standard views, return to the Plan view orientation. 3. Click the Pan tool and drag the mouse in the display. Note how the view dynamically pans. 4. Click the Zoom tool and drag a medium sized rectangle in the middle of the screen. Vizex zooms to the extents of that rectangle. 5. Click the Undo Zoom button to return to the previous extents. 6. Click the Pan tool and hold the Ctrl key. Now drag the mouse vertically in the Graphic Display. The dynamic zoom is an alternative to the standard Zoom tool. 7. With the view zoomed-in, click on the Simple drillhole trace object in the Display pane to select it. 8. Now right-click and choose View Selection from the pop-up menu. The view will adjust to fit the drillhole trace display into the screen. Note how the drillholes are surrounded by a dashed rectangle, which indicates the layer is selected.

- 99. MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) Notes: Grid Settings Vizex gives you very good control over the way your coordinate grid is displayed. To change the grid settings , select View | Grid Settings… from the menu, click the Grid Settings toolbar button, or right click in the display and select Grid Settings… from the pop-up menu. A useful feature of the Grid Settings dialog is the Auto spacing option, which automatically calculates the appropriate grid spacing to keep between 5 and 10 grid lines in the display. Grid settings can be saved as form sets, so you can save and recall spec ific grid settings asrequired. Exercise 1.4: Set up a 100m coordinate grid 1. Select View | Grid Settings from the menu. 2. Set the Grid type to FULL . 3. Set the three Spacing responses to 100 ensuring auto spacing is unticked. 4. Select (check) both the Top/Right and Bottom/Left label options for all three axes. 5. Select Vertical text? for the East axis. 6. Set the Label annotations to mE , mN , mRL . 7. Click OK to accept the settings. Your display should look like the following illustration. 8. Once you’re satisfied with the result, select Edit | Remove All to clean up the display in preparation for the next exercise. Copyright © Micromine 2004 Page 8

- 103. MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) Notes: Lesson 2 – Creating a Preliminary Display Duration: 60 minutes Once you’ve loaded the various data sets into a project, the next step is to create a preliminary display. The tasks in this lesson demonstrate how to create a multi-layer display in which all data sets in the project can be shown. After this lesson you’ll be able to: • Display surface geochemistry as shapes. The size of the shapes will vary according to the values of the underlying data; • Display a tenement outline; • Display an aerial photograph of the area; • Create a colour set and save it as a form set; • Create and display a contour grid file; • Combine these displays into a single coherent view of the area of interest. Making a Multi‐layered Display The ability to display all data sets simultaneously helps you to form an overall idea of the area of interest. Vizex can display multiple layers of information including binary files such as raster images and contour grid files. Vizex can also display drillholes in plan, section, and 3D, although this functionality won’t be introduced until Lesson 3. Copyright © Micromine 2004 Page 12
- 104. MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) Loading Geochemical Samples as Points Notes: Most surface geochemistry data can be displayed as points. Because the underlying data can be used to control the size of the point markers, it’s an ideal method for graphically presenting information, much the same as you would when using a GIS. You control the size of the points in two ways: By applying a scaling factor or by specifying a series of ranges and a radius for each. With the first method you can apply a minimum and maximum radius and scale the points smoothly between those limits. With the range method, the points are limited to the sizes you specify. You can also apply a natural-log transform, which is applied before the scaling factor or range calculation. Exercise 2.1: Display the geochemical data as points Let’s look at adding points to the display: 1. In the Form Sets pane, double-click the Points object type. Alternatively, you can choose Load | Points from the menu. 2. The Load Points dialog consists of three tabs. Fill out the Load Points tab as shown: Prompt Setting File: NVG_GCM Type: DATA East field: EAST_GRID North field: NORTH_GRID Z field: RL Vizex dialogs are just like all other MICROMINE dialogs, with one exception: Complexdialogsare displayed asa series of tabs rather than one large dialog. Copyright © Micromine 2004 Page 13
- 105. MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) Notes:3. Now switch to and complete the Symbols tab as below: Prompt Setting Shape: SYMBOL Default symbol: (Filled triangle – select by double- clicking the symbol box) Display field: AU1 Font: Tahoma, 8 point regular (double- click the AaBbYyZz text) Position: Diagonal top right (select by double-clicking the position box) 4. This is enough to create a preliminary display, so click OK to load the points. Your display should look like the following diagram. Vizex did several things when you clicked OK: Firstly, as expected, the new data appeared in the Graphic Display. And secondly, a new display object appeared in the Display pane. Creating a Numeric Colour Set The current display is functional but not very informative. One way to improve the visual effectiveness of the display is by adding some colour. You add colour to any MICROMINE display by creating a Colour Set . Colour sets make it easy to differentiate between values, regions and other objects in the display. The tools you use to create colour sets in MICROMINE are particularly powerful. Because colour sets can be saved as form sets you’re Copyright © Micromine 2004 Page 14
- 106. MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) able to use them anywhere in a project and can even export them to other projects. This promotes consistency and saves time. Notes: There are two types of colour sets: numeric and text. You use numeric colour sets with numeric data and text colour sets with character data. In this case you’ll create a numeric colour set. Exercise 2.2: Create a numeric colour set To create the colour set: 1. Double-click the NVG_GCM.DAT object on the Display pane to change the properties of the points. Alternatively, you can right-click the display object and choose Properties… from the pop-up menu. To change the properties of an object that’s already in the display, you should access it from either the Display pane or the Graphic Display. In comparison, you should only use the objec tsin the Form Sets pane to add n e w items to the display. 2. Click the Symbols tab to activate it. 3. At the bottom of the Symbols tab, double-click the Colour field response and select AU1 from the field list that appears. 4. Right-click the Colour set response. The Edit Colour Sets (Numeric) dialog will appear. (If there are already values in this dialog, click the Clear Table button at the top-left corner to empty it.) 5. Click the Assign button. The source File and Value field responses should be filled out automatically in the Assign dialog. 6. Set Calculate mode to RANGES and set the number of ranges to 5 . 7. Click OK . Five equal numeric ranges will be calculated for the colour set. There’s also provision for values above and below these ranges. The next step is to allocate a colour to each range. To do this: 1. Double-click the colour beside the first (top) entry in the table of ranges. 2. Select a dark blue colour and click OK . Copyright © Micromine 2004 Page 15
- 107. MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) 3. Move to the last completed row in the table and do the same, this time selecting red. Notes: 4. Return to the first row and check the Ramp checkbox beside it. 5. Do the same for the last row. 6. Click the Colour Ramp button at the right of the dialog. The intermediate ranges will receive colours in between red and blue. MICROMINE also provides a variety of standard colour palettes, plus you can easily choose your own colours as desired. Additionally, there are three alternative methods for calculating the numeric values: RA NG ES , PERC ENTILE , and STA TISTIC A L. Finally you must save the colours in a form set. To do this: 1. Click the Forms button (while still in the Colour sets dialog). 2. Click Save As. 3. Enter Soil geochem Au1 as the colour set Title. There’s no need to change the number of the colour set; MICROMINE automatically finds the next available number. 4. Click OK . 5. Return to the Points dialog by clicking OK . The number allocated to the colour set will appear in the Colour set response. 6. Click OK on the Load Points dialog to apply the changes and return to Vizex. The process of creating a form set containing colours is exactly the same as you’d use to create any form set. Form sets store the contents of dialog forms, and are a key feature in MICROMINE because they enable you to re-use the same settings on different data sets. Scaling the Points In addition to colouring the point symbols, we can further increase the visual effectiveness of our geochemical display by scaling each symbol according to its value. Copyright © Micromine 2004 Page 16
- 108. MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) Vizex uses two different scaling methods: Factor and Ranges . In this exercise you’ll use the Factor method, which scales each symbol based on the values in the chosen Scaling field. If required, you can also specify minimum and maximum radii to prevent the shapes becoming too small or too large. Notes: When you use this method, the function reads the value in the Scaling field for each point and performs the following calculations: • If it’s less than or equal to the Base value (a cut-off), the point is ignored. • Otherwise, the difference between the value in the Scaling field and the Base value is multiplied by the Scaling factor to determine the radius of the shape. • If the radius is less than the Minimum radius, then the Minimum radius is applied. • If the radius is greater than the Maximum radius, then the Maximum radius is applied. • When the Natural log transform is enabled, the log is taken after the Base value is subtracted from the value in the Scaling field. Exercise 2.3: Vary the symbol size according to value 1. Double-click the NVG_GCM.DAT object on the Display pane (Or, right-click it and choose Properties… from the pop-up menu.) 2. Click the Scaling tab to activate it. 3. Set up the Scaling tab as shown here: Prompt Setting Scale symbols? Set Scaling field: AU1 Natural log transform? Set Method: Factor 4. Finally, click the Factor Values… button and fill out the following prompts: Prompt Setting Base value: 3 Scaling factor: 0.5 Minimum radius: 1 Max radius: 100 Copyright © Micromine 2004 Page 17
- 109. MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) Notes: Now that the Points display is completed, it makes sense to save it as a form set for later re-use. To do this, follow these steps: 5. Click the Forms button (on the Load Points dialog) to display the Forms dialog, and then click Save As. 6. Type in the title Surface geochem and click OK to return to the Load Points dialog. Observe how the title now appears at the top of the dialog. 7. Click OK on the Load Points dialog to update the display, which should now resemble the following diagram. If you inspect the Display pane, you’ll see that the name of the display object has changed from NVG_GCM.DAT to Surface geochem . Additionally, if you check the Form Sets pane, you’ll notice that the Sur ace geochem object also appears as an item under the Points form set node. f At any time, if you click the plus [+] icon next to a form set node you can expand the tree to display the saved form sets listed underneath it. However, your settings will only appear if you’ve saved them asa form set. Loading a Tenement Outline MICROMINE uses outlines to represent closed shapes, such as geological units, ore grade outlines, or tenement boundaries. Outline files support fill patterns and colours for presentation, and can be labelled with a variety of attributes. In this exercise, you’ll load a simple outline file containing a tenement boundary. Copyright © Micromine 2004 Page 18
- 110. MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) Exercise 2.4: Load a tenement outline Notes: To load the outline: 1. On the Form Sets pane, double-click the Outlines object type to display the Load Outlines dialog. Or, if you’d prefer, you can select Load | Outlines from the menu. 2. Double-click in the Outline file response and choose the TENOUT file from the list. 3. Set the Orientation to PLAN . 4. Set the Name and clear the Fill options in the Display Options group. 5. Double-click the font preview box and set the font to Tahoma, 14 point regular . 6. Click the Forms button, followed by Save As on the Forms dialog. Type in the title Tenement boundary and click OK . 7. Click OK on the Load Outlines dialog to return to Vizex and update your display. 8. To view the entire tenement boundary, right-click the Tenement boundary display object in the Display pane and select View Selection from the popup menu. Displaying an Aerial Photograph of the Area The next layer you’ll add to the Vizex display is an aerial photograph. MICROMINE supports a wide range of raster images, which are files made up of a series of coloured pixels. If you know the scale of the photograph and the resolution (number of pixels per inch) at which it was scanned, you can calculate the real-world dimension of each pixel. If you also know the coordinates of two features on the image, or the coordinates of the pixel in the top left corner of the image, you can georeference it to the other datasets. There are two other ways to georeference an image: • Interactively. Using this technique you select two points in the image and enter the coordinates of each. Vizex will then use these to calculate the georeferencing information. • From existing data. You can load ArcView, MapInfo, ESRI, ER Mapper, or GeoTIFF files that contain the georeferencing information. Copyright © Micromine 2004 Page 19
- 111. MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) Notes: In the next exercise, you’ll use coordinates that are supplied with the image. Exercise 2.5: Display an aerial photograph To display an image: 1. On the Form Sets tab, double-click the Image object type to display the Load Image dialog. Alternatively, you can also select Load | Image from the menu. Ignore the values already in the Image dialog; they’re simply left over from Lesson 1. 2. Click the browse […] button next to the File response and double-click the Import folder. Select the MMI_IMAGE.ECW file. MICROMINE will automatically search for and load the georeferencing header information. 3. Set the Image intensity to 400 . This will stop the image overpowering the other information in the display. 4. Set the Orientation to PLAN . 5. Set the Section to 1600 . This will set the image to the approximate RL of the surface topography in that area. 6. Click Forms followed by Save As and save the settings as a form set called Air photo . Click OK on the Load Image dialog to return to Vizex. 7. You’ll see that the image obscures all of the other data in the display. To change the display order, drag the Air photo object (in the Display pane) to the bottom of the list. When you release it, the display will refresh with the photo beneath the other objects. MICROMINE supports most common image and georeferencing formats. If you have an image in an unsupported format, use a graphics conversion program to convert the file into a compatible format. In addition, if you want to use a large image, it’s best to convert your image into the highly compressed ER Mapper ECW format. Copyright © Micromine 2004 Page 20
- 112. MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) Notes: Gridding the Geochemical Data Another way of displaying the geochemical data is to generate an interpolated contour grid display. You can use the grid file created by the Display | Contours | Generate Grid function as input to Vizex. Exercise 2.6: Create an interpolated grid of the geochemical data To set up the contour grid display: 1. Select Display | Contours | Generate Grid from the main menu. 2. Enter NVG_GCM in the File response. 3. Enter AU1 in the Grid field response. 4. Click Grid Limits… and check that the X Field is set to EAST_GRID and the Y Field is set to NORTH_GRID . Double-click the minimum and maximum values to set them if required. 5. Enter 5 for X block size and 5 for Y block size. Notice how MICROMINE automatically calculates the number of blocks. 6. Activate the Preview mode option and click More…. Set the Input data colour to dark blue and the Nearest points colour to bright red. 7. Set the Gridding Method to INVDISTPOW . 8. Click the Data Search… button and set the Search radius to 75 . 9. Set the Duplicate points option to AVERAGE . 10. Enter NVG_AU1_CONTOUR in the Output Grid file response. 11. Click OK to run the function. The grid file will be created after a few moments. Exit the Gridding function once it’s done. Copyright © Micromine 2004 Page 21

MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) Exercise 2.7: Add the grid to the display Notes: It makes sense to use a modified version of the colour set you created for the Points display. 1. Double-click the Grid File object type on the Form Sets pane. 2. Double click the Grid file response and choose NVG_AU1_CONTOUR . 3. Set the Orientation to PLAN . 4. Double-click in colour Set number, and select Grid geochem Au1 from the list. Click Select to open the form set. The grid file actually coversthe entire area, but by “nulling” out the low values, we’ve produced a display grid that only highlights the anomalies. 5. Click Forms then Save As and save the settings as a form set called MMI Soils Geochem Au1 . Click OK on the Grid File dialog to return to Vizex. Completing the Picture Now that you’ve defined the final item for your display, you can reload your previously saved form sets at any time you wish to use them. If you inspect the Form Sets pane, you’ll notice that the Grid File, Outlines, Points and Image object types all have a new plus [+] icon next to them. To remove the existing display items: 6. Select Edit | Remove All from the main menu. To reconstruct your display: 7. Click the plus [+] icons next to the Outlines, Points, Image and Grid object types to display the form set objects that you previously created. 8. Double-click on each of those form sets to load them into Vizex and rapidly re-construct the display. 9. If you need to change the display order, drag the objects in the Display pane to change their order to your satisfaction. Your display should look something like the following picture.

- 117. MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) Notes:Good Practice Saving Vizex display layers as Form Sets allows you to very quickly reconstruct a comprehensive display, without re-defining each display object. Because Form Sets are so easy to create in Vizex, it’s possible to create multiple versions of the same information. For example, you could create a Strings object for topographic contours coloured by elevation, and another of the same contours coloured according to whether they’re index or intermediate contours.

- 118. MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) Notes: Lesson 3 – Working with Drillholes Duration: 90 minutes Lessons 1 and 2 have focussed on the basics of Vizex, and have introduced you to various object types. Drillholes are an integral part of Vizex, and this lesson will teach you to manage and display drillhole data. Vizex supports numerous down-the-hole object types, such as Values (labels), Hatch patterns, Graphs, and Events. You construct your drillhole display simply by adding as many of these objects as required. When you use these in conjunction with other object types, such as sectional geophysical images, DTM’s of topography or oxidation surface boundaries, and outlines of geological interpretations, you can produce a rich and informative drillhole display. After this lesson you’ll be able to: • Construct and manage a Drillhole Database; • Display drillhole traces and their associated down-the-hole data; • Set up orthogonal and transform cross sections; • View the drillhole data in 3D; • Create a text colour set and a text hatch set. Introduction Vizex uses a highly efficient method for managing drillhole data, called the Drillhole Database . Using the Drillhole Database, you can easily create and manage all drilling data that’s relevant to a particular project. Once you’ve created a Drillhole Database, you can use the power of Vizex to display your downhole information in plan; in both orthogonal and transform (angled) drillhole sections; and in 3D. Vizex supports numerous types of downhole data, such as: • Drillhole traces: Displayed as a simple line, or colour coded according to a table field; • Values (labels): Positioned either side of the drillhole traces; • Hatch patterns. These allow you to create symbolically filled displays; • Events. Downhole data that occurs at an At rather than between a From and To; • Graphs: Various presentation techniques for downhole data such as recovery, magnetic susceptibility, etc. Copyright © Micromine 2004 Page 27
- 119. MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) This lesson will introduce you to the drillhole database and teach you how to create and manage your drilling data. You’ll also learn to create and display a variety of downhole information. Notes: The Drillhole Database Creating a New Database You create a drillhole database from either the main menu (Dhole | Database | Create), or from Vizex. To create a new Drillhole Database within Vizex, double-click the Drillhole Trace form set object, then right-click the database response and select New Database from the pop-up menu. To set up a Drillhole Database, you start by specifying a Collar and Downhole Survey file. Once these are set, you add any Event or Interval files directly to the database. Drillhole Accuracy Although most drillholes describe a curved line (known as the trace ), MICROMINE approximates the trace as a series of straight-line segments. When you construct a Drillhole Database, Vizex automatically varies the Trace Interval from hole-to-hole to keep the calculated drillhole within a predefined distance of the true drillhole location. MICROMINE does this by specifying a cylindrical threshold around the true location of the drillhole trace, and then ensuring that the calculated trace remains within that cylinder. The radius of this cylinder is 5cm. Copyright © Micromine 2004 Page 28

So, if only part of a drillhole falls within the data corridor, only that part will be visible and the remainder will be excluded. Setting up a Cross Section There are several ways you can set up a cross section, but one possible procedure might be: • For an orthogonal section, activate the Display Limits dialog and click the desired View Type, for example Looking North . • Enter the desired section coordinate into the Section response. • Activate the Clip to window? option and enter values for Window Towards and Window Away. • For a transform section, first select the Section toolbar button and define your section by dragging in a plan view. • When the section appears, activate the Display Limits dialog and set the desired Clip to window values. Once the section is displayed, you can toggle the clipping by clicking the Enable Clipping toolbar button. While clipping is enabled, you can use the Previous Section and Next Section buttons to browse forward or backward through your data. The step size is defined by the sum of Window Towards and Window Away. Clipping Off Clipping On You can freely switch between different views once you’ve defined the section settings. For example, you might wish to return to a plan view so you can drag another transform section. Or, you might want to change from a cross section Copyright © Micromine 2004 Page 38

Vizex remembers your clipping settings and applies them where appropriate. Notes: In any Orthogonal Section, the Elevation/Section value is displayed in an editable input box on the view toolbar next to the standard viewing buttons. A section value can be entered in this box, and when you wish to return to this section or elevation, it can be re-selected from the dropdown menu. Exercise 3.3: Display data in cross section In this lesson, you’ll set up a standard looking north cross section, followed by a transform section. First, let’s set up the section display: 1. Click the plus [+] icon next to the Wireframes object (in the Form Sets pane) to display the list of previously saved form sets, and double click the DTM 2D slice mode object to open it. 2. Click the Display Limits toolbar button. 3. Change the View Type to Looking North . 4. Set the Section Northing to 15900 . 5. Activate Clip to window? and set both Away and Towards to 15 . 6. Click OK to make the changes. Vizex displays the section. 7. Click the Next Section and Previous Section buttons to browse through the data. The status bar displays the current 3D cursor coordinate (which incorporates the section number) at the lower right corner of the screen. Now, let’s set up a transform section: 1. Click the Plan button to return to a standard plan view. 2. Right-click in the Graphic Display and choose View All from the pop-up menu. 3. Click the Section toolbar button and drag an oblique section at an angle to the drillholes. Note how Vizex displays the section extents as you drag the mouse. When you release the mouse, Vizex displays the transform section. Copyright © Micromine 2004 Page 39

MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) Creating a Text Colour Set Notes: So far, we’ve created a numeric colour set, which has assigned groups of numeric ranges to specific colours. We can use a similar technique to create a text colour set. Text colour sets work with unique character codes instead of numeric ranges. When you use the Assign button, MICROMINE finds all unique values in the selected field. To simplify your colour set, you can group similar values in one of two ways: Auto Group, which simply groups the codes by the first n characters, or Manual grouping, where you decide what codes will be gathered together. Auto grouping is best for hierarchical codes, such as standard Geological Survey codes, where there’s a distinct hierarchy in the code structure. Non- hierarchical codes are best handled using manual grouping. You’ll use manual grouping in the following exercise. Exercise 3.7: Create a text colour set 1. Double-click the Lithology labels (black) object in the Display pane and activate the Value Coordinates tab. 2. Right-click the Colour set response to edit the colour set. The Edit Colour Sets (Text) dialog will appear. If there are already values in this dialog, click the Clear Table button at the top left of the dialog to remove them. 3. Click the Assign button at the right of this dialog. 4. MICROMINE identifies the file and field we’re working on, so just click OK on the Assign dialog when it appears. Grouping and assigning codes 5. A second Assign dialog will appear, containing two columns. The Found column contains all unique codes in the file, and the Text column will contain our newly created groups. Copyright © Micromine 2004 Page 44
- 136. MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) 6. Highlight the ANDS code in the Found column and, ensuring that Group? is turned off , click the right arrow button. The code will be moved to the Text column. Notes: 7. Turn on the Group option, highlight the DACT code, and click the right arrow button a second time. Observe how the two codes now appear on a single line in the Text column. 8. Turn Group off and move the FAUL code. Now turn Group back on and move the FBX code. Again, observe how they appear on the same line in the Text column. 9. Finally, turn Group off and click the double right arrow to move the remaining codes (NC , SED , and VEIN ) as separate entries. Your Assign dialog should look like this: 10. Click OK to close the Assign dialog. Your newly created groups are transferred to the Colour Sets dialog. Copyright © Micromine 2004 Page 45
- 137. MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) Allocating colours and saving the colour set Notes: 1. Double-click each colour and set it to a colour that you feel is appropriate for each code group. If you’d like, you can also type in a more descriptive Label for each. Once you’re finished, your dialog should resemble the following: 2. Now, click Forms, followed by Save As, and save the colour set as Basic lithology colours . 3. Once you’ve saved the form set, click OK to close the Colour Sets dialog and return to Vizex. Note how your new form set number appears in the Colour set response. Saving a new Drillhole Value form set Let’s save these settings as an alternative form set to the black labels we created earlier. 1. On the Drillhole Value dialog, click Forms, followed by Save As. 2. In the Save Current Values… dialog, click the New button to allocate a new from set number. If this button is disabled, Vizex has already done this for you. 3. Set the Title to Lithology Labels (coloured) and click OK . 4. Finally, click OK on the Drillhole Value dialog to accept the changes. You don’t have to explicitly save the settings as a new form set, since Vizex will automatically overwrite the old settings when you click OK. However, it’s a good habit to establish, since you may not w a n t to overwrite the old settings! Creating a Hatch Display The drillhole display is becoming informative, but the very skinny drillhole traces are still somewhat unsatisfactory. We can improve the visual appearance of the drillholes by placing a hatch display along the drillhole trace. Hatch sets allow you to place a fill pattern into any enclosed region. There are three main applications for hatch sets: • Downhole hatches (lithology, oxide, etc.); • Downhole graphs (assay, recovery, etc.); Copyright © Micromine 2004 Page 46
- 138. MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) • Polygonal interpretations. Notes: MICROMINE ships with a large number of hatch patterns. However, if you require additional patterns, you can use any TrueType font. If you’re a GIS user, this means you can use your favourite ArcView™ or MapInfo™ hatch patterns right within MICROMINE. When you set up a hatch set, you can independently control the pattern, foreground and background colours, symbol size, and outline of each pattern. Additionally, many MICROMINE functions allow you to further control the allocation of foreground and background colours. Exercise 3.8: Add a hatch pattern to the display In this exercise, you’ll add a geological hatch pattern to each drillhole trace. Setting up the fill patterns 1. Double-click the Drillhole Hatch Form Set Object and make sure the Hatch Coordinates tab is active. 2. Double-click the Database response and choose your TRAINING database. 3. Double-click the Interval file response and choose NVG_LITH_NO_ERR.DAT . 4. Activate the Hatch Display tab and set the Use hatch field? option. 5. Set the Hatch field to LITH . 6. Right-click the Hatch set response to display the Edit Hatch Set (Text) dialog. 7. Click the Assign button. 8. At this point, the Assign procedure is the same as Exercise 3.7, so if required you can refer back to those steps for guidance. Copyright © Micromine 2004 Page 47
- 139. MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) 9. Once you’ve set up the codes, click OK to return to the Edit Hatch Set dialog. Notes: 10. Double-click each default hatch pattern to display the Fill Pattern dialog. As before, create a fill pattern that you think is appropriate for each code group. Experiment with foreground, background, and border colours in addition to the patterns themselves. Your dialog should resemble this: 11. Once you’re done, click Forms, followed by Save As, and save the hatch set as Basic lithology . Click OK to return to Vizex. Choosing a size and position for the hatch display If you display the Side list, you’ll see that Vizex only provides options for LEFT and RIGHT . What if you’d like to centre the hatch? Fortunately, there is an easy way. 1. Leave the Side set to LEFT . 2. Set Offset distance to –2 , and Hatch width to 4 . 3. Set the Border to 4 SIDES . 4. Click Forms, then Save As, and save the hatch display as Drillhole lithology . Click OK to return to Vizex. Your display should look like the following diagram: Copyright © Micromine 2004 Page 48
- 140. MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) Notes: Hatch widths are always measured in real-world units. So, our hatch pattern is literally four metres wide. Plotting this at 1:1,000- scale would result in a hatch width of 4mm on the paper. Offsetting the value displays If you zoom in on a drillhole, you’ll notice an unfortunate side effect produced by the hatch display: It overlaps the value labels. In order to produce an elegant display, we need to offset the two drillhole value displays so that they aren’t overlapped by the hatch pattern. Here’s how you do it: 1. Double-click the Statistical assay labels Display object and activate the Value Display tab. 2. Set the Offset distance in both the Labels and Ticks groups to 2 , then click OK . Vizex will automatically save the modified form set and adjust the display. 3. Repeat Steps 1 and 2 for the Lithology labels (coloured) Display object. 4. Now zoom in on a drillhole and observe how the value ticks stop exactly at the edge of the hatch display. It’s as easy as that! 5. Select the Drillhole lithology object in the Display pane, right-click and choose View Selection from the popup menu. Copyright © Micromine 2004 Page 49

MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) Creating a Plot File Notes: You’ll now create a plot file of the cross section display, to be later used in the Plotting exercises in conjunction with your earlier plot. Exercise 3.9: Create a plot file To create a plot file: 1. Click the Plot toolbar button. Or, select Plot | Generate from the menu. 2. Set the Plot file name to Section15900 . Don’t change any of the other responses at this stage. 3. Click OK to make the plot file. 4. Finally, select Edit | Remove All from the menu to clean up the display. The lessons and exercises we’ve covered so far have all been leading to Lesson 5, where we’ll begin to interpret our data. Copyright © Micromine 2004 Page 50
- 142. MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) Notes: Lesson Three Summary This lesson has taught you to manage and display drillhole data. You’ve worked with various items of downhole data, such as Values and Hatch patterns. Additionally, you’ve seen how to view data in cross section and 3D, and how to set up text colour and hatch sets. To create a drillhole database: Select Dhole | Database | New from the main menu, or Double-click a Drillhole object in Vizex, then Right-click the Database response and choose New from the popup menu, finally Enter the desired file names. To refresh a database: Select Dhole | Database | Refresh from the main menu, or Right-click the Database response on a Vizex dialog and choose Refresh from the popup menu. To display a Drillhole object: Double-click the desired object type in the Form Sets pane, then Select the Database and appropriate files, and Set up the display parameters as required. To display a cross-section: Open the Display Limits dialog, then Choose the View Type and enter the Section number, then Set the Window Toward and Away values. To display a transform section: From a Plan view, use the Section tool to drag an interactive section, then If required, open the Display Limits dialog and set the clipping values.

- 144. MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) Notes: Lesson 4 – The Graphic Editor Duration: 90 minutes After this lesson you’ll be able to: • Activate the Graphic Editor and create a new file; • Move and copy a string; • Insert and delete points; • Snap points and use a snappable layer; • Create a basic wireframe. Introduction The Graphic Editor provides you with a rich suite of tools for editing string and outline files. Using these tools, you can smooth and weed strings, define gradients and curves, drape a string onto a wireframe, and snap to any other object in the display. You can also easily insert, move, and delete points, as well as move, copy and delete entire strings. The User Interface You access the Graphic Editor functions through the Graphic Editor Toolbar , which only becomes visible when the editor is active. In addition to the toolbar, the Graphic Editor provides numerous context editing modes, where the exact function depends on the type of feature under the mouse cursor. There’s also a right-click context menu that provides additional tools. Activating the Graphic Editor You can only activate the Graphic Editor when you’ve selected an editable display object; in other words a string file or outline file. If you’ve selected one of these objects, either in the Display Pane or in the Graphic Display , the Graphic Editor button on the main toolbar will be enabled. If nothing is selected, or a non-editable object is selected, the Graphic Editor button will be disabled. When you click the Graphic Editor button, the String Editor Toolbar appears below the main toolbar. It’s a dockable bar, so you can position against any edge of your screen, or have it floating over the Graphic Display. This toolbar can also be turned off by right clicking anywhere in the toolbar region and unselecting the Edit Strings toolbar. To turn off the Graphic Editor, simply click the Graphic Editor button a second time. If you’ve left any unsaved edits, Vizex will prompt you to save them before shutting down the editor. Copyright © Micromine 2004 Page 53
- 145. MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) Exercise 4.1: Activate the Graphic Editor Notes: In this exercise, you’ll load several objects that you’d use for a sectional drillhole interpretation and turn on the graphic editor. 1. Open the Saved Views node in the Form Sets pane by clicking the small plus [+] icon next to it. 2. Double-click the Lesson Four object to load it. Vizex will load four display objects, but only one, an outline file containing a series of rock unit interpretations, will be turned on. 3. Click on the Sectional geology interp object in the Display pane to select it. Vizex will do two things: It will place a selection rectangle around the outlines in the graphic display and it will enable the Graphic Editor toolbar button. 4. Click the Graphic Editor button to activate the Graphic Editor. A new toolbar will appear. Elements of the Graphic Editor The Graphic Editor’s primary interface is the Graphic Editor Toolbar: Using this toolbar, you can access these main editing functions, which are listed in the order that they appear in the toolbar: • New String: Begin digitising a new string. • Snap: Toggle snapping on and off or select snap to point, snap to line, or snap to grid. • Insert Points: Toggle insert on and off. • Between tool: Draw a string by inserting points between two selected points. • Follow tool: Allows you to create new strings following an existing string, or to create copies of a string, or section of a string. • Insert Intersection: Insert a point at the intersection of two existing strings. • Extend String: To append points to one end of a string. • Close String: To close the selected string – the start and end point of the string will be connected by a new segment. • Expand String: Expand a string based on the Expansion distance defined in the Options dialog. • Create DTM: Generate a DTM based on the current string. • Drape on Wireframe: Drape a string onto a wireframe. Copyright © Micromine 2004 Page 54
- 146. MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) • Smooth: Insert a regular spread of points and remove any unnecessary sharp corners in a string. Notes: • Weed String: Reduce the number of points in a string. • Fix Crossover: Detect and resolve crossovers in a string. • Curve: Extend the selected string by appending a curve to the end point. • Gradient: Set the gradient for the selected string. • Bearing/Distance: Append a point at the specified bearing and distance. • Blast Displacement: Used to Calculate Blast displacement of strings and outlines in open pit mining • Use Digitiser: To use a digitiser to create strings. • Setup Digitiser: To setup a digitiser. Editing Features This lesson will explore the various basic editing modes and context menu options that you might use when editing features in the Graphic Display. During the editing process, Vizex will alter the editing function according to whether your mouse cursor is above a point or a string. You can also alter the editing function by pressing either the Shift or Ctrl keys. Vizex gives you visual feedback on the selected editing mode by varying the shape of the mouse cursor. Some editing modes, for example extending, closing, or reversing a string, are accessible from the right-click context menu. Again, the available functionality will vary according to what you’re doing at the time. Before you can use any of these editing modes, you must activate the Select cursor by clicking itstoolbar button. If any other button is selected, the graphic editor toolbar will be disabled. Editing Modes Vizex will alter the exact editing function depending on the context of the mouse (is it over a point or a string segment; is the string already selected?) and whether you’re pressing the Shift or Ctrl keys when you click or drag. To guide you, Vizex also changes the shape of the mouse cursor to indicate the active editing mode. Table 1 summarises the context editing modes. Vizex also provides you with three toolbar buttons that allow you to control the editing process: • New string: Begin digitising a new string. To end a new string, either press Esc or close the string. • Toggle snapping: Toggle snapping mode on and off. Alternatively, you can use the S key as a permanent toggle or Shift as a temporary toggle. The Copyright © Micromine 2004 Page 55
- 147. MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) snapping button will appear different according to the snapping mode you have activated. Snapping mode can be selected from the drop down menu next to the Snapping Button Notes: • Toggle insert: Toggle Insert Point mode on and off. Alternatively, you can use the Shift key as a temporary toggle. Exercise 4.2: Edit features in an outline file Let’s put these functions to work. First we’ll focus on the basic mouse and keyboard combinations: 1. If you haven’t already done so, activate the Select cursor by clicking the Select toolbar button. 2. Click any outline in the display to select it. Vizex will highlight the points that define the feature and you are now ready to edit, it as shown on the following diagram. 3. Position the mouse cursor over a point and drag to move it. 4. Position the mouse cursor over a string segment and drag to move the entire string. 5. Ensure that the snapping mode is set to ‘snap to point’ using the drop down menu next to the snapping button. Hold the Shift key and drag a point to move it. Note how Vizex snaps the point to existing points in the object as you drag. Be sure to hold the Shift key until after you release the mouse button. 6. Hold the Shift key and click on a string segment to insert a point. 7. Hold the Ctrl key and click on a point to delete it. 8. Hold the Ctrl key, position the mouse cursor over a string segment and drag to create a copy of the string. Copyright © Micromine 2004 Page 56

MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) Notes: Table 1: Context editing modes Mouse Over… Key Editing Function (1) Cursor (2) Nothing (New/Extend String mode only ) None Freehand digitise Nothing (New/Extend String mode only ) Shift Digitise (toggles snapping) String None Select ; Move selected string String Ctrl Join ; Copy selected string String Shift Multi-select ; toggles insert Point None Move point in selected string Point Ctrl Delete point from selected string Point Shift Move point in selected string (toggles snapping) (1) Italicised editing functions apply when string is not yet selected; the remaining functions apply to selected strings. (2) Cursors are only shown for editing modes. Selection modes (italicised ) use the standard Windows cursor. Now let’s look at the two toolbar toggle buttons: 9. Click the Snap toolbar button, or alternatively press the S key, to activate Snapping mode, and ensure that snapping mode is set to snap to point. 10. Click on a point and drag to move it. Note how Vizex snaps without you having to hold the Shift key. 11. Change snapping mode to ‘Snap to Line’ using the dropdown menu next to the snapping button. 12. Click on a point and drag to move it. Note how Vizex snaps to lines in the display. 13. Now click the Insert toolbar button to activate Insert mode. 14. Click on a string segment to insert a point. Again, note how you can achieve this without holding the Shift key. The Shift key toggles the Snap and Insert modes irrespective of how they were set beforehand, so you can use it to temporarily reverse either setting whenever required. The exact effect of the Shift key depends on the object (point or string) located under the mouse cursor at the time. Copyright © Micromine 2004 Page 57
- 149. MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) 15. Click the Graphic Editor button to turn off the Graphic Editor. Answer NO when prompted to save your edits. Notes: Creating New Features To create a new feature within a file, you must click the New String toolbar button. Alternatively, you can simply press Enter (with NO selected strings) or right-click and choose New String from the pop-up menu. Vizex will change the mouse cursor into a filled crosshair to indicate the change of mode. You’re now free to add points as required. You can finish a new string in two different ways, depending on whether you want to close it or leave it open. To leave it open , just double-click as you add the last point. Alternatively, you can press the Esc key after adding the last point. Vizex will change the cursor back to the selection pointer to indicate the new string is finished. The easiest way to close a new string is to digitise the last point over the first. Provided you’re reasonably accurate, Vizex will recognise what you’re attempting to do and automatically snap the last point to the first. Closing a string automatically finishes it. You can also right-click and choose Close String from the pop-up menu instead. If you use this method, you should make no attempt to close the last string segment yourself. To set the properties of a new string, just double-click it after it’s been created. Alternatively, you can select the string, then right-click and choose Properties… from the pop-up menu. Finally, you can also use the Properties toolbar button or choose Edit | Properties from the menu. You can also configure Vizex to prompt you for the properties every time you create a new string. To do this, select Options | Vizex from the menu and activate the String Editor tab on the Vizex Options dialog. Simply check the Prompt to edit properties on adding a new string? prompt to enable this option. Snapping and Following Most of your on-screen digitising probably takes place within a framework of existing data. For example, you would typically interpret cross-sections by using existing drillhole information. You can improve the accuracy of your interpretation by snapping to true 3D drillhole intervals whilst digitising. Vizex extends the idea of ‘snapping to drillholes’ to any other object in the display. Copyright © Micromine 2004 Page 58
- 150. MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) Once you’ve started editing an object, simply selecting another object in the Display pane makes it ‘snappable’. So, whilst digitising, say, a rock unit outline, you can snap to a fault surface (represented by a wireframe) to correctly terminate or displace that unit. You could then snap to the drillhole hatch display and continue editing that rock unit outline by making use of the drillhole data. Notes: Snap mode works in two ways: You can either click the mouse to snap single points, or you can drag the mouse to follow an entire string. In either case, Vizex will display a snapping cursor showing you the currently selected point. Exercise 4.3: Snap to features In this exercise, you’ll create a couple of new outlines and experiment with the various snapping and following functions. 1. Turn on the remaining Display objects by clicking their checkboxes. 2. Click on the Sectional geology interp object to select it. 3. Click the Graphic Editor toolbar button to turn on the Graphic Editor. 4. Click the New String toolbar button to create a new feature in the outline file. Vizex will change the cursor from the selection cursor to the filled crosshair, indicating that you’re now ready to digitise points. 5. Click the Snap button to activate snapping mode, ensuring snap to point is selected, and move the cursor around inside the Graphic Display. You’ll see the snapping cursor follow points in the current outline file. 6. Now select the Simple lithology trace display and Base of oxide display objects in turn and observe the behaviour of the snapping cursor. A dark green rock unit has been logged at the western side of the drilling, so let’s produce a simple interpretation of this unit. 1. Click on the Simple lithology trace display object to select it. 2. Move the mouse until the snapping cursor is at one of the dark green contacts and click. Vizex will add a point. 3. Repeat for the remaining five points that define the green unit – but don’t try extending the interpretation beyond the drillholes at this stage. 4. Once you’ve digitised the sixth point (without closing the shape), right-click and choose Close String from the pop-up menu. Alternately you can select the Close String button from the string editor toolbar. 5. Double click on a string segment in your newly created outline to set the Name (call it ANDS ) and set the Colour/Hatch as you see fit. Your display should resemble this diagram: Copyright © Micromine 2004 Page 59
- 151. MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) Notes: Now you’ll practice using follow mode by creating a hangingwall unit west of the HW1 outline. 1. Click the New String button to create a new feature. 2. Click the Sectional geology interp object to select it. 3. Position the mouse so that the upper, westernmost point in the MV1 unit is highlighted. 4. Drag the mouse down that western contact. As you proceed, you’ll see a faint dashed line appear along the line. When you’ve reached the bottom of HW1 , release the mouse. Vizex will immediately draw the shared contact. 5. Now click and drag along the lowest portion of the MW1 unit, so that your new hangingwall contact extends right to the bottom of the existing units. At this point your new feature should resemble the diagram on the following page. 6. Click the Snap button to turn off snapping mode and complete the remainder of the unit with an arbitrary shape. 7. Once you’re satisfied with your edits, click the sectional geology interp in the display window, and click the Graphic Editor button to turn off the Graphic Editor. You can save the edits if desired. 8. Select Edit | Remove All from the menu to clean up the display. Copyright © Micromine 2004 Page 60
- 152. MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) Notes: Follow mode Creating New Files Sometimes you might wish to create a brand new file within Vizex. For example, you might be starting a new sectional interpretation, or you might be doing air-photo interpretation or “heads-up” digitising. Creating new outline and string files is straightforward. First, double-click the desired Form Set Type (either Outline or String ) in the Form Sets pane to open the appropriate dialog. Then, when either the Outlines or Strings dialog appears, right-click the file name and choose New from the pop-up menu to create the new file. When you create a new outline file this way, Vizex simply creates the file and places the new filename into the Outlines dialog, ready for you to digitise. However, because a string file can have any structure you’ll have to define the structure before you can use the file. You might find it useful to keep a string file template handy to speed this step. We’ll create a new file when we do the Sectional Interpretation exercise a little later in the course. Copyright © Micromine 2004 Page 61
- 153. MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) A basic MICROMINE string file should consist of five fields, as listed here: Notes: EASTING, NORTHING, and RL fields, which should be given widths and precisions appropriate for your project. STRING field, which should be a character field with a width of between 5 and 20 characters. Use this as a label field to identify what a particular string represents (such as a road, fence, oxidation surface boundary, fault, etc.). JOIN field, which should be a numeric field with a width of about 8 characters and zero decimals. Vizex uses this to identify when one feature ends and another begins. Although Micromine recommends naming the fields as shown, you can use fields with any name as long as they suit the purpose. For example, it’s common to use a LABEL field as a string field. Your file can also contain as many additional fields as required. Working with Wireframes Creating DTM’s Vizex allows you to generate a wireframe directly from strings in the display, which is especially useful if you’ve just finished a pit design and want to produce a pit shell, or if you’ve edited some photogrammetric data and want to produce a DTM. To use this option, simply start the Graphic Editor, select the desired string file and then click the Create DTM button. You’ll be asked for a wireframe type and name, and then Vizex will produce the new wireframe. This function automatically uses the input strings as breaklines (great for contours, pit crests and toes) and if desired will automatically use a selected string as a constraint. Exercise 4.4: Create a topographic DTM First, let’s create the DTM: 1. Open the Saved Views node in the Form Sets pane and select the Lesson Four (b) form set. Contour lines will appear in the graphic display. 2. Click the Topographic con ours object in the Display pane to select it.t 3. Click the Graphic Editor button to activate it. 4. Ensure the Select tool is active. 5. Click the Create DTM toolbar button. 6. On the Build DTM dialog, double-click the Type response and choose DTM from the list. 7. Set the Name to TOPO and click OK . Vizex will build the wireframe. Copyright © Micromine 2004 Page 62

MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) Notes: Lesson 5 – Sectional Interpretation Duration: 30 minutes One of the primary reasons for displaying drillhole data is for interpretation. Normally, you’d display your drillholes, along with any ancillary data such as faults and oxidation surface boundaries, in a cross section or long section view, and do your interpretation right on the screen. After this lesson you’ll be able to: • Create new outline files for sectional interpretation; • Create and name outlines within those outline files; • Interpret features using both fact and interpretation. Prerequisites Before we start an interpretation exercise, let’s quickly summarise the prerequisites and conventions that you should use. The prerequisites involve simply validating and loading your data into the view. More formally, the prerequisites are: • You must have previously validated your drillhole data; • You’ve loaded the appropriate information into the display (assays, lithologies, any existing wireframe or outline interpretations, block models, or pit shells as required). You’ll use these objects as snapping targets while digitising; • The display is set to the correct orientation and clipping windows. You can set the display to any orientation, including 3D, for interpretation. Additionally, you can simultaneously edit in multiple windows, say in plan and crosssection. Naming Conventions MICROMINE has established a long-standing convention for naming outline files and the outlines within them. Although you’re not forced to use this convention in Vizex, your workflow will proceed more smoothly if you do. As you interpret each new cross section, you should do so in a new outline file, and you should name each new outline file using the prefix-number system: Copyright © Micromine 2004 Page 66
- 158. MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) • The Prefix is any 3 to 4 characters indicating what type of interpretation you’re doing – for example ORE for ore grade envelopes, GEOL for rock unit boundaries, and so on. Notes: • The Number is any ordinal number that indicates the progression of sections – you could just start at 1 and count upward, or you could number each file using the section’s northing or easting value. Within an outline file, you should name each outline according to the feature you’re digitising. If you’re digitising Number Four Lode, then give it a name like NO4. As you progress from one section (and therefore outline file) to the next, if it’s the same feature, keep giving it the same name. Where there’s more than one outline in an outline file, each outline must be uniquely named. So, if a particular feature bifurcates or splays, use a suffix (e.g. _H for hangingwall) to keep the names unique. Main_FMainMain Main ORE16000.OUT ORE15880.OUT ORE15760.OUT Exercise 5.1: Set up a new outline file Before we create the new file and begin our ore grade envelope interpretation, let’s prepare the display: 1. Open the Saved Views node in the Form Sets pane by clicking the small plus [+] icon next to it. 2. Double-click the Lesson Five object to load it. 3. Open the Drillhole Trace node in the Form Sets pane and double click your Simple assay display form set to load it. Copyright © Micromine 2004 Page 67
- 159. MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) 4. Open the Drillhole Value node and load your Statistical assay labels form set. Notes: Now we can create the new outline file and begin our interpretation: 1. Double-click the Outlines object in the Form Sets pane. 2. When the Outlines dialog appears, right-click the Outline file response and select New from the pop-up menu. 3. In the New Outline File dialog, type in the name ORE15900 and click OK . 4. Back on the Outlines dialog, set the Orientation field to Looking North, turn on the Name and Fill display options and click OK . Vizex will create the new file and place a new object into the Display pane. You’re now ready to start editing the new file and produce an interpretation. Interpretation Steps At this point it’s tempting to just launch in and start interpreting the ore grade envelopes, but as with most tasks a systematic approach will produce a better result. Generally, you should use a two-stage approach for your interpretation: • First, digitise the Fac s by snapping to all available information,t • Then, digitise the Interpretation by using the Insert Points tool, which you’ll most probably use with Snap turned off. Copyright © Micromine 2004 Page 68
- 160. MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) Notes: Why should you use this approach? Initially concentrating on the facts by snapping to existing points will provide Vizex with a full 3D coordinate framework for your new feature. By inserting the interpreted points into this framework, you allow Vizex to perform a true 3D coordinate interpolation, which produces the most accurate possible result. If instead you started freehand digitising, Vizex would be forced to put the new points exactly into the plane of the section, which might not correspond to the plane of the drillholes. Exercise 5.2: Digitise a new feature making use of all available data In this exercise, you’ll create a new ore grade envelope. The aim here is not to produce a geologically meaningful result, but to understand how to set up a new interpretation using the tools and techniques you’ve learnt so far. Therefore, don’t worry if your new feature looks a little creative. 1. Click the ORE15900 object in the Display pane to select it. 2. Click the Graphic Editor toolbar button to activate the Graphic Editor. 3. Click the Select toolbar button to activate the Graphic Editor Toolbar. 4. Click the New String toolbar button to start digitising a new outline. First, let’s digitise the Facts: 5. Click the Snap toolbar button to enable snapping, and then click the Simple assay display object in the Display tab to make it the current ‘snappable’ object. 6. Digitise an outline around some of the coloured assay intervals to produce a basic ore grade envelope. Don’t extend beyond the drillhole data at this point. 7. When you’re ready to close the outline, right-click and choose Close String from the pop-up menu. Copyright © Micromine 2004 Page 69
- 161. MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) Now we can focus on the Interpretation: Notes: 8. Click the Insert Points toolbar button to activate insert mode. 9. Click the Snap button to turn off snapping mode. 10. Insert points wherever you’d like by clicking on a string segment, then dragging the newly created point to its final location. At this point, you’ll note that this exercise feels very much like Exercise 2.3. We won’t repeat the same steps, so feel free to experiment with snapping to other objects in the display to build an interpretation to your own satisfaction. 11. Once you’ve finished your interpretation, click the Graphic Editor toolbar button to close the graphic editor. Answer Yes to save changes. 12. Select Edit | Remove All from the menu to clean up the display. Copyright © Micromine 2004 Page 70
- 162. MICROMINE Training v9.2Module 02 – Displaying and Manipulating Data (Rev 05) Notes: Lesson Five Summary In this lesson you learned about the sectional interpretation process. To name a new outline file using prefix-number : Prefix is 3-4 characters indicating the type of interpretation, and Number is any ordinal number. Remember: Each section goes into a separate file. To interpret a new feature: Digitise the Fac s using the Snap tool, and thent Digitise the Interpretation using the Insert Points tool To name a new outline in an outline file: Double-click it to open the Properties dialog. Name it according to the feature you’re digitising. If it’s the same feature from section to section, give it the same name. Use a suffix to name bifurcations and splays. To be automatically prompted to set the outline/string properties whenever you create a new feature: Select Options | Vizex from the menu, and Activate the String Editor tab, then Set the Prompt to edit properties on adding a new string? option. Good Practice You can break the entire sectional interpretation process down to a four-line summary; by remembering these four lines you’ll guarantee your sectional interpretation success! • One section, one file • Same feature, same name • Facts by snapping • Interpretation by inserting • Close Graphic Editor and Re-Open from one section to the next.

- 167. MICROMINE Training v9.2Module 03 – The 3D Viewer (Rev 03) Notes: Lesson 1 – The 3D Viewer Duration: 20 minutes Using the 3D Viewer you can load data sets and view them in 3D. In this lesson you’ll learn how to display drillholes and DTM’s in 3D. After this lesson you’ll be able to: • Use the 3D Viewer user interface; • Load data sets into the 3D Viewer; • Manipulate the 3D view; • Create a fly-through. Introducing the 3D Viewer The 3D Viewer enables you to validate, visualise and interpret large amounts of data quickly by studying it from different viewpoints. It’s also the primary environment for three-dimensional modelling of geological units, structures, and ore grade envelopes. You’ll learn to produce 3D models in the Advanced MICROMINE course. You can use any field to represent the Z-axis (usually height), and thus display 2D data in a 3D environment. For example, use assay values from sample data to represent as Z values, which can then be colour coded. Starting the 3D Viewer: There are Several methods to start the 3D Viewer; • Select 3D | Viewer from the main menu; • 3D toolbar button on the Main Toolbar • Open any form, or create a new form under the 3D section in the Form Sets Display; or • Load Any 3D object by selecting an object from the Display | 3D Menu. Exercise 1.1: Display geochemical sample locations Let’s load some simple 3D point data into the 3D Viewer so that we can familiarise ourselves with the environment: 1. Open up the Form Sets panel by moving the mouse over the tab. Copyright © Micromine 2003 Page 1
- 168. MICROMINE Training v9.2Module 03 – The 3D Viewer (Rev 03) 2. Under 3D viewer, double click on the Points icon. If there is nothing listed under 3D viewer in the Form Sets tab, click on the [+] sign next to the 3D Viewer Folder to expand the options. Notes: 3. On the Load Points dialog, double-click the File response and choose NVG_GCM from the file list. Leave the remaining responses set to their default values. 4. Click on the Forms button and save the form as Geochem Points. 5. Click OK to load the points. Note that opening an object in 3D Viewer does not close the Vizex window. If at any time you wish to return to your Vizex display, you can select the Vizex Window from the Window menu, or click on the Vizexdisplay on the Display Pane Now you’re ready to explore the 3D Viewer environment. Decoration The controls that appear around the lower edge and sides of the 3D Viewer are known as decoration . These controls provide a means of manipulating the contents of the view. Decoration is turned on by default when you enter 3D Viewer. The Default can be switched off by unticking Show Decoration on the 3D Environment Setup found under Options | 3D Environment. The decoration can also be turned off and on using View | 3D | Decoration. • The two thumbwheels at the bottom left corner of the window rotate the data about the X- and Y-axes of the screen . They work as if they were connected to an axle running through the centre of your screen. • The thumbwheel at the bottom right corner of the window moves your viewpoint in and out of the data. It’s called the Dolly wheel, which is a name inherited from the motion picture industry. Using this control is equivalent to walking toward or away from a scene whilst looking through your camera’s viewfinder. • The slider to the left of the Dolly wheel is the zoom control. This control is only enabled if the view is in perspective mode, and is equivalent to changing the zoom on your camera while looking through the viewfinder. The cluster of buttons at the right of the display contains the basic tools that you’ll use to manipulate the view and select data. The buttons are reproduced and explained below: Copyright © Micromine 2003 Page 2

- 170. MICROMINE Training v9.2Module 03 – The 3D Viewer (Rev 03) Notes: Menu Extra features become available on the MICROMINE Main Menu when 3D Viewer is opened. These menu options are summarised below; • The File menu contains options to manage your 3D files, print scenes and access file utilities. • Use the Display | 3D menu to load data as a 3D object. The different files you can load are listed as separate items on this menu. • The options on the Edit menu allow you to select loaded objects and display, remove them, or change their properties. You can also change the direction of the illumination and the background colour of the scene. • Use the View menu to select, save or restore a viewpoint. You can position the camera in plan view or according to a cardinal point, and then save this setting in a Form. You can also select (or clear) default viewing features, rotation axes, decoration, drawing style and mode. Options for changing the direction of the illumination, adding extra light sources and changing the background colour of the scene are also available under the View menu. • Use the Wireframe menu to view and select from the wireframe types in the current project, load wireframe sets and enter edit mode after loading a wireframe object. • Use the Plot menu to create a plot of your 3D data by selecting the 3D Plot function. • Use the Flight Path menu to generate, edit and save 3D fly-throughs of your data. The Form Sets Pane You use the Form Sets pane to select the form set objects you want to include in the 3D Display. Before you define a form set object as a 3D Object, you can modify the form set properties to control the way the data will appear in the 3D Display. To create a Form Set Object in 3D Viewer, select an option from the Display | 3D Menu, or alternatively, double-click an object type under the 3D Folder to create a new Form Set Object. If there are no objects displayed under the Vizex Folder in the Form Sets pane, simply click on the plus [+] icon to it’s left to expand the options. The Object Manager The Display Pane now replaces the Object manager in 3D Viewer in Previous Versions of MICROMINE. Objects displayed in a 3D Window are displayed under the 3D icon representing that 3D Window in the Display pane. Copyright © Micromine 2003 Page 4
- 171. MICROMINE Training v9.2Module 03 – The 3D Viewer (Rev 03) The Object Manager / Display pane provides your main means of manipulating objects in the 3D view. Notes: The Display pane allows you to select objects loaded in your 3D window, and modify the properties of any existing display object, hide objects within the display and delete objects. Loading Drillhole Data Drillhole Data can be displayed in two different ways within 3D Viewer. It can be displayed using Drillhole Databases like the VizEx Display uses, or ,use a uses a traditional drillhole setup. You’ll notice, however, that the two methods are substantially similar. There are only two significant differences between the two methods: • You must specify a fixed trace interval in the traditional method, instead of allowing MICROMINE to calculate it the way the Drillhole Database does; • If a traditional method is used, the 3D Viewer’s Colour Coding option can access any file in your project, rather than just the files associated with a particular drillhole database. Exercise 1.2: Load drillhole data Now, we can display the drillhole data: 1. Double click on the Drillholes icon under the 3D Folder on the Form Sets pane. 2. Select the Training Drillhole Database as shown below. 3. Select Colour code traces? and then click the Colour Coding… button. Make the following entries in the Colour Coding dialog box. Copyright © Micromine 2003 Page 5
- 172. MICROMINE Training v9.2Module 03 – The 3D Viewer (Rev 03) Prompt Setting Interval file: NVG_ASSY Colour field: AU1 Colour set: Drillhole Au1 (statistical) Notes: 4. Select Show Hole Names and Mark Collars. 5. Click on the Forms button, and save this form as Simple Assay Drillholes . 6. Click Close to return to the Load Drillholes dialog and then click OK to complete the process. The drillholes will be loaded into the display. Your display should look like this: Manipulating the View Exercise 1.3: Manipulate the 3D view Now that we’ve loaded some data, we can experiment with the various tools for manipulating the 3D view. 1. With the View/pan tool selected, drag the mouse within the view and observe how the view rotates in response to your mouse movements. 2. Now use the Rot X and Rot Y thumbwheels and observe how the view rotates around the screen X- and Y-Axes. These wheels are useful if you require more precise movement. Copyright © Micromine 2003 Page 6
- 173. MICROMINE Training v9.2Module 03 – The 3D Viewer (Rev 03) Notes:3. Use the Dolly wheel to move into the view. 4. Click the View All button and observe how the 3D Viewer dollys backward so that all of the data are visible. There are two very useful keyboard and mouse combinations that allow you to manipulate the view with greater freedom: 5. Hold the Ctrl key and drag the mouse. Doing this allows you to “pan” around the view. 6. Simultaneously hold the Ctrl+Shift keys and drag the mouse up and down the screen. This keyboard combination activates a dynamic zoom mode. Loading a DTM of the area around the drilling Digital Terrain Models (DTM’s) are mathematical models of a random set of data points that have X, Y and Z values. MICROMINE uses the Delaunay Triangulation algorithm to create DTM’s. By drawing lines between the data points, MICROMINE creates a mesh of triangles that become a DTM. DTM’s are most commonly associated with topographic data, with the Z-coordinate representing elevation. In this task you’ll load a DTM of the topography around the area where the drillholes are located. Exercise 1.4: Display a DTM Follow these steps: 1. Double click on the Wireframe icon under the 3D Folder in the Form Sets pane. 2. Double-click the Type response and select DTM from the list. 3. Double-click the Name response and select NVG_TOPO from the list. 4. Activate the Colour coding option and click More… 5. Select colour set 3 (titled NVG_TOPO DTM Colours ) and click Close. 6. Click OK to continue. The DTM of the topography will be displayed. Copyright © Micromine 2003 Page 7
- 174. MICROMINE Training v9.2Module 03 – The 3D Viewer (Rev 03) Notes:Exercise 1.5: Drape an image onto a DTM You can also “drape” an image over the DTM in the 3D Viewer. Typically you’d use this to display an aerial photo of the area. To drape an image: 1. Open the Display pane by clicking on the display pane icon if it is switched off, or moving your mouse over the display pane if it is minimised, or selecting the display tab. 2. Click on the DTM NVG_TOPO object to highlight it, right click, and select Properties. 3. Enable the Drape image? option and click More… 4. Click the browse […] button next to the Image file response and double- click the Import folder. Select the MMI_ MAGE.ECW file.I 5. Click Close to close the Image dialog. 6. Click on the Forms button and save the form as Topo with airphoto . 7. Click OK to close the Load Wireframe dialog. At this point the display should resemble the following illustration. You can control the transparency and degree of smoothing of the DTM by choosing the Change appearance option in the Load Wireframe dialog. Copyright © Micromine 2003 Page 8
- 175. MICROMINE Training v9.2Module 03 – The 3D Viewer (Rev 03) Creating a Fly‐through of the 3D Viewer Display Notes: A useful feature of the 3D Viewer is the ability to create, store and replay a fly- through of your data. The process involves repeatedly setting the view using the standard 3D Viewer controls and saving each view as a viewpoint in a fligh path file. Alternatively, you can create a flythrough from an existing string file. Once the flight path file has been created, it can be re-loaded and replayed using any data that exist within the same coordinate space as the original image. t When you’re editing or displaying a fly through, the 3D Viewer will display the flight path control panel underneath the existing toolbar. This control panel contains all of the tools that you need to record, modify, and play back a fly through. You use the control buttons at the left of the panel, shown below, to manipulate your fly through. P l a y S t o p F i r s t B a c k F o r w a r d L a s t I n s e r t A d d D e l e t e M o d i f y Exercise 1.6: Create a fly through by recording viewpoints To create a fly through: 1. Select Flight Path | New from the 3D Viewer menu. 2. Rotate and dolly or zoom the view to give a general overview of the data. 3. Click the Add control button. 4. Rotate the view about 45° and click Add a second time. 5. Tilt the view back so that you can see the drillholes underneath the surface and click Add. 6. Now dolly in slightly and click Add. 7. Repeat various combinations of these steps until you have displayed the data to your satisfaction. 8. Click the Play button to replay your fly through. 9. Notice that the number of markers on the slider bar (to the right of the control buttons) corresponds to the number of viewpoints that you added. If necessary, you can use this to advance to a particular viewpoint in the fly through. Copyright © Micromine 2003 Page 9
- 176. MICROMINE Training v9.2Module 03 – The 3D Viewer (Rev 03) 10. Select Flight Path | Close from the menu and answer No when prompted to save the file. You can re-load a previously saved fly through by selecting Fly Through | Open from the menu. Notes: Exercise 1.7: Create a fly through from a string You can also create a fly through using a string. If you create the string in VizEx and drape it onto a DTM, the fly trough will then follow the contours of the DTM. To make it realistic it’s a good idea to use the File Editor to increase the RL by a couple of metres, this then gives the illusion of moving at eye height. In the next exercise you’ll load a previously created string and initially watch how the camera follows the string. Later you’ll learn to control where the camera is looking. 1. Select Flight Path | Create from string from the 3D Viewer Menu. 2. Double Click the File response and open the NVG_Flythrough string file. 3. Right Click the File response and select the View menu item. Notice how the file contains a number of fields. Each point along the string represents a viewpoint. An RL must be specified at each point, and the Horizontal and Vertical angle of the camera can be set. Close the file editor. 4. File out the dialog box as shown bellow: Prompt Setting X field: EAST Y field: NORTH Z field: NEWRL String field: STRING Join field: JOIN Horizontal angle field: HORZ_ANGLE Default horizontal angle: 0 Vertical angle field: VERT_ANGLE Default vertical angle: 0 Flight Path File: NVG_Flight 5. When the flight path loads it will go to the first viewpoint. Make sure the Time response is set to at least 100 secs, then click the Play button. This tour will start with the camera following the string and then it will demonstrate different view angles. Sudden c hanges in direction will result in a ‘jerky’ flight path, so try to keep strings as smooth aspossible. Copyright © Micromine 2003 Page 10
- 177. MICROMINE Training v9.2Module 03 – The 3D Viewer (Rev 03) Notes:Lesson One Summary This lesson has covered the fundamentals of the 3D Viewer and has shown you how to work within the environment. Here’s what we’ve learnt so far: To manipulate a 3D View: Use the View tool and drag the mouse in the screen, or Use the Rot X , Rot Y , and Dolly wheels. To “pan” the display: Hold the Ctrl key and drag the mouse. To dynamically “zoom” the display: Hold the Ctrl+Shift keys and drag the mouse up or down the screen. To load an object: Choose Load | … from the menu. To change an object’s properties: Open the Object Manager, then Click the object in the Object list, and Click Properties. To create a fly-through: Select Flight Path | New from the menu, then Set each viewpoint and click the Add button. To create a fly-through from a string: Select Flight Path | Create from string from the menu, then Load the string file. Good Practice Use the 3D Viewer to confirm the spatial relationship between your 3D data sets. This is especially useful if you’ve completed a sectional interpretation and want to ensure that the interpretation matches the drilling.

- 178. MICROMINE Training v9.2Module 03 – The 3D Viewer (Rev 03) Notes: Lesson 2 – Creating Output Duration: 15 minutes In this lesson, you’ll learn to generate plot file, VRML, and JPEG output from the 3D Viewer for use in other applications. After this lesson you’ll be able to: • Save and recall a 3D view; • Create a MICROMINE plot from the 3D Viewer; • Create a JPEG image for display in a report; • Create a VRML file for display in a browser. Saving a 3D View for Later Re‐use Often, you’ll want to save a 3D View so that you can re-open it for later use. This is easy with the 3D Viewer: simply choose File | Save from the menu. It’s important that you set Save as type to Inventor Files if you want to re-open the view later. Exercise 2.1: Save the 3D View To save the view: 1. Select File | Save from the menu. Alternatively, click the Save toolbar button. 2. Type in a File name, and ensure that Save as type is set to Inventor Files . Click Save to save the file. Creating a Plot of the 3D Viewer Display There are two ways of creating hardcopy output from the 3D Viewer: • Create a plot file that can be plotted using the Plot Editor. However, this method doesn’t support advanced 3D view properties such as transparency and image draping, so the second method is usually preferred. • Create a JPEG of the display, which can be used in the Plot Editor in a picture frame or in any other application that can display JPEGS. Normally you’d save them as 150 DPI JPEGS for plotting. Higher resolutions are possible but may create very large files. Copyright © Micromine 2003 Page 12

Notes: Exercise 2.2: Create a 3D plot To create a 3D plot: 1. Select Plot | Generate from the 3D Viewer menu. Alternatively, you can click the Plot toolbar button. 2. Enter 3D_VIEW in the Plot file response. 3. Select Print as JPEG? 4. Double-click on Background colour and choose a light colour, such as white or pale cyan (sky blue). 5. Because we only require a low-resolution image for this lesson, set the resolution to 72 DPI . 6. Double-click the Paper size response (even though it appears to be disabled) and choose A4 . 7. Double-click the Layout response and choose No Title . Your dialog should look like this: 8. Click Run to make the plot. 9. The function will create two files, a PEL file and a JPG file. The PEL file is a standard MICROMINE plot file. It contains a link to the JPG file that contains the actual image created from the display. You can create a normal plot in the Plot Editor using the combination of the PEL and J PG file. Copyright © Micromine 2003 Page 13

MICROMINE Training v9.2Module 03 – The 3D Viewer (Rev 03) Notes: Saving a 3D View as a VRML File You can create VRML ( V irtual R eality Markup Language) files in the 3D Viewer and send them to colleagues that have an Internet browser (such as Internet Explorer™ or Netscape™) equipped with a VRML plug-in. Your colleagues can then display the 3D image in their browser in much the same way as you displayed it in the 3D Viewer. This technique is excellent for sharing 3D models with remote site offices or head offices where those people may not have access to a MICROMINE licence. Exercise 2.3: Create a VRML file To create a VRML file: 1. With the same 3D View displayed, select File | Save As… from the menu in the 3D Viewer. 2. Choose VRML Files from Save as type and enter NVG_VRML as the file name. Click Save to create the file, which will be given a WRL extension. 3. To view the file in Internet Explorer, select File | Explore Current Project and double click on the NVG_VRML.WRL The viewing software needs to be installed in order to work. MICROMINE recommends the Cortona VRML Client, which can be downloaded from the following website: http://www.parallelgraphics.com/products/cortona/ 4. The special VRML toolbars will load when the browser recognises the file type. Copyright © Micromine 2003 Page 14

MICROMINE Training v9.2Module 03 – The 3D Viewer (Rev 03) Notes: Lesson 3 – An Introduction to 3D Modelling Duration: 15 minutes Three-dimensional modelling is beyond the scope of this introductory training course. However, this lesson will provide a brief overview of some of the techniques that can be used when modelling solid polygonal features. After this lesson you’ll: • Have a basic understanding of the wireframing process. 3D Modelling You create 3D wireframes of solid polygonal features such as rock units, ore zones, and grade envelopes. It’s essentially a two-stage process. Firstly, you create a series of sectional interpretations through the desired object, and then secondly, you join those sectional interpretations to form a 3D wireframe. The following exercises will show you how to load outlines, which were created from a sectional interpretation, and begin constructing a wireframe from them. Exercise 3.1: Load outlines To load the outlines: 1. From the menu select Edit | Remove All to clean up the 3D view. 2. From the Form Se s pane, double click on the Outlines icon.t 3. Set the Orientation to PLAN . A common support request arises when C lients build wireframes from outlines loaded in the wrong orientation. It’s very important to load the outlines into the 3D Viewer in the same orientation that you created them, otherwise they’ll appearin the wrong place. 4. Double-click the Prefix response and select NV1N1 from the list. In this example, the prefix is NV1N and the first number is 1 . 5. Delete the 1 off the end of the file name so that the prefix response reads NV1N . 6. Set the Start number to 3 and the End number to 7 . By convention, MICROMINE outlines are named with a prefix and a number. This allows you to load multiple outlines by choosing the appropriate prefix and setting the start and end numbers. MICROMINE will load all outline files with numbers between those two values. Without this system, you’d be forced to manually load each individual outline file. Copyright © Micromine 2003 Page 16
- 183. MICROMINE Training v9.2Module 03 – The 3D Viewer (Rev 03) 7. Set (check) Use outline Z values? The dialog should now look like this: Notes: 8. Click OK to load the outlines into the 3D Viewer. These outlines represent an interpreted ore grade envelope from the NVG deposit. Each outline represents the interpretation of a single plan flitch; together they define the entire envelope at 5m intervals. Exercise 3.2: Start building a wireframe You can now start wireframing the outlines to produce a solid model: 1. Select Wireframe | New from the menu. This will put the 3D Viewer into wireframe editing mode and activate a series of new buttons on the toolbar. 2. Ensure that the Build Wireframe button is selected. 3. Use the thumbwheels at the bottom left of the screen to rotate the view so that you can see each outline as a separate object, with no overlap between them. 4. Click the Select Tool at the right of the screen or from the View Toolbar. You won’t be able to build the wireframe unless this tool is active. 5. Click on a line segment from the first outline at the single (i.e. non- bifurcated) end of the model. MICROMINE will highlight it in red. 6. Click a line segment from the adjacent outline. MICROMINE will move the highlight to this outline and construct a wireframe between them. The following diagram illustrates these two steps. 7. Repeat this process for the next few outlines. MICROMINE will progressively build the wireframe as you proceed. Copyright © Micromine 2003 Page 17
- 184. MICROMINE Training v9.2Module 03 – The 3D Viewer (Rev 03) You’ll probably notice that some of the wireframe segments have not been constructed correctly, and instead appear to be folded into themselves. You’ll learn how to correct or prevent this situation during the Advanced MICROMINE training course. The advanced training will also teach you how to validate wireframes, edit strings, create bifurcations, and more. Notes: First outline selected Second outline selected, MICROMINE builds wireframe 1. To save the wireframe object, select Wireframe | Save from the menu. 2. Double-click the ORE type. 3. On the Wireframe Properties dialog, set the Name to INTRO and set the colour to light red. 4. Click OK to save the wireframe, then select Wireframe | Exit Editor from the menu to return to the standard viewing mode. Notice how the wireframe colour changes to your selected colour. The khaki colour indicates that the wireframe is currently being edited; to avoid confusion you should avoid using this as the default colour. If you don’t have the wireframing module, you can still display representative solids of your outlines by selecting the Create solids? option in the Load Outlines dialog.

- 190. Lesson 1 –The Plot Editor Duration: 90 minutes In this module you’ll learn to create a hardcopy plot incorporating the plan and cross section plot files you created earlier. After this lesson you’ll be able to: • Load a plot file into the Plot Editor; • Make initial configuration settings; • Choose a layout template and configure paper size; • Enter plot titles; • Make advanced configuration settings. Introduction The Plot Editor allows you to create complex plots with multiple frames incorporating other plots, grids, legends, images and tables. It also gives you the ability to plot a section and plan in the same plot frame. The Plot Editor provides you with multiple output options. You can send the plot to a connected plotter or printer, or save it in PGL (HPGL), DXF, EMF or PRN formats. If you select a postscript printer driver and print to a PRN file, the output file will be in postscript format. Before sending the plot to an output device, you can create a title, include a legend, select a grid type and include text or a logo. You can also insert variables to make automatic substitutions with predefined or user- defined parameters. You can preview a plot on the screen before producing a hardcopy. Facilities are then available allowing you to zoom in on any part of the plot area or to apply a scaling factor to the complete plot or to labels and symbols. While in preview mode you can also dump the display to the Windows clipboard (for use in another application) or to a bitmap file. Loading a Plot File When you work with a plot file, you normally load it into the Plot Editor, configure it to suit your requirements, and then send it to an output device. The next few exercises will walk you through these steps.
- 191. Exercise 1.1: Loada plot file To create a plot: 1. Select Plot | Plot Editor from the main menu. Alternatively, you can click the Plotting toolbar button. 2. On the Plot Editor dialog, double-click the Plot file response and select NVGSEC_15760 from the file list. 3. When you select the file, Micromine will display this dialog: 4. Click Yes to import the parameters. At this point we’ve already given the Plot Editor enough information to run a preliminary plot, so let’s have a look at what we’ve produced so far. 5. Click OK on the toolbar to run the plot. It should resemble the following diagram. Observe how the plot appears distorted, and the drillholes are probably off-centre relative to the plot. 6. Once you’ve finished previewing the plot, close the graphic display window to re-display the Plot Editor dialog.
- 192. Import Parameters Whenever youload a plot into the Plot Editor, Micromine asks you to Import Parameters. Plot parameters define the content and appearance of the plot, and include things like: • X- and Y-scales; • Paper size; • Rotation; • Grid line spacing. When you select Yes, the parameters associated with the plot file are used. If you’re loading the plot for the first time, you’ll get that plot’s default parameters, but if you’ve already loaded and configured the plot, Micromine will use the latest parameters. When you select No, the parameters currently shown in the Plot Editor are used. This is useful for those times when you want to make several plots, all having the same appearance – just set up the first plot, and then load the remaining plots, answering No in each case. Output The Plot Editor has numerous Output modes. You’ll most often use PREVIEW mode, since this mode shows the page layout as it will appear on the printed page. While you’re previewing a plot, you can move, add, and delete labels, as well as add other information (such as other plots, logos, tables, etc.) to the plot. HARDCOPY mode simply sends the plot to the desired printer or plotter. Using FILE mode, you can output the plot in a variety of different file formats. Output File Formats Each output file format is suited to a particular task. The most common ones are summarised here: • PGL: An old pen plotter language, rarely used nowadays; • DXF: Use this to share plots with drawing and GIS programs. You can output plots in real- world coordinates, allowing them to be directly overlain with other GIS data; • EMF: Use this to share plots with other Windows™ programs such as PowerPoint™; • PRN: Produces a binary file in the chosen plotter’s native language. If you choose a PostScript plotter driver, the output file will be a PostScript file. Style The Plot Editor supports three different plot Styles. You’ll make most of your plots using the SCALED style, which literally allows you to plot to scale. The STATISTICAL style is useful for plotting graphs or histograms, where the actual scale of the plot is irrelevant. SECTION+PLAN allows you to plot cross-sections with a plan window. The plan window is smart and automatically tracks the section settings. To make use of this option, create a plan plot that encompasses the entire project, and allow Micromine to vary the plan plot’s parameters to suit the currently chosen section.
- 193. Configuring a Plot ThePlot Editor dialog, below, allows you to configure a plot to your satisfaction. Settings can be as simple as choosing a paper size, or as complex as creating a plot from multiple plot frames. Paper Size The Plot Editor supports numerous paper sizes. However, because paper sizes are stored as form sets, you can easily define your own custom sizes in addition to the standard ones provided. To choose a paper size, simply double-click the Paper size response (even though it’s greyed out – this only means you can’t directly type into it) and choose from the list. Plot Layout Layouts are templates that define which frames will appear on a plot, their positions and their characteristics. The Plot Editor provides numerous predefined layouts, but as with paper sizes it’s also easy to create your own and save them as form sets. The predefined layouts define where the title frame will be positioned on the sheet of paper. To select a layout, double click the Layout response on the main Plot Editor dialog. We’ll be using the BOTTOM Plot Layout for this lesson, which appears as shown here:
- 194. You can seethat the Mas er Plot Frame , which contains the actual plot data, occupies the bulk of the plot area. Beneath that is a title area consisting of six small frames. We’ll look at placing data into some of these frames (specifically NOTES , TITLE , and CLIENT ) in later exercises. t Plot Definition You use the Plot Definition group to finely control parameters such as the Plot Area, X - and Y -Scale, and the real-world plot extents. These parameters all work together, and it’s important to realise that whenever you change one, the others will automatically update in response. The parameters that you’ll change most often here are the two Scales, and the Centre coordinates. By modifying these (and the Paper size), you can re-size and re-centre the plot data on the plot area. All of the remaining parameters are dependent on these settings. Until you are experienced with using the Plot Editor, there are some parameters that you should try to avoid changing, because you might produce a situation where Micromine expects an impossible paper size. They are Changed by scale, which should remain set to M I N / M A X , the Plot Area, which is dependent on (and set by) the Paper size, and the Minimum/Maximum values, which are affected by nearlyevery other parameter.
- 195. Exercise 1.2: Setthe plot definition parameters As you can see in the Plot Definition group, the X- and Y-scales of our plot are different (and arbitrary), plus the preview revealed that the plot contents are off-centre. 1. Set the Paper size to A4 . 2. To accommodate this new paper size you’ll now have to adjust the plot scale in the Plot Definition group. 3. Click the Auto Scale button (the left hand one, as shown below) to have Micromine pick a best-fit scale for the current plot area and paper size. 4. Click OK to run the plot and check the fit. If the fit is poor, close the graphic display window and enter different X - and Y -Scales, then click OK to redisplay the plot. 5. Move the mouse cursor around on the graphic display window and observe the coordinate display at the lower right of the screen. Position the mouse at what you perceive to be the centre of the data (not the centre of the window!) and note down the coordinates. 6. Close the graphic display window and enter those coordinates into the X - and Y -Centre responses in the Plot Definition. (The X-Centre should be about 25025 , and the Y-Centre about 1510 .) As you edit each value, observe how the Minimum and Maximum values automatically update. 7. Click OK to run the Plot Editor again. The section now appears about right. 8. Close the graphic display and return to the main Plot Editor dialog when you’re done.
- 196. Coordinate Grid Depending onthe parameters you chose when you initially created the cross section, your plot might not have a coordinate grid displayed. However, it’s easy to set up a coordinate grid display using the Plot Editor’s Grid option. Exercise 1.3: Set up a coordinate grid display The Grid dialog has numerous settings on it, but for now we’re only interested in setting up a basic coordinate display. 1. On the Plot Editor dialog, set the Grid? option and click More… 2. Fill out the lower part of the Grid dialog as shown here: 3. Click the More… button at the top centre of the Grid dialog, and when the Grid Parameters dialog appears, set the Font to Tahoma . 4. Close the dialogs and click OK on the Plot Editor toolbar to re-run the plot. A 100m coordinate grid now appears on the plot. 5. Close the graphic display window once you’re done viewing the plot. Title Frames The Plot Editor uses a powerful method of managing plot titles: Each title is saved as an entry into a text file. When a particular title is required for a plot, it’s simply chosen from a list. This technique offers significant advantages over typing the title text directly onto the plot or into a dialog, because it allows you to create a library of titles. To access a title, you need to specify the name of the text file containing that title, and the Data Set that defines the title itself. The following exercise explains how to use this technique. Exercise 1.4: Set up title frames To set up the TITLE frame: 1. Click the Title Frames… button on the Plot Editor dialog. 2. If you inspect the Text Edit (Title Frames) dialog, you’ll notice that it contains form sets called NOTES A , NOTES B , TITLE , and CLIENT . Because the Layout is set to BOTTOM , these are the available frames; different layouts may contain different frames.
- 197. 3. Double-click TextFile column in the TITLE row and choose TITLE from the file list. 4. Right-click to open the file. 5. Edit the values in the first two rows (TITLE-0 ). Make the entries Introduction to Micromine , and Training Plot . 6. Close the File Editor and answer Yes to save the file. 7. Back in the Text Edit dialog, double-click in the Data Set column of the TITLE row and select the data set you edited - TITLE-0 in this case. Choosing a Data Set worksa bit like a filter, instructing the Plot Editor to “select only those lines whose DATA_SETcolumn containsthe text TITLE-0”. 8. Close the Title dialog and return to the Plot Editor. 9. Run the Plot Editor again (click OK ) to check the results. You can create any number of Data Sets in the TITLE PED file, which can contain different title information (say, for different projects). Simply select the appropriate Data Set when you’re setting up your plot. . Advanced Configuration So far we’ve set up a basic but functional plot. Now let’s look at ways to improve the plot’s functionality. Plots are generally made up of a series of components such as legends, other plots, tables, images and so on. Each component of a plot is contained in a separate frame. To add frames to a plot you must define its characteristics in the Layout Definition. Layout Definition The Layout Definition dialog allows you to set advanced plot properties. Perhaps the most common task you’ll complete using this dialog is to add more frames to the plot. The lower portion of this dialog is dedicated to this task, whereas the upper portion describes the main plot area.
- 198. Frames are usuallypositioned in this dialog using the USER Coordinate system. With this system, the lower left hand corner of the plot area is always (0,0), and the upper right hand corner is always (1000,1000), regardless of the chosen paper size. Even if you change the paper size while you’re setting up the plot, the coordinate system remains the same. The following diagram shows how the USER coordinate system applies to the BOTTOM layout. New frames are always positioned with a top right coordinate of 1000, 1000. You should resize your new frames before moving them to their new location, since this makes the coordinates easier to work with. Adding a Legend Most geological plots contain a legend, which summarises the various patterns and colours for assay grades, rock units, and so on. The next exercise will show you how to set up a legend as a frame on a plot.
- 199. Exercise 1.5: Adda legend To add a legend frame: 1. Click the Layout Definition… button on the Plot Editor dialog. The dialog shown previously will appear. 2. The information in the upper portion of this dialog describes the main area of the plot. You define additional frames in the lower portion of the dialog. 3. To add the legend, pull down the first Frame Type list in the lower part of the dialog and choose LEGEND from the list. 4. Position the cursor in the Form Set column and enter MMI_Lithology as the name of the legend form set. 5. Right-click the Form Set. You’ll be told that the Set does not exist, and will be prompted to create it. Click Yes. The Legend Frame Layout dialog will appear. 6. Click the Load button at the right of the dialog. 7. Choose TEXT COLOUR SET from the Type list and then double-click in the Set number response. A list of all the text colour sets in the project will be displayed. 8. Select the Lithology colour set you created in Module 2. 9. Click Load on the Legend Load dialog. The colour set will be loaded into the Legend Frame Layout dialog. 10. Close the Legend Load dialog. Your Legend Frame Layout dialog should now look like this: 11. Click OK to return to the Layout Definition dialog. 12. Enter the following to define the size of the legend frame. Prompt Setting BLx (Bottom Left): 900 Bly: 771 TRx (Top Right): 1000 TRy: 1000
- 200. Coords: USER These entrieswill position the legend in the top-right hand corner of the main plot frame. 13. Leave the other prompts in their default state and click Close to return the Plot Editor dialog. 14. Run the Plot Editor again to observe the changes you have made. It should look something like the following diagram. 15. Close the graphic display to return to the main Plot Editor dialog once you’re done. Modifying the Plot Date There are many other advanced settings that you can make. A common setting is to configure the Plot Editor so that either the creation or plot date of a particular plot is automatically displayed in the SCALE frame. These settings are stored in a text file that configures much of the Plot Editor. The next exercise will explain how to make this setting. Exercise 1.6: Configuring the plot date To configure the plot date: 1. Click the Layout Definition button to display the Layout Definition dialog. 2. The SCALE frame is part of the MM BOTTOM title area, so we need to edit this form set. 3. Right-click the MM BOTTOM form set, situated near the top of the dialog.
- 201. 4. The TitleFrame Layout dialog lists all of the frames that make up the MM BOTTOM form set. You can see that the COMPLEX frame contains a Form Set called SCALE , so right click that form set to edit it. The Complex Frame Layout dialog contains many settings, but we need only use this dialog as a means of accessing the underlying Data Set, which is also called SCALE . 5. The SCALE data set should be highlighted by default, so just right-click to edit it. 6. The file COMPLEX.PED will open into the File Editor. Scan through the SCALE Data Set entries until you find a line containing the text @plotdate . (This text appears on lines 54 and 90; you must perform the following steps in both places.) 7. If you’d like to automatically print the creation date of the plot, substitute @plotdate with @cddmmyy . 8. If, on the other hand, you’d like to print the plot date of the plot, substitute @plotdate with @ddmmyy . 9. Close the File Editor, answering Yes to save changes. 10. Click OK or Close on all of the dialogs to return to the Plot Editor. 11. Click OK to run the Plot Editor, and zoom in on the SCALE frame. Whereas the date was previously set to an arbitrary date, you’ll see that it now displays today’s date. @plotdate, @cddmmyy, and @ddmmyy are Plot Editor sub stitutio ns , which are covered in more detail in the Advanced Micromine course.
- 202. Lesson Summary This lessonhas introduced you to the Plot Editor and the process of creating a plot. Here’s what we’ve learnt: To choose a Paper size or Layout: Double-click the Paper size or Layout response. To set the plot scale: Click the Auto scale button, or Type in the X- and Y- Scale. To reposition the plot data in the plot: Hover the mouse over the centre of the data, and Note the coordinates, then Type the coordinates into the Centre responses.

You can use macros to automate a variety of MICROMINE tasks, including the Plot Editor. After this lesson you’ll be able to: • Define replaceable parameters on dialogs; • Save dialogs as form sets in preparation for macro execution; • Write a macro file; • Run a macro file. Introducing Macros Macros are an important part of MICROMINE, since they allow you to automate MICROMINE processes. A macro is simply a file containing a list of instructions that allow MICROMINE to perform a sequence of commands without further input. Once a macro is set up, you can run it repeatedly without intervention. You can include any function that appears on the MICROMINE menu as a macro instruction. Why Write Macros? There are numerous reasons for writing macros, but they usually belong to one of two primary tasks: • Repetition. Macros allow you to perform the same operation many times without having to sit at your computer. A classic geological example involves plotting many cross sections at the conclusion of a drilling programme. In this case the macro would repeat the same drillhole function as many times as there were cross sections. • Perform Complex Tasks. It’s possible to perform a complex task with a macro by stringing together a chain of simple commands. For example, you might regularly extract assay files from a database, perform a significant intersections grade calculation, and report the results. These three simple tasks could be combined into a single macro that would automate this repetitive task. You can combine both primary tasks using advanced macro writing techniques. You can also increase the flexibility of your macro by prompting the user for values during execution. You’ll learn to write these advanced macros in the Macros 2 module, which is part of the Advanced MICROMINE course. Copyright © Micromine 2003 Page 1
- 208. MICROMINE Training v9.2Module 05– Macros 1 (Rev 02) Creating a Macro Notes: Writing and using macros is a three step process: 1. Create, test, and save all form sets that will be accessed by the macro; 2. Write the macro file, referencing the previously saved form sets; 3. Run the macro and check the result. The following topics describe these steps in detail. Creating Form Sets The easiest way to create form sets for a macro is to use MICROMINE in the normal way. In other words, you simply choose a menu option, fill out the dialog, and if possible run the function with some trial data. You should continue to test the dialog until you’re satisfied with the result. Once you’ve prepared the dialog, consider which responses on that dialog will change each time it’s run from a macro. For example, if you were plotting cross sections, the Section number would probably change each time that function was run. After you’ve identified the responses whose values will change, substitute the trial data values with Replaceable Parameters . These parameters are identified by a % (percent) symbol followed by a number, for example %3 , and will be replaced with actual values when the dialog is run from the macro. You can define replaceable parameters %1 through %15 . Copyright © Micromine 2003 Page 2

To create a new macro file, you either choose File | New oose Tools | Macros | New. The macro ere’s no need to use a template in either case. ly Notes: 4. Select Edit | Remove All from the main menu to clear the Vizex Screen. Editing a Macro File O the macr and set the Type to MACRO , or ch structure is well defined, so th Macro files are ordinary MICROMINE files, so you can use all of the standard data entry shortcuts like Ctrl+A (add) or Ctrl+R (replicate). Additionally, the Process and Form fields in the macro file have permanently attached lookup tables to simplify the macro writing procedure. The Process lookup table simp reproduces the main MICROMINE menu, and the Form lookup table lists the saved form sets corresponding to the chosen process. When you’re writing a macro, each line represents a single step or “process”, which usually requires you to specify three pieces of information: . The Process, which corresponds to the menu item you’d have chosen if1 you were performing the same task manually; 2. The Form, which allows you to choose the appropriate form set; Copyright © Micromine 2003 Page 5

These represent the values you’d have typed into the dialog if you were performing the task manually. Notes: During Normal (non-macro) use, when you type a value directly into a dialog, Micromine just uses that value. During a Macro, Micromine searches the dialog for replacable parameters. Values for these are extracted from the matching %-fields in the macro file. Most Process settings correspond to main menu options, but there are a few special commands that apply only to macros, the most common of which are: • ABORT: Type YES into the Form field to make the macro terminate if an error occurs; • COMMENT: Forces the macro to ignore all subsequent text on that line. You can use this to label the fields in your macro file. In addition, some functions, such as File | Modify, can’t be saved as form sets in the normal way. However, you can still use these in macros by selecting them from the Tools | Macro Functions menu. Finally, if you’re writing a macro that involves creating plot files, you must type the name of the output plot file into the Plot File field. The Plot File field serves only one purpose: to reproduce the Generate Plot File dialog that pops up whenever you manually create a plot file from a graphic display. Copyright © Micromine 2003 Page 6
- 213. MICROMINE Training v9.2Module 05– Macros 1 (Rev 02) Notes: Exercise 1.2: Write a macro file Now it’s time to write the macro itself: 1. Select Tools | Macros | New from the main menu. 2. When the New Macro File dialog appears, type in the Name DH_SECTION and click OK . You’ll see a blank macro file appear in the File Editor. Observe how the Process and Form fields have lookup table buttons. 3. Click the Process lookup table button and note how the popup menu reproduces the main MICROMINE menu. Select Display | Vizex | Saved View from this menu. 4. Click the Form lookup table button and select your saved form set from the list. Once it’s chosen, you can edit the form set by right clicking in the Form field. You can also create form sets for simple dialogs (for example, File | New) without leaving the File Editor. Simply choose the required Pro c e ss and right click the Fo rm field to display the appropriate dialog. 5. Press Enter to select the second line in the macro. 6. Click the Process lookup table button, and select Display | Vizex | Display Limits from this menu. 7. Click the Form lookup table button and select your saved display limits form set from the list. If you remember the Display Limits dialog from the previous exercise, Section corresponded to %1, Window towards was %2 and Window away was %3. Knowing this, we’re now ready to place actual data values into the matching fields of the macro. 8. Type the value 6945200 into the %1 field, and 50 into both %2 and %3. 9. Finally, type the name 6945200mN into the Plot File field. At this point it’s worth exploring the similarities between this macro and performing the same task manually.

- 214. MICROMINE Training v9.2Module 05– Macros 1 (Rev 02) • You select The Saved view from your Form Sets Tab in Vizex to load your required data. Notes: • You select the Display Limits process from the toolbar This is exactly like making the same selection from the main menu. In other words, choosing a process within a macro is the same as making a menu selection during a manual run. • You chose a saved form set. This is just like choosing Forms and then clicking Open after you’ve opened the desired dialog or selecting a from from the Form Sets Tab. • You typed values into the %-fields. This is equivalent to typing those values directly into the dialog. In comparison, when you run the macro, MICROMINE sees the %-values in the dialog and searches the matching %-fields in the macro for actual data values. • Finally, you typed a Plot File name. This corresponds to the name you’d type into the Generate Plot File dialog after clicking the Plot toolbar button. Let’s finish the macro: 1. Select Records | Increment from the File Editor menu and type a value of 100 into the Increment Value dialog. 2. Highlight the 15760 value in the %1 field and press Ctrl+A five(5) times. There should now be nine lines in the macro and the last %1 value should read 16000 . 3. Highlight the 6945700mN value in the Plot File field and press Shift+Ctrl+A. Click OK on the Increment Many dialog to update the values. 4. For each of the fields Process, Form, %2, and %3, highlight the first value and press Ctrl+Shift+R . Your macro file should now look like this: 5. Save the macro and close the editor. You’ve now written a macro that will automatically make nine plot files. In reality, your Window towards (%2) and Window away (%3) values would probably vary slightly from section to section. For this lesson we’ve saved time by assuming they’re allthe same value.

- 215. MICROMINE Training v9.2Module 05– Macros 1 (Rev 02) Running Macros Notes: Running a macro means executing the commands stored in the macro file. You don’t run the macro file itself, but call the file from the Run Macro dialog. You can include up to 42 macro files in the one run. This allows you to create smaller files, which are easier to test, and then combine them to create complex operations. To run a macro, select Tools | Macros | Run from the menu. You can enter the names of all the macro files you want to execute into the Run Macro dialog. They’ll be processed in the order you enter them. If you’d like to start with an intermediate macro, simply select the Start At button next to the file where you’d like to begin. The files before it will be ignored. You must also enter a compulsory report file name. It’s essential that you check this file after the macro has run, since any popup messages that would have been displayed during a manual run will be written to this file. At the very least you should scan the report for errors, which will always be highlighted with blocks of hash ‘#’ symbols, like this: Time: 08:48:48 #### ERROR IN COPY STRUCTURE #### ---------------------------- Exercise 1.3: Run a macro Now you can check the result of your efforts: 1. Select Tools | Macros | Run from the menu. 2. On the Run Macro dialog, double-click the Macro Name at row number 1 and choose DH_SECTION from the list. 3. Type the name DH_SECTION into the Report File response. If you give the report file the same name as the macro, you’ll be able to track which reportscorrespond to which macros. 4. Click the Run button and observe the result. 5. If you watch carefully, you’ll be able to see %1 being replaced with actual values on the Normal Sections dialog. You’ll also be able to see the sections changing in the graphic display. 6. Once the macro is finished, right-click the report file name and view the contents. Any error messages will be reproduced here. Close the report file once you’re satisfied. 7. Finally, close the Run Macro dialog. Copyright © Micromine 2003 Page 9

It is essentially a group of Macros available to use with your own data. The MICROMINE Toolbox provides a way to run processes that are not available as a single function. The Toolbox project contains a set of macros that can be used to manipulate data in any of your working projects. You invoke a Toolbox process by opening the Toolbox project and then running the appropriate macro. Copyright © Micromine 2003 Page 10
- 217. MICROMINE Training v9.2Module 05– Macros 1 (Rev 02) Notes: Lesson Summary This lesson has introduced the concepts of macro writing. The topics that we’ve covered so far are: Writing a macro involves three steps: Create the form sets, with replaceable parameters; Write the file; Run it! To set up a form set: Use MICROMINE as normal, then Define the replaceable parameters, and Save the form set. For each process in a macro file, you must generally provide three items of information: The Process (i.e. what menu you’d have manually chosen); The Form (i.e. which form you’d have manually loaded); The replaceable parameter values (i.e. what you’d have manually typed into the dialog). Good Practice Keep your macros short and restrict them to achieving a single outcome whenever possible. Short macros are much easier to maintain. If required, you can string together simple macros in the Run Macro dialog to perform a more complex task. Always view the report file after running a macro. Giving report files the same names as the macros will allow you to track the relationship between them. MICROMINE Toolbox is a project attached with installation. This project allows you to carry out processes not available within MICROMINE Help Topics For information on: See: Macros Macros: Overview (or, choose from many topics) Toolbox Toolbox Help Copyright © Micromine 2003 Page 11
