The document summarizes exploration work done on the Major Hart property, which contains a pluton that shows highly anomalous stream sediment geochemistry indicative of a rare-element granite. Several key points are made:
1) Stream samples from the property contain anomalies of rare earth elements, tin, tantalum, and tungsten that are amongst the highest levels in BC.
2) The pluton shares similar geochemistry with deposits elsewhere that contain rare earth element pegmatites and tin mines.
3) Distal dykes from the pluton are associated with high-grade gold veins, and the property has potential for contact-related gold and emerald deposits.
4) The property
I spent 7 weeks individually mapping an area of 14Km2. Strath lies on the eastern periphery of the Cuillin centre, and contains exposure of formations from Pre-Cambrian Torridonian sediments, to Palaeogene Igneous complexes.
I carried out geological field mapping, whilst conducting research to study the composition and origin of the formations. This poster was submitted with a separate report.
The project has stimulated my curiosity in structural geology, particularly faulting and folding. I observed a fascinating uncomfortable relationship between tertiary igneous intrusions and Ordovician carbonates.
Towards the coast are Jurassic Shales that allowed me to explore subsurface fluid flow and observe well preserved marine fossils.
I achieved a first-class grade for my dissertation.
Petroleum exploration project on the Halfway Formation in the Dimsdale Oil Field, working alongside another student geologist by analyzing the depositional environments, hydrocarbon trapping methods, oil-water contact, well interpretation, basin model building, and volumetric measurements on hydrocarbons.
TURBIDITES: MODE OF FORMATION OF TURBIDITES AND ITS ECONOMIC IMPORTANCEJames Opemipo OLOMO
Turbidites are deposits resulting from turbidity currents. They are gravity driven sediments derived mostly from the continents and are deposited on the ocean floor when the transporting medium loses its energy. These turbidite deposits are sealed most times by shales to form a stratigraphic trap. If the factors required for hydrocarbon accumulation in a petroleum play system are prevalent, then the turbidite will most likely serve as a good reservoir to house hydrocarbon. Our modern day economy requires enormous amount of energy to meet the energy demand and hydrocarbon unarguably is a non-renewable resource. Perhaps its worth mentioning that the decrease in reserves. And it has been established that turbiditic deposits help to host important economic resources such as hydrocarbon, when the right conditions are emplaced. Hence, the need to understand their formation for exploration success.

Uranium Deposits
Uranium is a very dense metal which can be used as an abundant source of concentrated energy. It occurs in most rocks in concentrations of 2 to 4 parts per million and is as common in the earth's crust as tin, tungsten and molybdenum.
.
There are three main types of uranium deposits including 1. unconformity-type deposits, 2. paleoplacer deposits and 3. sandstone-type (roll front) deposits (Figure 1). Sandstone-type deposits are abundant in sedimentary rocks of the Colorado Plateau and found on the Navajo Nation. This type of uranium deposit is easier and cheaper to mine than the other types because the uranium is found near the surface of the Earth. These deposits formed when oxidized groundwater that had leached uranium from surface rocks flowed down into aquifers, where it was reduced to precipitate uraninite, the primary ore mineral of uranium. In some deposits, like those found on the Navajo Nation, reduction took place along curved zones know as roll-fronts, which represent the transition from oxidized to reduced conditions in the aquifer.

GeoCongress 2023 - Classifcation of Rooikoppie Gravels: Wouterspan Case StudyRichard Graeme Horn
T
he Wouterspan project property is located along the north bank of the
Middle Orange River, between Douglas and Prieska in the Northern Cape
Province of South Africa (figure 1), which area has been the site of intense
alluvial diamond activity since the 19 th century. The bedrock of the Orange
River valley between the confluence of the Vaal and Orange Rivers at
Douglas and Prieska is dominated by flat lying Dwyka tillite and siltstone of
the Karoo Supergroup. Underlying the Dwyka are lavas of the Ventersdorp
Supergroup, which are overlain (in places) by sediments of the Griqualand
West Supergroup, comprising shales, quartzites and dolomites. The
bedrock is cut by faults and dolerite dykes, which are rarely exposed.
The Wouterspan deposit comprises an extensive flat lying alluvial sequence,
on which a number of terraces have been identified (figure 2). The majority
of the alluvial diamonds found in gravel deposits along all of the middle
Orange River terraces are, typically, found in two distinct gravel horizons.
These comprise an upper, deflation deposit (locally known as Rooikoppie
gravels) overlying fluvial alluvial units, often known as Primary Alluvial
Gravels. Both deposit types have been seen to be developed extensively
on Wouterspan.
W
hile being ubiquitously worked along the both the Vaal and Orange
Rivers for over one hundred years (Marshall et al ., 2009; 2017), the
Rooikoppie Deflation Gravels have received significantly less scientific and
economic investigation than the kimberlites and diamondiferous alluvial
gravels located within the same environs.
A classification tool was created and applied to surface mapping and
exploration pitting on the Wouterspan Diamond Project . The aims of the
classification were to:
1.
Develop an effective tool that can describe and
categorise different types
of deflation gravel based on clast size
2.
Compare and then determine if there is a relationship between the
deflation gravel and the underlying geology
With the geological relationship established, the classification tool, when
used in conjunction with associated geological and geomorphic studies will
provide a better understanding of post depositional events while being
able to be generate targets for bulk sampling.
O
n Wouterspan, both colluvial and eluvial Rooikoppie gravels (figure 3)
were identified. The colluvial variety is a fine gravel lying directly on top of
calcreted tillite. The implication of this is that the gravels have been derived
from terraces higher up the slope. As a result, this Rooikoppie gravel unit
might be expected to have inherited more than one diamond population.
The
top few metres of each of the older channel have been variably
calcretised and are, in turn, covered by thin Rooikoppie gravels. Surface
mapping and pitting indicate that:
•
A coarse (Cobble dominant) Rooikoppie (figure 5) generally overlies the
older channels.
•
Finer (Pebble dominant) Rooikoppie is found to occur over the
younger channel, as

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Major Hart Project Salient Points
1. Major Hart Project Salient Point Summary
No detailed exploration has been done on property. BCGS RGS stream sampling and
GSC regional mapping at 1:50,000 scale are the only previously recorded work.
The Major Hart Pluton had an extremely evolved, fractionated source melt demonstrated
by rubidium and fluorine anomalies, and “alaskite” composition. Abundant fluorite was
noted at the contact with the ultramafics, readily visible from horseback (H. Gabrielse,
personal communication 2010). The rubidium RGS stream results are some of the highest
in the province of B.C., and constitute the most localized single cluster of significant size.
The stream geochemistry is indicative of a specialty, or “tin-type” granite. It should be
noted the Tanco Mine, Manitoba was found while investigating the area for tin potential.
Tantalum stream sample results are 5 times stronger than surrounding the Fir-Verity area.
Of the 7 samples comprising the Major Hart anomaly cluster, 7 are >99th percentile for
Bismuth, Lutetium, Rubidium, Tantalum & Tungsten; 6 are >99th percentile for Fluorine in
water; 5 are >99th percentile for Ytterbium, and 4 are >99th percentile for Cesium & Hafnium
in comparison to the B.C. provincial RSG stream sample database. The partial rare earth
element results to date indicate a propensity towards the more valuable heavy rare earths.
The pluton has similar stream sediment geochemistry to the Surprise Lake Batholith
(Ruby Creek mine, 115 Minfile showings), Glunderberry Batholith (Swan), Ash
Mountain, and Storie Moly areas. A linear trend is evident through these areas, ending at
the Major Hart Pluton.
The closest match to the tenor of the anomalous stream samples in the Canadian
Cordillera is the O’Grady Batholith, NWT, which contains a 10 km long elbaite-type,
rare-element pegmatite, up to 1 km wide, at the head of the anomalous drainages. It is
located 100 km NW of Tungsten, NWT. The pegmatite was discovered while researching
anomalous stream samples with potential pegmatite indicator elements. The stream
samples at the O’Grady area contain lower level anomalies than the Major Hart area.
The stream sample anomaly cluster is very well constrained. The northern contact of the
Major Hart Pluton with the enclosing rocks is at the head of all of the anomalous source
drainages, although the rest of the pluton’s drainages are still elevated in the elements
associated with fractionated granites.
The Major Hart Pluton is situated at the crossroads of Slide Mountain Terrane, Ancestral
North America, and Dorsey Assemblage. The regional structure present is sufficient to
have allowed the pluton to tap a considerable volume of melt, possibly including a mantle
component. Since the pluton is the only Eocene intrusion within 120 km, the volatile
phase of the melt may have had a considerable volume of rock/melt from which to
concentrate the incompatible elements.
The anomalous stream drainage trend, and coincident pluton-host contact zone is
over 10 km long.
2. Distal dykes and probable outliers of the Major Hart pluton have a strong association
with gold at Nizi and Yursi vein showings, and probably underlie Beale Lake system, 15
to 20 km from exposed pluton. Gold is associated with bismuth-tungsten anomalies,
especially in the Beale Lake area. At the Nizi showing, historical channel samples of the
Discovery vein returned the following selected near-surface high-grade values: 27.09
grams per tonne gold and 1,220.6 grams per tonne per tonne silver over two metres;
15.09 grams per tonne gold and 1,073.2 grams per tonne silver over 3.5 metres and 8.91
grams per tonne gold and 596.6 grams per tonne silver over one metre (British Columbia
Geological Branch Assessment Report 22840). Strong bismuth and tungsten anomalies
are noted in the Major Hart anomaly cluster.
The contact of the pluton with the Slide Mountain ultramafic rocks may have ophilite-
hosted gold potential.
There may be emerald potential where volatile flux-rich fluids may have mixed with
chrome-rich rocks. Emeralds are known in the Yukon in a similar environment.
Beryllium has never been analysed for in the Major hart area.
The area of the three-way contact with Slide Mountain ultramafics, Slide Mountain
volcanics and sediments, and the Major Hart Pluton likely has the strongest structural
preparation for the development of lode ore zones. Air photo analysis shows parallel
(bedded) structures in the area mapped as volcanics, at the contact.
The emplacement of the pluton is contemporaneous with up to 450 km of dextral
movement along the northwest trending Ketichka Fault. The outlying dykes to the
northwest, regional northwest trending faults, northwest alignment of host rock contacts,
and northwest position of correlated volcanics (Nizi) suggest a possible northwest
position of the apex of the Major Hart Pluton is likely. This may have resulted in the bulk
of the roof of the pluton being preserved at present. The roof of a specialty granite
intrusion is where the highest degree of concentration of volatile and incompatible
elements is concentrated during emplacement. Tin griesens, pegmatites, rare elements,
and rare earth element concentrations are most commonly located in the immediate
vicinity of the apex and thermal areole of the most fractionated granites.
The anomalous area is currently 95% contained within the claim area. The main area of
interest is 100% contained within mineral claims held by the joint owners, not a
checkerboard of disparate owners and interests.
The Major Hart Property is the most likely place in B.C. to host a brand new discovery of
real significance, in our opinion. This is not a promotional gimmick, a tag-on play, or
closeology maybe. This is the real deal, with real potential for something really big,
really new and truly different from the rest of properties out there currently. It is a freak
of nature…… and that is what mines are made of.
