This document details the costs incurred to heap leach gold ore tailings

1. PROJECT FINANCIAL REQUIREMENTS TO HEAP LEACH 50,000 METRIC TONS OF
GOLD ORE TAILINGS IN KARAMOJA (MORUITA) TO RECOVER AN ESTIMATED 90
KILOGRAMS OF GOLD

2. EXECUTIVE SUMMARY
The project is located in Nakapiripirit District in Uganda. Specifically in Moruita Sub-county, Acherer
village.
The intention is to heap leach 50,000 tons of gold rich tailings with an average yield of 1.8 – 2.5 grams
per ton. This will yield approximately 90 kilograms of gold with a value of about $5,400,000.
The project will be divided in phases of leaching cycles for cost management.
Each leaching cycle will have 5,000 tons, with a target of 9-10 kilograms of gold. The financial
requirements can be broken down into the leaching cycles.
HEAP LEACHING
Heap leaching is a process through which metals are extracted from the ore in which they are found. Heap
leaching is often chosen for its efficiency and cost-effectiveness. As the need for resources increase, the
heap leaching industry has risen to the occasion with advancements creating an even more efficient leach.
One of which, is the process of agglomerating the ore prior to the leach.
In gold extraction technologies, the gold heap leaching process flow has been widely used because of
its simple process, low energy consumption, less equipment configuration, low capital construction
investment, and production cost, which is especially suitable for treating low-grade gold ore.
In production, the common gold heap leaching process flow mainly includes six stages: ore preparation,
leaching pad construction, heap building, leaching solution preparation, solution distribution and
collection, rich solution (precious solution) processing.
1. Ore preparation
The ore preparation stage mainly includes crushing, granulation, and pretreatment operations, whose
purpose is to improve the ore leachability and leaching pile permeability, avoid liquid flow irregularity,

3. blockage, ditch flow, and other phenomena, improve the recovery rate of gold ore and reduce the
consumption of leaching solution.
Crushing
Different crushing processes are carried out according to the ore properties and technological
requirements. The waste ore generally doesn’t need crushing (30%), the ore particle size after two-stage
crushing is 30-50mm (53%), and the ore particle size after three-stage crushing is 9-19mm (17%). It has
been proved that crushing is one of the key technical links to ensure the good permeability of ore and
improve the leaching rate of gold ore.
Granulation
The granulation is required first for the fine ore and high clay containing ore. Adding a certain amount
(3-6kg/t) of cement and lime adhesive to the ore, then adding an appropriate amount of sodium cyanide
solution, keeping the ore 8-12% of humidity, curing 8-12h, thus forming the ore group. The granulation
treatment improves the permeability of the ore heap, keeps the sufficient oxygen supply, dissolves the
gold by cyanide in advance, and greatly improves the gold leaching rate.
This process often uses a cylinder granulator, disc granulator, multi-section belt granulator.
Among them, the belt granulator can directly send the fine ore after the granulation to the heap leaching
field, while the cylinder granulator is especially suitable for the high clay-containing ore.
Pre-treatment
In the granulation process, sometimes it is necessary to add a leaching solution to pretreat the ore, whose
purpose is to improve the permeability of the leaching heap and the leaching rate of useful components
of the ore.
2. Leaching pad construction
In order to collect the rich liquid and prevent the leakage of the solution, the bottom of the yard should
be repaired and bedding before the heap building. The materials used in the construction of the leaching
pads are clay, sand, gravel, asphalt, reinforced concrete, plastic film, or rubber plastic plate. Depending
on the different materials, the thickness of the cushion layer is generally 300-600mm. The longitudinal
and transverse drainage ditches are paved with block ore in the cushion layer, and then a layer of large
ore is laid on the whole bottom plate to protect the bottom pad.
3. Heap building
The purpose of heap building is to make the ore pile have good and uniform permeability, and ensure
that the slope will not collapse. The height of the ore heap mainly depends on the permeability of the ore
heap, the content of the leaching agent in the leaching solution, the equipment, and the method used in
heap building.
Generally, the heap height is 3-9m, and the heap of raw ore can be as high as 46m. There are many ways
to build the heap, such as the multi-heap method, multi-layer method, slope method. Most of the gold
heap leaching plants often use cars, front-end loaders, bulldozers to unload ore to build the heap, and
timely loosen the heap.
4. Leaching solution preparation
The leaching solution used for leaching the useful components from gold ore is prepared with water and
leaching agent according to a certain formula. The common leaching agents include sulfuric acid, nitric
acid, hydrochloric acid, sodium carbonate, sodium bicarbonate, ammonium carbonate, ammonium

4. bicarbonate, ferric sulfate, chloride, sodium iodide, potassium iodide, ammonium sulfate, air, oxygen,
permanganate, nitrogen oxides, hydrogen peroxide, and chlorate. The formula and dosage of the leaching
solution need to be determined according to mineral species, mineral composition, and chemical
composition. Generally, the alkaline sodium cyanide solution is used in the gold heap leaching.
5. Solution distribution and collection
The solution distribution is to evenly spray the leaching solution on the top surface of the ore heap, and
the solution distribution system is composed of a liquid distribution pool, pump, infusion pipe and spray
pipe and spray device laid on the ore heap.
Take spray as an example, the spray pipe network uses high-strength polyethylene plastic pipe, the spray
head uses the rotary swing sprinkler head with a wide spray radius, large and uniform spray droplets,
which is not easy to atomize, and convenient to install.
In the spraying process, one is to make the leaching solution evenly sprayed on the ore heap, another is
to achieve the required spraying intensity, that is, the amount of spraying per unit area in unit time,
usually 0.1-0.4L/m•min, the spraying time accounts for about 1/3 to 1/2 of the total time. After spraying,
the rich solution from the bottom of the heap enters the solution collecting tank through the solution
ditch and then is pumped to the workshop.
6. Rich solution (precious solution) processing
The gold is extracted by carbon adsorption and desorption electrolysis (or zinc dust replacement
precipitation). The activated carbon becomes the gold-loaded carbon due to the absorption of gold in the
pulp. After the completion of the adsorption operation, the gold carbon-containing pulp is sent to the
carbon screen through the air lifter to separate the pulp and activated carbon. After screening and
washing, the pulp is sent to desorption and electrolytic operation.
Under the high temperature and high pressure, the anions easily adsorbed by activated carbon are added
to the desorption system, and Au(CN)2- is replaced to obtain gold slime and carbon poor, so as to realize
the desorption of gold. The precious liquid obtained by desorption of gold-bearing carbon is recovered
by ionization to obtain the solid gold.

produced is questioned and, after investigation, a determination made as to its validity. Nesch Mintech
has professional experience and a common sense approach to quality control for ensuring that only
quality data is released. The dual foundations of the laboratory quality control program is its internal
quality control, composed of day-to-day and sample-set to sample-set monitoring of analytical
performance, and its external QC, based on the laboratory’s performance in proficiency testing
programs. The QC data generated is recorded in such a manner to detect trends.
QC schemes utilized for Nesch Mintech Laboratory consist of:
a) Reference material (CRMs) or Quality control samples
b) Use of alternative instrumentation that has been calibrated to provide traceable results;
c) Functional check(s) of measuring and testing equipment;
d) Use of check or working standards with control charts, where applicable;
e) Intermediate checks on measuring equipment;
f) Replicate and duplicate tests or calibrations using the same or different methods;
g) Retesting of retained items;
h) Correlation of results for different characteristics of an item;
j) Intra-laboratory and interlaboratory comparisons;
k) Testing of blind sample(s) and blanks.
l) Retained samples are subjected to repeat testing for a single sample in each batch of 50 samples after
every 1 month for 3 months to monitor the performance of the laboratory tests with time

16. 9
m) Nesch Mintech laboratory monitors its performance by comparison with results of other laboratories,
where available and appropriate. This monitoring is planned and reviewed and include, but not limited
to, either or both of the following:
- Participation in proficiency testing and Participation in interlaboratory comparisons.
n) Data from monitoring activities shall be analysed, used to control and, if applicable, improve Nesch
Mintech laboratory’s activities. If the results of the analysis of data from monitoring activities are found
to be outside pre-defined criteria, appropriate action shall be taken to prevent incorrect results from
being reported.

32. JIN CHAN - Patented Metallic Ore Dressing Agent
Instructions of JIN CHAN Metallic Ore Dressing Agent
I. Introduction to JIN CHAN
1. Scope of application:
① Applicable ore types: gold and silver ore, cyanidation slag, gold concentrate, pyrite cinder, lead and zinc
cinder, anode mud and other materials containing gold and silver.
② Applicable beneficiation process: dump leaching, pool leaching and CIP process, etc.
2. Product form: Granular or powder form.
3. Dissolution: It can be used after being fully dissolved in water by full stirring under normal temperature. The
concentration of this agent should be 10% to 20%.
4. pH value of pulp or solution: The pH value is usually adjusted with lime or caustic soda to 10.5 to 11.5.
5. Dosage:
① It is recommended to determine the agent consumption and concentration at the leaching rate under the
optimum conditions through the beneficiation test. The agent should be added according to test results during
production on site.
② For easy-to-leach ore, refer to the original dosing system for sodium cyanide.
6. Product use: in accordance with the conventional cyaniding process.
7. Others:
1 JIN CHAN has the best effects at the normal temperature, but it should not be used at a temperature below
10℃.
2. It is recommended to regularly test the gold content of pregnant and barren solution, as well as the pH value of
solution or pulp and JIN CHAN concentration.
3. Hydrogen peroxide, potassium permanganate and other strong oxidants are not recommended to be mixed
with JIN CHAN (pretreatment is allowed), to prevent the consumption of part of JNCHAN.
4. The use of ammonia, sodium sulfide, potassium ferricyanide, lead nitrate and other chemical agents in
complex ore pretreatment has little impact on JIN CHAN gold leaching.
5. A little of black insoluble slag generated after dissolution of JIN CHAN will not affect the reagent use.
6. JIN CHAN has no adverse impact on gold and silver leaching when mixed with sodium cyanide.
7. “Rich-oxygen leaching” in the CIP (carbon-in-pulp) process may have adverse impact on leaching with JIN
CHAN.
8. The unpacked or damaged reagent must be used up as soon as possible, in order to prevent failure due to
exposure to air.
II. Test of JIN CHAN concentration in leaching solution
1. Vessels and reagents: one 1,000ml brown glass flask, one 100ml brown dropping glass, one 100ml beaker,
one 25ml brown burette, one 10ml pipette, one suction bulb; propanone and distilled water.
2. Reagent preparation: (reagents shall be stored in brown glass bottles to avoid heat and light)
① Indicator: put a whole bottle of red reagent (sample A) into 100ml acetone solution, then shift it into 100ml
brown dropping glass, and keep this reagent sealed without exposure to light.
② Test reagent: put a whole bottle of white reagent (sample B) into 100ml distilled water till it is fully dissolved,
shift it into the 1,000ml brown glass flask, add distilled water to 1,000ml, shake the solution, and keep this reagent
sealed without exposure to light.
3. Operating steps:
1) Use the 10 ml pipette to adsorb 10ml JIN CHAN solution to be tested, put it into the 100ml conical flask, add

33. JIN CHAN - Patented Metallic Ore Dressing Agent
5 drops of indicator, and shake the solution up (till it turns yellow).
2) Carry out titration with the test agent via the brown burette, shake the bottle up while dropping. At the same
time, observe the color change until the solution turns from yellow to light red. Read the consumption V (ml)
of the test agent.
3) Calculation: JIN CHAN concentration (‰) = 0.33 × V
(Example: If the consumption of the test agent is 0.5ml, the JIN CHAN concentration of the solution under test
is 0.165‰.)
4. Precautions for product transportation, storage and use:
1. Main components of JIN CHAN series of environmentally friendly and efficient gold leaching agents include
carbonized sodium cyanate, alkaline thiourea, alkaline salt and other mixtures. It has been identified as an
environmentally friendly gold leaching agent by third-party test agencies, and can be used for extraction of gold,
silver and other precious metals.
2. This product must not be used for illegal exploitation of minerals or recycling of mineral resources and
precious metals without approvals of authorities.
