COPPER ORE RESERVES OF PAKISTAN
Pakistan lies on a massive transcontinental geological feature that runs through the
earth's crust from Eastern Europe right across to Mongolia. It is known as the Tethyan
Magmatic Arc. A Magmatic arc occurs in areas where earth's tectonic plates collide or
sub duct with each other and are often areas of intense volcanic activity. When
continental plates collide in this way, they form major mountain systems such as the
Himalayas, the Alps and the Andes. But what makes Magmatic arcs so special is the
ore deposits found within them —deposits of copper and gold.
Credible international surveys indicate the wealth of resources and suggest that the
area is home to one of the biggest copper reserves in the world with over 2 billion Tons
of copper and 21 million ounces of gold.
Moreover it as also believed, on the basis of surveys carried out by FATA authorities,
that the copper ore reserves in Waziristan are even more than those explored in
Reko Diq, but are not being explored yet due to political reasons.
TYPES OF COPPER DEPOSITS:
VMS (Volcanogenic Massive Sulfide )
Copper occurs in veins, vein lets, fractures and also in disseminated form.
Have high grade but low tonnage.
Copper ore grade ranges from 0.3% to 10%.
Copper deposit of Oman, Cyprus, Bay of Iseland complex are the
examples of this type.
Porphyries
Porphyries are a specific type of ore deposit found at the tip of sub-
ductive arcs all over the world.
They are very large, low-grade deposits with a very high tonnage
and normally contain copper, gold, tin, tungsten and molybdenum.
Copper ore is disseminated in the host rocks.
Ore grade generally ranges between 0.2% - 1%.
Most of the world's copper comes from such deposits located
primarily in South America, New Guinea, Indonesia, the United States,
and Canada.
COPPER ORE IN PAKISTAN
1. SAINDAK-BALOCHISTAN
The discovery of copper deposits at Saindak was made in the 1970s in collaboration
with a Chinese engineering firm. The Saindak Copper-Gold Project was set up by
Saindak Metals Ltd, a company wholly owned by the government of Pakistan, by the
end of 1995 at a cost of Rs.13.5 billion
Location
Saindak Copper-Gold Mine is located in Saindak town,
District Chagai Balochistan, Pakistan.
The mineralized area is easily accessible through fair weather roads
Mineralogy
The Saindak ore contains on average 0.5 gram of gold per tone and 1.5 grams of
silver per tone.
Reserves
The Saindak project was based on estimated ore reserves of 412 million tones.
The mine is reported to have produced about 50,000 tones since October 2003.
According to official estimates, the project has the capacity to produce 15,800
tones of blister copper annually, containing 1.5 tones of gold and 2.8 tones
of silver.

2. REKO DIQ – BALOCHISTAN
The Tethyan Magmatic Arc is one of the least explored of the world's major copper
belts. Pakistan lies on this copper belt, which runs through Baluchistan’s 'tail end' —
an area which is also unfairly known in the West as 'The Devil's Triangle' as its three
sides border Iran, Afghanistan and Pakistan.
Reko Diq literally means "sandy hill" in Balochi. It is actually an ancient volcano that
has eroded over time to form a few low hills that lie in a roughly circular shape and is
approximately 10km in diameter.
LOCATION OF REKO DIQ
Reko Diq is a remote location in the North-West of Chagai district. Chagai is a
sparsely populated western desert province of Balochistan. It is mostly low relief
and thinly populated desert. The weather of Chagai ranges from very hot
summers of 40-50°C to very cool winters of up to -10°C with less than 40 mm
precipitation (winter rain and minor snow). It also exhibits periods of high wind
and dust/sand storms which have a demobilizing impact on the local activities
and trade. Access to the Chagai district is via the Zahidan - Quetta highway also
known as the London Road.
The Reko Diq area is part of the Tethyan Magmatic Arc, extending through
central and southeast Europe ( Hungary, Romania, Bulgaria, Greece) Turkey,
Iran and Pakistan through the Himalayan region into Myanmar, Malaysia,
Indonesia and Papua New Guinea. It contains wealth of large copper-gold ore
deposits of varying grades.
The eastern and central sections of the belt are well recognized hosting world
class mineralization such as Grasberg, Batu Hijau in Indonesia, Ok Tedi in
Papua New Guinea and Sar Cheshmeh in Iran. Whereas in the eastern Europe it
host world class porphyry/epithermal cluster of Bor, Majdanpek in Serbia and
more recent developments include Skouries and Olympias Greece, and Copler in
Turkey.
Reko Diq area is one of many eroded remnant volcanic centers in the Chagai
volcanic chain of mountains which runs in an east west line across Balochistan
between the Quetta to Taftan railway and the border with Afghanistan. GOP has
identified a large low grade copper-gold resource at Reko Diq.
REKO DIQ RESOURCE
The project has an estimated mine life of 56 years. A large low-grade copper
porphyry deposit, Reko Diq has total mineral resources of 5.9 billion tons of ore
with an average copper grade of 0.41 per cent and gold grade of 0.22 g/ton. It
contains 28-31% copper and 7-22 g/ton gold The economically mine able portion
of the deposit has been calculated at 2.2 billion tons, with an average copper
grade of 0.53 per cent and gold grade of 0.30 g/ton. The annual production is
estimated at 200,000 tons of copper and 250,000 ounces of gold contained in
600,000 tons of concentrate. In order to achieve this production rate
approximately 110,000 tons of ore shall be processed daily
According to the extensive technical and financial studies undertaken, in order to secure
optimal economies of scale efficiencies, and lower mining and processing costs, a large
scale, state of the art mining and processing unit is required at Reko Diq.
MINING PROJECT
CURRENT STATUS OF REKO DIQ PROJECT
GOP has completed an extensive exploration program at Reko Diq with more than
300,000meters drilling comprising mainly diamond and reverse circulation drilling. A
bankable Feasibility Report based on extensive world class engineering, technical and
financial studies has been finalized. Environmental and Social Impact Assessment
(ESIA) report is also in final stages.
FUTURE DEVELOPMENTS: SETUP OF MINING OPERATIONS
The next steps to advance the project will be taken by GOP as soon the mining lease is
granted, followed by project financing and construction of ancillary infrastructure to
make the mine operational.
The GOP Reko Diq Project shall consist of 4 main operations components:
1. An open-pit mine.
2. A processing facility..
3. A concentrate pipeline to transport the product from the mine site to the port of
Gwadar, and a dedicated marine terminal facility at the port for storage and
transfer to shipping vessels for supply to smelters throughout the world..
4. A project village for employees.
MINING TECHNIQUE USED
The mining operation at Reko Diq is modeled on an open pit mine utilizing a
conventional truck and shovel technique. This means that giant mechanical shovels
shall be used to dig out the copper ore which shall then be loaded onto 360 ton trucks
that will then haul tons of copper ore on a daily basis from the mine to the processing
facility. At the processing facility the rocks (ore) shall be crushed in giant crushers. This
crushed ore shall then be transferred to a fine-grinding stage where it will be converted
into a powdered form. This powder, containing small quantities of copper and gold shall
pass through a separation process called flotation, resulting in 30% concentrated slurry
of copper and traces of gold.
This concentrate is the final product of the Reko Diq Mining Project which shall then be
transported for further processing to extraction & smelting units.
MINING TECHNOLOGY DEPLOYED
The Reko Diq mine will employ state-of-the-art mining equipment, support systems and
maintenance practices. To operate this project latest technological innovation will be
introduced, putting the Reko Diq project at the cutting edge of technology. This will
include360 tons haul truck equipped with computer controlled engine management
systems, and the Reko Diq process plant will be one of the only few hard-rock mines in
the world to apply High Pressure Grinding Rolls (HPGR) between crushing and milling.
Use of latest technology is critical to create efficiencies in the processes to make Reko
Diq a long term economically viable project.
TRAINING AND TECHNOLOGY TRANSFER
Significant skill and technology transfer shall take place during the life of the mine in
Balochistan. GOP is committed to skill development and training of local employees to
ensure that indigenous capabilities develop along with the technology transfer. GOP
has on-site training programs for its employees and off-site training opportunities are
provided within training institutes in Pakistan and also abroad. GOP has an integrated
training program comprising a basic skills development module and a specialist
vocational training module.
