MINERAL DEPOSITS FOR EXPLOITATION

Iron Ore Deposits Of Chagai-Magmatic Arc (Zone 11)

The Magnetite/hematite deposit of Chilgazhi (290-08? N:640 14? E), and Pachin- Koh and Chigandekin andesitic Sinjranivolcanics, are massive to disseminated and or layered or plugs. Chilgazhi with 23 million tonne resources carries 33%Fe, 0.39% Cu. and 208 g/tone Au., whereas Pachinkoh Chigandek having 30.0 m tonne proved and 40.0 m tonne resouce have 67-82 % Fe2O3. Other smaller deposits also exist in this zone.

Iron Ore in Sedimentary Fold Belt (ZONE-3)

This category includes the 350.0 million tonne reserves of Kalabagh-Chichali Cretaceous Chamositic and glauconite-sedirite ore in Punjab and the 166 million tonne resources of Pezu and Nizampur (NWFP). The ore on average has 33-35% iron. The sedimentary fold belt also carries 200.0 million tonne of hematitic ore (30-45% Fe) at Dilband-Kalat, Balochistan. Fairly developed infrastructure facilities exist in all these areas.

Gypsum/Anhydrite in the Foreland Sedimentary Fold Belt (Zone-3)

Over billions tonne inexhaustible measured reserves of gypsum anhydrite with 30-40% CaO occur at numerous areas in Northwest Frontier Province/Federally Administrated Frontier Regions, Punjab, Sindh and Balochistan. These areas have fairly developed infrastructure such as roads and power.

Soft Decorative Stones (Marble etc)

Pakistan is known for onyx which is exported. Other marble deposits of different attractive colours, shades and fabric exist in inexhaustible quantities in North West FrontierProvince, the Northern areas, Azad Jummu Kashmir, Federally Administrated Tribal Area, Balochistan and some parts of northern Punjab. White, whitish-gray black-silky, Jet-black, pink, grayish-green, black-zebra, green-zebra, camel and cream colour verities are being mined and marketed locally. A tremendous potential exists for insitu block mining, precision sizing/processing for marketing abroad.

Hard Decorative Stones (Granites etc)

 

The mighty ranges of Himalaya and KaraKoram and their off shoots provide heavens for huge batholith and stock size deposits of granites and basalts etc. of decorative nature. Varities include black, olive green, greenish grey, salt-pepper and white granites in Swat (NWFP), Balochistan and Nagar Parker in Sind. Fair infrastructure is available to most of the areas of interest. Scientific block mining and processing is negligible in Pakistan.

Coal

Geological investigations have shown 185 billion tonne of measured coal reserves in zone 2,3,&5 in Pakistan of which more than 184 billion tonne deposits are located in SindhProvince, with Thar coal field being the largest,followed by Thatta-Sonda, Lakhra and Jhimpir. The coal is lignite to lignite-A to sub bituminous B&C in character with an average heating value of 6000 BTU/lb. The huge deposits warrant investment for use of coal in Power Generation and preparation of clean fuel products.

Rock Salt

The Foreland Sedimentary Fold Belt, (Zone-3) carries inexhaustible deposits of rock salt. The base of the deposits could not be known even after drilling for over 4000 meters.On surface, the deposits extend from North West Frontier Province to the Punjab Province. The salt can meet requirements of all sorts of salt-based chemical industries to any extent and size.

Gemstones

Gemstones occur in northern part of the country. Out of 25 precious and semi precious stones and mineral specimens, 7 are intermittently exploited and marketed all over the world. These are emerald of Swat, rubies of AJK and Hunza-Ishkoman, Gilgit, Pink-Topaz of Katlang-Mardan, aquamarine and tourmaline of Gilgit and Chitral, peridot of Kohistan and Pargasite of Hunza.

All these gems have beautiful attractive colours, excellent crystal clarity and a range of size/weight meeting any international standard. Tremendous potential exists for investment in the subject of scientific mining and cutting/polishing for value addition of gemstone from the known localities and exploration for further findings.

 

Kashmir and Hunza Gilgit Ruby

Occurring in the Gondwanic Domain (Zone-4), the Ruby deposits of AJK are located in Nangimali? Khora? Katha, Chitta Ratta and Naril nala in Neelum valley. It is associated with calcite veins in recrystalized limestone. It is transparent to translucent and brownish pink to pinkish-red and deep red in colour. The deposit is being mined and the potential resources are estimated at about 24.9 million grams.

Ruby of Hunza, Gilgit have a slight touch of Pinkish hue. The main ruby deposits occur in a dolomitic marble belt extending for over 100 km from Hunza valley to Ishkoman, close to the main Karakorum thrust.

Topaz of Mardan & Dassu-Skardu.

Pink to red and colourless toapaz are located in the Gondwanic Domain (Zone-4) in Mardan and Skardu respectively. Topaz bearing pegmatites are largely found at, 1) Bulechi (350.41/ N., 740.48/ - 35/) 2) Shirngus (350- 23/N 750- 31/Eand 3) Gone (350- 41/ N 750- 31/ E ) near Dassu in the Skardu area Northern Pakistan.

Emerald deposits of Swat
Mingora deposits

These are emplaced in ophiolite of Gondwanic Domain (Zone-4). The best-known deposits located at Mingora, Malakand Division) 160 km north east of Peshawar. Emerald occurs in Ophiolitic melange, which is composed of highly tectonised faulted blocks. The Swat deposits are producing excellent quality gems, described by Gubelin(1968, 1982) as being some of the finest emeralds in the world. The stones have become famous for their brilliance, medium to deep green colour and unique transparency. These are comparable to the finest Colombian specimens from Muzo (Gubelin, 1968). In the belt emeralds have been discovered at Gujar Kili and Shamozai areas.

Tourmaline and Peridote of Northern areas

Gem quality tourmaline is found in the Kohistan magmatic arc (Zone-6) at Haraosh near Gilgit, Stak Nala (between Gilgit and Skardu), Bulecli and Shingus (Gilgit division) and Garm Chashma in Chitral.

Tourmaline at Haraosh are pink, blue, and green varieties. The Stak Nala is now famous for bicolour and tricolour tourmaline. Gem grade tourmaline also occurs at Buleclhi and Shingus (Gilgit division). Indicolite (blue tourmaline) is found in pegmatite of Garm Chashma (Chitral). Green tourmaline has also been found in pegmatites of Donga Nar in Azad Kashmir.

Peridote of Indus Kohistan is one of the most beautiful gemstones of Pakistan and is sporadically being mined at different localities. It has already captured market both locally and abroad.

Others

Emeralds also occur at Gandao ofMohmand Agency and Amankot, Mor Darra, Barang of Bajaur agency, Makhad and Charbagh in Swat district and Khaltaro, Gilgit. These deposits, except Charbagh and Makhad, have not been explored as yet.
