Lead and Zinc are also among main minerals. Common minerals of economic significance are Galena (PbS) and Sphelerite (Zn, Fe). Some of the important Lead Zinc prospects of District Khuzdar require detailed exploration. Gunga Lead Zinc Barite has deposit of 10 million tones according to preliminary estimates (Geological Survey of Pakistan) wheres Surmai Lead Zinc deposit are estimated at 3 million tons Iron Ore deposits of Hematite are of economic significance at different localities in ultramafic rocks near Monar Talar. These deposits are being mined by private sector and transported down the country in raw form. Strontium and Copper deposits of good quality have been reported too. The Barite mineral in chemical composition of BaSo4 owing to its high specific gravity is used in production of oil well drilling mud, in paints, chemical ceramics, paper industries and manufacture of barium chemicals. Its large deposits occur at Gunga 16 Km to south-east of Khuzdar city with ore in interbedded limestone and shale. The zone of mineralization is about 1,380 meters long. Massive Sulphide Copper deposits are also found in the area 88 Economic Activities and Livelihood Patterns in the Project area ................... 88 Traditional Water Rights and Management .................................................. 89 7 POTENTIAL IMPACTS AND MITIGATION MEASURES ....................................
