A barytes mining lease spanning 316 acres for exploration of barytes in Gunga near Khuzdar, originally hosting proven reserves of 1.28 million tonnes, was granted to BME by GoB in 1974. The lease is valid up to 2033. With recent drilling in the area, indicated reserves of over 40 million tonnes have been established.
BME operates two grinding mills for barytes with the total production capacity to 70, 000 - 80,000 metric tonnes barytes annually in line with the specifications of the American Petroleum Institute. In view of the increasing local and export demand, BME has recently completed installation and commissioning of a third grinding mill which will increase the grinding capacity to 135,000 – 150,000 metric tonnes.
Over the years, BME has met nearly 90 percent of the barytes requirement of the oil and gas exploration industry in Pakistan. Besides PPL, the major customers of barytes are Oil and Gas Development Company Limited, Pakistan Oil Fields Limited, Mari Petroleum Company Limited, Scomi Oil tools (formerly known as KMC Oil tools), M-I SWACO (Pakistan) and Baker Hughes Incorporated. BME also exports barytes powder and lumps/ ore to the international market, mainly covering Gulf Cooperation Council countries and saving foriegn exchange for the country.
