Saskatchewan is host to a large mining industry. The province is the world's largest producer of potash (8.5 million tonnes per year or 35% of world demand) and uranium (10.8 million kg per year or 30% of the world's production). In Canada, it is also the third largest producer of coal (11.6 million tonnes per year and reserves of 30 billion tonnes). There are also deposits of precious and base metals, diamonds, clay, bentonite, silica sand, salt, potassium sulphate, sodium sulphate, copper/zinc, and peat. The discovery of kimberlite pipes and diamonds in Saskatchewan has led to extensive exploration and drilling by more than 30 companies.
Saskatchewan is the third-largest, non-fuel, mineral-producing province in Canada. Total mineral sales in 2002 were $2.4 billion-about 8% of the provincial Gross Domestic Product (GDP). The industry creates some 6,000 direct and 12,000 indirect jobs.
