HOUSTON (ICIS)--Great Quest Metals has entered into an agreement with Botswana Ash to develop the Sua Pan brownfield potash project in southern Africa, the Canadian fertilizer developer announced on Wednesday.
Company officials said the arrangement with Botswana Ash centres on developing the potash brine potential of Sua Pan in Botswana. Great Quest said that significant concentrations of potash and potassium sulphate have been recorded in the brines of Sua Pan but have never been recovered commercially. The company will begin a programme to evaluate the economic potential of potash recovery from the native brines, the mine effluent and the historical mine tailings.
The Sua Pan is the largest and lowest of three salt pans in the Makgadikgadi Pans region of northeastern Botswana and is considered one of the largest salt flats in the world. Previous research in the area by the World Bank suggests that the Sua Pan has the capability of producing 163,000 tons/year (148,000 tonnes/year) of potash.
Botswana Ash has granted Great Quest a one-year exclusivity with an option to extend for another year to explore the potash potential. Officials said once Great Quest has determined the extent of the potash deposits in the Sua Pan, it intends to enter into a long-term agreement that would provide compensation for infrastructure and potash resources.Great Quest’s flagship asset is the Tilemsi phosphate project in northeastern Mali, which contains high-quality phosphate resources.
