Sua Pan Brownfield Potash Project
Great Quest's Sua Pan Potash Project is located at Sua Pan, approximately 180 km from Francistown in northern Botswana. The company has the exclusive right to explore and develop the potash potential of the Sua Pan operations of Botswana Ash Corporation and is advancing towards a definitive agreement.
The Sua Pan Salar is the largest and lowest in elevation of three salt pans in the Makgadikgadi Pans region of northeastern Botswana. It is considered one of the largest salt flats in the world and has a surface area of approximately 4,900 km2 at an elevation of 890 m above sea level.
Historical work published by the World Bank suggests that the Sua Pan Salar was capable of producing 163,000 tons per year ("tpy") of potash mainly KCl (Wold Bank/SADC, 1993 Fertilizer Supply Options Model), including potential to produce 21,000 tpy of K2SO4 (World Bank/SADC, 1991, An Action Plan for the Development of Fertilizer Industry).
Botswana Ash (Pty) Ltd ("BotAsh") began operations in April 1991. The Company produces soda ash and salt. The primary market for soda ash is South Africa, where most of the product is used in the glass industry. The nameplate production capacity of the soda ash plant is 300,000 tpy. The facility also produces fine and coarse salt with a production capacity of 650,000 tpy. The mine is connected to South Africa by rail operated by Botswana Railways. BotAsh is a 50/50 joint venture between the Botswana Government and managing partner Chlor Alkali Holdings (CAH) Group of South Africa.
KCl concentrations in bitterns are reported to exceed 10.9 grams per litre (g/L), more than 100% improvement over the native brine concentration of 4.3 g/L as measured by BotAsh. This compares favorably with potash concentration in the brine from the Dead Sea of 6.2 g/L. These results have not been independently verified.
Brine projects have some of the lowest operating and capital costs in the world. Great Quest would leverage the existing infrastructure reducing the potential capital expenditure. The potential plant would also function as an additional circuit on the existing BotAsh operation.
