StockMarketWire.com - The directors of Salt Lake Potash advised that a number of recent exploration licence applications took its total holdings in the Goldfields mining district in Western Australia to a total of 9 complete or partial salt lake playas. All featured proximity to vital infrastructure - the Goldfields Highway, the Kalgoorlie-Leonora rail line and the Goldfields Gas Pipeline. The combined SOP projects comprised over 4,750km² of exploration permits and applications. Collectively these lakes formed its Sulphate of Potash (SOP) project, which will be known as the Goldfields Salt Lakes project. All lakes within the project were at least 200km² each in surface area with a large, flat and relatively bare surface playa for potential evaporation pond construction. Initial focus of the Goldfields Salt Lakes project was on Lake Wells, which had a playa surface of approximately 440km². The scoping study in August 2016 highlighted the outstanding potential economics of extracting hypersaline brine by trenches AND bores for solar evaporation of salts and processing to produce premium SOP. It indicated Lake Wells would be firmly in the lowest cost quartile for any SOP Project in Australia and around the world, with relatively low transport costs being a major advantage. While proceeding with a pre-feasibility study (PFS) for Lake Wells, the company also begun exploring other lakes in the Goldfields Salt Lakes project, starting with Lake Irwin and Lake Ballard. Initial evaporation trials of brines from these lakes indicated they are suitable for production of potassium and magnesium sulphate salts for processing into SOP as well as potentially valuable co-products. To date, only reconnaissance work was undertaken on the other six lakes in the project and comprehensive surface brine sampling and initial exploration was planned for each of them over the course of this year.
