Goldfields Salt Lakes Project

Salt Lake Potash is developing a series of primary Sulphate of Potash (SOP) operations across the West Australian goldfields.

The Company plans to produce premium SOP from extracting hypersaline brine from salt lakes, transporting the brine in a series of solar evaporation ponds to produce potassium-rich harvest salts which can then be converted in SOP for the domestic and international markets.

SOP is the premium source of potassium favoured by high value, chloride intolerant crops.

Initial development efforts are focused on the Lake Way project which is now substantially progressed, with first sales expected in the first quarter of 2021. Over the long-term the company plans to develop an integrated SOP operation, producing from a number of lakes within the GSLP.

Lake Way Project

The Lake Way project is located in the Goldfields region of Western Australia, 15km south of Wiluna. The Wiluna region is a historic mining precinct dating back to the late 19th century and is serviced by well developed, high quality infrastructure (airport, gas pipeline, sealed road).

The Lake Way BFS released in October 2019 highlighted an operation that could produce 245kt of SOP for capital expenditure of $256m and with operating costs of A$302/t, placing it at the bottom of the 1st quartile of global SOP operations.

Construction of the Lake Way evaporation pond network and brine abstraction trenches commenced in Q1’2019 and the project is now substantially progressed with first revenues expected in the first quarter of 2020.

Lake Ballard and Lake Marmion

Lake Ballard and Lake Marmion sit at an intersection of the Goldfields Highway, the Menzies-Leonora railway line and the Goldfields gas pipeline.

Resource definition work is currently underway at both lakes. This process will form part of a strategic review to prioritise future developments.

Lake Wells

The Lake Wells Project is located in the Northern Goldfields of Western Australia approximately 200 km north of Laverton. The area is well served by existing infrastructure, including the Great Central Road, the Goldfields Highway, the Goldfields Gas Pipeline and the railway sidings at Malcolm and Leonora.

SO4 completed a Scoping Study at Lake Wells in 2016 which confirmed the potential of the Project to produce low cost SOP by solar evaporation of lake brines.
