Salt Lake Potash produces premium sulphate of potash product in Lake Way tests

Test results support the company’s marketing strategy to supply into the premium SOP market.

Salt Lake Potash Ltd - Salt Lake Potash completes pilot plant test work on Lake Way salts at Saskatchewan Research Council
The Lake Way bankable feasibility study (BFS) is scheduled for completion in early October

Salt Lake Potash Ltd's (ASX:SO4) pilot plant test work on salts from the Lake Way project has confirmed a highly water-soluble premium sulphate of potash (SOP) product with a potassium oxide grade exceeding 53%.

The pilot plant operation was conducted by the Saskatchewan Research Council (SRC) over two separate trials utilising 5 tonnes of salt harvested from the Lake Way project in the Goldfields region of Western Australia.

The process flowsheet confirms that the addition of potassium chloride provides an increase in the SOP output from equivalent Lake Way brine volumes with no material additional capital expenditure.

The total solubility and dissolution rate indicate that the product would be suitable for application in drip irrigation systems.

“Outstanding results”

SO4's chief executive officer Tony Swiericzuk said: “The outstanding results from the pilot plant test-work confirm the addition of potassium chloride into the process will enable Salt Lake Potash to utilise the excess sulphate within the Lake Way brine to produce additional premium-grade SOP.

“This is a significant outcome for the company and will strengthen the already compelling economics for the Lake Way project.

“We are focused on finalising the bankable feasibility study (BFS) which will reflect the pilot plant results and confirm the excellent potential of Lake Way.”

Results achieved from the pilot plant indicate that the product is comparable with other premium-grade soluble products on the market and supports Salt Lake Potash’s marketing strategy to supply into the premium SOP market.

The premium achievable for soluble grade SOP can be up to 20% above the standard pricing.

The process flowsheet that has been developed and confirmed as part of the pilot plant test work has been incorporated in the Lake Way bankable feasibility study (BFS) which is scheduled for completion in early October 2019.

SRC is a world-leading potash processing laboratory.
