Salt Lake Potash Ltd. said March 18 that total resources at its Lake Way potash project in Western Australia increased to 72.8 million tonnes of sulfate of potash.

In terms of total porosity, the measured resources now stand at 6.9 million tonnes from the Lake Way Playa and 32,000 tonnes from the Williamson Pit. Indicated resources total 3.7 million tonnes from the Paleochannel. Inferred resources from the Lake Way Playa and Paleovalley Sediment are 62.2 million tonnes.

The maiden resource estimate released in July 2018 was limited to the area within the Blackham Resources Ltd. boundary, following which Salt Lake Potash conducted an extensive exploration program covering the remaining areas of Lake Way.

Salt Lake Potash said March 18 that the resource upgrade will enable it to finalize technical studies for a larger production scenario, expected toward the end of the second quarter.

Meanwhile, the company will continue exploration activities at Lake Way as it looks to increase resource definition in the southern section of the lake and eventually convert resources into reserves.

The company recently began building the first phase of the Lake Way evaporation ponds, which will enable dewatering of the Williamson Pit to accelerate efforts for initial sulfate of potash production at Lake Way.
