Lake aims to bring the project to production by using the efficient, low cost-competitive direct extraction technology from Lake’s technology partner, Lilac Solutions Inc, in California. Lilac has successfully produced high purity lithium chloride eluate from Kachi Project brine samples using its proprietary ion-exchange direct lithium extraction method at pilot plant module scale in California (refer ASX announcement 3 July 2020). Samples of this lithium chloride were further processed into high purity 99.97% lithium carbonate by an independent laboratory, Hazen Research Inc, in Colorado (refer ASX release 6 August 2020; 20 October 2020). Hazen continues to produce lithium carbonate samples for Lake.
Pricing in the lithium carbonate market is largely determined by purity, and the level and type of impurities. The high purity results indicate premium pricing potential, higher than previously envisaged. The Pre-Feasibility Study (PFS) (refer ASX announcement 30 April 2020) was based on achieving 99.9% lithium carbonate and a fixed selling price of US$11,000/t.
