Laboratory Test Work

Extraction studies are underway to determine the solubility of the lithium and other mineral constituents within the claystone. Representative samples of oxidized and reduced material from DCH-05 were delivered to SGS in Lakefield, Ontario. These initial bench-scale scoping tests revealed moderate extractions of lithium in sulfuric acid solution, increasing to 74% in both sample types with increasing temperatures. The extractions were achieved with relatively low additions of sulfuric acid for lithium-bearing claystone deposits, measured at a rate of 140 kg to 170 kg of acid per tonne of material. The results are encouraging and clearly indicate that the extractions and acid consumptions of the Cypress' Clayton Valley claystone are significantly better than seen in refractory claystone deposits. Further test work is underway to improve the results by refining the leach conditions, checking for any mineralogical variability across the properties, and determining methods of recovery of the lithium from the leach solutions.
