Excellent news from Cypress on leach results ……………..

On February 20th, Cypress announced additional results that confirm the high solubility of lithium in claystone from its 100%-owned Clayton Valley Project in Nevada.  As previously reported (January 9, 2018 press release), lithium extractions of 74% were obtained for both oxidized and reduced claystone samples from drill core from hole DCH-05, leached in a solution of 5% sulfuric acid heated to 80°C. Subsequent tests reported today show lithium extractions of 67% for the oxidized claystone and 80% for the reduced claystone sample, leached under identical conditions but using a solution of 10% sulfuric acid heated to 50°C. These results are in line with previous results and continue to demonstrate the solubility of lithium found in the subsurface claystone at Clayton Valley using sulfuric acid. An opportunity to improve extractions by adjusting leach conditions is now also apparent.  See the full release here
