Cypress Development Corp owns lithium claystone deposits in Clayton Valley, Nevada that have the potential to be a significant lithium resource. Drilling in 2017 encountered mineralization averaging 921 ppm lithium over 77 meters thick in 14 drill holes. Metallurgical testing shows the claystone is acid leachable with up to 80% lithium extraction. Cypress plans additional drilling, metallurgical testing, and a preliminary economic assessment in 2018 to further define the resource potential.
