Cypress Development Corp owns lithium claystone deposits in Clayton Valley, Nevada near Albemarle's Silver Peak lithium mine. Drilling in 2017 encountered mineralization averaging 921 ppm lithium over 77 meters thick in 14 drill holes. Metallurgical tests show 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 evaluate the project's potential.
