Cypress Development Corp. announced that the company has received solubility study assay results from Cypress’ 2,700 acre Dean Lithium Brine/Claystone Project located in the heart of the Clayton Valley lithium exploration area of Esmeralda county, Nevada. Highlights: Cypress completes solubility studies on 48 previously assayed Dean claystone samples; A deionized water leach process returns 36.15% Li recovery on average; A modified dilute acid leach process returns 94.72% Li recovery on average; Permit application made to BLM, Nevada for a series of drill holes into new Frontera Verda Zone; Cypress anticipates drilling to begin at the end of January. Cypress has now completed solubility studies with 48 previously assayed claystone samples from the Dean property. A modified dilute Aqua Regia (dilute acid) process (ME-MS41W) and a deionized water leach process (ME-MS03) has been carried out by ALS/Chemex lab in Reno, Nevada in order to provide Cypress with further data on the potential feasibility of a large-scale leach extraction method of lithium from the abundant mineralized claystone. The additional assay procedures recently carried out on the samples by ALS/Chemex from the Dean property clearly show that the lithium in the uplifted exposed lake bed sediments is easily leached by a dilute acid solution and deionized water process.
