Super Critical Carbon Dioxide Extraction Testing For The Gemini Project

VANCOUVER - Nevada Sunrise Metals Corp. announced that metallurgical testing is underway on lithium mineralization from Gemini Lithium Project in Nevada, utilizing super critical carbon dioxide as a leaching agent. A new patent granted by the U.S. Patent and Trademark Office in August 2023 to the Company's consultant, Willem Duyvesteyn, M.Sc. of Extractive Metallurgy Consultants LLC of Reno, Nevada (EMC), is currently being tested on Gemini clay mineralization. EMC's patented process could revolutionize the extraction of lithium from clay deposits by offering a "green" processing method while at the same time providing in-ground sequestration of captured carbon dioxide.

While the initial focus of the scCD testing is on the ex-situ, or off-site, processing of lithium-bearing clays, EMC has also identified the opportunity to use an in-situ approach employing freeze walls to contain the CO2 in a section of a lithium-bearing clay deposit while implementing carbon capture of the CO2 used during the lithium extraction process.
