Studies Further Validate The Halleck Creek Project

DENVER, CO - American Rare Earths reported on the metallurgical study on leaching extraction of REE from Halleck Creek ore by low temperature, direct acid leaching. The U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy (EERE) awarded a three-year (2022-2025) research contract to Phinix, LLC with American Rare Earth and Virginia Tech as team members. This metallurgical study was carried out by researchers at the Department of Mining and Minerals Engineering at Virginia Tech. These positive results further confirm the findings of the metallurgical testwork carried out by Wood PLC1 which were previously announced by ARR.

Donald Swartz, Chief Executive Officer, said, “We’re extremely pleased with the leaching results which further validate the recent scoping study assumptions and our optimism around the project. High REE recovery at low temperatures with short duration indicate low(er) operating costs and effective extraction of rare earths. ARR is pleased that we have been able to work with the Department of Energy, Phinix and Virginia Tech on this project and look forward to continuing the relationship in the next phases of the EERE project.”
