Independent Studies Further Validate the American Rare Earths’ (ARR) Halleck Creek Project
DENVER, May 06, 2024 (GLOBE NEWSWIRE) -- American Rare Earths (ASX: ARR | OTCQX: ARRNF and AMRRY) (“ARR” or the “Company”) is pleased to announce results from a 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.
- Fast leaching kinetics are attributable to Halleck Creek metamict allanite structure, with 65% of REEs extracted in the first 10 minutes of leaching.
- Halleck Creek ore is less refractory than monazite or bastnaesite, which cannot be leached using low-temperature acid tank leaching.

High-grade rare-earth enriched Halleck Creek ore highlights its economic potential. - Donald Swartz, Chief Executive Officer of American Rare Earths commented:
“We’re extremely pleased with the leaching results which further validate the recent scoping study assumptions and our optimism around the project.
