PERTH, AUSTRALIA – American Rare Earths Limited (ASX: ARR | OTCQX: ARRNF | ADR: AMRRY), an ASX listed rare earths explorer, is pleased to share the successful results of innovative metallurgical studies focused on the extraction of Rare Earth Elements (REE) from the Halleck Creek project. These results, achieved through collaborative research with the U.S. Department of Energy and Virginia Tech, signify a major step forward in the economic viability and sustainability of rare earth element mining.
Key Findings:
- Two peer-reviewed studies confirm the potential for high-grade, economically viable extraction of REEs from the Halleck Creek ore using low temperature, direct acid leaching techniques.
- Significant breakthroughs include a recovery rate of 80% of REEs within the first 10 minutes using low temperature acid leaching, setting a new industry standard for efficiency and environmental responsibility.
- The studies demonstrate that Halleck Creek ore is more amenable to extraction than traditional sources like monazite or bastnaesite, which require higher temperature processes.
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. 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”.
Dr. Wencai Zhang, of Virginia Tech, commented on the results: “The low-crystallinity characteristic of the allanite can significantly reduce the extraction costs of REEs from the deposit. I am very excited about our recent findings”.
