American Rare Earths Announces SynBREE Consortium Produces Heavy & Light Rare Earths Oxide Concentrates using Halleck Creek Ore
Highlights
- Mixed heavy and light rare earth oxide concentrates produced from Halleck Creek’s allanite-based ore as part of the US Department of Defense’s (“DoD”) on-going Defense Advanced Research Projects Agency (“DARPA”) Environmental Microbes as a BioEngineering Resource (“EMBER”) project.
- Results include:
- 97.1% pure Heavy Rare Earth Oxide (“HREO”)
- 96.4% pure Light Rare Earth Oxide (“LREO”)
- First production of Light Rare Earth Oxides (“LREO”) and Heavy Rare Earth Oxides (“HREO”) using Halleck Creek Ore
August 15, 2025 (Source) — American Rare Earths Limited (ASX: ARR | OTCQX: ARRNF | ADR: AMRRY) (“ARR” or “the Company”) announced today that the University of Kentucky (“UK”) produced a heavy rare earths oxide concentrate and light rare earths oxide concentrate from Halleck Creek’s allanite-based ore. These concentrates are precursors to separated rare earth element (“REE”) oxides and this is the first time that they have been produced from Halleck Creek ore.
