American Rare Earths Ltd (ASX:ARR, OTCQX:ARRNF) has been selected to supply ore from its Halleck Creek project in Wyoming to a US Department of Energy (DOE) research initiative aimed at strengthening domestic critical minerals supply chains.
The company provided around five tonnes of allanite ore from the Cowboy State Mine test pit at Halleck Creek in December 2025 for the Minerals to Materials Supply Chain Research Facility (METALLIC) consortium, which is led by the National Energy Technology Laboratory.
The METALLIC program brings together research capabilities from nine US national laboratories to validate and improve mineral processing technologies developed by domestic companies, to accelerate commercialisation and reduce risk in critical minerals supply chains.
Halleck Creek ore to support processing trials
Ore from the Cowboy State Mine at the Halleck Creek Rare Earths Project will serve as feedstock for testing across the consortium’s four METALLIC research centres. Researchers will use mineral processing methods developed by American Rare Earths and assess new processing approaches that could improve recovery and refining of magnetic rare earth elements.
The collaboration also provides independent verification of its existing process flowsheets while potentially identifying more efficient and cost-effective processing techniques.
Chief executive Mark Wall said participation in the DOE-backed program aligns with the company’s strategy of advancing what it describes as the largest rare earth deposit in the United States.
American Rare Earths has previously worked with research teams from Lawrence Livermore National Laboratory, Idaho National Laboratory and Oak Ridge National Laboratory, and said the METALLIC consortium enables broader collaboration between these groups.
