American Rare Earths (ASX: ARR, OTCQX: ARRNF, ADR: AMRRY) signed a Memorandum of Understanding with U.S. metallization specialist Novex to convert separated rare earth oxides from the Halleck Creek project in Wyoming into metals for permanent magnets. The MoU, executed via subsidiary Wyoming Rare (USA), frames collaboration on process optimization for NdPr, Tb, Dy, Sm and Y, metallization of demonstration-plant NdPr oxide, and joint design of a rare earth metal production facility to be built by American Rare Earths.
The agreement follows a technology review that identified high‑temperature molten salt electrolysis as the primary oxide‑to‑metal route. Halleck Creek hosts a JORC mineral resource of about 2.63 billion tonnes of rare earth oxides and benefits from a non‑binding U.S. EXIM Bank funding letter of interest up to US$456 million. The parties aim to finalize a definitive long‑term collaboration and supply agreement within 12 months, supporting a fully domestic U.S. mine‑to‑magnet supply chain.
