Energy Fuels Inc. (NYSE American: UUUU) (TSX: EFR) announced it has produced its first kilogram of 99.9% pure terbium oxide at its White Mesa Mill in Utah, using U.S.-sourced monazite ore. This milestone follows recent production of nearly 30 kilograms of 99.9% dysprosium oxide and supports the company’s strategy to establish a secure domestic supply of critical heavy rare earth materials. The company stated that pilot-scale production will continue at roughly one kilogram per week, with plans to expand to commercial-scale output as early as 2027. Target annual production includes up to 12 tonnes of terbium and 35 tonnes of dysprosium, alongside broader rare earth oxide capacity growth tied to future circuit expansions.
Terbium and dysprosium are heavy rare earth elements essential for high-strength permanent magnets used in electric vehicles, wind turbines, and defense systems. Currently, China dominates global production of these materials, creating supply chain vulnerabilities. Energy Fuels’ achievement represents a significant step toward reducing U.S. reliance on foreign sources. The White Mesa Mill is the only fully licensed and operating conventional uranium processing facility in the United States, and its ability to process rare earths adds a new dimension to domestic critical mineral production.
The company’s broader portfolio includes uranium, vanadium, and heavy mineral sands projects. Energy Fuels is also developing the Toliara Project in Madagascar, the Bahia Project in Brazil, and the Donald Project in Australia. The company’s common shares trade on the NYSE American under the symbol “UUUU” and on the TSX under “EFR.” For more information, visit http://www.energyfuels.com.
The announcement underscores the growing importance of domestic rare earth processing capabilities amid geopolitical tensions and rising demand for clean energy technologies. Energy Fuels’ success in producing high-purity terbium and dysprosium oxides positions it as a key player in the U.S. critical minerals supply chain, with potential implications for national security and economic competitiveness.
