Energy Fuels Inc. (NYSE American: UUUU) (TSX: EFR) announced it has successfully produced its first kilogram of 99.9% pure terbium oxide at its White Mesa Mill in Utah using U.S.-sourced monazite ore, meeting specifications for global rare earth permanent magnet manufacturers. 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.
Energy Fuels said pilot-scale production will continue at roughly one kilogram per week, with plans to expand to commercial-scale output as early as 2027, targeting annual production of up to 12 tonnes of terbium and 35 tonnes of dysprosium, alongside broader rare earth oxide capacity growth tied to future circuit expansions. The company’s White Mesa Mill is the only fully licensed and operating conventional uranium processing facility in the United States, and it is now also producing advanced rare earth element products.
This development is significant because terbium and dysprosium are critical components in permanent magnets used in electric vehicles, wind turbines, and other clean energy technologies. Currently, China dominates the global supply of these heavy rare earth elements, creating supply chain vulnerabilities. Energy Fuels’ production from U.S.-sourced ore represents a step toward reducing this dependence.
Energy Fuels is also developing additional heavy mineral sands projects, including the Toliara Project in Madagascar, the Bahia Project in Brazil, and the Donald Project in Australia, where it has the right to earn up to a 49% interest in a joint venture with Astron Corporation Limited.

The company noted that the White Mesa Mill’s rare earth production is part of a broader strategy to become a leading U.S.-based critical minerals company, focusing on uranium, rare earth elements, heavy mineral sands, vanadium, and medical isotopes. Energy Fuels has been the leading U.S. producer of natural uranium concentrate for several years, sold to nuclear utilities for carbon-free nuclear energy production.
This announcement underscores the growing momentum behind domestic critical mineral supply chains, supported by policy initiatives such as the Inflation Reduction Act and the Defense Production Act. As Energy Fuels scales its production, it could help meet the increasing demand for rare earth materials essential for the energy transition.
