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.
The company said pilot-scale production will continue at roughly one kilogram per week, with plans to expand to commercial-scale output as early as 2027. Energy Fuels targets 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 White Mesa Mill is the only fully licensed and operating conventional uranium processing facility in the United States, and Energy Fuels is leveraging its infrastructure to produce advanced rare earth element products.
This development is significant as it addresses the growing demand for rare earth elements used in permanent magnets for electric vehicles, wind turbines, and defense technologies, reducing reliance on foreign supply chains. The United States currently imports most of its rare earth materials, and domestic production of heavy rare earths like terbium and dysprosium is critical for national security and clean energy goals.
Energy Fuels is a leading U.S.-based critical minerals company, focused on uranium, rare earth elements, heavy mineral sands, vanadium, and medical isotopes. The company owns and operates several uranium projects in the western United States and has been the leading U.S. producer of natural uranium concentrate for the past several years.

Energy Fuels is also developing three additional heavy mineral sands projects: the Toliara Project in Madagascar; the Bahia Project in Brazil; and the Donald Project in Australia, in which Energy Fuels has the right to earn up to a 49% interest in a joint venture with Astron Corporation Limited. The company is based in Lakewood, Colorado, near Denver.
This announcement underscores the strategic importance of domestic production of critical minerals. By producing high-purity terbium oxide, Energy Fuels is positioning itself as a key player in the rare earth supply chain, which is essential for the transition to a green economy. The company's ability to scale production to commercial levels by 2027 could significantly impact the availability of these materials for U.S. manufacturers.
