Energy Production at White Mesa Mill in Utah Yields First Kilogram of 99.9% Pure Dysprosium Oxide; Preparations Underway for Terbium Production in Q4 2025
In a significant breakthrough, Energy Fuels Inc., a leading U.S.-based critical minerals company, has completed the production of its first kilogram of dysprosium oxide at pilot scale at the White Mesa Mill in Utah. This makes Energy Fuels the first U.S. company to both produce high-purity Dy oxide and publicly disclose actual production volumes and purities.
The White Mesa Mill, the only fully licensed and operating conventional uranium processing facility in the United States, is owned by Energy Fuels. At the mill, advanced REE products, including dysprosium oxide, are produced, alongside vanadium oxide (when market conditions warrant), and the potential recovery of certain medical isotopes for emerging Targeted Alpha Therapy cancer treatments is being evaluated.
Energy Fuels, which has its headquarters in Lakewood, Colorado, near Denver, is a leading U.S. producer of uranium, rare earths, and critical minerals. The company has been the leading U.S. producer of natural uranium concentrate for several years, which is sold to nuclear utilities for further processing into carbon-free nuclear energy.
The produced dysprosium oxide boasts a purity of 99.9%, a testament to Energy Fuels' commitment to quality and excellence. The company plans to produce dysprosium oxide at a rate of two kilograms per week.
Looking ahead, Energy Fuels intends to construct and commission commercial-scale Dy, Tb, and potentially other "heavy" REE separation capacity at its White Mesa Mill. This could see production as soon as Q4 2026. In addition, Energy Fuels has announced the completion and commissioning of its commercial scale "light" rare earth oxide circuit at the White Mesa Mill.
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. The company has the right to earn up to a 49% interest in a joint venture with Astron Corporation Limited for the Donald Project.
Mark S. Chalmers, previously the President and COO of Energy Fuels, assumed the role of CEO. Under his leadership, Energy Fuels continues to push boundaries in the production of critical minerals, contributing significantly to the U.S.'s energy independence and the global supply chain of these essential resources.
Energy Fuels' common shares primarily trade on the NYSE American under the symbol "UUUU," and are also listed on the Toronto Stock Exchange under the symbol "EFR."
