Energy Fuels' dysprosium oxide qualifies for permanent magnet use

Energy Fuels Inc. (NYSE: UUUU) announced that its dysprosium oxide produced at the White Mesa Mill in Utah has passed initial purity and quality control requirements of a major South Korean automotive manufacturer for permanent magnet production.

The company achieved 99.9% purity with its dysprosium oxide, exceeding the automotive specification of 99.5% purity. Energy Fuels has produced approximately 29 kilograms of the material at pilot scale since August 2025.

Dysprosium oxide serves as an additive in neodymium-iron-boron permanent magnets used in electric vehicles, advanced robotics, defense systems including drones and missiles, and naval reactor control rods.

"Production of dysprosium oxide that meets stringent magnet specifications is yet another key milestone in the Company's critical materials strategy," said CEO Mark S. Chalmers.

The qualification follows Energy Fuels' September announcement that its neodymium-praseodymium oxide was also approved for permanent magnet applications. The company states it is the first U.S. company to have both light and heavy rare earth elements qualified for permanent magnet use.

Energy Fuels plans to begin piloting terbium oxide production next week, with kilogram-scale samples expected in early 2026. The company also intends to pilot gadolinium and samarium oxide production.

The company is proceeding with plans to construct commercial-scale infrastructure for dysprosium, terbium, and potentially samarium oxide production at the White Mesa Mill. The planned refining circuits would have annual capacity to produce up to 48 metric tons of dysprosium oxide and 14 metric tons of terbium oxide, subject to available feed materials.

Commercial-scale heavy rare earth production is targeted for the fourth quarter of 2026.
