Energy Fuels Inc. has announced that its 99.9% purity dysprosium oxide produced at the White Mesa Mill in Utah has passed initial quality assurance and quality control benchmarks of a major South Korean automotive manufacturer for use in rare earth permanent magnets. Dysprosium oxide is crucial for enhancing the performance of neodymium-iron-boron magnets, which are used in electric vehicles and defense systems.

The company produced its first kilogram of dysprosium oxide in August 2025 and has since produced approximately 29 kg at pilot scale. Energy Fuels plans to begin pilot production of terbium oxide next week, with samples expected for qualification in early 2026. The company aims for commercial-scale production of dysprosium and terbium oxides by late 2026, with a capacity of up to 48 metric tons of dysprosium and 14 metric tons of terbium annually.
