Energy Fuels Inc. 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 successful production represents a significant development for U.S. critical mineral independence, as terbium and dysprosium are essential components in high-performance permanent magnets used in electric vehicles, wind turbines, and other clean energy technologies. These rare earth elements have traditionally been dominated by foreign supply chains, creating strategic vulnerabilities for American manufacturing and energy security.
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. The company is 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. This expansion timeline aligns with growing demand for domestically sourced critical minerals as the clean energy transition accelerates.
The White Mesa Mill in Utah serves as a strategic asset in this development, being the only fully licensed and operating conventional uranium processing facility in the United States. The facility’s ability to produce advanced rare earth element products positions Energy Fuels to play a central role in building domestic supply chains for materials essential to national security and economic competitiveness.

The broader implications of this achievement extend beyond Energy Fuels’ corporate strategy to address systemic vulnerabilities in U.S. manufacturing supply chains. As industries increasingly rely on rare earth elements for technological advancement, domestic production capabilities become crucial for economic resilience and strategic autonomy. The company’s progress demonstrates the feasibility of establishing complete rare earth supply chains within the United States, from ore extraction to high-purity oxide production.
