Key Takeaways Energy Fuels stock jumped 8% in a week, riding on the breakthrough in dysprosium. UUUU produced 99.9% pure dysprosium oxide at White Mesa and passed QC by a major magnet maker. Energy Fuels plans to scale terbium and samarium output by 2026, strengthening rare earth supply chains. Energy Fuels Inc. (UUUU)  have jumped 8% over the past week, since it announced that the 99.9% purity dysprosium oxide produced at its White Mesa Mill has passed the stringent QC (Quality Check) requirements of a maj ...

Core Insights - Energy Fuels Inc. has successfully produced high purity dysprosium oxide (99.9%) at its White Mesa Mill, which has passed initial quality assurance and quality control benchmarks set by a major South Korean automotive manufacturer for rare earth permanent magnet production [2][4][5] - The company plans to begin pilot production of terbium oxide in early 2026, with plans for samarium oxide production to follow, indicating a strategic expansion in the production of critical rare earth elements [6][7] Company Developments - The production of dysprosium oxide is a significant milestone for Energy Fuels, marking the first U.S. company to qualify both "light" and "heavy" rare earth elements for use in permanent magnet applications, which is crucial for the U.S. rare earth supply chain [4][5] - Energy Fuels has produced approximately 29 kilograms of high-purity dysprosium oxide since August 2025, exceeding automotive specifications [5] - The company is also planning to construct infrastructure for commercial-scale production of dysprosium and terbium oxides, with an expected capacity of up to 48 metric tons of dysprosium oxide and 14 metric tons of terbium oxide annually [8] Industry Context - Dysprosium oxide is essential for enhancing the durability and magnetic performance of neodymium-iron-boron permanent magnets, which are used in electric vehicles, advanced robotics, and defense systems [3] - The supply of dysprosium and other heavy rare earth oxides is limited outside of China, especially following China's export controls on several rare earth elements [4]

Core Viewpoint - Energy Fuels is advancing its production of heavy rare earth element oxides, with potential commercial production starting as early as Q4 2026, addressing the U.S. demand for these critical minerals [1][4][6]. Production Update - Energy Fuels has begun pilot-scale production of Dysprosium (Dy) oxide with a minimum purity of 99.5%, expecting to produce its first kilogram within 30 days and approximately 15 kg by the end of September 2025 [3][4]. - The company plans to start producing Terbium (Tb) oxide by the end of November 2025 and anticipates beginning production of Samarium (Sm) oxide in January 2026 [3][4]. Unique Position in the Market - Energy Fuels is the only U.S. company producing separated heavy rare earth oxides from mined ores at a commercial facility, differentiating itself from competitors who focus on recycling [5][9]. - The company has successfully separated Neodymium and Praseodymium (NdPr) on a commercial scale since April 2024, positioning itself to meet the needs of U.S. manufacturers for rare earth metals and alloys [6][9]. Donald Project Insights - The Donald Project in Australia is a significant source of heavy rare earth elements, containing high concentrations of xenotime, which is rich in Dy, Tb, and Sm [7]. - The project is expected to produce approximately 129 tonnes of Sm, 16 tonnes of Tb, and 92 tonnes of Dy annually, significantly exceeding current U.S. requirements [7]. - If production decisions are made in 2025, commercial production from the Donald Project could commence by the end of 2027 [4][7]. Future Projects - Energy Fuels is also developing the Toliara Project in Madagascar, targeted to come online as early as 2028, and the Bahia Project in Brazil, expected in 2029, both containing significant quantities of light and heavy rare earth oxides [8][9].
