Core Viewpoint - Energy Fuels is advancing its production capabilities for heavy rare earth oxides, specifically dysprosium and terbium, at its White Mesa Mill in Utah, with plans for commercial-scale production by Q4-2026 [1][3][4]. Group 1: Production Achievements - Energy Fuels has successfully produced its first kilogram of dysprosium oxide at a purity of 99.9%, exceeding the commercial specification of 99.5% [1][2]. - The mill is expected to produce dysprosium oxide at a rate of two kilograms per week, with pilot-scale production continuing until approximately 15 kilograms are produced [2][3]. - Following the dysprosium production, the company plans to produce high-purity terbium oxide, targeting Q4-2025 for the first samples [2][3]. Group 2: Strategic Importance - The production of high-purity dysprosium oxide is seen as a significant step towards securing a domestic supply of heavy rare earth oxides for various commercial and defense applications [4]. - Energy Fuels claims to be the first U.S. company to produce high-purity dysprosium oxide and disclose actual production volumes and purities [1][2]. Group 3: Future Plans - The company intends to construct and commission commercial-scale separation capacity for dysprosium, terbium, and potentially other heavy rare earth elements at the White Mesa Mill, with production expected to start as soon as Q4-2026 [3][4]. - Data and knowledge from the pilot plants will inform the design and construction of the commercial separation infrastructure planned for Utah [4][5]. Group 4: Competitive Position - Energy Fuels is positioned as a leading U.S. producer of critical minerals, leveraging existing licenses, facilities, and proven commercial capacity at the White Mesa Mill [5][6]. - The company has previously completed and commissioned a commercial scale "light" rare earth oxide circuit, producing neodymium-praseodymium oxide for use in various technologies [4][5].
