(“USCM”) and Bayan Mining and Minerals Ltd (“Bayan”) announce the execution of a non-binding Memorandum of Understanding (“MOU”) to evaluate rare earth processing technologies on high-grade mineralization from US Critical Materials Sheep Creek Project in Montana. The collaboration supports the shared objective of accelerating a U.S.-based rare earth processing pathway aligned with national-security, and the advancement of high priority AI technologies. US Critical Materials’ Sheep Creek Project, located in Ravalli County, Montana, is the highest-grade validated rare earths deposit in the United States, containing light and heavy rare earth elements, including gallium, scandium, yttrium and other strategic minerals. US Critical Materials continues to advance its integration strategy through its technical partnerships, including ongoing work with Idaho National Laboratory, Columbia University, and Montana Technological Institute. Bayan holds an exclusive global license to a suite of rare earth processing technologies developed by the Colorado School of Mines. The collaboration will evaluate the applicability of these technologies—focused on beneficiation, leaching, and separation—to Sheep Creek’s bastnaesite- and ancylite-hosted rare earths systems. Advancing Domestic Processing Capability The collaboration will undertake a structured metallurgical test program to assess recovery performance, process efficiency, and flowsheet optimization. Workstreams will be coordinated through a joint technical committee, with US Critical Materials maintaining oversight to ensure alignment with U.S. domestic-processing and national-security objectives. The evaluation will include laboratory validation, iterative optimization, and scalability assessment. The results will inform potential downstream integration and future development decisions. Executive Commentary Harvey Kaye, Executive Chair of U.S. Critical Materials Corp., stated: “This collaboration allows US Critical Materials to evaluate innovative processing technologies on some of the highest-grade rare earth mineralization in the United States. Our focus is to accelerate a U.S.-based processing pathway that strengthens national security, reduces foreign dependence, and unlocks the full potential of the Sheep Creek Project.” Nathan Kong, Chief Executive Officer of Bayan Mining and Minerals Ltd, commented: “We look forward to supporting US Critical Materials’ evaluation of our technologies as they assess potential applicability to Sheep Creek’s unique mineral systems. This collaboration provides an opportunity to demonstrate the versatility of our processing platform within a U.S.-focused development framework.” Pathway to Commercialization US Critical Materials and Bayan will assess opportunities to establish a U.S.-based pilot or demonstration facility to support technology validation and scale-up. Any future development will be integrated with US government and commercial industry requirements. All intellectual property, data, samples, and technical outputs generated from Sheep Creek remain the exclusive property of US Critical Materials. Any new intellectual property arising from the Collaboration will be subject to definitive agreements. Potential Strategic Investment US Critical Materials is evaluating a potential investment in Bayan that would provide visibility into complementary processing technologies. Any investment remains subject to definitive agreements and regulatory approvals.
