What U.S. Critical Materials does
U.S. Critical Materials Corp. is a privately held (Nevada-incorporated) exploration and process-technology company focused on rare earth elements, gallium, and other critical minerals. Its flagship asset is the Sheep Creek deposit in Ravalli County, Montana, independently validated by Activation Labs and Idaho National Laboratory as the highest-grade rare earth deposit in the United States, with TREO grades approaching 9% (~89,932 ppm), combined neodymium-praseodymium concentrations of 2.4%, and gallium averaging 300 ppm (6x typical Chinese production). The company also holds the Lemhi Pass property in Idaho and operates 223 lode claims covering approximately 4,700 acres, with 60+ carbonatite formations identified across the 7,277.5-acre explored area. Critically, average thorium content of approximately 200 ppm sits well below the 500 ppm NRC permitting threshold, materially simplifying the regulatory pathway.
The company's technology stack centers on proprietary processing rather than mining itself: an Electrochemical Extraction and Purification method using an Electrochemical Membrane Reactor (EMR) developed under a Phase II CRADA with Idaho National Laboratory, which consumes only electricity, water, and nitrogen to separate gallium and rare earths from ore. Processing IP is augmented by Colorado School of Mines technologies exclusively licensed through Bayan Mining and Minerals, and by an AI-Powered Mineral Targeting platform from VerAI Discoveries that has been claimed to improve exploration success rates by 100x versus industry benchmarks. The company also runs a two-year 'Mud to Metal' sponsored research program with Columbia University to extract critical metals from red mud (bauxite residue).
U.S. Critical Materials is pre-revenue and does not conduct mining directly; it operates through joint venture entity US Rare Elements Corp. with US Critical Metals Corp. (TSXV: USCM) as a minority earn-in partner and seeks established mining operators or end users to file permits and conduct extraction. Revenue is intended to flow from forward offtake contracts (the first, with REalloys, reserves up to 10% of production for heavy rare earths and NdPr ahead of the January 2027 DFARS deadline), end-user pre-investments by automakers, turbine makers, and defense contractors, and licensing of processing technology to other U.S. and allied-country deposits. First production is targeted for 2H 2026.

Products and services
- Sheep Creek Rare Earth and Gallium Deposit The company's flagship high-grade rare earth and gallium deposit located in Ravalli County, southwestern Montana, covering approximately 4,700 acres across 223 lode claims. Features TREO grades approaching 9% (89,932 ppm), combined neodymium and praseodymium concentrations of 2.4%, gallium concentrations averaging 300 ppm (six times higher than typical Chinese production), and low thorium content averaging 200 ppm (below the 500 ppm NRC threshold). Contains 13 of the critical risk elements defined by the U.S. Geological Survey, including neodymium, praseodymium, dysprosium, terbium, cerium, europium, gadolinium, lanthanum, niobium, scandium, strontium, gallium, yttrium, and samarium.
- Electrochemical Extraction and Purification Technology Proprietary processing technology developed with Idaho National Laboratory using an Electrochemical Membrane Reactor (EMR) that consumes only electricity, water, and nitrogen to extract gallium and rare earth elements from ore. The technology dramatically reduces chemical and waste generation while lowering costs compared to conventional processing methods, and is planned to be licensed to other deposits in the U.S. and friendly countries.
- Colorado School of Mines Processing Technologies Rare earth processing technologies exclusively licensed through Bayan Mining and Minerals from the Colorado School of Mines, including beneficiating, leaching, and separation processes designed for bastnaesite- and ancylite-hosted rare earth systems. Being evaluated for application at the Sheep Creek deposit with structured metallurgical test programs and laboratory validation.
- Mud to Metal Research Program Two-year research collaboration with Columbia University, led by Professor Greeshma Gadikota, to develop methods for extracting defense-critical metals (gallium, scandium, titanium, and rare earth elements) from red mud—an industrial byproduct of aluminum refining, including Alcoa facility waste streams. The program develops extraction pathways for secondary recovery of critical minerals.
- VerAI AI-Powered Mineral Targeting Platform AI/ML-powered exploration platform deployed under partnership with VerAI Discoveries that analyzes geophysical data to identify high-probability drill targets under covered terrain at Sheep Creek. The technology has identified multiple drill-ready targets on adjacent land with characteristics similar to known mineralization and is reported to increase exploration success rates by 100x compared to industry benchmarks.
