USCM Commences Exploration at Long Canyon Uranium and Vanadium Property in Developing Market for US Uranium Demand

• Samples show uranium up to 3,985 ppm and vanadium up to 2,499 ppm, indicating strong mineralization potential.

• Shares geological similarities with world-class shale-hosted deposits.

• Program underway for detailed mapping, sampling, gamma-ray scanning, and stratigraphic profiling.

• Idaho's mining-friendly regulations and recent U.S. federal policy shifts toward domestic uranium production position Long Canyon for accelerated advancement.

Vancouver, British Columbia--(Newsfile Corp. - June 10, 2025) - US Critical Metals Corp. (CSE: USCM) (OTCQB: USCMF) (FSE: 0IU) ("USCM" or the "Company") is pleased to announce the commencement of a program for the Long Canyon Uranium and Vanadium Project in Idaho ("Long Canyon" or the "Project"). Long Canyon is part of an underexplored geologic environment that has the potential to develop into a large-scale exploration opportunity. Black shale-hosted uranium and vanadium deposits have economic potential in multiple jurisdictions and are known to contain significant resources. This positions Long Canyon to potentially become a new geologic source of uranium and vanadium within the United States (the "U.S."). Long Canyon is in partnership with IDEX Metals Corp. (for more information see Company's press release - access here).

Executive Order

Given the political shift to deglobalize and secure domestic sources of supply, the program is strategically timed to capitalize on the sweeping US federal directive to expand nuclear energy and reform uranium permitting processes in the US, as set forth in the Executive Order released on May 23, 2025 (for more information see Executive Order - access here). Long Canyon is ideally positioned given it has the hallmarks of a polymetallic shale-hosted system to benefit from these initiatives. With the U.S. federal government actively dismantling regulatory roadblocks to domestic uranium production and reactor deployment, Long Canyon stands to benefit from:

• Increasing demand for domestic uranium.

• Accelerated permitting windows.

• Federal support for critical mineral supply chains.

• Increased interest in North American uranium assets.

Field Program

Led by Palliser Exploration Ltd. ("Palliser"), an experienced geologic and exploration consultancy, the program is designed to advance the understanding of uranium, vanadium, molybdenum, lead, and zinc mineralization within the carbonaceous black shales of the Blue Dome District. This campaign will integrate systematic rock sampling, radiometric analyses, and structural mapping to refine drill targeting and exploration models.
