ANCHORAGE, Alaska, Sept. 29, 2025 /PRNewswire/ - U.S. GoldMining Inc. (NASDAQ: USGO) ("U.S. GoldMining" or the "Company") was honored to host United States Congressman, Nick Begich on a site visit to its 100% owned Whistler Gold-Copper Project (the "Whistler Project" or "Project") on September 21, 2025. Rep. Begich represents the State of Alaska in the House of Representatives and is a member of the House Committee on Natural Resources. The visit reflects ongoing national-level interest in responsible resource development opportunities in Alaska's West Susitna Mineral District, including the Whistler Project.

Tim Smith, Chief Executive Officer of U.S. GoldMining, commented: "We were delighted to welcome Congressman Begich and to share our vision for the responsible development of the Whistler Project - the closest major undeveloped gold-copper opportunity to Anchorage, Alaska. Rep. Begich's visit to Whistler underscores the growing recognition of the West Susitna Mineral District as a region with significant potential to contribute to Alaska's economy and America's resource security. We greatly appreciate Rep. Begich's time and interest in the Project, and as we continue to advance our previously announced initial economic assessment study (the "PEA") and execute on our 2025 exploration program, we remain committed to working collaboratively with all levels of government, regulatory agencies and other stakeholders towards the long-term development of the Whistler Project."

Rep. Begich's visit follows Senator Lisa Murkowski's tour of the Whistler Project in August 2025, further underscoring the importance Alaska's congressional delegation is placing on the State's resource opportunities. During his tour, Rep. Begich met with members of the Company's technical and operational teams, who shared updates on its ongoing work at Whistler, including both district-scale exploration activities and advancement of the Project's PEA (previously announced on June 9, 2025).

Rep. Begich's visit to Whistler came one week after the House Committee on Natural Resources, Subcommittee on Energy and Mineral Resources held a hearing on Alaska's vast resource potential. The Subcommittee convened a broad panel of Alaskan experts to discuss how responsible development of oil, gas, mineral, and timber resources can enhance national security and drive economic growth in the State. The hearing was prompted by President Trump's recent Executive Order, Unleashing Alaska's Extraordinary Resource Potential, which created a timely opportunity for policymakers to hear directly from Alaskans.

2025 Project Update:

• The Company's 2025 exploration program has been extended into early October to maximize scout drilling coverage over the Whistler – Raintree mineral system. The scout drilling methodology is working well, with several new occurrences of porphyry intrusive lithologies identified from top-of-bedrock drill sampling. Assays are pending.
• Mapping and surface geochemical sampling of the Muddy Creek intrusion-related system has been successfully completed, with assays pending.
• The Company continues to advance its PEA for the Project (previously announced on June 9, 2025), with the objective of defining a potential economic base-case mining opportunity.
• Recently released metallurgical test work (previously announced on September 22, 2025), a key component of the PEA, demonstrated gold recoveries of 85.3%, representing a 22% improvement over prior results.
