Industry Context

This announcement positions U.S. GoldMining as actively advancing a significant gold-copper porphyry project in Alaska, a region known for its mineral potential and existing mining infrastructure. The focus on a Preliminary Economic Assessment (PEA) is a standard step in the mining industry to evaluate the economic viability of a project before committing to further development stages, aligning with broader industry trends of de-risking projects through detailed studies.

Comparison to Industry Standards

• The selection of Ausenco, a global engineering firm with a 30-year track record in minerals and metals, aligns with industry best practices for engaging experienced consultants for critical economic assessments.
• The mineral resource estimates (6.48 Moz AuEq Indicated and 4.16 Moz AuEq Inferred) for the Whistler Project are substantial, placing it among notable gold-copper porphyry deposits globally, though direct comparison to specific projects like Grasberg (Indonesia), Oyu Tolgoi (Mongolia), or Cadia Valley (Australia) would require more detailed economic and geological parameters not provided in this document.
• The use of U.S. Regulation S-K 1300 and Canadian National Instrument 43-101 standards for the PEA ensures compliance with leading North American disclosure requirements for mineral projects, providing transparency and comparability for investors.

Stakeholder Impact

• Shareholders: Potential for significant value creation if the PEA demonstrates a robust mining opportunity, as stated by management.
• Employees: Future potential for job creation if the project advances to development and production phases.
• Local Communities (Anchorage, Matanuska-Susitna Borough): Potential for economic benefits through project development, employment, and infrastructure utilization.

Next Steps

• Ausenco Engineering Canada ULC will lead the initial assessment study (PEA) for the Whistler Gold-Copper Project.
• An updated mineral resource estimate, including 2024 drilling data, will be completed by Moose Mountain Technical Services for incorporation into the PEA.
• Metallurgical test work by Base Metallurgical Laboratories Ltd. will continue and be utilized in the PEA.
• U.S. GoldMining will provide periodic updates as the PEA study progresses.
• The Company is targeting completion of the PEA before year-end.
