U.S. GoldMining Provides Update on Exploration Targets at the

Whistler Gold-Copper Project, Alaska

Anchorage, Alaska – May 15, 2025 – U.S. GoldMining Inc. (NASDAQ: USGO) (“U.S. GoldMining” or the “Company”) is pleased to provide an update on the results of exploration target delineation and analysis performed for the Whistler Gold-Copper Project (the “Whistler Project” or the “Project”) in Alaska, U.S.A.

Highlights:

Tim Smith, Chief Executive Officer of U.S. GoldMining, commented: “The three Au-Cu-Ag porphyry deposits which comprise the existing Whistler Project mineral resource estimate - Whistler, Raintree and Island Mountain - occupy only ~1% of the Company’s land holdings, highlighting the broader potential for the Project. Across the Project’s large land package, we have identified numerous additional porphyry or intrusion related drill targets. Importantly, we recognize that the initial deposits delineated from approximately 75,000 meters of drilling completed to date, each occur within a broader mineral system that encompasses similar geological characteristics with the known deposits, thereby highlighting the potential for further discoveries using proven exploration vectors and methodologies.

In addition to the recently announced initial economic assessment launched on the known gold-copper deposits, plus numerous exploration targets defined for further growth, Whistler is located proximally to major infrastructure and stands to benefit from partnering on State-led initiatives that will connect the Project to that infrastructure via the planned West Susitna Access Road. Furthermore, Whistler is situated within one of the more favorable mining jurisdictions in the United States, which is experiencing strong political tailwinds at both State and Federal levels. Coupled with recent all-time high gold prices and predicted strong future demand for copper, we are strongly encouraged by the potential to unlock significant additional value for stakeholders in 2025 and beyond.”

The Company’s geological analysis conducted since completing the 2024 drilling campaign, indicates significant potential to build upon the Company’s first two highly successful field seasons completed at Whistler during the summer of 2023 and 2024, and incorporates knowledge compiled from drilling, relogging of historical drill core, surface mapping and sampling, and geophysical processing and interpretation.

Potential exploration programs are expected to run in parallel to the Company’s previously announced initial economic assessment for the Project, thereby maximizing Whistler’s full potential in investigating not only the mine development potential of the existing resources, but also to build a pipeline of resources which could feed into a larger potential future mining opportunity at the Whistler Project. Exploration programs, which are currently in the design phase, would aim to build upon the successes of the 2023-2024 exploration programs, that included:
