On 13 October 2025, U.S. GoldMining Inc. announced that it had finished its 2025 exploration program at the Whistler Gold‑Copper Project in Alaska. The program, which began in early August, involved mobilizing field teams, clearing drill pads, and conducting scout drilling across the Whistler Orbit and Muddy Creek areas. The company stated that the effort was completed in line with its objective to develop a pipeline of targets for future discoveries.
The exploration program employed shallow ‘base of till/ top‑of‑bedrock’ auger drilling using a mobile shock auger. The drill intersected multiple occurrences of porphyry intrusive rocks in top‑of‑bedrock samples that had not been identified previously. The company defined more than 25 individual potential exploration targets within the Whistler‑Raintree mineral system, expanding the known footprint of the project.
At the Muddy Creek prospect, historic reconnaissance sampling had returned 73 rock grab samples with gold grades above 1 g/t Au, including 20 samples above 10 g/t Au. Peak values reached 111.50 g/t Au, 69.13 g/t Au, and 56.6 g/t Au. In 2025, the company completed six mapping and sampling transects covering a 5 km × 2.5 km area, collecting 106 rock grab samples and 7 silt samples; assay results are pending.
The company welcomed the recent U.S. federal decision to approve the Ambler Road in north‑central Alaska, a development that supports the broader infrastructure plan for the Whistler Project. The completion of the exploration program aligns with U.S. GoldMining’s strategic timeline and positions the project for the next phase of development.
