Completion Of Exploration Program At Whistler Gold-Copper Project

ANCHORAGE, AK – U.S. GoldMining Inc. reported that the exploration program recently completed at Whistler Gold-Copper Project focused on targeting continued growth through developing new drill targets at the Whistler Orbit and Muddy Creek prospect areas. The Company’s 2025 exploration program, which was extended to achieve maximum coverage of ‘scout’ drilling over the Whistler – Raintree mineral system has now concluded, with all programs completed safely and on schedule.  A total of 169 scout auger drill holes were completed on a systematic grid pattern over the ‘Whistler Orbit’, an area of approximately 7.5 km by 4.5 km comprising a cluster of porphyry targets surrounding the existing Whistler and Raintree gold-copper porphyry deposits.
Multiple occurrences of new porphyry intrusive rock have been mapped from top-of-bedrock scout drilling within the Whistler Orbit. Scout drilling determined that much of the till overburden in the Whistler Orbit is shallower than previously interpreted, which is a positive indication that targets identified in auger drilling may be close to the surface. Assays of basal till and top-of-bedrock samples are pending. 
Mapping and systematic surface geochemical sampling of the Muddy Creek intrusion related gold system has been completed successfully. Mapping identified new zones of increased quartz vein density in altered volcano-sedimentary host rocks peripheral to granodioritic intrusions, a key diagnostic feature of intrusion related gold systems (e.g. Kinross Gold Corporation’s ‘Fort Knox’ gold mine and Snowline Gold Corp’s ‘Valley’ gold deposit). Six mapping and sampling transects were completed across the gossanous outcrops in the Muddy Creek area, covering a total area of 5 km by 2.5 km. A total of 106 rock grab samples and 7 silt samples were collected. Assay results are pending. Mapping also identified veins containing abundant to massive sulphides, including antimony – bearing minerals.
Tim Smith, Chief Executive Officer, said, “We are pleased to have successfully completed our 2025 exploration program at the Whistler Project in line with our objective to develop a pipeline of targets for potential future discoveries that will underpin growth opportunities for the Project. We also welcome the recent U.S. Federal decision to approve the Ambler Road in north central Alaska, which further supports our belief that the prevailing political tailwinds at all levels of government will help to expedite the successful permitting and ultimate development of the proposed West Susitna Access Road, which is expected to connect the Company’s 100% owned Whistler Gold-Copper Project to transportation infrastructure near Anchorage, Alaska. We look forward to providing further updates on results from our 2025 exploration program as they become available.”
