U.S. GoldMining Inc.

2026 Exploration Program Progress

The Company’s diamond core drilling campaign remains active with two rigs operating at site. Drilling to date has focused on testing high-priority porphyry targets within the broader Whistler Orbit area, where multiple stacked geological, geochemical, and geophysical vectors have delineated high-priority anomalies.

Concurrently, field crews are progressing surface exploration, including detailed mapping, geochemical sampling, and prospecting over regional target areas, including Snow Ridge, Long Lake Hills, Muddy Creek, and Island Mountain, to maintain a deep pipeline of drill-ready targets for future campaigns.

Core logging and sampling facilities are fully operational on site, and initial batches of core samples have been dispatched to the laboratory with initial assay results anticipated in the coming weeks.
