US GoldMining Inc. has announced that it is well underway with exploration at its 100% owned Whistler Gold-Copper Project for the 2025 field season in Alaska. The programme is focused on targeting continued growth through developing new drill targets at the Whistler Orbit and Muddy Creek prospect areas. The Company is also delighted to have recently hosted United States Senator Lisa Murkowski on a visit to the Project on August 21, 2025.
The Company’s 2025 exploration focus is more expansive in area and exploration methodology than previous seasons, which focused on drilling to delineate and grow the Whistler deposit mineral resource. Current exploration adds the supplementary objective of developing a pipeline of exploration targets at the district-scale, with the aim of expanding the projects resource base through follow-up exploration campaigns.
“We’re excited to have launched our 2025 exploration campaign that will explore multiple targets across our mineral district-scale Whistler Project land package,” Tim Smith, Chief Executive Officer of US GoldMining, commented. “As we work in parallel to advance the PEA over the existing mineral resources, the Programme will build upon the geological advances made in 2023 and 2024 with the objective of developing a pipeline of targets for potential future discoveries that will underpin growth opportunities for the Project. I want to commend our field teams for achieving startup of the 2025 exploration programme safely and on schedule. We look forward to providing further Project updates on progress and results from our 2025 exploration programme as results become available.
“Furthermore, I’d like to express on behalf of the Company our gratitude to Senator Murkowski for taking time out of her busy schedule to visit the Project. It was exciting to share our vision for the advancement and continued growth of Whistler, and we’re delighted to have a potential advocate for Whistler and the broader West Susitna Mineral District in Washington D.C. As we advance our proposed PEA and execute on our 2025 exploration programme, we remain committed to working collaboratively with all levels of government, regulatory agencies and other stakeholders in support of both the West Susitna Access Project and the long-term development of the Whistler Project.”
The Company recently mobilised field teams to the Project, commencing with camp opening and drill pad clearing, followed by mobilisation of scout drilling equipment. The scout drilling programme over the Whistler Orbit target area first commenced at the ‘Big White’ target area located north of Whistler Deposit and will transition to several additional targets in the coming weeks. The programme comprises shallow ‘base of till / top of bedrock’ auger drilling, utilising a small mobile ‘shock auger’ drill which specialises in penetrating unconsolidated till deposits to rapidly and cost effectively test multiple near surface target areas. The objective of this drilling is to vector towards fertile porphyry intrusions and define future deeper follow-up drill targets, likely for drill testing in 2026. The Company has defined over 25 individual potential exploration targets within the Whistler – Raintree mineral system (see news release dated May 27, 2025) comprising geophysical signatures similar to the known Whistler deposit.
At the Muddy Creek target area, historic exploration included reconnaissance rock chip sampling which returned 73 samples that assayed >1 gram per tonne gold (“g/t Au”), including 20 samples which assayed >10 g/t Au, and peak values of 111.50 g/t Au, 69.13 g/t Au and 56.6 g/t Au (see news release dated June 16, 2025). Follow-up sampling and mapping in 2025 will aim to define zones of higher density quartz veining and develop geochemical pathfinders to stronger bedrock mineralisation, with the overall objective to define targets for a future follow-up drilling programme.
