, July 21, 2025 /CNW/ - U.S. GoldMining Inc. (NASDAQ: USGO) (" U.S. GoldMining" or the " Company") is pleased to provide an update on the Whistler Gold-Copper Project (the " Project") in Alaska, U.S.A. The Company is currently preparing and mobilizing for the 2025 field season which will focus on developing new potential porphyry gold-copper drill targets within the Whistler Orbit and undertaking follow-up mapping and sampling at the Muddy Creek prospect.
2025 Planned Exploration Program Highlights:
The 2025 exploration program expands the scope from previous seasons, which focused on delineating and growing the Whistler deposit. As the Company advances its previously announced initial assessment study (" PEA") for the Project (see news release dated June 9, 2025) with the objective of defining a potential economic base-case mining opportunity, the Company's exploration focus now turns to developing a pipeline of exploration targets at the district-scale, which aims to deliver additional future potential mineral resources over the longer term.
The focus of the planned 2025 exploration program (the " Program") is to develop new drill targets for potential gold-copper mineralization within the Whistler – Raintree mineral system, also referred to as the ' Whistler Orbit ', which comprises a classic 'porphyry cluster' spread over an area of approximately 5 x 5 km, containing multiple mapped and interpreted porphyry intrusions and including the established Whistler and Raintree West mineral resource deposits.
The Program will also include follow-up mapping and sampling of the Muddy Creek mineral system – a large gold-in-soil geochemical footprint over an area of approximately 6 km x 4 km with an intrusion-related gold geochemical signature.
Tim Smith, Chief Executive Officer of U.S. GoldMining, commented:"The near all-time high prices for gold, copper and silver create an ideal environment to advance the Project on multiple fronts. Thus, as the Company progresses its initial assessment study, we are excited to also announce our 2025 exploration plans. The Program will build upon the geological advances made in 2023 and 2024, with the objective to develop a pipeline of targets and potential future mineral resources to underpin the Project over the longer term. The three established mineral deposits which comprise the existing Project mineral resource estimate - Whistler, Raintree and Island Mountain - occupy only ~1% of the Company's land holdings, highlighting the broader exploration potential for the Project. Across our large land package, located 100% on State of Alaska Mining claims, we have identified numerous additional porphyry and intrusion related targets, ranging from early stage gold-in-soil and geophysical anomalies through to more advanced drill targets. The Program, to be funded from existing treasury, will have the objective of delivering new targets for systematic follow-up via future drilling programs. We look forward to providing updates on progress and results as the Program advances."
2025 Program Details
The Company is readying to mobilize field teams to the Project in the coming weeks and expects to commence drilling shortly thereafter at the Whistler – Raintree mineral system (see Figure 1). Exploration will initially comprise shallow base of till / top of bedrock auger drilling, utilizing a small mobile 'shock auger' drill which specializes 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. The Company has defined over 25 individual potential exploration targets within the Whistler – Raintree mineral system, comprising geophysical signatures similar to the known Whistler deposit.
Muddy Creek previous exploration included reconnaissance historic 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). Mapping and follow-up sampling this field season will aim to map the intrusion related mineral system to define zones of higher density quartz veining, potentially located within the upper parts of the host granitoid intrusion, with the overall objective to define targets for a future follow-up drilling program.
