U.S. GoldMining Highlights Exploration Potential at the Muddy Creek Mineral System, Including Historic High Grade Rock Grab Samples up to 111.50 g/t Au, Whistler Gold-Copper Project, Alaska

Core Insights - U.S. GoldMining Inc. is advancing exploration at the Muddy Creek area of its Whistler Gold-Copper Project in Alaska, identifying significant exploration potential across three mineral systems [1][4][19] - The company is conducting a preliminary economic assessment (PEA) alongside exploration activities, aiming to enhance its geological understanding and identify high-priority targets for future drilling [1][4] Exploration Targets - The Muddy Creek mineral system covers an area of approximately 6 km x 4 km, characterized by a strong gold geochemical signature related to intrusive processes [6][10] - Historic exploration has revealed promising results, including 73 rock samples with grades exceeding 1 gram per tonne (g/t) gold, with peak values reaching 111.50 g/t Au [6][12] - Soil sampling has also indicated significant gold presence, with 104 samples returning values greater than 0.10 g/t Au, and peak values of 5.29 g/t Au in the central Muddy Creek zone [6][10] Historical Context - Previous exploration efforts included reconnaissance sampling and a small drilling program, which confirmed low-grade gold mineralization at the margins of the Muddy Creek system [6][11] - The highest-grade areas of the Muddy Creek system have yet to be drilled, indicating potential for discovering higher-grade mineralization in future exploration [12][13] Future Plans - The company is planning phased exploration programs to systematically test the highest-ranking targets, including Muddy Creek, with potential drilling commencing in the summer field season [4][13] - Detailed geological mapping and additional surface geochemical sampling are required to further define the geometry of the intrusive phases and identify areas with the highest mineralization potential [10][12]
