U.S. GoldMining Discovers New High Grade Zone at Raintree Prospect, Whistler Gold-Copper Project, Alaska

Core Viewpoint - U.S. GoldMining Inc. has announced promising assay results from its 2024 diamond core drilling program at the Whistler Gold-Copper Project in Alaska, highlighting significant high-grade gold and silver mineralization at the Raintree Deposit, which could enhance the project's resource potential [1][5][6]. Drilling Results - The drilling program included six diamond core holes totaling 4,006 meters, with two holes specifically targeting the Raintree Deposit [8]. - Drill hole WH24-05 intercepted multiple zones of high-grade gold and silver polymetallic mineralization, with peak values of 7.15 g/t Au and 189 g/t Ag, along with base metal values of up to 5.4% Zn and 3.6% Pb [6][21]. - A main zone composite intercept of 138.0 meters at 0.99 g/t AuEq was reported, including higher-grade intervals of 26 m at 1.48 g/t AuEq and 34 m at 1.65 g/t AuEq [7][21]. Geological Insights - The Raintree Deposit features both porphyry-style Au-Cu-Ag mineralization and overprinting polymetallic vein-style mineralization, contrasting with the Whistler Deposit, which primarily consists of porphyry-style mineralization [12]. - The geological setting of the Raintree Prospect is characterized by small intrusive diorite porphyry bodies hosted within andesite lavas and related volcaniclastic rocks, indicating a potentially rich mineral system [11]. Future Plans - The company plans to conduct follow-up drilling in the summer of 2025 to further explore and delineate the newly discovered mineralization at the Raintree Deposit [6][18]. - All exploration results and geological datasets from the 2024 drilling season are being compiled to update exploration target prioritization for the upcoming drilling season [8]. Resource Estimates - The Raintree component of the Project mineral resource estimate includes both open pit constrained and underground delineated deposits, with significant indicated and inferred resources reported [10][9]. - The current mineral resource estimate for the Whistler Project comprises 294 million tonnes at 0.68 g/t AuEq for 6.48 million ounces AuEq indicated, plus 198 million tonnes at 0.65 g/t AuEq for 4.16 million ounces AuEq inferred [30].
