U.S. GoldMining Inc. reports developments in mineral exploration and project evaluation for its 100%-owned Whistler Gold-Copper Project in Alaska. Company updates focus on gold-copper porphyry targets, diamond core drilling programs, geochemical and geophysical target generation, and technical disclosure tied to the project's initial economic assessment.
Recurring news also covers S-K 1300 and NI 43-101 technical reports, project-development leadership additions, permitting and infrastructure context for Whistler, and the company's relationship with majority owner GoldMining Inc. The issuer operates as a single-segment mineral exploration company focused on mineral properties.
U.S. GoldMining (NASDAQ: USGO) has provided an update on its Whistler Gold-Copper Project in Alaska, highlighting significant exploration potential across three distinct mineral systems. The project, located 100 miles west of Anchorage, spans 53,700 acres and includes the Whistler-Raintree, Island Mountain, and Muddy Creek systems. Recent drilling successes include a record 652.5-meter intercept grading 1.00 g/t gold equivalent at the Whistler Deposit and a new discovery near Raintree West yielding 138.0 meters at 0.99 g/t gold equivalent. The company plans to develop phased exploration programs starting this summer while simultaneously conducting an initial economic assessment. The project benefits from proximity to infrastructure and favorable mining jurisdiction status in Alaska.
U.S. GoldMining Inc. (NASDAQ: USGO) has initiated metallurgical testwork for its Whistler Gold-Copper Project in Alaska, located 105 miles northwest of Anchorage. The testwork will support the project's preliminary economic assessment (PEA) and aims to develop an optimized process flowsheet for metal recovery.
The company has engaged Base Metallurgical Laboratories (BaseMet) to conduct comprehensive testing, including:
- Preparation of variability and master composites from 2023-2024 drill core samples
- Feed characterization and detailed mineralogy
- Comminution testing for crushing and grinding
- Sulphide flotation testing for chalcopyrite concentrate
- Gravity gold and cyanide leaching tests
Previous metallurgical tests showed promising results with gold recovery at 70% and copper recovery at 83% through conventional flotation, producing a high-quality copper concentrate with gold and silver credits. The company aims to optimize these recovery rates through the current testing program.
GoldMining Inc. (TSX: GOLD, NYSE: GLDG) has identified significant antimony mineralization at its 100% owned Crucero Project in Peru, co-existing with previously established gold deposits. The project contains an indicated resource of 30.65 million tonnes at 1.0 g/t Au (993,000 oz gold) and an inferred resource of 35.78 Mt at 1.0 g/t Au (1,147,000 oz gold).
Notable drill intercepts include 44.37 g/t AuEq over 7 metres and 2.79 g/t AuEq over 79 metres. The discovery gains significance as antimony prices have surged to approximately US$55,250 per tonne, up from US$11,600 at the start of 2024. The database contains assay data for 72 drill holes and 657 trench assays, including over 15,000 gold assays and 10,000 antimony assays.
