Core Viewpoint - U.S. GoldMining Inc. has partnered with Ausenco Engineering Canada ULC to conduct a Preliminary Economic Assessment (PEA) for the Whistler Gold-Copper Project, aiming to evaluate the potential for a standalone open-pit mining operation in Alaska [1][3]. Company Overview - U.S. GoldMining Inc. is focused on the exploration and development of the Whistler Gold-Copper Project, which is 100% owned by the company and located 105 miles (170 kilometers) northwest of Anchorage, Alaska. The project encompasses several gold-copper porphyry deposits and exploration targets across approximately 53,700 acres (217.5 square kilometers) of State of Alaska Mining claims [4]. Project Details - The PEA will assess the Whistler mineral resource estimate, which currently includes 6.48 million ounces (Moz) of gold equivalent (AuEq) in the indicated resource category and 4.16 Moz AuEq in the inferred resource category. The project is expected to benefit from near-surface, higher-grade core material during the initial years of production [6]. - The PEA will utilize an updated mineral resource estimate that incorporates 2024 drilling data, which was not included in the previous estimates. Additionally, metallurgical testing is being conducted by Base Metallurgical Laboratories Ltd. [6]. Consulting Partnership - Ausenco was selected as the principal consulting firm for the PEA after a comprehensive bidding process involving 13 firms.
