, /PRNewswire/ - U.S. GoldMining Inc. (NASDAQ: USGO) ("U.S. GoldMining" or "the Company") is advancing the Whistler Gold-Copper Project ("Whistler" or "the Project"), located in Alaska, U.S.A. As the Company progresses its previously announced initial assessment study ("PEA") (see news release dated June 9, 2025), it is closely tracking consensus and spot metal prices, and is encouraged by the price of copper which has risen approximately 14% over the past month, and is up approximately 20% compared to the same time last year. 

Tim Smith, Chief Executive Officer of U.S. GoldMining, commented: "We believe that the existing gold-copper-silver deposits already delineated at the Project, combined with district-scale exploration potential and proximity to existing and planned future infrastructure in south-central Alaska, makes the Project stand out among other American gold-copper projects. Whistler is further poised to benefit from recent increases in the price of gold, copper and silver, the three metals contained within the Whistler mineral resources. Current federal policy further emphasizes the advantage for U.S.-based gold-copper developers such as U.S. GoldMining, and as an American domiciled company with a project located in the Tier 1 jurisdiction of Alaska, the Company is positioned to benefit as domestic copper supply becomes increasingly vital. We believe U.S. GoldMining offers investors a compelling opportunity to gain exposure to both gold and copper upside as demand accelerates."

Over the past six months, the U.S. federal administration has begun to implement initiatives to speed up the permitting processes for potential future U.S. mine development projects which are crucial to securing domestic resource security. Additionally, the Trump administration's action on trade policy, including the recent announcement of a proposed 50% tariff on foreign copper imports into the United States on July 8, 2025, which is aimed at strengthening America's critical minerals independence, sent the price of copper to all-time highs. For U.S. GoldMining, it marks a potential inflection point for the Company's flagship Project, with district-scale exploration potential and a large copper-gold-silver mineral resource in one of America's most prospective and mining-friendly jurisdictions, Alaska.

The Whistler Gold–Copper Project: A U.S.A. Based Critical Metals Project

The Project, located just 100 miles from the main population center of Anchorage, in Alaska, (see Figure 1), is estimated to contain mineral resources of over 1 billion pounds ("Blbs") of copper, in addition to 3.93 million ounces ("Moz") gold and almost 19 Moz silver in the Indicated category (see Table 1), in addition to 0.3 Blbs copper, 3.31 Moz gold and 11.5 Moz silver in the Inferred category¹.
