The Company’s diversified holdings include 100%-owned projects with estimated mineral resources of over 1.2 billion pounds of copper in Measured and Indicated ("M&I") categories and a further 0.5 billion pounds in the Inferred category. In addition, the Company has a strategic ownership of approximately 79% of U.S. GoldMining Inc. ("U.S. GoldMining"), that owns the Whistler Gold-Copper Project in Alaska that hosts over 1 billion pounds of copper in estimated Indicated resources, and over 300 million pounds copper in estimated Inferred resources, alongside gold and silver.

GoldMining’s portfolio includes over a dozen projects located in tier-one mining jurisdictions, many of which contain multi-million-ounce estimated gold resources accompanied by substantial copper mineralization. The Company’s aggregated estimated mineral resources include approximately 12.4 million gold equivalent ounces in the M&I categories, and a further 9.1 million gold equivalent ounces in the Inferred category. The Company’s estimated mineral resources are exclusive of those reported by U.S. GoldMining. GoldMining owns approximately 9.9 million shares of U.S. GoldMining (Nasdaq: USGO), representing an approximate 79% ownership, with a market value of approximately CAD$119 million, based on the closing price of such shares on July 18, 2025.

Alastair Still, CEO of GoldMining, commented: "Copper is not only a critical metal for the energy transition, it is now a matter of national interest for governments across the Americas. GoldMining is uniquely positioned with a diversified portfolio that includes multiple resource-stage gold and gold-copper projects containing significant copper resources, including our interest in the Whistler Gold-Copper Project in Alaska, as well as the La Mina, Titiribi and Yarumalito projects which comprise our Colombian assets. The recent price appreciation of copper, gold and silver highlights the embedded, and in many ways underappreciated, value within our portfolio. Thus, we believe GoldMining offers shareholders a compelling exposure to upside potential for both gold and copper as we advance our projects and as demand for these critical metals accelerates globally."
