Vancouver, British Columbia--(Newsfile Corp. - August 10, 2026) - TNR Gold Corp. (TSXV: TNR) ("TNR", "TNR Gold" or the "Company") is pleased to advise that McEwen Inc. ("McEwen") has announced an update on the Los Azules copper, gold and silver project in San Juan, Argentina. TNR holds a 0.4% net smelter returns royalty ("NSR Royalty") (of which 0.04% of the 0.4% NSR Royalty is held on behalf of a shareholder) on the Los Azules Copper Project. The Los Azules project is held by McEwen Copper Inc. ("McEwen Copper"), which is 46.3% owned by McEwen. An extract from a news release issued by McEwen on August 5, 2026, stated: "Significant Ownerships McEwen Copper McEwen owns a 46.3% equity stake in McEwen Copper. The 2025 Feasibility Study for McEwen Copper's Los Azules project confirmed robust project economics, including initial 5-year average production of 205 ktpa of copper cathodes and a $1.71/lb C1 cash cost over a 22-year mine life. The study also identified the potential to extend the mine life by an additional 33 years under the Nuton case for a total of 55 years, with average copper cathode production of approximately 141 ktpa. The Nuton case is preliminary in nature and is not supported by Mineral Reserves. McEwen also owns a 1.25% NSR royalty on McEwen Copper's Los Azules copper project. Under the 2025 Feasibility Study base case of $4.35/lb copper, the royalty is projected to generate approximately $389.5 M of undiscounted pre-tax cash flow over the initial 22-year operating period. Under the PEA-level Nuton case, which assumes a copper price of $4.80/lb and could potentially extend the mine life by an additional 33 years, the royalty is projected to generate a further approximately $633.5 M. Based on the 2025 Feasibility study and using a recent copper spot price of $6.50/lb, McEwen's royalty is projected to generate approximately $584 M from the initial case and $860 M from the potential Nuton extension, for a combined undiscounted pre-tax royalty cash flow of approximately $1.4 B. Los Azules continued to advance toward a Final Investment Decision ("FID") during Q2, with approximately 27% of the planned FID work program deliverables completed as of June 30, 2026, and the balance targeted for completion in Q4 2026. Key activities included advancing vendor engineering for the SX/EW plant, sulfuric acid plant and crushing systems, progressing mining fleet evaluation, power supply assessment and EPCM contractor selection, and commencing construction of the access road and site camp. The Company also completed its planned H1 2026 field campaign of geotechnical, condemnation and hydrogeological drilling. During Q2, Société Générale was appointed as exclusive financial advisor for the project's debt financing process and preparations were initiated for a potential initial public offering. McEwen Copper is also reviewing an enhanced financing proposal received from European export credit agency. Management remains focused on completing the FID work program, with construction targeted to commence in early 2027 and production in 2030, subject to project financing and customary approvals."

Kirill Klip, the Company's Chief Executive Officer, stated, "We are pleased that McEwen Copper has reached this milestone following the release of the feasibility study and securing of an environmental permit for the construction and operation of Los Azules. The collaboration between McEwen Copper and International Finance Corporation (IFC), and admission to the Argentina Regime of Incentives for Investment (RIGI) could move the Los Azules copper project development closer to a construction decision. "Mining in Argentina is being recognized by the government as an integral part of its economic development plan, providing jobs and enriching local communities. The president of Argentina has introduced important government policies aimed at supporting business and unlocking the country's economic potential. "TNR Gold's vision is aligned with the leaders of innovation among automakers like Stellantis, whose aim is to decarbonize mobility, and mining industry leaders such as Rob McEwen, whose vision is 'to build a mine for the future, based on regenerative principles that can achieve net zero carbon emissions by 2038'. "Together with Rio Tinto's Venture Nuton®, McEwen Copper is exploring new technologies that save energy, water, time and capital, advancing Los Azules towards the goal of leading environmental performance. The involvement of Rio Tinto, with its innovative technology, may also accelerate realizing the potential of the Los Azules project. "The green energy rEVolution relies on the supply of critical metals like copper. Delivering 'green copper' to Argentina and the world will contribute to the clean energy transition and electrification of transportation and energy industries. "The feasibility study confirms Los Azules project as a long-life, low-cost producer of high-purity copper cathodes with strong economic returns and sustainability. It highlights the potential to create a robust leach project while reducing the environmental footprint, and greater environmental and social stewardship sets the project apart from other potential mine developments. "TNR Gold does not have to contribute any capital for the development of the Los Azules Project. The essence of our business model is to have industry leaders like McEwen as operators on the projects that will potentially generate royalty cashflows to contribute significant value for our shareholders." ABOUT TNR GOLD CORP. TNR Gold Corp. is working to become the green energy metals royalty and gold company. Our business model provides a unique entry point in the creation of supply chains for critical materials like energy metals that are powering the energy rEVolution, and the gold industry that is providing a hedge for this stage of the economic cycle. Our portfolio provides a unique combination of assets with exposure to multiple aspects of the mining cycle: the power of blue-sky discovery and important partnerships with industry leaders as operators on the projects that will potentially generate royalty cashflows to contribute significant value for our shareholders.
