‎About XXIX Metal Corp‎.

XXIX is advancing its Opemiska and Thierry Copper projects, two significant Canadian copper assets. The Opemiska Project, one of Canada's highest-grade open pitable copper deposits, spans 21,333 hectares in Quebec's Chapais-Chibougamau region, with strong infrastructure and nearby access to the Horne Smelter. An October 2025 Preliminary Economic Assessment outlined a 12,500 tpd open pit operation over a 17-year mine life, generating an after-tax NPV8% of $505M, IRR of 27.2%, and a 2.3-year payback period ($4.35/lb copper price, $3,000/oz gold price, $30/oz silver price). The Thierry Project hosts the K1 (near-surface) and the past-producing K2 (underground & surface) zones (see XXIX news release dated October 1, 2024 for details regarding resources). Thierry has significant infrastructure in place including an all-season road, an airport within 5km, a provincial power grid within 8km, and nearby rail. With these two high-potential projects, the Company has solidified its position as a key player in the Canadian copper sector and has established itself as one of Eastern Canada's largest copper developer.

Forward-Looking Statements

The reader is advised that the Preliminary Economic Assessment (PEA) summarized in this news release is intended to provide only an initial, high-level review of Opemiska's economic potential. The PEA mine plan and economic model include numerous assumptions and the use of inferred mineral resources. Inferred mineral resources are considered to be too speculative to be used in an economic analysis except as allowed for by NI 43-101 in PEA studies. There is no guarantee that inferred mineral resources can be converted to indicated or measured mineral resources, and as such, there is no guarantee Opemiska's economics described herein will be achieved. XXIX may be eligible for Clean Technology Manufacturing Investment Tax Credit (CTM-ITC). This legislation has been enacted on June 20, 2024. There is no guarantee the Company will be able to access the CTM-ITC.

This news release contains certain forward-looking statements, including statements about the Company's belief that Opemiska has potential for continued growth, various cost, price and production assumptions used to inform the PEA, and outstanding risk factors, including Opemiska's proximity to the Town of Chapais, Historical Assay validation, Geotechnical considerations of open stopes in the eastern pit wall, the Venture sill, the Gwillim fault, host rock competency and Historical Stope Modeling.
