A project with strong potential to transform the region The Opemiska project envisions the reactivation of a historic high-grade copper mining site, with estimated investments of more than $3.5-billion over about 20 years, and a processing plant located within the municipal boundaries of Chapais to maximize local benefits. Opemiska demonstrates strong economic potential and is among Canada's most promising copper development projects. Full details for XXIX's PEA are available in the company's news release dated Oct. 21, 2025, including: Robust after-tax base case economics: $505-million after-tax NPV (net present value) (8 per cent); 27.2-per-cent after-tax IRR (internal rate of return). Using spot metal prices: $897-million after-tax NPV (8 per cent); 39.3-per-cent after-tax IRR. Rapid payback: 2.3 years on $617-million initial capital; High-grade early years: average annual production of 59 million pounds of copper, 34,000 ounces of gold and 174,000 oz of silver over the first six years; Low-cost producer: $1.03 (U.S.)/lb C1 cash cost (net of byproduct credits) during the first six years, placing Opemiska in the lower quartile of the global cost curve. The PEA further highlights significant leverage to rising copper and gold prices, with an estimated $4.4-billion in life-of-mine revenue, and identifies strong resource expansion potential, particularly at the Cooke gold zone where exploration drilling continues.

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-tonne-per-day open pit operation over a 17-year mine life, generating an after-tax NPV 8 per cent of $505-million, IRR of 27.2 per cent 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 and surface) zones (see XXIX news release dated Oct. 1, 2024, for details regarding resources). Thierry has significant infrastructure in place including an all-season road, an airport within five kilometres, a provincial power grid within eight km 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.
