XXIX EXPANDS OPEMISKA'S REGIONAL FOOTPRINT BY ADVANCING THE PLUTO PROPERTY OPTION

XXIX Metal Corp. has issued 287,403 common shares to Germanium Mining Corp., completing the share issuance required under the option agreement. The option agreement provides XXIX with the right to acquire a 100-per-cent interest in the Pluto property, located approximately 10 kilometres from the company's flagship Opemiska project in Quebec's Chapais-Chibougamau region. The option agreement was previously announced on June 23, 2026.

Highlights:

• Pluto adds copper-gold-silver exploration exposure near Opemiska without changing XXIX's core focus on Opemiska and Thierry;
• XXIX views the broader Opemiska district as highly prospective for copper-gold mineralization, with Pluto adding new exploration targets that could benefit the Opemiska camp;
• Recent forestry road development has improved access and may reduce the cost of initial fieldwork;
• Historical work indicates copper-gold-silver potential, which requires modern validation;
• XXIX plans to compile historical data, complete reconnaissance mapping and prospecting, rank targets, and assess whether trenching or drilling is warranted.

The shares were issued at a deemed price of 17.4 cents per share, based on the 20-day volume-weighted average trading price of the company's common shares on the TSX Venture Exchange ending Sept. 8, 2026, in satisfaction of the $50,000 share consideration required under the option agreement. The shares are subject to an applicable statutory hold period of four months and one day from the date of issuance.

Following the issuance of the shares, the company's remaining obligation under the option agreement is to complete exploration expenditures of at least $250,000 on the Pluto property on or before Dec. 31, 2028.

Pluto complement to XXIX's strategy in the Chapais-Chibougamau district

XXIX's strategy remains centred on advancing Opemiska and Thierry. Pluto is intended to be a complementary addition to that strategy rather than a new development focus.

Pluto's proximity to Opemiska is relevant from a regional exploration and logistics perspective. If field validation supports historical information, Pluto could provide additional early-stage exploration potential around the Opemiska project. At this stage, Pluto is not part of the Opemiska mineral resource or development plan and will be advanced only if results justify further work.

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-pittable 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 net present value (discounted at 8 per cent) of $505-million, an internal rate of return of 27.2 per cent and a 2.3-year payback period (copper price of $4.35 per pound, gold price of $3,000 per ounce and silver price of $30 per ounce). The Thierry project hosts the K1 (near-surface) and the past-producing K2 (underground and surface) zones (see XXIX's 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 kilometres 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 developers.
