XXIX Intersects 32.7 g/t Gold, 81.4 g/t Silver and .95% Copper over 7.5 Metres at Cooke

Highlights:

• 32.7 g/t gold, 81.4 g/t silver and 0.95% copper over 7.5 metres in hole COR-26-60, including:
  • 142.4 g/t gold over 0.9 metres, and
  • 43.2 g/t gold over 1.0 metre, and
  • 31.8 g/t gold over 1.0 metre
• Seven intervals above 10 g/t gold returned from the first 10 holes of the winter drill program
• Cooke lies approximately 2 kilometres east of the envisioned Opémiska open pit and remains outside any currently defined resource
• Results continue to define two mineralized zones and support continuity of mineralization
• Copper values in several intercepts suggest potential for meaningful by-product credits
• Remaining assays from 8 additional holes are pending from the current Cooke drill program

Toronto, April 27, 2026 - XXIX Metal Corp.‎. (TSXV: XXIX) (OTCQB: QCCUF) (FSE: 5LW0) ("XXIX" or the "Company") is pleased to report additional drill results from the Cooke Zone, located approximately 2 kilometres east of the Company's envisioned Opémiska open pit.

The latest results continue to demonstrate that Cooke hosts high-grade gold-silver-copper mineralization and support the potential for Cooke to emerge as a satellite deposit within the broader Opémiska development scenario. Importantly, Cooke is a past-producing mine with no current NI 43-101 resource, giving XXIX a clear opportunity to add near-surface ounces and enhance the scale and flexibility of the Opémiska project.

XXIX is reporting results from the first 10 holes of its winter drill program at Cooke. From January 7 to March 23, 2026, the Company completed 3,315 metres of drilling in 18 holes using one rig. Combined with the fall program, XXIX has now completed a total of 9,225 metres at Cooke. The objective of the program is to evaluate Cooke as a potential second open pit that could complement the envisioned Opémiska operation.

Across the first 10 holes, the Company intersected seven intervals grading more than 10 g/t gold. The standout intercept came from hole COR-26-60, which returned 32.72 g/t gold, 81.41 g/t silver and 0.95% copper over 7.5 metres, including 142.4 g/t gold over 0.9 metres, 43.2 g/t gold over 1.0 metre, and 31.8 g/t gold over 1.0 metre. Hole COR-26-60 also returned a separate interval of 2.25 g/t gold over 17.0 metres higher in the hole.

These results continue to support the presence of two mineralized zones at Cooke and reinforce management's view that the area has the potential to grow into a meaningful addition to the broader Opémiska district. With Cooke located close to the contemplated Opémiska infrastructure footprint, success here could translate into incremental feed, improved mine plan flexibility, and greater overall development optionality.

"Cooke is a past-producing mine located near our envisioned Opémiska open pit, and these latest intercepts strengthen the case for advancing it toward a maiden resource. While the gold distribution is variable, the consistency of the two mineralized zones and the strength of the higher-grade intervals support follow-up drilling at tighter spacing as we work to unlock additional value from the district," said Guy Le Bel, CEO of XXIX.

Cooke remains one of the clearest district-scale growth opportunities within Opémiska. The extension of two parallel mineralized zones from early drilling supports the potential to define a maiden resource, which could add scale and flexibility as XXIX advances Opémiska along the path toward its next mineral resource update and pre-feasibility work. The Company expects assay results from the remaining 8 holes shortly and is continuing to refine its geological interpretation ahead of planning the next phase of drilling.

XXIX's geological team is continuing to refine its interpretation and understanding of mineralization and expects to define a next phase of drilling aimed at supporting a maiden resource estimate ahead of the commencement of the PFS at Opémiska.

Quality Control and Assurance

All samples (NQ core) are logged and cut in two at the Company's secure facility in Chapais, under the supervision of Ahcene Gaoui, P.Geo., project geologist. The samples are sent to Agat Laboratories in Val-d'Or by a secure transport. One standard and one blank are inserted in every 50 samples, the blank always in a mineralized zone.‎

The analytic method used is fire assay, trace Au, AAS finish and Fire assay, Au grade with gravimetric finish for over limit results. We use Aqua regia disgest, metals package ICP OES finish for Cu and Ag with ICP-MS finish for over limit results.

About XXIX Metal Corp‎.

XXIX is advancing its Opemiska and Thierry Copper projects, two significant Canadian copper assets. The Opémiska 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.
