Toronto, Ontario — February 27, 2026 — Leads & Copy — XXIX Metal Corp. (TSXV: XXIX) (OTCQB: QCCUF) (FSE: 5LW0) has announced initial drill results from the Cooke Zone, located approximately 2 kilometers east of the company’s envisioned Opemiska open pit.
The drilling program, targeting about 10,000 meters across the Cooke and Saddle Zones, focused on the near-surface crown pillar to test the North and South Zones over a 700-meter strike length. Results confirm gold-copper-silver mineralization and highlight the potential for Cooke to provide incremental mill feed to the Opemiska project.
Drilling identified at least two parallel mineralized zones, intersected in every hole. Cooke, a past-producing mine without a current NI 43-101 resource, represents a growth opportunity within the Opemiska district. Delineation of a mineralized crown pillar at Cooke could strengthen the overall Opemiska development plan as the company advances the project toward an updated Mineral Resource Estimate (MRE) to support a Preliminary Feasibility Study (PFS).
According to Guy Le Bel, CEO of XXIX, the initial holes at Cooke validate the opportunity to add high-value, near-surface ounces and copper to the Opemiska project. The company plans tighter-spaced drilling to advance Cooke toward a maiden resource.
Mineralization at Cooke differs from the Springer and Perry zones, which are characterized by larger veins. Cooke’s mineralization is hosted within two shear zones containing smaller veins and veinlets, producing higher-grade intersections and greater variability. Drilling in the Chibougamau copper zone intersected high copper values.
The company believes these results justify a follow-up program with narrower drill spacing to support a potential maiden MRE at Cooke.
Key drill results include 3.63 g/t gold, 3.50 g/t silver and 0.27% copper over 6.40 metres from 61.2 metres (COR-25-38).
XXIX is advancing its Opemiska and Thierry Copper projects. The Opemiska Project, located in Quebec’s Chapais-Chibougamau region, has an October 2025 Preliminary Economic Assessment outlining a 12,500 tpd open pit operation over a 17-year mine life. The Thierry Project hosts the K1 and K2 zones and has infrastructure in place, including an all-season road and nearby rail.
XXIX 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.
True thickness are unknown.
All samples (NQ core) are logged and cut in two at the company 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 digest, metals package ICP OES finish for Cu and Ag with ICP-MS finish for over limit results.
Denis McNichols, P.Geo and géo., Vice President Exploration for XXIX Metal, a Qualified Person, as defined in “National Instrument 43-101, Standards of Disclosure for Mineral Projects, has reviewed and approved the technical information contained in this release.
