Canada One Mining Corp. (TSXV: CONE,OTC:COMCF) (OTC Pink: COMCF) (FSE: AU31) (‘Canada One’ or the ‘Company’) is pleased to report high-grade gold results, accompanied by copper and silver values, from the Reco target at the Copper Dome Project, (‘Copper Dome’, ‘Project’ or ‘Property’) located adjacent to the Hudbay Minerals Inc. producing Copper Mountain Mine, Princeton, B.C.

Reco Target Sampling
In the fall of 2025, the geological team visited the Reco target, a previously known showing, and established seven new geological stations and collected four fresh rock samples (C0066668-C0066671). The two highest-grade samples collected from Reco were C0066670 (9.96 g/t Au, 9.62 g/t Ag, 0.78% Cu) and C0066671 (8.17 g/t Au, 6.83 g/t Ag, 1.75% Cu). Both samples returned elevated iron values, with sample C0066670 recording the highest iron content of the 2025 program at 12.75% Fe, reflecting intense iron oxide alteration and the potential weathering of significant sulphide mineralization at the target.
Reco is located approximately 1.8 km SSE of the Friday Creek potassic zone. Assay results from Friday Creek, also collected during the fall 2025 program, are pending release.
Peter Berdusco, President and CEO of Canada One, commented: ‘The presence of high-grade gold at Reco, part of the Copper Dome Project, significantly strengthens Canada One’s exploration thesis. The gold target sits strategically between our primary porphyry targets at Copper Dome, and the presence of near-surface gold is particularly promising given how porphyry systems often generate economically meaningful flanking gold zones—enhancing both the district-scale potential and the strategic value of our project portfolio.’
Significance of Results
Results from the Reco target meaningfully expands the Copper Dome opportunity from a ‘copper-porphyry only’ story into a broader multi-commodity mineral system that also includes a compelling high-grade, potentially near-surface, gold-silver-copper target. The standout grab samples are particularly encouraging, as such grades can signal a robust hydrothermal event capable of generating economically meaningful high-grade shoots on the margins of, or structurally linked to, porphyry centers.
Strategically, Reco’s location between key porphyry targets raises the possibility that this gold-bearing structure could represent a flanking zone or structurally focused expression of the same district-scale system, improving drill targeting and increasing the project’s potential value by adding higher-grade upside and development optionality beyond bulk-tonnage porphyry copper alone.
While rock samples are inherently selective and not necessarily representative of average grade, results of this tenor strongly justify systematic follow-up to define continuity, true width, and controls on mineralization.
Reco Planned Follow-up
Building on these promising results, the company plans to advance exploration at the target in 2026 through a larger-scale prospecting and mapping program. Additional rock sampling will help better define the extent of known mineralization, while detailed structural mapping will support interpretation of potential gold sources as they relate to the surrounding porphyry targets.
Geological Discussion
Reco was investigated in 2025 to locate and accurately geo reference historical workings and mineral showings. According to the MINFILE record, the target was explored as early as 1907, when a 167-metre-long adit was driven beneath vein outcrops between 1907 and 1909.
Reco is hosted within fine-grained volcanic and volcano sedimentary rocks of the Nicola Group, including andesite and cherty tuffs. Intense silicification was documented, along with strong iron oxidation and sericitization of the host rocks. Pyrite and copper oxide minerals are common, with localized development of chalcopyrite stringers. The observed alteration assemblage and sulphide mineralogy are consistent with a phyllic alteration domain.
Reco consists of a caved historical adit, with extensive exposure of a volcanic wall rock resulting from historical manual scree removal. Mineralization occurs as intensely oxidized, sulphidic calcite vein material hosted within a shear zone approximately 2-3 m wide. The vein and shear zone are steeply dipping and strike NE-SW. Structural measurements collected in 2025 indicate an orientation of 210°/71°, while historical measurements report orientations of 005°/78° and 038°/80°. The vein has been traced on surface for approximately 120 m and ranges from 0.1 to 1.8 m in width.
The vein is interpreted to have infilled a brittle fault zone, as evidenced by shattered host rock and the presence of gouge material adjacent to the vein. Intense supergene alteration of the wall rock is expressed as pervasive goethite and jarosite development at the target.

Quality Assurance / Quality Control (QAQC)
All rock samples were collected from the fall 2025 fieldwork program and were submitted to ALS Geochemistry – Kamloops to be analyzed for gold and platinum group elements (PGM-ICP24 50 g fire assay), and multi-element geochemistry, including elements Cu, Pb, Zn, Co, and Ag (method ME-MS61).

About The Copper Dome Project
Copper Dome is located in the lower Quesnel Trough porphyry belt, one of British Columbia’s most prolific mining districts. The Project directly adjoins Hudbay Minerals Inc.’s producing Copper Mountain Mine to the north, which the company reports as having Proven and Probable Reserves of ~367 Mt at 0.25 % Cu, 0.12 g/t Au, and 0.69 g/t Ag (Hudbay Minerals Inc., 2023)*. Multiple mineralized zones have been identified across the Property, with historical drilling confirming high-grade copper associated with northeast-trending structures similar to those hosting mineralization at Copper Mountain.
The technical and scientific information regarding the adjacent Copper Mountain Mine is sourced from Hudbay Minerals Inc.’s published reports. Mineralization at Copper Mountain should not be considered indicative of the mineralization on the Copper Dome Project.
Copper Dome benefits from excellent infrastructure, enabling year-round access, cost-efficient exploration, and a stable, low-risk jurisdiction.
Historical Work Completed
Geophysics: 51 km of induced polarization (IP); airborne magnetic and electromagnetic (EM) coverage over ~50% of the Property
Sampling: 2,253 soils and 378 rocks collected
Drilling: 8,900+ m of diamond drilling
Trenching: Over 1 km excavated
With a five-year drill permit in place, the Company is focused on advancing the Copper Dome toward drill-ready target definition.
