Canada One Year-End Review 2025

Canada One Mining Corp. (TSXV: CONE,OTC:COMCF) (OTC Pink: COMCF) (FSE: AU31) (‘Canada One’ or the ‘Company’) is pleased to provide a review of the Company’s 2025 key accomplishments at its 100% owned Copper Dome Project, (‘Copper Dome’, ‘Project’ or ‘Property’), Princeton B.C.

2025 PROJECT HIGHLIGHTS

A five-year exploration drilling permit was granted by the British Columbia Ministry of Mining and Critical Minerals
Adjacent claim staking of Copper Dome East expanded the Project size to 7,997 ha
Acquisition of Copper Dome North, an adjacent property, expanded the Project size to 12,833 ha
Fall fieldwork program established 53 field stations with full metadata across the property
Rock samples have been sent for assaying
Copper sulphides, including bornite and chalcopyrite were observed in several rock samples
Key alteration assemblages observed are indicative of proximity to porphyry centers

Peter Berdusco, President and CEO of the Company commented: ‘2025 marked a significant step forward for the Copper Dome Project. The granting of a five-year drilling permit, combined with strategic property expansion to over 12,800 hectares, gives us both the time horizon and land position needed to properly evaluate the system. The identification of copper sulphides, including bornite and chalcopyrite, together with alteration assemblages consistent with porphyry-style mineralization, reinforces our belief that the Project has strong discovery potential. We look forward to receiving rock sample assay results and advancing the Project toward drill-ready status in 2026.’

Year-end Review

The 2025 exploration program at the Copper Dome Project represented a key advancement in the systematic evaluation of the property, highlighted by the receipt of a five-year exploration drilling permit. This permit provides the Company with a defined multi-year framework to plan and execute phased drilling programs, significantly de-risking future exploration timelines.

In parallel, the Company expanded the Project footprint through strategic staking and acquisition of adjacent claims, consolidating a contiguous land package totaling 12,833 hectares. Fall fieldwork established a robust geological foundation, including 53 fully documented field stations, and identified copper sulphide mineralization and alteration assemblages indicative of proximity to porphyry-style mineralization. Rock samples collected during the program have been submitted for assaying, with results expected to further refine geological interpretations and prioritize drill targets.

Upcoming Catalysts

January 2026 – AME Roundup 2026
March 2026 – Professional & Developers Association of Canada (PDAC) Convention
Q2 2026 onward – Further exploration activities

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 (TSX: HBM) producing Copper Mountain Mine to the north which hosts Proven and Probable Reserves of 702 million tonnes grading 0.24% Cu, 0.09 g/t Au, and 0.72 g/t Ag (hudbayminerals.com). 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 Project 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 Project toward drill-ready target definition.

* Management cautions that past results, discoveries and mineralization on Copper Mountain are not necessarily indicative of the results that may be achieved on Copper Dome.
