Canada One Year-End Review 2025

Vancouver, British Columbia--(Newsfile Corp. - December 22, 2025) - Canada One Mining

Corp. (TSXV: CONE) (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

Q1 2026 - Rock sample assay results

January 2026 - Vancouver Resource Investment Conference

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.
