CANADA ONE PROVIDES EXPLORATION REVIEW OF COMBINATION CREEK ZONE, COPPER
DOME PROJECT
Vancouver, B.C., October 22, 2025 - Canada One Mining Corp. (“Canada One” or the “Company”)
(TSXV: CONE) (OTC: COMCF) (FSE: AU31) is pleased to provide a n exploration review of the
Combination Creek Zone at its 100% owned Copper Dome Project , (“Copper Dome”, “Project” or
“Property”), Princeton B.C.

Peter Berdusco, President and CEO of the Company commented: “The Combination Creek zone
provides compelling evidence of a mineralizing system extending south from Copper Mountain.
Historical work has confirmed strong copper grades across multiple drill holes. The scale of veining,
consistent copper mineralization, a nd proximity to the Copper Mountain mine all suggest we may be
exploring within the broader halo of a porphyry centre. As we advance our exploration model, we see
clear potential to outline a porphyry-style target next to an operating mill.”
Combination Creek Review
The Combination Creek Zone located in the northeast corner of the Copper Dome Project (See Figure
1: Location Map of the Copper Dome Project) shows stockwork veining associated with altered volcanic
and sedimentary rocks adjacent to the Copper Mountain stock. Two historical mineral occurrences have
been identified in this area – The Marquis of Lorne and the Skagit 1 Fraction Zone, both of which exhibit
strong structural controls on mineralization and sulphide development. Historical mapping and
descriptions indicate intense alteration characterized by assemblages of epidote –chlorite–Fe oxide ±
albite, with pyrite –chalcopyrite and associated malachite oxidation. The presence of albite and
chalcopyrite within the traditionally propylitic chlorite –epidote-pyrite alteration front suggests that this
zone may represent a transition toward a higher-temperature potassic domain of a porphyry system.
The best mineralization in the Combination Creek zone drilled to date is found in a 70 to 100m wide
section of Nicola volcanics extending at least 250m east west, bounded to the north by the Copper
Mountain Stock and to the south by a coarse pink feldspar porphyry syenite dyke.
Selective Historical Drill Results
Drilling by the Company in 2010, 2011 and 2012 in the Combination Creek Zone returned the following
highlighted intercepts (See Figure 2: Map of Combination Creek Zone with Selected Historical Drill Hole
Locations and Results (Cu):

• DDH PT-10-06: 19.50m of 0.34% Cu starting at 106.50m and 3.00m of 0.93% Cu starting at
247m.
• DDH PT-11-16: 10.00m of 0.65% Cu starting at 231m and 25.31m of 0.21% Cu starting at 3.69m.
• DDH PT-11-18: 68.25m of 0.14% Cu starting at 3.28m, including 6.00m of 0.25% Cu starting at
74m, and 6.00m of 0.29% Cu starting at 313m.
• DDH PT-11-21: 69.00m of 0.21% Cu starting at 18.00m, including 12.00m of 0.50% Cu starting
at 99.00m.
• DDH PT-12-26: 20.00m of 0.64% Cu starting at 141.00m, including 14.00m of 0.86% Cu starting
at 145.00m.
Mineral Occurrences of the Combination Creek Zone
Marquis of Lorne
The Marquis of Lorne prospect is underlain by the eastern facies of the Upper Triassic Nicola Group,
composed mainly of mafic augite and hornblende porphyritic pyroclastics and flows. These are intruded
by Early Jurassic Copper Mountain and Lost Horse intr usions—diorite, monzonite, and locally
pyroxenite and gabbro. Mineralization occurs in shear zones within andesitic and cherty tuffs, close to
the Copper Mountain stock, typically within 50m of its margin.
The best -defined shear zone, located 40m south of the stock, hosts strong limonite, jarosite, and
malachite alteration, with historical grab samples returning up to 1.97% Cu and 10.7 g/t Ag, and chip
samples averaging 0.563% Cu and 3.6 g/t Ag over 5 m. A parallel shear zone 60m southwest returned
1.53% Cu and 17.1 g/t Ag in grab samples. Additional narrow shears 200 m west -southwest show
traces of chalcopyrite and malachite with albite alteration.
Skagit 1 Fraction
The Skagit No. 1 prospect shares similar geology with Marquis of Lorne, being hosted in the Upper
Triassic Nicola Group volcanic rocks intruded by the Copper Mountain and Lost Horse intrusions. The
occurrence consists of several sulphid e-rich shear zones and fractures in andesitic tuff and minor
volcanic sediments, located within 60m of the Copper Mountain stock. Mineralization includes bornite,
chalcopyrite, and malachite, with historical surface chip samples averaging 0.36% Cu and 2.3 g/t Ag
over 10 m, and trench samples grading 0.28% Cu and 2.9 g/t Ag over 30 m.1
The property was mapped and sampled by Newmont (1970 –71), Kidd Creek Mines (1983), and later
Targa Resources (1986). After limited activity for two decades, the Company conducted a major
exploration program in 2010, including 26.4 km of induced polarization and magnetometer surveys plus
5,732 metres of diamond drilling in 22 holes. Drilling intersected 0.21% Cu over 69 metres (DDH PT11-
21), and geophysical data revealed a strong (>35 ms) chargeability anomaly in the Nicola volcanics
south of the Copper Moun tain stock, suggesting potential for porphyry -style copper -gold
mineralization.1

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.
