Vancouver, British Columbia--(Newsfile Corp. - November 25, 2025) - Canada One Mining Corp. (TSXV: CONE) (OTC Pink: COMCF) (FSE: AU31) ("Canada One" or the "Company") is pleased to provide an exploration update following the Phase 2 exploration program conducted at its 100% owned Copper Dome Project, ("Copper Dome", "Project" or "Property"), Princeton B.C.2025 FIELD PROGRAM HIGHLIGHTS Crews established 53 field stations with full metadata across the property, systematically documenting geological observations to contextualize mineral showings in relation to property-scale and regional geology.A total of 29 rock samples were collected during the first phase of exploration and have been delivered to the laboratory for analysis.Copper sulphides, including bornite and chalcopyrite, were observed in several rock samples. Assay results are pending.Key alteration assemblages observed are indicative of proximity to porphyry centers. Peter Berdusco, President and CEO of the Company commented: "We are thrilled with the Phase 2 exploration work, which identified numerous samples containing visible copper sulphide minerals. The Friday Creek zone emerged as a standout area of interest, and additional work is planned to further evaluate its mineralization footprint and potential within the broader Copper Dome system. Observing bornite in hand sample is a strong indicator of potential porphyry systems, and the project's proximity to the Copper Mountain Mine only strengthens the geological narrative. The visible copper mineralization and potassic alteration signatures observed in these samples provide Canada One with a solid foundation to advance exploration and refine its 2026 objectives at the Copper Dome project."Exploration SummaryCrews completed the Phase 2 field program at the Copper Dome Project, with a primary focus on visiting historic MINFILE occurrences and applying modern exploration insight to reassess legacy data and descriptions. All documented MINFILE locations were successfully visited, and 53 field stations were collected with full metadata at each site. A total of 29 rock samples were submitted for analysis at ALS Geochemistry - Kamloops, and the Company expects an approximate four-week turn around on results. Historic workings and related infrastructure were mapped, documented, and georeferenced, with access conditions recorded for each location (See Figure 1).The Company is encouraged by early field observations, which include chalcopyrite stringers, mineralized breccia cement, and bornite clots and stringers (see Figures 2-4).

Alteration across the zone is similarly encouraging, with moderate to strong K-feldspar and biotite alteration commonly observed near the copper sulphides. This alteration and mineralization assemblage is a recognized indicator of prospective porphyry copper systems, suggesting that the outcrop may lie within the system's central potassic zone.The discovery of in-situ bornite at the Friday Creek zone is extremely encouraging. Bornite is a copper-bearing sulphide mineral (chemical formula Cu₅FeS₄, containing ~63% copper by mass), and its presence is commonly associated with proximity to porphyry centers. Bornite was observed across an approximate 150 m by 150 m area, highlighting a meaningful footprint of a high-temperature potassic zone and demonstrating strong potential for a porphyry system near surface. At Friday Creek, alteration was mapped over a vertical extent of roughly 100 meters, extending downslope to the valley bottom, where the strongest alteration intensity was recorded.Figure 2: Rock sample (2025JG0197), collected from the Friday Creek Zone, comprises a diorite intrusion exhibiting K-feldspar-biotite alteration and internal brecciation, hosting semi-massive bornite mineralization with associated stringers.To view an enhanced version of this graphic, please visit:https://images.newsfilecorp.com/files/10074/275866_canadaone_figure2.pngBornite at the Friday Creek Zone occurs in several styles. A diorite unit was observed with moderate intensity K-feldspar alteration surrounding bornite stringers exhibiting an internally brecciated texture. The K-feldspar may represent an alteration envelope around the chaotic bornite vein swarm (See Figure 2).Figure 3: Rock sample (2025JG0001), collected from the Friday Creek Zone, shows a brecciated pegmatite with hydrothermal breccia infill composed of quartz-biotite-sulphide cement.To view an enhanced version of this graphic, please visit:https://images.newsfilecorp.com/files/10074/275866_34fbc694940758d3_005full.jpgFigure 4: Rock sample (2025PK0003) from the Friday Creek Zone showing moderate k-feldspar and biotite alteration with blebby bornite and chalcopyrite mineralization.To view an enhanced version of this graphic, please visit:https://images.newsfilecorp.com/files/10074/275866_canadaone_figure4.pngThe company intends to undertake a comprehensive interpretation of the initial field observations, integrating lithological, alteration, and mineralization data to refine the current geological setting. A follow-up field program is scheduled to commence in Q2 2026, with objectives focused on delineating alteration zonation patterns, sulphide mineral distribution, and the structural controls on mineralization. Detailed petrographic and geochemical analyses will be employed to better constrain the relationship between the observed hydrothermal alteration assemblages and the inferred porphyry center at the Copper Dome Project. These efforts are expected to enhance the company's understanding of the system's geometry and vectoring potential, thereby guiding future drilling and exploration targeting.All rock samples collected from the fall 2025 fieldwork program are pending and were submitted to ALS Geochemistry - Kamloops to be analysed for gold and platinum group elements (50 g fire assay), and multi-element geochemistry, including elements Cu, Pb, Zn, Co, and Ag (method ME-MS61).About The Copper Dome ProjectCopper Dome is located in the lower Quesnel Trough porphyry belt, one of British Columbia's most prolific mining districts.

Vancouver, British Columbia--(Newsfile Corp. - November 5, 2025) - Canada One Mining Corp. (TSXV: CONE) (OTC Pink: COMCF) (FSE: AU31) ("Canada One" or the "Company") is pleased to provide an exploration review of the Boundary Zone at its 100% owned Copper Dome Project, ("Copper Dome", "Project" or "Property"), Princeton B.C.BOUNDARY ZONE HISTORICAL HIGHLIGHTS Extensive Copper-gold Zone Defined mobile metal Ion (MMI) sampling has delineated a strong, north-northeasterly striking Cu-Au anomalous corridormeasuring approximately 1,000 m wide and 1,750 m longopen to both the north-northeast toward the Copper Mountain Mine deposits (1.5 km away) and the south-southwestHigh-Grade Copper in Soils and Rocksnumerous MMI copper values exceed 10,000 ppb rock sampling within the zone assayed 1.06 % Cu, 0.17 g/t Au, and 0.46 g/t Pd1Zinc-Lead-Cadmium Depletion MMI sampling in the zone returned depleted Zn-Pb-Cd, consistent with the core of a Cu porphyry systemPotassic AlterationMMI sampling returned elevated potassium values indicating potassic alteration, a diagnostic feature of Cu porphyry systemsPeter Berdusco, President and CEO of the Company commented: "The Boundary Zone historical results outline a broad copper-gold system extending toward Copper Mountain. Copper values above 10,000 ppb and evidence of potassic alteration are consistent with porphyry-style mineralization. These findings make the Boundary Zone a clear focus for detailed geochemical and geophysical follow-up head of future drill targeting."Boundary Review The main feature of this area is a very dominant copper-gold anomalous zone that also contains silver and molybdenum anomalies. It strikes north northeasterly, has an approximate width of 1,000 meters, and has a minimum strike length of 1,750 meters being open to the north-northeast towards one of the Copper Mountain Mine pits which are only 1,500 meters away. It is also open to the south-southwest. The copper results are especially high with many of the values above 10,000 ppb. Two rock samples taken within this anomaly contain copper mineralization with one of these samples also containing gold. In addition, at the southwest edge of the anomaly where it is open to the southwest two rock samples taken also containing copper mineralization with gold. The copper-gold anomalous zone is also somewhat devoid of anomalous values in zinc, lead, and cadmium. Most of the anomalous values in these elements occur outside of the main zone, especially to the east. Certain types of porphyry copper deposits are known to contain zinc mineralization around their peripheries. Another feature is the potassium values which are higher within the anomalous zone. This indicates potassic alteration, often associated with porphyry copper deposits. Niobium, titanium, yttrium, and zirconium values were also plotted since these four elements indicate Lost Horse intrusive which on the Copper Mountain mine site, either hosts and/or is adjacent to copper mineralization. In general, these elements are somewhat lower within the anomalous zone, but higher outside, especially to the east. This indicates the possibility that the Lost Horse intrusive may occur to the immediate east of the anomalous zone.1Figure 1: Location Map of the Copper Dome ProjectTo view an enhanced version of this graphic, please visit:https://images.newsfilecorp.com/files/10074/273276_43de5a2644d74a75_002full.jpgFigure 2: Grid Map of Boundary Zone MMI Sampling - Copper ResultsTo view an enhanced version of this graphic, please visit:https://images.newsfilecorp.com/files/10074/273276_43de5a2644d74a75_003full.jpgFigure 3: Grid Map of Boundary Zone MMI Sampling - Gold ResultsTo view an enhanced version of this graphic, please visit:https://images.newsfilecorp.com/files/10074/273276_43de5a2644d74a75_004full.jpgFigure 4: Grid Map of Boundary Zone MMI Sampling - Silver ResultsTo view an enhanced version of this graphic, please visit:https://images.newsfilecorp.com/files/10074/273276_43de5a2644d74a75_005full.jpgFigure 5: Grid Map of Boundary Zone MMI Sampling - Potassium ResultsTo view an enhanced version of this graphic, please visit:https://images.newsfilecorp.com/files/10074/273276_43de5a2644d74a75_006full.jpgManagement cautions that past results, discoveries and mineralization on Copper Mountain are not necessarily indicative of the results that may be achieved on Copper Dome.About The Copper Dome ProjectCopper Dome is located in the lower Quesnel Trough porphyry belt, one of British Columbia's most prolific mining districts.

Vancouver, British Columbia--(Newsfile Corp. - October 22, 2025) - Canada One Mining Corp. (TSXV: CONE) (OTC Pink: COMCF) (FSE: AU31) ("Canada One" or the "Company") is pleased to provide an exploration review of the Combination Creek Zone at its 100% owned Copper Dome Project, ("Copper Dome", "Project" or "Property"), Princeton B.C. COMBINATION CREEK ZONE HIGHLIGHTS Location: ~3.5 km south of the Copper Mountain Mine depositsHistorical Drilling: 5,732m of diamond drilling in 22 holes2Dill Hole PT-12-26: 20.00m of 0.64% Cu, including 14.00m of 0.86%, starting at 141.00m and 145.00m, respectively.Drill Hole PT-11-18: 102.25m of 0.11% Cu, including 6.00m of 0.25%, starting at 3.28m and 74.00m, respectively.Drill Hole PT-10-06: 19.50m of 0.34% Cu, including 4.50m of 0.36% Cu%, starting at 106.50m and 121.50m, respectively.Drill Hole PT-11-21: 69.00m of 0.21% Cu, including 12.00m of 0.49% Cu, starting at 18.00m and 99.00m, respectively.Historical Grab Samples: returning up to 1.97% Cu and 10.7 g/t Ag1Historical Chip Samples: averaging 0.563% Cu and 3.6 g/t Ag over 5 m1Excellent Camp Setting: Intrusive-volcanic contacts beside an operating minePeter 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, and 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 ResultsDrilling 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-10-01: 20.00m of 0.28% Cu, including 5m of 0.59% Cu, starting at 27.50m.DDH PT-10-02: 47.50m of 0.19% Cu, including 22.50m of 0.26% Cu, starting at 37.00mDDH 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 ZoneMarquis of LorneThe 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 intrusions-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 FractionThe 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 sulphide-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.1The 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 Mountain stock, suggesting potential for porphyry-style copper-gold mineralization.1Figure 1: Location Map of the Copper Dome ProjectTo view an enhanced version of this graphic, please visit:https://images.newsfilecorp.com/files/10074/271468_7db7363c94780a0e_002full.jpgFigure 2: Map of Combination Creek Zone with Selected Historical Drill Hole Locations and Results (Cu)To view an enhanced version of this graphic, please visit:https://images.newsfilecorp.com/files/10074/271468_7db7363c94780a0e_003full.jpgAbout The Copper Dome ProjectCopper 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 CompletedGeophysics: 51 km of induced polarization (IP); airborne magnetic and electromagnetic (EM) coverage over ~50% of the PropertySampling: 2,253 soils and 378 rocks collectedDrilling: 8,900+ m of diamond drillingTrenching: Over 1 km excavatedWith a five-year drill permit in place, the Company is focused on advancing the Project toward drill-ready target definition.About Canada OneCanada One Mining Corp. is a Canadian junior exploration company focused on copper-the critical metal powering the global energy transition.

Vancouver, British Columbia--(Newsfile Corp. - October 7, 2025) - Canada One Mining Corp. (TSXV: CONE) (OTC Pink: COMCF) (FSE: AU31) ("Canada One" or the "Company") announces it has agreed to acquire a 4,836-hectare copper-gold property contiguous to the northwest of Hudbay Minerals' Copper Mountain Mine, to be known as "Copper Dome North" (the "Property").Under the property purchase agreement, dated October 6, 2025, (the "Agreement"), the Company will acquire a 100% interest in the Property, from an arm's-length vendor (the "Acquisition"). The Acquisition increases the Company's flagship Copper Dome Project ("Copper Dome") size by ~60%, to 12,833 ha (from 7,997 ha) (see Figure 1: Copper Dome Project Map with Newly Acquired Copper Dome North). Peter Berdusco, President and CEO, commented: "Though outside the formal Copper Dome footprint, the Property's proximity to Copper Mountain and its continuity within the district's geologic setting warrant the designation 'Copper Dome North.' In addition, the Property is adjacent to our 100%-owned Goldrop, an under-explored, historical small-scale producer of high-grade gold and silver. Together, these factors make the Acquisition compelling and well suited to a systematic exploration program." Copper Dome North Acquisition TermsThe Agreement provides for the 100% acquisition of the Property with no net smelter return royalty (NSR) in consideration for 250,000 common shares of the Company (the "Consideration Shares"), valuing the transaction at $12,500 based on a deemed price of $0.05 per share. The Consideration Shares will be subject to a statutory hold period of four months and one day from the closing of the Acquisition.Completion of the Acquisition is subject to customary closing conditions and acceptance by the TSX Venture Exchange. The Acquisition does not involve any Non-Arm's Length Parties (as defined in Exchange policies). The Company will not devote the majority of its working capital or resources to the development of Copper Dome North. The primary focus of the Company remains the exploration and future drilling at Copper Dome. As a result, the Acquisition does not constitute a "fundamental acquisition" for the Company within the policies of the Exchange. No finders' fees or commissions are payable in connection with the Acquisition.Figure 1: Copper Dome Project Map with Newly Acquired Copper Dome NorthTo view an enhanced version of this graphic, please visit:https://images.newsfilecorp.com/files/10074/269454_8dfa2c44344ed82c_001full.jpgAbout Copper DomeCopper Dome is located in the lower Quesnel Trough porphyry belt, one of British Columbia's most prolific mining districts.
