• 156-claim, approximately 3,900-hectare land package covers a historically drilled magmatic sulphide system with untested electromagnetic conductors  

Vancouver, BC – October 7, 2026 – Copper One Resources Corp. ( “Copper One” or the “Company”) (CSE: CEXY | OTCID: CEXYF | FSE: IW8 | WKN: A42AGR) is pleased to announce that it has entered into a purchase and sale agreement dated October 6, 2026 (the “Agreement” ) with 1594122 B.C. Ltd. (the “Vendor” ) to acquire a 100% interest in the Sword & Gossan Mineral Properties (the “Property” ), located in west-central Labrador, Newfoundland and Labrador.

The Property comprises ten mineral licences totalling 156 claims and approximately 3,900 hectares, located approximately 90 kilometres north of Churchill Falls on the northern side of the Smallwood Reservoir. It covers the historical Sword (Michikamau) nickel-copper-cobalt project, where previous operators completed airborne geophysics, surface sampling and initial drilling and identified a magmatic sulphide system that remains largely untested.

“The proposed acquisition of Sword & Gossan would expand Copper One’s North American critical metals portfolio with a nickel-copper-cobalt exploration opportunity in Labrador,” said David Greenway, President and CEO of Copper One. “Historical surface sampling and drilling identified mineralization, while multiple electromagnetic conductors remain untested. This historical work provides a basis for further technical evaluation as we assess the Property’s exploration potential.”

Terms of the Acquisition

Under the Agreement, the Company will pay the Vendor aggregate cash consideration of CAD $3,650,000, payable as follows:

Table 1 : Purchase Price and Payment Schedule

In addition, the Company will make two advance royalty payments of CAD $200,000 each to the Vendor, on the first and second anniversaries of the Effective Date, for a total of CAD $400,000. All consideration is payable in cash; no securities of the Company will be issued in connection with the acquisition.

The Property is subject to an existing 2% net smelter returns royalty (the “ NSR ”) in favour of the underlying owner of the Property (the “ Royalty Holder ”), which the Property will remain subject to upon completion of the Acquisition. One percent (1%) of the NSR may be purchased from the Royalty Holder for CAD $2,000,000 in cash, exercisable at any time by written notice, thereby reducing the NSR to an aggregate one percent (1%),

Completion of the acquisition is subject to customary conditions, including satisfactory completion of the Company’s due diligence, board approvals, receipt of any required third-party consents, acceptance of the Canadian Securities Exchange (the “ CSE ”), and there being no material adverse change in the status of the Property prior to closing.

The Vendor is at arm’s length to the Company. No finder’s fees are payable in connection with the transaction.

The Sword & Gossan Property

The Property consists of ten mineral licences — seven in the Sword project area and three in the Gossan project area — on NTS map sheets 13L05 and 23I08. It is approximately 90 kilometres north of the town of Churchill Falls, on the northern side of the Smallwood Reservoir in west-central Labrador.

Table 2 : Project Area Size

The Property is prospective for intrusive-hosted, ultramafic–mafic magmatic nickel-copper-cobalt sulphide mineralisation, with potential for associated gold, platinum and palladium. Host rocks are mapped as leuco-troctolite and troctolite of the Michikamau Intrusion. The Vendor has represented that the licences are in good standing; the next assessment expenditures totalling CAD $31,200 fall due between July and August 2027.

Historical Exploration

The Property covers a large, underexplored magmatic nickel-copper-cobalt sulphide system in the Michikamau Intrusion, one of the largest anorthosite-troctolite intrusive complexes in Labrador. The Property lies within the same broad geological province that hosts the Voisey’s Bay nickel-copper-cobalt mine, approximately 300 kilometres to the northeast.

Between 2005 and 2007, previous operators carried out a systematic exploration program over ground that now forms part of the Property, including an airborne electromagnetic and magnetic survey, geological mapping, prospecting and surface sampling, and an initial diamond drill program. Highlights of that historical work include:

• Multiple untested conductors. The airborne survey outlined a series of high-priority electromagnetic conductors that geophysical consultants interpreted as having intensities and geometries consistent with massive sulphide bodies. The majority of these conductors have never been drill-tested.  

• Nickel-copper-cobalt mineralisation at surface. Prospecting identified several gossanous showings, including the Gossan 115 and Sword Far North showings, where historical surface samples returned significant nickel, copper and cobalt values.  

• Mineralisation confirmed in drilling. A two-hole drill program at the Juno conductive zone intersected nickel-copper-cobalt sulphide mineralisation over a broad interval. The previous operator’s assessment report recommended deeper drilling at Juno to test for a feeder system to the mineralisation.  

• Favourable host rocks. The conductors are hosted in troctolite and leuco-troctolite, the same rock types that host Voisey’s Bay-style mineralisation and were interpreted as a possible feeder zone to the Michikamau Intrusion — the setting most favourable for magmatic sulphide accumulation.  

The Property represents an early-stage exploration opportunity with a documented history of nickel-copper-cobalt mineralisation and multiple untested geophysical targets across a 3,900-hectare land package.

Cautionary Note Regarding Historical Information

The historical exploration results referenced in this news release were reported by previous operators prior to the Company’s involvement in the Property and are derived from publicly available assessment reports and press releases. A qualified person, as defined in National Instrument 43-101, has not done sufficient work to verify the historical results, and the Company is not treating the historical information as current.

About Copper One Resources Corp.

Copper One Resources Corp. is focused on identifying, acquiring, and advancing high-potential copper, copper-silver-gold, and copper-molybdenum projects to help meet the growing global demand for critical metals required for electrification, AI infrastructure and data centers, renewable energy, defence, and the modernization of power systems.

The Company’s flagship asset is the Majuba Hill Copper-Silver-Gold District, located approximately 156 miles (251 kilometres) from Reno, Nevada. Majuba Hill is an exploration-stage porphyry copper project situated in a premier mining jurisdiction with excellent infrastructure, where ongoing exploration is focused on evaluating the scale and continuity of a large copper-silver-gold mineralized system.

Copper One also owns a 100% interest in the Redonda Copper-Molybdenum Project, located northeast of Campbell River in British Columbia’s Vancouver Mining Division. The district-scale project comprises approximately 2,746.46 hectares (6,786 acres) across nine mineral claims and hosts a porphyry-style copper-molybdenum system within the highly prospective Coast Suture Zone, a geological belt known for significant porphyry copper and skarn mineralization. The Company believes Redonda has the potential to become a significant long-term exploration asset as systematic exploration continues to evaluate the scale and continuity of the mineralized system.

In addition, Copper One holds an option to earn up to a 100% interest in the Redhill Property, located south of Ashcroft, British Columbia, adjacent to the Trans-Canada Highway. The 4,736-hectare (11,704-acre) property hosts volcanogenic massive sulphide (VMS) mineralization prospective for copper, zinc, silver and gold, while also demonstrating potential for epithermal gold mineralization.

Copper One also owns a 100% interest in the Sport Project in Utah through its wholly owned subsidiary, Rooinek Mining Corp., expanding the Company’s portfolio of North American copper exploration assets.

Copper One has entered into a purchase and sale agreement to acquire a 100% interest in the Sword & Gossan Mineral Properties, located in west-central Labrador, Newfoundland and Labrador.

Copper One is advancing its portfolio through systematic exploration, modern geological modelling, and disciplined technical evaluation. The Company remains committed to responsible exploration practices, technical transparency, and creating long-term shareholder value through disciplined exploration and the advancement of critical metals projects across North America.
