COPPER ONE RESOURCES SIGNS DEFINITIVE AGREEMENT TO ACQUIRE UTAH COPPER PROJECT, EXPANDS NORTH AMERICAN PORTFOLIO AND UPDATES SPECIAL WARRANTS

Copper One Resources Corp. has entered into a share exchange agreement among the company, Rooinek Mining Corp., a Nevada company, and the shareholders of Rooinek, pursuant to which the company will acquire 100 per cent of the issued and outstanding shares of common stock in the capital of Rooinek.

The acquisition adds a second U.S. copper exploration project to Copper One's growing portfolio, complementing its flagship Majuba Hill copper-silver-gold project in Nevada. The company also announces an update to the pricing terms of its previously announced non-brokered special warrant offering, as further described below.

About Rooinek

Rooinek controls the Sport project, comprising 108 contiguous unpatented lode mining claims covering approximately 1,902 acres (770 hectares) within the historic San Francisco (Frisco) mining district, on lands administered by the U.S. Bureau of Land Management (BLM) in Beaver county, western Utah.

The Sport project is located on trend with the Cactus copper-gold project, currently being explored by Hawk Resources, formerly Alderan Resources, within the San Francisco mining district. Historic mining throughout the district indicates its prospectivity for breccia and intrusive-related copper-gold-silver mineralization. The breccias are interpreted to be associated with a concealed copper-mineralized intrusive system.

Surface mapping has identified extensive magmatic-hydrothermal breccias, alteration and structural features that support the interpretation that the near-surface, breccia-hosted mineralization may be associated with a large intrusive-related copper system. Modern exploration techniques could significantly enhance understanding of the property's mineral potential.

Copper One believes that the favourable geology of the project area, together with the historic mining within the district, suggests that the Sport project has significant discovery potential.

The property benefits from excellent infrastructure, year-round access and favourable topography. Current exploration activities include compilation of historical data, remote sensing, geological mapping and multielement geochemical sampling designed to refine priority drill targets.

Utah is widely recognized as one of North America's premier mining jurisdictions, supported by established infrastructure, a skilled work force and a long history of responsible mineral development.

David Greenway, president and chief executive officer of Copper One, commented: "The acquisition of Rooinek represents another important step in Copper One's strategy of assembling a portfolio of high-quality copper exploration assets in premier North American mining jurisdictions. The Sport project exhibits many of the geological characteristics we seek, including evidence of a potentially significant intrusive-related copper system, excellent infrastructure and year-round exploration access. We believe this acquisition complements our flagship Majuba Hill project while providing shareholders with exposure to another compelling copper discovery opportunity in the United States. As we continue advancing Majuba Hill, Rooinek adds another exciting growth platform for generating long-term shareholder value."

Transaction terms

Pursuant to the terms of the definitive agreement, as consideration for the acquisition of 100 per cent of the issued and outstanding shares of common stock in the capital of Rooinek, the company will issue an aggregate of 14 million common shares in the capital of the company pro rata to the shareholders at a deemed price of 55 cents per consideration share.

All consideration shares to be issued to the shareholders shall be subject to a voluntary escrow, whereby the consideration shares will remain subject to contractual resale restrictions, to be released on the date that is four months and one day following the closing date.

3. The representations and warranties of each party contained in the definitive agreement being true and correct in all material respects as of the closing date;
4. Each party having performed and complied with its respective covenants and obligations under the definitive agreement;

Update to previously announced special warrant offering

Further to the company's news release dated July 6, 2026, announcing a non-brokered private placement of up to 19.5 million special warrants of the company at a price of 50 cents per special warrant for aggregate gross proceeds of up to $9.75-million, the company announces that it has amended the pricing terms of the offering. The subscription price per special warrant has been reduced from 50 cents to 44 cents, resulting in revised aggregate gross proceeds of up to $8.58-million (reduced from $9.75-million). The number of special warrants issuable under the offering remains unchanged at up to 19.5 million.

In connection with the repricing, the exercise price of the share purchase warrants underlying each unit issuable upon conversion of the special warrants has been amended from 62 cents to 55 cents per common share. All other terms of the offering, including the conversion terms of the special warrants, the composition of the units, the warrant term, the acceleration provisions, the 10-per-cent blocker provision and the intended use of proceeds, remain unchanged from those described in the company's news release dated July 6, 2026.

The company may pay finders' fees on the offering within the amount permitted by the policies of the CSE.

The special warrants are expected to be issued pursuant to exemptions from the prospectus requirements under Canadian securities laws, including the accredited investor, $150,000 minimum investment or other relevant exemptions under National Instrument 45-106, Prospectus Exemptions. Prior to the filing of a prospectus supplement and the automatic conversion of the special warrants, the securities issued under the offering will be subject to a four-month hold period from the date of closing of the offering in addition to any other restrictions under applicable law.

About Copper One Resources Corp.

Copper One Resources 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 (artificial intelligence) infrastructure and data centres, 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, Nev. Majuba Hill is an exploration-stage porphyry copper project situated in a premier mining jurisdiction with excellent infrastructure, where continuing exploration is focused on evaluating the scale and continuity of a large copper-silver-gold mineralized system.

Copper One also owns a 100-per-cent 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-per-cent interest in the Redhill property, located south of Ashcroft, B.C., 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.

Subject to completion of the proposed transaction, Copper One will hold four highly prospective copper-focused exploration projects across Nevada, Utah and British Columbia, significantly expanding its North American critical metals portfolio.

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.

We seek Safe Harbor.
