(via TheNewswire)

Vancouver, BC – August 20, 2026 – TheNewswire - Copper One Resources Corp. (“Copper One” or the “Company”) (CSE:CEXY | OTCID:CEXYF | FSE:IW8 | WKN: A42AGR) announces that further to its news releases dated July 6, 2026, July 20, 2026, and August 10, 2026 (collectively, the “ Prior Releases ”), the Company has further amended the terms of its previously announced non-brokered special warrant offering (the “ Offering ”).

The Offering has been restructured from a single class of up to 19,500,000 special warrants into two classes, consisting of up to (i) 15,000,000 non-flow-through special warrants of the Company (each, a “NFT Special Warrant ”) at a purchase price of $0.40 per NFT Special Warrant, for aggregate proceeds of up to $6,000,000, and (ii) 5,000,000 flow-through special warrants of the Company (each, a “ FT Special Warrant ” and, together with the NFT Special Warrants, the “ Special Warrants ”) at a purchase price of $0.40 per FT Special Warrant, for aggregate proceeds of up to $2,000,000, for combined aggregate gross proceeds of up to $8,000,000 .

Each NFT and FT Special Warrant will automatically convert, without payment of any additional consideration, into one unit of the Company (a “Unit ”), in each case on the conversion date as described in the Prior Releases. Each FT Special Warrant will qualify as a “flow-through share” as defined in subsection 66(15) of the Income Tax Act (Canada). Each Unit will be comprised of one common share of the Company (a “ Share ”), to be issued on a non-flow-through basis, and one-half of one common share purchase warrant (each whole warrant, a “ Warrant ”).

All other terms of the Offering, including the exercise price of the Warrants ($0.50 per Warrant Share), the warrant term (two years from closing), the acceleration provisions, the ten percent blocker provision, the finder’s fee terms, and the intended use of proceeds, remain unchanged from those described in the Prior Releases.

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 the 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.

The securities issuable pursuant to the Offering have not, nor will they be registered under the United States Securities Act of 1933, as amended, and may not be offered or sold within the United States or to, or for the account or benefit of, U.S. persons in the absence of U.S. registration or an applicable exemption from the U.S. registration requirements. This news release shall not constitute an offer to sell or the solicitation of an offer to buy nor shall there be any sale of the securities in the United States or in any other jurisdiction in which such offer, solicitation or sale would be unlawful.

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 across North America. The Company’s portfolio is positioned to help meet the growing global demand for critical metals required for electrification, artificial intelligence infrastructure and data centers, renewable energy, defence applications 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) east-northeast of Reno, Nevada. Majuba Hill is an exploration-stage porphyry copper project situated in a premier mining jurisdiction with established infrastructure. Ongoing exploration is focused on evaluating the scale, grade and continuity of its 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 hectares (6,786 acres) across nine mineral claims and hosts a porphyry-style copper-molybdenum system within the prospective Coast Suture Zone, a geological belt recognized for porphyry copper and skarn mineralization. Systematic exploration is continuing 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 mineralization prospective for copper, zinc, silver and gold, as well as potential for epithermal gold mineralization.

Copper One also owns a 100% interest in the Sport Project in Beaver County, western Utah. The acquisition adds a second U.S. copper exploration project to the Company’s portfolio, complementing its flagship Majuba Hill project in Nevada. The Sport Project comprises 108 contiguous unpatented lode mining claims covering approximately 1,902 acres (770 hectares) within the historic San Francisco Mining District on lands administered by the U.S. Bureau of Land Management. The property is prospective for breccia- and intrusive-related copper-gold-silver mineralization and benefits from established infrastructure, year-round access and favorable topography. Current exploration activities include historical data compilation, remote sensing, geological mapping and multi-element geochemical sampling designed to refine priority exploration targets.

Copper One holds four copper-focused exploration projects across Nevada, Utah and British Columbia. The Company is advancing its portfolio through systematic exploration, modern geological modelling and disciplined technical evaluation while remaining committed to responsible exploration practices, technical transparency and the creation of long-term shareholder value.
