COPPER ONE RESOURCES CORP. ANNOUNCES CHANGE OF STOCK TRADING SYMBOL TO "CEXY" ON THE CANADIAN SECURITIES EXCHANGE AND AMENDED TERMS OF NON-BROKERED LISTED ISSUER FINANCING EXEMPTION OFFERING

Effective May 19, 2026, Copper One Resources Corp.'s stock trading symbol on the Canadian Securities Exchange will change from BFG to CEXY. The symbol change is being undertaken to align the company's ticker symbol with its current name, Copper One Resources Corp. The company's OTC symbol (BFGFF) and Frankfurt Stock Exchange symbol (YW5) remain unchanged.

The company recently completed a change of its corporate name from Giant Mining Corp. to Copper One Resources Corp. The symbol change reflects this transition and is intended to ensure that the company's trading symbol is consistent with its new corporate identity.

The company believes the symbol change will enhance its visibility and better align with its new corporate identity and strategic focus in the copper sector, supporting broader market recognition among investors and stakeholders interested in critical minerals for electrification and energy transition initiatives.

The company also announces that it has amended the terms of its previously announced non-brokered private placement offering pursuant to the listed issuer financing exemption under Part 5A.2 of National Instrument 45-106 (Prospectus Exemptions), originally announced on May 12, 2026. The price per non-flow-through unit and per flow-through unit has been revised from 43 cents to 40 cents. The LIFE offering will consist of up to 2.5 million NFT units at a price of 40 cents per NFT unit for gross proceeds of up to $1-million and up to 3.75 million FT units at a price of 40 cents per FT unit for gross proceeds of up to $1.5-million for aggregate amended gross proceeds of up to $2.5-million.

All other terms of the NFT units, FT units and warrants remain unchanged from the terms previously announced on May 12, 2026. The LIFE offering is expected to close on or around May 30, 2026, as previously announced. For full details regarding the terms of the LIFE offering, including the composition of the NFT units and FT units, use of proceeds, offering jurisdictions, hold periods, and finders' fees, prospective investors should refer to the company's news release dated May 12, 2026. An amended and restated offering document required under the listed issuer financing exemption will be filed under the company's profile on SEDAR+ and on the company's website in connection with the revised terms of the LIFE offering. Prospective investors should read the amended offering document before making an investment decision.
