COPPER ONE RESOURCES CORP. ANNOUNCES OTC SYMBOL CHANGE TO CEXYFF FOLLOWING NAME CHANGE

Effective at the opening of market trading today, May 28, 2026, Copper One Resources Corp.'s OTC Markets trading symbol has changed from BFGFD to CEXYFF.

The OTC symbol change accompanies the company's previously announced corporate name change to Copper One Resources and reflects the company's continued transition to its new corporate identity and strategic focus on copper exploration and development.

David Greenway, chief executive officer of Copper One, commented: "The transition to the CEXYFF OTC symbol marks another important step in Copper One's evolution as a North American copper-focused exploration company. We believe copper will play a critical role in supporting electrification, AI data centre growth, renewable energy systems, grid modernization and large-scale infrastructure spending across the United State. Our goal is to position Copper One to capitalize on these long-term macro trends through the advancement of high-potential copper assets in mining-friendly jurisdictions."

The company's common shares continue to trade on the Canadian Securities Exchange (the CSE) under the symbol CEXY, on the Frankfurt Stock Exchange under the symbol IW8 and under the German WKN No. A42AGR. No action is required by existing shareholders with respect to the OTC symbol change.

Copper One believes the updated OTC trading symbol further aligns the company's market presence with its long-term strategy of advancing copper-focused exploration assets in North America amid increasing global demand for critical metals supporting electrification, artificial intelligence infrastructure, renewable energy systems and grid modernization.
