GIANT MINING ANNOUNCES EFFECTIVE DATE OF PREVIOUSLY ANNOUNCED NAME CHANGE TO COPPER ONE RESOURCES CORP. AND CONSOLIDATION

Effective April 29, 2026, Giant Mining Corp.'s name will change from Giant Mining Corp. to Copper One Resources Corp., and the company will consolidate its common shares on a one-to-10 basis as previously announced on April 22, 2026.

It is expected that the company will begin trading on the Canadian Securities Exchange (the CSE) under the new name and on a consolidated basis on April 29, 2026. The new Cusip number will be 21751T103 and the new ISIN will be CA21751T1030 for the postconsolidation common shares of Copper One Resources. The total issued and outstanding number of common shares postconsolidation will be approximately 23,718,947. The company's stock symbol will remain unchanged.

The company believes the name change and strategic repositioning will enhance its visibility within the copper sector and better align with broader market interest in critical minerals supporting electrification and energy transition initiatives.

Registered holders of physical share certificates will receive a letter of transmittal by mail advising that the name change and consolidation has been effected and will contain instructions on how to exchange share certificates evidencing preconsolidated common shares for new share certificates representing the number of postconsolidated common shares to which they are entitled. No action is required for shares held by non-registered holders (shareholders who hold their shares through an intermediary) and outstanding direct registration system.
