SILVERCO MINING FINALIZES NAME CHANGE

Further to the news release dated Oct. 22, 2025, Silverco Mining Ltd. (formerly Quetzal Copper Corp.) has completed its name change from Quetzal Copper Corp. to Silverco Mining Ltd.

Due to a labour dispute between the B.C. General Employees' Union and the government of British Columbia, B.C. Registries, the government body responsible for registrations of businesses, was temporarily closed. As a result, the company was unable to legally change its name at the time of completing its reverse takeover of Silverco Mining Corp., which closed on Oct. 17, 2025.

The company's common shares continue to trade on the TSX Venture Exchange under the trading symbol SICO, with 32,616,265 shares outstanding. The company anticipates its common shares will commence trading under the new name at market open on Nov. 4, 2025.

There is no change in the capitalization of the company in connection with the name change. No action is required by existing shareholders of the company with respect to the name change. Outstanding common share certificates or direct registration system notices do not need to be exchanged. The company's new Cusip number is 827924101, and its new ISIN is CA8279241019.
