COPPEREX ANNOUNCES EFFECTIVE DATE OF SHARE CONSOLIDATION

September 15, 2026 TSXV: CUEX

Vancouver, British Columbia COPPEREX RESOURCES CORP. (CUEX) (the "Company") is pleased to announce that, further to its news release dated August 24, 2026 announcing a consolidation (the "Consolidation") of all the Company's outstanding common shares on the basis of ten (10) pre- Consolidation common shares for one (1) post-Consolidation common share, the Consolidation will be effective and the Company's common shares will commence trading on a consolidated basis effective at the market opening on September 18, 2026 (the "Effective Date"). The new CUSIP for the Company's consolidated common shares is 217641208. The Company's name and stock symbol will not change in connection with the Consolidation and the post-Consolidation common shares will continue to be listed on the TSX Venture Exchange under the stock symbol "CUEX". The reason for the Consolidation is to increase the Company's flexibility in the marketplace.

The Company currently has 31,833,014 common shares issued and outstanding. As at the Effective Date, the Company will have approximately 3,183,301 common shares issued and outstanding. Any fractional common share of the Company remaining after the Consolidation that is less than one-half of a common share will be cancelled and any fractional common share of the Company that is at least one-half of a common share will be rounded up to the nearest whole common share.

Registered shareholders holding their common shares in certificated form or whose common shares are represented by a direct registration advice ("DRS") statement will receive a letter of transmittal from Odyssey Trust Company, the Company's transfer agent, in respect of the Consolidation. The letter of transmittal will contain instructions to such registered shareholders on how to surrender the share certificates representing their pre-Consolidation common shares and authorize Odyssey to issue a DRS statement representing their post-Consolidation common shares. Share certificates evidencing ownership of post-Consolidation common shares will not be issued unless specifically requested. Non- registered shareholders holding common shares of the Company through an intermediary (a securities broker, dealer, bank or financial institution) should be aware that the intermediary may have different procedures for processing the Consolidation than those that will be put in place by the Company for registered shareholders. If shareholders hold their common shares of the Company through intermediaries and have questions in this regard, they are encouraged to contact their intermediaries.

On behalf of the Board of Directors
