COPPEREX ADOPTS SEMI-ANNUAL FINANCIAL REPORTING

May 26, 2026 TSX.V: CUEX

Vancouver, British Columbia COPPEREX RESOURCES CORP. (CUEX) (the "Company") announces that it has adopted semi-annual financial reporting ("SAR") pursuant to the British Columbia Securities Commission Coordinated Blanket Order 51-933 Exemptions to Permit Semi-Annual Reporting for Certain Venture Issuers (the "Blanket Order").

The Blanket Order allows eligible venture issuers to voluntarily move from a quarterly to a semi-annual financial reporting framework. The Company has determined that it meets the eligibility criteria under the Blanket Order, including that it is a venture issuer, has annual revenue of less than $10 million, has a disclosure record of over 12 months and has filed all required periodic and timely disclosure documents.

The Company's fiscal year ends on December 31. Under the provisions of the Blanket Order, the Company will be exempt from the requirements to file interim financial statements and associated management's discussion and analysis ("MD&A") for its three-month (Q1) and nine-month (Q3) interim periods. The initial interim period for which the Company will not file is the three-month (Q1) period ended March 31, 2026. The Company will continue to file audited annual financial statements and MD&A (due within 120 days of December 31) and unaudited six-month (Q2) financial statements and MD&A (due within 60 days of June 30).

This news release is being filed pursuant to the Blanket Order 51-933 Exemptions to Permit Semi-Annual Reporting for Certain Venture Issuers. The Company remains fully committed to transparency and timely disclosure and will continue to promptly disclose all material changes and significant developments through news releases and material change reports, ensuring that investors remain informed between reporting periods as required under National Instrument 51-102 Continuous Disclosure Obligations and the policies of the TSXV. By adopting SAR, the Company aims to reduce the administrative and financial burden associated with quarterly reporting.
