Copper Lake adopts semi-annual reporting

Toronto, Ontario--(Newsfile Corp. - September 2, 2026) - Copper Lake Resources Ltd. (TSXV: CPL) (FSE: W0I) (" Copper Lake " or the " Company ") announces that it has elected to adopt the semi-annual reporting framework.

This news release is being filed pursuant to Coordinated Blanket Order 51-933 Exemptions to Permit Semi-Annual Reporting for Certain Venture Issuers (the "Blanket Order"). The initial interim period for which the Company intends to rely on the Blanket Order is the nine-month interim period ending July 31, 2026.

Accordingly, the Company will not file interim financial statements, related management's discussion and analysis or related officer certifications for the three and nine-month interim periods ended July 31, 2026. The Company's next interim financial disclosure will instead be filed for the six-month period ending April 30, 2027, in accordance with the timelines prescribed under applicable securities legislation. The Company intends to continue filing on a semi-annual basis.

The Company believes that adopting semi-annual reporting will reduce the administrative and financial burden associated with quarterly reporting and is consistent with the objective of the Blanket Order to provide reporting flexibility for venture issuers.

Notwithstanding the adoption of the semi-annual reporting framework pursuant to the Blanket Order, the Company remains subject to all applicable timely disclosure obligations and continuous disclosure requirements under securities legislation, including the requirement to disclose material changes in the affairs of the Company on a timely basis.
