EDMONTON, AB, August 8, 2025 – Altiplano Metals Inc. (TSXV: APN) (WKN: A2JNFG) (“Altiplano” or the “Company”) further to the Company’s news release dated July 24, 2025, the Company continues to work towards the filing of its annual audited financial statements for the year ended March 31, 2025. The Company has provided a set of draft financial statements to its auditor and continues to address requests by the auditor for further information.  Both the Company and its auditor continue to work diligently towards the completion and filing of the annual audited financial statements.

The Company’s audited financial statements, MD&A, and Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”) certifications relating to the audited financial statements for the year ended March 31, 2025 were due to be filed by July 29, 2025.  The delay arises from the Company’s and its auditors’ joint assessment of the time required to complete the remaining audit procedures and the auditors’ review process, as well as the delayed receipt of financial information from Altiplano’s Chilean subsidiaries.  The Company and its auditor are in the process of completing the associated audit work, and the Company will provide additional updates once it has determined the anticipated filing date of the audited financial statements and MD&A (the “Required Filings”).

In connection with the anticipated delays in making the Required Filings, the Company made an application for a Management Cease Trade Order (“MCTO”) under National Policy 12-203 Management Cease Trade Orders (“NP 12-203”) to the Alberta Securities Commission, as principal regulator for the Company, and the MCTO was issued on July 30, 2025.  The MCTO restricts all trading by the Company’s CEO and CFO in securities of the Company, whether direct or indirect.  The issuance of the MCTO will not affect the ability of persons who are not directors, officers or insiders of the Company to trade their securities.  The MCTO will remain in effect until the Required Filings are filed or until it is revoked or varied.

The Company confirms that it intends to satisfy the provisions of the alternative information guidelines described in NP 12-203 by issuing bi-weekly default status reports in the form of a news release until it meets the Required Filings requirement.  The Company has not taken any steps towards any insolvency proceeding and the Company has no material information relating to its affairs that has not been generally disclosed.
