ALTIPLANO UPDATES STATUS ON LATE FILING OF FINANCIAL STATEMENTS

Altiplano Metals Inc., further to its news release dated July 21, 2026, continues to work toward the filing of its annual financial statements for the year ended March 31, 2026, the management's discussion and analysis, and the related chief executive officer and chief financial officer certifications.

The company advises that the audit process has now commenced. During the past week, the auditor completed the necessary preliminary administrative and planning procedures, and has begun its audit work using the financial information provided by the company. The audit remains in its early stages and the company continues to work closely with its auditor to advance the audit as efficiently as possible. The company will provide further updates as material progress is made.

The company remains committed to completing the audit and making the required filings as expeditiously as possible and, in any event, no later than Sept. 28, 2026. The company expects to file its interim first quarter financial statements within one week thereafter.

The required filings were due to be filed by July 29, 2026. 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, to the Alberta Securities Commission, as principal regulator for the company, and the MCTO was issued on July 31, 2026. 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. MCTO will remain in effect 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 biweekly 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.
