Edmonton, September 20, 2024 – Altiplano Metals Inc. (TSXV:APN) (WKN: A2JNFG)) ("Altiplano" or the "Company") further to the Company’s press release dated September 6th, 2024, the Company continues to work towards the filing of its annual audited financial statements and MD&A for the 15 months ended March 31, 2024 (the “Required Filings”).  As a result of further delays in the completion of the audit, the Company received the approval of the Alberta Securities Commission to extend the Management Cease Trade Order (“MCTO”) under National Policy 12-203 Cease Trade Orders (“NP 12-203”) to October 1st, 2024. The Company has provided all information requested by the auditor, and the auditor is currently undertaking its final review process of the Required Filings.  The Company also expects to file its interim financial statements for the quarter ended June 30, 2024 shortly after the Required Filings are completed and filed.

The Required Filings were due to be filed by July 29, 2024.  In connection with the previously disclosed delays in making the Required Filings, the Company made an application for an MCTO under NP 12-203 to the Alberta Securities Commission, as principal regulator for the Company, and the MCTO was issued on July 31, 2024.  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.

Neither the TSX Venture Exchange nor its Regulation Services Provider (as that term is defined in the policies of the (TSX Venture Exchange) accepts responsibility for the adequacy or accuracy of this release.

This release includes certain statements that may be deemed "forward-looking statements". All statements in this release, other than statements of historical facts, that address exploration drilling, exploitation activities and events or developments that the Company expects are forward-looking statements. A qualified person has not done sufficient work to classify any historical estimates as current mineral resources or mineral reserves and the issuer is not treating the historical estimates as current mineral resources or mineral reserves. The Farellon mine was previously in production dating back to the 1970’s with a reported historical production (to a depth of 70 m) yielding approximately 300,000 tonnes at an average grade of 2.5% copper and 0.5g/t gold. This material was processed locally and sold to ENAMI. Altiplano is relying upon past production records, underground sampling and related activities and current diamond drilling to estimate grade and widths of the mineralization to reactivate production. The decision to commence production on the Farellon deposit is not based on a feasibility study of mineral reserves demonstrating economic and technical viability and there is increased uncertainty and economic and technical risks of failure associated with any production decision. Although the Company believes the expectations expressed in such forward-looking statements are based on reasonable assumptions, such statements are not guarantees of future performance and actual results or developments may differ materially from those in the forward-looking statements. Factors that could cause actual results to differ materially from those in forward-looking statements include market prices, exploitation and exploration successes, continuity of mineralization, uncertainties related to the ability to obtain necessary permits, licenses and title and delays due to third party opposition, changes in government policies regarding mining and natural resource exploration and exploitation, and continued availability of capital and financing, and general economic, market or business conditions. Investors are cautioned that any such statements are not guarantees of future performance and actual results or developments may differ materially from those projected in the forward-looking statements.
