Altiplano Metals Announces Change in Financial Year End

Edmonton, Alberta--(Newsfile Corp. - February 16, 2024) - Altiplano Metals Inc. (TSXV: APN) (WKN: A2JNFG) ("Altiplano" or the "Company") wishes to announce that it is changing its financial year-end to March 31 from its current year-end of December 31.

As a result, the Corporation will file an additional interim report as of December 31, 2023, and will report audited financial results for a 15-month transition year from January 31, 2023, to March 31, 2024 (with a comparative of the 12 months ended December 31, 2022). Afterwards, the Corporation will revert to a customary reporting calendar based on a March 31 year-end, with fiscal quarters ending on the last day of June, September and December and March each year.

The Company believes this change of financial year-end will allow it to complete its audit requirements with greater efficiency and will better align the Corporation's financial reporting periods to that of its peer group in the mineral resources sector, which will allow investors to better compare quarterly and annual financial results. The notice for the change in financial year-end required under National Instrument 51-102 - Continuous Disclosure Obligations will be filed under the Corporation's SEDAR profile at www.sedarplus.ca.

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. For more information on the Company, investors should review the Company's continuous disclosure filings that are available at www.sedarplus.ca.
