ALTIPLANO METALS ANNOUNCES CHANGE IN FINANCIAL YEAR END

Altiplano Metals Inc. is changing its financial year-end to March 31 from its current year-end of Dec. 31.

As a result, the corporation will file an additional interim report as of Dec. 31, 2023, and will report audited financial results for a 15-month transition year from Jan. 31, 2023, to March 31, 2024 (with a comparative of the 12 months ended Dec. 31, 2022). Afterward, 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 those of its peer group in the mineral resource 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.
