Altiplano Signs Option Agreement to Acquire Santa Beatriz Cu-Au Mine

Edmonton, June 14, 2023 - Altiplano Metals Inc. (TSXV: APN) (WKN: A2JNFG) ("Altiplano" or the "Company") is pleased to report it has entered into an agreement for the acquisition of the Santa Beatriz Mine, located two kilometers (km) from the Company's existing operation at the Farellon Copper Gold Mine site near La Serena, Chile. Copper, gold, and iron mineralized material at the Santa Beatriz Mine is similar to what is currently extracted at Farellon and is expected to be suitable material for processing at the Company's mill and processing facility, El Peñón, located ~15 km from the mine.

Highlights

• Low-cost potential acquisition of past producer covering an area of 54 ha.
• Previous workings include two decline advances totaling 250 m and 180 m in length.
• The Santa Beatriz Mine is permitted by the Chilean Mining Authority, SERNAGEOMIN (Servicio Nacional de Geologia y Mineria) for ~ 2,000 tonnes per month (tpm) of production and can be expanded.
• Mineralized material at Santa Beatriz is of the same iron-oxide-copper-gold (IOCG) deposit type and style as that at Farellon.
• Copper, gold, and iron extracted from the Santa Beatriz Mine can be ideally suited for processing at the Company's El Peñón processing facility, entering startup phase in July.
• Material produced from the Santa Beatriz Mine has the potential to improve efficiencies and increase overall production at the Mill, maximizing the Company's monthly revenue opportunities.

President and CEO, Alastair McIntyre, commented: "We are very excited for the opportunity to begin work on the Santa Beatriz Mine. This project fits Altiplano's vision for consolidating projects located in proximity to our existing operations, with low start-up costs hosting excellent material for optimal production and processing. Acquiring an additional mine with ideal production material for Altiplano's mill and processing facility creates added flexibility and sustainability while providing the potential to add significant value for its shareholders."

Santa Beatriz Agreement

In exchange for US$5,000, Altiplano retains a 3-month exclusivity period to complete due diligence on the Santa Beatriz Mine. At the end of this period, Altiplano can rent the mine for US$4,350/month and provide the owner with a 15% share in net profits after expenses. During the first 12 months of the option, APN can purchase the mine with no underlying royalty for a one-time cash payment of US$440,000 or extend the option.

The due diligence phase will include a comprehensive analysis of the veins to determine grade, width and consistency at depth, regional influence, and mining potential. Geologists will map and sample the vein sets underground and on surface, and compile and review existing datasets to aid in the determination of production and future exploration programs. A confirmation drill program will be designed as part of the exploration work to test the continuity of the vein structure and mineralogy along strike and at lower depths.
