Altiplano Confirms Santa Beatriz Mine Exhibits IOCG Mineralization Comparable to the Farellon Copper-Gold Mine

Altiplano Metals Inc. (TSXV: APN) (WKN: A2JNFG) ("Altiplano" or the "Company") is pleased to report it has initiated technical due diligence on the Santa Beatriz Copper-Gold mine and confirms similarities to the Farellon mine in mineralization, lithology, and structural trends. The Santa Beatriz Mine is located only 2 kilometres (km) by road from the existing operation at the Farellon Copper-Gold Mine near La Serena, Chile. Farellon and Santa Beatriz are situated in the northnortheast trending 1,000-kilometre Atacama Fault zone within Chile's copper-rich iron oxide copper-gold (IOCG) belt; this area is associated with several significant deposits. Farellon and Santa Beatriz have the potential to be part of a larger IOCG system.

Highlights

• Mineralized material at Santa Beatriz offers ideal potential for processing at the Company's El Peñón facility located ~18 kilometres to the north.
• IOCG-type veins at Farellon and Santa Beatriz share similar mineral characteristics and exhibit a consistent northeast orientation, indicating the possibility that both projects could be part of a larger system.
• Copper and gold mineralization within the vein structures at both Farellon and Santa Beatriz host excellent potential to develop a high-grade copper and iron resource with associated gold.
• The Santa Beatriz Mine is permitted for ~ 2,000 tons per month of production by the Chilean mining authority SERNAGEOMIN (Servico Nacional de Geologia y Mineria), with the potential to expand to 5,000 tonnes per month.
• Seven additional mapped IOCG veins on the Santa Beatriz property remain untested.
• The previously mined veins at Santa Beatriz remain open with the potential to intersect at depth.

President and CEO Alastair McIntyre's comments: "Altiplano is very encouraged by the initial work at Santa Beatriz confirming that the geological setting is similar to Farellon. We are currently designing a program to further delineate and expand the mineralization to assist with mine planning. As the Cu-Au-Fe mineralization is similar to the Farellon Mine, it is ideally suited for processing at our El Peñón facility. Santa Beatriz aligns with APN's focus on maintaining low transport, processing, and production costs while optimizing the recovery of the contained metals."

Estimation of quantity and grade is conceptual in nature with insufficient work completed to define a mineral resource. A decision to conduct exploration or development at the Santa Beatriz site is not based on a feasibility study of mineral reserves demonstrating positive economic and technical viability therefore resulting in increased uncertainty and risk. Further exploration may or may not define a resource at Santa Beatriz or determine positive mining economics.

Geology

The Farellon and Santa Beatriz properties are similar in lithology, structural setting, and mineralization styles. The Santa Beatriz property contains multiple steeply dipping, northeast-trending IOCG-type veins hosted in microdiorite and andesite. The two primary, historically mined veins, located in the southeast section of the property, are up to 1.5 meters wide and remain open along strike and at depth. Similar structures in the region widen at depth, indicating the potential for expanded downdip continuity of mineralization.

Seven smaller untested veins mapped at the Santa Beatriz project are up to 50 centimeters wide. Mineralization in veins includes chalcopyrite, bornite, and magnetite with abundant copper oxides (malachite and chrysocolla).

Exploration Plan

After reviewing and evaluating the existing datasets for Santa Beatriz, an initial exploration program has been formulated encompassing activities such as mapping, sampling, and drilling. The Exploration program is scheduled to commence in July 2023. Channel sampling and mapping of the veins underground and on the surface will aid in determining grade potential and extent. A 1,300-meter drill program is planned to validate the width and consistency of the veins at depth to determine mineralization and mining potential. A subsequent exploration program will include a detailed ground magnetic survey to examine the potential depth and extent of the additional IOCG veins on the Santa Beatriz project; drilling of the veins would be required to validate the geophysics. The additional untested veins on the project have the potential to be included in the production of the Santa Beatriz project.
