Altiplano Defines Prospective 3.5 x 1.5 km Epithermal Alteration System at Pastillas

Altiplano Metals Inc. (TSXV: APN) (WKN: A2JNFG) ("Altiplano" or the "Company") is pleased to provide an update on ongoing surface reconnaissance work that has identified a large 3.5 x 1.5 km alteration corridor (Figure 1) at the Pastillas Gold-Copper project (the "Property"), located within the prolific Maricunga Gold Belt in northern Chile's Atacama region (Figure 2).

Geological Mapping

The Company recently completed a reconnaissance bedrock mapping program covering prospective exposed alteration within the southern portion of the Property to contextualize historical data and develop a model for future drill target generation (Figure 3). The mapping area was chosen to evaluate potential alteration identified in historical ASTER data and in limited historical sampling. The mapping campaign was completed over approximately six square kilometres, and identified a corridor of alteration striking roughly north-south and measuring approximately 3.5 x 1.5 kilometres. Argillic to advanced argillic alteration and steam-heated zones observed are consistent with the Company's interpretation that Pastillas is likely a high-level exposure of an epithermal system, and may be related to alteration along-trend at Rio2's Fenix deposit and Yamana's La Pepa deposit (Figure 4).

Prospecting and Sampling

Concurrent with the bedrock mapping program, 33 outcrop samples were collected to contextualize the alteration observed in mapping and serve as additional vector information for future mineralization targeting. The collected samples will be analyzed for important pathfinder elements, and short-wave infrared (SWIR) spectroscopy will also be completed to determine the alteration mineral assemblages present in the samples. The Company also initiated the collection of a high-resolution talus fines sampling grid to be analyzed via SWIR spectroscopy to provide a comprehensive map of alteration mineralogy covering prospective areas within the southern portion of the Property. Alteration minerals are indicative of specific pH and temperature conditions present at the time of mineral formation, and serve as important markers for conditions necessary for ore formation in epithermal and porphyry mineralization environments. When the talus fines sampling grid is completed and analyzed, this dataset will provide a robust indication of alteration intensity and vertical and lateral proximity to potential mineralization centres below the exposed lithocap.

Alastair McIntyre, President and CEO comments, "We are very pleased to have delineated a multi-kilometre scale alteration footprint in initial reconnaissance mapping that confirmed and significantly expanded on zones of known alteration from limited historical work. Initial indications that Pastillas may be situated in the upper portions of a large epithermal system appear to be validated with this recent work, and we look forward to sharing the results of outcrop multi-element geochemistry and talus fines SWIR analysis as they become available."
