Altiplano Samples up to 6.21% Copper and 0.44g/t Gold over 1.4 Metres Underground at Rosario

Edmonton, September 1, 2020 - Altiplano Metals Inc. (TSXV: APN) (WKN: A2JNFG) ("Altiplano" or the "Company") is pleased to announce results from recent underground geological mapping and channel sampling at the historic Rosario Copper-Gold mine located 600 m southeast of the Farellon Copper-Gold vein system, near La Serena, Chile.

During July, Altiplano's technical team conducted an underground mapping and sampling program along the NE trending vein structure. Samples were taken approximately 15 m apart covering a total strike length of 181 m. Each sample was removed from a clean representative surface, blasted one meter below the floor level. The samples were cut to a depth of 8 cm with an average width of 15 cm and sampled across the length of the vein. The grades observed ranged from a low 0.08 g/tonne gold to a high of 1.04 g/tonne gold with a average of 0.37 g/tonne. Copper ranged from 0.89% to a high of 6.22% copper with a average of 2.88%.

CEO Alastair McIntyre commented, "These results at the Rosario copper-gold vein system are similar to the early results underground sampling and drill results obtained at Farellon. We are encouraged by the higher gold content which is higher at Rosario than at Farellon. The Company has commenced initial planning and engineering studies to conduct an underground bulk sample program. McIntyre further comments, "The location of the fully permitted Rosario project is ideally located within 600 m of Farellon where we can leverage the available infrastructure, resources and services. Rosario fits within our goal of adding additional productive assets and consolidating regionally."

Geology

The Rosario project hosts copper-gold mineralization found within a discrete and laterally continuous east-northeast trending vein system, predominantly hosted in a Cretaceous granodiorite. Similar to Farellon, the iron-oxide-copper-gold vein system occurs in a steeply dipping fault. The vein system is located approximately 600 m from Farellon and is accessible through historical decline workings. The vein system can be observed over a 259 m strike length ranging in widths from 1m to 3 m.
