MON Montero Mining and Exploration Ltd

Montero Mining and Exploration Ltd. (TSX-V: MON) (“Montero” or the “Company”) continues to consolidate its property holdings at the Avispa copper molybdenum project located in the Atacama Desert of northern Chile. The company has finalized the regulatory process for 200.8 km2 of exploration concessions that includes the original Avispa and recently awarded Abeja exploration concessions that were registered in 2021.

The company is also finalizing the regulatory process on an additional 270.5 km2 of Abeja concessions. The company expects the remaining regulatory processes to be completed during Q2 2022. Once completed the company would hold 100% ownership of a total of 473.3 km2 of exploration concessions in a well-defined late Paleocene to early Eocene Cu-Mo porphyry belt of northern Chile.

The Avispa property is located in a well-defined porphyry belt approximately 40 km north of BHP’s Spence Cu-Mo mine, KGHM’s Sierra Gorda Cu-Mo mine and the recently announced discovery at Sociedad Contractual Minera Búfalo (SCMB) Cerro Búfalo project in the Sierra Gorda district south of Avispa. The consolidated Avispa and Abeja concession are surrounded by major mining companies with exploration and mining concessions with groups including; Codelco Freeport, Glencor, Antofagasta, and SQM. Avispa is also 50 km west of Codelco’s Chuquicamata supergiant porphyry copper mine that occurs within a younger late Eocene – early Oligocene porphyry belt.

Dr. Tony Harwood, President and Chief Executive Officer of Montero commented, “With advancement of the regulatory process Montero will control a significant land package in this world class porphyry copper district. The presence of major companies such as Glencore, Freeport and Antofagasta actively exploring in the district makes Montero’s land package very prospective. The Company continues its mapping and sampling program and will provide updates.”

Planned Exploration Program Montero has completed a thorough investigation of historical information on exploration in this highly prospective area. The Company has planned an exploration program that includes; detailed geological mapping, surface sampling, ground and airborne geophysical surveys with the objective of defining drill targets. The Company has completed geological mapping and geochemical sampling transect along the San Salvador River at the southern margin of the Avispa and Abeja Property. This work will help establish the stratigraphic and structural framework to guide future exploration.

Previous companies to have explored Avispa include BHP that conducted limited drilling on the property at 2 km to 3 km spacing as part of a regional exploration program. Montero believes that there is potential for buried porphyry and porphyry-related deposits with smaller footprints than those sought by major companies.

Montero’s Chief Geologist, Marcial Vergara, has reviewed publicly available data on Avispa and has conducted a field visit. Marcial previously worked for Codelco and Anglo American, both major operating copper mining companies in Chile. Montero has adopted a prospect generator model at Avispa where it will de-risk the project and carry out limited exploration while seeking a partner to advance the project through the drill phase. This will provide Montero shareholders with exposure to the copper space while it continues to focus on the gold-silver potential of southern Chile.
