Montero Consolidates Property Holdings at the

Avispa Copper-Molybdenum Property, Chile

Toronto, Ontario – March 14. 2022 – 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 km 2 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 regula tory process on a n additional 270.5 km2 of Abeja concessions. The

company expects the remaining regulatory processes to be completed during Q2 2022. Once completed the

company wo uld 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 disco very 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 mini ng conce ssions 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. Ton y Harwood, President and Chief Executive Offi cer of Montero comment ed, “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 dist rict 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 Comp any has planned an explora tion program that includes; detailed geological mapping, surface

sampling, ground and airborne geophysical surveys with the object ive of defining drill targ ets. 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 establ ish the stratigraphic and structural f ramework

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 regio nal exploration program. Montero beli eves 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 wo rked for Codelco and Anglo American , both major operating copper mining

companies in Chile. Montero has adopted a prospect generator model at Avispa wh ere 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 shareholder s with exposure to the copper space while it continues to focus on th e gold -silver

potential of southern Chile.
