Mergers & Acquisitions Property Options & Staking

MONTERO ACQUIRES ISABELLA GOLD SILVER PROJECT IN CHILE

Toronto, Ontario – August 5, 2020 – Montero Mining and Exploration Ltd. (TSX-V: MON) (“Montero” or

the “Company”) has signed a Binding Purchase and Sale Agreement (“Agreement”) to acquire a 100%

interest in a private Chilean company (“ ChileCo”) which holds various mineral rights to exploration

claims that make up the Isabella Gold Silver Project ( “Project”) in Chile. Isabella’s exploration claims

cover an area of 67km2. The Agreement is subject to corporate and legal process in Chile and regulatory

approval.

Dr. Tony Harwood, President and Chief Executive Officer of Montero commented, “Montero has secured

the highly prospective I sabella Gold Silver Project in Chile where the Company can util ize its gold silver

exploration, discovery and dev elopment expertise in a tier one mining jurisdiction. The Company is

assessing previous exploration data with a view to carrying out a drill program in the fall of 2020. ”

The Isabella Gold Silver Project is located in the Southern Coastal Range of Chile approximately 200 km

south of Sa ntiago and has excellent year -round access. The Coastal Range contains numerous gold and

copper occurrences hosted within a package of intermediate in trusives, sediments and vol canics of

Mesozoic age.

The Isabella Gold Silver Project is located regionally south of Yamana’s Minera Florida gold mine and

north of an extensive regional gold area being explored by Fresnillo. However, these operations do not

confirm the mineral potential of the Isabella properties. The Isabella region has seen little modern

exploration and most occurrences remain undrilled.

The Isabella Gold Silver Project area hosts numerous structurally controlled quartz veins that have been

mapped over an area of approximately 12 km long and 4 km wide. A review of field reports on mapping

and sampling prepared by the previous owner indicate high gold - silver concentrations within quartz

veins with values of up to 48 g/t gold and 629 g/t silver.

The samples collect ed where grab samples of exposed vein material and are not considered

representative of the overall concentration of mineralizat ion in any particular vein. Samples were

collected in accordance with industry best practices and analyzed by ALS Chile under th e supervision of

a qualified person. No independent sampling has been completed by Montero.

The veins form part o f an extensive regional polymetallic Au -Ag vein and breccia system occurring in

dilational fractures in the granite and along contacts with older sediments. Prior exploration at Isabella

by the previ ous operator in cludes surface mapping, rock sampling, tre nching, and airborne magnetics .

No drilling in the Isabella district has been carried out to date.

Under the terms of the Agreement, Montero has acquired a 100% interest in ChileCo which holds all the

mineral interests to the Isabella Gold Silver Project. ChileCo was purchased for a nominal amount and by

taking over the earn-in obligations of cash payments totaling US$ 450,000 to be made by August 2022.

ChileCo directly holds 100% of the mineral rights to 18 km2 of mineral claims and h as two subsidiaries

with 49 km2 under option agreeme nts. In Subsidiary 1 Montero has an 85% interest in Isabella West

mineral claims while in Subsidiary 2 Montero is earning an 85% interest in Isabella East mineral claims.

The mineral claims held by both subsidiaries are subject to joint venture and mining option agreements

with local parties. Montero is reviewin g several drill target areas that have be en identified and

permitted for drilling by the previous owners in order to commence a drill program.
