Montero Completes Drilling of Target A

at The Isabella Gold Silver Project in Chile

Toronto, Ontario – February 2, 20 21 – Montero Mining and Exploration Ltd. (TSX-V: M ON) (“Montero” or the

“Company”) has completed 1,096 m of a planned 2,800 m diamond drill program at its Isabell a Gold Silver Project

(“Isabella”) in Chile. At Isabella 2, 600 m of drilling is planned to test gold silver mineralization within 4 separate ve in

targets and 200 m to test for breccia -type base -metal mineralization in sedimen ts adjacent to the granite contact .

Drilling is now complete at Target A and the drill rig has been moved to Target C where 2 holes will be completed

before moving to Target B and Target D. Target A drill core is being logged and is being dispatched for assay once core

logging is compl eted. Drilling is be ing carried out by Mountain Drilling Limitada based in La Serena, Chile , and to

adhere to Covid-19 safety protocols, have set up a camp at site to reduce interaction with the local community.

Dr Tony Harwood, President o f Montero commented : “The maiden drill program at Isabella has progressed well with

drilling completed at Target A intercepting quartz veins with visib le sulphides in all holes. The drill rig has be en moved

to Target C where 2 drill holes will test below a series of northeast trending quartz veins exposed and historically mined

pits where surface sampling returned up to 48 g/t Au and 263 g/t Ag.”

Target A - Isabella West Drilling

The Company completed the planned 10 diamond drill holes for a total of 1,096 m. Drilling tested a series of

northwest-trending quartz veins along approximately 600 m of strike length at a 25-50 m vertical depth (Figure 2).

Montero geologists report that quartz veins with visible sulphides have been intersected in all drill holes (Figure 3

and Figure 4). The drill core is HQ diameter and is being logged and cu t for sampling by Montero geologists at the

company facility in the village of Hualane . Selected intervals of quartz veins and altered granite host -rock have been

half-core sampled at 1 m intervals for assay with eac h batch of 25 samples to include 1 certi fied reference standard

and a sample blank. The samples are being hand delivered by Montero p ersonnel to the Andes Analytical Assay lab

in Santiago for assay.
