Drilling Of High-Grade Au-Ag Vein Targets At Isabella Gold Silver Property

TORONTO - Montero Mining and Exploration Ltd. reported that initial drill testing of the Isabella Au-Ag mineralized, quartz vein systems has commenced. The Isabella Properties are located approximately 200 km south of Santiago and 125 km south of Yamana’s Minera Florida mine in the Southern Coastal Range of Chile. The current drilling program will commence with an initial 1,200 meter program to test the vein system in priority target A. This property is situated immediately south of a small, locally operated mine.

Target A consists of multiple high-grade Au-Ag quartz veins that have been defined within a 75 m wide zone of altered granite extending 600 m along strike. Surface samples of vein material returned assays of up to: 8.53 g/t Au, 11.2 g/t Ag and 7.56 g/t Au, 16.8 g/t Ag. Trenches completed over 300 m strike length of the vein array returned: 6.92 g/t Au over 1 m, 2.88 g/t over 2 m, and 1.4 2g/t Au over 12 m (incl 3.53 g/t Au over 3 m). The vein array is contained within a broader zone of anomalous Pb defined as >100 ppm which is characteristic of the high-grade Au veins in the area. Based on the assay results Montero will drill 6-8 holes for a total 1,200 m to test veins along 600 m of strike length.

Vein targets B, C, D will be drill tested during Q1 2021 as part of a total 2,600 m initial drill program to test the Isabella vein systems. Montero and the drill company, Mountain Drilling Ltda., have implemented strict Covid-19 risk procedures during the drill program.
