[{"type":"text","content":" TORONTO, April 06, 2021 (GLOBE NEWSWIRE) -- Montero Mining and Exploration Ltd. (TSX-V: MON) has completed a total of 2,088 meters of diamond drilling and testing of 4 vein target areas (Table 1) at its Isabella gold-silver project in Chile. A total of 19 drill holes have been completed to date where multiple quartz veins and enclosing leucogranite microgranite were intersected in 17 holes. Half-core samples have been submitted to Andes Analytical Assay (AAA) and check assays to ALS Chile, both in Santiago. Montero has received initial assay results for vein Target area A. Dr. Tony Harwood, President of Montero commented, “Shallow drilling at Target A intercepted consistent intersections of quartz veins enclosed in a quartz-sericite-pyrite altered leucogranite with anomalous Au Ag values. Assay results from drill holes completed on Targets B, C and D are expected shortly.” At Target A, a total of 10 HQ size diamond drill holes were completed over a total of 1,095 meters. Maximum values of 1.88 g/t Au and 16 g/t Ag were reported from the veins at Target A while assays from the adjacent altered leucogranite also contains low to anomalous Au Ag mineralization.

No significant assay results in drill holes number ISBN20-05, 09 and 10. The quartz veins sampled from drill core are consistent with Au enrichment and concomitant enrichment of Pb and Ba in reported assays of surface vein samples. The enrichment of Ba (4885 ppm), Pb (3346 ppm) and also Mo (262 ppm) and Sb (101 ppm) suggests a complex mineral system with perhaps overprinting of fluid types. This is particularly suggested by a 1 m assay of 0.14 g/t Au, 3 g/t Ag, and 4,885 ppm Ba from a quartz vein at 128.5 m in hole ISB20-08 which would infer the possibility of a deep mineral system.
