Masivo Silver begins phase I drilling at Cerro Colorado

Executive Summary

• Masivo Silver Corp. has launched Phase I of its diamond drill program at the Cerro Colorado project in Sonora, Mexico.
• The initial phase consists of approximately eight holes totaling 1,500 to 2,000 meters, designed to systematically test high-priority silver-copper targets identified through geological mapping and surface sampling.
• The program aims to validate the geological model, demonstrate continuity at depth, and potentially expand the footprint of mineralization for the structurally controlled silver-copper system.

Key Details

• Program Scope: Phase I includes approximately eight diamond drill holes with an estimated total depth of 1,500 to 2,000 meters.
• Strategic Objective: Systematically test high-priority silver-copper targets to validate the geological model and demonstrate continuity at depth for a system identified as at least 1.2 kilometers structurally controlled.
• Hole A: Targets a depth of 130 meters to hit polymetallic sulphides corresponding to a high chargeability (IP) anomaly at 100 meters below surface; potential for high Ag, Au, Cu, Pb, and Zn values.
• Hole B: Located ~500 meters northeast of Hole A, targeting a depth of 150 meters to test a high-chargeability anomaly and follow up on historic dump assays (1,840 g/t Ag, 4.82 g/t Au, 3.06% Cu, 4.55% Pb, 2.92% Zn).
• Holes C, D, and E: Located between Holes A and B to test the high-chargeability anomaly within the same mineralized structure; Holes C and E target 150 meters, while Hole D targets 200 meters.
• Holes F and G: Located northeast of Hole B, targeting depths of 150 to 300 meters to test the high-chargeability anomaly and assess continuity along a southwest-to-northeast trend.
• Hole H: Oriented southeast-to-northwest to target a secondary structural system perpendicular to the main trend; targets a depth of 120 meters to test Au-Cu-Ag mineralization observed in historic artisanal workings (historic values >20 g/t Au, 95 g/t Ag, 0.8% Cu).
• Historical Context (2015 Minera Gold Zone Drilling):
  • ETCC-15-01: 29.65m at 50.74 g/t Ag, 0.607% Zn, 0.131% Pb, 0.053% Cu, 0.062 g/t Au (48.80–78.45m), including 5.05m at 254 g/t Ag and 2.95m at 384 g/t Ag.
  • ETCC-15-04: 35.80m at 23.44 g/t Ag and 0.406% Zn (44.50–80.30m), including 3.15m at 159.06 g/t Ag and 0.60m at 577 g/t Ag.

Notable Quotes

• "The start of drilling at Cerro Colorado is a pivotal moment for Masivo. We are now systematically testing what we have evidence at surface of being at least 1.2 kilometres structurally controlled, expanding silver-copper system with clear evidence of scale at surface. These first holes are designed to validate our geological model and demonstrate continuity at depth. We believe this program has the potential to materially expand the footprint of mineralization and unlock significant value for shareholders." — David G. Coburn, CEO
