Tocvan Announces Initial Findings From Drone Magnetic Survey At Gran Pilar Gold-Silver Project: Discovery Of Structural Complex In South Block Aligns With Permitted Drill Targets

Executive Summary

• Tocvan Ventures announced preliminary results from a drone‑based airborne magnetic survey over the South Block of its Gran Pilar project, identifying a 2.0 × 2.5 km structural complex that correlates with high‑grade surface geochemistry.
• The new structural corridor and associated magnetic anomalies generate several high‑priority drill targets; drilling, trenching and additional surface sampling are slated to begin shortly.
• The company highlighted historic drill intercepts (e.g., 19.4 g/t Au over 3.1 m) and recent metallurgical recoveries (up to 99% Au, 97% Ag), underscoring the project's near‑term discovery potential.

Key Details

• Survey Scope: ~224 line‑kilometers of drone magnetic data covering the Gran Pilar property; processing continues for the North Block.
• Structural Complex: Prominent intersecting fault corridor spanning ~2.0 km × 2.5 km in the South Block, with magnetic signatures indicative of magmatic activity.
• Geochemical Correlation: Aligns with historic surface assays up to 21.2 g/t Au and >2,000 g/t Ag; suggests deeper‑seated epithermal mineralization.
• New Targets: Expanded “Placer Corridor” targets in South Block; additional unnamed magnetic anomalies to the east/southeast awaiting mapping and sampling.
• Upcoming Work: Surface sampling underway; drilling and trenching to commence shortly on 100% controlled ground.
• Historic Drill Highlights (referenced):
• 19.4 g/t Au over 3.1 m (Feb 25 2025)
• 5.4 g/t Au over 6.1 m (May 7 2025)
• 136 g/t Ag over 10.7 m (June 25 2025)
• Recent Diamond/RC Drill Intercepts (2025):
• 83.5 m @ 1.3 g/t Au (incl. 9.7 m @ 10.3 g/t Au) – Mar 11 2025
• 97.4 m @ 0.7 g/t Au (incl. 36.3 m @ 1.6 g/t Au) – Mar 19 2025
• 64.9 m @ 1.2 g/t Au (incl. 3.0 m @ 21.6 g/t Au & 209 g/t Ag) – Mar 26 2025
• Metallurgical Results:
• Bulk sample: 62% gold recovery over 46‑day leach; head grade 1.9 g/t Au, 7 g/t Ag; extracted grade 1.2 g/t Au, 3 g/t Ag.
• Bottle‑roll test: 80% Au, 94% Ag recovery in 24 h.
• Gravity‑leach composites: 95–99% Au, 73–97% Ag recovery; up to 99% Au & 73% Ag from 120 m depth core composite.
• Corporate Positioning: Strong balance sheet; 100% controlled land; 51% JV with Colibri Resources; 100% owned Picacho project in Caborca Trend.
