Tocvan Drone Magnetic Data Strengthens Gold-Silver Targets Across Gran Pilar; Identifies Broad Zones for Expansion Potential

Executive Summary

• Tocvan Ventures completed a high‑resolution drone‑based airborne magnetic survey of the entire Gran Pilar Gold‑Silver Project in Sonora, Mexico.
• The survey covered 235.66 line‑kilometers (70 east‑west lines spaced 100 m apart) and identified subsurface features that align with known mineralization zones and extend into previously unexplored areas.
• Data analysis and magnetic inversion modeling will feed directly into the company’s ongoing 20,000 m drill program and pilot mine development plans.

Key Details

• Survey contractor: Zonge International, Inc.
• Survey scope: 70 east‑west flight lines, 100 m line spacing, total 235.66 line‑km.
• Data products generated: Total Magnetic Intensity (TMI), TMI Reduced to the Pole (TMI‑RTP), First Vertical Derivative (1VD) of TMI‑RTP, and Tilt Derivative of TMI‑RTP.
• Results indicate continuity of structural features associated with historic mineralization and reveal new targets in underexplored central and northern portions of the project.
• Planned next steps: detailed data analysis, integration with existing geological, geochemical, and drill datasets; magnetic inversion modeling to estimate depth, shape, and susceptibility of sources; refinement of exploration targets for the 20,000 m drill program and pilot mine development.
• CEO comment (Brodie Sutherland): “The high‑quality data sets a strong foundation for our next phases of analysis and interpretation…these structures have the potential of expanding our targets across the area.”
