Tocvan completes airborne magnetic survey at Gran Pilar
TOC · Price
Executive Summary
- Tocvan Ventures completed a high‑resolution drone‑based airborne magnetic survey of the entire Gran Pilar gold‑silver project, revealing subsurface structures that align with known mineralization and identifying new target zones for expansion.
- The company disclosed extensive historic and recent drilling results (2020‑2025) showing multiple high‑grade Au/Ag intercepts, supporting a strong resource potential across South, North, and Central blocks.
- Metallurgical testing demonstrated very high metal recoveries (up to 99 % Au and 97 % Ag), reinforcing the economic viability of future pilot‑scale production.
Key Details
- Survey Scope: 70 east‑west lines, 100 m spacing; total 235.66 km line length; conducted by Zonge International Inc.
- Data Products Delivered: Total Magnetic Intensity (TMI), TMI reduced to the pole (TMI‑RTP), first vertical derivative (1VD) of TMI‑RTP, tilt derivative of TMI‑RTP.
- Interpretation Benefits: Enables integration with existing geochemical, geological and drill data; guides target refinement for the ongoing 20,000 m drill program and pilot mine development.
- CEO Quote: “The high‑quality data sets a strong foundation for our next phases of analysis… these structures have the potential of expanding our targets across the area.”

Historic Drilling Highlights (2024‑2020)
- 2024 RC: 42.7 m @ 1.0 g/t Au, including 3.1 m @ 10.9 g/t Au.
- 2022 Phase 3 Diamond: 116.9 m @ 1.2 g/t Au, including 10.2 m @ 12 g/t Au & 23 g/t Ag.
- 2020 Phase 1 RC: 24.4 m @ 2.5 g/t Au & 73 g/t Ag; 1.5 m @ 33.4 g/t Au & 1,090 g/t Ag.
Bulk Sample Metallurgy
- Gold Recovery: 62 % overall (46‑day leach); fine fraction test – 80 % gold recovery in 24 h.
- Silver Recovery: 94 % in rapid 24 h test; bulk sample extracted grade 3 g/t Ag (head grade 7 g/t).
- Additional Tests: Gravity‑agitated leach on composites – 95‑99 % Au, 73‑97 % Ag recovery; drill core composite at 120 m depth gave 99 % Au & 73 % Ag.
Exploration Targets
- South Block Main Zone Expansion: Follow‑up on 2025 drill hits (19.4 g/t Au, 5.4 g/t Au, 136 g/t Ag).
- Placer Corridor (900 m strike): Soil samples up to 21.2 g/t Au & >2,000 g/t Ag.
- North Alteration Zone: Chip sample 5.6 g/t Au & 106 g/t Ag; historic mine sample 3.2 g/t Au & 1,225 g/t Ag.
Next Steps
- Detailed magnetic data analysis and inversion modelling to estimate depth/geometry of sources.
- Correlation with geological, geochemical, and existing drill datasets.
- Refinement of exploration targets ahead of the planned 20,000‑m drilling campaign and pilot mine permitting.
