Tocvan Announces Discovery of Two New Target Areas With Historic Underground Workings at North Block Gran Pilar Gold-Silver Project
Executive Summary
- Tocvan Ventures announced the discovery of two new historic underground workings within the North Block of its Gran Pilar Gold‑Silver Project, expanding the known mineralized corridor in the 3.2 km North Alteration Zone.
- The newly identified targets are located ~700 m from existing drill zones and exhibit strong phyllic and argillic alteration with silicified vein breccia, indicating potential high‑grade gold‑silver veins.
- Company plans immediate trenching and drilling to delineate these targets, integrating them into its broader development strategy for Gran Pilar, which already includes a permitted 50,000‑tonne pilot mine.
Key Details
- Target Areas:
- Area 1: ~60 m exposed adits/shafts with silicified vein breccia and intense phyllic alteration; 700 m west of current permitted drill targets.
-
Area 2: ~50 m historic shafts and waste dumps showing argillic alteration and quartz veining; 700 m north of prior high‑grade samples.
-
Assay Status: Channel and grab samples collected from both areas; assay results pending.
-
Historical High‑Grade Context:
- 3.2 g/t Au & 1,225 g/t Ag sample located 800 m NE of new targets.
-
5.6 g/t Au & 106 g/t Ag chip sample 1,100 m SW of new targets.
-
Geological Setting: Targets lie within the North Alteration Zone (3.2 km × 1.5 km) characterized by extensive alteration and vein‑hosted mineralization trending NW‑SE, consistent with regional epithermal systems in Sonora.
-
Planned Work:
- Immediate trenching and core drilling to delineate targets.
- Ongoing integration of new surface mapping data with magnetic and other geophysical datasets to refine drill target selection.
-
All upcoming work will be conducted on 100 % controlled ground.
-
Company Context:
- Gran Pilar Project covers >22 km² with two primary zones (South Block – already drilling, North Block – largely undrilled).
- Recent drilling successes at South Block include: 19.4 g/t Au over 3.1 m (Feb 2025), 5.4 g/t Au over 6.1 m (May 2025), and 136 g/t Ag over 10.7 m (June 2025).
-
Pilot mine facility (50,000‑tonne) fully permitted; metallurgical tests show up to 99 % Au and 97 % Ag recovery.
-
Financial Position: Company states it has a strong balance sheet to fund the upcoming exploration program.
