Tocvan Announces Positive Surface Results From North Block And Drill Program Update At Gran Pilar
Executive Summary
- Initial surface sampling on the North Block of Gran Pilar returned exceptionally high silver assays up to 134 g/t Ag (4.3 oz/t), confirming strong epithermal gold‑silver potential.
- Ongoing drill program has logged ~1,300 m across five holes; assay results are pending and will be released when available.
- Road building and trenching preparations continue in the South Block to support the next phase of pilot production testing.
Key Details
- Surface Sampling Highlights (North Block)
- Silver values as high as 134 g/t Ag (4.3 oz/t).
- Gold assays ranging from 0.0025 ppm to 5.6 ppm; silver from 0.25 ppm to 1,225 ppm.
- Strong pathfinder element anomalies: arsenic, antimony, lead, zinc, copper, molybdenum – typical of epithermal systems.
-
Alteration signatures (sericitization, chlorite‑carbonate‑pyrite, carbonate, argillic, sulfidation) co‑locate with high‑grade Ag zones.
-
Exploration Indices
- SPI (Silver‑Polymetallic Index) – highlights Ag‑Pb‑Zn‑Sb‑As corridors.
- GPI (Gold‑Pathfinder Index) – emphasizes Au‑As‑Sb‑Pb‑Bi halos.
-
Combined Overall Composite Index used to rank samples for integrated Au‑Ag potential; top-ranked samples: 334067, 334066, 494827.
-
Drill Program Status
- Approximately 1,300 m drilled in five holes targeting resource discovery zones on the North Block.
-
Assay results are pending; release scheduled as data become available.
-
South Block Activities
-
Continued road construction and preparation for trenching and drilling ahead of pilot‑production set‑up.
-
Historical Context (for reference)
- Prior drill highlights at Gran Pilar include multiple high‑grade intercepts (e.g., 83.5 m @ 1.3 g/t Au, 64.9 m @ 1.2 g/t Au with 21.6 g/t Au & 209 g/t Ag).
-
Bulk sample testing demonstrated 62 % gold recovery and 7 g/t Ag head grade over a 46‑day leach, with rapid agitated leach recoveries of 80 % Au and 94 % Ag in 24 h.
