Tocvan Provides Gran Pilar Gold-Silver Project Update Advancing Pilot Mine Development and Drilling on South Block

Executive Summary

• Tocvan Ventures reports significant progress preparing the Gran Pilar Gold‑Silver Project for pilot‑scale production and an expanded drilling program.
• Site work includes condemnation drilling, installation of water monitoring wells, a newly built 4.8 km access road, drill pad preparation, and fencing of the pilot‑mine area.
• The company is awaiting assay results from recent North Block drill holes and channel samples, with results expected in February, which will guide further resource delineation.

Key Details

• Site Preparation Activities
• Condemnation drilling to clear development zones.
• Installation of water monitoring wells for environmental compliance.
• Completion of a new 4.8 km access road and preparation of drill pads on the Southern block.

• Fencing of pilot‑mine site and positioning of essential equipment.

• Exploration Drilling Plans

• Drill rig returned to Gran Pilar this week to commence infill and step‑out drilling aimed at expanding mineral resources.

• Targeted drilling on both South Block (extension of historic Main Zone) and North Block (3.2 km × 1.5 km alteration zone).

• Survey & Assay Work

• Magnetic drone survey over the North Block scheduled for completion this week; results expected in February.

• Assay results pending from initial North Block drill holes and recent channel sampling on both blocks, anticipated to be released shortly.

• Historical Drill Highlights (for context)

• South Block: 19.4 g/t Au over 3.1 m (Feb 25 2025), 5.4 g/t Au over 6.1 m (May 7 2025).
• North Block: 5.6 g/t Au & 106 g/t Ag chip sample (Oct 19 2023).

• Multiple historic diamond and RC drill intercepts ranging from 0.5 g/t to >100 g/t Au/Ag across 2020‑2025 campaigns.

• Metallurgical Results (recent)

• Bulk sample leaching: 62 % gold recovery over 46 days; head grade 1.9 g/t Au, 7 g/t Ag; extracted grade 1.2 g/t Au, 3 g/t Ag.
• Agitated bottle‑roll test: 80 % Au and 94 % Ag recovery in 24 h.

• Gravity‑leach tests on composite samples: 95‑99 % Au and 73‑97 % Ag recovery.

• Management Quote

• “We are excited with the momentum building at Gran Pilar as we move toward pilot production and further resource delineation,” said Brodie Sutherland, CEO.
