TOCVAN SECURES FULL PERMIT APPROVAL FOR PILOT MINE FACILITY AT GRAN PILAR GOLD-SILVER PROJECT
Tocvan Ventures Corp. has received permit approval for the development of a 50,000-tonne pilot mine facility at its flagship Gran Pilar gold-silver project in Sonora, Mexico. This milestone, combined with the previously announced drilling and trenching permits, marks a significant step forward in advancing the project toward production.
Highlights:
Permit for 10-year pilot mine facility approved;
50,000-tonne-capacity heap-leach pad;
4.5-hectare infrastructure layout with hydrometallurgical processing facility;
Fully permitted for pilot mine development and exploration across 100-per-cent-controlled Gran Pilar;
Operational goals for pilot:
50,000 tonnes;
1.2 grams per tonne gold;
70-per-cent recovery.
The approved pilot mine facility will allow Tocvan to process up to 50,000 tonnes of material, enabling the company to test and optimize extraction methods while generating early cash flow potential. This permit complements the recently secured approvals for 45 drill pads and 67 trenches across the 100-per-cent-controlled, 21-square-kilometre expansion area, which support over 30,000 metres of drilling capacity to target high-grade gold and silver zones. Recent drilling successes, including 6.1 m of 5.4 g/t Au and 39 g/t silver within 41.2 m of 1.0 g/t Au and 10 g/t Ag (JES-25-114, announced May 7, 2025), and 3.1 m of 19.4 g/t Au within 106.6 m of 0.6 g/t Au near surface (announced Feb. 25, 2025), underscore the project's robust potential.
"We are thrilled to receive this permit approval for the pilot mine facility, a critical component in our strategy to fast-track Gran Pilar toward production," said Brodie A. Sutherland, chief executive officer of Tocvan Ventures. "This approval, alongside our extensive drilling and trenching permits, positions us to aggressively advance exploration and development while leveraging record-high gold prices to maximize shareholder value. Sonora's mine-friendly environment and our team's commitment to operational excellence make this an exciting time for Tocvan."
The pilot mine facility will focus on processing material from high-grade zones identified through continuing exploration. Metallurgical studies have already demonstrated strong recovery rates, with 62-per-cent gold recovery over a 46-day leaching period and up to 99-per-cent gold recovery in gravity recovery tests, further validating the project's economic potential. The approved trenching program will support systematic channel sampling and structural analysis to optimize material for the pilot mine, ensuring efficient operations. The company intends to focus exploration and pilot mine development exclusively on its 100-per-cent-controlled ground, maximizing shareholder value and showcasing the broader upside potential.

Quality assurance/quality control
Rock and drill samples were shipped for sample preparation to ALS Ltd. in Hermosillo, Sonora, Mexico, and for analysis at the ALS laboratory in North Vancouver. The ALS Hermosillo and North Vancouver facilities are ISO 9001 and ISO/IEC 17025 certified. Gold was analyzed using 50-gram nominal weight fire assay with atomic absorption spectroscopy finish. Overlimits for gold (greater than 10 g/t) were analyzed using fire assay with a gravimetric finish. Silver and other elements were analyzed using a four-acid digestion with an ICP finish. Overlimit analyses for silver (greater than 100 g/t) were reassayed using an ore-grade four-acid digestion with ICP-AES finish. Control samples comprising certified reference samples and blank samples were systematically inserted into the sample stream and analyzed as part of the company's robust quality assurance/quality control protocol.

The ALS Hermosillo and North Vancouver facilities are ISO 9001 and ISO/IEC 17025 certified. Gold and multielement analysis of soils was completed by aqua regia digestion and ICP-MS finish using a 50-gram nominal weight. Overlimit gold values greater than one g/t were reassayed with a more robust aqua regia digestion and ICP-MS finish. Overlimit analyses for silver (greater than 100 g/t) were reassayed using an ore-grade four-acid digestion with ICP-AES finish. Control samples comprising blank samples and certified reference materials were systematically inserted into the sample stream and analyzed as part of the company's robust quality assurance/quality control protocol.
