Tocvan Advances Drilling, Trenching, and Pilot Mine Preparation, Mobilizing Equipment to North and South Blocks at Gran Pilar Gold-Silver Project

Rhea-AI Summary

Tocvan Ventures (OTCQB:TCVNF) mobilized equipment to the North and South Blocks of the Gran Pilar gold-silver project in Sonora, Mexico to prepare for trenching, road upgrades and a pilot-mine. The first drill rig will move to the North Alteration Zone to begin an initial 2,000m program, while an initial 8,000m program is planned on the South Block.

The company says it is fully permitted for 67 trenches, 30,000m+ of drilling and a 10-year pilot mine, remains funded for activities, and expects trenching, geophysical results, and 3,000–5,000m drilled by end of Q4 2025.

CALGARY, AB / ACCESS Newswire / October 20, 2025 / Tocvan Ventures Corp. ("Tocvan" or the "Company") (CSE:TOC)(OTCQB:TCVNF)(WKN:TV3/A2PE64), is pleased to announce the mobilization of equipment to both the North and South Blocks of its flagship Gran Pilar Gold-Silver Project in Sonora, Mexico. This marks a significant step forward in preparing the site for upcoming drilling, trenching activities, and ground preparation for the planned pilot mine operation. The first drill rig is also set to mobilize to the North Alteration Zone, positioning the Company to accelerate its exploration and development efforts.

The mobilization follows recent advancements at Gran Pilar, where surface work and geophysical surveys have recently highlighted new targets across the Project. Bulldozers will focus on road access improvements, site clearing, and trenching to expose new key mineralized zones. These preparations are essential for the inaugural drill program on the North Block, which represents an underexplored expansion area with highly promising geochemical and geological indicators. On the South Block, activities will support the pilot mine setup, trenching and drilling. All activities will focus on new target areas across the 100% controlled ground where Tocvan is fully permitted for 67 trenches, over 30,000 meters of drilling and a 10-year pilot mine facility.

Looking ahead, Tocvan anticipates several key milestones and announcements, including:

• Commencement of the first-ever drill program at the North Block (Initial 2,000 meters planned).

• Road access upgrades and trenching results from the South Block.

• Commencement of drill program across South Block (Initial 8,000 meters planned).

• Targeting completion of 3,000 to 5,000 meters drilling by end of Q4.

• Clearing and ground preparation updates for the pilot mine on the South Block.

• Completion and results from geophysical surveys on the North Block.

• Interpretation and inversion modeling of geophysical data from North and South Blocks.

• Ongoing surface geochemical, geological and structural mapping and sampling results from the North Block.

• Eastern extension of surface geochemical sampling and geological mapping of the South Block.

• Permitting for two years of drilling and trenching at the El Picacho Gold Project.

"We are excited to ramp up operations at Pilar with this mobilization, which sets the stage for a transformative phase of exploration and production," said Brodie A. Sutherland, CEO of Tocvan Ventures. "The North Block holds tremendous untapped potential, and combined with our progress on the South Block, we are well-positioned to deliver value through discovery and near-term cash flow from pilot operations."

The Company remains funded for these activities and continues to prioritize safe, efficient, and environmentally responsible operations in partnership with local communities.

Quality Assurance / Quality Control

Rock and Drill samples were shipped for sample preparation to ALS Limited 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. Over limits for gold (>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. Over limit analyses for silver (>100 g/t) were re-assayed 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.

Gold and multi-element analysis of soils was completed by aqua regia digestion and ICP-MS finish using a 50-gram nominal weight. Over limit gold values greater than 1 g/t were re-assayed with a more robust aqua regia digestion ad ICP-MS finish. Over limit analyses for silver (>100 g/t) were re-assayed using an ore-grade four-acid digestion with ICP-AES finish.
