Tocvan Announces Maiden Drill Program Underway at North Block Gran Pilar Gold-Silver Project

Rhea-AI Summary

Tocvan Ventures (OTCQB:TCVNF) has started its maiden drill program at the North Block of the Gran Pilar gold‑silver project in Sonora, Mexico, targeting a 3.2 km by 1.5 km alteration zone.

Site prep is complete and an initial 2,000 m phase is underway with a proposed additional 3,000 m; the company is fully permitted for over 30,000 m of drilling. Surface assays reported include 5.6 g/t Au & 106 g/t Ag (2 m chip) and a historic working of 3.2 g/t Au & 1,225 g/t Ag. Tocvan integrates geophysics, mapping and geochemistry and plans to complete 3,000–5,000 m across both blocks by end Q4 2025.

CALGARY, AB / ACCESS Newswire / November 11, 2025 / Tocvan Ventures Corp. (the "Company" or "Tocvan") (CSE:TOC)(OTCQB:TCVNF)(WKN:TV3/A2PE64) is pleased to provide an update on its ongoing maiden drill program at the North Block of the Gran Pilar Gold-Silver Project in Sonora, Mexico. The program, which commenced following the mobilization of equipment in October, marks the first-ever drilling in this underexplored expansion area and is designed to test a 3.2 km by 1.5 km target zone exhibiting strong geochemical and geological indicators of mineralization.

To date, the Company has completed initial site preparations, including road access improvements and the establishment of the first drill pads. Drilling activities are progressing with an initial phase of 2,000 meters planned, focusing on high-priority targets within the North Alteration Zone. These zone have already yielded promising surface samples, including a 2-meter chip sample assaying 5.6 g/t Au and 106 g/t Ag, and a historic mine working sample returning 3.2 g/t Au and 1,225 g/t Ag.

Recent discoveries of two new mineralized targets with historic underground workings further underscore the potential of the area, featuring exposed vein breccia, phyllic and argillic alteration, and quartz veining across sections up to 60 meters.

"We are thrilled with the early progress of our maiden drill program at the North Block, which represents a significant step in unlocking the full potential of the Greater Pilar system," stated Brodie A. Sutherland, CEO of Tocvan Ventures. "The integration of geophysical surveys, surface mapping, and these new target discoveries has refined our approach, and we anticipate meaningful results that could expand our resource potential. Combined with advancements on the South Block, including trenching and pilot mine preparations, Gran Pilar is positioning Tocvan for near-term production and long-term growth."

The North Block forms part of the larger Gran Pilar project, spanning over 22 square kilometers and located in a highly prospective region known for porphyry/ epithermal gold-silver systems. The Company remains fully permitted for over 30,000 meters of drilling and is targeting completion of 3,000 to 5,000 meters by the end of Q4 2025 across both blocks.

Ongoing surface geochemical sampling, geological mapping, and geophysical data interpretation continue to support drill targeting. Tocvan will provide further updates as assay results become available and drilling advances.

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.
