CALGARY, AB / ACCESS Newswire / September 16, 2025 / Tocvan Ventures Corp. ("Tocvan" or the "Company") (CSE:TOC)(OTCQB:TCVNF)(WKN:TV3/A2PE64), a leading exploration and development company focused on gold and silver projects in Sonora, Mexico, is pleased to announce the initiation of field work and an airborne magnetics survey at its flagship Gran Pilar Gold Silver Project. This marks a significant step forward in the Company's exploration and pilot mine programs, with preparations for upcoming drilling and trenching activities set to begin shortly.

Field work has already started with precision and purpose, the field work encompasses advanced geological mapping, targeted sampling, and sophisticated geophysical surveys aimed at pinpointing high-potential targets across the vast and highly prospective Gran Pilar district. Elevating the program to new heights, the airborne magnetics survey is already in flight, harnessing technology to uncover hidden structural features and mineral-rich zones that could redefine the project's scope. This powerful, non-invasive tool will generate critical insights, sharpening our exploration strategy and setting the stage for further resource growth.

In tandem with field activities, Tocvan is fast-tracking preparations for an ambitious drilling and trenching campaign, slated to commence before the end of the month. These high-energy activities will zero in on emerging mineralization hotspots, building on our track record of discoveries to expand resources and fast-track the path to production. With near-term pilot mining on the horizon, Gran Pilar is positioned as a cornerstone asset poised to deliver upside in one of the globe's most favorable mining jurisdictions.

"We are excited to kick off this next phase of exploration at Gran Pilar, leveraging advanced geophysical methods to unlock the full potential of this promising district," said Brodie Sutherland, CEO of Tocvan Ventures Corp. "The airborne magnetics survey, combined with our upcoming drilling and trenching, represents a strategic approach to rapidly advance our understanding of the mineralization and move closer to realizing value for our shareholders through exploration discovery and pilot mine production. Sonora continues to be a prime jurisdiction for gold and silver exploration, and we are committed to delivering results through disciplined and innovative progression of the project."

Tocvan has secured full permit approval for a 10-year pilot mine facility at its Gran Pilar Gold-Silver Project in Sonora, Mexico, a mine-friendly jurisdiction that positions the company for near-term production and early cash flow generation amid record-high gold prices. The fully permitted operation features an initial 50,000-tonne capacity heap leach pad within a compact 4.5-hectare infrastructure footprint, including a hydrometallurgical processing plant that employs sodium cyanide leaching with a 60-90 day retention cycle. Targeting high-grade ore from recent drilling intercepts and surface trenches-metallurgical tests indicate strong recovery rates of 95-99% for gold and 73-97% for silver, with an initial bulk sample achieving 62% gold recovery over 46 days, enabling the pilot to validate extraction economics and support expansion across the 21 km² property's South and North Blocks. This milestone, complemented by approvals for 45 drill pads and 67 trenches, accelerates Tocvan's transition from exploration to development, maximizing shareholder value through aggressive advancement of high-grade zones on 100% controlled ground.

Tocvan remains well-positioned with a strong balance sheet and a dedicated team of local experts to execute this program efficiently. Work planned will be conducted on 100% controlled ground. The Company will provide updates as results become available.

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.

The ALS Hermosillo and North Vancouver facilities are ISO 9001 and ISO/IEC 17025 certified. 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. 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.
