Tocvan begins fieldwork, magnetics survey at Gran Pilar

Mr. Brodie Sutherland reports TOCVAN ANNOUNCES COMMENCEMENT OF FIELD WORK AND AIRBORNE MAGNETICS SURVEY AT GRAN PILAR GOLD SILVER PROJECT; DRILLING AND TRENCHING PREP ACCELERATE DISCOVERY & PILOT MINE PRODUCTION Tocvan Ventures Corp. has initiated fieldwork 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 coming drilling and trenching activities set to begin shortly. Fieldwork has already started with precision and purpose; the fieldwork 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 the company's 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 hot spots, building on the company's 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 favourable 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, chief executive officer of Tocvan Ventures. "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-to-90-day retention cycle. Targeting high-grade ore from recent drilling intercepts and surface trenches, metallurgical tests indicate strong recovery rates of 95 to 99 per cent for gold and 73 to 97 per cent for silver, with an initial bulk sample achieving 62-per-cent gold recovery over 46 days, enabling the pilot to validate extraction economics and support expansion across the 21-square-kilometre 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-per-cent-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-per-cent-controlled ground. The company will provide updates as results become available. 100-per-cent-controlled priority targets for trenching and drilling: South block main zone expansion: Follow-up on 2025 drill success: 19.4 grams per tonne Au over 3.1 metres within 106.6 metres of 0.6 g/t Au (Feb. 25, 2025, news release); 5.4 g/t Au over 6.1 metres within 41.2 metres of 1.0 g/t Au (May 7, 2025, news release); 136 g/t Ag over 10.7 metres within 42.7 metres of 41 g/t Ag (June 25, 2025, news release); South block (Nov. 12, 2024, news release): Placer corridor (900-metre strike length): Soil samples up to 21.2 g/t Au and greater than 2,000 g/t Ag; Placer source area: Soil samples up to 2.4 g/t Au and 22 g/t Ag; Rock samples up to 7.3 g/t Au and 389 g/t Ag; North block: North alteration zone (3.2-kilometre-by-1.5-kilometre area): Two-metre chip sample -- 5.6 g/t Au and 106 g/t Ag (Oct. 19, 2023, news release); Historic mine working sample -- 3.2 g/t Au and 1,225 g/t Ag (March 8, 2024, news release).

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.
