Tocvan Ventures Corp. reports exploration and development activity for gold-silver projects in Sonora, Mexico, led by the flagship Gran Pilar Gold-Silver Project. Company updates commonly cover reverse-circulation and core drilling, surface sampling, trenching, geophysical surveys, target generation, and pilot-scale development work across areas such as the Main Zone, South Block, El Mezquite, and other mineralized trends.
Recurring news also includes assay and metallurgical results, community access agreements, use of exploration technologies such as drone magnetic surveys and AI prospectivity mapping, advisor appointments, and financing transactions used to advance the company's Mexican gold projects and working capital.
Tocvan Ventures (OTCQB:TCVNF) outlined a phased plan to advance its fully permitted, 50,000‑tonne heap‑leach pilot mine at the Gran Pilar gold-silver project in Sonora, Mexico, targeting a first gold-silver doré pour in Q4 2026. The company holds a 10-year pilot mine permit (secured August 2025) and a 6-year Community Agreement (executed May 2026), providing operating and expansion visibility. According to Tocvan, construction is underway with heavy equipment mobilized in April 2026, site preparation and leveling completed, and leach pad and containment pond construction in progress. A 1.76‑hectare engineered pad, local crushing, and a 5-column carbon-adsorption circuit are planned, with pilot operations aiming for about 70% gold recovery over 60–90 day leach cycles. Six defined phases run through late 2026, culminating in initial revenue and detailed cost and metallurgical data to inform potential commercial-scale development.
Tocvan (OTCQB:TCVNF) signed a definitive deal to acquire the remaining 49% interest in the original Pilar concessions, consolidating 100% ownership of the Gran Pilar gold-silver project in Sonora, Mexico. Consideration totals C$3.6 million in cash plus a 1% NSR royalty to Colibri, with a C$1.0 million royalty buyback right.
Closing is subject to Canadian Securities Exchange and other customary approvals. The concessions host the Main Zone and form part of a >21 km² land package with extensive historic drilling, recent drill highlights and bulk sample metallurgical recoveries of up to 99% gold and 97% silver on composites.
Tocvan Ventures (OTCQB:TCVNF) reported exploration drilling at its 100%-owned Gran Pilar gold-silver project in Sonora, Mexico, intersecting three new mineralized zones beyond the Main Zone.
Over 6,200m of a 20,000m fully funded program are complete, with 19 holes pending, and a 50,000‑tonne heap-leach pilot mine advancing toward 2026 commissioning.
Tocvan (OTCQB:TCVNF) reported new surface results from the Bojorquez Target at the Gran Pilar gold-silver project in Sonora, Mexico, about 3 km east of the Main Zone.
Rock sampling (79 samples) outlined a 1,200m by 700m anomalous area with notable gold, silver, base-metal and pathfinder values, supporting a sizable new drill target.
Tocvan (OTCQB:TCVNF) reported progress at its fully funded 20,000 m drill program at the Gran Pilar gold-silver project in Sonora, Mexico. Over 5,300 m have been drilled, with assays pending for 21 holes totaling 4,400 m.
The company signed a long-term community agreement granting surface access and supporting exploration and pilot production. Tocvan ordered processing plant equipment for a fully permitted 50,000‑tonne pilot mine facility and is upgrading one RC rig to core drilling while seeking a third rig. Historic underground workings have been mapped on the South Block, along the El Mezquite trend.
Tocvan Ventures (OTCQB:TCVNF) mobilized a dozer, excavator and haul truck to its Gran Pilar gold-silver project in Sonora to accelerate trenching, road works and pilot-scale development while continuing a fully funded 20,000-meter drill program.
Bulk test material has been sent for pilot optimization and recent surface sampling returned up to 1.2 g/t Au and 11 g/t Ag, with multiple high-grade historic drill and metallurgical results supporting rapid project de-risking.
Tocvan (OTCQB:TCVNF) mobilized a second Reverse Circulation drill rig to the Gran Pilar project on April 6, 2026, accelerating a fully funded 20,000‑meter program. The second rig doubles monthly meterage capacity and enables parallel testing of multiple high‑priority targets, including a new South Block gold‑silver zone.
Recent highlights include step‑out hole JES‑26‑135 (22.9 m @ 0.6 g/t Au) and multiple historic and 2025 drill intercepts supporting resource expansion and a near‑term pilot mine pathway.
Tocvan Ventures (OTCQB:TCVNF) reports a new discovery in the South Block at Gran Pilar: RC hole JES-26-135 hit 22.9 m @ 0.55 g/t Au from surface including 6.1 m @ 1.61 g/t Au & 13 g/t Ag, plus a deeper 10.68 m @ 0.43 g/t Au at 122.0 m. The intercept lies 1,600 m from the Main Zone inside a 1,200 m magnetic anomaly with strong soil and rock gold-silver anomalies.
Drilling is part of a fully funded 20,000 m program (>2,400 m completed) and pilot-facility preparation drilling found no constraints for infrastructure siting.
Tocvan Ventures (OTCQB:TCVNF) completed a high-resolution drone magnetic survey across the Gran Pilar project on March 19, 2026, covering 235.66 line‑km on 70 east‑west lines spaced 100 m. The data maps TMI, TMI‑RTP, 1VD and tilt derivatives to refine structural targets.
Survey results highlight extensions of known mineralized structures, priority targets in the South and North blocks, and will feed magnetic inversion modelling to refine targets for an ongoing 20,000‑meter drill program.
Tocvan Ventures (OTCQB:TCVNF) announced a strategic partnership with VRIFY on March 13, 2026 to integrate VRIFY Predict (DORA) and VRIFY Present into exploration at the Gran Pilar gold-silver project in Sonora, Mexico.
The collaboration aims to use AI prospectivity mapping alongside Tocvan's drilling, geochemistry, and geophysics dataset to prioritize high-confidence targets and accelerate discovery.
