TOCVAN ANNOUNCES ADDITION OF SECOND DRILL RIG AND ACCELERATES HIGH-PRIORITY DRILL TARGETS AT FLAGSHIP GRAN PILAR GOLD-SILVER PROJECT
The second reverse circulation (RC) drill rig was successfully mobilized to Tocvan Ventures Corp.'s flagship Gran Pilar gold-silver project in Sonora, Mexico, on April 6, 2026. The addition of the second rig accelerates the company's fully financed 20,000-metre drill program, enabling parallel testing of multiple high-priority targets.
Latest drill targets and program acceleration
Five key target areas in South block exist with exploration continuing:
- South block new gold-silver zone -- located 1,600 metres northeast of the Main zone, where the first aggressive stepout hole (JES-26-135) recently intersected 22.9 metres of 0.6 gram per tonne gold (including 6.1 m of 1.6 g/t Au and 13 g/t silver) from surface within a 1,200-metre-long magnetic anomaly surrounded by strongly anomalous gold-in-soil and rock samples (April 1, 2026, news release):
- El Mezquite target -- a 350-metre-long soil anomaly with rock samples returning up to 2.7 g/t Au and 24 g/t Ag, aligned with a prominent north-south magnetic linear feature interpreted as a controlling fault structure; a drill rig is currently following up on the target;
- Central target -- 500-metre-long soil anomaly with rock samples up to 5.5 g/t Au and 80 g/t Ag;
- East placer source -- anomalous soils (greater than 50 parts per billion) and rock samples (3.1 g/t Au and 18 g/t Ag); at upper source for eastern placer workings; four exploration holes completed, results pending;
- Northwest soil anomaly -- 900-metre-long soil anomaly (greater than 100 ppb, up to 21.2 g/t Au and greater than 2,000 g/t Ag); runs parallel to main placer trend;
- Central magnetic high -- 800-metre-long zone of elevated gold in soil (up to 790 ppb Au) and rocks (up to 7.3 g/t Au and 177 g/t Ag); open to the south, sampling limited;
- North extensions -- continuation of mineralized corridors north of historic drilling, includes the 2025 drilling on 100-per-cent-controlled ground that returned 3.1 metres of 19.4 g/t Au, within 106.6 metres of 0.6 g/t Au (Feb. 25, 2025, news release) and 6.1 metres of 5.4 g/t Au, within 41.2 metres of 1.0 g/t Au (May 7, 2025, news release).
"With the successful discovery of a new gold-silver zone in the South block and the continued exploration following-up on encouraging surface results, the mobilization of the second RC rig positions us to rapidly scale our exploration efforts," stated Brodie Sutherland, chief executive officer. "We are now able to drill high-priority targets in parallel, significantly accelerating our 20,000-metre program. This will not only derisk and expand the mineralized footprint but also generate critical data to support our near-term pilot mine facility and maiden resource estimate. Momentum at Gran Pilar continues to build, and we are excited to deliver further results in the coming weeks."
The second rig, mobilized on April 6, is now fully operational and will immediately double the company's monthly metreage capacity, allowing for concurrent resource expansion, infill and new target testing.

Quality assurance/quality control
Rock and drill samples were shipped for sample preparation to ALS Ltd. 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. 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.

The ALS Hermosillo and North Vancouver facilities are ISO 9001 and ISO/IEC 17025 certified. Gold and multielement analysis of soils was completed by aqua regia digestion and ICP-MS finish using a 50-gram nominal weight. Overlimit gold values greater than one g/t were reassayed with a more robust aqua regia digestion and ICP-MS 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 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.
