Tocvan drills 106.8 m of 0.5 g/t Au at El Mezquite

130m North of Discovery Hole That Returned 215m of 0.6 g/t Au

HERMOSILLO, MX / ACCESS Newswire / September 23, 2026 / Tocvan Ventures Corp. (the "Company" or "Tocvan") (CSE:TOC)(OTCQB:TCVNF)(WKN:TV3/A2PE64) is pleased to announce new drill results from the El Mezquite trend at its 100%-owned Gran Pilar Gold-Silver Project in Sonora, Mexico.

Hole JES-26-175, collared approximately 130 metres north of discovery hole JES-26-155 (215m of 0.6 g/t Au), returned a broad, near-surface gold-silver interval of 106.8 metres grading 0.50 g/t Au and 3.5 g/t Ag within a much larger envelope of 271.5 metres grading 0.3 g/t Au and 2.4 g/t Ag from 1.5 metres downhole. Internal higher-grade zones include 16.8 m of 1.0 g/t Au and 3.1 m of 1.1 g/t Au and 23.4 g/t Ag.

The result extends continuous mineralization north of the August 6, 2026 discovery hole (JES-26-155: 215.0 m of 0.6 g/t Au from 36.6 m) and builds on the September 16 confirmation hole JES-26-172 (81.1 m of 0.5 g/t Au from 13.5 m, including 47.7 m of 0.8 g/t Au and 2.8 m of 8.4 g/t Au and 54 g/t Ag). El Mezquite is now traced over approximately 1,400 metres and sits 1.6-1.9 km east of the Main Zone and the permitted 50,000-tonne heap-leach pilot facility, with existing road access.

Hole JES-26-175 is the third major intercept along the El Mezquite corridor, after discovery hole JES-26-155 and confirmation hole JES-26-172.

CEO, Chris Gordon commented: "Three significant holes now define El Mezquite: 215 metres of 0.6 g/t gold in the discovery hole, 81 metres starting near surface with a high-grade core of 8.4 g/t gold in the confirmation hole, and now 107 metres of 0.5 g/t gold inside a 271-metre envelope 130 metres further north. That last hole is very significant. In Sonora, heap-leach cut-offs are typically around 0.10 to 0.15 g/t gold, and operating mine grades are often in the 0.25 to 0.40 g/t range. We are seeing 0.5 g/t over more than 100 metr
