Tocvan Announces Discovery of New Target with Historic Underground Workings in North Alteration Zone at Gran Pilar Gold-Silver Project

CALGARY, AB / ACCESS Newswire / October 9, 2025 / Tocvan Ventures Corp. ("Tocvan" or the "Company") (CSE:TOC)(OTCQB:TCVNF)(WKN:TV3/A2PE64), a leading exploration and near-term producer focused on gold and silver projects in Sonora, Mexico, is excited to report the discovery of a new mineralized zone featuring historic underground workings within the expansive North Alteration Zone at its flagship Gran Pilar Gold-Silver Project in Sonora, Mexico. This finding expands the known mineralized footprint and highlights significant potential for high-grade gold and silver resources.

Highlights:

• New Target Identified in the middle of the North Alteration Zone, a 3.2-kilometer-long zone of extensive alteration

• 80-meter exposed section of historic underground workings and waste piles of silicified vein breccia material. Intense phyllic and argillic alteration.

• Channel and grab samples collected, results pending.

• 800-meters southwest from permitted drill target (3.2 g/t Au and 1,225 g/t Ag)

• 1,100-meters northeast from permitted drill target (2-meter chip sample of 5.6 g/t Au and 106 g/t Ag)

The newly identified zone, delineated through recent surface mapping and rock-chip sampling trends northwest and aligns with alteration patterns observed across the 3.2 km by 1.5 km North Alteration Zone. Historic underground workings, including adits and shafts dating back decades, confirm early mining activity and provide direct evidence of vein breccia hosted mineralization. Within the North Alteration Zone. Initial sampling from exposed outcrops in the area returned encouraging results, including peak values of up to 5.6 g/t Au and 106 g/t Ag over 2 meters, with broader intervals showing consistent anomalous gold and silver.

"This discovery marks a pivotal step in unlocking the full potential of the North Alteration Zone, which remains largely undrilled and underexplored," said Brodie Sutherland, CEO of Tocvan Ventures. "The presence of historic workings in this 2-kilometer corridor underscores the area's prospectivity and ties directly into our ongoing expansion strategy. We're prioritizing drill targets here to chase high-grade extensions and build on our recent success across Gran Pilar."
