Tocvan Announces New Surface GOLD-Silver Results, Outlining New Target 3 Kilometers East of Main Zone at Gran Pilar GOLD-Silver Project
TOCVAN ANNOUNCES NEW SURFACE GOLD-SILVER RESULTS,
OUTLINING NEW TARGET 3 KILOMETERS EAST OF MAIN ZONE AT
GRAN PILAR GOLD-SILVER PROJECT
Hermosillo, Mexico – May 13, 2026 – Tocvan Ventures Corp. (the “Company” or “Tocvan”) (CSE: TOC) (OTCQB:
TCVNF) (WKN: TV3/ A2PE64) is pleased to announce new surface exploration results from the recently identified
Bojorquez Target at its flagship Gran Pilar Gold-Silver Project in Sonora, Mexico. The Bojorquez Target is located
approximately 3 kilometers east of the Main Zone.
Rock chip sampling at Bojorquez has returned significant gold and silver values, highlighted by assays up to
1.5 g/t Au and 39 g/t Ag. Multi -element results also show strongly anomalous base -metal and pathfinder
values, including copper up to 0.37% Cu, lead up to 0.89% Pb, zinc up to 0.33% Zn, arsenic up to 4,730 ppm As,
and antimony up to 422 ppm Sb . Along the western edge of the target a silver -arsenic anomaly trend along
a northwest magnetic high. Highlights from the initial 79 rock samples are summarized in table 1.
These mineralized samples coincide with prominent magnetic anomalies identified in recent drone
geophysical surveys, indicating potential for structurally controlled epithermal gold -silver mineralization
analogous to the Main Zone. The anomalous zone defined by sampling to date measures approximately 1,200
meters by 700 meters, outlining a sizable new target area for immediate follow -up exploration.
“The discovery of the Bojorquez Target further demonstrates the district -scale potential of Gran Pilar,”
commented Brodie Sutherland, CEO of Tocvan. “Surface gold and silver values coincident with magnetic
anomalies 3 km east of the Main Zone are extremely encouraging. This new target adds significant upside
to our ongoing drill and development programs, and we are eager to advance it with detailed mappi ng,
expanded geochemistry, and drilling.”
The Company is currently prioritizing follow- up work within the South Block, including additional surface
sampling, detailed structural mapping, and integration of geophysical data to refine drill targets. Results for
over 300 surface samples are pending with active surface exploration ongoing in the South Block.

KEY GEOLOGICAL INSIGHTS
Au Mineralization:
• Quartz veins with intense hematite show highest Au grades (avg ~0.5 g/t, max 1.52 g/t)
• Silicification (intense) correlates with elevated Au values
• Samples with jarosite in boxwork texture show good Au potential
Ag Mineralization:
• Quartz-tourmaline massive veins show exceptional Ag (up to 36.5 g/t)
• Samples with chrysocolla traces show elevated Ag values
• Diorite/quartz diorite dikes with propylitic alteration carry moderate Ag

Quality Assurance / Quality Control
Rock and Drill samples were shipped for sample preparation to ALS Limited 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 analyz ed using 50-gram nominal weight fire assay with atomic absorption spectroscopy finish. Over
limits for gold (>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. Over limit analyses for silver (>100 g/t) were re-assayed 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.
