HERMOSILLO, MEXICO / ACCESS Newswire / April 1, 2026 / Tocvan Ventures Corp. (the "Company" or "Tocvan") (CSE:TOC)(OTCQB:TCVNF)(WKN:TV3/ A2PE64) is pleased to announce a significant new drill discovery in the South Block of its flagship Gran Pilar Gold-Silver Project in Sonora, Mexico. RC hole JES-26-135 intersected 22.9 m of 0.6 g/t Au from surface (including 6.1 m of 1.6 g/t Au and 13 g/t Ag) and 10.69 m of 0.4 g/t Au at 122.0 m depth in the first-ever aggressive step-out from the Main Zone, 1,600 meters to the northeast. The discovery occurs within the northern portion of a 1,200-meter-long magnetic anomaly that is surrounded by strongly elevated gold values in rock and soil samples. The anomaly itself hosts some of the highest-grade and highest-concentration gold anomalies identified to date on the property.

RC Drilling is ongoing as part of the Company's fully funded 20,000-meter program, with over 2,400 meters completed to date.

Highlights

• New discovery 1,600 m east of Main Zone - first aggressive step-out in South Block returns 22.9 m @ 0.6 g/t Au from surface, including 6.1 m @ 1.6 g/t Au & 13 g/t Ag (JES-26-135)

• Additional deeper zone: 10.7 m @ 0.4 g/t Au (including 3.1 m @ 1.3 g/t Au & 13 g/t Ag) from 122 m downhole

• Mineralization hosted in northern portion of 1,200 m long magnetic anomaly surrounded by strongly anomalous gold-in-soil and rock samples; 2.4 g/t Au and 21.9 g/t Ag in soils (40 m north of JES-26-135) and 2.7 g/t Au with 17 g/t Ag and 2.3 g/t Au with 24 g/t Ag in rocks (15 m south of JES-26-135)

• Part of fully funded 20,000 m program; >2,400 m completed to date

• First three exploration holes from South Block and six pilot-facility holes reported in this release

Tocvan Ventures - Significant Drill Discovery 1,600 Meters from Main Zone at Gran Pilar

Why This Discovery Matters

• Proves district-scale potential: The 1,600 m step-out is the first aggressive test beyond the Main Zone and immediately hits mineralization, significantly expanding the known footprint of the Gran Pilar system.

• Validates targeting strategy: Discovery sits inside a 1,200 m magnetic anomaly that already hosts the strongest gold-in-soil (1,200 m of >50ppb Au; incl., 260 m of 180 to 1,200 ppb Au) and rock geochemistry on the entire property, confirming that geophysics combined with surface geochemistry in conjunction with geological and structural mapping are effective tools for new discoveries.

• Opens a new mineralized corridor: The South Block now demonstrates its own independent mineralized zone at surface, separate from the Main Zone, increasing the overall size and scale potential of the project.

• De-risks future growth: Early success in the fully funded 20,000 m program shows that high-priority targets identified by magnetics and geochemistry can deliver immediate results, accelerating resource expansion and exploration momentum.

• Enhances project viability: A significantly larger mineralized system at surface supports the potential for open-pit resources, strengthening the pathway toward near-term production and long-term value creation.

"This is a landmark result for Tocvan," commented Brodie Sutherland, CEO. "For the first time we have aggressively tested well beyond the Main Zone in the South Block and immediately intersected mineralization at surface. The location within a large magnetic anomaly that already shows the strongest surface gold geochemistry on the project underscores the scale potential we see at Gran Pilar. With over 2,400 meters already drilled in our fully funded 20,000-meter program, we are well positioned to continue expanding this new discovery and testing additional high-priority targets. Currently drilling is active 300 meters east of this new discovery, testing the current eastern limit of known mineralization. Our programs are fully funded for drilling and pilot mine operation. With a clear path to near-term pilot production, these early South Block results significantly increase the scale and potential of Gran Pilar."

A total of three exploration drill holes and six holes related to the pilot facility are included in this news release. The Company will provide further updates as additional drill holes are completed and assays are received.

The majority of the project has seen no modern exploration, first pass reconnaissance drilling is being completed for the first time across the South Block.

El Mezquite Target

Initial drill target was elevated gold and silver in soils and rock samples. Up to 2.4 g/t Au and 21.9 g/t Ag in soils, within 350-meter-long soil anomaly. Rock samples including 2.7 g/t Au, 17 g/t Ag and 0.68% Pb and 2.3 g/t Au, 24 g/t Ag and 0.92% Pb. All hosted within andesite volcanic rocks, that make up the primary host across most of the project area. The target coincides with magnetic linear feature (interpreted fault structure) that extends north-south for over 1,200 meters. The target is open north and south along strike and further to the northwest towards another elevated soil sample (247 ppb Au or 0.25 g/t Au). Two zones (0.0-22.9m and 122.0-132.7m) were intersected in drillhole JES-26-135 with anomalous mineralization in between. Since the drillhole started in mineralization the full extent and potential width is unknown at this time. A drill will follow-up to further define the extent of mineralization at the target.

Pilot Drilling

The Company is also pleased to announce successful completion of drilling in preparation for the Pilot Mine Facility. A total of four condemnation holes were completed underneath the future mine facility and infrastructure. No significant mineralization was intersected, confirming the area is suitable for long-term infrastructure. A total of two water monitoring wells were drilled. The upper well, closest to existing drilling was sampled and returned anomalous gold and silver (up to 0.13 g/t Au and 22.6 g/t Ag), which likely represents the outer extent of mineralization extending from the North Hill prospect 100 meters to the southeast.

Summary of Other Exploration Drilling

JES-26-133 tested the southern extension of the same magnetic feature and intersected seven anomalous zones with up to 0.3 g/t Au and 21.5 g/t Ag; the hole ended in mineralization.

JES-26-140 tested a southern target and returned 13.7 m of anomalous mineralization with up to 0.2 g/t Au, 17 g/t Ag and elevated pathfinder elements.

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 analyzed 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
