Tocvan Accelerates Gran Pilar: 5,000+ Meters Drilled to Date, Historic Workings Discovered ON South Block, Pilot Progresses
TOCVAN ACCELERATES GRAN PILAR: 5,000+ METERS DRILLED TO
DATE, HISTORIC WORKINGS DISCOVERED ON SOUTH BLOCK, PILOT
PROGRESSES
Hermosillo, Mexico – May 11, 2026 – Tocvan Ventures Corp. (the “Company” or “Tocvan”) (CSE: TOC) (OTCQB:
TCVNF) (WKN: TV3/ A2PE64) is pleased to provide an update on its fully funded 20,000-meter drill program and
ongoing exploration activities at its flagship Gran Pilar Gold-Silver Project in Sonora, Mexico. The Company has
drilled over 5,300 meters to date, with results pending from twenty-one drill holes totaling over 4, 400 meters,
including three drill holes following up on the El Mezquite discovery pad . The Company is also pleased to
announce the signing of a long-term community agreement, granting surface access and permission to
conduct all exploration and pilot -production across the area. In addition, Surface exploration activities have
been focused on South Block mineralization extension , successfully identifying more historic underground
mine workings. with over 400 rock and soil samples collected to date, results are pending.
To date, over 5,300 meters have been drilled across high-priority targets as part of the accelerated program.
The Company is currently replacing one Reverse Circulation (RC) drill rig with a diamond core drill rig to deliver
higher-quality geological data and structural in formation from key targets , like the newly discovered El
Mezquite target . Tocvan is also actively looking to add a third drill rig over the next month; however, drill
availability remains limited in Sonora , the Company continues to work with its contractors to expedite the
planned drill program. Drilling continues to build on recent successes while surface exploration on the South
Block advances rapidly.
Exploration efforts on the South Block remain a key focus, with field teams continuing to identify and map
historic underground workings along the El Mezquite trend. These historic features are associated with strong
indications of mineralization, further supporting the potential for expanded gold-silver systems in this
previously underexplored corridor located approximately 1,600 meters northeast of the Main Zone.
In addition, Tocvan has successfully signed a long- term community agreement with local stakeholders that
provides a framework for continued exploration activities and development of the pilot mine facility. The
agreement ensures ongoing community engagement, benefits, and support for the project, strengthening
Tocvan’s social license to operate in the region.

Further advancing toward production, the Company has already ordered the processing plant equipment
required for the fully permitted 50,000-tonne pilot mine facility. This secures a key component and marks a
significant step in preparing for initial 50,000 tonne sample processing and pilot-scale gold-silver
production at Gran Pilar.
“Drilling is progressing efficiently and we are very encouraged by the continued positive developments
on the South Block,” commented Brodie Sutherland, CEO of Tocvan. “The identification of historic
underground workings and associated mineralization along the El Mezquite trend highlights the scale and
prospectivity of this new growth corridor. The signing of the long -term community agreement together
with the already ordered processing plant are major milestones that solidify our community partnerships
and position us for near-term pilot production. Replacing one RC rig with a core rig will provide us with
even better geological information, we are working with local contractors to secure a third rig to maintain
strong momentum.”
The Company will continue to provide regular updates as drilling and exploration results become available.

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.
