Calgary, Alberta – September 10, 2024 – Tocvan Ventures Corp. (the “Company”) (CSE: TOC; OTCQB: TCVNF; FSE: TV3), is
pleased to provide an update from its Gran Pilar gold-silver project in mine-friendly Sonora, Mexico. Surface soil and rock
sampling has been ongoing across the Gran Pilar project area with a focus on the northern and eastern extensions of the
Main Zone, North Hill and 4-T trends. To date, over 476 surface samples have been collected by technical staff with results
pending. The area sampled now totals over 230 hectares or 2.3 square kilometers across the southern block of Gran Pilar
(Figure 1).

“We are pleased with how quickly our area of interest is expanding and the added confidence we are gaining with each
progression of Gran Pilar” commented Brodie Sutherland, CEO. “Gran Pilar is largely untapped for resource potential and
the work being completed is strengthening our position as a leading explorer and developer in Sonora. As we await the
latest results, we can already see the significance of these new areas and the positive impact they have for us moving
forward. As discussions continue with potential strategic partners, our conviction to transform Gran Pilar into a top tier
asset has never been stronger. We look forward to updating our shareholders throughout this transformation.”
During sampling multiple underground artisanal workings were identified that coincide with prospective host rocks and
mineralization similar to those recorded at the Main Zone. A soil grid across the area, spanning 675-meters north of the
Main Zone and over 2-kilometers east, is now complete and will provide data to finalize the alteration and mineralization
modelling for advanced drill targeting of the new area (blue hatched area in Figure 1). Metal distribution and alteration
modelling was completed by an independent professional, Guillermo Turner Saad and utilizes over 1,300 rock and soil
samples. Pending results from the ongoing surface evaluation work will be incorporated in ongoing model development.
The modelling will provide key information for defining target areas for future drilling campaigns and outlining areas
appropriate for future mine-infrastructure.
In addition, preliminary alteration modelling across Gran Pilar’s southern area has been completed. Key alteration trends
modelled from rock and soil geochemistry has begun to outline target areas across Gran Pilar with argillic to advance argillic
alteration patterns indicative of robust epithermal mineralized systems. Areas of Interest east of the Main Zone are
showing large footprints of alteration that coincide with early reconnaissance sampling completed earlier this year (See
Figures 1 and 3). Initial surface results released early this year that identified several high-grade gold and silver zones east
of the Main Zone highlighted by 7.3 g/t Au with 177 g/t Ag and 5.5 g/t Au with 80 g/t Ag (see Figure 1 and April 18, 2024
news release) and the ongoing work of small, placer miners in the area which continue to report positive results from
several areas of interest. The modelling is showing a significant increase in the broader target potential.
Drill Update
As surface work continues through the rain season in Sonora, preparations continue for the next phases of core and RC
drilling that will focus on resource definition. Between 1,200 to 2,000 meters of core drilling are being considered along
with 1,700 to 2,500 meters of RC drilling before the end of the year. Additional drilling of exploration targets across Gran
Pilar will be considered later in the year. Core drilling will focus on building a robust geological model across Pilar with
emphasis on the Main Zone. RC drilling will concentrate on additional infill and step -out targeting across the Main Zone,
North Hill and 4-T trends. Upon completion of drilling the Company anticipates a maiden resource estimate will be finalized
for the initial Main Zone and adjacent trends providing an initial step of showcasing the full potential of the project area.
With plenty of follow -on work to complete in the field before the commencement of drilling, the Company is evaluating
optimal timing to start up drilling with weather expecting to stabilize in September.
A renewed drill contract with CANMEX for 3,000 to 5,000 -meters of core drilling has been executed encompassing
necessary core drilling for resource definition and beyond. This contract accompanies a previous 10,000 -meter contract
signed for RC drilling acr oss the Gran Pilar property. While monitoring weather conditions the Company is currently
finalizing plans for the next phases of drilling it expects to commence in September. In the meantime, the technical team
will focus on field exploration and target generation.
Pilot Plant Update
Planning continues for a proposed pilot plant facility at Gran Pilar that will look to evaluate 50,000 tonnes of material on -
site. The C ompany looks to utilize the at surface exposure of mineralization to further evaluate the viability of gold and
silver extraction. Permitting is expected to be complete in Q42024 with potential start of pilot mining to be initiated in
Q12025. Dialogue between the Company, permitting consultants and regulators has been positive and the Company does
not foresee any delays with permitting. The Company will target at surface material expected to average 1.3 g/t Au, and
from the 2023 bulk sample testing expects a base recovery of 62%. The Company will be looking to optimize heap leach
recovery and testing other methods, agitated leach and gravity to run comparative analysis.

About the Pilar Property
The Pilar Gold-Silver property has returned some of the regions best drill results. Coupled with encouraging gold and silver
recovery results from metallurgical test work, Pilar is primed to be a potential near-term producer. Pilar is interpreted as a
structurally controlled low -sulphidation epithermal system hosted in andesite rocks. Initially t hree primary zones of
mineralization were identified on the original property from historic surface work and drilling and are referred to as the
Main Zone, North Hill and 4 -T. Each trend remains open to the southeast and north and new parallel zones have been
discovered. Structural features and zones of mineralization within the structures follow an overall NW -SE trend of
mineralization. Mineralization extends along a 1.2 -km trend, only half of that trend has been drill tested so far. The
Company has now expanded its interest in the area by consolidating 22 square -kilometers of highly prospective ground
where it has already made significant surface discoveries.

Based on management’s strong belief in the project’s potential, the Company is outlining a permitting and operations
strategy for a pilot facility at Pilar. The facility would underpin a robust test mine scenario with aims to process up to 50,000
tonnes of material. Timelines and budget are being prepared with the aim of moving forward with the development early
in 2025. With gold prices hitting all- time highs, the Company believes the onsite test mine will provide key economic
parameters and showcase the mineral potential of the area. In 2023, the Company completed an offsite bulk sample that
produced important data showcasing the potential to recover both gold and silver through a variety of methods including
heap leach, gravity and agitated leach (see August 22, 2023 news release for more details).
