Tocvan News Release:

(April 3, 2024) - Brodie A. Sutherland, P.Geo. reports:

Tocvan Ventures Corp. (the "

Company

"), is pleased to announce the much awaited restart of drilling at

its road accessible Pilar gold-silver project in the mine-friendly State of Sonora, Mexico. The Company

has been busy reviewing all past data with an independent resource professional to determine the most

effective use of drill meters for the upcoming campaign. Work completed has outlined 7,000 meters of

drilling required within the Pilar concessions held along with minority partner, Colibri Resources. This

includes, 4,000 meters of infill drilling within known areas of mineralization and 3,000 meters of step-out

and exploration drilling on the peripherals of drilled mineralization and/or strong surface geochemistry

indicating highly prospective targets. All proposed drilling is fully permitted. The outcome of the

proposed drilling will go into the definition of a maiden resource estimate for the Pilar Main Zone,

providing an important building block for the Company. The first drill hole will follow-up on JES-22-62,

which returned

108.6m of 0.8 g/t Au and 3 g/t Ag.

The drill rig mobilized to site April 1

st

and began

drilling hole JES-24-73 on April 2

nd

. The Company will update as drilling progresses.

"We are excited to report the drill is back onsite and turning at Pilar," commented Brodie

Sutherland, CEO. "It's been nearly two years since we last drilled at Pilar, with the previous drill

program identifying new areas of mineralization to the east and southeast of Pilar's Main Zone.

We now look to continue to expand the overall footprint while we build towards a maiden

resource at Pilar. With gold prices hitting all time highs, we feel this is the right time to

aggressively advance our projects."

About the Pilar Property

The Pilar Gold-Silver property has returned some of the region's 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 three 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.
