Calgary, Alberta – May 14, 2024 – Tocvan Ventures Corp. (the "Company") (CSE: TOC; OTCQB: TCVNF; FSE: TV3), is pleased to announce first drill results from its 2024 Reverse Circulation (RC) drill program at its road accessible Pilar Gold-Silver project in mine-friendly Sonora, Mexico. A total of 1,825.4 meters has been drilled to date in 15 drillholes.


Results today are highlighted by drillhole JES-24-77 which returned 56.4 meters of 1.0 g/t Au from 18.3 meters vertical depth, including 9.2 meters of 5.3 g/t Au. The entire length of the hole returned anomalous gold values averaging 76.3 meters of 0.8 g/t Au. A high-grade center to the mineralized zone returned 5.3 g/t Au and 3 g/t Ag over 9.2 meters, including 1.5 meters of 26.7 g/t Au. Like the Main Zone, the 4-T trend is exposed at surface along a rounded ridge top, allowing the potential for a low strip ratio during early development. The hole tested near-surface mineralization and was stopped at 76.3 meters, mineralization at 4-T remains open at depth.


Results for eleven drill holes are currently pending analysis, including holes further northwest, along the 4-T trend.


"We are extremely excited with the results today highlighting the additional resource potential that exists along the several parallel trends to the Main Zone which we believe can be tied together into a sizable area." commented Brodie Sutherland, CEO. "Today's results are the best from the 4-T Trend to date and rank as a top five drill intersect in Tocvan's history of drilling at Pilar. Gold mineralization intersected in hole JES-24-77 is close to surface, projecting to workings exposed along a low rolling ridgeline much like the Main Zone. This allows for low-strip ratio potential in future mine development, reducing costs for extraction. We are confident the 4-T Trend will continue to develop into another key resource area for Pilar, being just 400 meters from the heart of our Main Zone. Part of our bulk sample was extracted from 4-T adding to that confidence of resource viability. More results from the trend are pending. As for our exploration drill targets, it is still early in testing these areas and the data available suggests more work is needed to fully evaluate and target mineralization. Surface mapping and geochemistry strongly suggests the known trends extend to the southeast and northwest, while new trends have yet to be tested. Recent sampling across the expansion area supports this thesis, indicating much more is to be uncovered."



In addition, three exploration holes on the southeastern flanks of known mineralization (JES-24-74, 75 and 76) are also included in this release, testing known areas of significant surface mineralization. Although anomalous intervals were encountered, no significant mineralization has been recorded yet.


Discussion of Results


JES-24-77


The drillhole targeted near surface mineralization vertically below the Four Trench (4-T) prospect. The Prospect gets its name from four trenches completed historically across a known area of artisanal underground workings. The prospect was first drilled in 1996 by Santa Catalina, a Lundin Company evaluating Pilar. First drilling hit 7.5 meters of 3.3 g/t Au and 31 g/t Ag in drillhole K-16 (hole was stopped at 7.5m). Follow-up drilling over 15 years later by a private operator returned 30.5 meters of 0.7 g/t Au (JESP-18). In 2021, Tocvan drilled 15.3 meters of 1.1 g/t Au along the same ridgeline 300 meters to the northwest. The result released today from JES-24-77 is the most significant result along the 4-T trend drilled to date and ranks as the fifth best drill result ever from the over 60 drillholes Tocvan has completed thus far at Pilar. JES-24-77 was a vertical drillhole testing the down-dip projection of surface mineralization, successfully intersecting several zones of low-grade gold and silver and one high-grade zone. Follow-up work is to be completed along this developing trend.


Exploration Drill Results


Drillholes JES-24-74 and 75 tested an area southeast of the Main Zone where local surface mineralization hosted along structures and veins had returned 5.1 g/t Au and 24 g/t Ag. Although no significant mineralization was recorded in these holes, anomalous values of silver warrant further investigation. Drillhole JES-24-76 tested the southernmost flank of the 4-T trend, alteration and veining was recorded in logging although no significant mineralization was recorded.



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 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. 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.
