Calgary, Alberta – July 16, 2024 – Tocvan Ventures Corp. (the "Company") is pleased to announce drill results from its 2024 Reverse Circulation (RC) drill program at its road accessible Pilar Gold-Silver project in mine-friendly Sonora, Mexico.

To date, the 2024 drill program has completed 3,268 meters across 26 drill holes. Results for three drill holes are currently pending analysis (green squares on Figure 1).

"Drill results are continuing to show the broad scale of mineralization at Pilar as we push out the edges of the known deposit." commented Brodie Sutherland, CEO. "The infill drilling looks to connect each of the three known trends to date, the results tell us that mineralization does connect across these corridors. Most of the area has never seen detailed drilling and to see mineralization and alteration in all holes showcases the robust system we have. We are also seeing areas with elevated base metals indicating multiple phases of gold and silver deposition, an excellent advantage when expanding and exploring across the greater Pilar area." "The results today are supporting the case that we are just scratching the surface of the potential at Pilar. Results for exploration drilling 600 meters south of the Main Zone are still pending and surface work is ongoing. We look forward to updating our shareholders as more results become available."

Results today highlight five infill drill holes on the Main Zone, North Hill and 4-T trends with the primary objective to connect each corridor. Detailed results with pathfinder elements are summarized in Table 1.

Discussion of Results

4-T Trend
JES-24-91
JES-24-91 tested within the 4-T trend along the southwestern edge leading towards the North Hill trend. The hole was vertical, drilled to a depth of 100.7 meters. Moderate zones of mineralization were encountered with elevated zinc and arsenic indicating proximity to higher-grade mineralization. The hole returned 32.0 meters of 591 ppm zinc and 314 ppm arsenic with elevated gold and silver values. As a comparison the bulk sample completed in 2023, returned an average of 400 ppm zinc. Much of the 4-T trend has only seen wide spaced drill testing to date and remains open.

Main Zone East Infill
JES-24-92, JES-24-93 and JES-24-94
Infill holes JES 24-92 and 93 were drilled off the same pad testing the eastern flank of the Main Zone trend to see if the neighboring North Hill trend connects. JES-24-92 was drilled to the north at a 45-degree angle and to depth of 91.5 meters. JES-24-93 was a vertical hole drilled to 119.0 meters. Anomalous silver and zinc values were recorded along with alteration and veining indicative of mineralization within the Main Zone, further evaluation of the eastern flank and its relationship connecting the North Hill Trend is warranted. Infill hole JES-24-94 tested a space along the eastern edge of the Main Zone, a broad anomalous zone of mineralization was recorded along with elevated silver values. JES-24-94 was a vertical hole drilled to a depth of 170.8 meters. A 120.5-meter zone of anomalous gold, silver and zinc was recorded expanding out the eastern side of the Main Zone.

North Hill Trend
JES-24-95
Infill hole JES-24-95 tested the southern extent of the North Hill Trend. Broad anomalous mineralization was recorded with high-grade zinc intervals. The hole was vertical and drilled to a depth of 96.1 meters, with mineralization recorded over 76.3 meters starting at a depth of 1.5 meters. A 16.8-meter zone of higher-grade zinc was recorded, returning 0.2 g/t Au, 2 g/t Ag and 1.5% Zn. A deeper zone of gold mineralization returned 5.1 meters of 0.8 g/t Au. Pathfinder elements arsenic and molybdenite were also elevated across the hole. The hole is located 65-meters south-southeast of JES-22-63 which returned 67.1 meters of 0.2 g/t Au and 4 g/t Ag, including 13.7-meters of 0.6 g/t Au and 13 g/t Ag and 9.2-meters of 0.6 g/t Au, 3 g/t Ag and 0.6% Zn. JES-24-95 is also located 65-meters northwest of JES-22-72 which returned 157.1-meters of 0.1 g/t Au and 4 g/t Ag including 10.7-meters of 0.6 g/t Au, 40 g/t Ag and 1.7% Zn. This area of the trend is developing into a sizable domain with known elevated gold, silver and zinc values.

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.

Quality Assurance / Quality Control

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 part of the Company's robust quality assurance / quality control protocol.
