Results Pending for Three Additional Holes
CALGARY, AB / ACCESS Newswire / March 26, 2025 / Tocvan Ventures Corp. (the "Company") (CSE:TOC)(OTCQB:TCVNF)(WKN:TV3/A2PE64), is pleased to announce results from the latest core drilling at the Gran Pilar Gold Silver Project in mine-friendly Sonora, Mexico. Ten core drillholes totalling 1,167.5 meters were completed earlier this year within the majority owned (51%) Main Zone held in partnership with Colibri Resource Corp. Today's results are highlighted by 21.6 g/t Au, 209 g/t Ag and 6.7% Pb over 3.0 meters, also 2.8 g/t Au, 38 g/t Ag and 2.3% Zn over 3.8 meters within a broader anomalous zone averaging 1.2 g/t Au starting from surface to a vertical depth of 64.9 meters (JES-25-108). The significance of this hole is its location 300 meters east of the Main Zone Trend in line with the North Hill Trend, making it the first discovery of high-grade gold mineralization along the southern end of this corridor. The high-grade looks to be hosted within a highly fractured near-surface fault zone with associated quartz veining. Given the proximity to surface this area will be selected for future trenching to further evaluate the extent of high-grade mineralization for potential pilot mine feed. In addition, hole JES-25-107, 100 meters east of the Main Zone has returned the best values to date on the eastern flank of the Main Zone. The hole returned 108.2 meters of 0.2 g/t Au and 5 g/t Ag from surface, including 12.6 meters of 0.9 g/t Au, 20 g/t Ag and 0.5% Cu; 7.4 meters of 0.5 g/t Au and 8 g/t Ag; and 4.3 meters of 0.6 g/t Au and 7 g/t Ag. Mineralization is hosted within a silicified brecciated andesite with coarse veins of pyrite and chalcopyrite. Hole JES-25-109 only returned a few isolated zones mineralization, core logging shows the hole intersected a large fault zone that separates mineralization hit in past drilling (JES-22-53, and JES-24-79). Results for seven core drillholes have now been released, results are pending for the remaining three holes which have tested the outer extents on mineralization.
"Core drilling has just returned the highest-grade interval ever outside of the Main Zone, located 300 meters away on an emerging trend." commented, CEO Brodie Sutherland. "The best part is that it is only meters below the surface allowing us to easily access the area with trenching we have planned in the next phase of exploration. This provides us with another area to source mineralization for potential pilot mine material. Trends like the North Hill remain largely untested and suggest other areas across the broader expansion area hold significant potential for hosting high-grade gold and silver. We look forward to continued drilling across the expansion area to begin targeting additional resource potential."

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).

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 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.
