Video: Soil Sample Overview
CALGARY, AB / ACCESSWIRE / November 12, 2024 / Tocvan Ventures Corp. (the "Company") (CSE:TOC)(OTCQB:TCVNF)(FSE:TV3), is pleased to provide exploration results 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 541 soil samples and 184 rock chip samples and counting have been collected by technical staff. Results for 541 soil samples are provided in this release across an area that totals over two-square kilometers within the southern block of Gran Pilar where Tocvan holds 100% interest (see Figure 1). This data builds off of a previous soil grid completed across the original Pilar concessions. The soil grid was completed along north-south orientated lines 100 meters apart with 50-meter sample spacing. Soil material from each site was sieved below 200 mesh or 74 microns, collecting an average sample size of 1.3 kg at each sample location. The southern block remains unsampled 1.4 kilometers east and 400 meters south of the soil grid released today. Another four-square kilometer remains unsampled and open for additional discovery within the southern block alone.
In exploration, soil sampling is a useful tool for locating areas of interest through the geochemical expression of weathered rock. The subtle increase in gold or other pathfinder elements are tracked to outline target areas. Samples returning values greater than 0.02 g/t Au or 20 ppb Au are thought to be anomalous and worthy of closer evaluation. Sample results with values greater than 0.1 g/t Au or 100 ppb Au are thought to be significant and warrant immediate follow-up as near surface mineralization is likely. It is important to note that the soil samples are widely spaced on a 50-meter by 100-meter grid. The results have yielded high-grade gold and silver mineralization across the sample grid with the highest value returning 21.2 g/t Au (21,200 ppb), greater than 2,000 g/t Ag, 0.62% Cu, 12.7% Pb and 2.3% Zn. Follow-up has shown this highly anomalous sample coincides with a nearby historic working concealed in overgrown vegetation. This sample is within a broader zone of anomalous values that extends for over 800-meters long and 500-meters wide. Several other zones of significant and consistently high values of gold have been identified showing several kilometers of prospective trend that remains open to the east for further expansion.
For reference, historically the highest soil sample across the Main Zone returned 8.1 g/t Au and 12 g/t Ag with most values ranging as low as 0.04 g/t Au or 40 ppb Au. Results from the recent soil survey are summarized in Figure 1 and Table 1.
"The results from the soil survey are simply incredible with samples exceeding the analysis overlimits two to three times; outlining the much larger potential for significant mineralization at Gran Pilar" commented Brodie Sutherland, CEO. "The consistently high values across the area is telling of the overall potential, this area also coincides with early reconnaissance sampling that has returned significant gold and silver values released earlier this year. It is fantastic to see several values in excess of 1 gram per tonne in the soil results and immediate follow-up has proven the values are directly related to mineralized structures tied to historic workings. This proves the soil sampling method is extremely effective in discovering new areas of interest. As surface work and drill preparation continues, we look forward to refining these targets for future drill programs. It is important to note that the entire area has never seen systematic and modern exploration, these areas are completely new and we are beginning to outline the larger mineralized system that remains untested. This is just one portion of the southern block of Gran Pilar with even larger untested sections of the property extending to the north. More results are to come as we unlock the full potential of Gran Pilar."

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.

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
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 and multi-element analysis of soils was completed by aqua regia digestion and ICP-MS finish using a 50-gram nominal weight. Over limit gold values greater than 1 g/t were re-assayed with a more robust aqua regia digestion ad ICP-MS 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 blank samples and certified reference materials were systematically inserted into the sample stream and analyzed as part of the Company's robust quality assurance / quality control protocol.
