CALGARY, AB / ACCESSWIRE / May 16, 2023 / Tocvan Ventures Corp. (the "Company") (CSE:TOC)(OTCQB:TCVNF)(FSE:TV3), is pleased to provide an update and sampling results from a Bulk Sample being completed at its Pilar gold-silver project in Sonora, Mexico. Sampling of duplicate material collected at regular intervals during crushing/screening process from the Bulk Sample have returned consistent gold and silver values. In total, 148 samples were collected averaging 1.87 g/t Au and 13 g/t Ag (see Table 1 for full results). The first batch of 32 samples (111 samples pending) were collected from the fine fraction of screened material not included in the heap leach pile, are showing slightly higher grades of gold and silver, averaging 2.02 g/t Au and 15.6 g/t Ag (see Table 2 for full results). The fine fraction along with additional bulk sample material will be used in testing gravity recovery methods. Samples were submitted to ALS Hermosillo for fire assay and ICP analysis. Blanks and standards were submitted into the sample stream as part of the Company's robust QA/QC protocol The samples total 910.7 kg of crush reject material from the Bulk Sample collected for heap leach testing. The heap leach process is currently underway for the Bulk Sample. Over 800 tonnes of Bulk Sample material have been prepared for heap leach processing, an additional 350 tonnes of crushed material and 250 tonnes of raw-bulk sample are available for gravity recovery and later agitated leach testing as recommended by an independent report provided by LTM.
"Pilar continues to surprise with excellent gold and silver values." stated Brodie Sutherland, CEO. "The results are clearly indicating the average grade of material making up the Bulk Sample are well above our expectations for gold and silver. To see this represented in the data gives us added confidence that Pilar can be advanced towards production, especially with these impressive grades. We eagerly await the results from heap leaching and further evaluation of gravity recovery methods."

About the Pilar Property
The Pilar Gold-Silver property has recently 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. Three primary zones of mineralization have been identified in the north-west part of the property from historic surface work and drilling and are referred to as the Main Zone, North Hill and 4-T. The Main Zone and 4-T trends are open to the southeast and new parallel zones have been recently 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. To date, over 23,000 m of drilling has been completed.

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. Silver and other elements were analyzed using a four-acid digestion with an ICP 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.
