Tocvan Outlines High-Grade Gold Results for Start of Diagnostic Leach Study; Stockpile of Bulk Sample Complete
Tocvan Ventures Corp. has reported progress at its Pilar Gold-Silver Project in Sonora, Mexico, with over 1,200 tonnes of material stockpiled for bulk sampling. Diagnostic leach tests returned high-grade results averaging 6.2 g/t Au to 11.1 g/t Au across samples. The company has identified coarse free gold in screened materials and added a gravity recovery circuit for testing. A $600,000 CAD private placement with an institutional investor is underway, comprising 1,102,941 units at $0.544 each. Funds will support drilling and operational programs. Further updates are anticipated in April.

CALGARY, AB / ACCESSWIRE / March 29, 2023 / Tocvan Ventures Corp. (the "Company") (CSE:TOC)(OTCQB:TCVNF)(FSE:TV3), is pleased to provide a progress update on its first bulk sample at the Pilar Gold-Silver Project in Sonora, Mexico. Over 1,200 tonnes of material have been stockpiled, with first shipments of material completed. Crushing, screening circuit and laboratory setup is completed. Material crushing and screening has started. Foundation and drainage system for leach pad installation is ongoing. Separate to the Bulk Sample, head-grade results from the precious metal diagnostic leach tests have returned high-grade results with the five samples averaging 6.2 g/t Au, 7.6 g/t Au, 1.3 g/t Au, 11.1 g/t Au and 7.6 g/t Au respectively (see Table 1). Diagnostic leach tests are ongoing and were collected from four trench areas and one select drill core coarse reject sample. Preliminary results from the study suggest free gold is present in the samples and has been confirmed visually by testing sieved (<3/8") material. A gravity concentrator unit will be utilized to conduct formal testing for the presence and abundance of free gold in the finer grained fraction. At Pilar, trenching related to the bulk sample has unearthed several buried underground working entrances along quartz vein structures, another indicator of the robust mineralized system and a useful tool for mapping new high-grade structures.

"We are extremely pleased with the bulk sample progress so far and how quickly we are learning more about the robust mineralized system at Pilar," stated Brodie Sutherland, CEO. "All the material we need for the sample is now stockpiled. Through trenching and excavation for the sample we have unearthed historic workings that clearly were focused on higher-grade mineralization, this will provide us with key information to aid in future targeting. The new exposures are also giving us excellent structural data to enhance our modelling. We are also seeing free gold visible in the finer fraction of sample material which we will evaluate further. In addition, the first results highlighting the head-grade for samples collected for diagnostic leach have returned very encouraging results. We look forward to updating shareholders as we progress."
About the Bulk Sample
Up to 1,000 tonnes of oxide-gold material will be extracted from select areas exposed at surface across the project area, focusing on the Main Zone and 4-T Trends where preliminary column leach studies have returned promising head-grade and recovery results. Bulk Sample material will be extracted and prepared for processing by heap-leach method at a private mining operation less than 25 kilometers to the west of Pilar. Information from the sample will aim to provide a more detailed account of expected head-grade and recovery percentage of gold along with providing key information to optimize future production facilities. The information provided from the sample will be used for planning in coordination for permitting of full-scale mine and process facilities on-site at Pilar.
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.

About the El Picacho Property
The El Picacho Gold-Silver property is interpreted as an orogenic gold system within the regional Caborca Orogenic Gold Belt known for producing gold mines that include La Herradura (>10 Moz Au) and San Francisco (>3 Moz Au). The project is 140 kilometers north of Hermosillo and only 18 kilometers southwest of the producing San Francisco Mine. The Project totals 24 square kilometers of area showing similarities in geology and structure as the San Francisco Mine. Five primary zones of mineralization have been identified across the property totalling over six kilometers of prospective trends. Surface sampling and historic workings have identified high-grade gold and silver values. Recently the Company completed its first drill program at El Picacho, confirming its model and hitting significant gold mineralization In a step-out to historic workings. Drill hole SRA-22-010, intersected 44.2-meters of 0.6 g/t Au, including 12.2-meters of 2.0 g/t Au and 7 g/t Ag. As exploration and drilling continues, Tocvan believes this provide an excellent opportunity for discovery of a muti-million ounce district.
