Tocvan Releases El Picacho Surface Results Identifying Undrilled Au-Ag Target Zone Over 450-meter Trend Highlighted By: 7.2 g/t Au and 36 g/t Ag; 4.5 g/t Au and 197 g/t Ag; and 3.3 g/t Au and 67 g/t Ag.
Calgary, Alberta – TheNewswire - July 6, 2022 Tocvan Ventures Corp. (the “Company”) (CSE:TOC); (OTC:TCVNF); (FSE:TV3), is pleased to announce surface sample results from its El Picacho Au-Ag Project in Sonora, Mexico. A surface exploration program has been ongoing since April. At the Murcielago Prospect, a total of 65 samples were collected with 14 samples returning values greater than 0.1 g/t Au (Table 1). Sampling defined a new target area yet to be drilled. The Murcielago Prospect has been confirmed and expanded with Au-Ag values (7.2 g/t Au and 36 g/t Ag) hosted within a brecciated dolomitic limestone unit along a 450-meter west-southwest trend. Significant lead and zinc mineralization is noted to occur along with gold and silver within the prospect area (4.5 g/t Au, 197 g/t Ag, 4.8% Pb and 7.1% Zn). Murcielago Prospect is the only mineral occurrence on the El Picacho property identified to date hosted within Jurassic aged sedimentary rocks. Historic artisanal workings are present following high-grade mineralization from surface in shafts (Plate 1).
450-meter trend of gold-silver hosted in a brecciated dolomitic limestone, highlighted by:
7.2 g/t Au, 36 g/t Ag and 4.4% Pb
4.5 g/t Au, 197 g/t Ag, 4.8% Pb and 7.1% Zn
3.3 g/t Au, 67 g/t Ag and 1.6% Pb
2.7 g/t Au, 25 g/t Ag and 1.9% Zn
Historic Murcielago Results, highlighted by:
15.1 g/t Au, 18 g/t Ag and 2.9% Pb
13.8 g/t Au, 83 g/t Ag and 1.7% Pb
8.8 g/t Au, 234 g/t Ag and 4.6% Pb
“The results from our recent surface exploration program have confirmed another untested drill target at El Picacho.”, commented CEO, Brodie Sutherland. “The Murcielago Prospect is one of six key target areas at El Picacho that has seen little to no drilling. The consistent mineralization seen across a 450-meter trend coupled with high-grade historic results along old shafts, makes Murcielago an additional compelling drill target as we look to unlock the potential of the project. Sonora is well known for cost-effective mines that can operate open pits with grades below 0.5 g/t Au with very favourable production costs. Seeing this broad low-grade mineralization and higher-grade within gives us a lot of confidence in the potential we have here.”
Update on Pilar Drill Program
As part of the ongoing Phase III drill program, a total of four reverse circulation (“RC”) drill holes have been completed since the program restarted on June 22nd, totalling 796-meters. Drilling completed to date has focused on the 4-T Expansion and Extension targets. Samples for the first two drill holes have been submitted to the lab for analysis. Samples for the other two completed holes will be submitted later this week. Results are pending. As drilling continues, follow-up drilling on the new Discovery Trend is planned next for targeting.

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 and San Francisco. The project is 140 kilometers north of Hermosillo and totals 2,414 hectares. Mineralization has been identified across the property totalling over six kilometers of prospective trends. Surface sampling has identified high-grade gold and silver values. Primary target areas are summarized below:
1.4 km prospective trend;
Several historic mine workings associated with low angle faults;

Quality Assurance / Quality Control
RC chips 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.
