Tocvan Discovers New Gold - Silver Trend at Picacho Project; Rock Chips Return up to 15.9 g/t Gold, Plus Rock Float with Coarse Visible Gold Specimen Found
CALGARY, AB / ACCESSWIRE /January 23, 2024 / Tocvan Ventures Corp. (the "Company") (CSE:TOC);(OTCQB:TCVNF);(FSE:TV3), is pleased to announce results from its road accessible Picacho gold-silver project in the mine-friendly State of Sonora, Mexico. A short surface program was completed at Picacho to assess additional potential across the large 24-square kilometer property. A total of 75 rock chip samples were collected, averaging 0.6 g/t Au and 2 g/t Ag with the values up to 15.9 g/t Au and 32 g/t Ag (Table 1). A new mineralized trend extending over 1.6-kilometers in length has been discovered marked by old historic workings and exposure of mineralized veins and shear zones. The results are summarized below.

"Picacho continues to provide excellent targets and validation for drill testing across the extensive property." commented Brodie Sutherland, CEO. "We now have defined over seven kilometers of prospective trend that has seen little to no drilling, leaving the area as one of the most prospective and untested exploration properties in the Caborca Gold Belt. The discovery by our local rancher of a quartz vein rock fragment along a fresh bulldozer track displays the coarse high-grade gold potential at Picacho. The proximity of the specimen sample to our San Ramon prospect where we drilled and discovered near surface gold-silver mineralization in our first drill program at Picacho indicates the potential to extend known mineralization in the area. Fresnillo, the world's largest silver producer, and Mexico's largest gold producer, controls the mineral concession title along the eastern border of Picacho. Picacho will provide us with continued exploration upside for our shareholders as we remain focused on the development of Pilar. We are pleased to be in the position to have two projects with immense upside. At Pilar, the data processing of the LiDAR survey is complete for the southern half of the property with the remaining northern half expected to be complete in February."
About the Picacho Property The Picacho Gold-Silver property is interpreted as an orogenic gold system within the regional Caborca 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 past producing San Francisco Mine. The Project totals 24 square kilometers. Six primary zones of mineralization have been identified across the property totalling over seven kilometers of prospective trends. Surface sampling and historic workings have identified high-grade gold and silver values. In 2022, Tocvan drilled a maiden drill program at the San Ramon prospect returning 12.2-meters of 2.0 g/t Au and 7 g/t Ag. Tocvan believes Picacho provides an excellent opportunity for discovery of a muti-million ounce district.

About Tocvan Ventures Corp. Tocvan is a well-structured exploration development company. Tocvan was created in order to take advantage of the prolonged downturn in the junior mining exploration sector, by identifying and negotiating interest in opportunities where management feels they can build upon previous success. Tocvan has approximately 43 million shares outstanding and is earning 100% into two exciting opportunities in Sonora, Mexico: the Pilar Gold-Silver project and the Picacho Gold-Silver project. Management feels both projects represent tremendous opportunity to create shareholder value.
2023 Discoveries and Notable Highlights Advancement in 2023 continued with the Company's maiden drill program at Picacho discovering at surface gold and silver mineralization at the San Ramon prospect. Drilling returned 44.2-meters of 0.6 g/t Au, including 12.2-meters of 2.0 g/t Au and 7 g/t Ag. 200-meters to the north a hole intersected 27.5-meters of 0.5 g/t Au, including 12.2-meters of 1.1 g/t Au. The San Ramon prospect remains open for drill targeting in all directions. At Pilar, a bulk sample was extracted and shipped (1,400 tonnes) to a nearby processing mill for crushing and stacking for heap leach. Heap leaching was conducted over a 46-day period returning a head grade of 1.9 g/t Au and 7 g/t Ag with an initial recovery of 62% for gold. Agitated bottle roll test of the bulk sample material returned 80% recovery of gold and 94% recovery of silver after a rapid 24-hour retention time. Additional surface and core composites from across Pilar returned 95 to 99% recovery of gold and between 73 to 97% recovery of silver through combined gravity and agitated leach processing. An initial doré bar was later poured from the bulk sample material totalling 1.487 kilograms, containing 18% gold and 69% silver. A second gold-rich doré bar is scheduled to be poured this month. Channel sampling of newly opened trenches at Pilar returned similar values to the bulk sample highlighted by 20-meters of 1.9 g/t Au and 9 g/t Ag. A property wide LiDAR survey that will be used for the base map for mine design at Pilar is near completion. Additional reconnaissance sampling across Pilar and Picacho projects are ongoing to advance target areas, results for initial samples are pending.
2024 Key Objectives:
Resource Infill and Expansion Drilling
Maiden Resource Estimate Q4, 2024
Mine Planning and Design
Submit Applications for:
MIA (Manifestación de Impacto Ambiental) or Environmental Impact Statement
EJT (Estudio Técnico Justificativo) or Technical Justification Study
Continued Metallurgical Testing
1:5,000 scale Geological Mapping and Sampling of New Expansion Area
Trenching and Channel Sampling of New Targets
Geophysical Surveys, including magnetics
Discovery Drilling
2024 Outlook Tocvan's primary objectives for 2024 are to de-risk the Pilar project further with maiden resource estimation and the submission of mine permitting applications. The ongoing LiDAR survey will be used as the base map for mine development design and planning, an integral part to the next phase of the permitting process. Hydrological and environmental studies are scheduled to complete the MIA. While the permits are in process the Company will evaluate the need and timing for a maiden PEA to assist in securing later mine construction financing.
Other objectives with the potential to yield high returns include the advancement of priority drill targets within the new expansion area at Pilar. With the new area around Pilar consolidated, current target areas are numerous and untested. Picacho remains a highly attractive project for drill targeting and Tocvan will continue to advance prospects there for future drill programs. Collectively across the two projects Tocvan controls over 45-square kilometers of prospective ground where the Company is targeting multi-million-ounce potential. Exploration work on both projects will remain ongoing with detailed geological mapping, surface channel and chip sampling and geophysics. In addition, continued metallurgical studies will advance the understanding to optimize future processing of material from Pilar.

Quality Assurance / Quality Control Channel 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.
