Calgary, Alberta – TheNewswire - September 13, 2022 - Tocvan Ventures Corp. (the "Company") TOC; TCVNF; (FSE:TV3), is pleased to announce the completion of data compilation and surface evaluation of the San Ramon Prospect within the El Picacho Gold-Silver Project in Sonora, Mexico. Historic underground sampling competed by Timmins Gold in 2008, returned 23 one to two-meter rock chip samples ranging from 0.3 g/t Au to 22 g/t Au with Ag values up to 26 g/t (see Figure 1). Later sampling in 2016 by Millrock confirmed the high-grade results with five rock chip samples returning between 2.0 g/t Au to 18 g/t Au. The underground drive is thought to be completed between the 1950's and 1970's. A second underground working located 250-meters to the north returned nine rock chip samples ranging between 0.5 g/t Au and 8.2 g/t Au with Ag values up to 32 g/t (see Tables 1 & 2 for results). At San Ramon, high-grade gold values are recorded at surface over a 500-meter trend along a regional thrust fault contact. The Priority drill target area includes this trend plus the down-dip extension along the fault at depth to the west over 500-meters. The regional thrust fault is thought to be a major conduit for mineralization and both the older Precambrian gneiss and the younger Jurassic sediments below the fault show indications of strong alteration and high-grade mineralization.

"The data clearly shows that San Ramon is a high-priority target showcasing mineralization from surface to a minimum depth of 60-meters, over a 500-meter trend and open in all directions.", commented CEO, Brodie Sutherland. "Past work has de-risked this target as we know mineralization extends to depth from historic drill logs. The high-grade gold and silver seen at surface and recorded from the underground workings confirms a robust system is present. Follow-up grid drilling of the area will be a priority for El Picacho's development."

Discussion
The San Ramon Prospect has significant historic workings that include two underground workings thought to be completed between the 1950's and 1970's. Sampling of the underground by past operators has returned consistent high-grade gold and silver mineralization within silicified quartz-carbonate veins hosted within shear zones parallel to a large regional fault that dips shallowly to the west. Mineralization does not appear to be isolated to the Precambrian gneiss host rocks in the hangingwall of the fault but also present in the younger Jurassic sediments (sandstones to dolostones) in the footwall. This is most evident 1.4 kilometers to the south at the Murcielago Prospect where mineralization is hosted within a brecciated dolostone.
The target area currently consists of a 500-meter by 500-meter area focused around historic workings trending south along the contact of a regional fault. Reconnaissance drilling completed by Timmins Gold in 2012 and 2013 identified multiple mineralized horizons (low-angle shear zones) hosting gold and silver mineralization down to a depth of 60-meters. These shear zones align with high-grade mineralization outcropping at surface and sampled in the underground workings. Although follow-up grid drilling was planned, due to budgetary constraints by Timmins Gold and priorities towards near-mine exploration, no follow-up work was completed at the San Ramon Prospect. The Company believes the past drilling has proven the model for a continuation of mineralization at depth and that follow-up drilling is needed to intersect the higher-grades recorded in the underground workings. The San Francisco deposit is hosted within the same rock type seen at San Ramon and is related to similar regional faults. With the rain season coming to an end in Sonora, planning is underway to initiate drilling at San Ramon as soon as possible.

90-meter underground drive, chip samples returned from 0.3 to 22 g/t Au over length of drive. Averaging 5.0 g/t Au and 8 g/t Ag.
-
See Figure 2 and Table 1
-
-

Coordinate System: WGS84, Zone 12. Historic samples were taken over 1 to 2-meter chips.
Three Historic Reconnaissance Drill Holes (Timmins Gold, 2012) were completed. All three Intersected Mineralization. No follow-up work was completed due to a stop in regional exploration by Timmins Gold at the time.

About the 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. 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. The project has only seen widely spaced reconnaissance drilling with no follow-up. Tocvan believes this provides an excellent opportunity for discovery of a muti-million ounce district.
