Calgary, Alberta – TheNewswire - September 19, 2022 -Tocvan Ventures Corp. (the “Company”) (CSE:TOC); (OTC:TCVNF); (FSE:TV3), is pleased to announce an operational update for both gold-silver projects in Sonora, Mexico. With the conclusion of the wet weather season approaching, the Company plans to first initiate drilling at El Picacho with a maiden drill program targeting the San Ramon prospect (see news release, September 13, 2022). Drilling will target the 500-meter by 500-meter prospective area where high-grade gold at surface and in underground workings have outlined the potential for a near-surface bulk tonnage target. At Pilar, planning is underway for the next stage of exploration and development. A bulk sample is scheduled to begin preparation in October and November, utilizing a local heap leach facility to process material from Pilar. An independent Qualified Professional will oversee the operations to ensure the accuracy of the results. The outcome will provide useful data to assist in proceeding with the permitting and development requirements for establishing a bulk test mine on-site. Exploration at Pilar will continue with drilling scheduled to follow-up on key expansion target areas and provide infill data along established mineralized domains for future resource calculations.

“Over the last year we have seen a major advancement in our understanding of our Pilar and El Picacho projects.”, commented CEO, Brodie Sutherland. “We are excited to continue that advancement with the first large scale bulk sample at Pilar to further confirm the grade and recovery of gold and silver. This information will lead us into permitting for our own pilot facility at Pilar. At the same time, drilling will commence at our El Picacho project initially targeting our highly prospective San Ramon area, one of several target areas permitted for drilling. Pilar still has potential for expansion and will remain a focus for us with continued drilling on several trends that remain open to the southeast. Our success over the past two years has gained a lot of interest from large-scale producers in the region, we look forward to building off that success and developing strong relationships during the upcoming operating season and beyond.”

Discussion
As the Company looks to advance Pilar towards production with bulk sampling and more advanced metallurgical analysis it is important to note the key advantages of operating in a quality mining jurisdiction.
Why Mine in Sonora, Mexico
-
Low-cost operations
-
Sonora is renowned for low-cost, open pit, heap leachable deposits
-
These low-cost parameters provide a shelter from inflationary prices and fluctuating metal prices
-
Below summarizes some local examples of the estimated Mine Costs from three producers
-
Minable grades typically range from 0.4 g/t Au to 1.0 g/t Au, with recoveries ranging from 50-90%
-
Results from Pilar are above the regional average for both parameters

2. At surface oxide gold-silver amenable to heap-leach
-
Mineralization at Pilar outcrops at surface in a highly fractured and oxidized host rock.
-
Metallurgical studies, both bottle roll and column leach show recovery of gold to be above the regional average giving the Company confidence in conducting bulk sampling to confirm average head grades and recovery.
3. Excellent infrastructure
-
Tocvan Projects are fully-road accessible to all current target areas.
-
Pilar is located 130 km southeast of the capital of Sonora, Hermosillo. Approximately 2 hours drive from Hermosillo to the town of Suaqui Grande on paved highway. From Suaqui Grande to the project site is approximately 30 mins on gravel road.
-
The El Picacho property is located approximately 145 km north of Hermosillo and 18 km southwest of the San Francisco Mine. Access is off of a State Highway and a series of dirt roads. The site takes approximately 2 hours to drive to from Hermosillo and has a rail line located just a few kilometers east of the project boundary.
4. Strong local technical expertise
-
The long history of mining in Sonora has fostered industry leading technical personnel in the understanding and development of heap leach process facilities and mine development.
-
Tocvan is proud to have a team of local industry experts with proven experience in the development of projects.
5. Straightforward and established permitting process
6. A quality jurisdiction, home to major producers and potential development partners
-
Both of Tocvan’s Projects are proximal to currently producing mines or projects moving towards development
-
At Pilar, three major projects are close by:
-
Osisko Development’s San Antonio Project – 25-kilometers north
-
Minera Alamos’ Santana Mine - 50-kilometers to the east
-
Argonaut Gold’s La Colorada Mine – 80-kilometers to the northwest
-
At El Picacho, the project is within the Caborca Orogenic Gold Belt also referred to as the Mojave-Sonora Megashear. This trend is host to major deposits such as Fresnillo’s La Herradura Mine and MagnaGold’s San Francisco Mine, just 18-kilometers northeast of El Picacho
-
The Company is well positioned to attract a major development partner in the region.

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 22,000 m of drilling has been completed.

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.
