Calgary, Alberta – August 25, 2020. Tocvan Ventures Corp. (CSE: “TOC”) (“Tocvan” or the “Corporation”) is pleased to announce initial results from the structural analysis at the Pilar Gold-Silver Project in Sonora, Mexico.
Major significant large structures (“plumbing”) with significant depth extents containing additional structures favorable for gold-silver mineralization have been recognized on the property. These standout features cover a large area extending across the property from the NW to the SE.
Structural analyses have begun on the Pilar project incorporating all the data that has been collected to date. The goal is to establish drill targets to intercept grades similar to the high grades found in the historic hole S-10 of over 1.7oz/t gold and silver over an intercept of 16.5m located in the North Hill Zone (Figure 1b). Gold and silver are located within and about structures. Structures act as conduits or plumbing for metal-mineral-rich fluids to flow through and deposit.
The initial overview of the 3D inversion of magnetic susceptibility data has revealed stand-out significant major structures that are universally associated with “plumbing” systems for gold-silver fluid flow and deposition. It is important and key to note that epithermal-style mineralization, as with the Pilar project, rely on structure (“plumbing”) in order to form a gold and silver deposit. Structures appear as shear zones, faults, brecciated rock, rotational gashes within shear zones and other such dilation structures. Where there are structures of expansion and other openings then heated gold-silver bearing fluids can deposit.
For a high quality analysis two consulting firms have come together to begin a joint examination; Marion Iseppi Ph.D. Structural Geologist with SRK Consulting (Canada) Inc., and Jeremy S. Brett, M.Sc., P.Geo., Senior Geophysical Consultant with MPH Consulting Limited.
SRK commented “SRK Consulting initiated a structural analysis of the Pilar property. A preliminary structural analysis of recently acquired Ground Magnetic and Induced Polarization (IP) data revealed several areas of structural complexity that usually represent high permeability zones as well as post mineral faults that displace the supergene profile, and which may constitute post-mineralization reactivation of important syn-mineralization structures.” (Supergene is a mineral enrichment process that is known to deposit metals in higher contents as opposed to the primary ore).
There are several initial findings which include a major significant large structure trending NW-SE with approximate dimensions of 250m x 1000m with vertical extents measured in multiple 100’s metres extending to surface (Figure 1a, 2), and bounded within this main structure corridor are additional structures trending N-S with approximate lengths of 300m (Figure 1a). Previous workers performing a structural overview described the NW-SE structure as a structural corridor holding a shear zone with rotational features. Such features provide excellent means of plumbing for metal-mineral-rich fluids to flow through and deposit.

Figures 1a and 1b show a plan view of a 3D Inversion Magnetic Susceptibility slice at ~350m depth and the full Voxel of the magnetic Inversion. Comparing Figure 1a with Figure 1b, the vast majority of the historic drilling has primarily been at shallow depths extending to ~125m in the Main Zone and the North Hill Zone (the location of the S-10 drill hole with over 1.7oz/t gold and silver over 16.5m).
There is clear opportunity to intercept mineralized targets extending to depth, consistent with an epithermal-model of mineralization with the very real possibility, and goal, of intercepting high grade gold and silver similar to the historic S-10 hole.

Derek Wood CEO commented ” We are extremely enthusiastic that the work done at every stage of exploration since negotiating the option to acquire up to 100% interest in the Pilar property has exceeded expectations and increased our understanding and the potential of the property both as having near term production capability and now as potential to host a world class discovery.
Previous drilling had identified a high grade system at surface in the Northwest area of the property known as the Main Zone. Upcoming drilling will be focused on expanding areas of known high grade gold and silver mineralization at surface within areas of previous drilling success and also will now test newly discovered ‘at surface’ zones and will include deeper drilling to test the mineralization within the newly identified IP anomaly. I would like to thank Mark Smethurst for his work in advancing exploration activity on time and on budget in spite of challenges created by the Covid-19 Pandemic. “
The current world health situation requires adjustments to work programs, health and safety is considered first.
Current health advice is for families and groups to self-isolate and to use caution with suggested recommendations from health leaders when social-distancing becomes a challenge. Countries are beginning to allow businesses to operate again. Isolation is an inherent part of mineral development programs.
About the Pilar Property
The Pilar Gold-Silver property has been identified as a structurally controlled low-sulphidation epithermal project hosted in Andesite and Rhyolite rocks. Hydrothermal fluids carrying gold, silver and other minerals are transported through the pre-existing structures and deposit out of the fluids and become emplaced within the structures and surrounding host rock. Three 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 Trench. Structural features and zones of mineralization within the structures follow an overall NW-SE trend of mineralization. Over 17,700m of drilling have been completed to date. Significant results are highlighted below from previous operators:
- 17,700m of Core & RC drilling. Highlights include (all lengths are drilled thicknesses):
- 0.73g/t Au over 40m
- 0.75g/t Au over 61m
- 3g/t Au over 1.5m
- 27g/t Au over 3m
- 47g/t Au & 53.4g/t Ag over 16m
- 64g/t Au over 13m
- 6g/t Au & 37.8g/t Ag over 9m
- 2,650m of surface and trench channel sampling. Highlights include:
- 55g/t Au over 3m
- 6g/t Au over 6m
- 39 g/t Au over 50m
- Soil sampling results from undrilled areas indicating mineralization extends towards the southeast from the Main Zone, North Hill Zone, and 4-Trench Zone
Additional areas of mineralization have been identified resulting from surface rock-grab-sample assay results that extend known mineralized trends and show a second NW-SE trend of mineralization to the east parallel to the trending zone described above; gold-silver mineralization is indicated across the property from the north to the south, see press release dated January 7, 2020. Significant results from that particular survey are highlighted below:
