Tocvan Announces the Association of the High-Grade Silver East Zone With a Pipe-Like Feature, at the Pilar Gold-Silver Project in Sonora, Mexico
Calgary, October 15, 2020 - Tocvan Ventures Corp. (CSE:TOC) (CNSX:TOC.CN) ("Tocvan" or the "Corporation") is pleased to announce additional key observations and conclusions from recent technical studies focused on the identification of a Phase 1 program of drill-hole targets at the Pilar Gold-Silver Project in Sonora, Mexico. As noted in the most recent press release dated September 29, 2020, several significant conclusions were made, one of which is the interpretation of a sub-vertical pipe-like feature in the east-central part of the property, this feature may represent a breccia feeder pipe related to epithermal mineralization (Figures 1, 2). The pipe is ~100m in diameter, oval shaped, and has a steep plunge (~70?) to SSW with a 195? azimuth.
A second circular feature is noted through geochemistry analysis and is tentatively interpreted as a pipe-like feature. It is located in the south-east part of the property, and is south-east of the pipe-like feature described above, interestingly both pipe-like features follow the main north-west to south-east shear structure that runs across the property.
Interesting to note, are the results of the assay soil survey program released in the press release dated June 24, 2020 where the highest soil silver assay result was recorded on the property (317 g/t Ag) and the highest rock-grab silver assay result recorded on the property (323 g/t Ag) (press release: January 7, 2020). Other discoveries and assay results taken together revealed a second parallel mineralized trend of gold and silver to the east of the drilled area and a new high-grade silver zone termed the East Zone (press release: June 24, 2020) (Figure 3).
Key to note, the second circular feature located in the south-east part of the property (Figure 2) (press release: September 29, 2020), tentatively interpreted as a pipe-like feature, is coincident with the recently discovered high-grade silver East Zone (Figure 3) (press release: June 24, 2020), in fact the two highest silver assay results are in this area, along with several other gold and silver high grade results. Pipes, and breccia-pipes are significant features in epithermal gold-silver models and can hold bonanza grades (>1opt) of gold and silver.

Note on Figure1. An Induced Polarization Resistivity Inversion depth slice at 325m ASL is shown, with interpretation notes. A significant NNW-SSE ~100m wide corridor is present as a strong resistivity low, and is coincident with much of the drilling performed on the property to date. It is interpreted as increased rock porosity related to an alteration corridor. Another resistivity low is present to the east of this, and takes the form of a discrete 100m diameter oval. Although visibly controlled by a NNE-SSW structure, it terminates abruptly and is interpreted as a potential epithermal feeder pipe.

Special Note:
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 is interpreted as a structurally controlled low-sulphidation epithermal project hosted in andesite and rhyolite rocks. Hydrothermal fluids carrying gold, silver and other elements are transported through the pre-existing structures and precipitate from the fluids to become mineralized veins 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
- 17.3g/t Au over 1.5m
- 5.27g/t Au over 3m
- 53.47g/t Au & 53.4g/t Ag over 16m
- 9.64g/t Au over 13m
- 10.6g/t Au & 37.8g/t Ag over 9m
- 2,650m of surface and trench channel sampling. Highlights include:
-
- 55g/t Au over 3m
- 28.6g/t Au over 6m
- 3.39 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:
