Tocvan Identifies Drill Targets at Pilar Gold-Silver Project
Calgary, Alberta -- September 29, 2020 -- NewsGenie -- Tocvan Ventures Corp. (CSE:TOC) has announced key observations from technical studies aimed at identifying Phase 1 drill-hole targets at the Pilar Gold-Silver Project in Sonora, Mexico.
Work on the Pilar project since November 2019 has revealed a gold-silver mineralized trend extending southeast from the main drilled area, a parallel mineralized trend to the east, a new high-grade silver zone (East Zone), and gold-silver mineralization extending across the property from north to south. Data synthesis is underway to refine drill-hole targets, and the permitting process has begun.
Several consulting firms were involved in joint examinations; Jeremy S. Brett, M.Sc., P.Geo., Senior Geophysical Consultant with MPH Consulting Limited, Sandy M. Archibald, Ph.D., P.Geo. (PGO), Aurum Exploration Services (geochemistry), David Lewis, M.Sc., P.Geo. (PGO), consulting structural geologist, and Rodrigo Calles Montijo,\u00a0Ing. Geo., CPG-QP , IMEx Servicios Geologicos. Rodrigo is based in Hermosillo and provides a full-service exploration consulting firm.
A significant conclusion from the geophysical, geochemical, and structural specialists is the interpretation of a sub-vertical pipe-like feature that may represent a breccia feeder pipe related to epithermal mineralization. The pipe is ~100m in diameter, oval shaped, and has a steep plunge (~70\u00b0) to SSW with a 195\u00b0 azimuth. The pipe location appears to be controlled by a fold nose. Silica caps were indicated based on geological mapping and interpretation of shallow soil geochemistry, and it is recommended that these locations be drill-tested. Geophysical interpretation estimated that the silica caps extend to an approximate depth of 150m with a varying boundary\/transition into the host rock.

Note on Figure2. 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. This is quite visible in the 3D inversion in Figure 3.
Figure 3 - A 3D Inversion of the Induced Polarization Resistivity data (looking west from below). A discrete ~100m diameter oval pipe target is interpreted, bounded below only by the depth of investigation of the IP survey. It appears to dip to the SSW (azimuth 195\u00b0), with a steep plunge (~70\u00b0).
The Pilar Gold-Silver property is interpreted as a structurally controlled low-sulphidation epithermal project hosted in andesite and rhyolite rocks. Over 17,700m of drilling have been completed to date. Highlights include 0.73g\/t Au over 40m, 53.47g\/t Au 53.4g\/t Ag over 16m, and 55g\/t Au over 3m from surface and trench channel sampling.
