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
Tocvan Ventures Corp. has released 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 Sept. 29, 2020,
several significant conclusions were made, one of which is the interpretation of a subvertical pipe-like feature in the east-central part of the property, this feature may represent a breccia feeder pipe related to epithermal mineralization. The pipe is about 100 metres in diameter, oval shaped and has a steep plunge (about 70 degrees) to south-southwest with a 195-degree azimuth.
A second circular feature is noted through geochemistry analysis and is tentatively interpreted as a pipe-like feature. It is located in the southeast part of the property, and is southeast of the pipe-like feature described above; interestingly, both pipe-like features follow the main northwest to southeast 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 grams per tonne silver) and the highest rock grab silver assay result recorded on the property (323 g/t Ag) (press release dated Jan. 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 dated June 24, 2020).
Key to note, the
second circular feature located in the southeast part of the property
(press release dated Sept. 29, 2020), tentatively interpreted as a pipe-like feature, is coincident with the recently discovered
high-grade silver East zone (press release dated 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 (greater than one ounce per ton) of gold and silver.
The current world health situation requires adjustments to work programs; health and safety are 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 northwest 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 northwest-southeast trend of mineralization. Over 17,700 m of drilling have been completed to date. Significant results are highlighted below from previous operators:
- 17,700 metres of core and RC drilling; highlights include (all lengths are drilled thicknesses):
- 0.73 g/t Au over 40 m;
- 0.75 g/t Au over 61 m;
- 17.3 g/t Au over 1.5 m;
5.27 g/t Au over three m;
- 53.47 g/t Au and 53.4 g/t Ag over 16 m;
9.64 g/t Au over 13 m;
10.6 g/t Au and 37.8 g/t Ag over nine m;
2,650 m of surface and trench channel sampling; highlights include:
- 55 g/t Au over three m;
28.6 g/t Au over six m;
- 3.39 g/t Au over 50 m;
- Soil sampling results from undrilled areas indicating mineralization extends toward 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 northwest-southeast 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 Jan. 7, 2020. Significant results from that particular survey are highlighted in the associated table.
