Tocvan Ventures Corp. Announce Drill Results for the Remaining Drill Holes Completed At Its El Picacho Gold-Silver Project in Sonora, Mexico
Tocvan Ventures Corp. announce drill results for the remaining drill holes completed at its El Picacho Gold-Silver project in Sonora, Mexico. Ten drill holes totaling 1,075.1-meters were completed at the San Ramon Prospect testing for low-grade mineralization adjacent to historic underground workings that have returned high-grade gold with silver. Drilling aimed to test different structural orientations to determine the best way to target mineralization. Mineralization associated with historic underground workings was confirmed and the most significant mineralization was discovered in a 100-meter step- out from the historic workings of the San Ramon target, confirming the model that mineralization continues at depth in west-dipping system. Hole SRA-22-010, returned the most significant results to date intersecting 44.2-meters of 0.6 g/t Au, including 12.2-meters of 2.0 g/t Au and 7 g/t Ag from a downhole depth of 41.2-meters (approx. 25-meters from surface). Mineralization has now been intersected over a 300-meter strike and 200-meters down-dip from the surface exposure. Analysis and interpretation of this data will be used to plan follow-up drilling. El Picacho is host to several other target areas permitted for drilling that span across the 24 km2 project area. Other Highlights Hole SRA-22-004 returned 13.7-meters of 5 g/t Ag, from 128.1-meters Confirms Mineralization in Lower Metasediments 2 g/t Ag over 100.6-meters · Hole SRA-22-005 returned 4.6-meters of 0.5 g/t Au and 5 g/t Ag, from 21.4-meters Hole SRA-22-007 returned 7.6-meters of 0.3 g/t Au and 17 g/t Ag, from 24.4-meters Including 3.1-meters of 0.6 g/t Au and 31 g/t Ag. The drill program was successful in identifying mineralization in three target areas: Las Guijas, San Ramon and the newly discovered extension to San Ramon. Initial review of the data suggest drilling in a southeast direction (azimuth 120) provides the best result for testing high-grade mineralization and adjacent low-grade. Hole SRA-22-010 has proven the model of a west-dipping package of altered and mineralized quartz veins and shear zones exist and appear to continue at depth and remain open to the west and south of the known area. A detailed account of the key drill holes is provided below. SRA-22-010 Azimuth 120, Dip -45o, Total Depth 180.0m This hole targeted a 100-meter step-out on trend and down-dip of known mineralization projected from the San Ramon underground workings. From surface to 45.8-meters depth a moderately oxidized zone within gneiss was intersected with two 3-meters zones of veining and pyrite, although altered no significant mineralization was recorded in this upper zone. At 45.8-meters a fault was encountered transitioning into a vein zone to 58.0-meters. This vein zone hosts the majority of high-grade gold mineralization averaging 2.0 g/t Au over 12.2-meters, with values up to 14.2 g/t Au. Below the vein zone anomalous mineralization (Au and Ag) continues until 90.0-meters depth where it then breaks up into several anomalous zones before transitioning to a weakly altered/oxidized diorite at 164.7-meters. Through the vein zone anomalous Au, Ag, As, Sb and Pb are recorded averaging 2.0 g/t Au, 7 g/t Ag, 246 ppm As, 168 ppm Sb and 381 ppb Pb. SRA-22-008 Azimuth 115, Dip -65o, Total Depth 151.0m This hole targeted the area adjacent and underneath the San Ramon underground workings. A weakly oxidized diorite was recorded from surface to 12.2-meters depth transitioning into a silicified diorite and vein zone until 45.8-meters depth. The vein zone returned the strongest mineralization from 21.4-meters to 38.1-meters returning 16.8-meters of 0.5 g/t Au, including 4.6-meters of 1.8 g/t Au and 6 g/t Ag. Anomalous pathfinder elements (As, Sb, Pb and Zn) were recorded through the vein zone. Alteration weakens at 54.9-meters depth. At 79.3-meters the gneiss unit was encountered until 122.0- meters depth were the lithology changed to a metasediment unit for the remainder of the hole. Anomalous Ag, W and Cu were recorded in the lower metasediment unit. SRA-22-005 Azimuth 130, Dip -45o, Total Depth 100.7m This hole targeted the area adjacent and underneath the San Ramon underground workings at its eastern-most extent. A weakly oxidized diorite was recorded from surface to 18.3-meters before coming into an oxidized vein zone from 18.3- meters to 36.6-meters. The vein zone returned anomalous Au, Ag, As, Ab, W, Pb and Zn with Au values up to 1.0 g/t and Ag values up to 18.3 g/t. Below the vein zone a weakly altered diorite was recorded to 79.3-meters where a felsic dyke was encountered until 91.5-meters followed by the metasedimentary unit until the end of hole. The remaining holes all hit anomalous mineralization and veining with elevated path finder elements while testing different orientations. Although no significant mineralization was recorded the technical team views this as a great indicator of a robust mineralized system. Hole SRA-22-004 intersected a vein zone from 18.3-meters to 29.0-meters with elevated Au, Ag, As, Sb and Zn. A lower metasediment unit returned elevated Ag and As nearly over the entire length, recording 2 g/t Ag over 100.6-meters. Hole SRA-22-006 intersected a section of discontinuous veins before encountering an underground void at 27.5-meters. Hole SRA-22-007 also hit an underground void just after entering a vein zone from 21.4-meters depth with Au values up to 1.0 g/t and Ag values up to 54 g/t. Hole SRA-22-009 recorded a vein zone from 13.7-meters to 36.6- meters with anomalous Au, Ag, As, Sb, W, Pb and Zn.
