Vizsla Resources Corp. (TSX-V: VZLA) (OTCQB: VIZSF) (Frankfurt: 0G3) is pleased to provide the first results from the Aguita Zarca prospect on the Corden del Oro Vein at the Panuco silver-gold project in Mexico. These results are from the first drillhole testing a series of closely spaced veins in a new target area with oxidised mineralization almost from surface.

CO-20-13
Note: All numbers are rounded and widths represent downhole lengths. True width is estimated at 67% of the downhole length. Silver equivalent is calculated using the following formula: Silver-equivalent = ((Au_g/t x 52.48) + (Ag_g/t x 0.5289)) / 0.5627. For silver-equivalent calculations, metal price assumptions are $17.50 g/t silver and $1,700 g/t gold, recoveries assumptions are 96% gold and 94% silver based on similar deposit types. The Company is disclosing results on a silver equivalent basis due to the overall silver dominant nature of mineralization at the Panuco project. |
Vizsla President and CEO, Michael Konnert, commented: “Drilling such a broad zone of veining at the Aguita Zarca prospect is another significant step forward for the Panuco project. This new zone is located over 5km east of our initial discovery at Napoleon and is located on the Cordon del Oro vein corridor, which has never been drilled before. The Aquita Zarca zone has significant size potential with a 400m strike length with surface mineralization and multiple closely spaced veins. 2020 has been an incredibly successful year and the Company continues to aggressively unlock the potential of Panuco. This is a clear demonstration of the upside that drilling can unlock at the underexplored Panuco district. Vizsla is drilling with five rigs across the district and is funded for an even more aggressive 2021.”
Aguita Zarca Drilling Detail
The Aguita Zarca prospect was defined in the middle of this year with detailed field mapping and surface sampling along the Cordon del Oro vein corridor. The prospect is only 1,300 m to the west southwest of the El Coco Mill and San Carlos mine but occurs at a 160 metre higher elevation. It occurs along the Cordon del Oro trend that has wide veins over long distances and the Company believes represents a less eroded version of the adjacent Animas vein corridor. The trend has never previously been drilled and contains multiple small-scale workings.
Mineralization has been sampled at surface over 400 meters of strike and contains a continuous chip channel intercept of 18.85 metres grading 197g/t silver equivalent above the drill hole that is open in both directions. The target is particularly interesting as it occurs at a major bend in the Corden del Oro corridor where multiple veins are splitting off the main structure into a wide corridor of veining. Further the slightly higher-level textures observed in the veins, gold rich nature of mineralisation and higher elevation relative to the Animas vein suggests the main mineralized zones may exist at depth beneath the current drilling.
Hole CO-20-13 targeted the Aguita Zarca vein and drilled through mine workings on the main vein from 21-25.5 metres downhole, then through a wide corridor of variably intense veining known as the Pinito vein and finally across the Aguita Zarca vein at depth.
Follow-up holes were drilled to the east and west from the same pad and then the drill rig has moved to drill from the hanging wall back into the footwall of the main vein. These holes have intersected similar veins and alteration to hole CO-20-13. The Company is preparing drill pads to allow for more significant step out holes to the southeast and northwest.
Holes CO-20-08 to CO-20-12 were completed in the Mojocuan area and reported no significant intersections.
The Cordon del Oro structure is a major NW trending fault zone that dips steeply to moderately to the NE and makes up the west side of the Animas – Refugio graben. The fault has been mapped along strike for over 10 km and varies in width from some 8 to 40 m wide. Various pulses of quartz veins have been deposited within the fault zone and some of these have been brecciated by later movement along the fault. In addition to the main veins within the plane of the fault, there are a number of hanging wall splays – such as the Aguita Zarca vein – and horsetail splays – such as the Pintos zone of veining, where there are bends in the main trend.
The veins are mainly white to locally grey quartz with a massive texture to locally banded, that are usually hosted in a rhyolite tuff which in some areas is just above the contact with a granodiorite intrusive. The veins are often white to grey quartz supporting brecciated clasts of rhyolite and having variable amounts of disseminated pyrite with lesser amounts of sphalerite or galena. In the area of CO-20-13, most of the sulphide has been oxidized leaving moderate to strong hematite along with variable amounts of manganese.

Table 1: Drilling and surface channel intersections from Aguita Zarca. True widths are estimated at 67% of downhole lengths and 81% of channel sample lengths. Due to the oxide nature of mineralization a topcut silver equivalent has been presented to limit the effect of remobilized gold. The topcut limits any gold samples above 30 g/t to this number.
Note: All numbers are rounded and widths represent downhole lengths. Silver equivalent is calculated using the following formula: Silver-equivalent = ((Au_g/t x 52.48) + (Ag_g/t x 0.5289)) / 0.5627. For silver-equivalent calculations, metal price assumptions are $17.50 g/t silver and $1,700 g/t gold, recoveries assumptions are 96% gold and 94% silver, based on similar deposit types. |

About the Panuco project
Vizsla has an option to acquire 100% of the recently consolidated 9,386.5 Ha Panuco district in southern Sinaloa, Mexico, near the city of Mazatlán. The option allows for the acquisition of over 75 km of total vein extent, a 500 tpd mill, 35 kms of underground mines, tailings facilities, roads, power and permits.
The district contains intermediate to low sulfidation epithermal silver and gold deposits related to siliceous volcanism and crustal extension in the Oligocene and Miocene. Host rocks are mainly continental volcanic rocks correlated to the Tarahumara Formation.
Quality Assurance / Quality Control
Drill core and rock samples were shipped to ALS Limited in Zacatecas, Zacatecas, Mexico and in North Vancouver, Canada for sample preparation and for analysis at the ALS laboratory in North Vancouver. The ALS Zacatecas and North Vancouver facilities are ISO 9001 and ISO/IEC 17025 certified. Silver and base metals were analyzed using a four-acid digestion with an ICP finish and gold was assayed by 30-gram fire assay with atomic absorption spectroscopy finish. Over limit analyses for silver, lead and zinc were re-assayed using an ore-grade four-acid digestion with AA finish.
Control samples comprising certified reference samples, duplicates and blank samples were systematically inserted into the sample stream and analyzed as part of the Company’s quality assurance / quality control protocol.
