Vizsla Silver Corp. (TSX-V: VZLA) (NYSE: VZLA) (Frankfurt: 0G3) ("Vizsla" or the "Company" - https://www.commodity-tv.com/ondemand/companies/profil/vizsla-silver-corp/ ) is pleased to announce initial metallurgical test results for the Napoleon Resource Area ("Napoleon") at its 100%-owned flagship Panuco silver-gold project ("Panuco" or the "Project") located in Mexico.
Highlights:
Metallurgical Test Program Overview
As the first metallurgical testing program conducted by Vizsla at Panuco, the objective was to assess the wide range of viable processing alternatives that could be applied to successfully recover precious and base metals from mineralized material at Napoleon. The metallurgical test program consisted of geo-metallurgical characterization, comminution testing, cyanide leach testing, gravity recovery, grind size sensitivity, bulk and sequential flotation assessments.
A total of ~330 kg of core material was selected from six mineralized drill holes defining ten litho-based point samples. The rationale for sample selection considered primary lithologies, spatial coverage and representation, contiguous mineralization, distribution of grade and potential dilution. The samples were blended to create a 65 kg master composite, which all subsequent tests were based on.
The test program was designed and supervised by Ausenco Engineering Canada Inc. and completed by ALS Canada Ltd. out of Kamloops, BC.
Sequential & Bulk Flotation: Conventional open circuit sequential lead rougher and zinc rougher flotation tests were conducted on the master composite to assess the sample’s amenability to recover precious and base metals into separate marketable lead and zinc concentrates. Grind size sensitivity analysis highlighted a P80 of 63 µm as the potential optimum primary grind. Following the rougher steps, the individual lead and zinc concentrates were reground (P80 of 19 µm for lead and 36 µm for zinc) and subjected (respectively) to a two-stage open circuit cleaner flotation testwork.
Open circuit bulk rougher and cleaner flotation tests were conducted to investigate the sample’s amenability to recover base and precious metals into a single marketable concentrate. The bulk rougher concentrate was reground and subjected to open circuit cleaner flotation testwork consisting of two stages. Based on the sequential flotation testing results, a P80 of 63 µm was selected as the primary grind, while 31 µm was selected as the regrind target.
Cyanide Leaching: Bottle roll cyanidation testing was completed on the Napoleon master composite using a grind size of P80 63 µm, retention time of 48 hours, and a pH of 11-11.5. Results indicate a strong extraction profile, yielding 93% for gold and 87% for silver after 48 hours. Reagent consumption was 2.5 kg/tonne of NACN and 0.5 kg/tonne of lime. Liquor assays indicated low levels of impurities indicating leaching was highly successful in selectively leaching precious metals from the mineralization with limited dissolution of other elements.
Gravity Testing: The program tested the Napoleon master composite response to gravity concentration via a Knelson concentrator followed by a hand panning program. Consistent with the other tests, a grind size of P80 63 µm was selected. Whole ore gravity testing demonstrated that 40% Au and 29% Ag were recoverable.
Comminution: The Napoleon composite material is considered to be a moderately hard mill feed, returning a bond ball work index (BBWi) of 16.8 kWh/tonne, which is consistent with similar ore material from nearby Mexican projects.
Future Work Programs
Based on these attractive results, the Company plans to complete further metallurgical testwork following the announcement of its maiden resource estimate in Q1 2022.
Similar metallurgical testwork is currently underway for the Tajitos area mineralization. Once complete, the combined metallurgical test results will guide the processing strategy for potential development of the western portion of the Panuco district.
About the Panuco project
The newly consolidated Panuco silver-gold project is an emerging high-grade discovery located in southern Sinaloa, Mexico, near the city of Mazatlán. The 6,754-hectare, past producing district benefits from over 75 kilometres of total vein extent, a 500 ton per day mill, 35 kilometres 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.

To date, Vizsla has completed over 120,000 meters of drilling at Panuco leading to the discovery of several new high-grade veins. With an ongoing fully funded +120,000-meter drill program, the Company is well positioned to deliver a maiden project resource in the first quarter of 2022 while in parallel continuing to explore the significant upside potential remaining in the district.
About Ausenco

Combining their deep technical expertise with a 30-year track record, they provide innovative, value-add consulting and engineering studies and project delivery, asset operations and maintenance solutions to the mining & metals, oil & gas, and industrial sectors.
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 ("AA") 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.
