Vizsla Silver Restates Maiden Resource Estimate For Panuco Silver-Gold Project
"Vizsla Silver is retracting the maiden resource estimate published on February 28th and restating it in today's release," commented Michael Konnert, President and CEO. "An internal review of the estimate identified a miscalculation made by an independent consultant in the conversion of lead and zinc grades into the silver equivalent calculation. This in-turn lifted lower grade zones above the economic cut-off, adding tonnes to the resource but lowering the overall grade. Today's restatement corrects this, and the resource remains extremely robust. Vizsla management acknowledge and apologize for the miscalculation and will publish data along with the technical report within 30 days to allow investors to independently confirm the resource estimate. The Vizsla board is conducting a review into the Company's disclosure processes and will implement a technical committee for additional oversight moving forward."
Tim Maunula, P.Geo., Principal of T. Maunula & Associates Consulting Inc. commented: "We sincerely regret the miscalculation. It needs to be emphasized, however, that the data used in the model is sound and has been checked and verified and the grade estimation is also accurate."
Highlights of the Restated Resource Estimate:
Indicated Mineral Resources are estimated at 5.0 million tonnes ("Mt") grading 191 grams per tonne ("g/t") silver, 2.08 g/t gold, 0.26 % lead, and 0.50 % zinc (383 g/t silver equivalent ("AgEq")). The Resource Estimate includes indicated resources of 30.5 million ounces ("Moz") of silver, 331.1 thousand ounces ("koz") of gold, 13 kilo tonnes ("kt") of lead, and 24.6 kt of zinc (61.1 Moz AgEq).
Inferred Mineral Resources are estimated at 4.1 Mt grading 187 g/t silver, 1.79 g/t gold, 0.13 % lead, and 0.30 % zinc (345 g/t AgEq). The Resource Estimate includes inferred resource of 24.7 Moz of silver, 235.8 koz of gold, 5.3 kt of lead, and 12.4 kt of zinc (45.6 Moz AgEq).
The Resource Estimate is based on a total drill database of 445 holes (124,915 meters) completed by Vizsla between November 2019 and December 2021.
"This maiden resource estimate is a major milestone for Vizsla Silver," commented Michael Konnert. "It establishes Panuco as an extremely high-quality silver and gold district given its rare combination of size, grade and width, with significant room for growth. Every vein included in the resource estimate remains open for expansion. The grade tonnage curve demonstrates the deposit is relativity insensitive to higher cut-offs and within the Napoleon Vein, a high-grade subzone of 13.3 million ounces grading 648 g/t AgEq, named Gallinero, has been delineated. The resource comes only 18 months from the initial discovery at a total all-in exploration cost of US$0.23 per ounce. Looking ahead, the Company plans to update this maiden resource in the second half of 2022 on the back of its ongoing 120,000 metre infill/discovery-based drill program. I would like to thank the entire Vizsla Silver team, including our contractors and local communities, for their commitment and contribution to this achievement."
Vizsla Silver will be hosting a webcast to discuss the Resource Estimate at 11:30am PT on Thursday, March 3rd. To register, please click here.
A technical report is being prepared in accordance with National Instrument 43-101 ("NI-43-101") and will be available on the Company's website and SEDAR within 30 days of the date of this release. The effective date of the Resource Estimate is March 1, 2022.
The Resource Estimate included in the Company's February 28, 2022 news release should not be relied upon.

Panuco Project Mineral Resource Estimate Notes:
- The Resource Estimate is compliant with Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") Definition ?Standards incorporated by reference in NI 43-101 The effective date for the Resource Estimate is March 1, 2022.
- Resources are presented undiluted and in situ and are considered to have reasonable prospects for economic extraction assuming metals prices of $20.7 per ounce of silver, $1,650 per ounce of gold, $1,902 per tonne of lead and $2,505 per tonne of zinc.
- The database comprises a total of 445 drill holes for 124,915 metres of drilling completed by Vizsla Silver between November 2019 and December 2021.
- The Resource Estimate encompasses a total of 13 sub-vertical precious metals rich domains each defined by individual wireframes with a minimum true thickness of 2.0 metres for Napoleon (2 wireframes) and Tajitos (3 wireframes), and 1.5 metres thickness for the six other structures (8 wireframes).
- Samples were composited within the mineralized domains into 1.50 metre length composites.
- High grade capping was done on composite data and established using a statistical analysis on a per-zone basis for silver, gold, lead and zinc.
- Cut-off grade of 150 g/t AgEq was used based on costs from mines with similar mineralization Assumed costs $45 mining, $30/tonne processing $20/tonnes G&A and recoveries of 93% for silver, 90% for gold, 94% for both lead and zinc.
- Average density values were assigned per zone based on 256 samples analysed by ALS in Zacatecas, Mexico.
- Inverse Distance Squared (ID2) interpolation was utilized at for all structures. All estimates are based on a block dimension of 2 m * 10 m * 5 m and estimation search parameters determined by variography.
- The model has been depleted for historical mining and a 5m thick crown pillar.
- The Resource Estimate is categorized into indicated and inferred categories as follows:
-
- The Indicated mineral resource category is defined by areas where drill spacing is generally less than 50 metres, blocks are informed by a minimum of two drill holes, and reasonable geological and grade continuity is shown. Copala, Tajitos HW, Rosarito and San Antonio veins defined Indicated mineral resource based on drill spacing less than 30 metres.
- The Inferred mineral resource category is defined by areas where drill spacing is less than 100 metres, blocks are informed by a minimum of two drill holes, and reasonable, but not verified, geological and grade continuity is observed. Copala, Tajitos HW, Rosarito and San Antonio veins defined Inferred mineral resource based on drill spacing less than 60 metres.
- The Inferred Mineral Resource in this estimate has a lower level of confidence than that applied to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the Inferred Mineral Resource could be upgraded to an Indicated Mineral Resource with continued exploration.
- Estimates use metric units (metres, tonnes and g/t). Metal contents are presented in troy ounces (metric tonne x grade / 31.10348).
- T. Maunula & Associates Consulting Inc. is not aware of any known environmental, permitting, legal, title-related, taxation, socio-political or marketing issues, or any other relevant issue not reported in the technical report, that could materially affect the mineral resource estimate.
- Mineral resources are not mineral reserves. Mineral resources which are not mineral reserves do not have demonstrated economic viability. There has been insufficient exploration to define the inferred resources tabulated above as an indicated or measured mineral resource. There is no guarantee that any part of the mineral resources discussed herein will be converted into a mineral reserve in the future.
The Resource Estimate is centred on the western portion of Panuco, encompassing ~4.2 km of the known 75 km of cumulative vein strike in the district. The 2022 drill program aims to utilize 13 drill rigs to 1) upgrade and expand the initial project resource base and 2) test advanced exploration targets located in the west, central and east areas of the Project. Dependent on ongoing exploration success, the Company intends to publish an update to the Resource Estimate in the second half of 2022. There is no certainty that inferred mineral resources contained in the Resource Estimate will be converted to higher confidence categories through further drilling.
Discovery Costs
To date, the Company has incurred an aggregate of approximately US$24.5 million in exploration expenditures for the life of the Project. This equates to a discovery cost of approximately US$0.23 per ounce of silver equivalent for resources defined in the Resource Estimate.
More broadly, the Company has incurred an aggregate of approximately US$98.6 million in total expenditures since the Company was formed in September 2018. This includes all project acquisition costs (shares and cash), exploration costs and corporate expenditures. This equates to a total discovery cost of approximately US$0.92 per ounce of silver equivalent for resources defined in the Resource Estimate.
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.
About Vizsla Silver
Vizsla Silver is a Canadian mineral exploration and development company headquartered in Vancouver, BC, focused on advancing its flagship, 100%-owned Panuco silver-gold project located in Sinaloa, Mexico. To date, Vizsla has completed over 120,000 meters of drilling at Panuco leading to the discovery of several new high-grade veins. For 2022, Vizsla has budgeted +120,000 meters of resource/discovery-based drilling, designed to upgrade, and expand the maiden resource as well as test other high priority targets across the district.
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.

Information Concerning Estimates of Mineral Resources
The scientific and technical information in this news release was prepared in accordance with NI 43-101 which differs significantly from the requirements of the U.S. Securities and Exchange Commission (the "SEC"). The terms "measured mineral resource", "indicated mineral resource" and "inferred mineral resource" used in this video are in reference to the mining terms defined in the Canadian Institute of Mining, Metallurgy and Petroleum Standards (the "CIM Definition Standards"), which definitions have been adopted by NI 43-101. Accordingly, information contained in this video providing descriptions of our mineral deposits in accordance with NI 43-101 may not be comparable to similar information made public by other U.S. companies subject to the United States federal securities laws and the rules and regulations thereunder.
You are cautioned not to assume that any part or all of mineral resources will ever be converted into reserves. Pursuant to CIM Definition Standards, "inferred mineral resources" are that part of a mineral resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling. Such geological evidence is sufficient to imply but not verify geological and grade or quality continuity. An inferred mineral resource has a lower level of confidence than that applying to an indicated mineral resource and must not be converted to a mineral reserve. However, it is reasonably expected that the majority of inferred mineral resources could be upgraded to indicated mineral resources with continued exploration. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, except in rare cases. Investors are cautioned not to assume that all or any part of an inferred mineral resource is economically or legally mineable. Disclosure of "contained ounces" in a resource is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute "reserves" by SEC standards as in place tonnage and grade without reference to unit measures.
Canadian standards, including the CIM Definition Standards and NI 43-101, differ significantly from standards in the SEC Industry Guide 7. Effective February 25, 2019, the SEC adopted new mining disclosure rules under subpart 1300 of Regulation S-K of the United States Securities Act of 1933, as amended (the "SEC Modernization Rules"), with compliance required for the first fiscal year beginning on or after January 1, 2021. The SEC Modernization Rules replace the historical property disclosure requirements included in SEC Industry Guide 7. As a result of the adoption of the SEC Modernization Rules, the SEC now recognizes estimates of "measured mineral resources", "indicated mineral resources" and "inferred mineral resources". Information regarding mineral resources contained or referenced in this video may not be comparable to similar information made public by companies that report according to U.S. standards. While the SEC Modernization Rules are purported to be "substantially similar" to the CIM Definition Standards, readers are cautioned that there are differences between the SEC Modernization Rules and the CIM Definitions Standards. Accordingly, there is no assurance any mineral resources that the Company may report as "measured mineral resources", "indicated mineral resources" and "inferred mineral resources" under NI 43-101 would be the same had the Company prepared the resource estimates under the standards adopted under the SEC Modernization Rules.
