VANCOUVER, BC, June 18, 2025 /CNW/ - Vizsla Silver Corp. (TSX: VZLA) (NYSE: VZLA) (Frankfurt: 0G3) ("Vizsla Silver" or the "Company") is pleased to provide an update on the ongoing development of its Copala test mine at its 100%-owned Panuco silver-gold project, located in Sinaloa, Mexico.
The test mine program marks a major step forward in de-risking the Panuco Project, as the Company transitions from exploration to development. The Copala portal, established as part of this program, is expected to serve as the primary access to underground mining operations following a construction decision.
"We're now testing underground at Panuco and executing the test mine development according to plan, at the historic Copala district," commented COO Simon Cmrlec. "Our crews are performing well, advancing safely, installing all required ventilation and ground support, and we are meeting planned development rates. Our team is currently focused on optimising advance rates and testing contractor capabilities.
This portal will ultimately become the main access for future mining. Every meter brings us closer to the 10,000-tonne bulk sample location and positions us for efficient resource conversion/expansion drilling from underground, and for the ultimate mine development and ramp-up. We are on track to complete the fully funded test mine program by year-end."
Test Mine Progress
Vizsla Silver has now advanced approximately 125 metres along the Copala decline. The decline is advancing in favorable ground conditions at a 15% grade with dimensions of 5.5 metres wide by 5.5 metres tall. A 10,000-tonne bulk sample will be taken from the 460 level which is approximately 70 metres vertically below the surface. The decline is currently progressing at a rate of 4 metres per day, with drilling and mucking currently being optimised to achieve two blasts per day and advance rates of around 8 metres per day.
Bulk Sampling & Technical Program
Upon reaching the ore zone, Vizsla Silver will extract a 10,000-tonne bulk sample and stockpile it on surface without impacting the environment by utilising previously disturbed areas. This material will ultimately be used for:
Paste fill and cemented rockfill (CRF) testing to support backfill planning.
Rock competency and structural consistency analysis to optimize mine design and cost models related to support requirements.
Grade reconciliation with the block model.
Technical Observations & Future Opportunities
The Copala test mine portal is situated approximately 300 metres north of the proposed processing facility. Waste stockpiles and ore staging areas are located within 200 metres of the portal, with all current activities using existing roads and confined to previously disturbed areas from historic mining.
Underground access will enable low-cost drilling from underground stations, supporting the conversion of existing resources to higher-confidence categories. Several high-priority targets have already been outlined and are expected to be tested as the decline advances.
Mapped parallel structures on the surface highlight near-mine exploration upside.
The onsite workforce continues to grow, with an emphasis on hiring from the local community. Newly constructed infrastructure – including first aid facilities, staff buildings, and workshops – not only supports operational efficiency, but also enhances safety protocols and emergency response capabilities.
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 7,189.5-hectare, past producing district benefits from over 86 kilometres of total vein extent, 35 kilometres of underground mines, 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.
On January 6, 2025, the Company announced an updated mineral resource estimate for Panuco which includes an estimated in-situ combined measured and indicated mineral resource of 222.4 Moz AgEq and an in-situ inferred resource of 138.7 Moz AgEq (please refer to Vizsla's press release dated January 6, 2025).

Quality Assurance / Quality Control
Drill core 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 and rock samples were shipped to SGS Lab in Durango Mexico for sample preparation and analysis. The ALS Zacatecas, North Vancouver facilities and SGS lab 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.
Qualified Person
In accordance with NI 43-101, Jesus Velador, Ph.D., MMSA QP, Vice President of Exploration, is the Qualified Person for the Company and has reviewed and approved the technical and scientific content of this news release.
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 herein 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 herein 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 herein 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.
