After-Tax NPV (5%) of US$1,802 million, After-Tax IRR of 111%, Initial Costs of US$173 million, Average Annual Production of 17.4 million oz AgEq at AISC of US$10.61 per oz AgEq

Vizsla Silver Corp. (TSX: VZLA) (NYSE: VZLA) (Frankfurt: 0G3) is pleased to announce positive results from its independent Feasibility Study on its 100%-owned flagship Panuco silver-gold project located in Mexico.

The Feasibility Study, completed by Ausenco Engineering Canada ULC supported by Mining Plus Canada Consulting Ltd. and SGS Canada Inc. provides a robust case for developing the Panuco silver-gold project as a high-margin, underground precious metals mine with low initial capital requirements and rapid payback. The Company is advancing permitting and project financing initiatives, targeting a construction decision upon receipt of required approvals.

“The strength of the Feasibility Study reflects the technical excellence and commitment of the Vizsla Silver team and all of our consultants,” stated Simon Cmrlec, COO of Vizsla Silver. “The engineering and procurement for the project was significantly advanced during the Feasibility Study, which coupled with the actual performance of the ongoing test mine provides confidence in the results of the study. Project CAPEX and OPEX remain in line with the PEA, and the study demonstrates the project will produce more than 20 million silver equivalent ounces annually over the first five years, averaging 17.4 million ounces over the life of the project, significantly exceeding the production profile outlined in the PEA.”

“We are very pleased to deliver a robust Feasibility Study on the Panuco project, outlining a high-margin, low CAPEX, silver focused precious metals operation”, stated Michael Konnert, President and CEO of Vizsla Silver. “The study builds upon the strong economics outlined in the Panuco PEA, published in the summer of 2024, indicating that Panuco can become the next large-scale silver-primary producer in Mexico. Applying the updated, higher-grade resource estimate published in January 2025, production output in the Feasibility Study has increased significantly in the early years of the mine life relative to the PEA. This, combined with improved commodity price assumptions, demonstrates a base case after tax NPV (5%) of US$1.8 billion, an IRR of 111%, and a seven-month payback period at US$35.50 per ounce silver and US$3,100 per ounce gold. We expect to continue advancing both our underground and surface exploration proximal to the ongoing test mine to further grow the scale and quality of the deposit. Vizsla Silver would like to thank all its employees, community members and consultants/contractors including Ausenco, Mining Plus, SGS, SACH and PWC for their continued hard work in supporting our project. This very important milestone represents a key inflection point for the Company, the Panuco asset and all of our stakeholders as we advance towards production targeted for the second half of 2027.”

Feasibility Study Overview

The 2025 Panuco Feasibility Study considers two contiguous underground mines, the Copala Mine and the Napoleon Mine, with on-site treatment of the mined material processed through a 3-stage crushing-grinding circuit, along with a leach and Merrill Crowe circuit to produce silver-gold doré bars. The mines will be contractor-operated, utilizing ramp-access and a combination of long-hole stoping and drift-and-fill mining methods.

The processing throughput capacity of 3,300 tonnes per day for the first 3 years, expanding to 4,000 tonnes per day in year 4, results in an initial mine life of 9.4 years. The Feasibility Study leverages the Panuco district’s existing infrastructure in a well-established mining jurisdiction, including all-weather access roads, high-voltage power, and an abundance of water and skilled labour.

The Feasibility Study is derived using the Company’s updated NI 43-101 Mineral Resource Estimate (dated February 20, 2025). The effective date of the Feasibility Study is November 4^th, 2025, and an NI 43-101 compliant technical report on the Feasibility Study will be filed on the Company’s website and SEDAR+ within 45 days of this disclosure.

Capital and Operating Costs

The pre-production initial CAPEX is estimated to be $238.7 million, with a net initial cost of $173 million after accounting for $127.7 million in pre-production revenues and $62 million pre-production costs. Initial CAPEX includes a contingency of $24 million. Cumulative sustaining capital is estimated at $287.3 million. LOM operating costs for the Panuco Project are estimated to average $85.11 per tonne processed.

Sustaining Capital is expected to average approximately $30.72 million per year, largely attributable to continual mine development. In Year 4, with the mill expansion and increase in underground development associated with accessing the Napoleon Area veins, an expansion cost of $15.4 million is added (to be funded through initial cash flows). The projected timing of increases in capital expenditures in year 3 may be pushed further into the future with continued exploration success along the Copala structure.

The Feasibility Study is based on contractor underground mining, which has an estimated LOM cost of $53.31 per tonne milled. Processing costs are estimated at $24.84 per tonne milled, which includes TSF handlings of $0.33 per tonne milled. G&A costs are estimated at $6.96 per tonne milled.

The capital and operating cost estimate was developed in Q4 2025 United States Dollars (US$). The capital cost summary is presented in Table 8, and the operating cost summary is presented in Table 9.

Mining

The Panuco Project is a collection of silver-gold deposits located in the Panuco mining district in Sinaloa, Mexico, with Mineral Reserves that extend from surface to over 600 m in depth. The deposits range in thickness from 1.5 m to greater than 20 m.

Based on the characteristics of the deposit, long-hole stoping was selected as the primary mining method for all deposits, with drift-and-fill selected for the northern portion of the Copala North Zone, which is located directly under the Copala township. A sublevel spacing between 15-20 m was selected with stope strike lengths of 20 m for LHS to be used dependant on prevailing ground conditions, and 5 m high DAF drifts (three lifts per sublevel).

The mining methods considered for the Panuco Project are proposed to use a combination of cemented rock backfill, uncemented rock backfill, and paste backfill for stope support.

For the feasibility design of the Panuco Project, planned dilution and unplanned rock dilution (ELOS) was accounted for using the Deswik Stope Optimizer®. Dilution within SO outputs was estimated at 36% and additional unplanned dilution of 2% was added for backfill dilution in longhole stopes. Internal dilution in DAF mining within the mining shape was estimated at 31% and additional backfill dilution in DAF was estimated at 5%. Mining recovery averaging 94% was applied for LHS based on geometry and extraction sequence, and a mining recovery of 100% was applied for DAF as a factor to the shapes created by SO within the production schedule. Figure 1 shows the proposed stope shapes by NSR ($US/t) and development design for the Panuco Project.

A Net Smelter Return (NSR) model was used to estimate the revenue of the mineralized material. Interim process recoveries, doré grades, smelting and refining terms, royalties and transportation costs were assumed to determine the NSR value. A Cut-Off Value was used to flag material by whether the revenue in a block exceeds the costs of extraction and processing of that block. Following the financial model completion, there were three COVs used to assess mining at Panuco: A Fully Costed COV, an Incremental COV and the Marginal COV.

The Fully Costed COV represents the break-even value of Mineral Reserve required to cover all the associated operating and sustaining capital costs of extraction and processing. Fully costed COVs were initially assumed for Panuco at US$100.00/t for LHS and US$120.00/t for DAF. Following the completion of the financial model, the Fully Costed COV was calculated at US$105.72 for LHS and US$129.33/t for DAF.

The Incremental COV of US$ 87.00 /t for LHS and US$ 110.00 /t for DAF was applied in areas where development had already been completed, and no additional capital was required to access new stoping blocks. The Incremental COV includes the assumption that the material value exceeds the costs of the operational costs which include mining, processing and G&A, and does not include sustaining capital costs. The Incremental COV applied was elevated slightly compared to the calculated costs to reduce the effect of near cut-off stoping material and improve the overall mining sequence. Less than 1% of the AgEq ounces attributed to LHS and less than 2% of the AgEq ounces attributed to DAF are between the Incremental COV and the Fully Costed COV.

The Marginal COV of US$33.00/t was applied to development when the operation has committed to the preparation of stoping or DAF blocks and the material must be mined in order to access a production area. The Marginal COV includes the assumption that the material value exceeds the costs of the incremental processing and G&A and does not include any operational mining or sustaining capital costs. The Marginal COV applied was elevated slightly when compared to the calculated cost to remove the risk of overstating marginal tonnes in the Mineral Reserve.

Due to the distance between the various geological deposits, the project is separated into two underground mines. The Copala Mine, the larger of the two, accesses the Copala, Cristiano, and Tajitos deposits. The Napoleon Mine portal, located approximately 800 m west of the Copala Mine portal, accesses the Napoleon and La Luisa deposits.

Contractor mining is currently proposed for the Panuco Project to minimize upfront capital, leverage skilled labour and achieve higher productivity. The annual Panuco project material movements are summarized in Table 10.

Table 10: Total and Annual Material Movement Schedule for the Panuco Project

Processing and Metallurgy

Vizsla Silver has completed four rounds of metallurgical test work on the Panuco Project deposits since 2021. The latest round of test work (2025) focussed on variability within the deposit, defining consumable usage within the deposits and ensuring process efficiency was optimized.

Test work in 2025 included comminution test work, variability work on both whole ore leach and flotation flowsheets, oxygen uptake, thickening, rheology, paste characterisation and cyanide detoxification.

Based on the test work and mine plan feed grades, life-of-mine average recoveries are estimated at 92.3% Ag and 93.8% Au.

The Feasibility Study outlines a two-phase process plant design, beginning with a 3,300-tonne-per-day whole-ore leach circuit utilizing a primary grind of 50 µm. Ore will be processed through a three-stage crushing circuit, followed by grinding to 50 µm in a ball mill. The ground slurry will then enter the leach circuit for a total retention time of approximately 96 hours. Leach discharge will flow by gravity to a counter-current decantation (CCD) circuit, where solids are separated from the pregnant liquor. Pregnant liquor then reports to the Merrill Crowe and refinery circuits to produce silver-gold doré.

Phase 2, scheduled for Year 4, will expand throughput to 4,000 tonnes per day and increase the primary grind size to 70 µm, incorporating a flotation and regrind circuit between the ball-mill discharge and leach feed. The additional circuit enables a coarser primary grind, improves overall metal recovery, and optimizes power and reagent efficiency. Flotation concentrate, which contains a high proportion of gold, will be treated in a high intensity grinding mill and reduced to 20 µm. Ground concentrate is then leached separately from the flotation tailings and then fed into the tailings leach circuit with the tailings to maximize metal recovery.

Infrastructure

Access to the Panuco Project is planned via Highway 40 through the expansion of an existing entryway, incorporating traffic control measures to ensure safe entry and exit from the site. Existing site roads will be upgraded, and community access routes will remain open and safely distanced from active mining areas.

Electrical power for the project will be sourced from a 230 kV transmission line that traverses the property. Vizsla plans to construct an on-site switching substation adjacent to the process plant (the project’s largest power consumer) and distribute electricity at 13 kV throughout the site as needed.

Underground dewatering will serve as the primary water source for the project. Vizsla intends to reuse and recycle as much water as possible and has developed a water management plan where the wet season excess water can be stored for process use during drier months.

Tailings from the process plant will be piped to the tailings storage facility (TSF) which follows the access road. The TSF is designed as a centreline raise embankment with 4 stages throughout the project life.

The Feasibility Study envisages a stockpile of ore created ahead of commissioning the process plant. This approach reduces project start-up risk and supports consistent grade control during commissioning and early operations. The pre-production stockpile is estimated to total approximately 523,000 tonnes, providing a buffer equivalent to five months of process plant feed.

Permitting & Environmental

The project currently operates under mine exploration permits granted in 2020 and 2021 by SEMARNAT (the Secretariat of Environment and Natural Resources). An active Informe Preventivo (IP) covers the Panuco Project area, authorizing ongoing drilling and exploration activities. All activities related to the Test Mine are authorized under existing permits.

The construction and operation phases of the project require several additional environmental permits. Applications for the Environmental Impact Assessment (EIA) and the corresponding Risk Assessment were submitted in the first quarter of 2025 and are currently under review by SEMARNAT. In parallel, the preparation of technical documentation for the Land Use Change is in progress. Additional permits required for project development include a construction permit from the local municipality, and explosives permit from the Ministry of Defense.

The baseline environmental information collected to date has been largely presented in reports commissioned to support the submission of an Environmental Impact Assessment (MIA in Mexico) that was submitted to SEMARNAT in February 2025. Baseline data available includes, meteorology and climate, surface water, groundwater, air quality, noise, soil, and flora and fauna. Future studies will need to be initiated and/or further advanced to support the next phase of the project design in the areas of geochemistry studies, and further refinement of the mine water balance.

Regarding communities, Vizsla Silver has negotiated operating agreements with all five Ejidos in the greater Panuco area (Copala, Pánuco, San Miguel del Carrizal, El Habal de Copala, and Platanar de los Ontiveros). The operating agreements cover exploration, construction, operation, and closure phases for a 30-year period. The Social Impact Assessment and Social Baseline Update are ongoing and scheduled for completion in the first quarter of 2026.

Project Enhancement Opportunities

The Feasibility Study does not incorporate any inferred resources; however, opportunities exist across all deposit areas to upgrade inferred material to indicated or measured categories, particularly once underground drilling can be conducted from optimized collar locations, reducing drill costs and improving data quality. Extending the mine life at Copala remains a key focus, given its early access to ore, strong grade profile, and suitability for whole-ore leach processing.

Metal prices applied in the Feasibility Study’s Mineral Reserve Estimate are more conservative than those used in the financial model. This creates potential to increase the contained ounces in the mine plan by converting additional Measured and Indicated Mineral Resources to Mineral Reserves by using the financial model metal prices to evaluate the inclusion of additional inventory.

Vizsla is evaluating partnerships with regional power providers that could reduce substation capital costs and support the delivery of lower-carbon electricity to the project within Mexico’s privatized power grid.
