Vizsla Silver files NI 43-101 tech report on Panuco

The most recent news, dated December 9, 2025, states that Vizsla Silver Corp. (TSX/NYSE: VZLA) has filed the National Instrument 43-101 Technical Report and Feasibility Study (FS) for its Panuco Silver-Gold Project in Sinaloa, Mexico. The technical report has an effective date of November 4, 2025. This filing is a procedural step following the announcement of the positive Feasibility Study results on November 12, 2025.

The key economic highlights from the filed FS, consistent with the previous announcement, are: * After-Tax Net Present Value (NPV) at a 5% discount rate: US$1,802 million. * Internal Rate of Return (IRR): 111%. * Initial Capital Cost: US$173 million. * Average Annual Production: 17.4 million ounces Silver Equivalent (AgEq). * All-in Sustaining Cost (AISC): US$10.61 per ounce AgEq. * Initial Mine Life: 9.4 years. * Payback Period: 7 months. * Base Case Metal Price Assumptions: Silver at US$35.50/oz and Gold at US$3,100/oz.

The filing of the Feasibility Study technical report itself is a routine, albeit important, administrative step. It does not introduce new information beyond what was already announced on November 12, 2025. Therefore, the immediate material impact of this specific news release is neutral.

However, when viewed in the context of the preceding news flow, particularly the positive Feasibility Study results (November 12, 2025) and the successful closing of a US$300 million convertible senior notes offering (November 24, 2025), the company has achieved significant de-risking milestones.

Key considerations for a critical equity analyst: 1. Metal Price Sensitivity: The excellent FS economics (NPV of US$1.8B, IRR of 111%) are based on significantly higher metal price assumptions (US$35.50/oz Ag, US$3,100/oz Au) compared to the Preliminary Economic Assessment (PEA) published in July 2024 (US$26/oz Ag, US$1,975/oz Au). This substantial increase in assumed commodity prices is the primary driver for the improved economics, not necessarily underlying operational improvements. A prudent investor must assess the sustainability of these high assumed prices over the project's mine life. 2. Increased AISC: While the NPV and IRR improved, the AISC increased from US$9.40/oz AgEq (stated in the September 2025 presentation, referencing the PEA) to US$10.61/oz AgEq in the FS. This indicates higher operating costs per ounce, which is a negative, though overshadowed by the higher revenue projections due to elevated metal prices. 3. Financing Secured: The closing of the US$300 million convertible notes offering (November 24, 2025) is a material positive event. It provides substantial capital, exceeding the initial capital cost of US$173 million for the Panuco project, and replaces the previously announced Macquarie debt mandate. This significantly de-risks the funding aspect of project development. The conversion price of US$5.84 provides a buffer before dilution, but implies future dilution if the stock performs well. 4. Project Advancement: The completion and filing of the FS marks a critical technical de-risking milestone, moving the project closer to a construction decision. The CEO reiterated the company's vision to become a large-scale silver-primary producer. 5. Safety Incident & Resumption: The temporary suspension of operations in January 2025 due to a contractor fatality was a material negative event. The subsequent resumption of fieldwork and test mine operations indicates that safety protocols were addressed, and the project is back on track.

In summary, the filing of the FS report is a routine confirmation. The overall picture for Vizsla Silver, including the positive FS results (despite aggressive metal price assumptions) and the successful financing, is highly positive, positioning the company to advance Panuco towards production. However, the reliance on elevated metal prices for the impressive economics requires careful scrutiny.

Vizsla Silver Corp. is a Canadian exploration and development company focused on the Panuco silver-gold district in Sinaloa, Mexico. Its primary objective is to become a leading single-asset silver producer.

Flagship Project: The Panuco Silver-Gold Project is a 100%-owned, newly consolidated, high-grade epithermal discovery in a historic past-producing district. The project benefits from extensive existing infrastructure, including over 86 km of vein extent and 35 km of underground mine workings, roads, power, and permits.

Development Progression: * July 2024 (PEA): Preliminary Economic Assessment outlined robust economics with an After-Tax NPV(5%) of US$1.1 billion, an IRR of 86%, initial capital costs of US$224 million, and average annual production of 15.2 Moz AgEq over a 10.6-year mine life (using US$26/oz Ag, US$1,975/oz Au). * January 2025 (MRE): Updated Mineral Resource Estimate showed a 43% increase in Measured & Indicated (M&I) resources to 222.4 Moz AgEq (including 46 Moz Measured), with a 4.5% increase in average M&I grade. Inferred resources decreased to 138.7 Moz AgEq. * Q4 2024 / Q1 2025 (Test Mine): Commencement of a fully financed and permitted test mining and bulk sample program at Copala, aimed at reconciling geotechnical models, validating resource models, and gaining operational experience. * May 2025 (Santa Fe Acquisition): Acquired the Santa Fe project, immediately south of Panuco, which includes a permitted 350 tpd mill and historic production. This expands Vizsla's land package and provides potential for future production centers ("Project 2"). * November 2025 (FS): Delivered a positive Feasibility Study (FS), which significantly upgraded the project's economics to an After-Tax NPV(5%) of US$1.8 billion and an IRR of 111%, with initial capital of US$173 million, and 17.4 Moz AgEq annual production over 9.4 years. The FS used significantly higher metal price assumptions (US$35.50/oz Ag, US$3,100/oz Au) compared to the PEA. * Target Production: The company is targeting first silver production in H2 2027.
