Recent Company History

Over recent months, Vizsla Silver has focused on building out its leadership team and advancing the Panuco silver-gold project. Appointments to technical services, government relations, and corporate secretary roles, plus awarding EPCM and mine design contracts, all support a transition toward potential production. However, four of the last five largely positive or constructive announcements saw negative next‑day price reactions, suggesting the market has often faded good news while the company executes on its development plans.

6 terms

ni 43-101 mineral resource regulatory

"delivered the company's maiden NI 43-101 Mineral Resource."

A NI 43-101 mineral resource is a regulated, written estimate of how much metal or mineral is in the ground at a mining property, prepared under Canadian rules and verified by a qualified geologist or engineer. For investors it acts like an independently checked map and recipe — clarifying the size, quality and confidence level of the deposit so buyers and shareholders can compare projects and judge risk more reliably.

certified professional geologist technical

"He is a Certified Professional Geologist (CPG) by the American Institute"

A certified professional geologist is a licensed, experienced geoscientist whose training and work history have been reviewed and approved by a recognized professional board to prepare and sign technical reports about rocks, soils, groundwater, mineral resources, and geological risks. For investors, a CPG is like a licensed home inspector: their certification boosts confidence in estimates of mineral reserves, environmental liabilities and site safety, helping reduce the chance of costly surprises.

cpg technical

"Certified Professional Geologist (CPG) by the American Institute"

Consumer packaged goods are everyday items people buy frequently and replace often, such as food, personal care products, and household cleaners. Investors watch CPG businesses because they tend to produce steady, repeatable sales and reveal how well a company keeps customers and controls costs; small shifts in consumer habits, pricing or supply chain costs can quickly affect revenue and profit. Think of a CPG company as a neighborhood store supplying staples—tiny changes in demand or cost ripple across its earnings.

qualified person regulatory

"and a Qualified Person as defined by National Instrument 43-101."

A qualified person is someone with specialized knowledge, experience, and training in a particular field, allowing them to accurately assess and verify information or work. Their expertise helps ensure that reports, evaluations, or decisions are trustworthy and meet required standards. For investors, a qualified person provides confidence that the information they rely on is credible and properly validated.

epithermal vein system technical

"discovery of the high-grade Switchback epithermal vein system at Gold"

An epithermal vein system is a network of mineral-filled fractures formed near the Earth’s surface when hot, mineral-rich fluids moved through cracks and deposited metals like gold and silver. For investors, these systems are significant because they can concentrate valuable metals in accessible, mineable zones—think of them as nature’s plumbing that sometimes leaves metal-rich veins, making them prime targets for exploration and potential mining projects.

esg technical

"committed to responsible mining, ESG principles, environmental stewardship"

ESG stands for Environmental, Social, and Governance, which are key factors investors consider when evaluating how sustainable and responsible a company is. It involves assessing how a company manages its impact on the environment, treats its employees and communities, and operates transparently and ethically. Investors use ESG criteria to identify businesses that align with their values and have the potential for long-term success.

"What Jesus has helped to build at Panuco over the past four years is remarkable, and we're just getting started," stated Michael Konnert, President and CEO. "From the Napoleon and Copala discoveries through to a completed Feasibility Study and the development milestones we are now executing, he has guided Vizsla Silver through its transition from discovery-stage exploration toward development readiness, and his promotion to Chief Geologist is a reflection of that contribution and ensures that his expertise remains central to the project as we advance toward production. Additionally, appointing Guillermo bolsters our already strong technical team. His experience in high-grade Latin American silver and gold systems and track record of delivering resources make him exactly the right person to lead our exploration program into its next chapter."

Dr. Velador, Chief Geologist, comments, "Guillermo's technical depth, strategic instinct, and experience with high-grade silver deposits are exactly what this district calls for. His background across discovery, resource definition, and development transition is directly applicable to not only where Panuco stands today, but also where we intend to take it over the coming years. The district's exploration upside remains substantial, and I look forward to moving ahead with our strengthened team as we continue to unlock it."

He joins Vizsla Silver from Outcrop Silver & Gold, where as Vice President, Exploration, he led technical and strategic exploration at the Santa Ana project in Colombia and delivered the company's maiden NI 43-101 Mineral Resource. Prior to Outcrop, Mr. Hernandez served as Senior General Geology Supervisor at Lundin Gold's Fruta del Norte mine in Ecuador, contributing to resource conversion programs that added 1.2 million ounces of gold in new resources.
