Kootenay Silver Inc. (TSXV: KTN; OTCQX: KOOYF) reported on August 7, 2026 that it has filed the formal National Instrument 43-101 (NI 43-101) technical report for its La Cigarra Silver Project in Chihuahua, Mexico. NI 43-101 is a Canadian securities rule that governs how mining companies disclose technical and scientific information about their projects; a filed technical report is the detailed, standardized document that has to back up any headline project economics a company announces, and it has to be signed off by an independent, professionally accountable geologist or engineer known as a Qualified Person.
What This Confirms
The report supports figures Kootenay first announced on June 15, 2026: a Preliminary Economic Assessment (PEA) estimating an after-tax net present value of $763 million and an internal rate of return of 41% for La Cigarra. A PEA is an early-stage study that estimates whether a project could be economic, based on assumed costs, metal prices, and a preliminary mine plan; it’s a planning-level estimate, not a construction-ready analysis, and Kootenay has not indicated when it might move toward a more advanced feasibility study. The company said there are no material differences between the newly filed technical report and the numbers in the June release, meaning today’s filing is a formal validation step rather than an update to the economics themselves.
The distinction matters for how much weight a reader should put on these numbers. A company’s own press release presents figures the company believes in; a filed NI 43-101 report means those same figures have now been reviewed and stood behind by named, independent technical consultants who carry professional liability for the work. In this case, that includes Sacré-Davey Engineering as lead author, along with contributions from Canenco Consulting Corp., AKF Mining Services, Knight Piésold Consulting, and SGS Geological Services. The report’s Qualified Person, VP of Exploration Dale Brittliffe, is a Kootenay employee and is not independent of the company, which is standard disclosure practice, but the underlying engineering work behind the economics comes from outside consulting firms.
About the Project
La Cigarra sits about 26 kilometers from the city of Hidalgo del Parral in Chihuahua State, in a historic silver-producing region that includes the long-running Santa Bárbara and San Francisco del Oro mines. The company describes the site as benefiting from existing infrastructure, road access, nearby power, water availability, and an experienced local mining workforce, factors that typically reduce the capital cost and timeline for developing a project compared to a remote greenfield site. Kootenay says the current mine plan covers only part of a mineralized trend it has traced for more than nine kilometers across the property, meaning the company sees room to expand the resource beyond what’s captured in the current PEA.
What’s Still Ahead
A positive PEA, even one now backed by a filed technical report, is not a construction decision. Kootenay has not announced a timeline for advancing La Cigarra to feasibility study or a construction decision, and all of the project’s economics, silver price assumptions, cost estimates, and the estimated return, remain forward-looking projections rather than guaranteed outcomes.
