The PEA outlines a 14-year open-pit operation with average annual payable silver production of 4.55 million ounces. The study is based on an updated Mineral Resource Estimate \(MRE\) effective April 4, 2026, which includes Measured, Indicated, and Inferred resources, with a significant portion of Inferred material. The company plans to advance the project through resource expansion, engineering optimization, and permitting. Reasoning: Kootenay Silver announced a positive PEA for its La Cigarra Silver Project, demonstrating robust economics with a 41% post-tax IRR and a 1.9-year payback. The study is supported by an updated Mineral Resource Estimate, but its preliminary nature and reliance on Inferred resources, coupled with undisclosed economic conventions and theoretical metallurgical assumptions, introduce some uncertainty. - Positive factor: Positive PEA results with strong economics \(high IRR, fast payback, significant NPV\) - Positive factor: Updated Mineral Resource Estimate provides a solid foundation for the project - Positive factor: Project located in a well-established mining district with existing infrastructure - Positive factor: Identified upside opportunities for resource expansion and optimization - Positive factor: QP sign-off for both PEA and MRE - Negative factor: PEA is preliminary in nature and includes a significant portion of Inferred Mineral Resources - Negative factor: Several key economic conventions \(IRR basis, payback basis, price deck basis, cost basis\) are undisclosed - Negative factor: Metallurgical recoveries used in the AgEq calculation are theoretical assumptions, not actual test results, and some are relatively low \(Au, Zn\) - Negative factor: Project is not yet fully permitted - Negative factor: Unusual LOM closure and reclamation cost as a credit Low confidence — this extraction should be reviewed alongside the original source. Facts used in scoring: 29 ## Classification and evidence **Cut-off Disclosed** Polarity: positive Definition: Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison. Why it applies: A current resource fact retains the disclosed cut-off grade **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: the document describes a flotation route \("flotation"\) **Theoretical Recovery Only** Polarity: negative Definition: Only theoretical or liberation-derived recovery reported, with no actual test result. Why it applies: The disclosure includes a theoretical recovery figure, distinct from actual test results **Multi-Domain Tested** Polarity: positive Definition: Variability across ore domains \(oxide, transition, fresh\) has been addressed. Why it applies: 3 distinct composites were tested ## Extracted facts Stored fact records: 27.

Sentiment reflects the extracted narrative and classification rules; it is an interpretation, not a reported measurement. Evidence quotes and context are provided where available. Missing data, low-confidence results, and review flags indicate limitations. Check the original publisher announcement before relying on an interpretation.
