# KOOTENAY REPORTS DRILL RESULTS AS 60,000-METER COLUMBA PROGRAM ADVANCES Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/kootenay-reports-drill-results-as-60-000-meter-columba-program-advances--8c11f3f6-24b5-4ecb-a609-1673c629baa7 Original source: https://orestocks.com/company/KTN.V/press-releases/4974962645548363 Publisher: orestocks Original announcement: 2026-09-16T13:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: 2026-09-16T14:22:03.078Z Atlas analysis updated: 2026-09-16T14:22:03.078Z - Company: Kootenay Silver Inc. - Ticker: KTN.V - Exchange: Unavailable - Region: Chihuahua, Mexico - Primary commodity: Silver - Secondary commodities: Lead, Zinc, Gold - Document categories: Drill results, Resource update - Extracted: 2026-09-16 14:22:03 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary Kootenay Silver Inc. reports high-grade silver drill results from its 60,000-meter Columba program in Chihuahua, Mexico, with several intercepts exceeding 500 g/t silver, including a bonanza grade of 1,580 g/t silver. The program has successfully expanded the D Vein to over 1,320 meters of strike and 600 meters depth, and identified new blind vein targets. The company confirms detailed QA/QC procedures and is fully funded for the ongoing exploration campaign, building on a maiden inferred resource of 54.1 million ounces of silver. Reasoning: The drill results demonstrate significant high-grade silver mineralization and successful expansion of known vein systems, along with the discovery of new targets. The program is well-funded and supported by robust QA/QC. The only minor drawback is the early-stage nature of the existing resource. - Positive factor: Multiple high-grade silver intercepts, including bonanza grades up to 1,580 g/t Ag. - Positive factor: Significant expansion of the D Vein's strike length \(1,320m\) and vertical depth \(600m\). - Positive factor: Identification of new blind vein targets, indicating further exploration potential. - Positive factor: Detailed QA/QC procedures and QP sign-off enhance data credibility. - Positive factor: Company is fully funded for the ongoing 60,000-meter drill program. - Negative factor: The previously announced resource estimate is entirely in the Inferred category, which is the lowest confidence level. Low confidence — this extraction should be reviewed alongside the original source.

It is also a historical reference. - Positive factor: Establishes a significant silver resource base for the project. - Positive factor: Compliant with NI 43-101 reporting standards. - Negative factor: The entire resource is in the Inferred category, indicating lower geological confidence. - Negative factor: This is a historical estimate, not new information in this release. Evidence · text > The Columba maiden inferred Mineral Resource Estimate totals 54.1 million ounces of silver contained in 5.92 million tonnes grading 284 g/t silver \(see news release dated June 17, 2025\) #### Tags used in scoring **Inferred Resource** Polarity: negative Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone. Why it applies: category is "inferred" **Cut-off Undisclosed** Polarity: negative Definition: High-grade interval reported without stating the cut-off grade used for compositing. Why it applies: no cutoff\_grade was stated **QP/CP Signed** Polarity: positive Definition: Qualified Person \(QP\) or Competent Person \(CP\) named and signed off — a member of a recognized professional association \(e.g., AusIMM, SME, AIG, P.Geo\) with relevant experience. Why it applies: qp\_signed is true **NI 43-101 Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard. Why it applies: reporting\_standards includes ni\_43\_101 ## How Atlas produces this analysis Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. 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.
