# Columba drilling returns 10 meters of 503 gpt silver, 0.1% lead, 0.6% zinc and 9.88 meters of 319 gpt silver, 0.1% lead and 0.6% zinc from the Columba Drill Program Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/columba-drilling-returns-10-meters-of-503-gpt-silver-0-1-lead-0-6-zinc-and-9-88--36c09e5f-aa8d-4dea-85cb-dd4500bcfb20 Original source: https://money.tmx.com/en/quote/KTN/news/6047831618640973/columba-drilling-returns-10-meters-of-503-gpt-silver-0-1-lead-0-6-zinc-and-9-88- Publisher: tmx Original announcement: 2026-03-02T13:30:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Kootenay Silver Inc. - Ticker: KTN - Exchange: TSX - Region: Chihuahua, Mexico - Primary commodity: Silver - Secondary commodities: Lead, Zinc - Document categories: Drill results, Resource update - Extracted: 2026-09-18 06:56:50 UTC Narrative sentiment: 0.70 · Bullish ## Minestarters Atlas summary Kootenay Silver Inc. announced additional high-grade silver, lead, and zinc assay results from its Columba High-Grade Silver Project in Chihuahua, Mexico. Highlights include 10 meters of 503 gpt silver \(5.30m true width\) and 9.88 meters of 319 gpt silver \(6.08m true width\), with several bonanza-grade sub-intervals. The expansion drilling program, now extended to 60,000 meters, continues to target step-outs from known resource bodies, successfully extending mineralization at depth and along strike in the Lupe and B2 Vein systems. The project is fully funded, and QA/QC procedures are well-documented. Reasoning: The announcement reports multiple high-grade silver intercepts, including bonanza grades, with associated lead and zinc. The drilling is explicitly described as expansion drilling, successfully extending known mineralization at depth and along strike, which is a strong positive for a project with an existing Inferred resource. QA/QC is well-documented, enhancing confidence in the results. The project is fully funded for the current drill campaign. While some intercepts are narrow, the high grades and true width disclosures are positive. The existing resource is still Inferred, which is typical for this stage but limits immediate economic confidence. - Positive factor: High-grade silver intercepts, including bonanza grades over narrow widths. - Positive factor: Significant true width reported for key intercepts. - Positive factor: Expansion drilling successfully extends mineralization along strike and to depth. - Positive factor: QA/QC procedures are well-documented, including certified labs and QP sign-off. - Positive factor: Project is fully funded for the current drill campaign. - Negative factor: Some intercepts are narrow, requiring high grades to be economic. - Negative factor: The MRE is currently entirely Inferred, indicating early-stage confidence. Low confidence — this extraction should be reviewed alongside the original source.

While the contained silver is significant, the Inferred category means it cannot be used for definitive economic studies without further drilling and upgrade. - Positive factor: Significant contained metal for an early-stage project. - Negative factor: Resource is entirely Inferred, limiting confidence for economic studies. - Negative factor: This is a historical estimate, not new information. Evidence · text > These known resource bodies currently host an inferred Mineral Resource Estimate \("MRE"\) totaling 54.1 Moz of silver based 5.92 Mt at a grade of 284 gpt \(see News Release June 17, 2025\). #### 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.
