## Minestarters Atlas summary

Kootenay Silver Inc. reported new drill results from expansion drilling at its Columba High-Grade Silver Project in Mexico, focusing on the Lupe Vein. Highlights include 84.45 meters at 94 gpt silver \(57.43m true width\) and 6.02 meters at 759 gpt silver \(3.01m true width\), with bonanza grades up to 4,040 gpt silver. The drilling has expanded the Lupe Vein system to 520 meters of strike and 450 meters of vertical extent, and it remains open for further expansion.

Reasoning: Kootenay Silver reported multiple high-grade and broad silver intercepts, including bonanza grades, from expansion drilling at its Columba project. These results significantly extend the known mineralization of the Lupe Vein system, which remains open, and represent a substantial improvement over previous best results for silver and lead. The release includes detailed QA/QC and QP sign-off, although gold assays are pending.

- Positive factor: High-grade silver intercepts, including bonanza grades up to 4,040 gpt Ag.

- Positive factor: Broad mineralized zones, with one intercept of 84.45m at 94 gpt Ag.

- Positive factor: Expansion of the Lupe Vein system along strike and to depth, which remains open.

- Positive factor: True width estimates provided for all significant intercepts.

- Positive factor: Detailed QA/QC procedures disclosed, including certified lab and QP sign-off.

- Positive factor: Significant improvement over prior best grade and grade x metres for silver and lead.

- Negative factor: Gold assay results are outstanding, so the full economic potential of the intercepts is not yet known.

- Negative factor: The referenced maiden Mineral Resource Estimate is over a year old, raising concerns about data currency.

Reasoning: This intercept shows a strong silver grade over a significant width in the D Vein system, indicating good potential and contributing positively to the project's overall resource.

- Positive factor: Strong silver grade \(261 gpt Ag\) over a good width \(23.63m\).

- Positive factor: True width \(8.51m\) confirms significant mineralization.

- Positive factor: Grade is above the prior average for silver \(286.875 gpt\) when considering the width.

Reasoning: This very high-grade silver intercept, despite its narrow width, indicates bonanza-style mineralization within the D Vein system, which is a strong positive for the project's potential.

- Positive factor: Exceptional silver grade \(1,425 gpt Ag\) well above the 500 gpt threshold.

- Positive factor: True width \(0.19m\) confirms the presence of high-grade mineralization.

- Negative factor: Very narrow intercept length \(0.52m\).

- Negative factor: Gold assays are pending, limiting the full economic assessment.

Reasoning: This intercept shows a strong silver grade over a significant width in the Lupe Vein, indicating good potential and contributing positively to the project's overall resource.

- Positive factor: Strong silver grade \(250 gpt Ag\) over a good width \(11.00m\).

- Positive factor: True width \(5.94m\) confirms significant mineralization.

- Negative factor: Gold assays are pending, limiting the full economic assessment.

#### Tags used in scoring

**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

#### Rejected tags

**True Width Disclosed** — Rejected; excluded from scoring

Polarity: positive

Definition: Actual thickness perpendicular to structure is stated, not just downhole length.

Reason: The document explicitly states '5.94m estimated true width \(etw\)' for this intercept.

Evidence · text

> 5.94

**Step-Out Extension** — Rejected; excluded from scoring

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Reason: The drilling is described as 'expansion drilling along the Lupe Vein' and 'extension and expansion drilling targets'.

Evidence · text

> expansion drilling along the Lupe Vein

**QA/QC Disclosed** — Rejected; excluded from scoring

Polarity: positive

Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\).

Reason: The release includes a detailed 'Sampling and QA/QC at Columba' section, mentioning ALS Minerals, blanks, standards, and duplicates.

Evidence · text

> All technical information for the Columba exploration program is obtained and reported under a formal quality assurance and quality control \("QA/QC"\) program.

**QP/CP Signed** — Rejected; excluded from scoring

Polarity: positive

Story-specific tag

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.

Reason: Mr. Dale Brittliffe, BSc., P.Geol., Vice President, Exploration of Kootenay Silver, is named as the Qualified Person.

Evidence · text

> Mr. Dale Brittliffe, BSc., P.Geol., Vice President, Exploration of Kootenay Silver and the Company's nominated Qualified Person pursuant to 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.
