## Minestarters Atlas summary

Kootenay Silver announced a positive Preliminary Economic Assessment \(PEA\) for its La Cigarra Silver Project in Chihuahua, Mexico, outlining a US$763 million after-tax NPV \(5%\) and a 41% after-tax IRR. The PEA projects a 14-year open-pit mine life with 63.7 million ounces of payable silver production and a rapid 1.9-year payback period. The study is based on an updated Mineral Resource Estimate with 23.02 Mt Measured and Indicated resources grading 81 g/t AgEq, and 6.78 Mt Inferred resources grading 90 g/t AgEq.

Reasoning: Kootenay Silver's PEA for the La Cigarra Silver Project demonstrates robust economics with a US$763 million after-tax NPV and 41% IRR, supported by a 14-year mine life and substantial silver production. The underlying resource estimate shows high confidence with 77.2% M&amp;I. However, the study is preliminary, includes Inferred resources, and lacks full transparency on some economic assumptions and permitting status.

- Positive factor: Strong after-tax NPV and IRR for a PEA-stage project

- Positive factor: Rapid payback period of 1.9 years

- Positive factor: Long mine life of 14 years

- Positive factor: Significant payable silver production profile

- Positive factor: High M&amp;I confidence in the underlying resource estimate

- Positive factor: Project located in a well-established mining district with existing infrastructure

- Positive factor: PEA and MRE prepared by Qualified Persons under NI 43-101 standards

- Negative factor: Preliminary Economic Assessment \(PEA\) is conceptual and includes Inferred Mineral Resources

- Negative factor: No Mineral Reserves have been demonstrated

- Negative factor: IRR and price deck basis \(real/nominal\) are undisclosed, limiting comparability

- Negative factor: High average strip ratio of 8.0:1

- Negative factor: Permitting is still in progress

- Negative factor: Closure funding mechanism is undisclosed

- Negative factor: No explicit sensitivity analysis for key economic variables disclosed

Low confidence — this extraction should be reviewed alongside the original source.

Reasoning: The Inferred silver equivalent resource adds potential upside but carries a lower level of confidence, requiring further exploration to upgrade to higher categories before it can be fully relied upon for economic studies, with assumptions for the equivalent grade disclosed.

- Positive factor: Resource estimate is NI 43-101 compliant and QP signed

- Positive factor: Silver equivalent grade of 90 g/t AgEq is economic

- Negative factor: Inferred resource category has a lower level of confidence and cannot support economic studies alone

#### 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: The resource is classified as Inferred, which is a speculative category with limited drilling.

Evidence · table

> Inferred

Context: Inferred

**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: The MRE is part of the PEA which was reviewed and approved by Qualified Persons.

Evidence · text

> Allan Armitage \(PhD. P.Geo.\), SGS Canada Inc. Geological Services

**NI 43-101 Compliant**

Polarity: positive

Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard.

Why it applies: The MRE is consistent with CIM Definition Standards and forms the basis for an NI 43-101 compliant PEA.

Evidence · text

> The classification of the current MRE into Measured, Indicated, and Inferred is consistent with current CIM Definition Standards For Mineral Resources and Mineral Reserves \(CIM, 2014\).

**Resource Update**

Polarity: neutral

Definition: Revised estimate for an existing resource — compare to prior to assess progress.

Why it applies: The document refers to this as an 'updated Project Mineral Resource estimate'.

Evidence · text

> The updated Project Mineral Resource estimate \("MRE"\) \(Table 1\) forms the basis of the PEA.

**Cut-off Disclosed**

Polarity: positive

Definition: Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.

Why it applies: cutoff\_grade is stated

**PEA-Supporting**

Polarity: neutral

Definition: Resource estimate prepared to support a Preliminary Economic Assessment — early-stage study.

Why it applies: the release names the study this estimate supports

**PFS-Supporting**

Polarity: neutral

Definition: Resource estimate prepared to support a Pre-Feasibility Study — requires adequate M&amp;I component.

Why it applies: the release names the study this estimate supports

**DFS-Supporting**

Polarity: neutral

Definition: Resource estimate prepared to support a Definitive Feasibility Study — requires high M&amp;I confidence.

Why it applies: the release names the study this estimate supports

## 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.
