## Minestarters Atlas summary

Chibougamau Independent Mines reported significant drill results from the Berrigan Mine project in Quebec, highlighting high-grade zinc-equivalent intercepts in the new Berrigan Deep zone. The drilling, conducted by TomaGold, successfully intersected mineralization at depth, including a 98.5 m intercept with 5.75% ZnEq.

Reasoning: Strong ZnEq and AuEq intercepts in the Berrigan Deep zone demonstrate successful step-out drilling to depth.

- Positive factor: high-grade ZnEq intercepts

- Positive factor: extension of mineralization at depth

- Positive factor: systematic mineralization observed

- Negative factor: true width is only an estimate \(80-85% of core length\)

Facts used in scoring: 30

## Classification and evidence

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: Drilling was designed to test the Berrigan Deep zone, extending beyond historical shallower mineralization.

Evidence · text

> designed to test the core of modelled conductive plates at depth and evaluate the potential of the Berrigan Deep zone

**QA/QC Disclosed**

Polarity: positive

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

Why it applies: The release mentions a Qualified Person \(QP\) sign-off and provides detailed basis for grade calculations.

Evidence · text

> This press release was written by Jack Stoch, P. Geo., ... in his capacity as a Qualified Person \(Q.P.\)

**Apparent Width Only**

Polarity: negative

Definition: Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness.

Why it applies: The document explicitly states that true width is only an estimate \(80-85% of core length\).

Evidence · text

> True width is estimated to be approximately 80-85% of the core length

## 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.
