## Minestarters Atlas summary

Brunswick Exploration has reported a significant 302-metre-wide spodumene-bearing pegmatite interval from drill hole AN-26-17 at the Anatacau Main Project in Quebec. Visual estimates indicate approximately 30% spodumene content, extending the Anais dyke to a depth of 500 metres, with formal assays currently pending.

Reasoning: The drill hole reports an exceptionally wide pegmatite interval that extends a known dyke at depth, though actual lithium assays are still pending.

- Positive factor: exceptional width of 302m

- Positive factor: high spodumene visual estimate of 30%

- Positive factor: extension of Anais dyke to 500m depth

- Positive factor: low internal dilution \(sub 5%\)

- Negative factor: assays are pending

- Negative factor: visual estimates only for spodumene content

- Negative factor: drill rig depth capacity limitations

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

Facts used in scoring: 1

## Classification and evidence

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The intercept extends the Anais dyke to a vertical depth of 500 metres and expands the system.

Evidence · text

> extends the Anais dyke to a vertical depth of 500 metres

**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 industry-standard QA/QC procedures and names Agat Laboratories for analytical work.

Evidence · text

> applying industry-standard QA/QC procedures to its drilling and prospecting programs

**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 302m interval is a downhole width and the true width is only provided as an estimate \(78-80% of interval\).

Evidence · text

> true thickness of the Anais dyke is estimated at approximately 78% to 80% of the 302-metre interval

#### Tags used in scoring

**QA/QC Disclosed**

Polarity: positive

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

## 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.
