## Minestarters Atlas summary

Coast Copper is highlighting historical 2012 drill results from the Miya Vein at its Sweeney Silver Project. The company notes that these results are historical and have not been verified by their current Qualified Person.

Reasoning: The document is a highlight of historical 2012 drill results rather than new assay results. The intercepts lack true width disclosures and the company explicitly states the historical information has not been verified by their current QP.

- Negative factor: Stale data re-release

- Negative factor: Apparent width only

- Negative factor: No QA/QC disclosure for these specific results

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

Facts used in scoring: 37

## Classification and evidence

**Stale Data Re-release**

Polarity: negative

Definition: Historical results re-announced with no new assays or reinterpretation — low genuine novelty.

Why it applies: The document highlights 2012 drill results as part of a 2026 announcement.

Evidence · text

> 2012 drill program covered 350 m of strike length and highlighted drill results include

**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 there is insufficient information to determine true widths.

Evidence · text

> There is insufficient geological information available to determine true widths of mineralization.

**No QA/QC Disclosure**

Polarity: negative

Definition: Release does not disclose QA/QC — lab certification, CP/QP sign-off and assay protocols cannot be checked from this document.

Why it applies: The release does not provide QA/QC protocols for the 2012 historical data being highlighted.

Evidence · text

> Historical information provided cannot be relied upon as the Company's QP as defined under NI 43-101 has not prepared nor verified the historical information.

## 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.
