## Minestarters Atlas summary

Bell Copper reports that drilling at the Big Sandy Porphyry Copper Project has reached 1200m in hole BS-4, though progress has been slowed by drilling challenges. The hole is targeting porphyry bedrock and has encountered visual evidence of native copper and chalcocite clasts.

Reasoning: The announcement provides a progress update on hole BS-4 rather than new assay results. While it mentions visual occurrences of copper, no numeric grades or intercepts are reported for the current hole.

- Positive factor: presence of native copper and chalcocite clasts

- Negative factor: drilling challenges and progress delays

- Negative factor: hole wedging through casing

Facts used in scoring: 1

## Classification and evidence

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: BS-4 is described as a step-out test of the chalcocite blanket drilled in BS-3.

Evidence · text

> Once the BS-4 step-out test of the chalcocite blanket drilled in BS-3 is completed

**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 mention specific assay protocols, lab certification, or QA/QC methods for the current drilling progress.

## 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.
