## Minestarters Atlas summary

PolarX has intersected significant massive to semi-massive sulphide zones at its Caribou Dome project in Alaska, including a 57.5m intercept in hole CD26-009. These results, which are currently visual and awaiting assays, were found outside the existing copper resource and suggest the presence of new mineralisation styles and potential feeder zones.

Reasoning: Significant visual massive sulphide intercepts \(57.5m\) found outside the existing resource, suggesting potential for major resource expansion and new discovery styles.

- Positive factor: discovery of new mineralisation style

- Positive factor: massive sulphide intercepts outside existing resource

- Positive factor: potential feeder zone identification

- Positive factor: fully funded exploration campaign

- Negative factor: assays are still pending

Facts used in scoring: 2

## Classification and evidence

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: Mineralisation intersected outside the existing Caribou Dome copper resource.

Evidence · text

> uncovers massive sulphide zone outside Caribou Dome copper resource

**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 mentions assays are pending but does not disclose specific QA/QC protocols or lab certification for the current campaign.

Evidence · text

> Assays from the two holes are pending.

## 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.
