## Minestarters Atlas summary

Hercules Metals Corp. has reported step-out drill results from hole HER-26-01, extending the Southern Flats copper porphyry discovery at the Hercules Project in Idaho. The hole intersected 287 metres of 0.58% CuEq, including a high-grade 66-metre interval of 0.80% CuEq.

Reasoning: Significant step-out drill results extending a known porphyry discovery with high-grade intercepts.

- Positive factor: Step-out drilling extended mineralization

- Positive factor: High-grade sub-interval reported

- Positive factor: Discovery of second porphyry centre in district

Facts used in scoring: 8

## Classification and evidence

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: Hole HER-26-01 is a 200-metre step-out that extended mineralization west of the previous discovery hole.

Evidence · text

> 200-metre step-out drill hole HER-26-01 has extended mineralization west of the Southern Flats discovery hole HER-25-25

**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 disclose specific QA/QC protocols, lab certification, or QP sign-off for these assays.

Evidence · text

> HER-26-01 encountered transitional phyllic to outer potassic alteration

## 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.
