## Minestarters Atlas summary

Hercules Metals has reported significant drill results from the Leviathan Porphyry system in Idaho, including an 801.6 m intercept of 0.40% CuEq. The company also identified a strong new chargeability anomaly at the Hook target and is continuing exploration at the Pegasus target.

Reasoning: The announcement reports very wide, high-grade copper-equivalent intercepts at a porphyry system, extending known mineralization and identifying new targets via IP.

- Positive factor: significant intercept width

- Positive factor: high-grade near-surface intercepts

- Positive factor: extension of known mineralization

- Positive factor: strong geophysical anomalies

- Negative factor: true width not disclosed

Facts used in scoring: 44

## Classification and evidence

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: HER-25-21 extends Leviathan's Footwall Zone to the southwest.

Evidence · text

> extends Leviathan's Footwall Zone to the southwest

**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: Release includes detailed QA/QC protocols, lab certification \(ISO 17025\), and QP sign-off.

Evidence · text

> an ISO 17025 and ISO 9001 certified laboratory

**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 states that insufficient data is available to state the true thickness of the mineralized intervals.

Evidence · text

> insufficient data are available at this time to state the true thickness

Reasoning: Expanded from assay table. 0.039 g/t gold is below against the porphyry deposit band \[1, 0.5, 0.3, 0.15\] g/t. Grade×width 0.7 g/t·m is below.

- Negative factor: 0.039 g/t gold is below the weak threshold \(0.15 g/t\) on the porphyry deposit band.

- Negative factor: Scored from rubric bands during table expansion, not from document context.

## 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.
