## Minestarters Atlas summary

Onyx Gold has reported significant near-surface gold mineralization at the Argus North zone of the Munro-Croesus Project. Results include high-grade drill intercepts up to 5.0 g/t Au and wide channel samples, confirming a continuous mineralized system from surface to depth.

Reasoning: The release reports significant high-grade gold intercepts from both step-out drilling and surface channel sampling, confirming the potential of a near-surface discovery at Argus North.

- Positive factor: High-grade near-surface intercepts

- Positive factor: Wide mineralization continuity

- Positive factor: Step-out drilling confirms extension

- Positive factor: Strong QA/QC disclosure

- Negative factor: True width not explicitly stated for all intercepts \(estimated 70-90%\)

Facts used in scoring: 10

## Classification and evidence

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: Drilling results from step-out holes confirm mineralization extension.

Evidence · text

> step-out drilling up to 5.0 g/t Au over 8.6 m

**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 details specific lab methods \(photon assay, fire-assay\), standards, and blanks/duplicates.

Evidence · text

> The Company maintains a robust QA/QC program that includes the collection and analysis of duplicate samples and the insertion of blanks and standards

**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: Intersections are reported as drilled width with true width only estimated as 70-90%.

Evidence · text

> Intersections are reported as drilled width; true width is estimated to be 70-90% of drilled width.

## 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.
