## Minestarters Atlas summary

Corvus Gold announced further drill results from its North Bullfrog exploration program, extending the YellowJacket structural zone by an additional 250 metres north of the existing resource. The program also highlighted the re-emerging Liberator structural zone as a new target with significant gold and silver mineralization, including a broad intercept of 153.92 metres at 0.54 g/t gold. These results are expected to rapidly expand the potential for new resources within the immediate proximity of the current pit design.

Reasoning: Corvus Gold reported new drill results that significantly extend the YellowJacket deposit and highlight a new parallel structural zone \(Liberator\), indicating substantial resource expansion potential. While many grades are low, the broad widths of mineralization are positive for bulk tonnage, and robust QA/QC procedures support the data's reliability, despite the lack of true width disclosure.

- Positive factor: Significant widths of mineralization

- Positive factor: Extension of known deposit

- Positive factor: Identification of new target zone

- Positive factor: Good QA/QC disclosure

- Negative factor: True width not disclosed

- Negative factor: Many intercepts are low grade

Low confidence — this extraction should be reviewed alongside the original source.

Facts used in scoring: 58

## Classification and evidence

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The release states that drilling has extended the YellowJacket Zone an additional 250 metres to the north of the existing resource.

Evidence · text

> Drilling has now extended the YellowJacket Zone an additional 250 metres to the north of the existing resource

**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: The document details QA/QC procedures including insertion of standards and blanks, analysis by ALS Chemex \(ISO 9001:2000 and ISO 17025:1999 compliant\), and review by Qualified Persons.

Evidence · text

> Quality control is monitored by the insertion of blind certified standard reference materials and blanks into each sample shipment. All resource sample shipments are sealed and shipped to ALS Chemex in Reno, Nevada , for preparation and then on to ALS Chemex in Reno, Nevada , or Vancouver, B.C. , for assaying. ALS Chemex's quality system complies with the requirements for the International Standards ISO 9001:2000 and ISO 17025:1999.

**Compositing Transparent**

Polarity: positive

Definition: Cut-off grade and internal dilution rules are clearly stated for reported intervals.

Why it applies: The footnote to the drill results table explicitly states the cut-off grade and internal dilution rules used for calculating mineralized thickness.

Evidence · text

> \* Mineralized thickness calculated @ 0.10 g/t Au cutoff with internal vein/stockwork intervals calculated @ 0.5 g/t Au cutoff

**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 drill results table explicitly states that 'Reported drill intercepts are not true widths' and that there is 'insufficient data with respect to the shape of the mineralization to calculate its true orientation in space.'

Evidence · text

> Reported drill intercepts are not true widths. At this time, there is insufficient data with respect to the shape of the mineralization to calculate its true orientation in space.

## 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.
