## Minestarters Atlas summary

Corvus Gold has announced a new high-grade gold-silver intercept of 10.7m at 3.47 g/t Au and 3.6 g/t Ag from its Rhyolite Zone at the North Bullfrog Project in Nevada. This discovery represents a new center of mineralization expanding the potential of the YellowJacket deposit system.

Reasoning: The announcement reports a significant new high-grade gold-silver intercept \(10.7m @ 3.47 g/t Au\) that expands a new vein zone discovery east of an existing deposit.

- Positive factor: new high-grade intercept

- Positive factor: expansion of known mineralization

- Positive factor: district-scale potential

- Negative factor: intercepts are not true widths

Facts used in scoring: 12

## Classification and evidence

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The results represent a new center of mineralization east of the existing YellowJacket deposit.

Evidence · text

> represents a new center of gold-silver mineralization immediately east of the YellowJacket deposit

**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 release details QA/QC procedures including blind certified standards, blanks, and duplicate samples sent to ALS Chemex.

Evidence · text

> Quality control is monitored by the insertion of blind certified standard reference materials and blanks

**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 table explicitly states that reported drill intercepts are not true widths.

Evidence · text

> Reported drill intercepts are not true widths

## 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.
