## Minestarters Atlas summary

Corvus Gold announced initial drill results from its 2016 North Bullfrog exploration program, highlighting a new gold-silver discovery at the Swale target and an extension of mineralization at the NW Sierra Blanca target. Key intercepts include 18.3m of 1.76 g/t gold and 2.4 g/t silver at Swale, and 22.9m of 1.69 g/t gold and 2.64 g/t silver at NW Sierra Blanca. These results demonstrate continuity of mineralization and potential for resource growth, with the Swale discovery characterized by extensive quartz stockwork mineralization associated with a rhyolite intrusive.

Reasoning: Corvus Gold announced significant new gold-silver discoveries and extensions at its North Bullfrog Project, with several wide intercepts showing gold grades above the project average, indicating strong potential for resource expansion. The new Swale discovery and the extension at NW Sierra Blanca are highly novel, though true widths were not reported.

Facts used in scoring: 74

## Classification and evidence

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: Drilling at the NW Sierra Blanca target has extended gold mineralization to the northeast toward the current north end of the YellowJacket deposit.

Evidence · text

> Drilling at the NW Sierra Blanca target has extended gold mineralization to the northeast toward the current north end 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 insertion of standards and blanks, and mentions ALS Chemex as the certified laboratory.

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: Mineralized thickness is calculated at a 0.10 g/t Au cutoff with internal vein/stockwork intervals at a 0.5 g/t Au cutoff.

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 intercepts are explicitly stated as not true widths, with insufficient data to calculate true orientation.

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.

**QP/CP Signed**

Polarity: positive

Story-specific tag

Definition: Qualified Person \(QP\) or Competent Person \(CP\) named and signed off — a member of a recognized professional association \(e.g., AusIMM, SME, AIG, P.Geo\) with relevant experience.

Why it applies: Jeffrey A. Pontius and Carl E. Brechtel are named as Qualified Persons who supervised and approved the disclosure.

Evidence · text

> Jeffrey A. Pontius \(CPG 11044\), a qualified person as defined by National Instrument 43-101, has supervised the preparation of the scientific and technical information that forms the basis for this news release and has approved the disclosure herein. ... Carl E. Brechtel , \(Nevada PE 008744 and Registered Member 353000 of SME\), a qualified person as defined by National Instrument 43-101, has coordinated execution of the work outlined in this news release and has approved the disclosure herein.

## 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.
