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

Facts used in scoring: 78

## Classification and evidence

**Bonanza Intercept**

Polarity: positive

Definition: Exceptionally high-grade zone, well above the deposit-type norm.

Why it applies: Hole NB-15-282 returned 4.97 g/t gold over 3.05 meters, which is an exceptional grade for gold.

Evidence · table

> 4.97

Context: 3.05

**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 explicitly states '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.'

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.

**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 certified lab \(ALS Chemex\), QP sign-off, and methods like standards, blanks, and duplicates.

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. Analytical accuracy and precision are monitored by the analysis of reagent blanks, reference material and replicate samples. Finally, representative blind duplicate samples are forwarded to ALS Chemex and an ISO compliant third party laboratory for additional quality control.

**Cut-off Undisclosed**

Polarity: negative

Definition: High-grade interval reported without stating the cut-off grade used for compositing.

Why it applies: The document states 'Mineralized thickness calculated @ 0.10 g/t Au cutoff with internal vein/stockwork intervals calculated @ 1.0 g/t Au cutoff' for drill results, but does not explicitly state internal dilution rules for the 0.10 g/t Au cutoff.

Evidence · text

> Mineralized thickness calculated @ 0.10 g/t Au cutoff with internal vein/stockwork intervals calculated @ 1.0 g/t Au cutoff

**Stale Data Re-release**

Polarity: negative

Definition: Historical results re-announced with no new assays or reinterpretation — low genuine novelty.

Why it applies: The section 'Previously releases NW Sierra Blanca/Rhyolite Zone Results' indicates that these drill results are historical and not new information.

Evidence · text

> Previously releases NW Sierra Blanca/Rhyolite Zone Results

**NI 43-101 Compliant**

Polarity: positive

Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard.

Why it applies: The resource estimates are stated to be prepared in accordance with NI 43-101.

Evidence · text

> all resource estimates contained in or incorporated by reference in this press release have been prepared in accordance with NI 43-101

**QP/CP Signed**

Polarity: positive

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. Mr. Pontius is not independent of Corvus, as he is the CEO & President and holds common shares and incentive stock options. 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.

**Cut-off Disclosed**

Polarity: positive

Definition: Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.

Why it applies: The cut-off grades for both mill processing \(0.52 g/t gold\) and heap leach processing \(0.15 g/t\) are clearly stated for the resource estimates.

Evidence · text

> a breakeven cut-off grade of 0.52 g/t gold

**Inferred Resource**

Polarity: negative

Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone.

Why it applies: The document reports significant Inferred Mineral Resources for both mill and heap leach processing.

Evidence · text

> an inferred resource of 1.48 Mt at an average grade of 0.83 g/t gold and 4.26 g/t silver

**Stale Estimate**

Polarity: negative

Definition: Effective date is >2 years old — data currency concern, may not reflect current geological understanding.

Why it applies: The effective date of the resource estimate is June 16, 2015, which is over two years old relative to the current date.

## 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.
