Key results include 3.05 metres at 2.05 g/t gold and 178 g/t silver at Savage, with some holes ending in mineralization, suggesting expansion potential. The company also restated its existing mineral resource estimates from June 2015 for both mill and heap leach processing, which are compliant with NI 43-101 standards. Reasoning: Corvus Gold announced positive exploration drill results from new target areas at its North Bullfrog Project, identifying new mineralization and high-grade intercepts, with strong QA/QC. However, the resource update is historical, and true widths are not provided for drill intercepts. - Positive factor: New zones of gold-silver mineralization identified at Savage, Rhyolite, and North YellowJacket targets - Positive factor: High-grade gold and silver intercepts, including 3.05m @ 2.05 g/t Au and 178 g/t Ag at Savage - Positive factor: Holes ending in mineralization suggest potential for further extension - Positive factor: Evidence of a deeper, higher-temperature mineral system at Savage, indicating porphyry potential - Positive factor: Comprehensive QA/QC procedures disclosed with certified lab and QP sign-off - Negative factor: Intercepts are reported as apparent width only, true width is not known - Negative factor: Presence of deleterious elements \(antimony, tellurium, arsenic\) noted in some intercepts - Negative factor: Resource update is a restatement of a prior estimate from June 2015, not new information Low confidence — this extraction should be reviewed alongside the original source. Facts used in scoring: 83 ## Classification and evidence **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 blanks, standards, duplicates, and use of a certified lab. 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. **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, both qualified persons, have 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. **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 that reported drill intercepts are not true widths. 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. **Deleterious Elements Present** Polarity: negative Definition: A source-stated penalty, refractory or recovery concern in the fact's scope. Element detection alone, including measured elements explicitly below penalty thresholds, does not trigger this tag. Respect negation and retain a separately stated concern even when another risk is explicitly absent. Why it applies: Intercepts at the Savage target had high antimony, tellurium, and arsenic numbers. Evidence · text > In addition to copper grades up to 0.2%, the intercepts had high antimony, tellurium and arsenic numbers, suggesting a possible porphyry/intrusive association. **Compositing Transparent** Polarity: positive Definition: Cut-off grade and internal dilution rules are clearly stated for reported intervals. Why it applies: The cut-off grades for mineralized thickness and internal vein/stockwork intervals are clearly stated. Evidence · text > Mineralized thickness calculated @ 0.10 g/t Au cutoff with internal vein/stockwork intervals calculated @ 1.0 g/t Au cutoff **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Hole NB-15-276 is described as a ~30 metres step out drill hole to the northeast. Evidence · text > NB-15-276 was a ~30 metres step out drill hole to the northeast. **Infill Drilling** Polarity: neutral Definition: Confirmatory drilling to raise resource confidence, not new discovery. Why it applies: Drilling at the Savage target was immediately adjacent to the southern portion of the Sierra Blanca deposit, indicating resource expansion or infill. Evidence · text > Three holes were drilled in the main Savage target immediately adjacent to the southern portion of the Sierra Blanca deposit. **Stale Data Re-release** Polarity: negative Definition: Historical results re-announced with no new assays or reinterpretation — low genuine novelty. Why it applies: The mineral resource estimates are a restatement of figures from a technical report dated June 16, 2015. Evidence · text > see "Technical Report and Preliminary Economic Assessment for Combined Mill and Heap Leach Processing at the North Bullfrog Project, Bullfrog Mining District, NYE County, Nevada " dated June 16, 2015 **Cut-off Disclosed** Polarity: positive Definition: Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison. Why it applies: Cut-off grades for both mill and heap leach processing resources are explicitly stated. Evidence · text > a breakeven cut-off grade of 0.52 g/t gold. In addition, the project contains a measured mineral resource of 0.3 Mt at an average grade of 0.25 g/t gold and 2.76 g/t silver, containing 2.4k ounces of gold and 26.6k ounces of silver and an inferred mineral resource of 176.3 Mt at an average grade of 0.19 g/t gold and 0.67 g/t silver, containing 1,077.4k ounces of gold and 3,799.2k ounces of silver for oxide, heap leach processing. The mineral resource for heap leach processing was defined by Whittle TM optimization using all cost and recovery data and a breakeven cut-off grade of 0.15 g/t. **NI 43-101 Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard. Why it applies: All resource estimates are stated to be prepared in accordance with NI 43-101. Evidence · text > Unless otherwise indicated, all resource estimates contained in or incorporated by reference in this press release have been prepared in accordance with NI 43-101 **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 portions of the resource in the Inferred category 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, containing 39.5k ounces of gold and 202.7k ounces of silver for oxide mill processing. ## Extracted facts Stored fact records: 83.

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.
