Minestarters Atlas analysis

Summary

Corvus Gold has commenced its 2016 Phase I drill program at the North Bullfrog Project in Nevada, focusing on the NW Sierra Blanca and Lower Savage targets. The 5,000 metre RC program aims to expand high-grade zones and test new structural targets identified during 2015 exploration.

Reasoning: The company is initiating a targeted drill program to expand known high-grade zones and test new structural targets, supported by a significant existing resource base.

Positive factors

  • commencement of targeted Phase I drill program
  • expansion of high-grade NW Sierra Blanca target
  • testing of new Lower Savage target with high silver/copper potential
  • substantial existing NI 43-101 mineral resources

Facts used in scoring: 18

Classification and evidence

QA/QC Disclosedpositive

Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods (blanks, standards, duplicates).

Why it applies: The release mentions blind certified standard reference materials, 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”

NI 43-101 Compliantpositive

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

Why it applies: The resource estimates and technical information are prepared in accordance with NI 43-101 standards.

Evidence · text

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

Inferred Resourcenegative

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

Why it applies: The project contains significant inferred resource components in both mill and heap leach scenarios.

Evidence · text

“an inferred resource of 1.48 Mt at an average grade of 0.83 g/t gold”

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.
