The system consists of gold-bearing epithermal quartz veins, with trenching revealing high-grade gold and silver intercepts. Reasoning: Discovery of a new epithermal vein system with high-grade surface showings \(up to 24.66 g/t Au\) in an advanced exploration project. - Positive factor: New gold system discovery \(NW Vein System\) - Positive factor: High-grade channel samples in trenches - Positive factor: Epithermal quartz vein signatures - Positive factor: QA/QC protocols disclosed - Negative factor: Undrilled zone \(requires verification\) - Negative factor: True width of historical hole unknown Facts used in scoring: 7 ## 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: Release details specific QA/QC protocols including blanks, standards, and duplicates. Evidence · text > The Company carried out a very careful and systematic Quality Assurance/Quality Control program **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: 24.66 g/t Au is exceptionally high grade for an epithermal system. Evidence · text > 24.66 g/t Au ## Extracted facts Stored fact records: 7.
