Surface grab samples returned high-grade assays including up to 8.1% Cu and 36.8 g/t Au, with magnetic data suggesting a potential strike length of ~1 km. Reasoning: The identification of a new copper-gold porphyry target with high-grade surface grab samples \(8.1% Cu and 36.8 g/t Au\) represents a significant exploration discovery at the Ruby Creek Project. - Positive factor: High-grade copper intercepts \(8.1% Cu\) - Positive factor: High-grade gold intercepts \(36.8 g/t Au\) - Positive factor: Discovery of a new porphyry target - Positive factor: Multi-metal potential \(Cu, Au, Ag, Mo\) - Negative factor: Results are from grab samples \(surface only\) - Negative factor: No drill intercepts reported yet Facts used in scoring: 4 ## 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 specific QA/QC protocols including lab names \(Bureau Veritas\), digestion methods, and fire assay procedures. Evidence · text > All results have passed the QA/QC screening by the lab. **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: Silver grades of 16,030 g/t Ag are exceptionally high. Evidence · text > silver samples up to 16,030 g/t Ag ## Extracted facts Stored fact records: 4.

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.
