Surface grab samples returned high-grade intercepts including up to 8.1% Cu and 36.8 g/t Au, with magnetic data suggesting a strike length of approximately 1 km. Reasoning: Discovery of a new copper-gold porphyry target with high-grade surface grab samples and supporting magnetic data. - Positive factor: High-grade copper intercepts up to 8.1% - Positive factor: High-grade gold intercepts up to 36.8 g/t - Positive factor: Discovery of a new porphyry target - Positive factor: QA/QC protocols and QP sign-off disclosed - Negative factor: Results are from grab samples \(surface/talus\), not drill intercepts - Negative factor: Scale and continuity are currently conceptual 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: Release details specific lab protocols, digestion methods, and verification by a QP. 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. Some facts used in scoring do not have a stored record. ## Drill Results (4) ### Fact 1 [Link to this fact](https://atlas-extractions.minestarters.com/news/stuhini-identifies-high-grade-copper-gold-porphyry-target-at-ruby-creek-project--7e41d74b-1e10-4d37-974c-9ebe5ba92be6#fact-drill-facts-0) Ruby Creek Project · copper #### Identity - Project: Ruby Creek Project - Commodity: copper - Region: canada\_bc - Reported Region: British Columbia - Ticker: STU #### Geometry - Grade: 8.1 - Grade Unit: % #### Classification - Sample Type: surface #### Location - Location: Ruffner - Loc.

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.
