The company also reported Phase 1 drill results, including the discovery of Carlin-like sediment-hosted gold indicators at the Luis Hill target. Reasoning: The release reports high-grade surface sampling and significant new geological findings \(SHGD style\) that expand the project's potential beyond the initial CRD target. - Positive factor: High-grade chip-channel sampling \(20 g/t Au\) - Positive factor: Discovery of new sediment-hosted gold \(SHGD\) style at Luis Hill - Positive factor: Successful identification of CRD-style mineralization across multiple targets - Positive factor: Presence of multiple metals \(Au, Ag, Zn, Pb\) consistent with regional targets - Negative factor: Channel sampling does not represent true width - Negative factor: Drilling lost in underground workings at Union Mine Facts used in scoring: 6 ## Classification and evidence **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: 30m chip-channel sampling at 20 g/t Au is exceptionally high grade for the region. Evidence · text > 30m grading 20 g/t Au and 226 g/t Ag **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 high-grade channel sample is noted as not representing true width. Evidence · text > Channel sampling along the mine adit entrance access wall and does not represent true width **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 lab names, standards, blanks, and duplicates. Evidence · text > Standards were inserted every 20 samples and blanks every 100 samples. The laboratory also duplicated every 20 samples **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Discovery of SHGD-style mineralization at Luis Hill represents a new finding for this part of Sonora. Evidence · text > This represents a new finding for this part of Sonora and is significant for both the property and the region ## Extracted facts Stored fact records: 6.

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.
