The results, based on 7 additional diamond drill holes, reveal two parallel mineralized horizons and include a 20.0 meter composite intercept. Reasoning: The discovery has expanded significantly in strike length, demonstrating continuity across a large structural corridor, though technical uncertainty remains due to the reliance on radiometrics rather than assays. - Positive factor: significant strike length extension from 300m to 1.45km - Positive factor: two parallel mineralized horizons identified - Positive factor: system remains open in all directions - Positive factor: widest intercept of 20m composite mineralization - Negative factor: results are preliminary gamma-probe readings pending laboratory assays - Negative factor: true thickness not yet determined - Negative factor: step-out holes are widely spaced Facts used in scoring: 5 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: The drilling has extended the traced mineralization continuity from 300 meters to 1.45 kilometers. Evidence · text > extending traced mineralization continuity from 300 meters to 1.45 kilometers **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 company has not yet determined true thickness for any of the reported intercepts; all figures are core-length measurements. Evidence · text > the company has not yet determined true thickness for any of the reported intercepts, since all figures to date are reported as core-length or core width measurements **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 mentions an ISO/IEC 17025-accredited laboratory and the use of gamma probe readings. Evidence · text > Saskatchewan Research Council Geoanalytical Laboratories in Saskatoon, an ISO/IEC 17025:2005-accredited facility ## Extracted facts Stored fact records: 5.

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.
