The porphyry stock, intersected in hole SC-26-01, extends over 400m and is located 1.5km from the MEPS Discovery zone, suggesting a giant porphyry copper system. Reasoning: The discovery of a large, 400m+ thick porphyry stock 1.5km from a known discovery zone is a major exploration milestone, though the lack of actual assays for the new hole limits immediate grade verification. - Positive factor: Discovery of a large porphyry stock complex - Positive factor: Significant vertical extent \(>400m\) - Positive factor: Proximity to known MEPS discovery - Positive factor: Presence of potassic alteration and bornite - Negative factor: Assays are not yet available for the new hole \(visual logging only\) - Negative factor: True width not yet determined 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 hole was designed as a large step-out to the MEPS Discovery. Evidence · text > as a large step-out to the MEPS Discovery **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 provides detailed QA/QC protocols, including lab accreditation and specific method counts. Evidence · text > Analytical services were provided by Actlabs, which is an independent, CALA- and SCC-accredited analytical services firm registered to ISO 17025 and ISO 9001 standard. **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 document explicitly states that interval widths may not represent true widths which are not yet known. Evidence · text > Intervals may not represent true widths which are not yet known ## 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.
