The 2025 diamond drill program successfully identified continuity along a southwest-trending corridor, with mineralization remaining open at depth and along strike. Reasoning: Drill results confirm the extension of porphyry-style mineralization beyond historical intercepts, although grades remain in the low-to-moderate range for a porphyry system. - Positive factor: mineralization extension - Positive factor: continuity confirmed - Positive factor: open at depth and strike - Negative factor: low grades Facts used in scoring: 12 ## 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 mentions standards and blanks were inserted and results were verified by a QP. Evidence · text > Standards and blanks were inserted by the company **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Results confirm mineralization extending beyond the original 2007 discovery intercept. Evidence · text > extending beyond the original 2007 discovery intercept ## Extracted facts Stored fact records: 12.

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.
