Hole YAR-45 intersected nearly 400m of continuous mineralisation from surface, including significant gold-equivalent intervals. Reasoning: The hole YAR-45 returned a very wide \(nearly 400m\) continuous gold-copper mineralised intercept starting from surface, which validates the geological model for this porphyry system. - Positive factor: significant intercept width - Positive factor: mineralisation from surface - Positive factor: confirms porphyry-style structure - Positive factor: open along strike and depth Facts used in scoring: 7 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: The results confirm the presence and structure of porphyry-style mineralisation within the project's core, validating the 3D model. Evidence · text > confirming the presence and structure of porphyry-style mineralisation within the project’s core P-1 host unit ## Extracted facts Stored fact records: 7.

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.
