Intercepts include 74m at 1.21% Cu and 6m at 3.01% Cu, extending the mineralized area and demonstrating continuity. Reasoning: Strong high-grade copper and silver step-out results that extend the known mineralized footprint at Pampa Medina. - Positive factor: high-grade copper intersections - Positive factor: step-out drilling success - Positive factor: extension of mineralized area - Positive factor: consistent silver mineralization Facts used in scoring: 4 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Hole SWRD-02 drilled approximately 600 metres west of previous drilling.

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.
