The drilling extended high-grade mineralization to over 1,100m depth and 600m strike, indicating the South Pit resource is set to grow. The company plans further step-out and infill drilling to define the limits of the high-grade zone. Reasoning: Drill results from CB-229 and CB-230 demonstrate significant extensions of high-grade copper-gold-silver-molybdenum porphyry mineralization at the Cotabambas Project, with continuity from surface to over 1,100m depth and along 600m of strike, suggesting substantial resource growth potential. - Positive factor: High-grade intercepts - Positive factor: Significant intercept lengths - Positive factor: Step-Out Extension - Positive factor: Continuity at depth - Positive factor: Potential for skarn mineralization - Positive factor: QA/QC Disclosed - Positive factor: QP/CP Signed - Negative factor: Apparent Width Only - Negative factor: Cut-off Undisclosed Facts used in scoring: 43 ## Classification and evidence No classification tags are available. ## Extracted facts Stored fact records: 43.

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.
