The drilling extends the known high-grade mineralization from surface to over 1,100 meters depth and along 600 meters of strike, with intercepts including 808.15 meters at 0.31% CuEq in CB-230. The program also identified Endoskarn mineralization for the first time, suggesting potential for massive skarn deposits, and confirms the project's potential for significant resource growth. Reasoning: New drill results from CB-229 and CB-230 confirm significant extensions of copper-gold-molybdenum porphyry mineralization at the Cotabambas project, demonstrating continuity over large vertical and strike extents, and identifying new skarn potential, despite individual metal grades being moderate. The long intercepts and extension of mineralization are highly material. - Positive factor: Long intercepts - Positive factor: Step-Out Extension - Positive factor: Vertical continuity - Positive factor: Widening at depth - Positive factor: New skarn mineralization identified - Positive factor: QA/QC Disclosed - Negative factor: Apparent Width Only - Negative factor: Individual metal grades generally below project average Facts used in scoring: 48 ## Classification and evidence No classification tags are available. ## Extracted facts Stored fact records: 48.

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.
