The results confirmed significant gold \(95.2 g/t\) and silver \(387.6 g/t\) credits and exceptionally low impurity levels, supporting the project's DFS and upcoming off-take discussions. Reasoning: Laboratory-scale smelting tests successfully produced high-purity \(98.9%\) blister copper with significant gold and silver credits, confirming the marketability of Cabaçal concentrates. - Positive factor: high purity blister copper - Positive factor: significant precious metal credits - Positive factor: low impurity levels - Positive factor: demonstrated smelting efficiency Facts used in scoring: 3 ## Classification and evidence **Free Milling** Polarity: positive Definition: Simple, clean ore amenable to standard processing without oxidation. Why it applies: The release describes high recoveries and efficient conversion of copper sulphides into high-quality blister copper. Evidence · text > demonstrate that Cabaçal's copper concentrates convert efficiently into high-quality copper blister **QP/CP Signed** Polarity: positive Story-specific tag Definition: Qualified Person \(QP\) or Competent Person \(CP\) named and signed off — a member of a recognized professional association \(e.g., AusIMM, SME, AIG, P.Geo\) with relevant experience. Why it applies: Dr. Norm Lotter, a Qualified Person, has reviewed and approved the technical information. Evidence · text > Dr. Norm Lotter... a Qualified Person as defined by National Instrument 43-101, has reviewed, verified and approved the technical information ## Extracted facts Stored fact records: 3.

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.
