Sulphide flotation returned 89% gold recovery, while oxide agitated cyanide leaching returned 82% gold recovery. Reasoning: The announcement reports successful metallurgical recoveries \(>80%\) for both sulphide and oxide material at the Palta Dorada property, supporting future processing plans. - Positive factor: Recoveries exceeding 80% for both oxide and sulphide material - Positive factor: High head grades reported for both domains - Positive factor: QP sign-off provided - Negative factor: Historical sample mentioned as non-representative - Negative factor: Development delays due to infrastructure damage Facts used in scoring: 4 ## Classification and evidence **QA/QC Disclosed** Polarity: positive Story-specific tag Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\). Why it applies: Release mentions assaying by Procesmin Ingenieros SRL using fire assay and QP sign-off by Jeffrey Reeder, P. Geo. Evidence · text > Qualified Person Jeffrey Reeder, P. Geo., is the Qualified Person, as defined in National Instrument 43-101 **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: Sulphide material will be treated at the Aguila Norte plant using flotation.

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.
