Agitation leach achieved up to 99% gold recovery, while heap leach using HPGR crushing achieved 84% gold recovery. Reasoning: Strong metallurgical results from bulk sampling demonstrating high recovery potential for both agitation and heap leach routes, supported by professional oversight. - Positive factor: High gold recovery \(up to 99%\) in agitation leach - Positive factor: Effective heap leach recovery \(84%\) using HPGR crushing - Positive factor: Low cyanide and lime consumption - Positive factor: QA/QC disclosed with QP sign-off Facts used in scoring: 4 ## Classification and evidence **High Recovery** Polarity: positive Definition: Recovery at or above the exceptional band for the commodity and processing route. Why it applies: Gold recovery of 91-99% in agitation leach is in the exceptional band. Evidence · text > Gold recovery of 91-99% was achieved by agitation leach cyanidation **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: Agitation leach is a mill-based processing route. Evidence · text > Gold recovery of 91-99% was achieved by agitation leach cyanidation **Heap Leach Route** Polarity: neutral Definition: Processing via heap leach — lower CAPEX and OPEX, lower recovery expected. Why it applies: Results include heap leach cyanidation testing. Evidence · text > Gold recovery of 84% was achieved by heap leach **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 names a Qualified Person \(Gregory Hahn\) and an independent commercial lab \(KCA/Florin\). Evidence · text > Qualified Person Gregory Hahn... is a Qualified Person under National Instrument 43-101 **Single Domain Only** Polarity: negative Definition: Testing limited to one composite or domain — representativeness not established. Why it applies: only one composite was tested ## Extracted facts Stored fact records: 4.

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.
