The results demonstrate that a single conventional flowsheet can achieve up to 90% gold and 91% copper recovery across both stockwork and tonalite mineralization types. Reasoning: Strong first-pass metallurgical results \(up to 90% Au\) across two mineralization styles provide significant de-risking ahead of a resource update. - Positive factor: High gold and copper recoveries achieved via a single flowsheet - Positive factor: Gold is free-milling, reducing processing complexity - Positive factor: Improved recoveries compared to historical testwork - Positive factor: Strong silver recovery demonstrated for the first time Facts used in scoring: 8 ## Classification and evidence **Free Milling** Polarity: positive Definition: Simple, clean ore amenable to standard processing without oxidation. Why it applies: Gold proved consistently free milling in the tested material, without requiring sulphide pre-oxidation. Evidence · text > Gold proved consistently free milling in the tested material **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: The proposed route involves grinding, flotation, and leaching. Evidence · text > The proposed route starts with grinding and copper flotation **Multi-Domain Tested** Polarity: positive Definition: Variability across ore domains \(oxide, transition, fresh\) has been addressed. Why it applies: 2 distinct composites were tested ## Extracted facts Stored fact records: 8.
