The review also highlights molybdenum as a potential second payable product stream and confirms continued strong copper recovery potential. Reasoning: The review identifies a major potential step-change in gold recovery through process optimization, which significantly enhances the project's economic profile. - Positive factor: Significant potential increase in gold recovery \(from ~40% to ~73%\) - Positive factor: Identification of molybdenum as a separate potential revenue stream - Positive factor: Maintains strong copper recovery profiles - Positive factor: Use of flash flotation simulations to identify optimization pathways - Negative factor: Results are based on simulations and require Phase 2 confirmatory testing - Negative factor: Historical data is being re-evaluated, not new physical testwork on current material Facts used in scoring: 9 ## Classification and evidence **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: The review focuses on flotation optimization and cleaner-stage losses. Evidence · text > through a modified flotation approach **Bench Scale Only** Polarity: negative Definition: Only preliminary bench tests completed — no locked-cycle or pilot work. Why it applies: The review is a Phase 1 review based on simulations and historical bench-scale flotation tests. Evidence · text > The Phase 1 review does not constitute an updated... feasibility study ## Extracted facts Stored fact records: 9.
