The company is currently optimizing beneficiation to reduce high sulphuric acid consumption and is considering pausing the PEA update until these optimizations are complete. Reasoning: Metallurgical results show high recovery potential for titanium and rare earths, though high acid consumption remains a technical hurdle and the PEA is being paused for optimization. - Positive factor: high TREO extraction - Positive factor: high TiO2 recovery in fine particle flowsheet - Positive factor: encouraging beneficiation results - Negative factor: high sulphuric acid consumption - Negative factor: PEA potentially on hold Facts used in scoring: 7 ## Classification and evidence **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: Testwork involves fine particle flowsheet and sulphuric acid leaching. Evidence · text > Fine particle flow sheet \(< 20 micron\) using sulphuric acid **Refractory Ore** Polarity: negative Definition: Ore requires oxidation/pressure treatment before recovery — a processing and recovery risk. Why it applies: High sulphuric acid consumption \(700-1320 kg/t\) indicates complex mineralogy requiring intensive leaching. Evidence · text > Preliminary sulphuric acid consumption ranged from 700kg/t to 1,320kg/t ## Extracted facts Stored fact records: 7.
