Additionally, the company announced that its Cloncurry copper-equivalent resource has grown by 62% to 204,000t CuEq. Reasoning: The document reports successful flotation test results supporting processing assumptions and a significant increase in copper-equivalent resource tonnage. - Positive factor: Strong average copper recovery of 89% in flotation tests - Positive factor: Significant contained copper-equivalent resource growth of 62% - Positive factor: Successful bench-scale testing on multiple grade composites - Positive factor: PFS remains on track for late 2026 completion - Negative factor: Metallurgical results are bench-scale and require further validation at larger scales Facts used in scoring: 5 ## Classification and evidence **High Recovery** Polarity: positive Definition: Recovery at or above the exceptional band for the commodity and processing route. Why it applies: Average copper recovery of 89% is strong for flotation. Evidence · text > average copper recovery of 89% **Tonnage Growth** Polarity: positive Definition: Significant tonnage increase \(≥15%\) vs prior estimate with grade maintained or improved. Why it applies: Copper-equivalent resource increased by 62% vs prior. Evidence · text > boosted contained copper-equivalent resources at Cloncurry by 62% **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: the document describes a flotation route \("flotation"\) **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: 5.
