The results, which include a high-grade copper-gold concentrate, outperform historical production data and support the development of a conventional flotation and leaching flowsheet. Reasoning: The metallurgical program achieved high recoveries \(90% Cu, 88% Au\) that exceed historical performance, supporting the project's PEA advancement. - Positive factor: Strong copper and gold recoveries - Positive factor: High-grade concentrate - Positive factor: Recoveries exceed historical production figures - Positive factor: Demonstrated high recovery in rougher flotation - Negative factor: Requires additional testing to optimize flowsheet Facts used in scoring: 6 ## Classification and evidence **High Recovery** Polarity: positive Definition: Recovery at or above the exceptional band for the commodity and processing route. Why it applies: Achieved 90.3% copper and 88% gold recovery. Evidence · text > Achieves 90% Copper Recovery and 88% Gold Recovery **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: Processing involves flotation and leaching. Evidence · text > Simplified conventional processing flowsheet consisting of primary grinding, copper flotation, concentrate cleaning and leaching of cleaner tailings. **Heap Leach Route** Polarity: neutral Definition: Processing via heap leach — lower CAPEX and OPEX, lower recovery expected. Why it applies: the document describes a heap\_leach route \("heap leach"\) **Gravity Route** Polarity: neutral Definition: Gravity separation forms a material part of the flowsheet. Why it applies: the document describes a gravity route \("gravity"\) **Multi-Domain Tested** Polarity: positive Definition: Variability across ore domains \(oxide, transition, fresh\) has been addressed. Why it applies: 3 distinct composites were tested ## Extracted facts Stored fact records: 6.
