Copper extraction rates reached up to 95% for high sulphidation samples, prompting the definition of a phase two column testing program. Reasoning: Positive extraction rates \(up to 95% Cu\) for various mineralization styles demonstrate technical potential for the AntaKori project using Nuton technology. - Positive factor: High copper extraction rates achieved in shaker flask tests - Positive factor: Amenability to proprietary sulphide leach technology confirmed - Positive factor: Phase two program \(column tests\) already defined - Negative factor: Small scale shaker flask tests may not predict larger scale performance - Negative factor: Technology is proprietary and relatively new Facts used in scoring: 3 ## Classification and evidence **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: The technology involves a sulphide leach process using shaker flasks and planned column tests. Evidence · text > phase one sulphide leach program **Bench Scale Only** Polarity: negative Definition: Only preliminary bench tests completed — no locked-cycle or pilot work. Why it applies: Results were achieved in shaker flasks, which are preliminary bench-scale tests. Evidence · text > This round of test work utilized relatively small samples and was completed in shaker flasks. ## Extracted facts Stored fact records: 3.

Sentiment reflects the extracted narrative and classification rules; it is an interpretation, not a reported measurement. Evidence quotes and context are provided where available. Missing data, low-confidence results, and review flags indicate limitations. Check the original publisher announcement before relying on an interpretation.
