Preliminary metallurgical tests indicate that copper can be recovered using conventional flotation, potentially utilizing existing ilmenite infrastructure. Reasoning: Largo is demonstrating potential for significant byproduct revenue from copper and PGMs using existing infrastructure, which provides a strategic hedge against low vanadium prices. - Positive factor: Positive preliminary flotation results for copper - Positive factor: Potential to utilize existing ilmenite flotation infrastructure - Positive factor: High commodity prices for copper and PGMs - Positive factor: QA/QC protocols and accredited labs disclosed - Negative factor: Results are preliminary and internal - Negative factor: PGM assays are still pending 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: The company is evaluating using existing ilmenite flotation infrastructure for copper recovery. Evidence · text > Largo is evaluating using part of its existing ilmenite flotation infrastructure to reduce capital costs **QA/QC Disclosed** Polarity: positive Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\). Why it applies: The release explicitly mentions ISO/IEC 17025-accredited laboratories and specific QA/QC methods like standards and blanks. Evidence · text > All sample results during the period have been monitored through a QA/QC program that includes the insertion of certified standards, blanks, and pulp and reject duplicate samples. **Single Domain Only** Polarity: negative Definition: Testing limited to one composite or domain — representativeness not established.
