The tests demonstrated successful production of a vanadium-magnetite concentrate and showed that vanadium can be selectively extracted via oxidative roasting and sulfuric acid leaching, reaching up to 65% recovery at 1050°C. Reasoning: Interim results show technical feasibility of producing a vanadium-rich concentrate and selective extraction, though results are from non-optimized scoping-level tests. - Positive factor: selective vanadium extraction demonstrated - Positive factor: successful production of vanadium-magnetite concentrate - Positive factor: positive correlation between roasting temperature and recovery - Negative factor: preliminary/non-optimized laboratory conditions - Negative factor: relatively low vanadium recovery \(65%\) at high temperature Facts used in scoring: 3 ## Classification and evidence **Bench Scale Only** Polarity: negative Definition: Only preliminary bench tests completed — no locked-cycle or pilot work. Why it applies: The results are described as preliminary, non-optimized, and scoping-level laboratory tests. Evidence · text > The metallurgical test work reported herein is preliminary in nature and was conducted under non-optimized laboratory conditions. **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: The process involves grinding and magnetic separation. Evidence · text > The Lac Doré material demonstrated a consistent response to conventional grinding and magnetic separation techniques **QP/CP Signed** Polarity: positive Story-specific tag Definition: Qualified Person \(QP\) or Competent Person \(CP\) named and signed off — a member of a recognized professional association \(e.g., AusIMM, SME, AIG, P.Geo\) with relevant experience. Why it applies: André Gauthier, P.Geo., a Qualified Person, reviewed and approved the technical information.

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.
