The LCT produced a 5.5% Li2O concentrate with global recoveries of 77%-81% at laboratory scale and achieved a 39% reduction in reagent use. The company said further bulk float and pilot plant test work is planned for later in 2022. Reasoning: Completed locked cycle testwork on the Barroso Lithium Project shows encouraging lithium flotation performance and reagent optimization, supporting the upcoming DFS. The work is positive but remains laboratory scale and not yet pilot scale. - Positive factor: LCT completed successfully - Positive factor: concentrate grade of 5.5% Li2O - Positive factor: global recoveries in the range of 77%-81% at laboratory scale - Positive factor: 39% reduction in reagent use - Negative factor: results are based on lab scale - Negative factor: industry standard scale up factors should be applied - Negative factor: pilot plant testing is still planned Facts used in scoring: 7 ## Classification and evidence **High Recovery** Polarity: positive Definition: Recovery at or above the exceptional band for the commodity and processing route. Why it applies: The locked-cycle testing reported 77%-81% global recovery and 81.5% global recovery on the final cycles, which is strong for lithium flotation. Evidence · text > global recoveries in the range of 77%-81% **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: The release describes a spodumene flotation circuit with dense media separation, de-sliming and magnetic separation, which is a mill/concentrator route. Evidence · text > a continuous circuit found in a spodumene flotation plant **Bench Scale Only** Polarity: negative Definition: Only preliminary bench tests completed — no locked-cycle or pilot work. Why it applies: The work is explicitly described as laboratory scale and the company says pilot plant test work is still planned. Evidence · text > at laboratory scale **Single Domain Only** Polarity: negative Definition: Testing limited to one composite or domain — representativeness not established. Why it applies: The programme was undertaken on a single composite representative of Grandao stage 1, so domain coverage is limited. Evidence · text > undertaken on a single composite **Recovery Improving** Polarity: positive Definition: Recovery improved versus a like-for-like prior test program on the same domain and route. Why it applies: The final LCT results are described as better than the earlier variability programme, which achieved 70%-79.5% Li2O recoveries. Evidence · text > improved levels of recoveries are achievable **QA/QC Disclosed** Polarity: positive Story-specific tag Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\). Why it applies: The release names competent persons and describes the supervised test programme, but it does not provide assay QA/QC methods for laboratory control. Evidence · text > The LCT programme was supervised by MinSol Engineering Pty Ltd **Gravity Route** Polarity: neutral Definition: Gravity separation forms a material part of the flowsheet. Why it applies: the document describes a gravity route \("dense media separation"\) ## Extracted facts Stored fact records: 7.

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.
