Test work to date shows spodumene concentrate grading at least 5.5% Li2O, with average recoveries of 75.3% at a 150 micron grind and a range of 70-79.5% across the variability programme. The company also says locked-cycle and pilot plant test work are now underway. Reasoning: This is a positive metallurgical milestone: the process flowsheet has been finalised for DFS work and test work shows acceptable spodumene concentrate grade and solid recoveries. The release is still interim for the variability programme, so some novelty remains incomplete and the technical risk around the unique reagent regime is not fully eliminated. - Positive factor: flowsheet finalised for Barroso Lithium Project - Positive factor: recovery improved to 75.3% average at 150 micron - Positive factor: spodumene concentrate grading ≥5.5% Li2O - Positive factor: industry standard equipment and processes - Positive factor: locked cycle and pilot plant testing underway - Negative factor: two of ten variability samples still to be finalised - Negative factor: full results will be summarised in a subsequent release - Negative factor: uniqueness of mica flotation reagent regime noted as a technical risk Facts used in scoring: 9 ## Classification and evidence **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: The flowsheet uses magnetic separation and flotation, which places the process in the mill/concentrator category. Evidence · text > followed by magnetic separation and flotation **Free Milling** Polarity: positive Definition: Simple, clean ore amenable to standard processing without oxidation. Why it applies: The release describes a conventional spodumene processing flowsheet with industry standard technologies and no refractory issue. Evidence · text > The process flowsheet developed for the Barroso Lithium Project is conventional **Multi-Domain Tested** Polarity: positive Definition: Variability across ore domains \(oxide, transition, fresh\) has been addressed. Why it applies: The ore variability programme used 10 composites representing each major resource zone and lithology. Evidence · text > utilised 10 composites, representing each major resource zone and lithology **Pilot Scale Complete** Polarity: positive Definition: Pilot or demonstration plant testing completed under continuous operation. Why it applies: The release says locked cycle test work and pilot plant test work programmes are underway, but not yet complete; this tag is not applied. Evidence · text > Locked Cycle Testing **No QA/QC Disclosure** Polarity: negative Story-specific tag Definition: Release does not disclose QA/QC — lab certification, CP/QP sign-off and assay protocols cannot be checked from this document. Why it applies: The announcement identifies laboratories and competent persons, but it does not set out blanks, standards or duplicate procedures for the metallurgical assays in this release. Evidence · text > The information in this release that relates to metallurgy and metallurgical test work has been reviewed by Mr Robert Simmons **True Width Disclosed** Polarity: positive Story-specific tag Definition: Actual thickness perpendicular to structure is stated, not just downhole length. Why it applies: No true width is relevant here because this is metallurgical test work rather than drilling; no drill width claim is made. Evidence · text > Finalisation of Environmentally Enhanced Process Flowsheet **Positive flowsheet finalisation** Polarity: positive Story-specific tag Definition: No canonical definition is currently available. Why it applies: The flowsheet is said to be finalised and ready to be adopted for detailed engineering studies as part of the DFS. Evidence · text > now finalised and ready to be adopted for detailed engineering studies ## Extracted facts Stored fact records: 9.

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.
