The work utilized a coarser 0.85mm material which suggests potential for simplified processing and reduced capital costs. Reasoning: The test work demonstrates significant improvements in overall vanadium and uranium recovery by using a coarser \(0.85mm\) material compared to the 2014 PEA model, while also suggesting potential for CAPEX/OPEX reduction through process simplification. - Positive factor: Improved vanadium recovery vs PEA - Positive factor: Improved uranium recovery vs PEA - Positive factor: Process simplification potential - Positive factor: Coarser grain size testing reduces filtration complexity - Negative factor: Vanadium extraction from fine-grained component is lower than PEA model - Negative factor: Sulphate management remains a cost priority Facts used in scoring: 4 ## Classification and evidence **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 mentions the work was designed and monitored by a director with significant technical experience and refers to a QP \(Dr. Richard Spencer\) approving 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.
