The tests demonstrated that screening the channel sands at 0.5mm effectively pre-concentrates uranium and vanadium while rejecting the majority of reagent-consuming gypsum. Reasoning: Beneficiation tests confirmed that screening at 0.5mm can capture 88% of uranium and 76% of vanadium while rejecting 94% of gypsum, significantly improving potential economics compared to the previous PEA model. - Positive factor: successful pre-concentration via scrubbing/screening - Positive factor: effective rejection of reagent-consuming gypsum - Positive factor: higher metal capture in fine fractions compared to previous gravel model - Negative factor: high proportion of metals rejected in the finest fraction \(0.01mm\) would reduce revenue Facts used in scoring: 4 ## Classification and evidence **Free Milling** Polarity: positive Definition: Simple, clean ore amenable to standard processing without oxidation. Why it applies: The document describes the sand as 'soft, channel-fill sands' that can be processed via simple scrubbing and screening. Evidence · text > beneficiation test work on soft, channel-fill sands **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: The process involves scrubbing in a rotating drum and vibrating stacked screens. Evidence · text > the sand was scrubbed in a rotating drum for two minutes and was run through a set of vibrating stacked screens ## Extracted facts Stored fact records: 4.

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.
