The bench-scale tests achieved a 92.98% tungsten recovery, upgrading a 0.35% WO3 bulk sample to a 7.21% WO3 rougher concentrate. Reasoning: The announcement reports highly encouraging initial metallurgical results from bench-scale flotation tests, demonstrating high recovery and significant grade upgrading for the Defender Tungsten Project. - Positive factor: High tungsten recovery \(92.98%\) - Positive factor: Significant grade upgrade \(0.35% to 7.21% WO3\) - Positive factor: Low levels of deleterious molybdenum - Positive factor: Successful sulphide removal pre-treatment - Negative factor: Preliminary results subject to third-party assay verification - Negative factor: Bench-scale test work only Facts used in scoring: 2 ## Classification and evidence **High Recovery** Polarity: positive Definition: Recovery at or above the exceptional band for the commodity and processing route. Why it applies: Tungsten recovery of 92.98% is in the exceptional/strong tier for flotation. Evidence · text > 92.98% of the tungsten was recovered **Bench Scale Only** Polarity: negative Definition: Only preliminary bench tests completed — no locked-cycle or pilot work. Why it applies: Results are from bench-scale flotation test work. Evidence · text > bench-scale flotation test work **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: The process uses flotation methods. Evidence · text > established flotation methods **Single Domain Only** Polarity: negative Definition: Testing limited to one composite or domain — representativeness not established. Why it applies: only one composite was tested ## Extracted facts Stored fact records: 2.

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.
