The tests achieved a 92.98% tungsten recovery, upgrading a 0.35% WO3 bulk sample to a 7.21% WO3 rougher concentrate with low levels of deleterious molybdenum. Reasoning: The results demonstrate high recovery and significant grade upgrading from a bulk sample using standard flotation methods, providing a strong technical foundation for the project. - Positive factor: High tungsten recovery \(92.98%\) - Positive factor: Substantial grade upgrade \(0.35% to 7.21% WO3\) - Positive factor: Low levels of deleterious molybdenum - Positive factor: Successful sulphide 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 exceptional for the reported flotation process. 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 on a 750 kg bulk sample. Evidence · text > initial metallurgical results from bench-scale flotation test work **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: the document describes a flotation route \("flotation"\) **Multi-Domain Tested** Polarity: positive Definition: Variability across ore domains \(oxide, transition, fresh\) has been addressed. Why it applies: 2 distinct composites were 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.
