Minestarters Atlas analysis
Summary
Great Western Mining Corporation has announced successful bench-scale flotation test results for its Defender Tungsten Project in Nevada. The tests achieved a 92.98% tungsten recovery, upgrading a 0.35% WO3 bulk sample to a 7.21% WO3 rougher concentrate.
Reasoning: The results demonstrate high recovery and significant grade upgrading using standard flotation, which is a strong technical milestone for the Defender project.
Positive factors
- High tungsten recovery (92.98%)
- Significant grade upgrade (0.35% to 7.21% WO3)
- Low levels of deleterious molybdenum
- Successful sulphide removal pre-treatment
Negative factors
- Preliminary results subject to third-party assay verification
- Bench-scale testwork only
Facts used in scoring: 2
Classification and evidence
High Recoverypositive
Recovery at or above the exceptional band for the commodity and processing route.
Why it applies: 92.98% tungsten recovery is excellent for preliminary flotation test work.
Evidence · text
“92.98% of the tungsten was recovered”
Bench Scale Onlynegative
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 Routeneutral
Processing via mill or concentrator (CIL, CIP, tank leach, flotation).
Why it applies: the document describes a flotation route ("flotation")
Multi-Domain Testedpositive
Variability across ore domains (oxide, transition, fresh) has been addressed.
Why it applies: 2 distinct composites were tested

Reasoning: The pre-float stage successfully retained almost all tungsten while removing contaminants.
Positive factors
- Minimal loss of target mineral during sulphide removal
Evidence · text
“The pre-float phase retained 99.46% of the tungsten within the main sink stream at a grade of 0.35% WO3”

How Atlas produces this analysis
Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. 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.
