Minestarters Atlas analysis
Summary
Lake Victoria Gold has identified attrition scrubbing and desliming as the preferred pretreatment route for the clay-rich, near-surface mineralization at the Imwelo Gold Project. This pretreatment increased 24-hour gold extraction from 49.99% to 84.54% and improved slurry settling and gravity recovery.
Reasoning: The metallurgical testwork successfully identified a pretreatment route (attrition scrubbing and desliming) that significantly boosts gold extraction from ~50% to ~85% for the clay-rich near-surface ore at Area C.
Positive factors
- Significant recovery improvement via pretreatment
- Improved slurry handling characteristics
- Strong gravity-recoverable gold results
- QA/QC disclosed with certified lab and QP sign-off
Negative factors
- Results are from pretreated fractions and do not yet represent whole-ore plant recovery
Facts used in scoring: 5
Classification and evidence
High Recoverypositive
Recovery at or above the exceptional band for the commodity and processing route.
Why it applies: Attrition scrubbed and deslimed fraction returned 88.15% recovery in bottle roll testing.
Evidence · text
“Bottle-roll recovery of up to 88.15%”
Mill Routeneutral
Processing via mill or concentrator (CIL, CIP, tank leach, flotation).
Why it applies: The program evaluated cyanide leaching and CIL (Carbon-in-Leach) processes.
Evidence · table
“CIL – 25 g/L carbon”
Context: 3.80
Gravity Routeneutral
Gravity separation forms a material part of the flowsheet.
Why it applies: the document describes a gravity route ("gravity")
Multi-Domain Testedpositive
Variability across ore domains (oxide, transition, fresh) has been addressed.
Why it applies: 3 distinct composites were tested

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.
