Minestarters Atlas analysis
Summary
Lake Victoria Gold has identified attrition scrubbing followed by desliming as the preferred pretreatment route for the clay-rich near-surface mineralization at the Imwelo Gold Project. This process increased 24-hour gold extraction from 49.99% to 84.54% and improved slurry settling and gravity recovery. The results complement existing high-recovery data for deeper transitional and fresh mineralization.
Reasoning: The identification of a preferred pretreatment route (attrition scrubbing and desliming) significantly lifts gold extraction from ~50% to ~85% for the clay-rich near-surface material, addressing a key technical risk for the early mining sequence.
Positive factors
- Significant recovery improvement via pretreatment
- Improved slurry handling characteristics
- Confirmed coarse gold/gravity potential
- QA/QC disclosed with certified lab and QP sign-off
Negative factors
- Results represent pretreated fractions, not 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/deslimed fraction achieved 84.54% 24h extraction and 88.15% bottle roll recovery.
Evidence · text
“84.54% following attrition scrubbing and desliming”
QA/QC Disclosedpositive · Story-specific tag
Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods (blanks, standards, duplicates).
Why it applies: Release mentions certified reference materials and blanks were used in testing.
Evidence · text
“Certified reference materials and a blank were inserted with the samples”
Mill Routeneutral
Processing via mill or concentrator (CIL, CIP, tank leach, flotation).
Why it applies: the document describes a mill_cil route ("CIL")
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

Reasoning: Baseline recovery on as-received material is low (49.99%) due to the clay-rich nature of the near-surface ore.
Negative factors
- Low baseline recovery due to clay content

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.
