Summary
U3O8 Corp. reported metallurgical test results for its Laguna Salada project in Argentina, showing a 23% improvement in overall vanadium extraction and a 2% improvement in uranium extraction compared to the 2014 PEA. The work, conducted at ANSTO, suggests a simplified flowsheet using coarser 0.85mm material could reduce processing time and capital costs.
Reasoning: The test work demonstrates significant improvements in overall metal recovery and potential for cost reduction through flowsheet simplification compared to the 2014 PEA.
Positive factors
- Improved vanadium overall extraction by 23% vs PEA
- Improved uranium overall extraction by 2% vs PEA
- Simplified flowsheet with reduced scrubbing residence time
- Coarser material (0.85mm) potentially reduces filtration costs
Negative factors
- Vanadium extraction from the fine-grained component (55%) was lower than the PEA model (71%)
Facts used in scoring: 2
Classification and evidence
Mill Routeneutral
Processing via mill or concentrator (CIL, CIP, tank leach, flotation).
Why it applies: The test work involves alkaline leaching and scrubbing/screening processes.
Evidence · text
“Alkaline leach extracted 94% of the contained uranium”
Single Domain Onlynegative
Testing limited to one composite or domain — representativeness not established.

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.
