Summary
Argenta Silver has reported successful initial flotation testwork at the El Quevar project in Argentina, achieving silver recoveries of up to 96% in cleaner stages. The tests produced a high-grade silver concentrate of 14,857 g/t Ag, demonstrating the potential for a conventional flotation flowsheet.
Reasoning: Initial flotation tests at El Quevar show exceptional silver recoveries and high-grade concentrate, significantly de-risking the metallurgical potential of the Yaxtché deposit.
Positive factors
- High silver recoveries (up to 99% in rougher, 96% in cleaner)
- Very high grade concentrate (14,857 g/t Ag)
- Standard industrial flowsheet demonstrated
- QA/QC protocols and independent lab (Blue Coast Research) mentioned
Negative factors
- Preliminary results, not yet optimized
- Final concentrate mineralogy and deleterious elements not yet assessed
- Locked-cycle testing not yet completed
Facts used in scoring: 17
Classification and evidence
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: 15 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.
