Summary
Argenta Silver reported successful initial flotation testwork at the El Quevar project in Argentina, achieving silver recoveries up to 96% and a high-grade cleaner concentrate of 14,857 g/t Ag. The results from the Yaxtché deposit demonstrate that a conventional flotation flowsheet is viable, though optimization and locked-cycle testing are still ongoing.
Reasoning: Initial metallurgical testwork shows very high silver recoveries and exceptional concentrate grades, significantly de-risking the processing potential of the Yaxtché deposit.
Positive factors
- High silver recoveries in rougher flotation (up to 99%)
- Exceptional cleaner concentrate grade (14,857 g/t Ag)
- Strong cleaner recovery (96%)
- Demonstrates conventional flowsheet potential
Negative factors
- Preliminary/early-stage results
- Optimization and locked-cycle testing not yet completed
- Deleterious element concentrations not yet reliably assessed
Facts used in scoring: 17
Classification and evidence
High Recoverypositive
Recovery at or above the exceptional band for the commodity and processing route.
Why it applies: Achieved silver recoveries up to 99% in rougher flotation and 96% in cleaner flotation.
Evidence · text
“achieving up to 96% Ag recovery”
Bench Scale Onlynegative
Only preliminary bench tests completed — no locked-cycle or pilot work.
Why it applies: Results are from initial variability and cleaner flotation tests, described as early-stage and preliminary.
Evidence · text
“The reported results represent an early stage of the metallurgical testwork program and are preliminary”
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.
