Minestarters Atlas analysis
Summary
Verde AgriTech has confirmed ionic-adsorption behaviour at the Minas Americas Project through SGS screening leach tests. The tests demonstrated high-value magnet rare earth oxide (MREO) enrichment in leachate (up to 278 mg/kg) with exceptionally low thorium and uranium levels.
Reasoning: The release confirms high-value magnet REE enrichment in leachate with very low radioactive contaminants, a key technical de-risking milestone for ionic clay projects.
Positive factors
- High-value magnet REE enrichment in leachate (>40% MREO)
- Exceptionally low thorium and uranium contaminants (below detection)
- Selective desorption of magnet REEs over cerium
- Confirmed ionic-adsorption behaviour via SGS screening
Negative factors
- Preliminary screening-level testwork (single short contact)
- Results are from early-stage trenching, not a full resource
Facts used in scoring: 6
Classification and evidence
Free Millingpositive
Simple, clean ore amenable to standard processing without oxidation.
Why it applies: The release describes ionic-adsorption behaviour with easy desorption under mild ammonium-sulfate leaching conditions.
Evidence · text
“demonstrating strong magnet-REE proportion in these initial tests. ... ambient-condition desorption”
Bench Scale Onlynegative
Only preliminary bench tests completed — no locked-cycle or pilot work.
Why it applies: The metallurgical results are from a 30-minute screening test (bottle roll style) rather than pilot or locked-cycle work.
Evidence · text
“Under the diagnostic 0.5 M ammonium-sulfate, 30-minute leach screen”
Mill Routeneutral
Processing via mill or concentrator (CIL, CIP, tank leach, flotation).
Why it applies: the document describes a flotation route ("concentrate")
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.
