## Minestarters Atlas 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 factor: High-value magnet REE enrichment in leachate \(>40% MREO\)

- Positive factor: Exceptionally low thorium and uranium contaminants \(below detection\)

- Positive factor: Selective desorption of magnet REEs over cerium

- Positive factor: Confirmed ionic-adsorption behaviour via SGS screening

- Negative factor: Preliminary screening-level testwork \(single short contact\)

- Negative factor: Results are from early-stage trenching, not a full resource

Facts used in scoring: 6

## Classification and evidence

**Free Milling**

Polarity: positive

Definition: 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 Only**

Polarity: negative

Definition: 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 Route**

Polarity: neutral

Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\).

Why it applies: the document describes a flotation route \("concentrate"\)

**Multi-Domain Tested**

Polarity: positive

Definition: 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.
