## Minestarters Atlas summary

Mount Ridley Mines has reported successful metallurgical test results for its Selectro™ program, achieving 91.8% scandium recovery. Notably, the recovery was achieved using half the reagent required previously and operated at atmospheric pressure on unbeneficiated ore.

Reasoning: The announcement reports high scandium recovery using significantly reduced reagent consumption at atmospheric pressure, which is a strong positive signal for processing economics.

- Positive factor: High scandium recovery \(91.8%\)

- Positive factor: Reduced reagent consumption \(half the reagent\)

- Positive factor: Atmospheric pressure leach \(lower complexity/capex\)

- Positive factor: Tested on unbeneficiated ore

Facts used in scoring: 1

## Classification and evidence

**High Recovery**

Polarity: positive

Definition: Recovery at or above the exceptional band for the commodity and processing route.

Why it applies: 91.8% scandium recovery is reported, which is exceptionally high for a leach process.

Evidence · text

> reports 91.8% scandium recovery

**Mill Route**

Polarity: neutral

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

Why it applies: The test used atmospheric pressure leaching on unbeneficiated ore, implying a standard hydrometallurgical route.

Evidence · text

> best recoveries at atmospheric pressure, on unbeneficiated ore

**Single Domain Only**

Polarity: negative

Definition: Testing limited to one composite or domain — representativeness not established.

Why it applies: only one composite was 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.
