## Minestarters Atlas summary

Mount Ridley Mines reported a metallurgical breakthrough at its Grass Patch Complex in WA using its proprietary Selectro process. The process achieved high recoveries for heavy rare earths, scandium, and gallium, significantly outperforming standard hydrochloric acid leaching.

Reasoning: The company reported a metallurgical breakthrough using a proprietary process that significantly outperforms standard leaching methods for multiple critical minerals.

- Positive factor: Proprietary Selectro process doubling industry standard recovery

- Positive factor: High recovery of high-value heavy rare earths \(dysprosium, terbium\)

- Positive factor: Significant scandium and gallium recovery improvements

Facts used in scoring: 13

## Classification and evidence

**High Recovery**

Polarity: positive

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

Why it applies: Scandium recovery of 80% is exceptional for the context.

Evidence · text
