## Minestarters Atlas summary

Ucore Rare Metals Inc. has announced the successful acceptance of its Phase 1 Final Report and Techno-Economic Assessment by the US Department of War. The reports confirm that the RapidSX™ technology achieved REE recovery and purity levels comparable to conventional solvent extraction while offering a 34% reduction in CAPEX and a 60% smaller footprint.

Reasoning: The document reports successful metallurgical demonstration of a proprietary separation technology, providing de-risking for the upcoming commercial project in Louisiana.

- Positive factor: Successful completion of Phase 1 DoW demonstration program

- Positive factor: RapidSX technology matched conventional SX on purity and recovery

- Positive factor: Significant CAPEX reduction \(34%\) and footprint reduction \(60%\) demonstrated

- Positive factor: Operational flexibility \(start/stop/reconfigure\) validated

Facts used in scoring: 3

## Classification and evidence

**Mill Route**

Polarity: neutral

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

Why it applies: The technology involves solvent extraction \(SX\) circuit processing.

Evidence · text

> reconfigure stages in SX circuit within hours

**High Recovery**

Polarity: positive

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

Why it applies: Recovery was reported as virtually identical to or better than the conventional baseline 13 times out of 14.

Evidence · text

> Recovery Virtually identical - better than or similar to CSX 13 times out of 14

**Multi-Domain Tested**

Polarity: positive

Definition: Variability across ore domains \(oxide, transition, fresh\) has been addressed.

Why it applies: 2 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.
