## Minestarters Atlas summary

Ucore Rare Metals has successfully produced 99.5% pure neodymium-praseodymium \(NdPr\) from both ionic clay and bastnaesite feedstocks at its Kingston, Ontario facility. This demonstration validates the versatility of its RapidSX technology platform ahead of commercial development at the Louisiana Strategic Metals Complex.

Reasoning: Successful demonstration of high-purity NdPr recovery from two distinct feedstock types \(ionic clay and bastnaesite\) validates the company's proprietary RapidSX technology.

- Positive factor: demonstrated technical ability to process different feedstocks

- Positive factor: high-purity product achieved \(99.5%\)

- Positive factor: technology platform \(RapidSX\) validated in simulated commercial environment

Facts used in scoring: 2

## Classification and evidence

**Mill Route**

Polarity: neutral

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

Why it applies: The process involves solvent extraction \(RapidSX\) at a demonstration facility.

Evidence · text

> Ucore's RapidSX technology chemistry is the same as that of conventional solvent extraction

## 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.
