## Minestarters Atlas summary

Quantum Critical Metals has initiated an advanced metallurgical testing program at its NMX East project in Québec to optimize rubidium recovery. The program, conducted in collaboration with the University of British Columbia, aims to develop a hydrometallurgical flowsheet for rubidium, gallium, tantalum, and lithium.

Reasoning: The company is initiating a metallurgical program to optimize recovery of high-value critical minerals, supported by high-grade enrichment data in mica concentrates.

- Positive factor: Initiation of advanced metallurgical test work

- Positive factor: High-grade mica concentrate enrichment confirmed

- Positive factor: Engagement of recognized academic expert \(UBC\)

- Positive factor: Strategic focus on high-value critical minerals

- Negative factor: Early stage of metallurgical testing \(scoping/preliminary\)

- Negative factor: No recovery percentages yet reported

Facts used in scoring: 4

## Classification and evidence

**Bench Scale Only**

Polarity: negative

Definition: Only preliminary bench tests completed — no locked-cycle or pilot work.

Why it applies: The company is just initiating metallurgical testing to evaluate a flowsheet, which is at a preliminary/scoping stage.

## 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.
