## Minestarters Atlas summary

Green Battery Minerals has successfully completed a dry air separation test for its Berkwood graphite property using Volt Carbon Technologies' proprietary process. The test yielded high-grade graphite \(91.55% C\) and preserved large/jumbo flake sizes, offering a more environmentally friendly and potentially lower-cost alternative to traditional chemical purification.

Reasoning: Successful pilot-scale metallurgical test using a novel solventless air separation process, yielding high-grade graphite \(91.55% C\) while preserving large flake size, verified by an independent lab.

- Positive factor: Successful dry separation test

- Positive factor: High graphite grades achieved

- Positive factor: Maintains flake size distribution

- Positive factor: ESG/Green credentials improvement

- Positive factor: Third-party verification provided

Facts used in scoring: 2

## Classification and evidence

**High Recovery**

Polarity: positive

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

Why it applies: The process yielded 146g of graphite per kg of feedstock \(14.6% yield\) with high concentrate grades.

Evidence · text

> reflecting a of 14.6% yield of graphite flakes per kg of feedstock

**Free Milling**

Polarity: positive

Definition: Simple, clean ore amenable to standard processing without oxidation.

Why it applies: The process is described as solventless and reagentless, implying simple processing of the graphite.

Evidence · text

> omitting the use of solvents and does not produce contaminated liquid waste

**QP/CP Signed**

Polarity: positive

Story-specific tag

Definition: Qualified Person \(QP\) or Competent Person \(CP\) named and signed off — a member of a recognized professional association \(e.g., AusIMM, SME, AIG, P.Geo\) with relevant experience.

Why it applies: Christian Derosier, P.Geo., PhD., is named as the Qualified Person who reviewed and approved the release.

Evidence · text

> Qualified Person Christian Derosier, P.Geo., PhD., is the qualified person \(QP\)

## 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.
