Analysis by Minestarters Atlas
Minestarters Atlas analysis
Summary
Green Battery Minerals has successfully completed a dry air separation test of its Berkwood graphite using Volt Carbon Technologies' proprietary process. The test yielded 91.55% graphite content and preserved large/jumbo flake sizes, offering a greener, solventless alternative to traditional purification methods.
Reasoning: Successful metallurgical testwork using a novel dry separation process yielded high-grade graphite (91.55% C) while preserving premium flake size, verified by an independent lab.
Positive factors
- Successful dry separation test
- High graphite grades achieved
- Maintains large/jumbo flake size
- ESG positive (solventless/reagentless)
- Third-party verification provided
Facts used in scoring: 2
Classification and evidence
Free Millingpositive
Simple, clean ore amenable to standard processing without oxidation.
Why it applies: The process is described as a dry, solventless separation of graphite flakes.
Evidence · text
“The new process utilizes air as its separation medium, thereby omitting the use of solvents”
Single Domain Onlynegative
Testing limited to one composite or domain — representativeness not established.
Why it applies: only one composite was 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.
