Analysis by Minestarters Atlas

Minestarters Atlas analysis

Summary

Green Battery Minerals and Volt Carbon have successfully progressed the air separation of a bulk sample from the Berkwood property, achieving graphite concentrate grades of up to 96.1% Cg. The proprietary solvent-free dry separation process is being scaled up, with samples now being sent to prospective customers for battery-grade assessment.

Reasoning: Successful metallurgical testing of a bulk sample demonstrating high-grade graphite concentrate using a novel, environmentally friendly dry separation process.

Positive factors

  • High grade concentrate achieved (96.1% Cg)
  • Successful dry separation process (solvent-free)
  • Scale-up of proprietary technology progressing
  • High grade feedstock (up to 71.6% Ct)

Negative factors

  • Results are from a small bulk sample (200kg processed to date)

Facts used in scoring: 4

Classification and evidence

QA/QC Disclosedpositive · Story-specific tag

Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods (blanks, standards, duplicates).

Why it applies: Release mentions CRM insertion, field duplicates, and SGS laboratory submission.

Evidence · text

“a CRM sample was inserted at a ratio of 1 sample in 20 to the sample batch, field duplicates were additionally collected”

NI 43-101 Compliantpositive

Resource estimate prepared in compliance with NI 43-101 (Canada) — high reporting standard.

Why it applies: The resource estimate is described as being contained in an NI 43-101 Technical Report.

Evidence · text

“described in the technical report entitled, NI 43-101 Technical Report”

Stale Estimatenegative

Effective date is >2 years old — data currency concern, may not reflect current geological understanding.

Why it applies: The resource estimate provided in the table is dated June 2019, which is more than 2 years old.

Evidence · text

“Current Resources (as of June 17 th , 2019)”

Mill Routeneutral

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

Why it applies: the document describes a flotation route ("flotation")

Single Domain Onlynegative

Testing limited to one composite or domain — representativeness not established.

Why it applies: only one composite was tested

Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.

Why it applies: cutoff_grade is stated

QP/CP Signedpositive

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: qp_signed is true

NI 43-101 Compliantpositive

Resource estimate prepared in compliance with NI 43-101 (Canada) — high reporting standard.

Why it applies: reporting_standards includes ni_43_101

No Contained Metalnegative

Tonnage and grade reported but contained metal not calculated or disclosed — incomplete reporting.

Why it applies: contained_metal was not reported

Stale Estimatenegative

Effective date is >2 years old — data currency concern, may not reflect current geological understanding.

Why it applies: effective date is 4.3 years before this release

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.
