## Minestarters Atlas summary

GreenRoc corrected its graphite concentrate grade to 95.2% following locked-cycle testing by SGS Lakefield, which also showed >90% recovery. The company has selected GTK Mintec to process a 20-tonne bulk sample and has completed an underground survey of the Amitsoq mine to support a future Pre-Feasibility Study.

Reasoning: The announcement provides corrected, high-quality metallurgical results \(95.2% grade, >90% recovery\) and advances the project toward bulk testing and PFS via underground survey.

- Positive factor: High graphite concentrate grade \(95.2%\)

- Positive factor: Strong recovery \(>90%\)

- Positive factor: Selection of GTK Mintec for bulk testing

- Positive factor: Successful underground survey

- Negative factor: Correction to previously reported percentage \(92.3% to 95.2%\)

- Negative factor: Drilling delay due to helicopter availability

Facts used in scoring: 1

## Classification and evidence

**High Recovery**

Polarity: positive

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

Why it applies: Graphite recovery of more than 90% is reported.

Evidence · text

> overall recovery of more than 90%

**Mill Route**

Polarity: neutral

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

Why it applies: The test work involved crushing, grinding, and flotation.

Evidence · text

> series of grinding and flotation tests began in April 2026

**Single Domain Only**

Polarity: negative

Definition: 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.
