## Minestarters Atlas summary

Renascor has successfully produced battery-grade purified spherical graphite \(PSG\) with 99.97% carbon purity at its demonstration plant in Adelaide. This milestone validates the scale-up of their HF-free purification process using third-party graphite to establish performance benchmarks.

Reasoning: Successful demonstration-scale production of battery-grade purified spherical graphite \(PSG\) validates the company's proprietary HF-free technology.

- Positive factor: Achieved battery-grade purity \(99.97% C\) at demonstration scale

- Positive factor: Validates HF-free purification process scale-up

- Positive factor: Supports customer engagement and offtake discussions

- Positive factor: Uses third-party graphite to benchmark performance

- Negative factor: Trials used third-party graphite rather than Siviour graphite for this specific milestone

Facts used in scoring: 1

## Classification and evidence

**Mill Route**

Polarity: neutral

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

Why it applies: The process involves an integrated purification circuit/flowsheet at a demonstration plant.

Evidence · text

> integrated purification flowsheet

**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.
