## Minestarters Atlas summary

LithiumBank has successfully completed DLE pilot testing on its Boardwalk and Park Place brines using SLB technology, achieving up to 95% lithium recovery and over 99% impurity rejection. The results support the technical compatibility of the projects with the integrated SLB production solution.

Reasoning: The pilot test results demonstrate high technical viability for the DLE process on both target brines, with strong recovery and impurity rejection metrics.

- Positive factor: High lithium recovery \(up to 95%\)

- Positive factor: Exceptional impurity rejection \(>99%\)

- Positive factor: Pilot scale testing completed

- Positive factor: QP sign-off provided

- Negative factor: Pilot scale results may not scale linearly to commercial

- Negative factor: Third-party verification of brine composition/density not obtained

Facts used in scoring: 6

## Classification and evidence

**High Recovery**

Polarity: positive

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

Why it applies: Lithium recovery of 94.5-95% is exceptional for DLE processes.

Evidence · text

> successfully recovered up to 95% of lithium

**QP/CP Signed**

Polarity: positive

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: George Brindle, P.Eng. is named as the Qualified Person who reviewed the metallurgical testing.

Evidence · text

> consent to publicly disclose this data is provided by George Brindle, P.Eng.

**Inferred Resource**

Polarity: negative

Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone.

Why it applies: A significant portion of the reported resource is in the Inferred category.

## 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.
