## 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 demonstrate high compatibility with the integrated solution and provide a basis for scaling to a commercial-scale unit.

Reasoning: The announcement reports successful pilot-scale DLE testing with high recovery and impurity rejection, significantly de-risking the technical path for the Boardwalk and Park Place projects.

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

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

- Positive factor: Successful pilot testing of DLE technology

- Positive factor: QP verification of data

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

- Negative factor: Pilot scale results require longer runs to confirm sorbent lifespan

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 reached 94.5% and 95.0% which is in the exceptional band for lithium.

Evidence · text

> successfully recovered up to 95% of lithium from both Park Place and Boardwalk

**QA/QC Disclosed**

Polarity: positive

Story-specific tag

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

Why it applies: The release includes QP sign-off and mentions verification of sampling and analytical data.

Evidence · text

> The data disclosed, including sampling, analytical, and test data underlying this announcement have been verified by the QP

**Bench Scale Only**

Polarity: negative

Definition: Only preliminary bench tests completed — no locked-cycle or pilot work.

Why it applies: The results are from a pilot campaign, which is a step above bench but below commercial scale.

Evidence · text

> Piloting results can be used to determine operating parameters for a ~25,000 cubic metres \(m 3 \) per day commercial scale DLE unit

**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.
