A thid round of HPA testing on Carey's Well halloysite-kaolin has confirmed that 4N (99.99%) purity is achievable with only a single purification stage which compares very favourably to HPA peers requiring multiple stages and which may correlate to significantly lower capital and operating costs

HPA testing confirms premium grade feed potential at Poochera

Additional Third Round of HPA testing on Poochera halloysite-kaolin has confirmed that 4N (99.99%) purity is achievable with only a single purification stage. This compares favourably to peer companies which require multiple purification stages to reach 4N puirty.

The result represents the potential to significantly reduce capital requirements and operating costs for any HPA processing plant.

Achieving a 5N (99.999%) purity test result has proved to be impractical at this point in time due to equipment and laboratory limitations.

Discussions are in progress with a Chinese company regarding the use of halloysite-kaolin for HPA production in China.

In addition to the HPA testing, ADN continues to advance the Poochera Halloysite-Kaolin Project following the successful dry processing of a bulk sample in Australia.

A shipment of 140 tonnes of raw ore has now arrived in China to be processed through a wet-processing plant with results expected during March. Final processed product is then to be provided to potential end-use ceramic customers for commercial evaluation.

Scoping Study work is progressing with mine design and logistic studies well underway.
