Ann: HPA Testing Confirms Premium Grade Feed Potential, page-2

Summary
 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 purity.
 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 or 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.
Discussion
Andromeda Metals (ASX: ADN) is pleased to announce the results of enhanced
HPA metallurgical testing of Carey’s Well halloysite‐kaolin from the Poochera
Project after the previous Second Round showed that 4N purity could be
achieved with only one stage of purification.
Round One preliminary testing carried out by Bureau Veritas, UniSA and the
University of Newcastle achieved a purity of 99.9855% from an over‐refined
sample where impurities had been introduced. An industry standard HCL
(Hydrochloric Acid) two‐stage dissolution/precipitation purification process
was used for this work (refer ADN ASX Release 30th May 2018).
