Ann: Andromeda Progresses HPA Strategy, page-2

Highlights
 Testing results from AEM’s HPA pilot test facility in Canada have
confirmed Great White halloysite-kaolin as a premium grade feed
material for the HPA production process
 Positively the incredibly low levels of specific impurities in
Andromeda supplied feed indicates that approx. 3 tonnes of Great
White Feed will produce approx. 1 tonne of 4N or better HPA
whereas the normal ratio is about 10:1.
 Andromeda has engaged global expert Dr Bryn Harris assisted by
Dr Mike Dry to lead the Company’s HPA strategy and to augment
work being done in Australia by HPA expert Boyd Willis
 Bryn will oversee the ongoing due diligence on Advanced
Engineering Materials (AEM) and their plans for a HPA plant in the
UK and testing of Andromeda’s Eyre Peninsula kaolins
 The MOU with AEM has been extended until Dec 31st 2021 to further
advance AEM’s UK HPA project that is in the Feasibility Study phase
and which Andromeda is planning to replicate, and also to
complete due diligence on the modular plant design
 AEM is a global leader in HPA and operates a HPA plant in Canada
capable of producing HPA at 4N (99.99%) and 5N (99.999%) purity
 A large amount of Mount Hope kaolin has been collected and
refined in preparation for testing to determine its suitability as HPA
feed as this resource contains some very high purity material
