AMMG produces high-purity alumina

THE BOURSE WHISPERER: Australia Minerals and Mining Group (AMMG) (ASX: AKA) claims to have produced over 99.9 per cent of high-purity alumina (HPA).

The company explained it has achieved this using its own unique aluminous clay (kaolin) to alumina processing technology.

AMMG used samples from all four of its South West HPA projects in Western Australia, which the company said proved to be a clean source of aluminous clay for HPA production using its process.

“Our unique technology varies from other aluminous clay to alumina technologies in that it uses substantially less energy; the process uses low temperatures and pressures,” Australia Minerals and Mining Group managing director Ric Dawson said in the company’s announcement to the Australian Securities Exchange.

“This innovative processing technology produces minimal waste and the key reagents are recyclable, therefore, the efficiencies are high.

“The successful testing should now build on the level of interest the company has received to date.

“HPA is a premium high-value product that is used in high-performance electronic applications, such as tablet screens and LED’s.”

AMMG’s 100 per cent-owned South West HPA project is held by its wholly-owned subsidiary Kaolin Resources.

The project consists of one granted exploration licence and nine applications, where the company is targeting aluminous clay in the south west of Western Australia and in the Yilgarn mineral belt: Meckering, Kerrigan, Kellerberrin and Bobalong.

AMMG has delineated two separate resources on its Meckering and Kerrigan aluminous clay projects, totalling 150 million tonnes with screened grades of up to 38 per cent alumina, and an exploration target ranging from 485 million tonnes to 830 million tonnes.

The resource is made up of 85 million tonnes (inferred) at the Kerrigan project and 65 million tonnes (16.77 million tonnes indicated and 48.28 million tonnes inferred) at the Meckering project.

The company indicated it is currently planning its next phase of exploration in order to increase this resource.
