Australia Minerals and Mining Group (AMMG) has acquired the Gibson aluminous clay project in Esperance, Western Australia, thereby increasing its clay resources to 297 million tonnes.

The purchase was made through AMMG’s wholly-owned subsidiary Kaolin Resources.

The Gibson High Purity Alumina (HPA) project has a Joint Ore Reserves Committee (JORC) inferred resource of 147 million tonnes of aluminous clay at 10.3% alumina (Al2O3).

The 100%-owned project is located 10km by road from the Esperance port and comprises 200 blocks.

Previous exploration in 1990 by Western Mining Corporation, now BHP Billiton, included 47 aircore drill holes and a bulk testing programme.

AMMG managing director Ric Dawson said, "AMMG applied for the Gibson project based on the available historical data, which indicated grades of up to 21% alumina, with a screened grade of 37% alumina after the removal of the +2 micron size fraction.

"This attractive mineralogy is appropriate for our HPA processing technology,’ Dawson said.

AMMG owns the South West High Purity Alumina (HPA) project in Western Australia, where the company produced more than 99.9% high purity alumina (HPA) using its own aluminous clay (kaolin) to alumina processing technology.

South West HPA includes the three Meckering, Kerrigan, Bobalong and Kellerberrin project areas covering 2,934km².
