Gibbsitic bauxite at South Johnstone confirmed by XRD Laboratory Results Suitability of bauxite for low temperature processing confirmed Gibbsite shown to be main mineral phase present in South Johnstone bauxite s (36-48%) Queensland Bauxite Limited (ASX:QBL) is pleased to announce that X-ray Diffraction (XRD) results have been received for selected drill samples from our South Johnstone Bauxite Project in Queensland. This work provides further insight into the nature of the South Johnstone bauxite. The XRD work confirms gibbsite to be the dominant mineral phase present. This is the preferred form of bauxite as it is easier to process than non-gibbsitic bauxite. The negligible amount of boehmite (0-2%) and diaspore (0-3%) further confirms the suitability and preference of low temperature processing. Details of QBL’s 30 million tonne Inferred Resource at South Johnstone referred to in the announcement released to the market on 3 July entitled ‘Update on South Johnstone Bauxite Project’ were reported in QBL’s announcement addendum of 17 June 2014 with the following parameters
