Bauxite exploration and development company Australian Bauxite Limited has received laboratory results from the last 14 holes drilled at its Binjour project between Gayndah and Mundubbera, south of Gladstone in central Queensland.
Of the 14 holes drilled in the last phase of drilling in 2010, 11 holes intersected a thick layer of bauxite. Results from these 11 holes include exceptionally high grade, suggesting relatively pure gibbsite bauxite, ideal as a 'sweetener' to any bauxite refinery.
Australian Bauxite's CEO Ian Levy says, “Binjour may prove to be a very high quality bauxite deposit, shippable in large tonnages to a number of bauxite-alumina refineries that need 'sweetener-grade' bauxite that can be processed at low temperature and with exceptionally low reactive silica contents.
"We've called this bauxite type 'Brown Sugar' bauxite - which may become a brand name in the industry one day. Some customers may become dependent on this product and pay quite handsomely for it.”
At the Taralga project 40km north of Goulburn in southern NSW bauxite resources totalling 12 million tonnes were identified from first-pass drilling in 2010. More than half of the resources are easily mined direct shipping ore (DSO) grade bauxite suitable for direct shipping to customers that require gibbsite-rich bauxite, which is the premium quality bauxite that is in highest demand globally.
The bulk of these initial resources came from Areas B & C but a new bauxite deposit has been discovered in the southeast of the tenement at Area A and this is now being drilled as a matter of priority.
During the January drilling cycle, a total of 225 holes were drilled in Area A and some zones of exceptionally thick bauxite layers were discovered, including one hole that intersected bauxite from surface to 18 metres depth. The new deposit in Area A appears significantly larger than the deposits in Areas B and C, both in thickness and areal extent.
Drilling in Tasmania was done on grazing and cropping farmland around Campbell Town in the Tasmanian midlands. Bauxite has been encountered in drill holes and in surface sampling.
Initial results have been compiled for Deloraine. Results to date are from the edges of the deposit and from some outlier occurrences of bauxite and they demonstrate that DSO grades occur in reasonable thicknesses.
Australian Bauxite holds the core of the Eastern Australian Bauxite Province with 29 tenements in Queensland, NSW, Victoria and Tasmania covering more than 7000sqkm.
At the company’s first drilling prospect in Inverell, northern NSW, a maiden resource of 22 million tonnes has been reported from drilling less than 10% of the identified bauxite deposit.
