Goulburn-Taralga Bauxite Resource up by 50% - 38 Million Ton
ABx and Marubeni Corporation are conducting a AU$1.5 million pre feasibility study of the Goulburn Bauxite Project. This zone of thick bauxite increases the resource potential of the Taralga bauxite areas, near Goulburn NSW.
The district's deposits contain thick zones of premium grade bauxite, with good potential for more discoveries. All deposits are gibbsite-rich (trihydrate) bauxite, low in reactive silica and free of refractory mineral boehmite (monohydrate).
All horizons produce Direct Shipping or "DSO" bauxite.
Resource Estimation and Deposit Geometry
Areas of thick, good quality bauxite continue to be discovered across the Taralga - Mt Rae Areas and new bauxite target areas have been identified in new tenements that have been recently granted. Over the last 12 months, bauxite resources at Taralga have increased by 50% from 25 million tonnes to the current estimate of 37.9 million tonnes.
Metallurgical Results Encouraging: Main Production is DSO Bauxite Metallurgical tests on large samples have been conducted as part of the Pre Feasibility Study, with METS Engineers of Perth coordinating and summarising the testwork.
The Goulburn Bauxite Project deposits typically have an upper half that contains nodules or "pisoliths" of a black, glassy material which is an emery, comprising mainly fused alumina and trace iron oxides. Well-known bauxite mineralogist, Professor Eggleton of the Australian National University coined the term "PDM" for these black pisoliths which he found in bauxites from Weipa, Northern QLD. PDM stands for "poorly diffracting material" when subjected to X-ray diffraction.
Metallurgical tests on the PDM-bearing bauxite ("PDM-DSO Bx") from the Taralga area have been able to recover the PDM by gravity methods and the remaining bauxite is good-quality DSO bauxite, similar to the DSO bauxite that typically occurs in the lower half of the deposits. This means that overall, DSO Bauxite will represent approximately 80% to 85% of total tonnes produced from the Goulburn Bauxite Project. The recovered PDM emery material can be sold at good prices for industrial uses.

About Australian Bauxite Ltd
Australian Bauxite Limited (ABx) (ASX:ABX) has started its first bauxite mine in Tasmania and holds the core of the Eastern Australian Bauxite Province. ABx's 37 bauxite tenements in Queensland, New South Wales and Tasmania exceed 5,000 km2 and were rigorously selected for (1) good quality bauxite; (2) near infrastructure connected to export ports; and (3) free of socio-environmental constraints. All tenements are 100% owned, unencumbered & free of third-party royalties.
ABx's discovery rate is increasing as knowledge, technology and expertise grows.
The Company's bauxite is high quality gibbsite trihydrate (THA) bauxite and can be processed into alumina at low temperature.
ABx has declared large Mineral Resources at Inverell and Guyra in northern NSW, Taralga in southern NSW, Binjour in central QLD and in Tasmania confirming that ABx has discovered significant bauxite deposits including some of outstandingly high quality.
In Tasmania, at Bald Hill, the Company's first bauxite mine commenced operations on schedule on 9 December 2014 – the first new Australian bauxite mine for more than 35 years.
ABx aspires to identify large bauxite resources in the Eastern Australian Bauxite Province, which is emerging as a globally significant bauxite province. ABx has created significant bauxite developments in 3 states - Queensland, New South Wales and Tasmania. Its bauxite deposits are favourably located for direct shipping of bauxite to both local and export customers.
ABx endorses best practices on agricultural land, strives to leave land and environment better than we find it. We only operate where welcomed.
