Goulburn-Taralga Bauxite Resource up by 50% - 38 Million Ton
Goulburn-Taralga Bauxite Resource up by 50% - 38 Million Ton
Sydney, May 31, 2012 AEST (ABN Newswire) - Emerging bauxite exploration and development company, Australian Bauxite Limited (ASX:ABZ) has 40 bauxite tenements totalling more than 8,700 km2 covering the core of the Eastern Australian Bauxite Province. As announced on 30 May 2012, a discovery of extraordinarily thick bauxite at Mt Rae near Taralga, 40km north of Goulburn southern NSW in February-March 2012 has led to an expansion of the Pre Feasibility Study (PFS) for the Goulburn Bauxite Project and a resource upgrade has now also been undertaken as part of that expanded PFS.

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.

Australian Bauxite Ltd ASX:ABXAustralian Bauxite Limited (ABx) (ASX:ABX) has its first bauxite mine in Tasmania and holds the core of the Eastern Australian Bauxite Province. ABx's 22 bauxite tenements in Queensland, New South Wales & Tasmania exceed 1,975 km2 and were selected for (1) good quality bauxite; (2) near infrastructure connected to export ports; & (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 & expertise grows.

The Company's bauxite is high quality gibbsite trihydrate (THA) bauxite that can be processed into alumina at low temperature.

ABx has declared large Mineral Resources at Inverell & Guyra in northern NSW, Taralga in southern NSW, Binjour in central QLD & in Tasmania, confirming that ABx has discovered significant bauxite deposits including some of outstandingly high quality.

At Bald Hill near Campbell Town, Tasmania, the Company's first bauxite mine commenced operations in December 2014 – the first new Australian bauxite mine for more than 35 years. 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.
