The company’s bauxite is high quality and can be processed into alumina at low temperature – the type that is in short supply globally. At the company’s first drilling prospect in Inverell, northern NSW, an interim resource of 35 million tonnes[1] has been reported from drilling 15% to 20% of the area prospective for bauxite and a resource of 25 million tonnes[2] of bauxite has been reported at the Taralga project in southern NSW. Results from the Binjour Plateau in central QLD confirm that ABx has discovered a significant bauxite deposit including some bauxite of outstandingly high quality. Australian Bauxite Limited aspires to identify large bauxite resources in the Eastern Australian Bauxite Province which is emerging as one of the world’s best bauxite provinces.
TARALGA, NSW
Taralga bauxite resource doubled to 25 million tonnes
-
Pre-feasibility baseline studies initiated for Goulburn Bauxite Project
-
25.3 million tonnes of gibbsite-rich bauxite resources at Taralga, southern NSW
-

EXPLORATION
Exploration during the June quarter was focused on identifying extensions to identified targets and declared resources.
The Goulburn cluster of tenements was upgraded to "project" status and a prefeasibility baseline study has commenced. First pass drilling was undertaken at Guyra, NSW (EL 7361), with exceptional results.
TARALGA, NSW (EL 7357 and EL 7681)
To clarify the marketability of the bauxite types found in the Taralga-Goulburn-Crookwell area in southern NSW, detailed drilling was conducted at spacings of approximately 100 metres in areas containing easily mined bauxite zones of Direct Shipping Ore (DSO) grades because Taralga is located near a major railway line leading directly to Port Kembla export terminal (see Figures 2 & 3).
Two main bauxite types are recognised at Taralga as shown in Figure 1, namely:
-
Gibbsite rich, low silica bauxite that will be the main component of direct shipping ore (DSO);
-
Pisolitic, dehydrated hardcap bauxite, often forming a surface hardcap layer 2 metres thick .
Each bauxite type can have quartz-rich zones where quartz grains have mixed with the bauxite.
Figure 1: Taralga Bauxite Types
Bauxite types at Taralga – schematic section.
Main bauxite is gibbsite-rich, low silica bauxite.
Surface layer is commonly a 2 metre layer of pisolitic, iron rich bauxite that can be cemented into a hardcap layer.
Each bauxite type can have quartz-rich zones where quartz grains have mixed with the bauxite.
==> picture [191 x 239] intentionally omitted <==
Resources at Taralga based on drilling to date can be summarised as follows:
- 10 Million Tonnes of DSO Bauxite
==> picture [453 x 113] intentionally omitted <==
This DSO gibbsite ore is considered to be the main type of bauxite in the Goulburn-Taralga-Crookwell district.
Quarterly Activities Report – June 2011 Page 4
==> picture [87 x 62] intentionally omitted <==
2. 10 million Tonnes of Pisolite Ore
In many locations, there is a 2 metre thick surface layer of “Pisolite Ore” above the main gibbsite bauxite. This is pisolitic (rounded gravels), iron-enriched, dehydrated bauxite which is cemented into a hardcap layer in places.
==> picture [453 x 114] intentionally omitted <==
Note that this material has elevated levels of iron (Fe2O3) and low loss-on-ignition (LOI) which indicates dehydration. Note also that 15% of the alumina (Al2O3) does not report as available Al2O3 at the leach temperatures used here. At moderately higher leach temperatures, it is expected that more of the total alumina would report as being available Al2O3. This will be tested as part of metallurgical testwork scheduled for June-July.
3. 5 million Tonnes of Quartz-Bearing Bauxite
At depth and laterally, both major bauxite types can become quartz-bearing bauxite in the form of sand grains and small layers of quartz-rich gravels mixed with bauxite. In places, this material is peripheral to the main deposits.
The major bauxite deposits in the Darling Ranges bauxite-alumina projects south of Perth, Western Australia are quartzbearing and there are many similarities between the bauxites of the Eastern Australian Bauxite Province and the WA Darling Ranges bauxites.
Quartz is an inert, non-reactive form of silica (SiO2) which does not affect the processing of the bauxite into alumina and aluminium. However, it does dilute the grades of the bauxite as shown by the following tables.
==> picture [453 x 197] intentionally omitted <==
Note that total silica (SiO2) is approximately 20% in these bauxites, but only 1.9% to 3.1% is reactive silica (Rx SiO2 in the above tables).

RESOURCE ESTIMATE METHOD
Drilling on a random pattern governed by site availability was done predominantly in the northeastern parts of EL 7357 (Areas B & C in Figures 2 & 3) where bauxite plateaus were obvious and some in the southwestern parts of EL 7357 where unexpectedly thick, good quality bauxite was discovered (Area A in Figure 2) in late 2010.
During August 2010, 98 holes were drilled totalling 710 metres and during September-October 2010, a further 112 holes were drilled totalling 985 metres. Infill drilling done during the first Quarter of 2011 brought the total drilling at Taralga to 577 drillholes totalling 4,575 metres drilled.
Drill samples were collected at 1 metre intervals from the aircore drillholes and analysed at ALS Laboratories in Brisbane including trihydrate (THA) available alumina (Avl Al2O3) and reactive silica (SiO2 Rx) measurements. Leach conditions to measure available Avl Al2O3 and reactive SiO2 Rx were 1g leached in 10ml of 90gpl NaOH at 143 degrees C for 30 minutes
Estimation of grades and thicknesses was done by an inverse distance squared modelling method using maximum extrapolations of 100 metres for Indicated Resources category and 150 metres for Inferred Resources. Bauxite density was conservatively assumed at 1.8 dry tonnes per cubic metre in-situ.

Taralga Tenements, Bauxite Areas, Drillhole Locations & Infrastructure
Drilling commenced in Areas B & C because of obvious bauxite plateaus.
Unexpectedly good bauxite (some with non-reactive quartz) was discovered in Area A in late 2010.
Western area EL 7681 covers possible extensions.
The Taralga and Crookwell rail lines are disused.
Goulburn-Port Kembla rail is heavy duty
GUYRA, NSW (EL 7361)
During the June quarter drilling commenced at EL 7361.
63 holes intersected a thick layer of bauxite located beneath a thin clay horizon, including some exceptionally high grade, thick gibbsite bauxite, ideal as a “sweetener” to any bauxite refinery.

Logistical Setting
The best part of the bauxite discovered to date at Guyra is it is immediately adjacent the standard gauge rail line connecting Guyra to Armidale, Werris Creek and thence to the heavy-duty rail to Newcastle minerals export port. Operations of the Guyra-Armidale rail has recently been suspended but the rail line is still in good condition, having recently been used for transportation of logging products.
Wingello, NSW (EL 7279)
Drilling commenced at Wingello (NSW) with 33 holes for 243 meters. Drilling located up to 5 metres of bauxite. Further exploration will focus on ground traversing in preparation for a further drilling program.

QUALIFYING STATEMENTS
The information in this report that relate to exploration programmes are based on information compiled by Jacob Rebek who is a member of Australian Institute of Mining and Metallurgy. Mr. Rebek is a qualified geologist and is a director of Australian Bauxite Limited.
Mr. Rebek has sufficient experience, which is relevant to the style of mineralization and type of deposit under consideration and to the activity, which he is undertaking to qualify as a Competent Person as defined in the 2004 Edition of the Australasian Code for Reporting of exploration Results, Mineral Resources and Ore Resources. Mr. Rebek consents to the inclusion in the report of the matters based on information in the form and context in which it appears.
Exploration Target Statement
ABx has an exploration target of 200 to 300 million tonnes of bauxite (40-50 million tonnes is the exploration target for the Goulburn Bauxite Project area), based on the Mineral Resources totalling 36 million tonnes of bauxite from 196 drillholes drilled across an area that is less than 15% of the known bauxite deposits on a single Exploration Lease EL 6997 at Inverell in northern NSW. Furthermore, Mineral Resources totalling 25 million tonnes of bauxite have been estimated from 577 drillholes that have tested approximately 60% of the known bauxite deposits at Taralga on EL 7357.
In accordance with the JORC Code, readers are advised that with regards this exploration target of 200 to 300 million tonnes, “the potential quality and grade is conceptual in nature, that there has been insufficient exploration to define full Mineral Resources and that it is uncertain if further exploration will result in the determination of a Mineral Resource”. Inverell tenement EL 6997 was the first of 30 tenements to be drilled and has since discovered sizeable, good quality bauxite occurrences on several other tenements.
Direct Shipping Ore
In this report all references to direct shipping ore (DSO) refers to the company’s exploration objective of defining DSO grade mineralisation.
