1. Australia's Identified Mineral Resources 2005

The latest edition of Australia's Identified Mineral Resources 2005 has been released by Geoscience Australia.

Australia's Identified Mineral Resources 2005 contains a wealth of minerals exploration and development information and is linked to the Australian Mines Atlas. The assessment includes evaluations of long-term trends in mineral resources, international rankings, summaries of significant exploration results, brief reviews of mining industry developments, and an analysis of mineral exploration expenditure across Australia. It shows that expansions in mine production of coking coal, iron ore, uranium and other commodities continued in 2004, and the resources sector overall continued to contribute to Australia's prosperity - economically, environmentally and socially. In 2004-05, over 35% of the country's total exports, with an estimated worth of $65 billion, came from the resources sector.

2. Seamless 1:1 million scale outcrop geology digital data for the whole of eastern Australia

Geoscience Australia will be releasing new seamless 1:1 million scale outcrop geology digital data for the whole of eastern Australia at the end of September. The data will be available in fully edgematched state portions - first edition data for Queensland and New South Wales, and second edition data for Victoria and Tasmania.

For further information, please email Ollie Raymond, or phone +61 (0)2 6249 9575.

3. New survey data added to the Australian National Gravity Database

New gravity data from a recent survey over the Birrindudu 1:250 000 Sheet Area have now been incorporated into the Australian National Gravity Database. Data were acquired at a station spacing of 2 km x 2 km. The survey project was managed by Geoscience Australia on behalf of the Northern Territory Geological Survey.

Data from two recent surveys over the Central Gawler Craton and the Central Curnamona Province by Primary Industry and Resources SA have been supplied to Geoscience Australia and added to the Australian National Gravity Database. The South Australian data cover parts of the following 1:250 000 sheet areas: Tarcoola, Childara, Streaky Bay, Yardea, Port Augusta and Gairdner for the Central Gawler Craton Survey and Callabonna, Frome and Curnamona for the Central Curnamona Province Survey.

All data in the Australian National Gravity Database can be obtained free-of-charge using the Geophysical Archive Data Delivery System (GADDS) download facility.

For further information, please email Mario Bacchin, or phone +61 (0)2 6249 9308.

4. Central Australian Basins Symposium

The Central Australian Basins Symposium (CABS) was held in Alice Springs from 16-18th August 2005, exploring the minerals and petroleum potential of Australia's Precambrian and Palaeozoic central basins. The three-day meeting included the release of results from the AMIRA P552: Fluid Flow Modelling in the Mount Isa and McArthur Basins, a collaborative project between Geoscience Australia, Geological Survey of Queensland, CSIRO, industry and academic institutions. Other Geoscience Australia presentations included new results from the Tanami and Paterson Projects.

More information on presentations at CABS can be found at CABS, or email Narelle Neumann, or phone +61 (0)2 6249 9429.

5. Broken Hill high resolution seismic survey

A high resolution seismic survey coincident along a portion of the 1996-97 AGSO deep seismic reflection line 9697AGS-BH1B was acquired in early August. A total of 12 km of high fold data was acquired across the Broken Hill Synform and Stephens Creek Shear Zone. Presentation of results from this survey is tentatively scheduled for the next BHEI Conference to be held in Broken Hill in September 2006. This is a collaborative project between Geoscience Australia and the New South Wales Department of Primary Industries - Mineral Resources (DPI-MR).

For further information, please email Bruce Goleby, or phone +61 (0)2 6249 9404.

6. Thomson-Lachlan Seismic Project

Australian National Seismic Imaging Resource (ANSIR), the National Research Facility of Earth Sounding, will complete the collection of deep seismic data in the Bourke-Wilcannia region of northwestern NSW on 4th September. Traverses are:

  • 05GA-TL1 - 99.20 km
  • 05GA-TL2 - 115.56 km
  • 05GA-TL3 - 87.12 km

This will provide 300 km of seismic data across Thompson-Lachlan Boundary and through the Nelyambo Trough and Mt Jack High structures. These data will help solve one of the key problems in the Tasmanides of eastern Australia, namely the location and nature of the east-west boundary between the Lachlan and Thomson orogens in northwest New South Wales. This is a collaborative project between the New South Wales Department of Primary Industries - Mineral Resources (DPI-MR), Geoscience Australia and the predictive mineral discovery Cooperative Research Centre (pmd*CRC).

For further information, please email Bruce Goleby, or phone +61 (0)2 6249 9404.

7. Thomson Orogen Project

Geoscience Australia, NSW Department of Primary Industries (DPI) and CRC LEME have developed a new collaborative project called the Thomson Orogen Project. The Thomson Orogen is the last orogen in NSW to be evaluated for mineral prospectivity and it is intended it will be the major target for a prospective third NSW DPI exploration initiative. The project's objective is the development of an effective means of exploring through what is believed to be mostly shallow cover. In the first year the project will focus on regional geochemical and biogeochemical surveys.
