1. Australia's Identified Mineral Resources 2008 (AIMR) - online release

The latest edition of Australia's Identified Mineral Resources (AIMR 2008) is now available online.

The AIMR report is compiled annually by Geoscience Australia to provide governments, the resource industry, the investment sector and the general community with an informed understanding of Australia's known mineral resources and the level of Australia's exploration activity.  One of the report's most important objectives is to monitor whether resources are being discovered and developed for production at rates sufficient to maintain Australia's position as a major supplier of mineral commodities.

2. New gravity survey data added to the Australian National Gravity Database

Geoscience Australia now has available 8347 open-file company gravity stations from Western Australia and 7667 open-file company gravity stations from the Northern Territory, which were added recently to the Australian National Gravity Database. Data from the surveys are situated on the 1:1 Million sheets areas for Alice Springs, Darwin, Hall Creek, Lake Mackay, Newcastle Waters, Roper River in the Northern Territory and Esperance, Hamersley Range, Kalgoorlie, Meekatharra, Perth and Wiluna in Western Australia.

These data have been supplied to Geoscience Australia by the respective State or Territory Geological Survey. All data in the National Gravity Database can be obtained free-of-charge using the Geophysical Archive Data Delivery Systems GADDS.

3. New seismic survey - Gawler-Officer-Musgrave-Amadeus Seismic Survey

Geoscience Australia currently is conducting a seismic survey in northern South Australia and southern Northern Territory. The aim of this survey is to provide new insights into the crustal architecture of two Neoproterozoic sedimentary basins in Central Australia and their tectonic relationships to older, Mesoproterozoic basement terrains. The survey also may identify structural elements in the basinal sections which could host hydrocarbons generated prior to the Alice Springs Orogeny.

The survey consists of one continuous north-south traverse beginning 350 km northwest of Port Augusta. The line crosses from the Gawler Province, over the Officer Basin to the Musgrave Block and then into the Amadeus Basin in the Northern Territory. This traverse is planned to be approximately 634 km long and is jointly funded by Geoscience Australia through the Onshore Energy Security Program, AuScope (initiative to characterise the structure and evolution of the Australian continent) and Primary Industries and Resources SA.

Data acquisition commenced at the northern end of the traverse approximately 25 km southeast of Erldunda in the Northern Territory on 1 November 2008. This traverse follows the Adelaide to Alice Springs railway line utilising the railway access road and is planned to conclude in late December 2008 near Tarcoola in South Australia.

4. Update on geophysical data releases

The current status of Geoscience Australia's geophysical survey data acquisition is available in a comprehensive table from the Geoscience Australia website.

Data were released for the Byro airborne magnetic and radiometric survey on 2 October 2008.
