New seismic data releases from South Australia and Queensland

Arrowie Seismic Survey (08GA-A01)

Un-interpreted processed data from the Arrowie Seismic Survey will be available from 1 May 2009. Geoscience Australia undertook acquisition of deep seismic reflection in South Australia as part of the Onshore Energy Security Program in June - July 2008. The survey consisted of three traverse lines, one across the Gawler Craton (08GA-G01, 253 km), one across the Curnamona Province (08GA-C01, 262 km) and one in the Arrowie Basin (08GA-A01, 60.4 km). Geoscience Australia is currently processing the Gawler and Curnamona lines, and it is planned to release the processed data in September 2009. Unprocessed data for all of these lines are already available.

Mt Isa-Georgetown-Charters Towers Survey (07GA-IG1, 07GA-IG2 and 07GA-GC1)

A total of 1387 km of 2D seismic reflection data collected over four lines in Northern Queensland will be released on 3 June 2009 at a workshop being held in conjunction with the Australian Institute of Geoscientists (AIG) Northern Queensland Exploration and Mining Conference in Townsville. The interpreted processed seismic data and the magnetotelluric data will also be released at this time. The Mt Isa – Georgetown – Charters Towers seismic survey from May to October 2007, acquired deep seismic reflection, gravity and magnetotelluric data along three traverses, 07GA-IG1, 07GA-IG2 and 07GA-GC1. Funding for this survey was obtained through Geoscience Australia's Onshore Energy Program and Queensland's Smart Mining – Future Prosperity Program. The aims of the survey were to image the crust from the eastern edge of the Mt Isa Province, across the Georgetown Region, and southeast through the Charters Towers area and into the Drummond Basin.

A fourth traverse (07GA-A1) was funded by AuScope, an initiative established under the National Collaborative Research Infrastructure Strategy to characterise the structure and evolution of the Australian continent. This line imaged from Mareeba to Mt Surprise across the Palmerville Fault (Tasman Line).

2.New seismic data from Northern Territory

Georgina Basin - Arunta Inlier Survey (09GA-GA1)

Geoscience Australia, as part of the Onshore Energy Security Program and in collaboration with the Northern Territory Geological Survey, is undertaking a deep seismic survey across the Georgina Basin and the Arunta Inlier, and into the Amadeus Basin. The survey is scheduled to start in late May and comprises a single 376 km traverse, commencing just north of the Sandover Highway and concluding near Todd River Downs. The aims of this traverse are to enhance the knowledge of the petroleum prospectivity of the Georgina and Amadeus basins, and to investigate the uranium potential of the Arunta Inlier

3. North Queensland Seismic and Magnetotelluric Workshop, Townsville, 3 June 2009

(Held in conjunction with the AIG North Queensland Exploration and Mining conference 4-5 June 2009)

The results of four deep seismic survey and magnetotelluric (MT) traverses, extending from the eastern margin of the Mt Isa Inlier, across Mesozoic cover of the Carpentaria Basin into the Georgetown Block and then into Paleozoic rocks of the Tasman Orogen, will be presented to the public in Townsville on 3 June 2009, in conjunction with the North Queensland Exploration and Mining Conference (4-5 June). The results are based on seismic data acquired in 2007 and collectively funded by Geoscience Australia, the Geological Survey of Queensland and AuScope. These lines provide architectural information on the Croydon, Georgetown, Hodgkinson, Balcooma, Charters Towers, Seventy Mile Range and Pajingo mineral fields. The workshop will present the results of geochronological, geochemical and isotopic studies designed to support the seismic interpretations.

For further information on the workshop, email russell.korsch@ga.gov.au; or phone +61 2 6249 9495; david.huston@ga.gov.au; or phone +61 2 6249 9577.

Further information on the North Queensland Exploration and Mining conference can be obtained from, email lantana@beyond.net.au; or phone +61 7 4772 5296.

4. Broken Hill Exploration Initiative Conference

A conference will be held in Broken Hill from 29 September-1 October 2009 to report on new insights into exploration geoscience in the Curnamona Craton and adjacent areas. This is being organised jointly by the NSW Department of Primary Industries, Primary Industries and Resources South Australia and Geoscience Australia.

Further information on this conference can be found on the NSW Department of Primary Industries website; or email russell.korsch@ga.gov.au; or phone +61 2 6249 9495.

5. New airborne magnetic and radiometric surveys for Western Australia

Requests for quotation closed on Thursday 30 April 2009 for provision of new airborne magnetic and radiometric data over Western Australia funded by the Western Australia Government's Department of Mines and Petroleum Exploration Incentive Scheme (EIS). The EIS will complete the coverage of Western Australia by medium resolution airborne magnetic and radiometric surveys over the next five years. This first Quotation Request refers to eight survey areas in the Kimberley, Canning, Pilbara, Carnarvon and Eucla areas of Western Australia comprising a total of just under 2.5 million line kilometres of new data.

For further information, email murray.richardson@ga.gov.au; or phone +61 2 6249 9229.

6. 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.

Requests for quotations for the South Yilgarn, Western Australia and Barkly region, Northern Territory gravity surveys close on 12 May 2009.
