1. Workshops on Geoscience Australia's Northern Territory Pine Creek AEM Survey Data

The first workshop was presented in Alice Springs immediately following the recent AGES conference. There will be a repeat half-day (morning) in Perth at 9:00am on Tuesday 7 June, 2011, at The Celtic Club Inc., 48 Ord Street West Perth.

Registration forms containing details of the workshop in Perth can be downloaded from the Airborne Electromagnetics Project.

The processed AEM data for this survey is available as a free download.

To obtain further details on the workshop, please email mike.craig@ga.gov.au; or phone +61 2 6249 9453.

2. The Frome Phase 1 AEM data are available

Geoscience Australia announces the release of the Phase 1 (contractor-delivered) data from the Frome airborne electromagnetic (AEM) survey, South Australia. The Frome AEM survey covers 95 450km2 and includes 32 300 line kilometres of data flown using the Fugro Airborne Services TEMPESTTM system at 2.5km and 5km flight line spacing and 100m average height above ground. The survey primarily targeted potential uranium-bearing mineral systems in the Callabonna Sub-basin of the Frome Embayment and the Lake Eyre Basin on the flanks of the northern Flinders Ranges, continuing to Marree and Cameron Corner, and also includes the northwest Murray Basin. Phase 2 data, to be released later in 2011, will include new inversions using the Geoscience Australia layered earth inversion (GA-LEI) algorithm to produce point-located ASCII data and geo-located grids and sections to further promote the prospectivity of the Frome region.

The Phase 1 data are now available as a free download or as a $99 DVD-ROM from the Sales Centre.

For more information please email david.hutchinson@ga.gov.au or phone +61 2 6249 9802; or ian.roach@ga.gov.au or phone +61 2 6249 9683.

3. New maps and report released on magmatic-related uranium systems potential

As part of the Onshore Energy Security Program, Geoscience Australia has released two new national-scale maps of the potential for magmatic-related uranium mineral systems. The first map, Potential for magmatic uranium systems in Australia Map 1: Intrusive-related, shows the potential for uranium systems associated with intrusive igneous rocks across the continent. The second map, Potential for magmatic uranium systems in Australia Map 2: Volcanic-related, targets uranium systems genetically linked to volcanic rocks. Both maps utilise national data coverages, including whole rock geochemistry, as well as Geoscience Australia's 1:1 million Surface Geology of Australia and radiometric datasets.

The maps are accompanied by Geoscience Australia Record Potential for magmatic-related uranium mineral systems in Australia, which describes the methodology and results of the study. Together, the maps and report aim to identify igneous events and units which exhibit favourability for magmatic-related uranium mineral systems.

4. Update on geophysical data releases

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