1. Airborne electromagnetic data for South Paterson released

Airborne Electromagnetic (AEM) data for the South Paterson survey, Western Australia were released on 4 March 2009. These data were collected with line spacing of one and two kilometres and cover the Rudall Complex and Coolbro Sandstone of the Paterson Province and Neoproterozoic to Mesozoic sediments of the Officer and Canning Basins. The survey results will provide information on the conductivities of a variety of surface and near surface materials which will aid exploration in the appropriate application of AEM in the region.

The data are available on DVD from the Geoscience Australia Sales Centre or telephone 1800 800 173.

2. New Southern Gunnedah gravity survey data now open file

On 23 February 2009, the 2008 Southern Gunnedah gravity survey became open file and available for download from the Australian National Gravity Database.

This survey covering parts of the Gilgrandra, Tamworth, Dubbo and Singleton 1:250 000 sheet areas was comissioned by the Geological Survey of New South Wales and subsequently included in the Australian National Gravity Database.

Station spacing for the survey is two kilometres and the total number of new gravity stations from the survey is 5406.

Open file data in the Australian National Gravity Database can be obtained free-of-charge via the Geophysical Archive Data Delivery System (GADDS).

3. Australian mineral exploration peaks

Although Australian and global mineral exploration reached record highs during 2008, the end of the commodities boom as a consequence of the global economic downturn is likely to see a sharp drop in exploration expenditure in the immediate future.
