Minerals Alert February 2011

A monthly online newsletter with product news, data releases and projects relating to the minerals and energy exploration industry.

1. Workshop on new seismic and MT datasets in Victoria and South Australia

There will be a half day (morning) workshop on Friday 4 March 2011 in Melbourne to present the results of new seismic reflection and magnetotelluric data collected for the 2009 Southern Delamerian (L193) and Ararat (L194) seismic surveys across the Glenelg and Grampians-Stavely Zones of the Delamerian Orogen and the Stawell Zone of the western Lachlan Orogen. The workshop will be held in conjunction with GeoScience Victoria, AuScope and the Department of Primary Industries and Resources South Australia (PIRSA).

The processed seismic data is now available and can be downloaded from the Geoscience Australia website.

To obtain details on the workshop and to register, please email leonie.jones@ga.gov.au; or phone +61 2 6249 9540.

2. Workshop on new seismic and MT datasets in southern Northern Territory

There will be a half day (afternoon) workshop on Wednesday 23 March 2011 in Alice Springs to present the results of new seismic reflection and magnetotelluric data collected for the 2009 Georgina-Arunta (L192) seismic survey across the Georgina Basin, Aileron and Irindina provinces of the Arunta Region and the northeastern Amadeus Basin. The survey and workshop are in conjunction with the Northern Territory Geological Survey, and will form part of the Annual Geoscience Exploration Seminar (AGES).

The processed seismic data is now available and can be downloaded from the Geoscience Australia website.

To obtain details on the workshop, please email russell.korsch@ga.gov.au; or phone +61 2 6249 9495.

Registrations are through the AGES website.

3. Kombolgie airborne electromagnetic survey images to 2km depth

Three regional Airborne Electromagnetic (AEM) surveys have been acquired by Geoscience Australia under the Australian Government's Onshore Energy Security Program. They are the Paterson (Western Australia), Pine Creek (Northern Territory) and Frome (South Australia) regions which are considered to have potential for uranium or thorium mineralisation. The Pine Creek airborne electromagnetic survey in the Northern Territory included a large area of VTEMTM data collected over the Kombolgie area, which contains the Nabarlek uranium deposit. Reprocessing of the Kombolgie AEM data has produced an enhanced set of conductivity estimates which image features such as unconformities and major structures to depths of up to 2km. This is a major improvement on typical airborne electromagnetic system penetration of up to 800m.

The new conductivity sections are now available from the Geoscience Australia website.

For further information, please email nick.williams@ga.gov.au; or phone +61 2 6249 5807.

4. Additional airborne electromagnetic data and conductivity logging data releases

To support the interpretation of the three regional Airborne Electromagnetic (AEM) datasets acquired by Geoscience Australia under the Australian Government's Onshore Energy Security Program, Geoscience Australia also collected down-hole conductivity logs for a number of drillholes in each area. Data from these logs is available free of charge from the Geoscience Australia website for the survey areas at Pine Creek in the Northern Territory and Paterson in Western Australia.

Two areas of previously confidential infill AEM data and inversion products in the Pine Creek area also have been released from the Rum Jungle TEMPESTTM survey along with three areas of previously confidential infill AEM data from the Pine Creek Kombolgie VTEMTM survey.

For further information, please email nick.williams@ga.gov.au; or phone +61 2 6249 5807.

5. Update on geophysical data releases

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