1. Science at the Surveys Seminar 22 March 2010

Geoscience Australia and the State Geological Surveys are presenting a one day seminar in Melbourne on Monday 22 March 2010, titled Science at the Surveys. The program will consider the exploration opportunities identified by and arising from the results of pre-competitive geoscience programs undertaken by these agencies. Topics include 3D regional geological models and maps, 3D mapping of mineral systems, iron-oxide copper-gold-uranium systems, uranium systems and gold mineral systems.

Attendance is free, but registration in advance is required. To register and obtain the full program details see the Science at the Surveys flyer [PDF 1.3MB].

For more information, email susan.wall@ga.gov.au; or phone +61 2 6249 9828.

2. Workshop on new South Australian seismic and MT datasets

There will be a one-day workshop on Thursday 6 May 2010 in Adelaide to present the results of new seismic reflection and refraction and magnetotelluric data collected during 2008 and 2009 in South Australia in conjunction with the Department of Primary Industries and Resources, South Australia. The seismic lines presented include the Curnamona, Gawler-Curnamona link, Arrowie and Eyre Peninsula transects.

This workshop will follow the South Australian Resources and Energy Investment Conference (SAREIC) on 3-4 May 2010 and the Technical Forum on 5 May 2010.

To obtain more details on the workshop and register see the South Australian Seismic and MT workshop flyer [PDF 533KB].

3. Australian Mineral Exploration Review for 2009

Geoscience Australia has released Australian Mineral Exploration, a review of mineral exploration in Australia which examines levels and trends in exploration for the year 2009. The review also highlights government initiatives to support exploration. Overall expenditure in 2008-09 fell by 9.7 per cent to $2223.1 million. This is in contrast to the 42 per cent fall recorded for non-ferrous mineral exploration budgets by the Metals Economics Group. Australian falls were cushioned by the continuing strong demand for iron ore and coal exploration. Drilling undertaken in the search for previously unknown mineralisation fell by 31 per cent to 2.72km in 2008-09, reflecting the continuing strong preference for brownfields exploration. Exploration results were announced for a wide range of commodities from across the country including:

  • initial resource estimate for the Merlin molybdenum-rhenium deposit in Queensland
  • significant drill intersections at the DeGrussa and Bentley base metals prospects in Western Australia
  • significant drill intersections at the Thunderball uranium prospect in the Northern Territory
  • the first commercial grade gold intersections from the West Musgrave region in Western Australia.

A concise edition of Australian Mineral Exploration is also is available.

4. Geoscience Australia Record on Central Australian Energy prospectivity released

As part of its Onshore Energy Security Program, Geoscience Australia has released GA Record 2009/025, Hydrocarbon and Geothermal Prospectivity of the Sedimentary Basins in Central Australia: Warburton, Cooper, Perdirka, Galilee, Simpson and Eromanga Basins.

This document covers the region which is Australia's most productive onshore petroleum province. The document also features world class geothermal resources contained in underlying high heat producing granites.

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

On 20 January 2010, the confidential data collected along the 2009 Curnamona-Gawler seismic link line became open file. These 360 stations were collected at 400m spacing in conjunction with the seismic survey conducted by Geoscience Australia and the South Australian Department of Primary Industries and Resources along the 2009 Curnamona traverse crossing from the Gawler Craton to the Curnamona Province. The Curnamona-Gawler link line is located in South Australia on the Tarcoola and Broken Hill 1:1 Million sheet areas.

The Geological Survey of New South Wales has supplied point located and gridded data from its 2009 Broken Hill-Western New South Wales Gravity Survey. Observations were made at 2km x 4km with some infill at 2km x 2km. The survey extended from 31°S to the New South Wales/Victorian border and from the New South Wales/South Australian border to 142°E. The total number of new stations is 6999. A revised gravity grid of New South Wales incorporating this new Broken Hill survey has been produced by the Geological Survey of New South Wales at a cell size of 500m. The grid and point located data are available to download through the Geophysical Archive Data Delivery System (GADDS).

Data from six Western Australian open file company surveys made available to Geoscience Australia by the Geological Survey of Western Australia have been entered into the Australian National Gravity Database (ANGD). Surveys are located on the Kalgoorlie, Esperance, Wiluna and Broome 1:1 Million sheet areas. The total number of new stations is 4325.

Data from two Tasmanian open file company surveys have been added to the ANGD. The Mount Painter Survey has 1823 stations at station spacings of 100 to 500m. The Central Tasmania Survey has 1888 stations read along traverses with average station spacings of 500m. All data are located on the Tasmania 1:1 Million sheet area and were supplied by Mineral Resources Tasmania. Updated data for approximately 2000 stations have been received from Mineral Resources Tasmania. Most of these stations are from 1973 gravity surveys. These updated stations have been added to the ANGD to replace the previous data.

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

6. Drilling database for the Paterson region, Western Australia

The Geoscience Australia Record, A drill hole database for the Paterson airborne electromagnetic (AEM) survey, Western Australia, describes a new database containing historical drill hole locations and geology logs for the Paterson region of Western Australia. The database was prepared to support the regional, 29 000 line kilometre TEMPEST airborne electromagnetic (AEM) survey acquired over the area as part of the Onshore Energy Security Program in 2007-08 and publicly released in 2009. More than 6500 drill hole locations, with 4300 associated down hole geological logs, are supplied in accompanying text CSV files suitable for import into GIS, drill hole management or mine planning software.

7. Update on date on geophysical data releases

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

The South Yilgarn gravity survey was released via the Geophysical Archive Data Delivery System (GADDS) on 25 February 2010.
