1. It's a new look for our minerals pages

We have redesigned the Minerals Division section of our web site. Now with improved navigation, updated project pages, new resources, and new publications, this section of Geoscience Australia's website contains a complete list of all Minerals Division projects, publications, databases, 3D models and online applications.

Further improvements have been made across the agency's web site. A new search engine is being trialled, which you can test by going to the Geoscience Australia home page and entering a term in the search box. In addition, a survey is now underway to gather client feedback on the agency's web site. You can access the survey by clicking the "Rate this page" drop down menu at the bottom of every web page, or by visiting the online survey page.

For more information or to send feedback on the new look Minerals Division web pages, please email Minerals web staff.

2. 1:1 million geology datasets for the whole of eastern Australia

Geoscience Australia has released the 1st edition 1:1 million geology datasets for NSW, Queensland, and 2nd edition 1:1 million geology datasets for Tasmania, and Victoria. The datasets can be downloaded free or ordered on CD in ESRI coverage and shapefile formats from the GA Sales Centre.

For further information, please email Ollie Raymond; or phone +61 (0)2 6249 9575.

3. Evolution and metallogenesis of the North Australia Craton

The North Australia-Tanami Project will hold an end-of-project meeting in Alice Springs on 20-22 June next year. This meeting, which will also involve contributions from state and industry partners, will present a summary of results from the North Australia and Tanami Projects which have run since July 2000. Highlights of the meeting include:

  • a summary of event chronologies and their relationship to mineral systems in the Tanami, Arunta and Tennant regions (day 1);
  • the release of Tanami seismic data and interpretations (day 2); and
  • a synthesis of the evolution and mineral systems of the North Australia Craton and its relationship to other Australia Proterozoic terranes in Western Australia, South Australia, New South Wales and Queensland (day 3).

Following this meeting, Geoscience Australia and Northern Territory Geological Survey will jointly run a 5-day self catered excursion examining the geology and mineral deposits of the southeastern Arunta, including recently identified Neoproterozoic to Paleozoic rocks of the Irindina Supracrustal Sequence.

For further information, please email Dave Huston; or phone +61 (0)2 6249 9577.

4. World non-ferrous mineral exploration budgets rise

The Canadian company Metals Economics Group (MEG) has reported the preliminary results of its annual survey of the world's non-ferrous mineral exploration budgets for 2005. They report that an increase of around 38% was recorded as budgets rose to US$5.1 billion. This was just short of the US$5.2 billion reached at the peak of the last exploration cycle in 1997. They note that zinc exploration budgets rose by about 90% and nickel by almost 65%. The MEG media release with information on the survey is available on the company website.

For more information contact MEG directly.

5. Call for feedback from geochronology data users

Geoscience Australia is initiating the development of a standardised data format language for geochronology data. Such a format will be a crucial part of the interoperable data systems envisaged by Geoscience Australia and partners in CSIRO, SEEGrid and the mining industry to aid the effective exchange and use of geoscience data.

A fundamental aspect of developing standardised formats is the need to widely consult the user community to understand requirements. Thus Geoscience Australia is calling for feedback from all users of geochronology data ranging from specialist geochronologists to industry end-users.

A discussion paper has been prepared and is available by emailing Keith Sircombe; or phone +61 (0)2 6249 9543.
