Minerals Alert August 2012

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

1. Australian Operating Mines Map 2011

The recently released Australian operating mines map shows operating mines, developing mines and selected mineral deposits in Australia at 1:10 000 000 scale. This map broadly illustrates the geographic distribution of the mines and deposits and the range of selected, largely grouped, commodities. This information is superimposed on a generalised surface geology map of Australia and an aeromagnetic image in grey scale. It is available as a free download on the Mineral Exploration Promotion Section.

2. 34th International Geological Congress (IGC), Brisbane, Queensland, 5-10 August 2012

The 34th International Geological Congress is being held in Brisbane 5-10 August. This event has attracted more than 5200 registrations from around the world, including over 1500 people from the resources industry.

Geoscience Australia will be presenting several mineral exploration related papers to the congress, including:

  • The National Geochemical Survey of Australia: overview and results to date
  • Principal component analysis of the National Geochemical Survey of Australia data
  • National ASTER geoscience map
  • Seismic methods for hard rock mineral exploration
  • Recent magnetotelluric surveys along national deep seismic reflection transects
  • Airborne electromagnetic surveys and exploration of uranium, base metal and gold deposits
  • Targeting iron ore-copper-gold deposits in Australia: essential criteria and prospectivity mapping
  • Radiogenic isotope ratios and their bearing on volcanic-hosted massive sulfide and komatiite-associated nickel sulfide endowment of Archean terranes
  • Magnetic and gravity datasets of continental Australia
  • Geophysical constraints for unravelling the Proterozoic evolution of Australia’s mineral deposits as indicators of tectonic processes: some examples from Proterozoic Australia
  • Tectonic models for Proterozoic Australia: implications from the magmatic record
  • Geological, geometric and geochronological constraints on the Proterozoic northern and eastern margins of the Gawler Craton, South Australia
  • SHRIMP U-Pb xenotime analysis: calibrating a path through severe multi-element matrix effects
  • Why Australia has so much uranium: metallogeny, exploration and mineral potential of uranium mineral systems
  • Minerals and Energy: Supporting Economic Growth in Australia and the Region
  • Virtual Exploration Geophysics Laboratory (VEGL): a browser-based interface to supercomputer inversions of geophysical data
  • High-resolution, regional-scale 3D inversion modelling using the National Computational Infrastructure
  • National deep crustal seismic reflection surveys from 2006 to 2011
  • Using a mineral systems approach to assess potential for uranium mineralisation in greenfields regions.

Geoscience Australia will also be releasing its new book Shaping a nation: A geology of Australia, which has a number of chapters relevant to the minerals industry.

3. Update on geophysical data releases

Geoscience Australia will be managing the data acquisition program in New South Wales, Queensland, Western Australia and the Northern Territory.

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