1. Geophysical Data Release West Tanami Region, WA - Phase 2

The Geological Survey of Western Australia (GSWA) and Geoscience Australia (GA) announce the release of airborne geophysical data over the west Tanami region of Western Australia covering the Billiluna and parts of the Gordon Downs and Lucas 1:250 000 Sheet areas. The west Tanami region is one of the most encouraging gold prospects in Australia. Since the mid 1980s over 10 million ounces of gold has been discovered in this poorly outcropping region of Palaeoproterozoic sediments, volcanics and granitoids that straddles the border of Western Australia and the Northern Territory. New data in this release is comprised of combined magnetic, gamma-ray and elevation located data and grids from a survey flown for GSWA and GA by UTS Geophysics in 2002 and from 3 private company surveys flown between 1989 and 1995. Release date: 1 July 2003.

2. 3D model of the Tanami Release

Geoscience Australia in collaboration with the Northern Territory Geological Survey have released a 3D model of the Tanami as part of The North Australia Project. This model, which was demonstrated at AGES in March, can be viewed as a VRML. The VRML includes modelled surfaces for the Frankenia dome and major fault systems in the Tanami, as well as the 2D cross-sections from which the 3D model was derived. Additional information accessible in the VRML include images of DEM, aeromagnetics (both RTP and TMI), Bouger gravity, gravity worms and solid geology, and point data for mineral deposits/prospects and geochronology.

3. Geoscience Australia Annual Minerals Seminars - Advanced Notice

Geoscience Australia will be hosting two one-day seminars to present the results of its research to the mineral exploration community later this year. Full details of the seminars are yet to be completed. Currently it is planned to hold a one-day seminar in Brisbane in late November 2003 and a repeat of this seminar will be held in Perth in early December.

4. Gravity Data Set Release Broken Hill - Menindee, NSW

Geoscience Australia will be releasing the Broken Hill - Menindee gravity data set on 25 July 2003. The data set consists of 182 new gravity stations and 20,514 existing gravity stations. The new data were acquired at a station spacing of 2km x 2km in May 2003 as part of Geoscience Australia's ongoing program to add to the National Gravity Database. Purchasers of the 2003 National Gravity database release will be supplied with this update free of charge on request.

5. Broken Hill Exploration Initiative Conference

The next Broken Hill Exploration Initiative Conference (BHEI2003) will be held at the Broken Hill Entertainment Centre from Monday 7th to Wednesday 9th July 2003. Following the conference there will be a three-day excursion to see the Proterozoic-Palaeozoic and regolith geology of the Koonenberry region, north of Broken Hill.

Themes to be covered as both oral and poster presentations include copper-gold mineralisation, new airborne technologies, regolith studies, opportunities around the Curnamona margins, lead-zinc mineralisation in the Broken Hill Block and tectonic evolution of the Willyama Supergroup. Highlights include the latest information on geochronology, lead isotopes, first images from the Falcon airborne gravity survey, interpretation of hyperspectral data, and an account of operations by Perilya and Consolidated Broken Hill since their takeover of the Broken Hill mining leases. Abstracts of all talks and posters will be published as Geoscience Record 2003/13 (compiled by Matti Peljo) and made available through the the Geoscience Australia Sales Centre or as a download from the BHEI web site.
