Tanami Land Seismic Acquisition Proposal

Geoscience Australia, in collaboration with the Northern Territory Geological Survey (NTGS) and the Australian National Seismic Imaging Resource (ANSIR), are planning a seismic acquisition program in the Tanami region in fiscal year 2004-2005.

The purpose of this program will be to determine the 3D architecture of this region, thereby ascertaining regional controls on lode gold mineralisation. At this time we ask interested parties to comment on this proposal which can be obtained from David Huston at Geoscience Australia or Leon Vandenberg at NTGS.

Geoscientists from Geoscience Australia and NTGS will be available at the AGES 2004 conference (23-24 March in Alice Springs, www.minerals.nt.gov.au/ntgs) to discuss the proposal. David Huston may be contacted at David.Huston@ga.gov.au or by phone on +61 (0)2 6249-9577.

Yilgarn Seismic Reflection Traverses

The Australian National Seismic Imaging Resource (ANSIR) will be commencing a series of mine scale seismic reflection traverses over a number of active and prospective mine sites in the Yilgarn region of Western Australia between February and April. Approximately 120 km of seismic data will be acquired over 20 lines at 8 sites.

The work will attempt to delineate near surface structures controlling mineralised zones over different geological environments. This is a component a MERIWA project M363 involving four companies, who are providing the acquisition funding, and Curtin University. ANSIR at Geoscience Australia is providing the expertise and project management to undertake the seismic acquisition phase of the project.
