1. Australian Mineral Exploration Review for 2005

Geoscience Australia has released a review of mineral exploration highlights in Australia for the year 2005. The review examines levels and trends in exploration in a national and global context. It also presents highlights of government programs that have released information to support exploration during the year. Overall expenditure in 2004-05 rose by 31% to $1028.3 million. 39.3% was spent on the search for new deposits. Total global non-ferrous mineral exploration budgets rose 38% to an estimated US$5.1 billion. Western Australia received 59% of Australian mineral exploration spending in 2004-05 as spending rose in all States except Victoria. Gold remained the main target but its share of spending was eroded by increased spending on nickel, copper, iron ore, coal and uranium. Exploration resulted in a substantial number of drill intersections of economic interest, the most notable being the discoveries of copper-gold mineralisation at Carrapateena (Gawler Craton), mineral sand in the Eucla Basin, and gold at the Trident deposit (Yilgarn Craton).

Copies of the review may be downloaded from the Geoscience Australia web site.

2. Tanami Seismic Workshop, June 2006

The Evolution and Metallogenesis of the North Australia Craton conference, a joint conference between Geoscience Australia, the Northern Territory Geological Survey and the Geological Survey of Western Australia will be held on 20-22 June in Alice Springs. Topics will include the evolution and metallogenesis of the Arunta and Tennant regions, metallogenesis and crustal architecture of the Tanami region as established using land seismic, and continental-scale drivers of mineralisation in the North Australia Craton. A post-workshop excursion will be run 23-27 June to examine the metallogeny and geology of the eastern Arunta region, including the Nolans Bore REE-P-U deposit.

The complete program and registration information on the Workshop can be found on our Conferences and Seminars page.

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

3. New SHRIMP results in OZCHRON

New SHRIMP geochronology results and interpretations are now available through OZCHRON for samples from areas including the Amadeus Basin, Arunta Inlier, Birrindudu Basin, Davenport Geosyncline, Mount Isa region, Pine Creek Orogen, Tanami Inlier, New England Fold Belt and the Lachlan Fold Belt.

For further information, please email Narelle Neumann; or phone +61 (0)2 6249 9429.

4. New Yilgarn synthesis: release of Geoscience Australia Record 2006/05

This Record is a DVD open file release of the pmd*CRC Y2 project's final report to sponsors. The DVD contains a full colour 276 page PDF report with links to extensive appendices. The appendices include time-space syntheses, 3D earth models or maps as GOCAD objects, mantle tomography, gravity data inversions, seismic sections and data, tables of rock properties, and PowerPoint presentations. A copy of the DVD can be obtained on the Geoscience Australia web site or by emailing the Sales Centre.

For more information, please email Richard Blewett; or phone +61 (0)2 6249 9713.

5. Update on geophysical survey data acquisition

Requests for quotation closed on Wednesday 31 May for provision of gravity coverage in three new survey regions of Western Australia: Murchison, Webb and Western Tanami. These surveys will proceed subject to successful land access negotiations. Geoscience Australia will manage the gravity data acquisition program in the three new survey regions.

The status of current surveys is:

  State Survey % Complete Gravity Stations Flight Lines Spacing Ground Clearance Comments
Paterson WA Airborne magnetic & radiometric 73% N/A east-west 400 m 60 m
Murchison WA Gravity N/A 3,600 new east-west 2.5 km N/A Survey covers all portions of the Belele, Cue, Glengarry & Sandstone standard 1:250 000 Map Sheet areas
Webb WA Gravity N/A 4,100 new east-west 2.5 km N/A Survey covers all portions of the Wilson, Webb, Ryan & Macdonald standard 1:250 000 Map Sheet areas
Western Tanami WA Gravity N/A 3,700 new east-west 2.5 km N/A Survey covers all portions of Gordon Downs, Billiluna & Lucas standard 1:250 000 Map Sheet Areas
Bowen-Surat North QLD Airborne magnetic & radiometric 60% N/A east-west 400 m 80 m
Isa A QLD Gravity 53% 6,700 new east-west 2 km N/A  
Isa South West QLD Airborne magnetic & radiometric 57% N/A east-west 400 m 80 m
Jervois NT Gravity N/A 3,600 new east-west 2 km N/A Survey is expected to commence in the 1st week of June. The survey will cover the Huckitta, Tobermory, Illogwa Creek & Hay River standard 1:250 000 Map Sheet areas.

For further information, please email Murray Richardson; or phone +61 (0)2 6249 9229.

6. Geophysical data releases

Final located data and grids from airborne magnetic and radiometric surveys over the Gascoyne and East Yilgarn areas of WA will be released on Wednesday 7 June at 0900 AWST. The final datasets may be downloaded from the Geoscience Australia Geophysical Archive Data Delivery System (GADDS) facility at no charge.

For further information, please email Murray Richardson; or phone +61 (0)2 6249 9229.
