Minerals Alert June 2011

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

1. Workshop on Geoscience Australia’s Northern Territory Pine Creek AEM Survey Data

There will be a half-day workshop in Perth, Western Australia on Tuesday 7 June, 2011 starting at 9:00am, at The Celtic Club Inc., 48 Ord Street, West Perth.

Registration forms containing details of the workshop in Perth are available online, and further details are available in the Australasian Institute of Mining and Metallurgy (AusIMM) Uranium Conference web page.

The Pine Creek airborne electromagnetic survey results are now available as a free download.

To obtain further details on the workshop, please email mike.craig@ga.gov.au; or phone +61 2 6249 9453.

2. 34th International Geological Congress (IGC)

The Second Circular announces the opening of abstract submission, the Scientific Program, GeoHost opportunities, field trips and the daily schedule for this prestigious event.

Block out your calendars and make your travel plans for IGC on 5-10 August 2012. The Second Circular for the 34th IGC is now available for download.

To obtain further details on the IGC Congress please email paul.kay@ga.gov.au; or phone +61 2 6249 5829.

3. Frome AEM survey Phase 1, South Australia, additional data release

As an adjunct to the Phase 1 (contractor delivered) data which was released in March 2011, Geoscience Australia has released GIS-ready geolocated JPEG images and GOCAD triangulated surfaces (tsurfaces) of those data. The geolocated JPEG images have an associated worldfile with UTM coordinates (Map Grid of Australia Zone 54 using the Geodetic Datum of Australia 1994) and can be opened in any GIS or image display software, but the GOCAD tsurfaces require specialist software to view.

More information and a link to the download site are available online.

To obtain further details, please email ian.roach@ga.gov.au; or phone +61 2 6249 9683.

4. Uranium mineralisation events – new constraints

Two reports are now available on the geochronology of uranium mineral systems in Australia.

The report Uranium mineralisation events in Australia presents new geochronological data for the Nolans Bore, Oasis, Kintyre, Mt Gee-Armchair and Maureen uranium deposits. For most of these deposits the dating results are the first to be published. Descriptions of the geological settings and mineralisation are also included. These data provide new constraints on the timing of uranium mineralisation in relation to regional geological events, thereby improving genetic and exploration models for these mineral systems.

The Lake Frome region in South Australia hosts Australia’s largest known resources of sandstone-hosted uranium, including the Beverley, Four Mile and Honeymoon deposits. The report, SHRIMP U-Pb detrital zircon results, Lake Frome region, South Australia, dates six samples of Cenozoic and Mesozoic host sedimentary rocks in the vicinity of the major deposits. These results provide maximum age constraints on the timing of uranium mineralisation within the Cenozoic and Mesozoic basins, which will assist in building an event chronology for the uranium mineral system.

5. Update on geophysical data releases

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