hint of big major discovery

The prospectivity of this region has long been promoted by AGSO/Geoscience Australia and the Geological Survey of Western Australia (GSWA). The main conclusions of the AGSO study were:

• The granites of the Mount Webb region show all the important characteristics of granites associated with Cu-Au mineralisation elsewhere in the Australian Proterozoic including the Hiltaba Suite granitoids which host the Olympic Dam Iron Oxide Cu-Au- U deposit;
• The age of the Mount Webb granite is 1640 Ma which is consistent with other key mineralising events elsewhere in the Australian Proterozoic;
• Widespread sodic alteration and brecciation in the Mount Webb granite is also consistent with other Iron Oxide Cu-Au deposits.


• The Mount Webb Shear Zone was active during the emplacement of the granite allowing for the development of breccia bodies and focusing of fluid flow.
• Mineralisation is most likely to be associated either within shear zones or as a replacement of favourable host units, including the possibility of mineralisation occurring within the Mount Webb granite.

Following on from these positive indicators, the successful results generated by Aurora Gold and BHP, and the high level of activity within the Arunta Block in the NT, the GSWA undertook a detailed gravity survey over the Mount Webb area in late 2006, thus further underlining its belief in the prospectivity of this province.
The Mount Webb area consequently represents one of the last remaining under-explored, but highly prospective and large mineralised provinces in Western Australia. The promotion of the area by Geoscience Australia and the GSWA underpins the real prospectivity of the region.

The Mount Webb project contains all the right ingredients, including geology, age and setting, as well as significant mineralisation identified by limited previous work. The area is highly prospective for an extensive mineralised system and therefore has the potential to host a major Cu-Au (+/-U) discovery.
