Focus areas Musgraves (A1), Darling Curnamona Delamarian (DCD) and Upper Darling Floodplain (UDF) referred to in text. Existing coverage across southern half of Western Australia and planned surveying along eastern and northeastern margins of the state is 100% funded by the Geological Survey of Western Australia. Along with funding from the Federal Governments Exploring for the Future (EFTF) programme, the AusAEM programme has been expanded with funding from the Geological Surveys of Western Australia and Queensland, combined with valuable in-kind support from all Australian state and territory geological surveys.to semi-detailed AEM respectively(c)the continuity of key conductiveBogan river.
