With the Australian Lithospheric Architecture Magnetotelluric Project (AusLAMP) deployment across South Australia nearing completion, the subsequent 3D inversion modelling of the magnetotelluric (MT) data and integration with other geophysical, geochemical and geological data will provide a new fundamental precompetitive dataset for the state. It will highlight areas of enhanced conductivity in the crust, which have been shown to be a potential proxy for fertile crust, one characteristic for establishing mineral deposits. However, to confidently map the high conductivity zones extending into the surface cover sequence, closely spaced broadband MT surveys are required. This article summarises the results of a recently published closely spaced (1 km site spacing) broadband MT survey across the Beverley uranium deposit, located east of the northern Flinders Ranges. The results provide an example of how geophysical surveys contribute to the scale-reduction process that is critical for mineral exploration success. Follow-up high density MT surveys, such as that over the Beverley uranium mine, resolve crustal-scale faults that can control the location of mineral deposits.
