 "abstract": "Seventy nine broadband magnetotelluric soundings over the Big North East prospect in the Warrina project area, on the Mabel Creek Ridge north east of Coober Pedy, South Australia. Moombarriga Geoscience recorded them for Alliance (SA) Pty Ltd between 11 November and 7 December 2011, on two blocks 1.6 km apart at a nominal 400 m station spacing, targeting iron oxide copper gold mineralisation under Eromanga Basin cover. Acquisition was five channel with Phoenix MTU-5A receivers, induction coils and nominal 90 m electric dipoles, a median 18.8 hours per site, with 63 of the 79 processed against a remote reference. The delivery is cross spectra written by Phoenix MT-Editor 0.99.2.106 and every file is served byte for byte in the frame it declares, which is zero. Each carries impedance and tipper with variances on 76 to 84 frequencies, 320 Hz to a median longest period of 2941 seconds. Released open file by the Geological Survey of South Australia through SARIG.",
