 "abstract": "Magnetotelluric soundings recorded by Moombarriga Geoscience for Alchemy Resources in 2011 at the Magnus project, Western Australia, across the Karalundi Formation and the Narracoota volcanic sequence. Audio-magnetotelluric data were recorded for about an hour at each of 91 stations 100 m apart on two profiles, 0.0001 s to 0.18 s. Broadband data, which the report says were recorded for at least 12 hours, were delivered for 31 sites, 0.0031 s to between 1449 s and 2941 s: 20 at roughly every fifth audio station, which therefore carries two independent recordings served under separate names, and 11 on a third profile, Central Bore. Phoenix MTU-5A receivers, MTC-30 and MTC-50 coils and 25 m dipoles; Phoenix processing, exported from WinGLink. A vertical coil could not be buried at many sites, so the tipper is published at 78 of the 122 stations. Nothing is rotated and no static shift is applied.",
