 "abstract": "Fifty two audio and broadband magnetotelluric soundings on two lines over the Rhea project of FQM Exploration Australia in Western Australia, acquired in November 2017 by Moombarriga Geoscience and released by the Geological Survey of Western Australia as MAGIX registration 72579. Line 1 holds 38 soundings over about 17 km and Line 2 holds 14 over about 7 km, about 43 km apart, at a nominal 400 m spacing. Each site recorded Ex, Ey, Hx, Hy and Hz on Metronix ADU-07e receivers with MFS-06e coils and nominal 50 m dipoles, processed in Metronix ProcMT. Every sounding starts at 0.0001 s and carries a tipper; 16 reach 162 s and the other 36 stop between 0.14 s and 12 s. The sensors were laid out to magnetic north and no declination was applied.",
