 "abstract": "Twenty-nine broadband magnetotelluric soundings at 28 sites on the Moly B line of the Warrawagine project, about 90 km northeast of Marble Bar, Western Australia, recorded by Moombarriga Geoscience for Muccanabout Pty Ltd between 8 and 22 April 2026 beside a dipole-dipole induced polarisation survey. Twenty-two sites run about 8.4 km northeast at a nominal 400 m spacing, with three-site infill lines about 1 km northwest and 800 m southeast of it; MolyB_021 was recorded twice and both recordings are served. The report has every site recorded overnight on a Phoenix MTU-5C with three induction coils; the files print 80 m dipoles. Processing in EMpower used a remote site about 12 km away. Served periods run 0.0001 s to 5,825 s, 95 to 104 a station, each with a tipper. The report states that declination was corrected in processing, so the frame is geographic; nothing is rotated.",
