 "abstract": "Eighty seven broadband and audio magnetotelluric soundings on 81 sites at Blue Bush East, in the Lawn Hill region about 270 km north of Mount Isa, Queensland. Moombarriga recorded them for Red Metal Limited between 6 September and 10 October 2020 to map a conductive sedimentary sequence with the potential to host stratiform lead and zinc, the thickness of the cover above it and the deeper structures controlling both. The sites lie on four lines running roughly north to south over about 50 by 22 km, nominally 1,000 m apart and 500 m on part of the southern line. Each recorded two electric and three magnetic channels on a Phoenix MTU-5C with MTC-150 or MTC-180 coils and 80 m dipoles, overnight, remote referenced against another site of the survey. The served transfer functions span 0.0001 s to 5825.42 s, 92 to 104 periods a station and 8,650 in all. Six sites were recorded twice and both recordings are served.",
