About this survey
Nineteen broadband magnetotelluric soundings at eighteen sites on two northeast trending lines across Riversleigh station, about 200 km north west of Mount Isa, Queensland. Moombarriga Geoscience recorded them for Red Metal between 13 and 19 October 2020 over exploration permit EPM 26157, to map conductive sedimentary sequences that could host stratiform lead zinc mineralisation. Sites are nominally 500 m apart, the closest pair 342.5 m. Each ran overnight on a Phoenix MTU-5C with MTC-150 and MTC-180 coils and 80 m dipoles, 10.5 to 25.3 hours, remote referenced and processed in EMpower; eight of the nine headers naming a remote name another site of this survey, and RVL1015 names CEN1000 of the neighbouring Century North programme. RVL2060 gave poor data and was reoccupied as RVL2060R; both are served. The transfer functions span 1.0e-04 s to 2912.9 s, 96 or 100 periods a site and 1,892 in all, with both off diagonal impedances present at 68 to 100 of them.
