About this survey

Seventy eight broadband magnetotelluric soundings at Greatland Gold's Tabletop project in the Paterson region of Western Australia, recorded by Moombarriga Geoscience between 11 September and 4 October 2023. Sixty six form a grid about 6.2 km across over the Tabletop East target, neighbours about 0.3 km to 0.8 km apart; twelve lie on one line about 3.5 km long over Tabletop West, which the contractor's report calls Tabletop North. Phoenix MTU-5C and MTU-8A receivers recorded two 80 m dipoles and three induction coils for 11.5 to 50.5 hours, and every sounding was processed in EMpower against a remote reference. Periods run from 0.0001 s to between 728 s and 11,651 s, with impedance and tipper at every station. The files declare no rotation; the report says declination was corrected in processing, while every file prints a declination of zero. Nothing is rotated and no static shift is applied.
