 "abstract": "A remote referenced tensor magnetotelluric survey over eight mineral prospects in the Peake and\nDenison Inliers of northern South Australia, about 42 km north of William Creek. Zonge\nEngineering and Research Organization (Aust) Pty Ltd acquired 104 soundings for Minotaur\nExploration Ltd during November 2020 on exploration licences EL 6221, Big Perry, and EL 6270,\nDavenport, under an Accelerated Discovery Initiative Round 1 grant, to rank magnetic and gravity\ntargets for iron oxide copper gold and Broken Hill type mineralisation under 50 to 250 m of\ncover. Stations sit at a nominal 200 m along eight lines of 19.2 km in total, alternating short\naudio band and overnight broadband recordings on Phoenix MTU-5C receivers with MTC-150 coils and\n100 m dipoles. Every station reaches 10 kHz and the longest period runs from 364 to 2913 s.\nReleased open file by the Geological Survey of South Australia. All 104 files are served byte\nidentical to the custodian's delivery.",
