 "abstract": "Broadband and ultra-wideband magnetotelluric data were acquired across the Kalkaroo Cu-Au deposit and the surrounding Kalkaroo magnetic dome in the Curnamona Province, South Australia, between November 2020 and August 2021, jointly funded by the Geological Survey of South Australia and Havilah Resources Ltd through Accelerated Discovery Initiative project RD01-117, with logistical support in the field from Havilah Resources. The survey combined a dense grid of approximately 126 sites at about 300 m spacing over the deposit with a regional grid of approximately 104 sites at about 1.2 km spacing across the magnetic dome, acquired over multiple campaigns using Phoenix MTU-8A systems operated by Geoscience Australia and Phoenix MTU-5C and LEMI-423 systems hosted by the University of Adelaide through the AuScope ANSIR Research Facility for Earth Sounding, supported under the Australian Government's NCRIS; parallel instrument comparison tests and remote-reference deployments supported data quality assessment and processing. This package carries the 216 released EDI transfer function files, 174 audio- frequency (AMT) and 42 broadband (BBMT).",
