 "abstract": "One hundred and thirty two magnetotelluric and audiomagnetotelluric soundings over the Eloise and Jericho copper deposits, about 60 km south east of Cloncurry, Queensland. Moombarriga Geoscience recorded them for AIC Mines between 11 July and 13 August 2024 on nine lines at a nominal 250 m spacing, to test whether magnetotellurics can image iron sulphide copper gold systems under conductive cover. Each site took two electric and three magnetic channels on a Phoenix MTU-5C, 40 m dipoles, coils laid to magnetic north; the 131 files that print a recording duration ran 2.0 to 23.9 hours, median 16.3. Processing was remote referenced in Phoenix EMPower and exported through Geotools; one station is served from a later reprocessing by Ohmega Geoservices and 31 more reprocessings are recorded but not served. The transfer functions span 0.0001 s to 2912.71 s, 44 to 100 periods a site and 12,583 in all.",
