About this survey

Audio magnetotelluric survey of the Kalman and Mt Philp prospects south of Mount Isa, Queensland. Zonge recorded 92 soundings on two tracks at about 200 metre spacing between 18 March and 17 April 2020 for Hammer Metals, under round three of the Queensland Collaborative Exploration Initiative. Five channel Phoenix receivers with 100 metre dipoles ran a median of nearly 14 hours a site, remote referenced on all but one sounding, processed in EMpower and reviewed in Geotools. AusMT serves 91 of the released edited set of 92 transfer functions, as the custodian wrote them apart from a repaired acquisition date; station 61 is withheld because it declares a different frame at every period. Every curve sits on one shared hundred period grid from 0.0001 to 2912.9 seconds, but the median longest usable period is 109 seconds and only two stations reach past 500 seconds. Three served files declare a rotation their source export does not; README.md sets out both.
