Abstract

FLAIRTEM (Fixed Loop AIRborne Transient Electromagnetics) is a hybrid ground-air system that combines the use of a very large ground based transmitter loop with an airborne receiver. The method was developed in Australia during the period 1991-93. Preliminary FLAIRTEM test surveys were completed in Australia and Papua New Guinea (PNG) over a number of mineral deposits. Results are presented over a 40-mt copper sulphide ore deposit in the Freida River area of PNG. Results from modelling suggests that the FLAIRTEM method could have greater sensitivity to buried conductors at depths of over 100 m than conventional airborne systems.
