Results of various airborne EM systems over a target of high conductance

Abstract

The ability to detect and characterize targets of high conductance (>2 000 S) has become a primary technical criteria for airborne EM surveys being flown to explore for nickel sulfide deposits. A variety of commercial airborne EM systems have flown over the same high conductance target as well as a prototype system. These results show what the current capabilities of the various systems and as well, what type of future technology is required to significantly improve the high end conductance aperture of airborne EM technology.
