Abstract

Summary

In the last five years the minerals exploration industry has placed greater emphasis on the mapping of targets of high conductance. In response to this end user requirement, the VTEM system has been modified to allow the recovery of an enhanced conductance measurement. Field results show this new parameter to have improved sensitivity to targets of high conductance, approximately doubling the performance over the previously available results.
