Seismic reflection surveys to assist nickel and gold exploration in the WA goldfields

Abstract

In August 2006 pilot high resolution 2D seismic surveys were carried out on Lake Lefroy near Kambalda in WA to provide a ``proof-of-concept' for the use of surface reflection surveys for guiding exploration for nickel sulphide and gold in this area. The pilot survey demonstrated the basalt ultramafic boundary is usually a good reflector and mapped a number known and previously unknown faults and shears. A correlation was also noted between zones of reduced reflection and intrusive porphyries.
