Abstract:

As mineral exploration seeks deeper targets under cover, the need for low cost and low impact subsurface imaging is increasingly important. A recent addition to the toolbox of geophysical methods is ambient noise surface wave tomography (ANSWT) which produces an S-wave velocity image of the subsurface using naturally occurring seismic signals ("noise") from waves, earthquakes, traffic, etc. - no active controlled seismic sources required. In this presentation, I will provide an introduction to the ANSWT method and show how it is applied for early-stage mineral exploration using some recent projects in Canada, South Africa and Australia.
