Summary A new surface-based geophysical method of subsurface exploration, Seismic Full Waveform Inversion (FWI) was compared to two other traditionally used surface-based geophysical methods, Electrical Resistivity and Microgravity. The Seismic FWI method was shown to be capable of identifying subsurface anomalies, in this case, flooded underground mine workings, in the geologic setting of this particular site, with less limitations than the other two techniques. This was field verified with confirmation drilling of suspect anomalies and non-suspect locations and down the borehole sonar mapping of the mine workings when encountered. However, it should be noted, that the Seismic FWI method is nearly twice the cost of the other two geophysical methods.
