We present results showing recent trends in the value of modeling studies, acquisition geometry, and processing techniques in seismic imaging of massive sulfides. Forward modeling is valuable in assessing the impact on seismic wave scattering by host rock heterogeneity in delineating exploration targets. Favourable settings for seismic imaging and resolving power for mineral exploration targets are identified. With borehole access, we can take advantage of an acquisition geometry that combines surface and downhole recording for quality control on the velocity field and statics. Improved processing of seismic data demonstrated the usefulness of finding optimal azimuths to characterize the strike, dip and amplitude variations of seismic anomalies. The data used in this paper includes borehole logs and 3D seismic data that were acquired in the Trill area of the Sudbury basin in Ontarion, Canada (Milkereit et al., 2000).
