We present a feasibility study for surface wave tomography for mineral exploration. We apply a typical seismological approach, the Two Station Method to a hard-rock site, at exploration scale. Even with this method, we are able to separate the two propagation modes typical of these sites. After windowing the traces by picking one propagation mode in the group velocity matrix, we pick the phase velocity dispersion curve in the cross-multiplication matrix. We finally propose a plot consisting of slices of tomographic pseudo volumes, which allows us to understand the penetration depth we can have. Furthermore, it gives us a first indication of the velocity anomalies in the area.
