Volcanogenic-hosted massive sulphide (VMS) deposits show a strong seismic contrast (mainly due to their density) against almost all lithological host rocks therefore justifying their direct targeting using seismic methods (Salisbury et al., 2000; Malehmir et al., 2012 and references therein; Malehmir et al., 2013) when there is adequate signal-to-noise (S/N) ratio and suitable geometry. While there are earlier published accounts illustrating the use of seismic methods for direct targeting of deep-seated VMS deposits elsewhere (Matthew, 2002; Malehmir and Bellefleur, 2009), a number of attempts were done in Europe during the early 90s for this purpose and these have been overlooked for unknown reasons.
