We have acquired new 2D seismic reflection data at the Kylylahti Cu-Au-Zn mine area, Finland in 2016 as a part of the COGITO-MIN project. The aim of the project is to develop cost-effective mineral exploration methods with special focus on seismic techniques. Seismic reflection profiling was done in two parallel profiles approximately perpendicular to the known Kylylahti massive sulfide deposit and intersecting the HIRE-seismic reflection profiles previously acquired in the area. New data correlate well with the HIRE seismic profiles, yet they have higher frequency content. Ore hosting rock assemblage is expected to be internally highly reflective because of varying acoustic impedances of constituting rocks. Continuous reflections observed in one of the new profiles are likely originating from the contacts between mica schist and sulfide-bearing black schist, the latter typically enveloping the ore-hosting Outokumpu assemblage rocks.
