Abstract
The global demand for mineral resources is increasing every year, with now even a strong push for green and high-tech technologies. Considering the ever-increasing hope of exploring these resources at depth, particularly at near mines or near existing infrastructures, new and improved approaches for integrating available data and use them to optimize exploration and mining are required. In this work, we have revisited an existing legacy active-source 2D seismic data acquired over Garpenberg volcanic-hosted massive sulphide (VMS) deposit. Given the strong noise contamination observed in the active-source data, we argue an approach involving the use of active-and passive-seismic data recording would be optimal for deep exploration and characterization of the top of the orebody illustrating its potential for targeting even steep geometry mineralized zones. The reprocessing reveals a strong reflection that may be associated with a VMS mineralization or contact that hosts the mineralization.
