Mineral exploration in mountainous areas is challenged by several factors. The accessibility is not straightforward due to steep terrains and, in some cases, also due to forest coverage; thus, making both exploration and development plans far more expensive. A comprehensive understanding of the subsurface is of paramount importance to target the most promising prospects and to reduce the footprint – and the cost – of exploration and production activities. Satellite imagery and airborne acquisition techniques can be used to cover large areas in an economic manner and to gain a preliminary knowledge of the subsurface. Unfortunately, these techniques lack the resolution required to infer the geologic setting at depth and to build a structural model with adequate confidence; this is the time when it becomes necessary to step into ground exploration.
