The geology of the Noranda Central Camp has been systematically mapped and studied since the early 1930’s. It consists of a series of five bimodal felsic-mafic volcanic cycles separated by cherty exhalative horizons which represent breaks in volcanic activity permitting deposition of massive sulfide lenses of economic interest.
The volcanic series are bordered to the west by the synvolcanic Flavrian-Powell Batholith and the syntectonic Lac Dufault Pluton to the east. Formations have a gentle eastward dip in a caldera type structural setting bounded by two major east-northeast striking faults: the Hunter Creek Fault to the north and the Beauchastel Fault to the south.
Several synvolcanic faults crosscut the stratigraphy providing ancient pathways for hydrothermal fluids to reach the sea floor. In conjunction with the exhalative horizons, these faults are the main mechanisms responsible for localization of massive sulfide lenses - best summarized in the following image.
Falco Resources properties cover approximately 90% of the Central Camp, divided into 26 blocks totaling 287 mining titles covering 6,040 ha. For clarity purposes, they are grouped into three main geographical designations – Ribago-Despina, Waite Amulet and Ansil - in addition to the isolated Newbec block.
