The objective of the 2012 exploration program on the 33 CARATS SOUTH project was to better investigate the potential of Bohier tonalite to host a gold-copper porphyry deposit. The Bohier tonalite and its contact with the granodioritic phase of the felsic Erasme pluton was targeted where it was intersected by DIOS gold dispersal train in till. Magnetic and spectrometric-K data as well as additional mapping were also used to center the exploration efforts and test other targets. Positive rock sampling of outcrops and glacial floats confirmed the presence of significant porphyric gold-copper mineralization within the Bohier tonalite. The recent results are considered very significant as it indicates that this part of the Upper Eastmain volcanic belt has excellent potential for the discovery of an economic gold-copper porphyry deposit related to the Lac Erasme pluton.
