Name: BREN
The Bren showing is located south of Horsefly Mountain towards the eastern margin of the Upper Triassic to Lower Jurassic Nicola Group volcanic assemblage. The lowermost volcanic rocks consist of alkali basalt and alkali olivine basalt which, in this area, have been intruded by quartz porphyry dikes. A diorite syenite intrusion at Horsefly Mountain is probably of Lower Jurassic age but the age of the quartz bearing felsic dikes is not known.
The basaltic rocks have been silicified adjacent to the contacts with the quartz porphyry dikes and contain disseminated pyrite, pyrrhotite and arsenopyrite. Geochemical sampling carried out in 1982 indicates the presence of anomalous gold associated with sulphide mineralization.
