Geoscience Map 2007-1 presents a 1:50 000-scale geology map of the Mount Polley area. This geological map provides new insight into the geology, geochronology and mineral potential of the Nicola Arc in the Quesnel Lake region of central British Columbia. It presents the results of new mapping and compilation of University and private industry research designed to document the geologic and metallogenic evolution and architecture across this part of the Quesnel terrane.


Cu-Au±Ag porphyry and propylitic Au replacement associated with alkaline intrusive centres at the Mount Polley mine and the QR mine, respectively, comprise important exploration models for this part of the Nicola Arc. Delineation of additional reserves and new exploration targets by Imperial Metals Corporation and Cross Lake Minerals Ltd. at Mount Polley and QR mines underlines the potential for new discoveries and mines in correlative rocks in the area.


The Mount Polley survey was delivered through support from Geoscience BC and a Geoscience partnership developed between Abacus Mining and Exploration, Imperial Metals Corporation and Nova Gold Corporation to study British Columbian alkaline porphyry copper-gold deposits.
