Project: Reinterpretation of the Structural Geology of the Mount Polley deposit, Likely, British Columbia
The Late Triassic Mount Polley deposit is located outside of the town of Likely, northeast of Williams Lake. It is an alkalic copper porphyry deposit with significant gold values, found hosted in an intrusive complex in the Central Quesnel Belt, which extends along the eastern border of the Intermontaine Belt in southern British Columbia. The deposit itself formed in association to the intrusion of the Polley Stock, comprising syenite, monzonite, and monzodiorite, into the Nicola Group volcanics and alkali basalts. Significant post-mineralization faulting created mineralized blocks within the deposit. The complex structural geology of the deposit has limited exploration in the northeast zone of the deposit; therefore the purpose of this research project is to reinterpret the structural geology on a local and regional scale. This will be achieved through field mapping, systems analysis of structural orientations, and petrographic analysis of hand samples and drill core. Further research methods will be undertaken as required. It is anticipated that this research will enable a reconstruction of the deposit, leading to the generation of new exploration targets.
