Reference information

Comments Geochemical anomaly, >1000 ppm Cu, >0.5 g/t Au. Location and geochemical anomalies for Cu and Au from Mowat (2007). Porphyry Cu-Au mineralization related to porphyritic monzodioritic stocks, plugs and dikes. Locally overprinted by albite-sericite-pyrite assemblage associated with Devonian orogenic gold veins.
