Minor felsic porphyry dykes and biotite lamprophyre dikes are locally known to penetrate the volcanics. Auriferous quartz veining within carbonatized Mafic and Ultramafic volcanics has historically been of interest on this property. Mafic and Ultramafic metavolcanic rocks are exposed in the Royal Oak pit, which is located.
