A quartz vein occurs in a fissure paralleling Mississippian to Jurassic Bridge River Complex (Group) pelitic schists. The fissure dips opposite to that of the schist and forms along the contact of an albitite porphyry dyke, which has also been called "soda-granite" and is believed to be altered granodiorite related to the Cretaceous to Tertiary Bendor Intrusives (ie. a young phase of the Cretaceous Plutonic Complex). The porphyry intrusion comprises the hanging wall of the vein and is traversed by quartz stringers. The fissure contains abundant silicified fragments of the wallrock. The surrounding pelitic schist is pyritized. The quartz vein varies from several centimetres to 60 centimetres in width and contains scattered mariposite. Average assays grade 9.4 grams gold per tonne (Geological Survey of Canada Memoir 130, page 95).
