Regional Airborne Magnetic Intensity and Interpreted Graben. White dotted lines define an interpreted wedge bounded by the Boundary Fault (east) and a fault east of the Whipsaw Fault that approximately follows the Nicola Princeton Group contact. Within the wedge thus defined, the intensity of the magnetic features is lower than that of the magnetic highs outside the wedge, both to the east (Copper Mountain) and the west. The interpretation therefore is that the area inside the wedge may be a complex graben, possibly with larger downward displacement in the south relative to the north(3).
