15 specimens from the outcrop indicate that the layering and preferred orientation are due to magma flow and that the intrusion is probably not tilted through 90 degrees. The level exposed by erosion is probably close to the original roof of the intrusion. The most probable age of intrusion is the waning stages of the Delamerian Orogeny. The proportion of norite in the outcrop is lower than that of gabbro but the presence of hypersthene and very minor olivine are indications of basic and possibly ultrabasic cumulates below. The metallogenic potential of the intrusion (for copper, nickel, chromium, platinum and lithium) has not been fully evaluated.
