The Owl Mountain showing lies on Owl Mountain, adjacent to a microwave tower located about nine kilometres north of Pemberton. The area is underlain by a large northwest trending roof pendant of Upper Triassic Cadwallader Group volcanic rocks, preserved within hornblende granodiorite of the Upper Cretaceous Spetch Creek pluton.
Skarn-type mineralization consisting of massive magnetite- pyrite-arsenopyrite lens occur in fractured andesite proximal to an intrusive contact. Secondary malachite and annabergite have been observed on fracture surfaces.
Gold mineralization appears to be associated with arsenopyrite and is considered to be patchy. A 1.07-metre sample collected in 1934 graded 4.8 grams per tonne gold (Assessment Report 361). De Quadros reported an assay of 75 grams per tonne gold from andesite containing disseminated pyrite and arsenopyrite (Assessment Report 15597).
