This occurrence is located south of Divelbliss Creek and west of Cabin Glacier. The area is underlain by rock of the Lower Jurassic Unuk River Formation, Hazelton Group. The formation is composed pri- marily of thick-bedded epiclastic volcanic rocks and lithic tuffs with closely associated pillow lavas, carbonate lenses and thin-bedded siltstone.
Alteration and deformation are complex and are related to re- gional folding and Jurassic and Tertiary plutonism. In addition, the degree of dynamic metamorphism increases toward the South Unuk River cataclasite zone (Grove, Bulletin 63).
Chalcopyrite is reported to occur with quartz in an unspecified host rock (Newmont Map).
