Quartz veins with a general northwesterly trend cross- cut fine-grained granite of the Lower Cretaceous, Nelson Plutonic Rocks and augite porphyry and tuff of the Lower Jurassic Elise Formation. The veins vary from stringer size to about 0.4 metres in width and the quartz gangue has erratic sulphides as small grains or small masses. Quartz filled fractures in aplite dykes also carry small amounts of sulphides. The pockets, or lenses, of sulphides in the vein also contain some sphalerite and galena and are typically highly oxidized in the exposures near surface.
