The ML showing occurs with the Mount Alex plutonic complex consisting of granodiorite, quartz diorite, quartz monzonite and diorite of probable Middle Jurassic age and overlain by basalt of Miocene to Pleistocene age. The plutonic complex is interpreted to intrude older rocks of the Carboniferous to Jurassic Cache Creek Group which are exposed to the east of the complex. The showing consists of coarse chalcopyrite grains in a narrow quartz vein (2 to 3 centimetres wide) near the contact of altered hornblende granodiorite with biotite granodiorite. Alteration minerals include epidote, sericite and potassium feldspar. Altered boulders of granodiorite containing disseminated chalcopyrite have also been found within the area covered by the ML claim group.
