The area is underlain by the Hazelton Group which is a northwest trending belt of folded volcanic rocks which contains a thick sedimentary sequence infolded along a synclinal axis. This group is bounded on the west by the Coast Crystalline Complex and on the east by the Bowser Basin.

The host rock is the Lower Jurassic Texas Creek Batholith which is a coarse-grained hornblende granodiorite. The occurrence consists of a small quartz vein which is between 0.2 and 0.5 metre wide. The vein strikes southeast and dips 35 degrees to the southwest and is traceable for about 15.2 metres. The vein consists of quartz, fragments of wallrock and is sporadically mineralized with chalcopyrite, galena, sphalerite, pyrite and barite.
