The Tower claims are located approximately 15 kilometres south east of the community of Sayward, between Provincial Highway 19 and the headwaters of Big Tree Creek.

The area is underlain by massive and amygdaloidal upper Triassic Karmutsen Formation basalts with minor interbedded tuff which has been intruded by granodiorite and quartz diorite. The intrusive rocks are part of the Jurassic to Cretaceous Coast Plutonic Complex.

The volcanic rocks have been altered, fractured and locally mineralized by chalcopyrite and minor bornite within 900 metres of the intrusive contact.

The Tower claims were staked in 1972 and prospected the following year.
