Capsule Geology

The Wayne showing is located on the east end of Dawson Ridge about 8.5 kilometres south of the town of Alice Arm. This occurrence was explored for molybdenum in the mid 1960s.

The region is underlain by Eocene Coast Plutonic Complex rocks intruding Middle Jurassic to Upper Cretaceous Bowser Lake Group argillite, shale, siltstone, greywacke and conglomerate. These sediments have been folded and altered to biotite hornfels.

The area of the showing is underlain by medium grained quartz diorite, younger leucocratic and locally porphyritic quartz monzonite and northeast striking, fine grained andesitic dikes. Narrow alaskite and pegmatite dikes cut the quartz diorite and quartz monzonite. All these rocks are intruded by lamprophyre dikes.

The showing comprises scattered molybdenite rosettes in east trending, 13 centimetre wide veins of alaskite and drusy quartz. This showing occurs in a south-facing slope, 610 metres southeast of a small lake on the east end of Dawson Ridge. Molybdenite is contained in 3 centimetre wide lenses of alaskite 120 metres to the west.
