The Eagle showings are located in the Sutton Creek/Gordon River area, 14 Kilometres south of Caycuse. The main showing is on Sutton Creek near the Gordon River-Honeymoon Bay road. The Eagle showings occur in the southern portion of a 3 by 1 kilometre alteration zone (Malcolm, 1971).
The area is underlain by basaltic rocks of the Karmutsen Forma- tion, sedimentary rocks of the Quatsino and Parson Bay formations, all of the Upper Triassic Vancouver Group and by volcanic rocks of the Lower Jurassic Bonanaza Group. These are intruded by Early to Middle Jurassic Island Plutonic Suite rocks. A major fault trends parallel to Gordon River striking 110 to 150 degrees. Shearing is prevalent with shears striking 060 to 120 degrees. Faults in the area contain sulphides, quartz and calcite. The claims are underlain by feldspar porphyry, basalt, volcanic flows, pillow and amygdaloidal basalts, breccias, tuffs, limestone and intrusive rocks.
The occurrence comprises several showings in a northwest trending linear area originating at the main showing. The main showing consists of chalcopyrite, bornite and pyrite hosted in altered and brecciated feldspar porphyry in a shear zone closely associated with the main fault. Sphalerite and pyrite occur about 250 metres to the south in a similar setting. Silver was observed in fractures in volcanic rocks on the banks of Sutton Creek.
Copper anomalies outlined by geochemical and geophysical surveys in 1985 coincide with surface gossans. Assays from these showings were low in precious and base metals.
In 1984 through 1988, Western Forest Industries completed programs of geological mapping, prospecting, geochemical sampling and, in 1988, a ground geophysical survey on the Eagle claims.
