The Eye occurrence is located approximately 88 kilometres east of the community of Dease Lake.

The area is underlain by upper Mississippian to Permian Cache Creek Complex rocks including metavolcanics (greenstone), metasediments and tectonically emplaced ultramafic rocks. The Cache Creek ultramafic rocks consist of peridotite, dunite and pyroxenite which are generally serpentinized.

Scattered grains of chalcopyrite and pyrite occur over a small area within a porphyroblastic epidote schist unit. Porphyroblasts appear to be lapilli and therefore the protolith is probably a lapilli or crystal tuff.

Drilling by Westfrob Mines (Falconbridge Nickel Mines Ltd.) occurred in 1977 about 750 metres to the southeast of the above showing. The mainly chloritic metavolcanic rock encountered contained disseminated pyrite, pyrrhotite (some blebs) and occasional chalcopyrite. Mineralization at the time was not considered significant. Copper values from analyses were less than 0.03 per cent and averaged 0.01 per cent; assays for precious metals are not indicated (Assessment Report 7603). Geochemical, induced polarization, electromagnetic and magnetometer surveys were also conducted by Westfrob in 1977.
