On the summit between Myra and Phillips creeks, east of a body of Early to Middle Jurassic Island Plutonic Suite granodiorite, irregular remnants of Permian to Pennsylvanian Buttle Lake Group limestone (Azure Lake Formation) contains small lenses and veins of chalcopyrite and pyrite. The showing is assumed to be skarn related.
The interpretation of the geology of the Buttle Lake Uplift, in which this showing occurs, is presently undergoing revision. Please refer to occurrence 092F 120 for a summary of this revision.
