Geological Summary
The claims are underlain by the Upper Triassic Karmutsen Formation in fault and intrusive contact with granodiorite of the Lower-Middle Jurassic Island Intrusions. Major fault and shear directions are 112 degrees. Four showings of pyrite-chalcopyrite with trace sphalerite and galena have been found. Selected samples assay as high as 29.1 grams per tonne gold, but most average much lower. The Junction showing is a cataclastic zone along Ursus Creek.
