Capsule Geology

The Toe showing is located at the toe of Mitchell Glacier on the north side of Mitchell Creek. The area is underlain primarily by intermediate to mafic pyroclastics and flows of the Lower Jurassic Unuk River Formation, Hazelton Group. A stock of Jurassic monzonite to quartz monzonite intrudes immediately north of the toe. Rocks in the area have undergone pervasive pyrite-quartz-sericite alteration (Open File 1988-4).

The occurrence is reported to consist of quartz veins containing galena, sphalerite, molybdenite and tetrahedrite (Personal Communi- cation, J.M. Britton). Massive chalcopyrite in veinlets was also observed just north of the toe (Bridge et al, 1981).
