Capsule Geology

This showing occurs along Sulphurets Creek about 2 kilometres west of the toe of Mitchell Glacier. The area is underlain by rock of the Lower Jurassic Unuk River Formation, Hazelton Group. Rocks are reported to consist of a green-grey lapilli tuff, grey tuff and an intervening package of undifferentiated sediments. The sediments and grey tuff are the most intensely altered. The sediments are characterized by intense silicification, sericitization, pyritization, and jarosite staining.

Northeast trending quartz veins occur primarily within the altered sediments. These veins contain pyrite with minor amounts of chalcopyrite, tetrahedrite or molybdenite. Samples assay up to 3.09 grams per tonne gold (Assessment Report 15688).
