Capsule Geology

Lower Jurassic Hazelton Group volcanics and sediments of the Unuk Formation, located on the east side of Harrymel Creek are in fault contact with the Upper Triassic Stuhini Group sediments to the west. The contact between the Triassic and Lower Jurassic rocks is marked by an extensive north-northwest trending cataclasite zone, known as the South Unuk Zone, which contains biotite-chlorite-epidote schist (Bulletin 63, Figure 13).

Mineralization occurs within schists in this cataclasite zone along the west side of Harrymel Creek, near a north trending fault. Pyrrhotite and chalcopyrite occur within a gossanous zone in epidotized greywacke and epidote bands within the schist. To the west of this showing epidotized limestone and silicified schists are in con- tact with sheared and epidotized greywacke and argillite which are part of the Stuhini Group sediments.

On the east side of the fault and cataclasite zone, the Hazelton Group, Unuk Formation rocks consist of graphitic schists, greenstone, andesite and felsite.

Recent work, along a shear zone separating Upper Triassic volcanics from argillaceous and graphitic sediments, indicates that the mineralization occurring within this zone consists of pyrite, galena, sphalerite, chalcopyrite and locally, silver sulphides. The silver minerals are localized in silicified areas in the footwall of the shear and samples have assayed in excess of 13,000 grams per tonne silver (Equity Preservation Corp., 1988).
