Capsule Geology

The TR (Sericite Schist) occurrence is located near the western margin of Treaty Glacier and occurs in rock of the Lower Jurassic Unuk River Formation, Hazelton Group. Rocks in the area include weak to moderately altered crystal-lithic andesite tuffs, intensely altered crystal-lithic andesite tuffs (sericite schist), dolomite, limestone, quartzite, pillow lavas, red, purple, green, volcanic breccias, porphyritic flows and minor chert. The strata are intruded by a Jurassic diorite stock.

The north-south trending "Sericite Schist" zone is part of a large area of alteration extending over 900 metres with a minimum width of 150 metres. Alteration includes sericite, quartz and pyrite.

A limonitic, silicified, leached andesitic tuff showing weak sericite schist alteration contained 23.7 grams per tonne gold and 5.38 grams per tonne silver over 2 metres (Assessment Report 16839).
