Capsule Geology

The Bradley vein on the Comstock property is hosted in volcanics and sediments of the Mississippian to Jurassic Bridge River Complex (Group). The vein is in mostly greenstones but extends into argillites a few hundred metres to the east. The 1.2-metre vein strikes west-northwest with a steep north dip and is composed of 15- centimetre bands of quartz on either wall enclosing a calcareous infilling. Abundant pyrite with lesser amounts of arsenopyrite form a banded structure. Surface assays yield 0.68 grams per tonne gold and deeper samples gave 12.34 grams per tonne gold (Geological Survey of Canada Memoir 213, page 101). The vein was explored by a 10-metre shaft.
