These townships were mapped at 1:15,840 scale during the 1987 field season, using standard pace and compass traverses using black and white vertical aerial photographs for control. The map area lies within the English River drainage basin, which is part of the Arctic watershed. The report first gives a general geology of the area, describes the geochemistry and the structure and metamorphism. The economic geology is given through a description of the various mining properties in the region and the years in which they operated.
