The purpose of the report is to provide a single accessible source of old and new compiled information on gold deposits in the area. The main body of the report is comprised of 120 detailed property descriptions which are comprehensive and concise summaries of information including: location, geological setting, description of mineralization, an up-to-date history of ownership and development, economic features, production data and selected references. Many of the property descriptions include new and unpublished government assay data. All properties are numerically cross-referenced to a 1:100 000 scale location map. This report will serve as a useful introduction and reference to the gold deposits in this complex and interesting greenstone belt.
