This volume is a compilation of two types of data: placer mining inspection reports and placer exploration assessment reports. Mining inspection reports were compiled from site visits conducted by the Placer Mining Inspection Unit from 1985 to 1988.
Assessment report summaries were written from placer assessment reports which were submitted for assessment credit. These placer exploration assessment reports were submitted to the Exploration and Geological Services Division between 1975 and 1988 and contain geological, geochemical or geophysical data which has not been previously published.
