註釋Describes and presents results of a project of Quaternary geologic mapping and regional humus and till sampling in the eastern part of the Shebandowan greenstone belt north-west of Thunder Bay, Ontario. The mapping helped characterize the surficial materials present within the study area and enabled reconstruction of the ice flow history associated with these deposits. The sampling program provided information on the background concentrations of various elements in humus and till as well as on the number and character of gold grains and base metal indicator minerals present in till. Anomalies are identified which define a number of exploration targets requiring further investigation.
