註釋The Slate Islands are located in the northeast corner of Lake Superior within the Wawa subprovince of the Superior Province. The islands were field mapped between May 23 and August 15, 1974 and all quartz veins were sampled and checked for their gold content. All sulphide showings were sampled and submitted for emission spectrographic analysis. Sediment samples were obtained from all streams flowing into the lake or encountered on traversing and checked for their heavy metal content. This report describes the general geology, metamorphism and petrochemistry, structural geology, and mineral exploration and deposits of asbestos, copper, iron, sulphides and gold.
