The Quinsam coal measures and adjacent terrane described in this report underlie an area of about 130 square kilometres west and southwest of Campbell River on Vancouver Island. Figure 1 shows the location and the principal features of the surrounding area.
The area is more or less centred on the northwest end of the belt of coal-bearing Upper Cretaceous rocks. The original purpose of this study was an assessment of the coal potential; however, in outlining the extent of the coal measures, identification and correlation problems arose with the surrounding older rocks, and the mapping was necessarily extended. It was further extended northwest to Strathcona Dam to locate more accurately the north contact of the Quinsam stock and to show, in reconnaissance fashion, the occurrence of pyritic rocks containing minor amounts of copper and southwest to include known mineral showings west of Gentian Lake.
