Principal Minerals

Contained within the 3rd Edition (1957) of the Atlas of Canada is a plate that shows 20 different maps of principal minerals across Canada, circa 1955. The maps were compiled from information supplied by the Mines Branch of the Department of Mines and Technical Surveys. Usually, the principal occurrences have been indicated but where these are very numerous only the areas in commercial production are shown. It should, therefore, be noted that not all of the principal occurrences are actually mined.
