Historically, the discovery of a gold deposit was always foremost in the mind of the prospector. In 1869 an Indian prospector, Moses Pe-Kong-Gay, found evidence of gold near the present town of Heron Bay on Lake Superior in Ontario. While shafts were soon sunk and some ore shipped, little of significance occurred during the next 70 years.
