The French attempt to mine copper on Lake Superior in 1739
1739: New Mines near Lake Superior
These two letters describe French attempts to mine copper at Ontanagon, on the south shore of Lake Superior, in the 1730's. The first, from Beauharnois, merely communicates the second and longer one, from Louis Denys La Ronde. La Ronde was a soldier, commandant at Chequamagon, and had been assigned the task of evaluating whether copper could be mined and shipped. He reports his findings here, but his project never came to fruition due to ongoing warfare between the Sioux and Ojibwa. Related documents are also in this volume of Wisconsin Historical Collections, under the date 1735.
