0416 Range of Opportunity

The Copper Range, along with the Quincy Mining Co. and the Calumet-Hecla Mining Co. dominated the Lake Superior copper mining industry. Operating initially on the Baltic lode, Copper Range survived the rapid decline of the area in the 1920s and the Great Depression to find a new lease on life by shifting in the 1950s away from native copper to the copper chalcolite of its White Pine operations. This book is the first significant look at the history of this important mining company.
