The copper deposits of the Encampment District, Wyoming

During the last few years prospecting in the Medicine Bow and Park ranges in northern Colorado and southern Wyoming has proved that copper-bearing minerals occur frequently and are very generally distributed over a wide region in this portion of the Rocky Mountains. This has gradually become known through the discovery of several more or less promising copper deposits and also through the exploitation of a few properties which have produced ore on a commercial scale. The increase in the number of prospectors has kept pace with the increasing interest in the region, until now every part of it has been at least cursorily examined. In spite of this activity and of a considerable amount of development work at several localities, the productive mines in actual operation are few, but the search for valuable deposits continues, and it is to be expected that other mines will eventually be discovered.
