Correct for the company name. The photo shows teh photographer was Stuart Liebman of No. Hollywood, CA.
The first research I found indicated Colorado's Copper Mountain, Then I found at least 7 more Copper Mountains in Canada and the USA. My biggest problem in location for the mine was that Breckenridge, Leadville and Frisco were all around Copper Mtn. but no mine trackage shown to any of these places. Calif. did not show a "Mountain Copper' or Copper Mountain. While the rails in the Copper Mtn. area looked good for a possible mine, the Ski lodge on the mount kept getting in the way of any mining info. Thanks for setting the proper location. I now can label to photo for recording at DeGolyer Library.
