Civil War Era Copper Fissure Mine in Keweenaw Co., MI

No major mining activity has occurred in this mine for over 160 years. Only the top level is accessible, and even parts of that are flooded. The main shaft is flooded, as well as a winze. Unfortunately, there is evidence of white nose in the bat population (photo 4).

Abandoned 110 year old gold mine in Clear Creek County, Colorado

High elevation gold mine, with one intact entrance and 2 or 3 levels. The top level is dry, and a winze goes down to a lower level which is flooded completely. Small mine, maybe 200 yards of intact workings.

Michigan Copper Mine

The upper 2 stopes are dry for about 1/2 mile from the entrance. Active bat habitat, and seams of residual copper are easy to come by.
