The Columbine Mine is a copper mine located in Albany county, Wyoming at an elevation of 8,901 feet.
About the MRDS Data:
All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.
Mine Description
In the late 1920's a drift was driven parallel to schistosity and cataclastic foliation into biotite-hornblende schist and submylonite about 200 feet above Middle Fork. Iron stained shear planes and finely disseminated sulphides in submylonite were observed but only copper and iron were reported in assays from dump material (NRRI, Table 1). Questionable quantities of platinum metals and gold have been reported from shattered vein material a few hundred feet below the portal (E. K. Burhans, 1961, personal files).

Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.
