The Cliff Mine is a gold and silver mine located in Albany county, Wyoming at an elevation of 8,999 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
A 775 foot drift was driven northeastward in part along a 2-3 inch thick quartz vein that parallels schistosity and cataclastic foliation of the enclosing mafic schists and submylonites. According to Hess (1926, p. 132) "neither gold nor platinum was reported in this drift." A 325 crosscut extending to the northwest from near the end of the main drift cuts four quartz and sulphide bearing fracture zones, at least one of which supposedly contained gold. Traces of platinum were reported from a short drift paralleling one of the fracture zones (Hess, 1926, p. 132).

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.
