The Ferney Gulch Mine is a zinc, copper, arsenic, and silver mine located in Lincoln county, Wyoming.

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.

Mine Info

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.

Land Status

Land ownership: National Forest
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.

Comment (Development): ADITS LOCATED ON THE SOUTH SIDE OF FERNEY GULCH WERE DRIVEN IN EXCESS OF 100 FEET AND CONTAIN WINZES OF UNKNOWN DEPTH

Comment (Deposit): THE NUGGET SANDSTONE IS HIGHLY FRACTURED APPARENTLY AS A RESULT OF MOVEMENT ALONG A SMALL DISPLACEMENT FAULT WITH IT'S NORTH BLOCK DISPL ACED DOWN ; INFO.SRC : 1 PUB LIT

Comment (Deposit): THE STRATIGRAPHIC HORIZON OF MINERALIZATION IS IN THE TOP 50 FEET OF THE NUGGET SANDSTONE

Comment (Workings): "This copper and silver prospecting area consists of 5 open or partially collapsed adits, 2 open shafts, and numerous small surface pits and trenches. The site presents multiple physical hazards, particularly the open shafts, which at the time the inventory [9/1993] were almost completely unprotected. The remote location alone prevents this site from being rated a hgh potential physical hazard." (Martin, 1994, p. 31)
