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

The Liberty Gem mine is 8.5 miles southwest of Hailey, and about one-half a mile northeast of the junction of Kelly Gulch and Croy Creek. The property comprises 22 unpatented claims, owned by the National Milling and Mining Corporation. There are several exploration workings on the property, but development has been principally by two shafts; the Bernie, 230 feet deep; and the Main shaft, 210 feet deep. Both shafts are now caved at the surface. The deposits were discovered in 1927 by Newton Mathews and have been worked intermittently since that time.

Three veins are reported to occur on the property, although only one was examined. This vein is exposed in an open pit a few feet from the Main shaft. It is 30 inches thick, strikes N. 15° W. and dips 48° SW. The vein is essentially a shear zone containing irregular masses of lead ore distributed throughout the fault gouge.

The country rock is part of the Wood River formation, although it is reported (13) that on the 100-foot level from the Main shaft the vein passed into granitic rock, presumably a part of the large granitic mass outcropping nearby to the southwest in the Hailey Gold Belt area.

In 1939 a shipment of crude ore from the property assayed .015 ounce of gold per ton, 18.4 ounces of silver per ton, 18.9 per cent lead, and 3.3 per cent zinc. The production record of the mine was not obtained but it is believed to be small.

Land Status

Land ownership: BLM Administrative Area
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.
