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: 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.

Comment (Location): Bailey shows Seismic Mine as a shaft west of a small road intersection on the north side of a short spur ridge running NW from Sheep Mountain. Not certain if this is the same shaft as is shown on the Jeffrey Ctiy 24k topo just 70 m to the NW.

Comment (Production): As of May, 1969 the Seismic Mine was producing about 100 tons of ore per day (Bailey, 1969, p. 114).
