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.

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.
Some gold has been produced in the Ubehebe copper-lead-silver district. The district is in central Inyo County about 75 miles east of Lone Pine. The chief source of gold has been the Lost Burro mine, which was worked from 1906 to 1917 and 1934 to 1942. The value of its total output is about $100,000. The gold occurs in a flat four-foot-thick vein of quartz, jasper, and calcite that is near a contact between limestone and granitic rocks. The gold occurs in the native state with pyrite and chalcopyrite.

Land ownership: National Park
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.
