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

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.
