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.

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
History and production: The United Eastern Mining Company was incorporated in 1913 by J. L. McIver and G. W. Long to prospect an apparent fault fissure north of the Tip Top ore body. Aided financially by W. K. Ridenour, F. A. Keith, S. W. Mudd, P. Wiseman, C. H. Palmer, Jr., and others, a shaft was sunk at the northern end of Oatman and the ground was purchased for $50,000. Ransome says: 114 "In March, 1915, a cross-cut on the 465-foot level went through 25 feet of ore that assayed $22.93. By the end of 1916, after an ore body estimated to contain gold to the value of about $6,000,000 had been blocked out, a 200-ton mill had been built and a new shaft in the hanging wall of the vein had been completed and equipped. The mill was afterward enlarged to a capacity of 300 tons."
Meanwhile, the Big Jim vein, immediately northeast of the Grey Eagle and Black Eagle claims of the Tom Reed Company, had been discovered. Ransome continues: "In April, 1917, the United Eastern Company purchased the Big Jim mine. The able mining engineers who were directing the United Eastern Company were well aware that the Big Jim and Grey Eagle veins were probably once continuous and owed their separation to faulting, but they were convinced that the amount of the throw about 400 feet, was too great to enable the Tom Reed Company to make successful claim to the Apex of their vein."
The known ore bodies of the United Eastern property were exhausted by June, 1924. Dump ore was treated in 1925, and some production was made by lessees in 1926. Considerable diamond-drill prospecting was done, particularly from the eighth and tenth levels, but without success. As shown in the table on page 82, the total yield of the United Eastern mine from 1917 to 1926, inclusive, amounted to approximately $14,853,395. The average costs per ton, according to Moore,115 amounted to $8.254 of which $4.332 was for mining.
Since late 1932, lessees, employing about thirty men, have mined approximately 50 tons of ore per day from between the 500- and 700-foot levels of the Big Jim mine. This ore was milled in the Telluride plant of the Oatman Associates Mining Company.
Ore bodies: The United Eastern main ore shoot occurred on the Tom Reed Extension claim, on the northeastern branch of the Tom Reed fracture, along which the Gold Road latite has been dropped against the Oatman andesite. In maximum dimensions. this ore shoot was 950 feet long, 750 feet high, and 48 feet wide. It nowhere outcropped at the surface as a distinct vein and was of commercial grade only between the third and ninth levels. The vein continues in depth, but only as low-grade material. The ore consisted partly of massive quartz with adularia and calcite and partly of stringers separated by barren andesite. This ore body produced 511,976 tons with an average gross value of $21.037 per ton.
The other ore body mined by this company was on the Big Jim claim. As already explained, the upper portion of this shoot had been displaced by faulting and was mined on the Grey Eagle and Bald Eagle claims. In maximum dimensions, the ore body on the Big Jim claim was 850 feet long, 450 feet high, and 35 feet wide. It produced 220,552 tons with an average gross value of $17.248 per ton.
