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.

Comments

Comment (Deposit): "Deposit" includes the Nacimiento, Eureka, and San Miguel Mines as well as smaller "mines". Reserves are for the Nacimiento Mine, the largest of the mines in the district. Production is not reported for the individual mines.

Comment (Reserve-Resource): Reserves are reported only for the Nacimiento Mine, not for the entire district/deposit. As of May 2, 1980 (McLemore and Hoffman, 2005, p. 450) reserves are 5.4 million metric tons at 0.56% Cu and an additional 11.8 million mt at 0.48%. As of 1969, reserves at the Nacimiento Mine were estimated to be 9.6 million tons (short tons?) at 0.71% Cu (Woodward and others, 1974, p. 108)

Comment (Production): Production for the entire district is 27,704 short tons ore containing 75,297 oz Ag, and 7,582,410 lbs Cu (McLemore and Hoffman, 2005, p. 451)
