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.

Mine Info

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 (Environmental Factors): THE PRINICIPAL SOURCES OF ACID MINE DRAINAGE (AMD) IN THE AREA HAVE BEEN IDENTIFIED AS THE UNDERGROUND WORKINGS OF THE MAMMOTH MINE (INCLUDES THE FRIDAY-LOUDEN, MAIN MAMMOTH, GOSSAN, AND 300 ADITS), THE GOLINSKY MINE, AND THE SUTRO MINE. A SECONDARY SOURCE OF AMD IS SURFACE RUNOFF THAT PASSES THROUGH WASTE ROCK DUMPS, TAILINGS PILES, AND DISTURBED AREAS. THE MAMMOTH MINE HAS BEEN ESTIMATED TO CONTRIBUTE BETWEEN 87 AND 92 PERCENT OF THE TOTAL METALS DISCHARGED TO RECEIVING WATERS IN THE AREA. ABOUT 300 TO 400 GALLONS PER MINUTE (GPM), AND UP TO 900 GPM FOR SHORT PERIODS DURING WINTER, OF AMD THAT CONTAINS DISSOLVED HEAVY METALS (NBOTABLY IRON, COPPER, IRON, ZINC, AND CADMIUM) ARE DISCHARGED FROM THE MAMMOTH COMPLEX INTO LITTLE BACKBONE CREEK AND SHOEMAKER BULCH. THE MOST ACIDIC WATERS DISCHARGING FROM THE MINE HAVE A PH OF 2.2.
