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.
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 (Location): USGS MF-410, LOC. 18. DEPOSIT ON RIDGE BETWEEN EVA AND ST. PATRICK CREEKS ON THE SE SIDE OF ESTER DOME. MINE MARKED ALONG ESTER DOME RD. ON FAIRBANKS (D-2). LAND STATUS VALUE CALCULATED 6-94 USING GIS OVERLAY ANALYSIS WITH BLM 1:2,500,000 SCALE OWNERSHIP STATUS MAP (1991).
Comment (Development): CLAIMS PATENTED IN 1914. EXTENSIVE UNDERGROUND WORKINGS (NEARLY A MILE) AND TRENCHING, BUT NOT MUCH ORE MINED AND MILLED.
Comment (Deposit): MINERALIZED FAULT ZONE CONTAINS SHEARED SCHIST AND QUARTZ VEINS IN A LODE 40-70 FT. WIDE. METALIC MINERALS ARE GOLD, ARSENOPYRITE, AND STIBNITE. MOST OF METAL CONTENT IS IN ZONE OF QUARTZ 9-20 FT WIDE NEAR THE HANGING WALL SIDE OF LODE. LENSES OF STIBNITE HAVE BEEN FOUND.
Comment (Workings): IN 1916-17 ABOUT 500 FT. OF SHAFT AND WINZE AND 970 FT. OF DRIFTS AND CROSSCUTS; THROUGH SAMPLING. ADDITIONAL EXPLORATION AND DEVELOPMENT, 1917-30, INCLUDED A 65 FT. SHAFT AND A CROSSCUT. 1938-42 SAW MORE THAN 1,500 FT. OF SHAFTS, 2,000 FT. OF DRIFTS, ADITS, AND CROSSCUTS, AND MORE THAN 2,800 FT. OF TRENCHES. MINOR TRENCHING AND DRILLING, 1954-58.
Comment (Geology): FAULT ZONE OF CRUSHED SCHIST AND QUARTZ VEINS IS HANGING WALL OF MAJOR SHEAR ZONE 750-1,500 FT. WIDE. FAULT MOVEMENT WAS MAINLY POST MINERALIZATION.
Comment (Deposit): USBM DRILLING PROGRAM IN 1969-70 WAS A PILOT STUDY TO COMPARE ROTARY DRILLING AND BULLDOZER TRENCHING FROM COST AND ENVIRONMENTAL DAMAGE POINTS OF VIEW AND WAS NOT INTENDED TO RESULT IN NEW KNOWLEDGE ABOUT THE DEPOSIT. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT
