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 (Development): SPORADIC MINING FROM 1907 TO 1940'S. NO SIGN OF ACTIVITY IN 1975-77.
Comment (Deposit): GOLD AND CASSITERITE REPORTED TO BE DISTRIBUTED VERTICALLY THROUGH GRAVEL OF PAYSTREAK. GROUND NEAR HEAD OF CREEK IS 15 TO 20 FT. DEEP, INCLUDING 1-15 FT. OF GRAVEL BENEATH MUCK. PLACERS HAVE NOT BEEN EXTENSIVELY OR SYSTEMATICALLY PROSPECTED; PAYSTREAK INFERED TO BE 30 FT. WIDE, 1-15 FT. THICK, AND TO EXTEND POSSIBLY AS MUCH AS 5,000 FT. DOWNSTREAM FROM THE MOUTH OF COX PUP. COLORS OF GOLD IN ALL 15 PROSPECT HOLES; CONSIDERABLE PYRITE FOUND IN ALL THESE HOLES, PYRITE IN GRAVEL OR ATTACHED TO LARGE FRAGMENTS OF BEDROCK.
Comment (Workings): 15 HOLES SUNK 15 TO 60 FEET TO SLATY BEDROCK. MOST OF GROUND IS NOT FROZEN AND DIFFICULT TO WORK BY DRIFT MINING.
Comment (Geology): NO KNOWN CONTACT BETWEEN SLATY BEDROCK AND GRANITE IN VALLEY, BUT FRAGMENTS OF VEIN QUARTZ WITH TOURMALINE PRESENT. ; MAJOR.UNITS: BEDROCK IS SLATE. ; REG.COM: GOLD AND CASSITERITE APPARENTLY CLOSE TO THEIR SOURCE.
Comment (Deposit): STREAM GRADIENT APPROXIMATELY 82 FT. PER MILE. BIG CREEK FLOWS IN A WIDE, SHALLOW VALLEY WITH VERY GENTLY SLOPING SIDES. THE VALLEY IS ABOUT 1.5 MILES WIDE BETWEEN THE DIVIDES, AND THE FLOOR IS APPROXIMATELY 300 FT. WIDE. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT
