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 (Deposit): THIS SITE NAME WAS CREATED BY THE REPORTER OR OTHER USGS EMPLOYEE BASED ON PROXIMITY TO SOME MAJOR GEOGRAPHIC FEATURE.
Comment (Deposit): BAR DEPOSITS ARE CONDUCIVE TO LARGE SCALE PLACER MINING METHODS; GOLD HAS ALSO BEEN REPORTED IN STREAM AND BENCH PLACERS ON LAKE CREEK, WHICH RUNS PARALLEL TO KAHILTNA RIVER ON ITS W SIDE ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT
Comment (Location): LOCATION GIVEN IS APPROXIMATE SITE OF SHOLAN BAR; OTHER SITES OF MINING ACTIVITY WERE ROUND BEND BAR AND RED HILL BAR NEAR THE MOUTH OF BEAVER CREEK. LAND STATUS VALUE CALCULATED 6-94 USING GIS OVERLAY ANALYSIS WITH BLM 1:2,500,000 SCALE OWNERSHIP STATUS MAP (1991).
Comment (Commodity): PT RECOVERED AS BYPRODUCT OF PLACER GOLD MINING; PT FOUND IN GRAINS UP TO 1/8 IN IN DIAMETER
Comment (Production): ROUND BEND BAR PRODUCED ABOUT 72.5 OZ FROM 100 CY OF GRAVEL IN 1908, (REPORTED AS 1500 DOLLARS IN GOLD WITH GOLD AT 20.67/OZ), IN USGS BULL 692, P. 263
Comment (Development): HAS BEEN MINED ON SMALL SCALE INTERMITTENTLY ALONG BARS AND BENCHES; AT LEAST 20 DRILL HOLES SUNK IN 1917
Comment (Deposit): STREAM GRAVELS 6 TO 9 FT DEEP, SEVERAL HUNDRED YD WIDE, CONTAIN GOLD, PLATINUM AND THORIUM BEARING MINERALS
