The Eva Creek Placer is a gold mine located in Alaska.
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 (Deposit): GRAVELS IN UPPER 1.5 MILES OF CREEK OVERLYING SCHIST ARE AURIFEROUS. GRAVELS OVERLYING NENANA GRAVEL UP TO 1/2 MI. DOWNSTREAM OF SCHIST AREA CARRY GOLD. FLOAT NEAR LIBERTY BELL MINE CONTAINS GOLD, BISMUTH, AND ARSENOPYRITE. SCARCE PLACER SCHEELITE.
Comment (Location): USGS MF-410, LOC. 65. PLACER DEPOSITS IN HEADWATER SECTION OF EVA CREEK NEAR AND DOWNSTREAM OF LIBERTY BELL MINE MARKED ON FAIRBANKS (D-2). COORDINATES GIVEN FOR APPROXIMATE CENTER OF PLACER GROUND. LAND STATUS VALUE CALCULATED 6-94 USING GIS OVERLAY ANALYSIS WITH BLM 1:2,500,000 SCALE OWNERSHIP STATUS MAP (1991).
Comment (Development): MINING REPORTED IN 1915, 1916, 1920-21, 1933-38, AND 1940. OPEN-CUT METHODS REPORTED. AUTOMATIC DAM BUILT IN 1916 ON CUT ABOUT 1/4 MI. ABOVE MOUTH OF WILSON CR.
Comment (Geology): SCHIST IN HEADWATER SECTION OF CREEK EXPOSED BY RECENT EROSION OF OVERLYING GRAVELS. ; MAJOR.UNITS: BEDROCK FOR THE UPPER 1.5 MILES OF CREEK IS SCHIST; LOWER 3.5 MILES CUT IN NENANA GRAVEL. TRANSITION FROM SCHIST TO GRAVEL BEDROCK ABOUT 1/4-1/2 MILE ABOVE THE MOUTH OF WILSON CREEK. ; REG.COM: GOLD PROBABLY DERIVED FROM LIBERTY BELL AND SIMILAR LODES. THE FACT THAT NO NOTABLE CONCENTRATIONS OF PLACER GOLD HAVE BEEN FOUND DOWNSTREAM OF WILSON CR. CONFLUENCE, POINTS TO THE CONCLUSION THAT OLD GRAVELS CARRY VERY LITTLE IF ANY GOLD.
Comment (Deposit): STREAM GRADIENT ABOUT 200 FT. PER MILE. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT
