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 (Geology): Geologic Description = Subeconomic concentration of small particles of gold in lower course of Midas Creek. Gravel in upper course of Midas Creek is not auriferous (Degenhart and others, 1978, p. 377-379).
Comment (Deposit): Model Name = Stream placer
Comment (Deposit): Other Comments = Located within Gates of the Arctic National Park.
Comment (Reference): Primary Reference = Degenhart and others, 1978
Comment (Reserve-Resource): Reserves = No significant production or potential (Degenhart and others 1978).
Comment (Workings): Workings / Exploration = U.S. Bureau of Mines sampling program ( Degenhart and others, 1978, p. 378, 381-382, and fig. 20) showed the following: Sample BM 668: piece of quartz in stream float contained 7.2 ppm Ag and 145 ppb Au. No bedrock source found; Sample BM 677: stream silt sample contained 510 ppb Au; Sample BM 678: stream silt sample contained 50 ppb Au.
Comment (Exploration): Status = Inactive
