The Shirley Lake is a uranium 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 (Reference): Primary Reference = Freeman, 1963
Comment (Reserve-Resource): Reserves = All deposits appear to be small and low grade (Cobb, 1979, OF 80-86, p. 22).
Comment (Workings): Workings / Exploration = Shallow pits were excavated and scintillometer surveys conducted.
Comment (Commodity): Ore Material = Unidentified secondary uranium minerals
Comment (Deposit): Other Comments = the area prospected in the Long Lake Hills around Shirley Lake extends into the Talkeetna Quadrangle to the north.
Comment (Geology): Geologic Description = Secondary uranium minerals sporadically localized along joints in Tertiary tuff and tuff-breccia (Cobb, 1979, OFR 80-86, p. 22; Reed and others,1978; and Reed and Nelson,1980). Radioactive rock probably formed by deposition of small amounts of uranium that migrated with subsurface water moving along joints. Exploration did not disclose any extension of radioactive rock below surface or away from joints. Maximum amount of radioactivity in USGS samples was 0.021% uranium; prospector reported assay of 0.29% uranium in one sample (Freeman,1963, p. 29-30). The area prspected in the Long Lake Hills around Shirley Lake, extends into the Talkeetna Quadrangle to the north.
Comment (Exploration): Status = Probably inactive
