The Siksikpuk River is a lead and zinc 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 (Workings): Workings / Exploration = Sulfide-bearing concretions contain 1.3% Zn, more than 2,000 ppm Ba, and 52 ppm Pb. The ironstone bed contains 1,357 ppm Zn.
Comment (Exploration): Status = Inactive
Comment (Reference): Primary Reference = Kurtak and others, 1995, USBM OFR 8-95
Comment (Deposit): Model Name = Sediment-hosted Pb-Zn
Comment (Geology): Geologic Description = Red-brown concretions in Kayak Shale are confined to an approximately 6 m-thick section of black shale. They range from 4 cm rounded forms to 7.5 x 38 cm flattened, elongate forms. The concretions contain quartz, calcite, barite, siderite, and pyrite as septarian fracture fillings along with minor sphalerite and trace galena. At the base of the shale, a 10 cm-thick red-brown cherty ironstone bed contains minor sphalerite. The ironstone bed is exposed along strike for 6 m.
Comment (Geology): Age = Mississippian
