The Hydropit is a zinc, lead, and copper 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 = Occurrence first found by the USGS in the late 70's in a quarry excavated for road metal. To 1996, no obvious signs or published descriptions of other work at the site.
Comment (Geology): Age = Tertiary or younger.
Comment (Deposit): Model Name = Polymetallic vein along shear zone (Cox and Singer, 1986; model 22c)
Comment (Geology): Geologic Description = The country rock is a Tertiary alkalic granite well exposed in a rock quarry; the intrusive is cut by sperulitic felsic dikes which are in turn cut by andesite dikes (Brew, 1997 [OF 97-156-E]).? the mineralization consists of quartz veinlets and lenses an inch or so thick in an altered shear zone about 4 feet wide that cuts the granite. The quartz vein material contains a few percent of ore minerals including chalcopyrite, bornite, galena, sphalerite, arsenopyrite, and magnetite. On analysis, selected high-grade grab sample show major Pb, Zn, and Cu consistent with the hand-specimen mineralogy, less than 0.005 ppm Au, up to 50 ppm Ag, up to 15 ppm Sn, and up to 3 ppm W. The exposure of the vein is small but could indicate more vein-type mineralization in the area.
Comment (Production): Production Notes = None
Comment (Exploration): Status = Probably inactive
Comment (Reference): Primary Reference = Grybeck, Berg, and Karl, 1984
Comment (Reserve-Resource): Reserves = None
