The Hillside 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 (Geology):
Comment (Exploration): Status = Inactive
Comment (Geology):
Comment (Workings): Workings / Exploration = The Hillside occurrence was discovered by WGM Inc. and Patino Ltd. during exploration for base metals in the 'Reef Ridge district' (Schmidt, 1997). Grab samples from surface exploration contain from 0.22 to 2.40 percent lead with up to 2,200 ppm zinc in a 100 feet by 50 feet (30 m by 15 m) area (Schmidt, 1997).
Comment (Deposit): Model Name = Southeast Missouri Pb-Zn (Cox and Singer, 1986; model no. 32a) or Mississippi Valley Type
Comment (Reference): Primary Reference = Schmidt, 1997
Comment (Commodity): Ore Material = iron-rich gossan
Comment (Deposit): Other Comments = See Beaver (MD048), Big Gate (MD050), and Bermuda (MD045) Mississippi Valley Type showings.
