Unnamed (lower Slate Creek)

The Unnamed (lower Slate Creek) is a mercury 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 = Reconnaissance surface observation and geochemical sampling has occurred at this site.

Comment (Commodity): Gangue = Carbonate

Comment (Geology): Age = Not known. Postdates or accompanies deformation of the mid-Cretaceous Kuskokwim Group along the Golden Gate fault.

Comment (Reference): Primary Reference = Frost, 1990

Comment (Deposit): Model Name = Silica-carbonate Hg (Cox and Singer, 1986; model 27c).

Comment (Geology): Geologic Description = Frost (1990) reported that discontinuous lenses of silica-carbonate rock are present along the Golden Gate fault near where it crosses Slate Creek, an east tributary to the Tuluksak River (Box and others, 1993). Quartz and several generations of carbonate viens, in many cases enclosing relict fragments of serpentinite, make up the silica-carbonate rock. Samples from this locality (Frost, 1990, table 1, locality 5) contain 1.9 to more than 36 ppm Hg.

Comment (Exploration): Status = Inactive
