Unnamed (Sledge Creek)

The Unnamed (Sledge Creek) is a gold 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 = The veins were explored by shallow pits, some of which were excavated before Cathcart's visit in 1920.

Comment (Deposit): Model Name = Low-sulfide Au-quartz vein? (Cox and Singer, 1986; model 36a).

Comment (Geology): Age = Mid-Cretaceous or younger; cross cuts metamorphic rocks of that age.

Comment (Exploration): Status = Inactive

Comment (Reference): Primary Reference = Cathcart, 1922

Comment (Geology): Geologic Description = Quartz-feldspar veins crop out south of Sledge Creek just upstream of where Sledge Creek enters onto the Snake River valley and about 700 feet upslope from a water ditch. This occurrence appears to be similar to a quartz-feldspar vein described by Cathcart on the north side of Sledge Creek (Cathcart, 1922, p. 249, figure 19, location 2), who also identified feldspar at the occurrence on the north side of Sledge Creek as orthoclase, probably because of its nearly euhedral platy form. The feldspar is probably albite or a sodic oligoclase similar to the platy feldspar found abundantly at the Alpha Ridge prospect (NM171) about a half mile south of this occurrence. Sulfides were not observed by Cathcart, but the vein was iron-stained. Similar nearby quartz-feldspar veins are gold bearing.
