The Unnamed is a gold 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 (Geology): Geologic Description = Silicified volcanic breccia cut by 60-m-wide andesite(?) dike. Coats (1956) mapped knob as a plug, however the bulk of the outcrop along the road is breccia. Interstitial spaces between breccia fragments are locally zeolite(?) filled. Dike has a well developed chilled margin.
Comment (Workings): Workings / Exploration = A number of samples (93AWs 2a-d) were collected during brief U.S. Geological Survey reconnaissance studies in 1993; all were copper-bearing in the 110-160 ppm Cu range. A few samples of andesite and andesitic volcanic breccia yielded low-level gold in the 2-6 ppb range. Float samples were found of iron-stained andesite(?) that contained 3-5 percent unidentified sulfide minerals.
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Tertiary
