The Unnamed 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 = Brief reconnaissance geologic mapping and collection of a few soil and silt samples reported by Christie (1974). Gold, silver, zinc, copper, and molybdenum were at background levels.
Comment (Reference): Primary Reference = Christie, 1974
Comment (Geology): Geologic Description = Christie (1974) described a color anomaly and associated gossan developed in hornfelsed andesite and dacite east of a contact with a fresh, medium-grained, unpyritized quartz diorite pluton. Gossan forms an oval, roughly 2,000 by 1,200 ft (1,500 by 900 m), but it is not fully delineated. Within the color anomaly, there are several thin breccia zones which are highly leached. Color anomaly is due to the weathering of pyrite, which is disseminated or localized in fractures in concentrations up to 8 percent. Northwest of the gossan, very recent volcanic debris and young flows from Mt. Dutton cover a hidden gossan as evidenced by bright orange seeps and strong iron-oxide staining in creek.
Comment (Deposit): Model Name = Epithermal gold vein
Comment (Deposit): Other Comments = Sampling probably not adequate to evaluate for epithermal gold vein mineralization.
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Pliocene or younger
