The Unnamed (east of Sunrise 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 (Geology): Geologic Description = Hematite occurs as dark red and black veinlets and as fine botryoidal masses in cavities in brecciated and hydrothermally altered, porphyritic rhyolite, in part of a unit described as rhyolite domes, tuffs and breccia by Patton and others, 1980). Possible dark, oxidized cinnabar also occurs in the veinlets (Patton and Moll, 1983). Three samples contained 0.95 to 3.70 ppm mercury (Patton and Moll, 1983).
Comment (Workings): Workings / Exploration = Three samples contained 0.95 to 3.70 ppm mercury (Patton and Moll, 1983).
Comment (Reference): Primary Reference = King and others, 1980
