The Unnamed (southwest of head of Zachary Bay) is a 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 (Exploration): Status = Inactive
Comment (Deposit): Model Name = Porphyry Cu; Porphyry Cu-Au (Cox and Singer; 1986; models 17 and 20c)
Comment (Deposit): Model Number = 17, 20c
Comment (Deposit): Other Comments = This site is located on land patented by, or interim-conveyed to, the Aleut Corporation.
Comment (Geology): Age = Tertiary.
Comment (Reference): Primary Reference = Christie, 1974
Comment (Workings): Workings / Exploration = The Aleut-Quintana-Duval joint venture examined and sampled the occurrence in 1974 (Christie, 1974).
Comment (Geology): Geologic Description = This site represents a color anomaly 1,500 by 6,000 feet (Christie, 1974, number 83), in Tertiary diorite, dacite, and hornfels (Wilson and others, 1995). Coarse clots and disseminations of pyrite occur in the diorite and dacite. Hornfels at a diorite contact contains disseminations and fracture fillings of chalcopyrite and magnetite exposed in a 200- by 200-foot area. Samples of this rock contained up to 0.3 percent copper. Christie (1974) also reported a pyritic stockwork containing 500 ppm copper. One sample of this stockwork assayed 0.06 ppm gold.
