The Deimos 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 (Reference): Primary Reference = Newberry and others, 1986
Comment (Workings): Workings / Exploration = Surface sampling.
Comment (Deposit): Model Name = Cu skarn deposits (Cox and Singer, 1986; 18b)
Comment (Deposit): Other Comments = See also: Io (CH102), Ginger (CH060), Hurricane-Diane (CH062), Venus (CH065), Pilgrim (CH099), Mike (CH100), Vicki (CH097), Cindy (CH098), and Evelyn Lee (CH059).
Comment (Exploration): Status = Not determined
Comment (Geology): Age = Devonian based on reported Early Devonian Pb/Pb zircon ages from the associated Baby Creek batholith and Horace Mountain plutons (Dillon and others, 1996).
Comment (Geology): Geologic Description = The Deimos prospect is one of a number of skarn deposits in the Chandalar area which have been described in general by Newberry and others (1986). These skarns are all northwest of a belt of Devonian(?) granitic rocks informally named the Horace Mountain plutons. Many exhibit both prograde and retrograde mineral assemblages. Newberry and others (1986) stated that their mineralogy, mineralization, and alteration place them in the category of continental-margin, porphyry-related copper skarns. Published information about the geology of individual skarns is scarce, but brief descriptions of the prospect by Newberry and others (1986) indicated that the Deimos prospect is a Cu-Ag skarn. Based on a hand specimen description (Newberry and others, 1986), the skarn contains garnet, epidote, chalcopyrite, and pyrite. Analysis of the hand specimen returned a value of 1.9 percent Cu. In a listing posted on the Ventures Resource Corporation (currently exploring Doyon lands in the area under an agreement with Doyon, Limited) website (URL http://www.venturesresource.com/), the Deimos prospect is classified as a Cu-Au prospect, although there are no data supporting the presence of appreciable gold.
