Fairview

The Fairview 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 = Martin and others, 1915

Comment (Deposit): Model Name = Cyprus massive sulfide (Cox and Singer, 1986; model 24a).

Comment (Geology): Geologic Description = Tysdal and Case (1979) described the bedrock geology in this area as Cretaceous, pale to dark green, aphanitic to porphyritic pillow basalt with subordinate pillow breccia, tuff, and siltstone. ? the mineralization is hosted in a breccia that is fractured and recemented with quartz and sulfides, the breccia cement is soft and weathers to a gossen, although the sulfides are not evenly distributed through the cement. One zone 6 foot wide is particularly rich in sulfides. A sample of this material assayed 9.8% copper (Martin and others, 1915).

Comment (Workings): Workings / Exploration = One short, 10 foot adit was driven prior to 1918. The adit was driven in a 6 foot wide breccia zone where the cement was rich in sulfides. A sample of this richly mineralized zone assayed 9.8% Cu (Martin and others, 1915).

Comment (Exploration): Status = Inactive

Comment (Reserve-Resource): Reserves = No information available.

Comment (Geology): Age = Cretaceous.
