Haines Iron

The Haines Iron is a titanium and iron 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 = Robertson, 1956

Comment (Exploration): Status = Inactive

Comment (Geology): Age = Probably Cretaceous based on Still and others' (1991) correlation of the Haines mafic-ultramafic complex with the Cretaceous, Klukwan mafic-ultramafic complex (SK030) to the north (MacKevett and others, 1974).

Comment (Geology): Geologic Description = This prospect occurs within what Still and others (1991) call the Haines mafic-ultramafic complex. They believe this complex to be of similar character and the same age as the Cretaceous, Klukwan mafic-ultramafic complex (SK030) (MacKevett and others,1974). Knopf (1910) describes this prospect as pyroxenite that contains magnetite intergrown with ilmenite in grains as much as 0.25 in diameter. The pyroxenite is in contact with epidote diorite and metabasalt. He estimates the resource at several billion tons of material containing less than 10% magnetite.

Comment (Deposit): Model Name = Disseminated magnetite and ilmenite in a pyroxenite (Cox and Singer, 1986; model 9).

Comment (Workings): Workings / Exploration = A 100-foot tunnel that was driven in 1906 is now caved (Robertson, 1956).

Comment (Reserve-Resource): Reserves = 'Widely spaced dip needle traverses and sampling along the shore and in roadcuts in the early 1950's indicated that the Haines deposits contained several billion tons of low-grade magnetite-bearing pyroxenite. Data are inadequate to estimate the grade, but the magnetic iron content seems to be less than 10%' (Berg and Cobb, 1967).
