Comments on the geologic information

  • 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.
  • 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).

Commodity type Metallic

Comments on exploration

  • Status = Inactive

Mining district

District name Juneau (Skagway subdistrict)

Comments on the reserve resource information

  • 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).

Comments on the workings information

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