Comments on the geologic information

  • Geologic Description = Thin lens and pods of chromite within in a klippe of the informally named Border Ranges mafic and ultramafic complex of Burns (1985). Overall the klippe is about 2 square miles in size and is composed of mostly of hartzbergites and pyroxenites with minor amounts of dunite (Bill Ellis, personal communication, 1999). Chromite is found within the dunite layers as thin layers, lens and pods.
  • Age = Jurassic.

Economic information about the deposit and operations

Development status Occurrence
Commodity type Metallic

Comments on exploration

  • Status = Inactive

Mining district

District name Homer

Comments on the workings information

  • Workings / Exploration = Anaconda minerals discovered the occurrence in 1982 as part of a regional exploration program on the Kenai Peninsula. Work included airborne geophysics, stream and soil geochemistry, minor hand trenching and rock chip samples. Selected samples assayed up to 35% chromic oxide (William Ellis, personal communcation, 1999).
