Location: This prospect is on the southeast side of Molybdenum Mountain at an elevation of about 800 feet, upslope of the Owhat River. The map site is in the SE/4 sec. 21, T. 20 N., R. 55 W., of the Seward Meridian. It is approximately located, perhaps within one-half mile. This is locality 4 of Hoare and Cobb (1972, 1977). Hoare and Coonrad (1959) showed a prospect symbol at this location.
Geology: Float specimens from this location contained molybdenite and powellite (?) in quartz (Smith, 1942). Hoare and Coonrad (1959) show a prospect symbol in a granitic stock at this location. The granitic stock may be part of a Cretaceous or Tertiary igneous assemblage that is widespread through southwest Alaska. The country rocks to the stock are clastic sedimentary rocks that may be part of the mid-Cretaceous Kuskokwim Group (Hoare and Coonrad, 1959) or possibly an older Paleozoic or Mesozoic section correlative with the Gemuk Group (Bundtzen and Laird, 1991).
