The locality is in the Wrangell-Saint Elias National Park and Preserve.
Location: This prospect is south of Rex Creek. It is at an elevation of about 4,700 feet, 4,500 feet north-northwest of Mount Holmes in the SW1/4 of section 26, T. 6 S., R. 16 E. of the Copper River Meridian. This is locality 55 of MacKevett (1976) and it is accurately located. The prospect is shown on the McCarthy B-4 topographic map (1994 edition).
Geology: The deposit at this prospect is at the contact of a Tertiary felsic pluton and hornfels (MacKevett and Smith, 1972; MacKevett, 1976). Irregular sulfide-bearing pods occur along the contact; thin quartz veins cut the pluton and the hornfels; and the host rocks are altered. Samples contain up to 5 parts per million (ppm) silver, 15.4 ppm gold, 50 ppm bismuth, and 2,000 ppm copper (MacKevett and Smith, 1968). The Tertiary pluton contains disseminated pyrite and it intrudes Cretaceous sedimentary rocks (MacKevett and Smith, 1972; MacKevett, 1976). This prospect has probably been explored by small surface pits and trenches.
Workings: This prospect has probably been explored by small surface pits and trenches.
Age: Tertiary; the mineralization is partly hosted by a Tertiary pluton.
Alteration: The type of alteration is not specified.
