Identification information

Deposit ID 10308699
Record type Site
Current site name Big River

Geographic coordinates

Geographic coordinates: -159.93245, 55.93925 (WGS84)
Relative position This occurrence is located on the Alaska Peninsula near the head of Big River, which enters Stepovak Bay just west of Stepanof Flats (Christie, 1974, color anomaly 85; MacKevett and Holloway, 1977, locality 5; Wilson and others, 1988, locality 5). The map site is at an elevation of 1,200 feet, at the northeast corner of sec. 5, T. 49 S., R. 68 W., of the Seward Meridian. The location is accurate to within 1 mile.

Comments on the geologic information

  • Geologic Description = The country rocks at this site are Quaternary volcanic rocks (Wilson and others, 1995). Christie (1974) described this occurrence as disseminated pyrite in vesicular volcanic rocks. Fields (1977), however, describes a color anomaly near the head of Big River that is developed in pyritized andesites, agglomerates, acid tuffs, and sedimentary rocks. Apparently, there are several color anomalies in this area.
  • Age = Quaternary.

Mining district

District name Alaska Peninsula

Comments on the workings information

  • Workings / Exploration = An Aleut-Quintana-Duval joint venture examined the area in of this occurrence 1974 (Christie, 1974). Bear Creek Mining Company examined it in 1977 (Fields, 1977). The U.S. Geological Survey sampled in this general area in the mid-1980's (Wilson and others, 1988).
