Deposit ID 10308098
Record type Site
Current site name Pmrgx-17

Geographic coordinates

Geographic coordinates: -160.54943, 55.54724 (WGS84)
Relative position This occurrence is located on the Alaska Peninsula about 1 mile east of Balboa Bay. The map site is at an elevation of about 1,000 feet, at the center of sec. 36, T. 53 S., R. 74 W., Seward Meridian (Christie, 1974, color anomaly 77; Wilson and others, 1988, locality 66). The site is referred to as PMRGX-17 in Wilson and others (1988). The location is accurate to within 1,200 feet.

Comments on the geologic information

  • Geologic Description = This occurrence is a 3,000- by 5,000-foot color anomaly (Christie, 1974). The country rocks in the area of the anomaly are volcanic breccias and agglomerates underlain by arkosic and argillaceous sedimentary rock. The volcanic rock, mapped as Miocene (Wilson and others, 1995), is interpreted by Christie to be a vent complex containing sulfides that may be related to fumarolic activity. The rocks exhibit argillic alteration. A silt sample collected by an Aleut-Quintana-Duval joint venture in 1974 contained 0.34 ppm gold. Three samples collected by the U.S. Geological Survey in the mid-1980's were reported to be anomalous in arsenic, barium, gold, lead, and zinc (Wilson and others, 1988).
  • Age = Miocene or younger.

Comments on the workings information

  • Workings / Exploration = An Aleut-Quintana-Duval joint venture briefly mapped and took silt samples in this area in 1974. One sample contained 0.34 ppm gold. Samples 83AYb554, and 557-558 collected during U.S. Geological Survey studies in the mid-1980s were reported to be anomalous in arsenic, barium, lead, and zinc (Wilson and others, 1988).
