Geologic information

Identification information

Deposit ID 10307365
Record type Site
Current site name Unnamed (Dick Creek drainage)

Geographic coordinates

Geographic coordinates: -144.31244, 60.34962 (WGS84)
Relative position This site represents several occurrences in an approximately 15-sq.-mi area in the Dick Creek drainage. The roughly circular area is bounded on the south by Bering Lake and on the north, west, and east by the drainage divides of the tributaries of Dick Creek. The map site is about at the center of the area in the SW1/4, sec. 35, T. 17 S., R. 6 E., of the Copper River Meridian.

Economic information

Comments on the geologic information

  • Geologic Description = These occurrences consist of anomalous metal values in stream sediment from concretionary sandstone of the Tertiary Tokun Formation (Winkler and Plafker, 1991). Stream sediment concentrate samples contain >2% Zn (Goldfarb and others, 1992).
  • Age = Tertiary, based on probable source of samples.

Economic information about the deposit and operations

Development status Occurrence

Comments on exploration

  • Status = Inactive

Mining district

District name Copper River

Comments on the workings information

  • Workings / Exploration = None. Investigations of similar geochemical anomalies to the south on Kayak Island (Pickthorn and others,1985) failed to find any outcrops containing mineral deposits (Goldfarb and others, 1992). Stream sediment concentrate samples contain >2% Zn (Goldfarb and others, 1992).

General comments

Subject category Comment text
Deposit Model Name = Possibly sedimentary-exhalative Pb-Zn (Cox and Singer, 1986; model 31a)
Deposit Other Comments = This and other geologically similar areas in the Cordova quadrangle warrant further investigation (Nelson and others, 1994). Chugach Alaska Corporation, Anchorage, Alaska has control of these lands.
