Location: Big Creek prospect is located within section 7, T. 20 N., R. 22 E., of the Copper River Meridian, at about 3000 feet elevation on a northwest facing hillside above Big Creek. It is location 12 of Singer and others (1976), and location 3 of Eberlein and others (1977). The location is accurate to within a mile.
Geology: The Big Creek prospect is in an area of possible stratiform sulfide deposits. It consists of galena, sphalerite and iron sulfides disseminated in quartz-mica schist of Paleozoic and/or Precambrian age (Eberlein and others, 1977, p. 101). The regional geology around the prospect consists of amphibolite-grade quartz-mica schist that is Precambrian to Paleozoic in age (Foster, 1970). High copper anomalies were found in soil samples collected during the early 1970's, although no primary mineralization was found on the surface (David Hedderly-Smith, oral communication, 1998).
Workings: Surface exploration and soil sampling conducted in the 1970's. There probably has been more recent exploration in the area.
