Geologic information

Identification information

Deposit ID 10001609
MRDS ID A012373
Record type Site
Current site name Lone Wolf (southwest of Nadzaheen Cove)

Geographic coordinates

Geographic coordinates: -131.48565, 55.21863 (WGS84)
Relative position This site represents 3 occurrences at an elevation of about 500 feet on a knoll about 0.9 mile southwest of Nadzaheen Cove The map site is in section 1, T. 77 S., R. 92 E., of the Copper River Meridian, at the approximate center of the quarter-square-mile area that contains the occurrences. The site corresponds to loc. 12 in Berg (1972 [I 684]), loc. 131 in Elliott and others (1978), and loc. 10a-c in Karl (1992). The location is accurate within 0.1 mile.

Comments on the geologic information

  • Geologic Description = The country rocks in the area of this site are Upper Jurassic or Cretaceous flyschlike metasedimentary rocks that are gradationally interbedded with recrystallized andesitic or basaltic volcanic flows and tuff (Berg, 1972). The rocks were regionally metamorphosed to greenschist-grade phyllite and semischist in Late Cretaceous time.? the Lone Wolf prospect consists of several trenches along a fault zone that contains abundant quartz veins (Karl, 1992, loc. 10). The hostrock is gray, thinly-laminated quartz phyllite; both the phyllite and the quartz veins are folded and faulted. A six-foot-thick vein, which has been traced on the surface for about 300 feet, cements greenstone and phyllite breccia, and contains muscovite, calcite, and pyrite. Other veins in the area have cumulative widths of up to about 60 feet. A sample of a pyritic quartz vein contained 0.88 ppm Au; and a sample of pyritic green phyllite contained 0.56 ppm Au (Karl, 1992). Samples of pyrite- and galena-bearing quartz veins collected by the USGS in the 1930s contained 0.71 oz. Au/ton and 0.91 oz. Ag/ton; and 7 chip samples collected in 1975 by private interests contained as much as 0.23 oz. Au/ton (Berg, 1972; Karl, 1992).
  • Age = Probably Late Cretaceous or younger.

Comments on the workings information

  • Workings / Exploration = The Wolf prospect has been explored by several trenches. A sample of a pyritic quartz vein contained 0.88 ppm Au, and a sample of pyritic green phyllite contained 0.56 ppm Au (Karl, 1992). Samples of pyrite- and galena-bearing quartz veins collected by the USGS in the 1930s contained 0.71 oz. Au/ton and 0.91 oz. Ag/ton; and 7 chip samples collected in 1975 by private interests contained as much as 0.23 oz. Au/ton (Berg, 1972; Karl, 1992).
