This occurrence is within the road cut and is probably within the right-of-way of the road and hence is closed to mineral entry.
Location: This occurrence is located just east of the town of Whitter along the road that leads to Cove Creek. It is in the SE1/4 section 13, T. 8 N., R. 4 E., of the Seward Meridian. This is location S-179 of Jansons and others (1984) and is accurate to within a quarter of a mile.
Geology: This occurrence consists of two veins hosted in slate and quartzite of the Valdez Group of Late Cretaceous age (Jansons and others, 1984). One vein located in a road cut, is 2 to 3 inches wide and contains pyrite. The second vein crops out in the road bed; it is 4 to 16 inches wide and contains chalcopyrite, gold, pyrite, and pyrrhotite. Six grab samples from the road cut assayed by the U.S. Bureau of Mines contained less than 1 ppm gold. One grab sample from the vein in the road bed contained 2.9 ppm gold (Hoekzema and Sherman, 1983).
Workings: The U.S. Bureau of Mines sampled this occurrence in 1981 and collected seven grab samples. The samples contained from nil to 2.9 ppm gold and less than 1 ppm silver (Jansons and others, 1984).
Age: Cretaceous or younger; the veins cut rocks of the Valdez Group of Late Cretaceous age.

Commodities (Major) - Au; (Minor) - Cu
