Location and accuracy This occurrence is located in the N1/2 section 23, T. 8 N., R. 1 W., of the Seward Meridian, at the confluence of East Fork Sixmile and Gulch Creeks. This is location S-279 of Jansons and others (1984). The location is accurate to within a quarter of a mile.

Geologic setting

Geologic description

This occurrence consists of auriferous, sulfide-bearing quartz veins in slate and graywack of the Valdez Group of Late Cretaceous age (Jansons and others, 1984; Nelson and others, 1985). A chip sample was collected that assayed a trace of gold and silver (Jansons and others, 1984). No workings are reported.

Mineral deposit model Low-sulfide Au-quartz veins (Cox and Singer, 1986; model 36a)
Mineral deposit model number 36a
Age of mineralization Cretaceous or younger; the veins cut rocks of the Late Cretaceous Valdez Group of Late Cretaceous age.

Production and reserves

Workings or exploration No workings or other improvements are present. A mining claim was staked on the occurrence in 1953 (Hoekzema and Sherman, 1983). The U.S. Bureau of Mines briefly examined several quartz veins in 1981, but none of the veins contained any visually significant ore minerals. A chip sample was collected that assayed at a trace of gold and silver (Jansons and others, 1984).
Indication of production None
