Location and accuracy The prospect is located in the SW1/4 section 1, T. 9 N., R. 2 W., of the Seward Meridian. The map site is on Bear Creek at an elevation of 1,400 feet. This is location 4 of Cobb and Richter (1972), location 4 of MacKevett and Holloway (1977), location 8 of Cobb and Tysdal (1980), and location S-303 of Jansons and others (1984). The location is accurate to within a quarter of a mile.

Geologic setting

Geologic description

The deposit at the Taylor prospect consists of a 10-inch-wide quartz vein that strikes north and dips 30W. The vein is banded in appearance and contains arsenopyrite, sphalerite, galena, and gold. The arsenopyrite is abundant and occurs both as masses and as well-developed crystals. The vein is exposed only in the creek bed (Tuck, 1933). The host rock is slate (Tuck, 1933) of the Valdez Group of Late Cretaceous age (Nelson and others, 1985).

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

Production and reserves

Workings or exploration The workings on this prospect consist of a single, 130-foot-long adit. Because the vein is exposed in the bed of the creek, it could not be developed by drifting. Therefore, the adit was driven through slide material in hopes of reaching the vein, but bedrock was never encountered (Tuck, 1933). There are no reported production or assay results. The U.S. Bureau of Mines visited the prospect in 1981, but the adit was inaccessible and no samples were collected (Jansons and others, 1984).
