Location and accuracy The Wieler Antimony prospect is at an elevation of about 2850 feet on the south side of the West Fork of Glen Creek. It is about 0.2 mile above the junction of the East and West forks of the creek, in the N1/2 of the NE1/4 SE1/4, section 1, T. 16 S., R. 17 W., Fairbanks Meridian. The location is accurate within 500 feet. The prospect is number 75 of Thornsberry, McKee, and Salisbury (1984).

Geologic setting

Geologic description

The country rocks in the area of the Wieler Antimony prospect are graphitic and chloritic schists of the upper Precambrian Birch Creek Schist (Bundtzen, 1981; Thornsberry, McKee, and Salisbury, 1984, fig. K-2).
The deposit consists of discontinuous, en echelon, quartz pods that contain disseminated to massive pyrite, galena, sphalerite, and stibnite. The pods are aligned NE, transverse to a high-angle, WNW- to NNW-striking, fault that controls the course of lower Glen Creek. The pods are exposed in a placer cut for a distance of 50 feet. Selected samples of the mineralized quartz contained 8.55-10.5 percent lead, 3.1-10.5 percent zinc, and 7.35-9.05 percent antimony (Thornsberry, McKee, and Salisbury, 1984, v. 2, occurrence 75).
Geologic map unit (, )
Mineral deposit model Polymetallic vein (Cox and Singer, 1986; model 22c).
Mineral deposit model number 22c
Age of mineralization The deposit is assumed to be Eocene (see record DN091).

Production and reserves

Workings or exploration The Wieler Antimony deposit was discovered during placer mining; the pit that exposed the sulfide-bearing quartz was opened in 1983 (Thornsberry, McKee, and Salisbury, 1984, v. 2). The property has been inactive since about 1985.
Indication of production None

Additional comments

The prospect is in Denali National Park and Preserve.
