The occurrence is in Denali National Park and Preserve.
Location: This occurrence is at an elevation of about 4000 feet on the east flank of Glacier Peak about 1/2 mile northeast of hilltop 4310. It is about 0.4 mile due east of section 35, T. 15 S., R. 17 W., Fairbanks Meridian. The location is accurate within 500 feet. The occurrence corresponds to number 49 of Bundtzen, Smith, and Tosdal (1976), 215 of Hawley and Associates (1978), 57 of Bundtzen (1981), and 71 of Thornsberry, McKee, and Salisbury (1984).
Geology: The country rock in the area of this occurrence is west-dipping micaceous quartz schist of the upper Precambrian Birch Creek Schist (Bundtzen, 1981; Thornsberry, McKee, and Salisbury, 1984). The occurrence, a poorly-exposed outcrop, consists of a mineralized quartz-siderite vein that strikes NE and is nearly vertical. The vein contains boulangerite, pyrite, and probably sphalerite and galena. Mineralogically, the vein is similar to the one at the nearby Glenn prospect (MM075). A selected sample assayed 9.37 ounces of silver per ton, 3.5 percent lead, 2.6 percent zinc, and 1.19 percent antimony. Soils collected nearby were anomalous (Hawley and Associates, 1978, fig. 4.1-A(1)). Soil sample 215, collected near the occurrence, was anomalous in lead, zinc, silver, and gold; sample 229, collected downslope east of the occurrence, was anomalous in gold.
Workings: The deposit was discovered during regional geologic mapping by Bundtzen, Smith, and Tosdal (1976).
Age: The deposit is assumed to be Eocene (see record MM091).

Commodities (Major) - Ag; (Minor) - Au, Pb, Sb
Development Status: None
Deposit Model: Polymetallic vein (Cox and Singer, 1986; model 22c).
