The prospect is in Denali National Park and Preserve and is inactive.
Location: This prospect is at an elevation of about 3400 feet on the southwest flank of Wickersham Dome, a short distance northeast of the north end of Quigley Ridge. It is in the SW1/4 SW1/4 section 6, T. 16 S., R. 17 W., Fairbanks Meridian. The location is accurate within 300 feet. The prospect corresponds to number 38 of Bundtzen (1981) and number 82 of Hawley and Associates (1978). It is number 42 of Thornsberry, McKee, and Salisbury (1984), although numbers 43 and 42 appear to be interchanged on their map (fig. K-8).
Geology: The country rock at this prospect is mainly feldspathic quartz schist of the Birch Creek Schist. The schist is cut by lower Tertiary basaltic dikes (Bundtzen, 1981; Thornsberry, McKee, and Salisbury, 1984). The deposit consists of a sulfide-bearing quartz-siderite vein that cuts the basalt, and of disseminated pyrite and arsenopyrite in argillic(?)-altered basalt. The vein is sparsely mineralized. The highest silver content in four samples was 0.22 ounce per ton; lead content was as much as 0.17 percent, arsenic averaged about 300 ppm, and one sample contained 35 ppm molybdenum (Bundtzen, 1981, p. 219). The vein is Tertiary; it cuts mafic dikes which have been dated as Eocene (Bundtzen and Turner, 1979).
Workings: The prospect was explored by several pits of unknown date.
Age: The vein is Tertiary; it cuts mafic dikes which have been dated as Eocene (Bundtzen and Turner, 1979).
Alteration: Sulfidization and argillic(?) alteration of basalt. Iron-oxide alteration.

Commodities (Major) - Ag; (Minor) - As, Mo, Pb
