The prospect is in Denali National Park and Preserve.
Location: This prospect is on the west side of the canyon of the upper West Fork of Glen Creek at an elevation of about 3250 feet. It is about 0.5 mile due west of the center of section 1, T. 16 S., R. 17 W., Fairbanks Meridian. The location is accurate within 300 feet. The prospect corresponds to occurrence 68 of Thornsberry, McKee, and Salisbury (1984) and approximately to the location of soil sample 240 of Hawley and Associates (1978).
Geology: The country rock in the area of this prospect is mainly metafelsite of the Spruce Creek sequence; it strikes ENE and dips SE, along the south flank of the Kantishna antiform (MM091) (Bundtzen, 1981; Thornsberry, McKee, and Salisbury, 1984, fig. K-2). The deposit is a foot-thick quartz vein that strikes north and is nearly vertical. The vein contains several percent of arsenopyrite, pyrite, stibnite, and probably galena. Samples of the vein assayed a trace of gold, 1.6 ounces of silver per ton, 1.45 percent lead, 1.2 percent antimony, and 2.25 percent arsenic (Thornsberry, McKee, and Salisbury, 1984, v. 2). A soil sample collected on apparently mineralized residual soil near the prospect contained 13 ppm silver, 0.71 ppm gold, 600 ppm lead, and 500 ppm zinc (sample 240, Hawley and Associates, 1978, fig. 4.1-A(1)).
Workings: The vein was explored shallow pits of unknown date.
Age: The deposit is assumed to be Eocene (see record MM091).
