The prospect is in Denali National Park and Preserve.
Location: The Friday Rim prospect is at an elevation of about 3050 feet on the south flank of the ridge north of Friday Creek . It is in the SE1/4 SE1/4 section 2, T. 16 S., R. 18 W., Fairbanks Meridian. The location is accurate within 500 feet. The prospect corresponds to number 19 of Bundtzen, Smith, and Tosdal (1976) and 30 of Thornsberry, McKee, and Salisbury (1984).
Geology: The Friday Rim prospect area is underlain by quartz-rich Birch Creek schist that dips to the northwest (Hawley and Associates, 1978, fig. 4.1-1(A); Thornsberry, McKee, and Salisbury, 1984, fig. K-2, v. 2). The Birch Creek schist is probably late Precambrian (Bundtzen, 1981). At the prospect, a pit exposes a quartz-siderite vein that contains a little pyrite. Samples of the vein assayed up to 0.05 ounce of gold per ton and small amounts of lead and zinc (Bundtzen, 1981). Near the pit, Hawley and Associates (1978, fig. 4.1-1(A) ) sampled reddish soil (no. 82) that contained slightly anomalous amounts of silver, lead, and zinc. Soil (no. 81) collected a few hundred feet away contained 2.8 ppm silver, 505 ppm lead, and 315 ppm zinc.
Workings: The vein was explored by a 4- x 4- x 4-foot pit of unknown date.
Age: The deposit is assumed to be Eocene (see record MM091).
Commodities (Major) - Ag(?); (Minor) - Pb, Zn
