The occurrence is in Denali National Park and Preserve.
Location: This occurrence is at an elevation of about 4000 feet on the Caribou Creek side of the unnamed ridge that connects Spruce Peak and Kankone Peak, and forms the divide between Myrtle Creek and upper Caribou Creek. It is about 2400 feet northeast of the center of section 21, T. 15 S., R. 16 W., Fairbanks Meridian. The location is accurate within about 500 feet. The site corresponds approximately to the location of sample number 272 of Hawley and Associates (1978), and to occurrence 94 of Thornsberry, McKee, and Salisbury (1984).
Geology: This occurrence is about on the contact between metafelsite and quartz-muscovite schist (Hawley and Associates, 1978, fig. 4.1-A(1). Hawley and Associates correlated these rocks with the upper Precambrian Birch Creek Schist. Bundtzen (1981) and Thornsberry, McKee, and Salisbury, (1984, fig. K-2) subsequently mapped them as lower Paleozoic Spruce Creek sequence. The occurrence consists of a foot-thick, quartz-arsenopyrite-galena vein. The vein assayed 9.9 ppm gold, 340 ppm silver, 8.5 percent lead, 340 ppm copper, 1450 ppm zinc, and 1250 ppm antimony (Hawley and Associates, 1978, fig. 4.1-A(1), number 272). Exposures at and near the site are poor, but the vein could be related to the one at MM045.
Workings: The occurrence was found during geologic mapping in 1976 (Hawley and Associates, 1978). There are no workings.
Age: The deposit is assumed to be Eocene (see record MM091).
Commodities (Major) - Ag, Au, Pb; (Minor) - Cu, Sb, Zn
Development Status: None
Deposit Model: Polymetallic vein (Cox and Singer, 1986; model 22c).
