This occurrence is in Denali National Park and Preserve.
Location: This occurrence is at an elevation of about 4300 feet on an unnamed ridge between upper Myrtle and upper Caribou creeks. It is about 1.1 miles northeast of Spruce Peak, in the SW1/4 SW1/4 section 21, T. 15 S., R. 16 W., Fairbanks Meridian. The location is accurate within 500 feet. The occurrence corresponds to number 58 of Bundtzen, Smith, and Tosdal (1976), 278 of Hawley and Associates (1978), and 66a of Bundtzen (1981).
Geology: This occurrence is a stratabound gossan about 6 feet wide which can be traced northeasterly for at least 250 feet. It appears to be a continuation of, or parallel to, gossan exposed about 1500 feet to the northeast. The gossan is mainly in metafelsite of the lower Paleozoic Spruce Creek sequence; some also occurs nearby in graphitic schist (Hawley and Associates, 1978; Bundtzen, 1981, and Thornsberry, McKee, and Salisbury, 1984). The gossan marks half-inch-thick, stratiform bands in the metafelsite that contain up to 50 percent pyrite. Bundtzen, Smith, and Tosdal (1976) tentatively identified vanadinite, a secondary lead-vanadium mineral, in the bands. Gossan sampled by Hawley and Associates (1978) contained 1.7 ppm silver, 1050 ppm lead, and 240 ppm zinc.
Workings: There are no workings.
Age: This stratabound, possibly syngenetic deposit may be lower Paleozoic, the protolith age of the Spruce Creek rocks.
Alteration: Oxidation of iron and lead-vanadium(?) minerals.
Commodities (Major) - Pb; (Minor) - Ag, V(?), Zn
Development Status: None
Deposit Model: Stratabound deposit in metafelsite.
