Location: This occurrence is on the ridge crest between the headwaters of Nesbit and Stab Creeks at an elevation 2,400 feet. It is 3,500 feet northwest of Chauik Mountain which is 3,464 feet high.
Geology: This occurrence is a thin gossan zone, about 10 inches wide, that trends across the ridge crest. It may be along a small fault. A grab sample contained 12.4 % Pb, 3.45 ounces/ton Ag, 6,250 ppm Zn, and less than 5 ppb Au (Hudson and Wyman, 1983). This base metal occurrence, and several others in this part of the Bendeleben A-4 quadrangle, are in high grade metasedimentary rocks that are structurally above or peripheral to the crosscutting Pargon pluton. The Pargon pluton is mostly granodiorite and assumed to be Cretaceous in age (Till and others, 1986). It was emplaced at shallower depths than the more deep-seated Bendeleben pluton to the east.
Workings: No workings are present and only reconnaissance sampling has been done.
Age: Cretaceous; this occurrence is probably related to emplacement of the Pargon pluton which is assumed to be Cretaceous in age.
Alteration: Oxidation; thin gossan zone in metasedimentary rocks.
Commodities (Major) - Ag, Pb, Zn
Development Status: None
Deposit Model: Galena-bearing vein in high grade metasedimentary rocks
