Location: Located a few hundred ft. (about 100 m) west of VABM 3081 on Rabbit Mtn. midway between locality 1 of Barker (1981, p. 25) and locality 2 of Barker and Clautice (1978, p. 14); located to within 2 mi (3.2 km).
Geology: Rhyolite dikes <100 feet (30.5 m) thick intrude argillite in a sequence of phyllite siltstone and quartzite. Small gossans occur in argillite; pyrite locally occurs in quartzite (Barker, 1981, p. 81).
Workings: Sedimentary rocks contain up to 26 ppm Ag, 2200 ppm Zn, 2% Cu and 1.5% Pb (Brosge and Reiser 1968). Small gossan yields 1100 ppm Cu, 11.2% Pb, 6700 ppm Zn, 115 ppm Ag, 1.8 ppm U and 7.5 ppm Th. Pyritic quartzite contains 68 ppm Cu, 610 ppm Pb, 390 ppm Zn. Soils contain <83 ppm Cu, 420 ppm Pb, 270 ppm Zn (Barker, 1981, p. 81-8).
Alteration: Minor argillic alteration and silicification
Commodities (Major) - Ag, Cu, Pb, Zn; (Minor) - Th, U
Development Status: No
Deposit Model: Polymetallic lodes (veins?) associated with rhyolite dikes
