Location: The Moonshine Mine is located 1.5 km (4,800 feet) ESE of Dolomi Mountain (coordinates of record) and about 0.3 mile W of the center of Lake Williams and about 0.6 mile SE of the center of section 31, T77S, R89E. The location is accurate to within 0.1 mile.
Geology: The Moonshine Mine was discovered before 1914, and produced a little ore (Smith, 1914; Chapin, 1916). The workings consist of two adits, 68 and 78 feet long, and an open cut; the longer adit has a winze and a small stope. As described by Maas and others (1991,1995), a quartz vein 3.2 to 4.3 feet thick is exposed in the open cut for about 100 feet; the vein strikes N60W and dips 40N. The two adits penetrate the hanging wall of the vein exposed in the open cut and intersect several other veins. Several samples across the vein in the open cut contained 60 to 390 parts per billion gold. The highest gold values were in a 0.7-foot quartz vein in one of the adits: 3 samples contained 0.723 to 63.195 ounces of gold per ton. Smith (1914) indicates that the veins contain pyrite and tetrahedrite. Chapin (1916) describes the deposit as blocks of marble and schist cut by a network of quartz veins with disseminated chalcopyrite and pyrite. The rocks in the Dolomi area are part of the Wales Group of Late Proterozoic and Cambrian age (Herreid, 1967). They are folded into a large dome centered over the eastern third of Paul Lake, and consist of several marble layers 200 to 1300 feet thick, interbedded with calcareous chlorite schist and marble.
Workings: The workings consist of two short adits, one with a winze and a small stope, and an open cut.
Age: Veins are younger than the Late Proterozoic or Cambrian host rocks.
Production: Minor production prior to 1914.
Reserves: None.
Commodities (Major) - Ag, Au, Cu
Development Status: Yes; small
Deposit Model: Low-sulfide gold-quartz vein (Cox and Singer, 1986; model 36a).
