The Unnamed (on north side of Dillon Creek) is a copper, silver, zinc, and lead mine located in Alaska.
About the MRDS Data:
All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Exploration): Status = Inactive
Comment (Deposit): Model Name = Zn-Pb skarn? Polymetallic vein ? (Cox and Singer, 1986; model 18c or 22c ?)
Comment (Reference): Primary Reference = Gamble, 1988
Comment (Workings): Workings / Exploration = No workings are known at this locality.
Comment (Deposit): Model Number = 18c ?, 22c ?
Comment (Geology): Geologic Description = Gossan float from near calc-silicate hornfels outcrops contains azurite, bornite (?), chalcopyrite, and malachite. Two grab samples contain 100 ppm Ag each, 700 and 110 ppm Cd, greater than 2 % Pb, 3.4 % and 8,000 ppm Zn, and 12 and 14 ppm Sb (Gamble, 1988). There is also some malachite staining in a felsic dike near this locality (Briskey, 1983). This occurrence, and several others in this part of the Bendeleben A-4 quadrangle, are in high grade metamorphic 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. The metamorphic rocks peripheral to the western Pargon pluton are also intruded by small, felsic dikes and plugs including quartz porphyry and muscovite granite.
Comment (Geology): Age = Cretaceous; this occurrence is probably related to emplacement of the Pargon pluton which is assumed to be Cretaceous in age.
