Treasure Creek

The Treasure Creek is a copper and molybdenum 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.

Mine Info

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 = Porphyry Cu-Mo (Cox and Singer, 1986; model 21a)

Comment (Workings): Workings / Exploration = Minor surface workings and shallow drilling. 0.18 oz/ton Au, 2-3% Zn, 0.1-0.5% Cu, and 0.1-0.5% Mo in analysis of arsenopyrite-rich surface boulder (Richter, 1963); up to 1.0% Mo, 2.65% Zn, 1.7 oz/short ton Ag in rock samples from one of the zones (Kurtak and others, 1992).

Comment (Reference): Primary Reference = Kurtak and others, 1992

Comment (Geology): Geologic Description = Disseminated sulfides, fluorite, and epidote in silicified and sheared Tertiary granite stock, and in argillite and metagraywacke intruded by the granite. Local intense argillic alteration and limonite staining adjacent to fault and extending irregularly up to 300 ft (100 m) into granite stock. Argillite and metagraywacke part of extensive Lower Cretaceous flysch unit. Granite stock part of the lower Tertiary McKinley plutonic sequence. 0.18 oz/ton Au, 2-3% Zn, 0.1-0.5% Cu, and 0.1-0.5% Mo in analysis of arsenopyrite-rich surface boulder (Richter, 1963); up to 1.0% Mo, 2.65% Zn, 1.7 oz/short ton Ag in rock samples from one of the zones (Kurtak and others, 1992).

Comment (Geology): Age = Early Tertiary
