Curry

The Curry is a 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 (Geology): Geologic Description = Narrow quartz veins, with minor amounts of molybdenite, and aplite dikes cut a 300 to 500 feet wide dike-like body of Tertiary and (or) Cretaceous (TKi) quartz diorite. Country rock is a Mesozoic marine sedimentary sequence of black slate and schist (KJs). (Smith, 1942; MacKevett and Holloway, 1977; Reed and Nelson, 1980).

Comment (Deposit): Model Name = Neither Cox and Singer (1986) nor Bliss (1992) have deposit models that conform to this type of molybdenite occurrence exactly. The best match is porphyry Mo, low-F (Cox and Singer, 1986; model 21b).

Comment (Reference): Primary Reference = Cobb and Reed, 1980

Comment (Workings): Workings / Exploration = This site is granite quarry, now abandoned; rock chip sampling is all that has been done here.

Comment (Geology): Age = Tertiary and (or) Cretaceous; mineralization is interpreted to be linked to the quartz diorite host rock mapped as TKi by Reed and Nelson (1980).
