Dixie

The Dixie is a lead, copper, and gold 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.

Alterations

Alteration Type: L
Alteration Text: Wall-rock alteration within a few inches of the vein is intense, but seldom extends more than 10 to 12 inches beyond the quartz filling. Sericitization and carbonate alteration predominate, but there is some pyritization and in the outer parts of the alteration zone chloritization is present (Ray, 1954).

Comments

Comment (Reference): Primary Reference = Chapin, 1921

Comment (Workings): Workings / Exploration = Three claims first staked in 1917 on surface expression of 1 ft of 'good ore'. Very little development reported, the prospect was explored in one place by an open-cut across vein Chapin (1921).

Comment (Geology): Age = Late Cretaceous or younger; the mineralized host is the Late Cretaceous Willow Creek Pluton.

Comment (Geology): Age = Host rock is Late Cretaceous.

Comment (Exploration): Status = Inactive

Comment (Geology): Geologic Description = At least one foot of 'good ore' contains chalcopyrite, pyrite, galena, and free gold on surface (Capps, 1919). An 8.5 ft wide pegmatitic vein strikes N 55 W, and dips 55 SE. The coarse, border material consists of quartz, orthoclase, muscovite, and particles of chalcopyrite along the borders. Central part of vein is milky quartz cut by irregular stringers of chalcopyrite and a little bornite (Chapin, 1921). ? Country rock is the Late Cretaceous Willow Creek Pluton, a zoned pluton: the outer part consists of hornblende quartz diorite and lesser hornblende tonalite; the core consists of hornblende-biotite granodiorite, and lesser hornblende-biotite quartz monzodiorite and biotite quartz monzonite. Wall-rock alteration within a few inches of the vein is intense, but seldom extends more than 10 to 12 inches beyond the quartz filling. Sericitization and carbonate alteration predominate, but there is some pyritization and in the outer parts of the alteration zone chloritization is present (Ray, 1954).
