Metal Creek

The Metal Creek is a silver 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.

Comments

Comment (Exploration): Status = Inactive

Comment (Geology): Age = Late Cretaceous or younger, veins cut and intrusive rocks intrude the Late Cretaceous Valdez Group sedimentary rocks.

Comment (Deposit): Other Comments = Abundance of scheelite in concentrates is enough to warrant prospecting of the area between Metal Creek and Glacier Fork (Richter, 1967).

Comment (Workings): Workings / Exploration = Richter (1967) mentions the only lode deposits of economic significance observed in place to be the small quartz diorite stock at headwaters. Samples assayed 0.02 oz/ton gold, 0.26 oz/ton silver, and 0.08 percent copper. Float samples taken downstream show same amount, 0.02 oz/ton, of gold to be present, but silver and copper were undetectable.

Comment (Geology): Geologic Description = Country rock along Metal Creek is Valdez Group interbedded slate, siltstone, and graywacke of Late Cretaceous age that have been metamorphosed to phyllite and quartz mica schist. These rocks are tightly folded, exhibit strong foliation, strike N 10-30 E, and dip nearly vertical. At the headwaters of Metal Creek and Glacial Fork, greenstone containing discontinous dikes and one stock of quartz diorite are present (Lande, 1927). Quartz veins with pyrite and chlorite are common in the area. Samples assayed 0.02 oz/ton gold, 0.26 oz/ton silver, and 0.08 percent copper (Richter, 1967).

Comment (Reference): Primary Reference = Richter, 1967
