Comments on the geologic information

  • 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).
  • Age = Late Cretaceous or younger, veins cut and intrusive rocks intrude the Late Cretaceous Valdez Group sedimentary rocks.

Economic information about the deposit and operations

Development status Occurrence
Commodity type Metallic

Comments on exploration

  • Status = Inactive

Mining district

District name Anchorage

Comments on the workings information

  • 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.

General comments

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