Cornelius Creek

The Cornelius Creek is a tungsten 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 = Float prospecting led to the discovery of a 6- to 8-foot thick siliceous bed containing disseminated scheelite. A sample of this material assayed 3.45 percent tungsten oxide over 27 inches (Jasper, 1955). Kodiak Exploration Company sent a sample of mineralized rock from this prospect or from their Chalet Mountain property (KD025) to Wah Chang Corporation for assay and examination. They identified the so-called siliceous material as tactite or skarn (Jasper, 1955).

Comment (Workings): Workings / Exploration = Sample collected across 27 inches contained 3.45 percent tungsten oxide.

Comment (Deposit): Model Name = W skarn? (Cox and Singer, 1986; model 14a)

Comment (Exploration): Status = Inactive

Comment (Reference): Primary Reference = Rose and Richter, 1967

Comment (Geology): Age = Cretaceous or younger
