Oakland Creek (formerly known as Diomede Creek)

The Oakland Creek (formerly known as Diomede Creek) is a tin 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): Age = Quaternary

Comment (Reference): Primary Reference = Heide and Rutledge, 1949

Comment (Reserve-Resource): Reserves = Not defined

Comment (Workings): Workings / Exploration = The USBM completed 17 churn-drill holes to bedrock along 4 lines spread out over 5,600 feet of the drainage length (Heide and Rutledge, 1949).

Comment (Deposit): Model Name = Alluvial tin placer (Cox and Singer, 1986; model 39e)

Comment (Exploration): Status = Inactive

Comment (Geology): Geologic Description = Bedrock in the headwaters of Oakland Creek is thermally metamorposed thin-bedded metapelite, metasandstone, and minor impure metacarbonate rocks of unknown but probable Paleozoic age. These rocks makeup the relatively resistant upland of Potato Mountain that is interpreted to be underlain at depth by biotite granite (Hudson and Reed, 1997, p. 454). Three to ten feet of overburden are present on gravels that locally reach 37 feet of thickness. The USBM churn-drill results are for pay sections on bedrock that are generally 1 to 6 feet thick but in two holes the gravel and pay thickness were both much greater (27 and 35 feet of pay in gravel sections 34 and 37 feet thick respectively). Tin concentrations between 0.04 and 0.24 pounds of tin per cubic yard were returned from 12 of 17 USBM churn-drill holes (Heide and Rutledge, 1949, p. 20). The tin concentrations are higher in lower parts of the sampled drainage (elevations estimated to be between 150 to 200 feet). This is close to where a Pleistocene strandline has been inferred from the geomorphic character of the area (Hudson and Reed, 1997, p. 454).
