Location: Oakland Creek (formerly known as Diomede Creek) drains 4.5 miles northwest 4.5 from headwaters on Potato Mountain (TE024) to its mouth on Lopp Lagoon. The location of placer tin concentrations along this drainage are approximately located; the elevations shown on maps in USBM reports do not seem to match those on modern topographic maps. This is locality 27 of Cobb and Sainsbury (1972). Cobb (1975) summarized relevant references under the name 'Diomede Cr.'.
Geology: 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).
Workings: 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).
