Kreuger Creek

The Kreuger 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 (Exploration): Status = Inactive

Comment (Geology): Age = Quaternary

Comment (Reference): Primary Reference = Mulligan, 1959 (USBM RI 5493)

Comment (Reserve-Resource): Reserves = Not defined

Comment (Workings): Workings / Exploration = The USBM reports results for 11 churn-drill holes on three lines spaced along 2,600 feet of the drainage (Mulligan, 1959, p. 26).

Comment (Geology): Geologic Description = The segment of Kreuger Creek referred to here is the 0.5 miles at and below the confluence with Eldorado Creek. Eldorado Creek has headwaters that cross the northeast contact zone of the Ear Mountain granite stock (Sainsbury, 1972). This stock is a Late Cretaceous (76.7 +/- 2.9 my; Hudson and Arth, 1983, p. 769) composite biotite granite that intrudes an impure and schistose carbonate sequence, with some metapelitic rocks, of unknown but probable Paleozoic age. The country rocks are variably converted to tactite and hornfels around the granite stock (Knopf, 1908, p. 28-29). Churn-drill holes on this part of Kreuger Creek contain a trace to 0.71 pounds of tin per cubic yard from a pay horizon that varies from 5 to 16 feet thick. Total gravel thickness varies from 6 to 22.5 feet thick. Heavy mineral identifications are not available but the mineralogy here is probably similar to that from the headwaters of Eldorado Creek (TE068).

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