The Saddle 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 (Deposit): Model Name = Alluvial tin placer (Cox and Singer, 1986; model 39e)
Comment (Geology): Geologic Description = Saddle Creek has headwaters in the southeast contact zone of the Ear Mountain biotite granite stock. This 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). One of two USBM churn-drill holes on the lower part of the creek (about 340 feet elevation) contained 0.01 pounds of tin per cubic yard. Samples from these holes contain quartz, calcite, grossularite garnet, albite, limonite pseudomorphs after pyrite, traces of blue tourmaline, brown tourmaline, epidote, and idocrase. Cassiterite was also identified (Mulligan, 1959, p. 29).
Comment (Workings): Workings / Exploration = Two USBM churn-drill holes were completed on the lower part of the creek at approximately 340 feet elevation (Mulligan, 1959, p. 20).
Comment (Reference): Primary Reference = Mulligan, 1959 (USBM RI 5493)
Comment (Exploration): Status = Inactive
