The Tomboy Creek is a gold 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 = Placer gold mining took place on Tomboy Creek in 1902; the U.S. Geological Survey obtained pans of about 1.5 cents or 2.25 dollars per cubic yard from decomposed schist bedrock (Collier and others, 1908, p. 219). The overlying several feet of gravel contains numerous pebbles and cobbles of granitic bedrock reworked from glacial deposits that originated in the Kiglauik Mountains. The source of the gold is unknown. The area to the north of the mine is extensively covered by glacial deposits. Near the mine, Sainsbury, Smith, and Kachadoorian (1972) mapped a strong northwest-trending fault, which separates graphitic schist to the south from chloritic, metavolcanic rocks near this mine.
