The Goodwin 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 (Exploration): Status = Inactive
Comment (Reference): Primary Reference = Heide and Sanford, 1948; Mulligan, 1966
Comment (Workings): Workings / Exploration = Primarily widely spaced USBM churn-drill holes.
Comment (Production): Production Notes = Very minor; perhaps some near the mouth of Goodwin Gulch and several hundred pounds of tin-bearing concentrate from the headwater forks of Wales Creek.
Comment (Reserve-Resource): Reserves = Not defined; a narrow pay streak has been locally identified.
Comment (Geology): Geologic Description = Goodwin Creek passes over Mississippian marble and limestone (Sainsbury, 1972); it does not directly drain uplands of the Late Cretaceous Cape Mountain biotite granite (Hudson and Arth, 1983) or its contact. However, three tributaries, including Goodwin Gulch (TE004), flow northward to Goodwin Creek from headwaters in the uplands of Cape Mountain. Two USBM churn-drill holes (Heide and Sanford, 1948) indicate a narrow pay streak with average grades of 4 pounds tin per cubic yard for 1000 feet downstream from the mouth of Goodwin Gulch (Mulligan, 1966, p. 19). Little tin is found in Goodwin Creek above the mouth of Goodwin Gulch. Three USBM churn-drill holes (Heide and Sanford, 1948) further downstream below the mouth of Wales Creek (not located on existing maps, see location above), identify another 1000 foot-long pay streak which averages one pound tin per cubic yard (Mulligan, 1966, p. 19). Wales Creek is reported to have yielded several hundred pounds of tin-bearing concentrate to hand mining of a small depression at the headwater forks (Mulligan, 1966, p. 21).
Comment (Deposit): Model Name = Alluvial tin placer (Cox and Singer, 1986; model 39e)
