The Last Chance 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 (Deposit): Model Name = Placer Au (Cox and Singer, 1986; model 39a)
Comment (Deposit): Other Comments = Prospect was called Crab Creek by Reed (1938), but it is called Last Chance Creek on the modern topographic map.
Comment (Reference): Primary Reference = Reed, 1938
Comment (Workings): Workings / Exploration = Last Chance Creek was prospected by at least three shafts to bedrock and an open cut. A 30-foot shaft was sunk in 1922 and 15-foot and 35-foot shafts were sunk in 1932. The 15-foot shaft reportedly was near the mouth of the creek and the 35-foot shaft was farther upstream 'at the forks'. Claims have been staked on Last Chance Creek since 1969, but there are no reports of any work.
Comment (Geology): Geologic Description = Prospecting in 1922 yielded two grains of coarse gold at the bottom of a 30-foot-deep prospect shaft (Reed, 1938). Additional prospecting in 1932 yielded one grain of gold (said to be worth $0.05) from a 4-foot open cut near where the stream valley opens into the valley of Lake Creek. No other data are available for this occurrence.
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Quaternary.
