The Last Chance 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 = Schist-hosted gold-quartz vein
Comment (Geology): Geologic Description = Gold has been produced from a steeply dipping quartz vein that is two feet thick and contains arsenopyrite, stibnite, and visible gold. The vein strikes northeast and dips steeply northward (Davis, 1922, p. 59; Chapman and Foster, 1969, p. D18). One hundred and twenty-five tons of ore were mined from short drifts off a 60-foot shaft; the ore reportedly ran $30 in gold per ton (about 0.048 ounce of gold per ton) (Davis, 1922, p. 59-60).
Comment (Workings): Workings / Exploration = One hundred twenty-five tons of ore were mined from short drifts off a 60-foot shaft (Davis, 1922, p. 59-60).
Comment (Reference): Primary Reference = Davis, 1922
Comment (Production): Production Notes = One hundred twenty-five tons of ore were mined from short drifts from a 60-foot shaft; the ore reportedly assayed $30 in gold per ton (about 1.45 ounces of gold per ton) (Davis, 1922, p. 59-60).
Comment (Exploration): Status = Inactive
