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 (Reference): Primary Reference = Doyon Limited, 1998
Comment (Geology): Geologic Description = The area around the Last Chance Creek placers is characterized by rounded hills and flat-topped ridges (Thomas, 1970). The most prominent ridge is Black Mountain, which trends about 12 miles in a northerly direction and is underlain by Cretaceous granodiorite (Weber and others, 1978). A combination of augen gneiss, gneissic schist, and schist are to the west of Black Mountain. There is intense shearing and faulting in the contact between the metamorphic and intrusive rocks. This shearing is observed in the underground workings and at the surface as pronounced saddle-like depressions across the spurs separating the westward-flowing tributaries of Tibbs Creek. This shear zone trends roughly N15E and dips 65 degrees NW (Thomas, 1970). ? the Goodpaster region was first explored for placer gold in 1915. Thomas (1970) reports a stampede of prospectors in 1915 that ended soon after due to low grade deposits. In the early 1930's, gold-bearing quartz veins were discovered in the upper Tibbs Creek area. Cobb (1973) reports insignificant placer gold production from the Goodpaster region. The Alaska Division of Mining Kardex file system records active claims on Last Chance Creek as recent as 1984. No production totals for Last Chance Creek are available.
