The Goodwin 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 = Hill, 1933
Comment (Workings): Workings / Exploration = A crosscut was caved, but several open cuts and pits were observed when visited by Hill in 1931 (Hill, 1933, p. 153).
Comment (Deposit): Model Name = Schist-hosted gold-quartz vein
Comment (Exploration): Status = Inactive
Comment (Geology): Geologic Description = The Goodwin gold prospect consists of a 50-foot-wide zone of brecciated iron-stained schist that strikes N. 70 E. and has a vertical dip (Hill, 1933, p. 153). In 1931, Hill attempted to determine the average value of this zone by taking grab samples from various dumps; these samples assayed only 23 cents in gold per ton (Hill, 1933, p. 153-154). Bedrock in the area is Fairbanks Schist that consists of quartz-muscovite schist, quartzite, and chlorite-quartz schist (Newberry and others, 1996).
