The Engineer 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 (Geology): Geologic Description = The Engineer prospect is located along a ridge composed of Fairbanks Schist, which consists of quartz-muscovite schist, quartzite, and chlorite-quartz schist (Newberry and others, 1996). A grab sample from two, parallel, iron-stained, arsenopyrite-bearing quartz veins oriented N. 70 E., assayed $2.86 per ton or 0.14 ounce of gold per ton (Hill, 1933, p. 153).
Comment (Exploration): Status = Inactive
Comment (Reference): Primary Reference = Hill, 1933
Comment (Workings): Workings / Exploration = When visited by Hill in 1931, the few prospect pits were caved (Hill, 1933, p. 153).
Comment (Deposit): Model Name = Schist-hosted gold-quartz vein
