The Rob Roy 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 (Workings): Workings / Exploration = Workings consisted of a 100 foot shaft and 170 feet of drifts on two levels (Brooks, 1916; B 649).
Comment (Production): Production Notes = A small amount of ore was customed milled but production figures are not known (Brooks, 1916; B 649).
Comment (Reference): Primary Reference = Brooks, 1916 (B 642)
Comment (Deposit): Model Name = Gold and stibnite in quartz shear zones.
Comment (Geology): Geologic Description = High grade gold mineralization occurs in a shear zone 30 feet wide that strikes N 60 W. The shear exhibits two mineralized zones that contain quartz with pyrite, gold and stibnite, as well as irregular or kidney-shaped pods of stibnite (Brooks, 1916; B 649). Intrusive breccia was noted to be present on the dump of the Rob Roby shaft (Pilkington, 1970). A small amount of ore was custom milled from a 100-foot shaft with 170 feet of drifts (Brooks, 1916; B 649). Operation were suspended in mid-1918 because of excess water in the workings (Martin, 1920).
Comment (Exploration): Status = Inactive
