The Franklin is a tungsten 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 = Surface trenches across the Ptarmigan and Franklin claims uncovered several mineralized zones (Chapin, 1919, p. 327).
Comment (Geology): Geologic Description = Surface trenches across the Franklin and Ptarmigan claims uncovered several mineralized zones approximately 15 to 20 feet wide that consist of quartz and silicates with scheelite (Chapin, 1919, p. 327). The lode strikes N. 40 E. and dips northwest. This prospect lies on the periphery of a Cretaceous granite and granodiorite that intrudes two units of the Fairbanks Schist that are composed of (1) quartz-muscovite schist, quartzite, and chlorite-quartz schist, and (2) amphibolite, magnetite-rich biotite schist, quartzose schist, and marble (Newberry and others, 1996).
Comment (Reference): Primary Reference = Chapin, 1919
Comment (Exploration): Status = Inactive
Comment (Deposit): Model Name = W skarn deposit (Cox and Singer, 1986; model 14a)
