The Tungsten Hill 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 = By 1916, several zones that contained scheelite were located. On the Grand Duke Nikolas claim, a scheelite lode in schist was exposed in an open cut. On the Tungsten No. 1 claim, another open cut had been made in schist and quartzite schist that included a zone with scheelite. The width of the mineralized zone was not apparent. On the General Joffre claim, a lode 14 feet wide with scheelite has been exposed. This deposit as a whole was considered low-grade ore (Mertie, 1917, p. 422-424). In 1943, Joesting (1943 [ATDM Pamph. 2]) reported that little work had been done since 1918.
Comment (Reference): Primary Reference = Mertie, 1917
Comment (Deposit): Model Name = W skarn deposit (Cox and Singer, 1986; model 14a)
Comment (Geology): Geologic Description = By 1916, four zones as much as 14 feet wide that contained scheelite had been discovered on the western periphery of a large granite body (Mertie, 1917, p. 422-424). Scheelite occurs in tactite, silicified limestone, granite and pegmatitic dikes, and in small quartz veins in schist (Berg and Cobb, 1967). Samples of high-grade ore on the dump assayed 8percent tungsten trioxide (WO3) (Joesting, 1943 [ATDM Pamph. 2]). This prospect is near the contact of a Cretaceous porphyritic granite and Fairbanks Schist that consists of quartz-muscovite schist, quartzite, and chloritic-quartz schist (Newberry and others, 1996).
Comment (Exploration): Status = Inactive
Comment (Production): Production Notes = No record of production.
