The Unnamed (west-northwest of Mt. Dagelet) is a titanium 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 (Deposit): Other Comments = the site is in Glacier Bay National Park and Preserve.
Comment (Deposit): Model Name = Possibly Bushveld Fe-Ti-V (Cox and Singer, 1986; model 3). Magmatic segregation; ilmenite deposit in layered mafic-ultramafic intrusive.
Comment (Reference): Primary Reference = Rossman, 1963 (B 1121-F)
Comment (Workings): Workings / Exploration = There are no workings. Sample 53ARm a37 contained 25 percent ilmenite (Rossman, 1963, p. F43).
Comment (Geology): Geologic Description = This occurrence consists of ilmenite segregations in the Crillon-La Perouse layered mafic-ultramafic intrusion, along its southwestern contact zone (Brew and others, 1978). The adjacent metamorphic rocks are hornblende and biotite schist probably derived from a Mesozoic protolith. The intrusion is of Tertiary age.? An ilmenite magmatic segregation deposit exists at the site. It continues along strike of the layered intrusion for several hundred feet but could not be traced farther because of extremely steep topography. At the site, the intrusion is estimated to contain from 10 to 25 percent ilmenite (Rossman, 1963, 1121-F). A sample that contained 25 percent ilmenite contained 2 percent graphite by weight.
Comment (Reserve-Resource): Reserves = An inferred resource could be calculated based on data given by Rossman.
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Tertiary.
