The Blossom 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 = The workings consisted of two shafts and 23 trenches and pits, all of which were caved by 1942 (Byers, 1957, p. 201). Dozer trenching took place in 1951 in an effort to expose scheelite mineralization (Williams, 1951).
Comment (Reference): Primary Reference = Cobb, 1976 (OFR 76-662)
Comment (Deposit): Model Name = W skarn deposit (Cox and Singer, 1986; model 14a)
Comment (Geology): Geologic Description = The Blossom tungsten prospect is along the western edge of a large mass of porphyritic granite that intrudes quartz-mica and amphibole schist. By 1918, a quartz stringer rich in scheelite was found in the bottom of a shaft in granite porphyry (Mertie, 1917). Another shaft 20 feet deep, opened a scheelite lode that was 3 to 4 feet thick (Mertie, 1917). Select samples from dumps contained 1.44 percent and 2.02 percent tungsten tri-oxide (WO3) (Byers, 1957). Mulligan (1974) characterized this prospect as containing pegmatite-type quartz-scheelite stringers that cut quartz-biotite schist and porphyritic granite. Workings consisted of two shafts and 23 trenches and pits, all of which were caved by 1942 (Byers, 1957, p. 201). Dozer trenching took place in 1951 in an effort to expose scheelite mineralization (Williams, 1951).
