The Booshu Camp is a molybdenum 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 (Reference): Primary Reference = Patton and Csejtey, 1971 (PP 684-C)
Comment (Workings): Workings / Exploration = Results of channel sampling here included (1) 3 feet of 0.71 % MoS2, (2) 6 feet of 0.28 % MoS2, and (3) 15 feet of 0.17 % MoS2 (Anderson, 1947, p. 36). Three grab samples of mineralized quartz monzonite contained 150, 700, and 1,000 ppm molybdenum and 300, 10, and 30 ppm copper respectively (Patton and Csejtey, 1971, p. C8).
Comment (Geology): Age = Mid-Cretaceous, the age of the host Sevuokuk pluton (108 +/- 3.2 Ma; Patton and Csejtey, 1980).
Comment (Geology): Age = Chron age is for Host Rock.
Comment (Exploration): Status = Inactive
Comment (Deposit): Other Comments = Locality 6 (West Cape) of Cobb (1972) should be deleted (Cobb, 1980, p. 51) as the cited reference information (Anderson, 1947, p. 35-36) is for the Booshu Camp site and not West Cape.
Comment (Geology): Geologic Description = Molybdenite mineralization here is in the Sevuokuk pluton, a mid-Cretaceous (108 +/- 3.2 Ma) composite body that includes biotite hornblende quartz monzonite and biotite quartz monzonite phases (Csejtey, Patton, and Miller, 1971; Patton and Csejtey, 1980). At this site, molybdenite occurs as disseminations and as scaly fracture and joint coatings (Anderson, 1947, p. 35-36) in biotite quartz monzonite. Small amounts of chalcopyrite and pyrite locally accompany the molybdenite. The mineralization appears to be concentrated in a zone along the shoreline between major joints. Results of channel sampling here included (1) 3 feet of 0.71 % MoS2, (2) 6 feet of 0.28 % MoS2, and (3) 15 feet of 0.17 % MoS2 (Anderson, 1947, p. 36). Three grab samples of mineralized quartz monzonite contained 150, 700, and 1,000 ppm molybdenum and 300, 10, and 30 ppm copper respectively (Patton and Csejtey, 1971, p. C8). Alteration is restricted to small amounts of quartz (at least some in veins) and partial sericitization of feldspars (Patton and Csejtey, 1971, p. C8 and C10).
Comment (Deposit): Model Name = Fracture fillings and disseminations of molybdenite in granitic rock. Deposit model 21b (?); porphyry Mo, low-F
