Comments
Comment (Reference): Primary Reference = Cox and others, 1989
Comment (Geology): Age = The disseminated sulfides are probably syngenetic with their Late Triassic host rocks.
Comment (Geology): Geologic Description = The country rocks in the area of the Cleopatra prospect include Upper Triassic, intensely deformed and metamorphosed, interbedded shale, argillite, sandstone, siltstone, and argillaceous limestone; and dikes, sills, and small plugs of altered diabase and gabbro (Wilson and others, 1998). These rocks in turn are intruded by Upper Cretaceous(?) and Lower Tertiary granite plutons. The deposit consists of stratabound disseminated chalcopyrite and pyrrhotite in the metasedimentary rocks.
Comment (Workings): Workings / Exploration = Rocks are stream-sediment sampling, ground EM and magnetic geophysical surveys were conducted in the mid-1970s (unpublished report for the New Alaska Syndicate, 1977).
Comment (Deposit): Model Name = Besshi massive sulfide (Cox and Singer, 1986; model 24b)
Comment (Exploration): Status = Inactive
