... tributaries do not, and probably never have, supported significant aquatic life. The Bonnifield mining district includes 26 known VMS prospects ( Newberry et al . 1997 ). The prospects occur within a greenschist-facies assemblage of metavolcanic and metasedimentary rocks included in the Yukon–Tanana...
