Copper, Gold, Platinum, and Palladium Sample Results from the Klukwan Mafic/Ultramafic Complex, Southeast Alaska.
The Klukwan Mafic-Ultramafic complex, located near Haines in southeast Alaska, was examined by Bureau of Mines personnel in 1981- 82 to determine its potential for platinum-group metals, gold, and copper. The Ultramafic portion of the complex and the alluvial fan below have long been recognized as a significant iron deposit. During this examination, over 400 rock, panned concentrate, and stream sediment samples were collected from an area 9 miles long by about 3 miles wide. Analyses of the samples indicate interesting values in platinum, palladium, gold, and copper at a number of locations throughout the area. Some of these values are located on Bureau of Land Management land open to claim staking and the remainder are located on patented mining claims.
