Several pyritic massive sulfide deposits have been recognized in an Ordovician-Silurian volcano-plutonic complex in the southern Prince of Wales Island region (Fig. 1). These deposits have been studied as part of a U.S. Geological Survey-California Institute of Technology investigation into the geologic and mineralization history of southern Prince of Wales Island (south of 55° North Latitude; Fig. 1). This report describes the geologic setting of the deposits and presents preliminary chemical analyses of the mineralization.
