|Location and accuracy||The location of this occurrence is only known approximately to be about midway between Waterfall Cove in Slocum Arm and Fick Cove in the South Arm of Hoonah Sound. For this record, the site is plotted 0.2 mile southeast of the center of sec. 33, T. 49 S., R. 60 E. The location of this occurrence may be several miles or more from the coordinates given here. It is location P-88 of Bittenbender and others (1999) and MAS no. 0021140306 (U.S. Bureau of Land Management, 2002).|
Johnson and Karl (1975) map the rocks in the area of this occurrence as Triassic(?) greenstone intruded by northwest-trending, elongate stocks of Cretaceous or Jurassic gabbro and tonalite. The rocks are cut by steeply-dipping, mainly northwest-striking faults; these include the regional-scale Border Ranges Fault whose trace is about a mile southwest of this occurrence.Bittenbender and others (1999), citing Kimball (1982), describe the occurrence as a disseminated sulfide deposit in schist and gneiss, near the contact between Triassic(?) greenstone and marble. Samples of pyrite- and pyrrhotite-bearing schist and gneiss assayed up to 360 parts per million (ppm) copper and 1,600 ppm zinc.
