|Location and accuracy||This occurrence is located near high tide level on the north side of Passage Canal, approximately a half-mile west of Logging Camp Bay. It is located in the NE1/4 section 31, T. 9 N., R. 6 E., of the Seward Meridian. This is location S-165 of Jansons and others (1984). This location is accurate to within a quarter of a mile.|
Geologic descriptionThis deposit consists of a gold- and molybdenite-bearing pegmatite vein hosted in the Passage Canal pluton. Lanphere (1966) has dated the Passage Canal pluton at 36.6 million years (Oligocene). The occurrence was discovered by the U.S. Bureau of Mines in 1981 (Hoekzema and Sherman, 1983). One grab sample of the felsic pluton contained 2.5 ppm gold, 150 ppm molybdenum, and 1,000 ppm bismuth.
