|Location and accuracy||The location of this (placer?) occurrence is known only approximately; it is on the northeast shore of Deep Bay, about 0.8 mile from the head of the bay. The occurrence is 0.2 mile west of the center of sec. 16, T. 51 S., R. 61 E. It is location P-97 of Bittenbender and others (1999) and MAS no. 0021140303 (U.S. Bureau of Land Management, 2002).|
Geologic descriptionJohnson and Karl (1985) map the rocks in the vicinity of this occurrence as part of a Tertiary(?) granodiorite stock. The stock contains roof pendants and inclusions of Mesozoic or Paleozoic amphibolite, gneiss, schist, and marble; the rocks are cut by high-angle, mainly northwest-striking faults. Bittenbender and others (1999), citing Kimball (1982), report that a stream-sediment sample at this site contained 12 parts per million gold, but that no gold was found in other samples.
