|Location and accuracy||This prospect(?) is at sea level at the south mouth of Fish Bay on northern Baranof Island. The prospect(?) is 0.4 mile north-northwest of the southeast corner of sec. 8, T. 52 S., R. 61 E. It is location P-104 of Bittenbender and others (1999) and MAS no. 0021140147 (U.S. Bureau of Land Management, 2002). The location probably is accurate within a mile.|
Geologic descriptionLoney and others (1975) map the rocks in the area of this prospect as a Jurassic tonalite stock that contains roof pendants or inclusions of undivided Mesozoic or Paleozoic, amphibolite, gneiss, schist, and marble. The prospect is at or near the contact between the tonalite and a metamorphic roof pendant. Bittenbender and others (1999) describe this prospect as an auriferous quartz vein; samples contained up to 0.45 ounce of gold per ton.
