|Location and accuracy||As described by Buddington (1929), this prospect is about 1.5 mile north-northeast of the mouth of Scenery Cove and just east of the tidal flat below the toe of the Baird Glacier. It is described as in a steep gully in this vicinity by Roehm (1945 [IR 195-37]). It is in the SE1/4 section 14, T. 55 S., R. 79 E. The prospect could not be found by Still and others (2002).|
Geologic descriptionAs described by Roehm (1945 [IR 195-37]), this prospect is a fracture zone over 100 feet wide that strikes N 70 W along a steep gully. It is intersected by another fracture zone that strikes N 80 E. The rocks in the vicinity consist of Paleocene or Cretaceous quartz diorite (Gehrels and Berg, 1992). The fracture zones contain small quartz masses and veins up to 12 inches thick with pyrite, galena, sphalerite, chalcopyrite, arsenopyrite, and free gold. Roehm (1945 [IR 195-37]) noted that while the veins and quartz masses are locally rich, they are probably too few and too far apart to be an economic deposit. One sample contained 0.02 ounce of gold per ton and 1.50 ounces of silver per ton. Buddington (1923) indicated that fracture zone was 140 feet wide and averaged about 0.145 ounce of gold per ton; the richest part was about 5 feet wide and contained about 0.774 ounce of gold per ton. The prospect could not be found by Still and others (2002).
