Location: The Trepple H prospect is at an elevation of about 400 feet on the east side of Silver Bay, on an unnamed creek 0.3 mile north of the mouth of Bear Cove. The prospect is in the NE1/4 sec. 13, T. 56 S., R. 64 E. It is MAS no. 0021140161 (U.S. Bureau of Land Management, 2002). The location is accurate within 0.5 mile.
Geology: The rocks in the vicinity of this prospect are part of a Triassic and/or Jurassic unit that consists of biotite schist and gneiss with some amphibolite, quartzite, phyllite, and hornfels (Loney and others, 1975). The unit is a thermal aureole around a large Tertiary tonalite stock. Little is known about this prospect other than that it was staked for nickel (U.S. Bureau of Land Management, 2002). It is shown by name on a map in Bittenbender and others (1999) but is not listed or described in their report.
Workings: No information other than that a claim was staked here.
Age: Triassic or younger based on the age of the host rocks.
