These prospects are in the South Prince of Wales Wilderness which is closed to prospecting and mineral exploration.
Location: The location of the R. and L. Group of four claims is well documented. It is on the northeast shore of the head of Hunter Bay, near the northeast corner of section 8, T. 81 S., R. 88 E. The Goodhope prospect is about 0.5 mile away in an uncertain direction. The location of the R. and L. Group is accurate.
Geology: The R. and L. Group consists of four claims. Wilcox (1937) described the country rock as greenstone; Gehrels (1992) identified the rocks in the vicinity as basaltic and andesitic volcanic rocks with a narrow band of northwest-trending limestone, all part of the Silurian or Ordovician Descon Formation. The mineral deposits are in and adjacent to fault zones (Wilcox, 1937). At the No. 2 claim, a minor fault zone with calcite stringers and some pyrite is exposed for about 60 feet. A sample contained only a trace each of gold and silver. A 6-foot sample of outcrop mineralized with magnetite and pyrite at the No. 3 claim contained 0.2 ounce of gold per ton and a trace of silver. Chapin (1916) provides the only description of the deposit at the Goodhope prospect, which Wilcox (1937) places about a half mile from the R. and L. Group. The Goodhope prospect consists of irregular masses of magnetite, chalcopyrite, and pyrite in quartz veins in greenstone near a contact with granitic rocks.
Workings: The only workings are a 40-foot adit on the Goodhope prospect. Several claims were staked in the area in the late 1930's.
