This locality has two parts, one on each side of the Pilgrim (Kruzgamepa) River, just downstream from the mouth of Iron Creek (SO127). They are separated by 1,000 feet of the Pilgrim River floodplain. The mineralization on the north side of the river consists of lenses of massive galena in marble near a contact with schist (Smith, 1908). One lens exposed over a distance of 3 feet in a prospect trench contain pyrite, finely crystalline galena, and minor sphalerite. A 2-foot sample across the highest-grade part contained 0.30 ounce of gold per ton, 2.3 ounces of silver per ton and 2.95 percent lead (Asher, 1969). Two samples reported by the owner contained 22.87 percent lead and 20.0 ounces of silver per ton and 14.2 percent lead and 14.5 ounces of silver per ton. The deposits on the south side of the river also include discontinuous lenses of massive galena. An 8- to 10-foot long, 6-foot wide,and 1.5-foot- thick lens of pyrite, fine galena, and limonite with siliceous marble, calcite, and quartz gangue was mined from a 25-foot-long adit and a few tons of ore were apparently shipped. Some boulangerite may also be present (Sainsbury and others, 1972). Pb-isotope analysis of one galena sample gave results identical to samples from the Red Dog (DL001) and Drenchwater Creek (DL002-004) deposits of the western Brooks Range (Church and others, 1985). The mineralization is preferentially developed in the marble but nearby quartz mica schist contains pyrite. The schist/marble contacts appear sheared (Cathcart, 1922). The massive galena is described as a replacement of the host marble (Smith, 1908).
