Deposit originally staked in 1925 or 1926; more claims staked in 1928; restaked as part of Marmot group in 1969. Site is in Misty Fiords National Monument.
Location: The Edelweiss prospect, which was restaked in 1969 as part of the Marmot group of 51 claims (BC019), is approximately located on the boundary of Sections 25 and 26, on the southeast side of Banded Mountain at an elevation of about 4500 feet (Berg and others, 1977, p. 110 and plate 2; Elliott and Koch, 1981, p. 9, loc. 20). This location is accurate to within about a quarter of a mile.
Geology: The country rocks in the general area of the Edelweiss prospect are recrystallized tuffaceous graywacke, slate, quartzite[?], and minor limestone of the Jurassic or older Mesozoic Hazelton Group (Buddington, 1929, p. 101; Berg and others, 1977, p. 15-17; Koch, 1996). The deposit consists of a quartz fissure vein about a foot thick that cuts metagraywacke and contains pyrite, pyrrhotite, and galena. A picked sample of the vein assayed 1.6 oz Au and 10.2 oz Ag per ton (Buddington, 1929, p. 110). Select grab samples collected by the U.S. Bureau of Mines in 1972 (Berg and others, 1977, p. 110-113) showed up to 15000 ppm Pb and 300 ppm Ag, but no gold.
Workings: Explored by an open cut, now partly caved. A picked sample (Buddington, 1929, p. 110) of the vein assayed 1.6 oz Au and 10.2 oz Ag per ton. Samples collected in 1972 (Berg and others, 1977, p. 110-113) showed up to 15000 ppm Pb and 300 ppm Ag, but no gold.
Alteration: Local intense iron staining.
