Edelweiss

The Edelweiss is a silver, gold, and lead mine located in Alaska.

About the MRDS Data:

All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments

Comment (Exploration): Status = Inactive

Comment (Deposit): Other Comments = 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.

Comment (Deposit): Model Name = Polymetallic veins

Comment (Workings): Workings / Exploration = 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.

Comment (Reference): Primary Reference = Berg and others, 1977

Comment (Geology): Geologic Description = 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.
