Scarp

The Scarp is a gold and silver 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.

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 (Geology): Age = Eocene or younger.

Comment (Reference): Primary Reference = Peterson and others, 1982

Comment (Deposit): Other Comments = This site is on land selected by the Aleut Corporation.

Comment (Geology): Geologic Description = This occurrence is a 2,000- by 2,500- foot alteration zone in an area of slumped blocks of tuffs and flows. The rocks are part of the late Eocene to early Oligocene Popof volcanic rocks (Wilson and others, 1995). Mineralization consists of weakly auriferous quartz-marcasite-amethyst veins localized mostly along the margins of a slump block. The veins average 1.5 feet in width and can be traced for as much as 1,200 feet on strike. The veins generally are discontinuous, however, and do not seem to form a well -defined system (Peterson and others, 1982). The wall rock marginal to the veins has been replaced by silica and pyrite. Argillic alteration is widespread throughout the area. Some of the country rocks have been completely replaced by clay and some by pervasive chlorite and pyrite. The mineralization may be controlled by a north-northwest-trending fracture zone that can be traced for approximately 2 miles. Fifteen grab samples contained as much as 0.975 ppm gold, 13 ppm silver, 66 ppm copper, 45 ppm lead, 175 ppm zinc, 1,000 ppm or more arsenic, and 4.75 ppm mercury (Peterson and others, 1982). Two samples collected by Battle Mountain Exploration Company in 1986 contained 0.032 and 0.038 ounce of gold per ton and as much as 4.7 ppm mercury.

Comment (Workings): Workings / Exploration = In 1982 UNC Teton Exploration Drilling Company mapped and sampled this occurrence. The samples contained as much as 0.975 ppm gold and 13 ppm silver.

Comment (Deposit): Model Name = Epithermal gold veins
