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 (Reference): Primary Reference = Grybeck and Nelson, 1981

Comment (Workings): Workings / Exploration = Grab sample collected during regional geologic mapping by the USGS in the late 1970s.

Comment (Geology): Age = Devonian or younger based on age of host rock.

Comment (Geology): Geologic Description = This occurrence consists of a grab sample of copper-stained, orange-weathering dark-gray stretched-pebble conglomerate collected from an otherwise monotonous and regionally extensive sequence of Devonian phyllite (Nelson and Grybeck, 1980; Grybeck and Nelson, 1981). The sample contained 5 ppm Ag and 1500 ppm Cu. No sulfides were noted in the sample, and the occurrence appeared to be only of local extent.

Comment (Deposit): Other Comments = the area is within the Gates of the Arctic National Park and Wilderness and has been closed to prospecting since 1981.

Comment (Exploration): Status = Inactive
