Sixtymile Butte

The Sixtymile Butte is a gold 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 = Active

Comment (Geology): Age = the volcanic complex probably is mid-Cretaceous (Doyon, 1998).

Comment (Reference): Primary Reference = Doyon Ltd., 1998

Comment (Workings): Workings / Exploration = In 1975, WGM Inc. conducted a base-metal reconnaissance program. In 1981, Arctic Resources Inc. did a soils traverse, and in 1985 Doyon Ltd. resubmitted the samples for Au pathfinders. In 1990, Doyon Ltd. sampled stream sediments for gold.

Comment (Deposit): Model Name = Epithermal Au-Ag?

Comment (Deposit): Other Comments = This property is located on Doyon conveyed land. For more information, contact Doyon Ltd.

Comment (Geology): Geologic Description = The Sixtymile Butte area is dominated by mid-Cretaceous lavas, welded tuffs, tuff breccias and volcanic agglomerates (Foster, 1970). These rocks were mapped as Tertiary, but recent work suggests that they are Cretaceous (Doyon Ltd., 1998). The volcanics range in composition from andesitic to dacitic and have volcanic-arc-type, minor-element abundances (Bacon and others, 1990). Stream-silt sampling revealed three drainages with anomalous gold values (Doyon Ltd., 1998).
