Boedeker

The Boedeker is a lead and 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 (Workings): Workings / Exploration = Tuck (1934) reports several open cuts and a 30 foot adit were excavated at this site; the present condition is unknown.

Comment (Reference): Primary Reference = Tuck, 1934

Comment (Deposit): Model Name = Low-sulfide Au-quartz veins (Cox and Singer, 1986; model 36a).

Comment (Deposit): Other Comments = the prospect is located within Denali State Park.

Comment (Geology): Geologic Description = Steeply dipping Triassic foliated slate, fine-grained schist and argillite (Trvs, Reed and Nelson, 1980) are cut by one steeply dipping, three- to twelve-foot-wide quartz vein and smaller parallel quartz veins that range from 2 to 10 inches wide and strike N20W and dip 20W. The veins contain disseminated pyrite and arsenopyrite with trace amounts of silver and free gold. Gold is preferentially in smaller quartz veins, none of which extend more than 100 feet along strike. ? the mineralization may be related to the undivided Tertiary and (or) Cretaceous intrusive bodies (TKi) mapped by Reed and Nelson (1980) to the south of this occurrence. Geophysical and geological mapping by the Alaska Division of Geological and Geophysical Surveys which is currently ongoing (1997-1998) may provide more information in the near future.

Comment (Geology): Age = Tertiary or Cretaceous; mineralization may be related to the undivided Tertiary and (or) Cretaceous intrusive bodies mapped by Reed and Nelson (1980) the south of this occurrence.
