The Campbell and Boedeker 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 (Deposit): Model Name = High-sulfide auriferous quartz vein.
Comment (Geology): Age = Late Cretaceous or younger.
Comment (Reference): Primary Reference = Tuck, 1938
Comment (Workings): Workings / Exploration = A 20-foot tunnel did not penetrate weathered zone but did give good exposure of vein and host rock. A sample of sulfide concentrates assayed 1.9 ounces of gold per ton and 1.5 ounces of silver per ton. A sample of the sheared and pyritized diorite assayed 0.18 ounces of gold per ton (Tuck, 1938).
Comment (Geology): Geologic Description = The Campbell and Boedecker prospect explores one of several mineral deposits in a belt south of Valdez Creek. The Valdez Creek area is underlain by pre-Upper Triassic pelitic clastic rocks, minor tuff, limestone lenses, and conglomerate. The rocks apparently vary abruptly in regional metamorphosed grade, from prehnite-pumpellyite through greenschist and amphibolite, to granulite. These rocks are intruded by Upper Jurassic alkali gabbro and by dioritic intrusions of Late Cretaceous and Early Tertiary age (Smith, 1981).? the bedding and foliation of the strata strike about N 75 E and dip steeply northwest. Strike-slip faults having a similar orientation are also present, particularly on the south side of Valdez Creek (Smith, 1981). On the north side of the creek, a northwest-dipping thrust fault in part explains an apparent 'telescoping' of the metamorphic rocks.? the deposit consists of two-foot-thick auriferous quartz vein that cuts sheared and locally pyritized diorite. The vein contains up to 50% pyrite; it strikes N 85 E and dips 68 N. A sample of sulfide concentrates assayed 1.9 ounces of gold per ton and 1.5 ounces of silver per ton. A sample of the sheared and pyritized diorite assayed 0.18 ounces of gold per ton (Tuck, 1938).
Comment (Exploration): Status = Inactive
