Bush

The Bush is a molybdenum and lead 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 (Geology): Age = If the Bush prospect represents a porphyry Mo occurrence, its age is probably Late Cretaceous to early Tertiary, since there are other porphyry Mo deposits in the area of that age (Mosquito: TC015).

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

Comment (Workings): Workings / Exploration = In 1979, WGM Inc. analyzed the ridgetop soils, and in 1981 Arctic Resources Inc. conducted soil sampling on a grid. In 1982, Doyon Ltd. conducted prospecting traverses on the property.

Comment (Geology): Geologic Description = Geology in the immediate vicinity of the Bush prospect consists of one rhyolite and two porphyritic latite units intruding Precambrian to Paleozoic amphibolite-grade schist (Foster, 1976, Doyon Ltd., 1998). The rhyolite is highly siliceous and iron stained along fracture surfaces; hematite and pyrite are common trace accessory minerals. One porphyritic latite unit is light green and contains trace amounts of pyrite; the other unit lacks pyrite and is a darker green (Dashevsky, 1982). The region where the prospect is located lies within the Yukon-Tanana Y1 subterrane (Foster, 1970; Foster and others,1994). During soil sampling programs, low levels of lead and molybdenum were identified (Doyon Ltd., 1998).

Comment (Deposit): Model Name = Porphyry Mo? (Cox and Singer, 1986; model 21a)

Comment (Deposit): Other Comments = This property lies on Doyon Ltd. selected land. For more information, contact Doyon Ltd. This property may be the same as the Hajdukovich molybdenum prospect reported by Saunders (1967), or very close to it.

Comment (Exploration): Status = Active
