Anikovik River

The Anikovik River is a chromium, gold, and tin 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 = Quaternary

Comment (Deposit): Model Name = Alluvial tin placer (Cox and Singer, 1986; model 39e)

Comment (Geology): Geologic Description = Anikovik River's eastern tributaries have headwaters in Ordovician limestone of the York Mountains (Sainsbury, 1972) whereas the main drainage and western tributaries are in areas underlain by a thin-bedded, slaty metapelitic and metasandstone sequence of unknown but probable Paleozoic age locally intruded by altered mafic bodies. The USBM completed three churn-drill holes in a line across Anikovik River at this locality (Mulligan, 1959). Heavy mineral concentrates from the five feet of gravel encountered here contained chromite (in one hole; 0.23 pounds of chromite per cubic yard containing 48 % Cr2O3), pyrite, limonite pseudomorphs after pyrite, olivine, augite, apatite, cassiterite, and gold. The gravels contain only a trace of tin.

Comment (Workings): Workings / Exploration = Thre USBM churn-drill holes were completed here (Mulligan, 1959).

Comment (Reference): Primary Reference = Mulligan, 1959 (USBM RI 5520)

Comment (Exploration): Status = Inactive
