Rapid River bend

The Rapid River bend is a uranium, lead, tin, and molybdenum 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 (Reference): Primary Reference = Barker (1981)

Comment (Geology): Geologic Description = Rubble of several phases of Old Crow batholith includes 2-mica granite, aplites and granodiorite. Area has hematite and secondary uranium minerals in quartz vein and brecia float, a radon gas anomaly, and associated rock and soil anomalies.

Comment (Deposit): Model Name = Lode; felsic plutonic-associated Sn, Mo, U, +W and base metals, possible veins, greisens and porphyry deposits.

Comment (Deposit): Other Comments = This area is just south and east of > 38.5 square mi (100 square km) of creek drainages containing variable to abundant cassiterite, monazite, ilmenite and allanite, and variable scheelite, powellite, molybdenite and chromite in sluice samples. Also, see MAS/MILS Sequence # 0020330009 (USBM, 1995)

Comment (Workings): Workings / Exploration = Sample of quartz vein float contain up to 2.8 ppm Ag, >2000 ppm B, 50 ppm Be, 70 ppm Bi, 280 ppm Cu, 70 ppm Mo, 3300 ppm Pb, 300 ppm Sn, 1600 ppm U and 1500 ppm Zn. Soil samples contain up to 3100 ppm Pb, 3100 ppm Zn and 120 ppm U (Barker, 1981, p.90-95).

Comment (Exploration): Status = Inactive
