The Peace River Placer Occurrence is a uranium, thorium, and bismuth 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.

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.

Comment (Development): SAMPLES COLLECTED IN 1947 AND 1951.
Comment (Geology): SMALL SATELLITIC SYENITIC STOCK OF GRANITE MTN. PLUTON (CRETACEOUS) INTRUDED ANDESITIC VOLCANIC ROCKS (JURASSIC(?) - CRETACEOUS)). ; REG.COM: MINERAL ASSOCIATIONS SUGGEST THAT THE URANIUM MINERALS ARE DERIVED FROM A SULFIDE BEARING LODE (POSSIBLY A VEIN) RATHER THAN OCCURRING AS ACCESSORY MINERALS IN THE GRANITIC ROCK OF GRANITE MTN.
