The Ross-Adams Mine is a uranium mine located in Alaska at an elevation of 951 feet.
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.

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.

Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Comments
Comment (Deposit): ORE BODY IS A FUSIFORM SHAPED AREA OF MINERAL CONCENTRATION WITHIN IGNEOUS INTRUSION. ORE MINERALS ARE IN VEINLETS AND DISSEMINATIONS WITHIN THIS BODY.
Comment (Workings): MINING FROM AN OPEN PIT AT FIRST. UNDERGROUND WORKINGS MAY HAVE BEEN DEVELOPED LATER
Comment (Commodity): LIST OF MINERALS IS PARTIAL
Comment (Production): ORE WAS EQUALLY RICH IN THORIUM, BUT EXTRACTION METHODS WERE TOO COSTLY AND THORIUM WAS NOT RECOVERED
Comment (Development): EXPLORATION HAS CONTINUED THROUGH 1982, BUT URANIUM PAKES ARE TOO LOW FOR MINING.
Comment (Reserve-Resource): ADITIONAL RESERVES AND RESOURCES HAVE BEEN DISCOVERED IN PLATE 1970'S, BUT TONNAGE AND GRADE ARE UNNAVAILABLE
