LINCOLN, Nebraska (AP) - A University of Nebraska-Lincoln hydrogeologist is mapping the Ogallala Aquifer to find deep uranium formations.
The Crow Butte mine near Crawford has produced 16 million pounds of uranium since 1991. Steven Sibray is mapping the aquifer in the Nebraska Panhandle south of the mine to find more stores of the mineral.
Sibray says the mapping can help mining companies find deep uranium-bearing sandstones.
So far, his research shows the potential for deep formations at the base of the White River group in the southern Panhandle.
The mapping is part of a larger project to define the hydrogeologic framework of the aquifer.
