Kerrey joins board of rare-earths exploration firm

LINCOLN, Neb. (AP) -- Former U.S. Sen. Bob Kerrey has joined the board of a rare-elements exploration company.

U.S. Rare Earths, Inc., announced Monday that Kerrey, also former governor of Nebraska, will sit on its board of directors.

The Arkansas-based company holds mining claims in Idaho, Montana and Colorado.

The company seeks rare elements that are used in clean-energy technologies, such as hybrid cars and electric vehicles. The elements also have applications in computer hard drives, fiber optics, lasers, cellphones and digital music players.

The company says it wants to create a domestic U.S. supply for the materials to reduce the world's current dependence on China.
