A long-running fight between distressed debt investors is threatening to scuttle the reopening of the only U.S. mine producing rare metals used in hybrid electric cars and some military hardware.

A court-appointed trustee for bankrupt Molycorp Minerals LLC will ask a judge Friday to approve the sale of the last remaining assets associated with a rare-earth mine at Mountain Pass, California. But a lawsuit over mineral rights and complaints by the losing bidder for those assets are complicating efforts to reopen the mine.
