Cliffs Natural Resources Inc. Announces Temporary
Production Halt At Its West Virginia Coal Operations

CLEVELAND — Jan. 30, 2009 — Cliffs Natural Resources Inc. (NYSE: CLF) announced that its wholly owned subsidiary, Pinnacle Mining Company, LLC ("Pinnacle"), will temporarily halt production at its Pinnacle Mine Complex. Plans call for the production shutdown, which will affect approximately 360 employees, to begin Monday, Feb. 2, and run through Feb. 28. Cliffs indicated the 2009 production plan at the Pinnacle Complex called for the mines to produce approximately 85,000 tons in February. Mine management met Friday afternoon with local leadership of the United Mine Workers of America to notify them of the production curtailment.

The Pinnacle Complex, which is located near Pineville, WV, includes the Pinnacle and Green Ridge # 1 and Green Ridge # 2 mines and the Pinnacle Preparation Plant. The Pinnacle and Green Ridge #1 mines both will halt production during February, while the prep plant will operate on a reduced schedule to serve customer requirements. The Green Ridge # 2 mine was previously idled.

Pinnacle produces metallurgical coal for the steel industry. Metallurgical coal demand has been reduced as the steel industry has cut back production in the face of the global economic slowdown.

"The month-long production curtailment at Pinnacle is necessary to balance our production and inventory with customer demand," said Duke Vetor, senior vice president, Cliffs North American Coal.
