Cliffs Natural Resources Inc. published a news release on February 24, 2009 as follows:

Production Curtailments Announced at Hibbing Taconite and Northshore Mining
CLEVELAND, OH --February 24, 2009 --Cliffs Natural Resources Inc. (NYSE:CLF), today announced additional production curtailments and temporary facility shutdowns that will affect the Hibbing Taconite and Northshore Mining Company iron mining and pelletizing operations in Minnesota.

Hibbing Taconite: The owners of Hibbing Taconite Joint Venture have determined it necessary to further reduce pellet production by an additional 2.75 million tons in 2009. This production adjustment represents a 50% decrease from the mines original 2009 plan to produce 5.5 million tons. The reduction will be accomplished by idling a second of the facility’s three pelletizing furnaces at the end of March and then initiating a complete shutdown of the facility for approximately 15-weeks beginning in May.

With the production curtailment, it will be necessary to adjust employee headcount. In compliance with the U.S. Department of Labor’s Worker Adjustment and Retraining Notification (WARN) Act, notices have been sent to local government officials and the United Steelworkers. The WARN notices are necessary when there is a potential to lay off more than 50 employees for a period in excess of six months. Approximately 83 employees will receive the WARN notices, with layoffs commencing at the end of April.

Hibbing Taconite’s revised operating plan will utilize one pelletizing line from the end of March until May 16, at which time the facility will initiate a complete shutdown until August 31. Hibbing Taconite plans to restart one pelletizing line at the beginning of September, which will operate through the end of 2009 to reach the anticipated total pellet production of 2.75 million tons.

Hibbing Taconite has the potential to produce 8.3 million tons per year when operating at full rated capacity, and is jointly owned by subsidiaries of ArcelorMittal (62.3%), Cliffs Natural Resources (23%), and U.S. Steel Canada (14.7 %). Northshore Mining Company: A one-month production shutdown will occur during April. The curtailment will reduce production at Northshore to approximately 3.7 million tons in 2009. Northshore anticipates restarting its two larger pelletizing lines at the beginning of May.

Northshore Mining Company, a wholly-owned Cliffs Natural Resources’ subsidiary, has the capability to produce 5.8 million tons annually when operated at its full rated capacity.

"Today’s announcement reflects the continuing difficult economic conditions of the global steel and iron ore industry," said Donald J. Gallagher, Cliffs’ President-North American Business Unit.

"The production adjustments announced today at Hibbing Taconite and Northshore Mining reflect reduced planned blast furnace operations by our steel company partners and customers. The actions being taken are necessary to balance mine production with demand."
