Cliffs Natural Resources Inc. Provides WARN Notices

CLEVELAND — Nov. 6, 2008 — Cliffs Natural Resources Inc. (NYSE: CLF) today reported that in anticipation of potentially necessary production curtailments, its North America business unit has initiated compliance with the U.S. Department of Labor’s Worker Adjustment and Retraining Notification (WARN) Act, by notifying local officials and the United Steelworkers in four operating locations of the potential for production curtailments and employee reductions.

WARN Act notification is required 60 days in advance under certain circumstances when there is a potential for layoffs of more than 50 employees for a period in excess of six months.

The operations that could be affected are the Empire and Tilden mines in Michigan and the Hibbing Taconite and United Taconite mines in Minnesota.

Production curtailments at United Taconite were previously announced on Oct. 28, 2008. United Taconite and local USW leadership have since agreed to implement a 32-hour workweek through the end of January in order to avoid layoffs. A potential layoff at the end of January may be delayed or avoided if the 32-hour workweek is extended past the end of January.

"Any production curtailments at our partnership mines are subject to approval by the mine partners, and as a result no final decisions have been made for Tilden, Empire, and Hibbing," said Donald J. Gallagher, president of Cliffs’ North American business unit. "However, we must acknowledge that there is a potential for curtailments and layoffs and make the proper notifications for our employees and the community."

"It is unfortunate that this is necessary," Gallagher continued, "but we have seen a reduction in blast furnace operations by our customers due to the downturn in the global economy. As a result, their pellet needs have significantly declined. Any actions we take going forward will be necessary to balance mine production and pellet inventories with customer demand."

The Empire and Tilden mines have a combined capacity to produce more than 13 million tons of pellets annually. Hibbing Taconite and United Taconite have annual production capacities of 8 million tons and more than 5 million tons, respectively.

This news release contains predictive statements that are intended to be made as "forward-looking" within the safe harbor protections of the Private Securities Litigation Reform Act of 1995. Although the Company believes that its forward-looking statements are based on reasonable assumptions, such statements are subject to risk and uncertainties.

Actual results may differ materially from such statements for a variety of reasons, including: the length and extent of any potential production curtailments; changes in the sales volumes or mix; the impact of other price-adjustment factors on the Company's sales contracts; changes in demand for iron ore pellets by North American integrated steel producers, or changes in Asian iron ore demand due to changes in steel utilization rates, operational factors, electric furnace production or imports into the United States and Canada of semi-finished steel or pig iron; the impact of consolidation and rationalization in the steel industry; availability of capital equipment and component parts; availability of float capacity; changes in the financial condition of the Company's partners and/or customers; rejection of major contracts and/or venture agreements by customers and/or participants under provisions of the U.S. Bankruptcy Code or similar statutes in other countries; events or circumstances that could impair or adversely impact the viability of a mine and the carrying value of associated assets; inability to achieve expected production levels; reductions in current resource estimates; failure to receive or maintain required environmental permits; problems with productivity, labor disputes, weather conditions, fluctuations in ore grade, tons mined, changes in cost factors including energy costs, transportation, mine closure obligations and employee benefit costs; the ability to identify, acquire and integrate strategic acquisition candidates and the effect of these various risks on the Company's future cash flows, debt levels, liquidity and financial position.

Reference is also made to the detailed explanation of the many factors and risks that may cause such predictive statements to turn out differently, set forth in the Company's Annual Report and Reports on Form 10-K and previous news releases filed with the Securities and Exchange Commission, which are publicly available on Cliffs Natural Resources' website. The information contained in this document speaks as of the date of this news release and may be superseded by subsequent events.
