Cliffs Natural Resources Inc. Closes Wabush Mines Acquisition

CLEVELAND – Feb. 1, 2010 – Cliffs Natural Resources Inc. (NYSE: CLF) (Paris: CLF) today announced that it has completed the acquisition of its former partners’ interests in the Wabush Mines joint venture for approximately $88 million.

Cliffs announced in October 2009 that it would exercise its right of first refusal to acquire U.S. Steel Canada's 44.6% interest and ArcelorMittal Dofasco's 28.6% interest. With the closing of the acquisition, Cliffs now owns 100% of the operation that it has managed since 1965. The Wabush Mines operation includes the Scully Iron Ore Mine near Wabush, Newfoundland, Labrador; the pellet plant and port facilities at Point Noire, Quebec; and integrated rail facilities.

With this transaction, Cliffs adds more than 50 million tons of iron ore reserves and approximately four million tons of incremental iron ore pellet production capacity with access to the seaborne market.

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: changes in demand for iron ore pellets by North American or international integrated steel producers, or changes in 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; availability of capital equipment and component parts; availability of float capacity on the Great Lakes or for seaborne markets; 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; the impact of consolidation in the steel industry; 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; 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 and employee benefit costs; 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 the 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.
