Casablanca's Nominees, Including Proposed Executive Chairman Lourenco Goncalves, Lack Crucial Industry Experience Needed to Navigate Today's Volatile Pricing Environment

Cliffs' Nominees Have the Right Experience to Drive Long-term,Sustainable Growth and Shareholder Value


Recommends Shareholders Vote WHITE Proxy Card Today

CLEVELAND - July 7, 2014 - Cliffs Natural Resources Inc. (NYSE: CLF) today issued the following letter to shareholders in connection with its upcoming 2014 Annual Meeting of Shareholders scheduled to be held on July 29, 2014:

Dear Fellow Cliffs Shareholder,

Cliffs' Annual Meeting of Shareholders is fast approaching and your vote is extremely important. Your Board of Directors is focused on driving value for all shareholders and continuing to position Cliffs for long-term, sustainable growth.

Your Board urges you to vote the enclosed WHITE proxy card "FOR" Cliffs' nine highly qualified and experienced nominees: Gary B. Halverson, Barry J. Eldridge, Mark E. Gaumond, Susan M. Green, Janice K. Henry, Stephen M. Johnson, James F. Kirsch, Richard K. Riederer and Timothy W. Sullivan.

By using the WHITE proxy card and voting as recommended by your Board, you will help prevent Casablanca from electing a majority slate and breaking up your Company.

When casting your vote, we ask that you strongly consider the following points:

· Cliffs' reconstituted Board and new management team are highly qualified and have the experience and fresh perspective necessary to lead the Company through a volatile iron ore and met coal price environment;

· Cliffs took decisive action to fundamentally shift the strategic, operational and financial direction of the Company in response to a volatile pricing environment in July 2013 - long before Casablanca owned a single share of Cliffs' common stock;

· Cliffs is prudently maintaining balance sheet strength and optimizing its portfolio to preserve value for shareholders as markets recover;

· We believe that Casablanca's nominees lack the collective experience necessary to lead the strategy of a mining company in today's challenging operating environment; and

· We believe that Casablanca has a short-term plan to sell off Cliffs assets in an industry-wide cyclical downturn, which would be value destructive for all other Cliffs shareholders.

Further, the Cliffs Board has determined that, following the completion of the Annual Meeting, the new Board will elect a different Chairman of the Board.  By voting for ALL of Cliffs nominees, more than half of Cliffs eleven-person Board will have been elected in 2013 or later and will include a new Chairman as well as two directors nominated by our shareholders.

CASABLANCA INSISTS ON WAGING A COSTLY AND DISTRACTING PROXY CONTEST DESPITE SETTLEMENT OVERTURES

Cliffs has continued to offer Casablanca reasonable settlement proposals, each of which demonstrates Cliffs' willingness to reach a compromise that provides additional shareholder representation on the Board and resolves a costly and distracting proxy contest.  However, Casablanca has refused to accept any of Cliffs' settlement offers to date.  Under Cliffs' latest settlement offer made on July 2, 2014, Casablanca would receive three seats on a reconstituted Cliffs Board consisting of nine directors in the aggregate (reduced from the current 11).  This would provide Casablanca with one-third of the Board and a voice in selecting a different Chairman of the Board, despite its ownership of only one-twentieth of the Company's shares outstanding. 

Despite Cliffs' good faith attempts to reach a compromise, Casablanca continues to seek a majority of your Board through its slate of nominees - the torchbearers of what we strongly believe to be an ill-conceived and value-destructive plan. We believe that the reason for Casablanca's stubbornness on this point is clear: Casablanca is fixated on the executive chairman role for Mr. Goncalves so that he can enact their self-interested, value-destructive plan to liquidate assets during an industry-wide cyclical downturn. 


CASABLANCA'S SLATE LACKS THE COLLECTIVE EXPERIENCE  NECESSARY TO DRIVE THE STRATEGY OF A CYCLICAL MINING  COMPANY LIKE CLIFFS


Casablanca's director nominees lack the collective experience we believe is necessary to lead the strategy of a mining company.

Furthermore, with Casablanca's abrupt announcement that Patrice Merrin withdrew from Casablanca's slate, Casablanca no longer offers any candidates with recent mining experience.  Ms. Merrin was one of the only Casablanca nominees with relevant leadership experience in the mining sector, making her departure disproportionately damaging to the already weak Casablanca slate. 

Ms. Merrin's replacement, James Sawyer, appears to us to be a last-minute attempt to fill an unexpected vacancy in Casablanca's unstable slate of unqualified candidates.  The choice of Mr. Sawyer is a curious one - he has no relevant industry or operational experience and no public company Board experience.

Also among the dissident's nominees is Mr. Goncalves, who Casablanca is proposing as executive chairman. Mr. Goncalves has no meaningful experience managing large-scale, long-lived mining assets in complex ore bodies or operating global assets in multiple geographies.  His metals industry experience has largely been with processing and distribution businesses with low fixed cost structures, limited commodity price exposure and low capital intensity. Mr. Goncalves' most recent experience was at Metals USA, a company Casablanca describes as a "manufacturer and processor of steel and other metals." According to Casablanca's June 26th investor presentation, Mr. Goncalves' most "recent" experience at a "mining company" was when he was an employee at Companhia Siderúrgica Nacional from 1981 - 1998.

In response to Casablanca's insistence that Mr. Goncalves be appointed as executive chairman of the Board, nine members of your Board interviewed Mr. Goncalves during March and April of 2014 regarding his qualifications to lead the Company and to understand his strategic vision for Cliffs.  Following these interviews, the Board determined that given Mr. Goncalves' lack of meaningful experience in managing large-scale, long-lived mining assets in complex ore bodies or operating global assets in multiple geographies, it was not in the best interests of Cliffs' shareholders to appoint him as executive chairman.

Cliffs needs and has in our new CEO Gary Halverson, a steady and experienced hand at the helm to navigate this volatile industry environment. Now is not the time to empower an unproven activist investor seeking to implement an irresponsible plan designed for short-term gains. We believe that Casablanca's notion of "fixing" Cliffs is ill-conceived and short-sighted, driven by their self-serving agenda.  

CLIFFS' NOMINEES HAVE THE EXPERIENCE NECESSARY  TO SUCCESSFULLY LEAD CLIFFS

In stark contrast to Casablanca's slate, Cliffs has assembled a strong Board that is well matched to the opportunities and challenges faced by Cliffs and the entire industry.  As evidenced below, we believe Cliffs' nominees are highly qualified to lead Cliffs through a volatile iron ore and met coal pricing environment.

Four of these directors are recent additions to the Board, carefully selected to help fundamentally shift the strategic, operational and financial direction of the Company in response to a volatile iron ore and met coal price environment.  These highly qualified directors help ensure Cliffs has the right experience and leadership expertise, including in mining, steel, basic materials, finance, engineering and natural resources businesses - the skills that your Board believes are required in order to understand and lead Cliffs.

Remember: By voting for ALL of Cliffs nominees, more than half of Cliffs eleven-person Board will have been elected in 2013 or later and will include a different Chairman as well as at least two new directors nominated by our shareholders.

VOTE THE WHITE PROXY CARD TODAY

Your vote is extremely important, no matter how many or how few shares you own. 

The Cliffs Board recommends shareholders vote today by telephone, by Internet, or by signing and dating the enclosed WHITE proxy card to vote "FOR ALL" of the Company's nine highly qualified and experienced director nominees with expertise in leading mining, steel, basic materials, engineering and natural resources businesses: Gary B. Halverson, Barry J. Eldridge, Mark E. Gaumond, Susan M. Green, Janice K. Henry, Stephen M. Johnson, James F. Kirsch, Richard K. Riederer and Timothy W. Sullivan.
