Exhibit A

Casablanca Capital Files Investor Presentation Detailing Case for Fundamental Change at Cliffs

Urges Shareholders to Vote the GOLD Proxy and Elect Leadership Committed to Restoring Shareholder Value

New York – June 26, 2014 – Casablanca Capital LP (“Casablanca”), the beneficial owner of approximately 5.2% of Cliffs Natural Resources Inc. (NYSE: CLF), today released a detailed presentation outlining its plan to drive substantial value creation for all Cliffs shareholders. The presentation, along with other information regarding Casablanca’s nomination of six director candidates for election to the Board of Directors at the Company’s upcoming 2014 Annual Meeting of shareholders to be held on July 29, 2014, can be found at www.fixcliffs.com.

Donald Drapkin, Chairman of Casablanca, stated, “Cliffs’ Board supported an expansion strategy that destroyed over $9 billion of capital and drove the share price down by 85%. This Board continues to resist the fundamental change that is needed to get Cliffs back on track. The incompetence, inaction, misaligned compensation and self-interest must come to an end. We urge shareholders to elect a new slate of directors who will refocus Cliffs on its core U.S. iron ore business, stop the bleeding at Bloom Lake, drastically reduce overhead, divest non-core assets and start generating positive returns for shareholders.”

Key issues addressed in Casablanca’s presentation include:

Casablanca’s independent, knowledgeable and experienced Director nominees intend to guide Cliffs for the benefit of all shareholders. Casablanca urges all shareholders to vote their shares FOR Casablanca’s independent nominees on the GOLD proxy card.

Shareholders who have any questions or require assistance in submitting the GOLD proxy card are encouraged to contact Okapi Partners at (212) 297-0720 or (877) 274-8654 (toll-free).
