EXHIBIT 99.2

Mr. Lourenco Goncalves

Chairman, President and Chief Executive Officer

Cliffs Natural Resources Inc.

200 Public Square

Cleveland, Ohio 44114-2544

September 12, 2014

Dear Mr. Goncalves:

I hereby tender my resignation as a director of Cliffs Natural Resources Inc., effective immediately.

I respect the recent decision by the Cliffs’ shareholders to elect you and a majority of new directors to the company’s board. After careful consideration, I have concluded that under the current circumstances, my ability to influence Cliffs’ future direction and thereby serve the interests of all of its shareholders has become limited.

I have great admiration for Cliffs and have thoroughly enjoyed working with its dedicated employees. I wish Cliffs success in the future.

Very truly yours,

Mark Gaumond
