Re.: OFFICIAL LETTER GAE 4.466 -13("Official Letter")

Gentlemen,
We refer to the Official Letter received on December 12th , 2013, requesting that MMX Mineração e Metálicos S.A., holding address at Praia do Flamengo 66, 10th floor, corporate tax identification (CNPJ/MF) n.º 02.762.115/0001-49 ("MMX" or "Company") provide explanations on the content of the news reported in 'Folha de São Paulo, under the heading "Businessman tries to merge MMX to other mining companies".
Although the Company does not comment upon market rumors, nor articles in the press, in order to comply with your request, MMX reaffirms that, pursuant to the material fact disclosed to the market on November 27th, 2013 ("Material Fact"), the Board of Directors of MMX approved the Revision of the Business Plan of the Company, submitted to the market in conference call held on December 2nd, 2013 . During the conference call, MMX informed that, in accordance to the Revision of its Business Plan, the Company seeks for partners in order to implement the project of expansion of Serra Azul's Unit and that, for this purpose, had hired 2 (two) Financial Advisor. In this context, MMX has ongoing discussions with various market players. However, at this point in time, no biding document has been signed nor has anything been defined that would enable the Company to affirm that it will take one path or another, which is why the Material Fact provided no details of potentially interested parties, such as reported in the said new item on December 12th, 2013.
MMX will keep its shareholders and the market at large informed as soon as there is any fact or decision liable to be disclosed in a complete, sufficient and suitable manner.
