CNPJ/MF: 02.762.115/0001-49
NIRE: 33.3.0026111-7 (Publicly Held Company)

MATERIAL FACT MMX Mineração e Metálicos S.A. ("Company" or "MMX"), the only Brazilian iron ore mining company with integrated logistics listed on the BM&FBovespa New Market, in compliance with the Article 157, paragraph 4, of the Law No 6,404/76 ("Brazilian Corporations Law") and Comissão de Valores Mobiliários (Brazilian Securities and Exchange Commission)

("CVM") Instruction No. 358/02, hereby informs to its shareholders and to the market in general
that its subsidiary MMX Sudeste Mineração S.A., industrial plant for the production of iron ore in the Serra Azul region, located in the cities of Igarapé, Brumadinho and São Joaquim de Bicas, in the State of Minas Gerais ("Serra Azul Unit"), will grant to its employees a collective vacation period of thirty (30) days, beginning on the first week of September. Back office and maintenance and conservation employees of the Serra Azul Unit will continue their regular activities during such period.
The necessity of the collective vacation and temporary stop of the production activities at the Serra Azul Unit is a consequence of the significant and prolonged decline of the iron ore price in the international market, as well as the operating restrictions imposed by the environmental authorities of the State of Minas Gerais until determination of the cavities' protection areas existing in certain mining sectors. MMX is currently engaged in discussions with the relevant authorities regarding such operating restrictions in order to find a solution that would allow it to resume its activities in the short-term. During such period, the Company will focus on the reduction of costs, optimization of resources for mining activities and modernization of its current facilities, ensuring volume and quality efficiency improvements for the resumption of its activities and mitigating the impact of the prices decline.
The Company also informs that it will review its business plan in order to prioritize the initiatives for cash generation, in the best interest of the Company and its shareholders, taking into account the current market environment, the Company's short- and mid-term cash needs, and the
economic and financial perspective of the business model of the Company.
