RIO DE JANEIRO, BRAZIL--(Marketwire - August 3, 2009) - Pursuant to the article 157, paragraph 4 of Law No. 6.404 of December 15th, 1976, as amended, and in accordance with Brazilian Securities Exchange Comission ("CVM") Rule No. 358 of January 3rd, 2002, MMX Mineração e Metálicos S.A. (BOVESPA: MMXM3) ("MMX" or the "Company") hereby informs its shareholders and the market that its Board of Directors approved a change in the senior management of the Company at a meeting held as of today.

Mr. Roger Allan Downey was appointed as the new Chief Executive Officer of MMX. Until now, Mr. Eike Batista accumulated the functions of Chief Executive Officer and Chairman of the Board of the Company, and will remain in the last position. Mr. Chequer Hanna Bou-Habib, who accumulated the roles of Commercial and Investor Relations Officer, will dedicate exclusively himself to the leadership of the commercial area and Roger Downey will assume the position of Investor Relations Officer.

Roger Downey joins MMX from Credit Suisse, where he was responsible for coverage of the mining and steel companies in Latin America since 2005. Before that, Roger Downey worked for 14 years in the mining industry in sales, marketing, business development and strategy areas of important iron ore world producers, such as Vale and Rio Tinto.

Mr. Joaquim Martino Ferreira, until now Executive Officer of MMX, leaves the executive functions to become Special Adviser of EBX Group for mining activities. Thus, Mr. Joaquim Martino will continue contributing with his extensive experience in deployment and operation of mining projects. Additionally, Mr. Joaquim Martino will be nominated to become a member of MMX's Board of Directors, as Vice Chairman, what will be voted in an Extraordinary General Shareholder's Meeting to be held soon, as approved at the Meeting of Board of Directors today.

For the controlling shareholder of MMX, Mr. Eike Batista, "A promising future, of significant wealth creation, dawns for MMX. We have already created extraordinary value for the Company since 2006, which has been shared with all shareholders. We put 2 iron ore systems into operation in record time, with high grade iron ore, low cost and integrated logistics. We have also designed a magnificent project, world-class, now being developed by Anglo American Group. Joaquim Martino's experience leading a competent technical team was crucial for this to become reality. We will continue to rely on his expertise in EBX Group and Roger Downey will be essential to consolidate MMX's current business plan and to identify new paths for growth."
