RIO DE JANEIRO, BRAZIL--(Marketwire - March 3, 2008) - MMX Mineração e Metálicos S.A. ("MMX" or the "Company") (BOVESPA: MMXM3) (TSX: XMM), pursuant to article 157 of Law 6404/76, and CVM Instruction No. 358/02, hereby makes the following announcement:

Further to the Public Announcement made on January 15, 2008 ("Original Public Announcement"), we hereby inform that AVX Mineração e Participações Ltda. ("AVX"), a subsidiary of the Company, has concluded the acquisition of Minerminas - Mineradora Minas Gerais Ltda. ("Minerminas").

For the purchase of 100% of Minerminas shares, AVX will pay a total of US$115,625,000.00, payable in 7 semi-annual consecutive installments, which represents a saving of almost US$10 million from the amount announced in the Original Public Announcement. The first installment of US$16,517,857.00 has already been paid and the six remaining installments of equal amount will be paid in the months of July and January of each year, with the last installment due in January 2011.

Through AVX, the Company is merging the operations of AVG and Minerminas in order to obtain synergies and economies of scale. The Company estimates that the integrated operations of AVX should produce 6.1 million tonnes of iron ore in 2008 and 6.6 million tonnes of iron ore in 2009. In this regard, the Company has approved investments of nearly US$40.1 million to improve operations over these two years, which alone will enable AVX to reach production capacity of 8 million tonnes in 2010.

Meanwhile, MMX plans to increase investments for the second stage of expansion of the operating capacity of AVX and, for this purpose, is conducting engineering studies in order to reach production capacity of 10 million tonnes in 2010.
