MMX Minera��o e Met�licos S.A. (�MMX� or the �Company�) (PINK SHEETS:MMXMY) (BOVESPA:MMXM3) (TSX:XMM), pursuant to article 157 of Law 6404/76, and CVM Instruction No. 358/02, hereby makes the following announcement: MMX has concluded the purchase of 100% of AVG Minera��o S.A. (�AVG�) shares, for US$224 million, as expected, in line with the MMX and AVG shareholders agreement announced on July 5, 2007. The purchase price may accrete by a variable portion, capped at US$50 million, subject to the attainment of the necessary environmental permits for certain mining rights, which may increase the mining reserves base of the acquired company. The first installment of the purchase price, in the amount of US$44 million (R$79.2 million), has been paid and the remaining four installments of US$45 million each will be paid on August 30th of the next four years. MMX has found that AVG�s production capacity may be increased from the current 2.3 million tons to 5.8 million tons per year, given results of technical studies and due diligence performed on AVG. MMX believes that AVG may increase its overall efficiency and productivity, due to: 1) improvement in AVG�s operational process; 2) replacement of equipments near the useful life end, and; 3) implementation of maintenance procedures and routines. MMX�s management has approved, on this date, an investment plan for AVG in 2008 and 2009, with a total estimated value of US$32 million, of which US$12 million for current investments and US$20 million for expansion investment. In the future, MMX plans to expand its investment in AVG to initiate a second stage in AVG�s production capacity, which should exceed the planned 5.8 million tons per year, and, for this purpose, is continuing the engineering studies that will sustain the new expansion.

FORWARD-LOOKING STATEMENTS: This material fact contains certain �forward-looking statements� and �forward-looking information� under applicable Canadian securities laws concerning the proposed acquisition operation and the business plan, the operations and financial performance and condition of MMX, and estimated production and mine life of the acquired mineral project. Except for statements of historical fact relating to MMX, certain information contained herein constitutes forward-looking statements. Forward-looking statements are frequently characterized by words such as �plan,� �expect,� �project,� �intend,� �believe,� �anticipate�, �estimate� and other similar words, or statements that certain events or conditions �may� or �will� occur. Forward-looking statements are based on the opinions and estimates of management at the date the statements are made, and are made taking into consideration a number of assumptions and, therefore are subject to a variety of risks and uncertainties and other factors that could cause actual events or results to differ materially from those projected in the forward-looking statements. Assumptions upon which such forward-looking statements are based include MMX being successful in acquiring 100% of the issued and outstanding shares of AVG, any necessary third party, regulatory or governmental approvals for the acquisition operation being obtained, all required environmental and other licenses being obtained and all other conditions to the completion of the acquisition transaction will be satisfied or waived. Many of these assumptions are based on factors and events that are not within the control of MMX and there is no assurance they will prove to be correct. Factors that could cause actual results to vary materially from results anticipated by such forward-looking statements include changes in market conditions, variations in ore grade or recovery rates, risks relating to international operations, fluctuating metal prices and currency exchange rates, changes in project parameters, the possibility of unanticipated costs and expenses, failure of plant, equipment or processes to operate as anticipated, the failure to obtain necessary licenses or permitting, the acquired mineral project not being integrated successfully or such integration proving more difficult, time consuming or costly than expected, and other risks of the mining industry. Although MMX has attempted to identify the important factors that could cause actual actions, events or results to differ materially from those described in forward-looking statements, there may be other factors that cause actions, events or results not to be anticipated, estimated or intended. There can be no assurance that forward-looking statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. MMX undertakes no obligation to update forward-looking statements if circumstances or management�s estimates or opinions should change, except as required by applicable securities laws. The reader is cautioned not to place undue reliance on forward-looking statements.
