2. DISCLAIMER
This presentation relating to MMX Mineração e Metálicos S.A. (“MMX”) includes “forward-looking statements”, as that term
is defined in the Private Securities Litigation Reform Act of 1995, in Section 27A of the Securities Act of 1933 and Section
21E of the U.S. Securities Exchange Act of 1934. All statements other than statements of historical facts are statements
that could be deemed forward-looking statements and are often characterized by the use of words such as “projects”,
“expects”, “anticipates”, “intends”, “plans”, “believes”, “estimates”, “may”, “will”, or “intends”, or by discussions or
comments about our objectives, strategy, plans or intentions and results of operations. Forward-looking statements include
projections regarding our operating capacity, operating expenditures, capital expenditures and start-up dates.
By their nature, these forward-looking statements involve numerous assumptions, uncertainties and opportunities, both
general and specific. The risk exists that these statements may not be fulfilled or, even if they are fulfilled, the results or
developments described in such statements may not be indicative of results or developments in future periods. We caution
participants of this presentation not to place undue reliance on these forward-looking statements as a number of factors
could cause future results to differ materially from these statements.
Forward-looking statements may be influenced in particular by factors such as the ability to obtain all required regulatory
approvals on a timely basis or at all, exploration for mineral resources and reserves, difficulty in converting geological
resources into mineral reserves, and changes in economic, political and regulatory conditions. We caution that the
foregoing list is not exhaustive. When relying on forward-looking statements to make decisions, investors should carefully
consider these factors as well as other uncertainties and events.
MMX does not undertake to update our forward-looking statements unless required by law. This presentation is neither an
offer to sell (which can only be made pursuant to definitive offering documents) nor a solicitation of an offer to buy any
securities in the United States, or any other jurisdiction. The securities referred to herein have not been registered in any
