This information is based on current expectations that are subject to significant risks, assumptions and uncertainties that are difficult to predict. Actual results might differ materially from results suggested in any forward-looking statements. All statements, other than statements of historical fact, included in the presentation, including, without limitation, statements regarding production and operational results, exploration results, and future plans and objectives of Americas Silver, are forward-looking statements. Words such as “expect”, “anticipate”, “estimate”, “may”, “will”, “should”, “intend”, “believe” and other similar expressions are forward-looking statements. Forward-looking statements are not guarantees of future results and conditions but rather reflect our current views with respect to future events and are subject to risks, uncertainties, assumptions and other factors, and actual results and future events could differ materially from those anticipated in such statements.

Americas Silver assumes no obligation to update the forward-looking statements, or to update the reasons why actual results could differ from those reflected in the forward looking-statements unless and until required by securities laws applicable to the Americas Silver . Additional information identifying risks and uncertainties is contained in filings by Americas Silver with the Canadian securities regulators, which filings are available at www.sedar.com. Please note that unless otherwise indicated, all figures are in US dollars.Some of the potential quantities and grades disclosed are conceptual in nature, there has been insufficient exploration to define a mineral resource on all of the mineralization at the Galena Complex and Cosalá Operations and it is uncertain if further exploration will result in certain targets being delineated as a mineral resource.An additional Cautionary Note to Investors – In the event that we use certain terms in this presentation, such as “resource”, “measured resource”, “indicated resource” and “inferred resource”. U.S. investors are cautioned that, while such terms are recognized and required by Canadian Securities Laws, the United States Securities and Exchange Commission does not recognize them. Under U.S. standards, mineralization may not be classified as a “reserve” unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination has been made. U.S. investors should not assume that all or any part of measured or indicated resources will ever be converted into reserves. In addition, “inferred resources” have a greater amount of uncertainty as to their existence and as to whether they can be mined legally or economically. Accordingly, information concerning descriptions of mineralization in this presentation may not be comparable to information made public by companies that are subject to the SEC’s Industry Guide 7.Mr. Daren Dell, Chief Operating Officer and a Qualified Person under Canadian Securities Administrators guidelines has approved the applicable contents of this presentation.  3
