Cautionary Statement Regarding Forward Looking Information

This press release contains forward-looking statements within the meaning of the U.S. Securities Act of 1933, the U.S. Securities Exchange Act of 1934 (and the equivalent under Canadian securities laws) and the Private Securities Litigation Reform Act, that are intended to be covered by the safe harbor created by such sections. Statements that are not historical fact are forward-looking statements. Forward-looking statements can be identified by, among other things, the use of forward-looking language, such as the words "plan," "believe," "expect," "anticipate," "intend," "estimate," "project," "may," "will," "would," "could," "should," "seeks," or "scheduled to," or other similar words, or the negative of these terms or other variations of these terms or comparable language, or by discussion of strategy or intentions. Such forward-looking statements include, without limitation, statements regarding the timing for completion of the leach pad expansion and Merrill-Crowe processing facility, the expected capacity and sufficiency of the Company's processing facilities upon completion of planned expansion projects, timing of results and indications of exploration drilling currently underway at Hycroft and exploration properties, including the Hasbrouck/Three Hills properties; delays in processing gold and silver, the potential for confirming, upgrading and expanding gold and silver mineralized material; reserve and resource estimates and the timing of the release of updated estimates for the Hasbrouck/Three Hills and Wildcat properties; estimates of gold and silver grades; expectations regarding gold and silver recovery, anticipated sales, costs, project economics, capital expenditures, cash flows and operating costs, the expected sources of capital for the Hycroft expansion and other statements that are not historical facts. Forward-looking statements address activities, events or developments that Allied Nevada expects or anticipates will or may occur in the future, and are based on current expectations and assumptions.

Although Allied Nevada management believes that its expectations are based on reasonable assumptions, it can give no assurance that these expectations will prove correct. Important factors that could cause actual results to differ materially from those in the forward-looking statements include, among others, risks that Allied Nevada's exploration and property advancement efforts will not be successful; delays in the start-up of expansion new processing facilities or operation of new equipment, risks relating to fluctuations in the price of gold and silver; the inherently hazardous nature of mining-related activities; uncertainties concerning reserve and resource estimates; uncertainties relating to obtaining approvals and permits from governmental regulatory authorities; and availability and timing of capital for financing the Company's exploration and development activities, including the uncertainty of being able to raise capital on favorable terms or at all; as well as those factors discussed in Allied Nevada's filings with the U.S. Securities and Exchange Commission (the "SEC") including Allied Nevada's latest Annual Report on Form 10-K and its other SEC filings (and Canadian filings) which may be secured from us, either directly or from our website at www.alliednevada.com or at the SEC website www.sec.gov. The Company does not intend to publicly update any forward-looking statements, whether as a result of new information, future events, or otherwise, except as may be required under applicable securities laws.
