Cautionary Statement Regarding Forward Looking Information

This press release contains forward-looking statements within the meaning of the U.S. Securities Act of 1933 and the U.S. Securities Exchange Act of 1934 (and the equivalent under Canadian securities laws), that are intended to be covered by the safe harbor created by such sections. Such forward-looking statements include, without limitation, statements regarding the results and indications of exploration drilling currently underway at Hycroft; the potential for confirming, upgrading and expanding gold and silver mineralized material at Hycroft; resource estimates and the timing of the release of updated estimates; estimates of gold and silver grades; 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; 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) including, without limitation, its latest Quarterly Report on Form 10-Q. 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.

The technical contents of this news release have been prepared under the supervision of David C. Flint, a Certified Professional Geologist with American Institute of Professional Geologists (A.I.P.G.), #10360, who is Vice President, Exploration for Allied Nevada Gold Corp. and is a Qualified Person as defined by National Instrument 43-101.

Cautionary Note to U.S. Investors -The United States Securities and Exchange Commission permits U.S. mining companies, in their filings with the SEC, to disclose only those mineral deposits that a company can economically and legally extract or produce. We use certain terms on this website (or press release), such as “measured,” “indicated,” and “inferred” “resources,” which the SEC guidelines strictly prohibit U.S. registered companies from including in their filings with the SEC. U.S. Investors are urged to consider closely the disclosure in our Form 10-K which may be secured from our website or the SEC website at http://www.sec.gov/edgar.shtml.

Non-GAAP Measures

Adjusted cash costs is a non-GAAP measure, calculated on a per ounce of gold sold basis, and includes all normal direct and indirect operating cash costs related directly to the physical activities of producing gold, including mining, processing, third party refining expenses, on-site administrative and support costs, royalties, and mining production taxes, net of by-product revenue earned from silver sales. Adjusted cash cost provides management and investors with a measure to assess the Company’s performance against other precious metals companies and performance of the mining operations over multiple periods. Non-GAAP measures do not have any standardized meaning prescribed by GAAP and, therefore, may not be comparable to similar measures presented by other companies. Accordingly, the above measures are intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. For further information, see our audited financial statements filed with our annual report on Form 10-K.
