Mineral Resource

While the terms "mineral resource" and "inferred mineral resource" are recognized and required by Canadian regulations, they are not defined terms under standards in the United States. As such, information contained in this report concerning descriptions of mineralization and resources under Canadian standards may not be comparable to similar information made public by U.S. companies subject to the reporting and disclosure requirements of the United States Securities and Exchange Commission ("SEC"). "Inferred mineral resources" have a great amount of uncertainty as to their existence and a great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an "inferred mineral resource" will ever be upgraded to a higher category. Investors are cautioned not to assume that any part or all of mineral deposits in this category will ever be converted into reserves.

This press release contains forward-looking information within the meaning of Canadian securities laws and forward-looking statements within the meaning of U.S. securities laws ("forward-looking statements"). Forward looking statements are typically identified by words such as: believe, expect, anticipate, intend, estimate, plans, postulate and similar expressions, or are those, which, by their nature, refer to future events. All statements that are not statements of historical fact are forward-looking statements. Forward-looking statements in this press release include, without limitation, statements regarding mineral resource estimates. Although the Company believes the forward-looking statements in this press release are reasonable, it can give no assurance that the expectations and assumptions in such statements will prove to be correct. The Company cautions investors that any forward-looking statements by the Company are not guarantees of future results or performance, and that actual results may differ materially from those in forward looking statements as a result of various factors, including, but not limited to: variations in market conditions; the nature, quality and quantity of any mineral deposits that may be locate; the Company's ability to obtain any necessary permits, consents or authorizations required for its activities; the Company's ability to successfully complete hedging establishment and off-take negotiations; the Company's ability to produce minerals from its properties successfully or profitably, to continue its projected growth, or to be fully able to implement its business strategies and other risk factors described in the Company's Form 40-F annual report, annual information form and other filings with the SEC and Canadian securities regulators, which may be viewed at www.sec.gov and www.sedar.com, respectively.
