This news release includes certain statements that may be deemed "forward-looking statements". All statements in this release, other than statements of historical facts, including the plans for the use of the net proceeds of the Offering, and the likelihood of commercial mining are forward-looking statements. Although the Company believes the expectations expressed in such forward-looking statements are based on reasonable assumptions, such statements are not guarantees of future performance and actual results or developments may differ materially from those in the forward-looking statements. Factors that could cause actual results to differ materially from those in forward-looking statements include the inability of the Company to obtain a receipt for the short form prospectus, changes in market conditions, unsuccessful exploration results, changes in the price of gold, unanticipated changes in key management personnel and general economic conditions. Mining exploration and development is an inherently risky business. Accordingly the actual events may differ materially from those projected in the forward-looking statements. For more information on Bonanza and the risks and challenges of its business, investors should review the Company's prospectus dated September 22, 2011 in respect of this Offering as filed on www.sedar.com.
