Forward Looking Statements This news release, the Technical Report and June 29 News Release referred to herein contain statements that constitute "forward-looking statements" within the meaning of Section 21E of the United States Securities Exchange Act of 1934 and "forward looking information" within the meaning of applicable Canadian provincial securities legislation (collectively, "forward-looking statements"). Forward-looking statements often, but not always, are identified by the use of words such as "seek", "anticipate", "believe", "plan", "estimate", "expect", "targeting" and "intend" and statements that an event or result "may", "will", "should", "could", or "might" occur or be achieved and other similar expressions. Forward-looking statements in these documents include statements regarding estimates of mineral resources, estimates of gold grades and in-place ounces, estimates of costs, estimates of mine development and construction, estimates of economic potential and returns, projections of future optimization and the timing and nature of future exploration programs.  The description of the extent of mineralized zones is not intended to imply that any economically mineable estimate of reserves exists on the Phoenix Project. Similarly, although geological features of the F2 Gold System are interpreted to show similarities to nearby gold producing mines owned by third parties, this should not be interpreted to mean that the F2 Gold System has, or that it will generate similar reserves or resources.

The forward-looking statements that are contained in these documents are based on various assumptions and estimates by Rubicon and involve a number of risks and uncertainties. As a consequence, actual results might differ materially from results forecast or suggested in these forward-looking statements. Forward-looking statements involve known and unknown risks, uncertainties, assumptions and other factors that may cause the actual results, performance or achievements of Rubicon to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements. Factors that could cause the actual results to differ include; risks relating to fluctuations in the price of gold; the inherently hazardous nature of mining-related activities; uncertainties concerning reserve and resource estimates; results of exploration, availability of capital and financing on acceptable terms, inability to obtain required regulatory approvals, unanticipated difficulties or costs in any rehabilitation which may be necessary, market conditions and general business, economic, competitive, political and social conditions. These statements are based on a number of assumptions, including assumptions regarding general market conditions, timing and receipt of regulatory approvals, the ability of Rubicon and other relevant parties to satisfy regulatory requirements, the availability of financing for proposed transactions and programs on reasonable terms and the ability of third-party service providers to deliver services in a timely manner. Although Rubicon has attempted to identify important factors that could cause actual results to differ materially from those expressed or implied in forward-looking statements, there may be other factors which cause actual results to differ. Forward-looking statements contained herein are made as of the date of this news release and Rubicon disclaims any obligation to update any forward-looking statements, whether as a result of new information, future events or results or otherwise, except as required by applicable securities laws. There can be no assurance that forward-looking statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking statements.
