Forward-looking information in this press release includes, but is not limited to, statements about our plans regarding future acquisitions and property development, our expectations regarding the uranium market, global growth and the use of nuclear power, our drill results, commodity prices and core intersection lengths, in that they constitute estimates, based on certain assumptions of mineralization that may be encountered if a deposit were to be mined.

By its nature, forward-looking information involves known and unknown risks, uncertainties and other factors which may cause our actual results, performance or achievements, or industry results, to differ materially from those expressed or implied by such forward-looking information. Some of the risks and other factors that could cause actual results to differ materially from those expressed in the forward-looking information contained in this release include, but are not limited to: risks and uncertainties relating to the interpretation of drill results, the geology, grade and continuity of mineral deposits and conclusions of economic evaluations; results of initial feasibility, pre-feasibility and feasibility studies, and the possibility that future exploration, development or mining results will not be consistent with the Company's expectations; risks relating to possible variations in reserves, grade, planned mining dilution and ore loss, or recovery rates and changes in project parameters as plans continue to be refined; mining and development risks, including risks related to accidents, equipment breakdowns, labour disputes (including work stoppages and strikes) or other unanticipated difficulties with or interruptions in exploration and development; the potential for delays in exploration or development activities or the completion of feasibility studies; risks related to the inherent uncertainty of production and cost estimates and the potential for unexpected costs and expenses; risks related to commodity price and foreign exchange rate fluctuations; the uncertainty of profitability based upon the cyclical nature of the industry in which the Company operates; risks related to failure to obtain adequate financing on a timely basis and on acceptable terms or delays in obtaining governmental approvals or in the completion of development or construction activities; risks related to environmental regulation and liability; political and regulatory risks associated with mining and exploration; and other risks and uncertainties related to the Company's prospects, properties and business strategy.

NOTE REGARDING DISCLOSURE FOR MINERAL PROJECTS

This press release contains disclosure regarding our mineral resources. Mineral resources are not mineral reserves and do not have demonstrated economic viability. Mineral resources may never be converted into reserves. Furthermore, inferred resources are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves. Further exploration will be required to upgrade the inferred resources to a higher resource category.
