Cautionary Note Regarding Forward-looking Information 
Statements contained in this presentation that are not current or historical factual statements may constitute “forward-looking information” within the meaning of applicable securities laws including statements with respect to the properties, a concurrent financing, our plans for exploration and development of our properties and our financial condition, operations and prospects. The forward-looking information reflects current expectations regarding future results, performance or achievements and speaks only as of the date of this presentation. When used in this presentation, forward-looking information can be identified by such words as “may”, “will”, “expect”, “believe”, “plan”, “project”, “anticipate”, “intend”, “estimate” and other similar terminology. Such forward-looking information involves known and unknown risks, uncertainties and other factors that may cause the actual results, performance or achievements of the Company to be materially different from any future results, performance or achievements expressed in or implied by such information. Such risks, uncertainties and other factors include, but are not limited in any manner to those risks set forth in this presentation under the heading “Risk Factors”, including, the risk that no mineralization will be identified on the Radio and Rook I properties; the Company’s dependence on third party financing; the Company’s limited operating history; risks inherent in exploration activities; environmental and safety risks including increased regulatory burdens; unexpected geological or hydrological conditions; a possible deterioration in political support for nuclear energy; changes in government regulations and policies, including trade laws and policies; demand for nuclear power; failure to obtain necessary permits and approvals from government authorities; weather and other natural phenomena; and other exploration, development, operating, financial market and regulatory risks. The foregoing list of factors is not exhaustive. 
The forward-looking information contained in this presentation requires management to make certain assumptions including with respect to the financing and its ability to successfully develop its properties. Although management of the Company believes that the assumptions underlying, and the expectations reflected in, the forward-looking information are reasonable, significant risks and uncertainties are involved in such information. Management can give no assurances that its assumptions, estimates and expectations will prove to have been correct. Forward-looking information should not be read as guarantees of future performance or results, and will not necessarily be accurate indications of whether or not or the times at or by which such performance or results will be achieved. Many factors that are beyond the Company’s control could cause actual results to differ materially from the results discussed in the forward-looking statements.
