Forward-Looking Information

The information contained herein contains “forward- looking statements” within the meaning of the

United States Private Securities Litigation Reform Act of 1995 and “forward -looking information” within

the meaning of applicable Canadian securities legislation. “Forward-looking information” includes, but is

not limited to, statements with respect to the activities, events or developments that the Company

expects or anticipates will or may occur in the future, including, without limitation, planned exploration

activities statements regarding completion of the Additional Offerings, the anticipated Closing Date and

the use of

proceeds from the Additional Offerings. Generally, but not always, forward -looking information and

statements can be identified by the use of words such as “plans”, “expects”, “is expected”, “budget”,

“scheduled”, “estimates”, “forecasts”, “intends”, “anticipates”, or “believes” or the negative connotation

thereof or variations of such words and phrases or state that certain actions, events or r esults “may”,

“could”, “would”, “might” or “will be taken”, “occur” or “be achieved” or the negative connotation

thereof.

Such forward-looking information and statements are based on numerous assumptions, including among

others, that the results of planned exploration activities are as anticipated, the price of uranium, the

anticipated cost of planned exploration activities, that general business and economic conditions will not

change in a material adverse manner, that financing will be available if and w hen needed and on

reasonable terms, that third party contractors, equipment and supplies and governmental and other

approvals required to conduct the Company’s planned exploration activities will be available on

reasonable terms and in a timely manner. Although the assumptions made by the Company in providing

forward-looking information or making forward -looking statements are considered reasonable by

management at the time, there can be no assurance that such assumptions will prove to be accurate.

Forward-looking information and statements also involve known and unknown risks and uncertainties and

other factors, which may cause actual events or results in future periods to differ materially from any

39851|7635288_6

projections of future events or results expressed or impli ed by such forward -looking information or

statements, including, among others: negative operating cash flow and dependence on third party

financing, uncertainty of additional financing, no known mineral reserves or resources, the limited

operating history of the Company, the influence of a large shareholder, alternative sources of energy and

uranium prices, aboriginal title and consultation issues, reliance on key management and other personnel,

actual results of exploration activities being different than anticipated, changes in exploration programs

based upon results, availability of third party contractors, availability of equipment and supplies, failure

of equipment to operate as anticipated; accidents, effects of weather and other natural phenomena and

other risks associated with the mineral exploration industry, environmental risks, changes in laws and

regulations, community relations and delays in obtaining governmental or other approvals.

Although the Company has attempted to identify important factors that could cause actual results to differ

materially from those contained in the forward -looking information or implied by forward -looking

information, there may be other factors that cause results not to be as anticipated, estimated or intended.

There can be no assurance that forward-looking information and statements will prove to be accurate, as

actual results and future events could differ materially from those anticipated, estimated or intended.

Accordingly, readers should not place undue reliance on forward-looking statements or information. The

Company undertakes no obligation to update or reissue forward -looking information as a result of new

information or events except as required by applicable securities laws.
