The information contained herein contains "forward -looking statements" within the meaning of applicable

United States securities laws and regulations and "forward -looking information" within the meaning of

applicable Canadian securities legisla tion. "Forward -looking information" includes, but is not limited to,

statements with respect to mineral reserve and mineral resource estimates, the 2021 Arrow Deposit, Rook I

Project and estimates of uranium production, grade and long-term average uranium prices, anticipated effects

of completed drill results on the Rook I Project, planned work programs, completion of further site

investigations and engineering work to support basic engineering of the project and expected outcomes.

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 va riations of such words and phrases or

state that certain actions, events or results "may", "could", "would", "might" or "will be taken", "occur" or "be

achieved" or the negative connotation thereof. Statements relating to "mineral resources" are deemed to be

forward-looking information, as they involve the implied assessment that, based on certain estimates and

assumptions, the mineral resources described can be profitably produced in the future.

Forward-looking information and statements are based on the then current expectations, beliefs, assumptions,

estimates and forecasts about NexGen's business and the industry and markets in which it operates. Forward-

looking information and statements are made based upon numerous assumptions, including among others,

that the mineral reserve and resources estimates and the key assumptions and parameters on which such

estimates are based are as set out in this news release and the technical report for the property , the results

of planned exploration activities are as a nticipated, the price and market supply of uranium, the cost of

planned exploration activities, that financing will be available if and when needed and on reasonable terms,

that third party contractors, equipment, supplies and governmental and other approvals required to conduct

NexGen's planned exploration activities will be available on reasonable terms and in a timely manner and that

general business and economic conditions will not change in a material adverse manner. Although the

assumptions made by th e 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 in the future.

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

other factors, which may cause actual results, performances and achievements of NexGen to differ materially

from any projections of results, performances and achievements of NexGen expressed or implied by such

forward-looking information or statements, including, among others, the existence of negative operating cash

flow and dependence on third party financing, uncertainty of the availability of additional financing, the risk

that pending assay results will not confirm previously announced preliminary results, conclusions of economic

valuations, the risk that actual results of exploration activities will be different than anticipated, the cost of

labour, equipment or materials will increase more than expected, that the future price of uranium will decline

or otherwise not rise to an economic level, the appeal of alternate sources of energy to uranium -produced

energy, that the Canadian dollar will strengthen against the U.S. dollar, t hat mineral resources and reserves

are not as estimated, that actual costs or actual results of reclamation activities are greater than expected,

that changes in project parameters and plans continue to be refined and may result in increased costs, of

unexpected variations in mineral resources and reserves, grade or recovery rates or other risks generally

associated with mining, unanticipated delays in obtaining governmental, regulatory or First Nations approvals,

risks related to First Nations title and co nsultation, reliance upon key management and other personnel,

deficiencies in the Company's title to its properties, uninsurable risks, failure to manage conflicts of interest,

failure to obtain or maintain required permits and licences, risks related to changes in laws, regulations, policy

and public perception, as well as those factors or other risks as more fully described in NexGen's Annual

of Canada except Quebec and in NexGen's 40 -F filed with the United States Securities and Exchange

Commission, which are available on SEDAR at www.sedar.com and Edgar at www.sec.gov .

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 statements or implied by forward-looking

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

or intended. Readers are cautioned not to place undue reliance on forward-looking information or statements

due to the inherent uncertainty thereof.
