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”,

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

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.

Project Overview Project Overview Focus High tonnage, high grade, technically superior assets in shallow sections of the Athabasca Basin

4

South West Athabasca Basin NexGen owns the most dominant land package in this section of the Basin

Portfolio Characteristics

- Straddles the Basin boundary and shallow sections inside the Basin

- Hosts the land based Arrow discovery at Rook I

- Hosts all known uranium

bearing conductor corridors

5

Arrow Discovery Rook I Project location & Conductor Corridors

Arrow Discovery - Discovered February

2014, - Land based located

inside the Basin boundary

- 30 from 32 holes drilled to date intersected multiple high grade uranium mineralisation

- AR-14-30 ranked as one of the best holes in the Athabasca Basin

Rook I hosts all the known uranium bearing conductor corridors in the region

Arrow Discovery / Eagle Point Deposit Analogy

65 million lbs produced, 20 million lbs reserve, within >200 million lb district

- Eagle Point Uranium deposits are located on the eastern edge of the Athabasca Basin, and are part of the Rabbit Lake Uranium district, which also includes the Rabbit Lake and Collins Bay deposits. - The Rabbit Lake Uranium District has produced more than 190 million pounds of uranium concentrates since production began in 1975 (www.cameco.com/business/uranium-operations/canada/rabbit-lake). - In 1987, a historical (non 43-101 compliant) “total ore reserve” for the Eagle Point deposits comprised approximately 140 Million pounds (64,000 tonnes) at an average grade of about 2.0% U3O8 (Eldorado Resources Limited. 1987. The Eagle Point Uranium Deposits. Saskatchewan Geological Society. Economic Minerals of Saskatchewan. Pg. 78-98). - Production commenced in 1994 and is in production today.

The Arrow zone is located just inside the present day Athabasca Basin where no drill testing has occurred within 4 km along strike to the northeast within the Athabasca Basin, and within 3 km along strike to the southwest outside of the Athabasca Basin.

Eastern Athabasca Basin Portfolio

High quality portfolio

- Radio located directly adjacent to and long strike of Roughrider, Rio Tinto acquired for $654M in February 2012

Thorburn Lake (9 of 15 drill holes have intersected uranium mineralization)

Madison and 2Z Lake projects contain shallow (<100m thick) sandstone-hosted uranium mineralisation, and is along strike from U-mineralized conductors. The mineralized structures and conductors within 2Z have not been adequately explored, and represent good potential for discovery of new basement-hosted uranium deposits.
