PFS, a Preliminary Economic Assessment ("PEA") was completed in
2016, which considered the potential economic merit of
co-developing the high-grade Gryphon and Phoenix deposits as a
single underground mining operation. The PEA returned a base case

the economic considerations applied to them to be categorized as
mineral reserves, and there is no certainty that the preliminary

mineral reserves and do not have demonstrated economic
viability.</font></div>

of Joint Venture expenses in 2017 and 2018 (ordinarily 60%) in

Denison is a uranium exploration and development company with
interests focused in the Athabasca Basin region of northern
Saskatchewan, Canada. In addition to its 63.3% owned Wheeler River
project, which ranks as the largest undeveloped high-grade uranium
project in the infrastructure rich eastern portion of the Athabasca
Basin region, Denison's Athabasca Basin exploration portfolio
consists of numerous projects covering approximately 321,000

Investors Concerning Estimates of Measured, Indicated and Inferred

&#x201C;measured&#x201D;, &#x201C;indicated&#x201D; and

are advised that while such terms are recognized and required by

rules, estimates of inferred mineral resources may not form the
basis of feasibility or other economic studies. United States
investors are cautioned not to assume that all or any part of
measured or indicated mineral resources will ever be converted into
mineral reserves. United States investors are also cautioned not to
assume that all or any part of an inferred mineral resource exists,
