<font style="font-family: Arial; font-size: 13px">On March 20,
2020, Denison announced a temporary suspension of activities
related to the EA for Wheeler River. An important element of the EA
process is the completion of extensive in-person engagement and
consultation activities with various interested parties and
community groups. The decision to suspend the EA process and other
discretionary activities is motivated by the significant social and
economic disruption that has emerged as a result of the COVID-19
pandemic and the Company&#x2019;s commitment to ensure employee
safety, support public health efforts to limit transmission of
COVID-19, and exercise prudent financial discipline.</font></div>

<font style="font-family: Arial; font-size: 13px">The EA is a
planning and decision-making tool, which involves predicting
potential environmental effects throughout the project lifecycle
(construction, operation, decommissioning and post-decommissioning)
at the site, and within the local and regional assessment areas.
During the first quarter of 2019, Denison submitted a Project
Description to the Canadian Nuclear Safety Commission
(&#x201C;<font style="font-weight: bold">CNSC</font>&#x201D;) and a
Technical Proposal to the Saskatchewan Ministry of Environment
(&#x201D;<font style="font-weight: bold">SK MOE</font>&#x201D;) to
support the advancement of an In-Situ Recovery (&#x201C;<font style="font-weight: bold">ISR</font>&#x201D;) uranium mine at Wheeler
River. This work followed the release of the Pre-Feasibility Study
(&#x201C;<font style="font-weight: bold">PFS</font>&#x201D;)
completed for Wheeler River in late 2018, considering the potential
economic merit of developing the Phoenix deposit as an ISR
operation and the Gryphon deposit as a conventional underground
mining operation.</font></div>

<font style="font-family: Arial; font-size: 13px">The Project
Description and Technical Proposal were accepted in the second
quarter of 2019, initiating the EA process for the Project in
accordance with the requirements of both the <font style="font-style: italic">Canadian Environmental Assessment Act</font>,
2012 (&#x201D;<font style="font-weight: bold">CEAA
2012</font>&#x201D;) and the <font style="font-style: italic">Saskatchewan Environmental Assessment
Act</font>. In late December 2019, Denison received a Record of
Decision from the CNSC on the scope of the factors to be taken into
account for the Wheeler EA, which indicate that the EA will follow
the CNSC's generic guidelines. Significant progress has been made
in collecting environmental baseline data in previous years, and
the current focus of EA related activities is split between
engagement with interested parties and the completion of various
environmental assessments and studies related to the predicted
environmental effects of the Project.</font></div>

<font style="font-family: Arial; font-size: 13px">The Company
identified the EA process as a key element of the Project's
critical path. Accordingly, Denison initiated various studies and
assessments to support the preparation of the Project Environmental
Impact Statement (&#x201C;<font style="font-weight: bold">EIS</font>&#x201D;), following the decision to
advance the Wheeler River project in late 2018 as announced on
December 18, 2018. The decision to temporarily suspend the EA
process is expected to impact the project development schedule
outlined in the PFS for Wheeler River. Given the uncertainty
associated with the duration of the suspension, the Company is not
currently able to estimate the impact to schedule. Further
information, including a revised development schedule, will be
provided as appropriate.</font></div>

announced its plans for 2020 in its annual MD&amp;A for the year
ended December 31, 2019 (the &#x201C;<font style="font-weight: bold">2020 Outlook</font>&#x201D;). Those plans
identified two discretionary work programs related to the
advancement of Wheeler River: (1) the continuation of the EA and
submission of a draft EIS to the Federal and Provincial regulators
(approximately $7.0 million), and (2) the completion of further ISR
field testing to support wellfield designs for a future Feasibility
Study (approximately $6.6 million). Given the decision to suspend
the EA, and the current economic disruption associated with
COVID-19, these work programs are not currently expected to advance
in 2020. Based on the 2020 Outlook, the Company intends to maintain
its environmental and technical teams in 2020 and to selectively
advance certain scopes of work, outside of the discretionary work
programs, to position the Company to quickly resume project
development activities in the future and minimize the impact to the
project schedule.</font></div>

this report contains forward-looking information pertaining to the
following: the EA process, including its intended scope, objectives

thereto (including potential for delays as a result of the
temporary suspension of the EA and other discretionary programs and

<font style="font-family: Arial; font-size: 11px">Forward looking
statements are based on the opinions and estimates of management as
of the date such statements are made, and they are subject to known
and unknown risks, uncertainties and other factors that may cause
the actual results, level of activity, performance or achievements
of Denison to be materially different from those expressed or
implied by such forward-looking statements. For example, if market
conditions remain volatile and/or COVID-19 mitigation measures
result in more social and economic disruptions, Denison may need to
further re-assess its discretionary and non-discretionary
expenditures and programs for 2020 and beyond, which could have
significant impacts on Denison and/or the development of the
Project. Denison believes that the expectations reflected in this
forward-looking information are reasonable but no assurance can be
given that these expectations will prove to be accurate and results
may differ materially from those anticipated in this
forward-looking information. For a discussion in respect of risks
and other factors that could influence forward-looking events,
please refer to the factors discussed in Denison&#x2019;s Annual
Information Form dated March 13, 2020 under the heading &#x2018;Risk
Factors&#x2019;. These factors are not, and should not be construed
as being exhaustive.</font></div>
