PRESS RELEASE
DENISON REPORTS WHEELER RIVER SUMMER ASSAYS
AHEAD OF RESOURCE ESTIMATE
Toronto, ON – November 27, 2017 Denison Mines Corp. (“Denison” or the “Company”) (T SX: DML)
(NYSE MKT: DNN) (NYSE American: DNN) is pleased to report assay results from the 64 drill holes
(totalling 29,823 metres) completed as part of the summer 2017 exploration program on the Company’s
60% owned Wheeler River project. The primary objec tives of the summer exploration program were to
increase the confidence of the Gryphon resource to an indicated level, and to expand the overall size of the
estimated resources, ahead of an updated resource e stimate scheduled for later in the year and the Pre -
Feasibility Study ("PFS") scheduled for 2018.
Highlight assay statistics from the summer 2017 drilling program include:
• On average, assay grades (“U 3O8”) were 39% higher than the previously reported pre liminary
radiometric probe grades (“eU 3O8”) and grade x thickness (GT) values were 34% higher;
• Of the 64 drill holes completed during the summer program, 58 of the drill holes (91%) intersected
significant uranium mineralization (> 0.1% U 3O8 over 1.0 metre);
• Of the 44 drill holes targeting mineralization out side of the current resources estimated for the
Gryphon deposit, 38 of these drill holes (86%) inte rsected significant uranium mineralization (>
0.1% U3O8 over 1.0 metre) with 28 drill holes (64%) intersecting high-grades (> 1.0% U3O8 over 1.0
metre).
• The 20 drill holes, completed to increase the conf idence of the current Gryphon resource to an
indicated level, were all significantly mineralized (> 0.1% U3O8 over 1.0 metre), with 16 of these drill
holes (80%) intersecting high-grades (> 1.0% U 3O8 over 1.0 metre).
Dale Verran, Denison’s Vice President Exploration, commented, “The assay results confirm what has been
a phenomenal season of drilling on the Wheeler River property. Results from the final round of definition
drilling of the current inferred Gryphon resource did not disappoint and we have been very satisfied with
the continuity and grade of the mineralization in comparison with the inferred block model. The summer
program was highlighted by the expansion of high-gr ade within the D series lenses and the discovery
and expansion of the E series lenses, both of which are located outside of the current resources
estimated for Gryphon. We are looking forward to the independent resource estimate in accordance with
NI43-101 in the coming weeks, which will include the results from an additional 141 drill holes completed
at Gryphon since the maiden resource estimate in late 2015.”
Highlight results confirmed by assays from the summer drill program include:
• Continued expansion of high-grade within the D seri es lenses: During the summer program, a
significant lens of high-grade mineralization has been expanded and delineated in all directions amongst
the D series lenses by infill and step-out drilling on an approximate 25 x 25 metres spacing. The high -
grade lens is interpreted from 29 drill holes (12 drill holes from previous drill programs) and is estimated
to measure up to 150 metres along strike, approxima tely 240 metres along dip, with interpreted true
thicknesses between approximately 2 and 20 metres. All D series lens mineralization occurs outside of
the current resources estimated for the Gryphon dep osit. Highlight summer 2017 assay intersections
include:
o 3.5% U 3O8 over 8.0 metres (WR-694)
o 6.3% U 3O8 over 3.0 metres (WR-621D2)
o 4.7% U 3O8 over 3.5 metres (WR-690D2)
o 1.8% U 3O8 over 5.5 meters (WR-657D1)

o 6.4% U 3O8 over 1.5 metres (WR-621D1)
o 4.3% U 3O8 over 2.0 metres (WR-657D3)
o 8.5% U 3O8 over 1.0 metres (WR-690D1)
o 5.5% U 3O8 over 1.5 metres (WR-638D4)
o 2.8% U 3O8 over 2.5 meters (WR-691)
• Extension of the E series lenses: Mineralization was extended within the E series le nses both at the
unconformity and in the underlying upper basement d uring the summer drill program. The high-grade
unconformity and basement lenses are interpreted from 19 drill holes and are estimated to measure up
to 80 metres and 350 metres along strike, respectiv ely. The E series lenses also occur outside of the
current resources estimated for the Gryphon deposit . Highlight summer 2017 assay intersections
include:
o 12.9% U 3O8 over 3.0 metres (WR-689D3) ( Unconformity )
o 2.8% U 3O8 over 7.0 metres (WR-670D2) ( Unconformity )
o 8.8% U 3O8 over 1.5 metres (WR-646D2) ( Upper basement )
o 3.2% U 3O8 over 3.0 metres (WR-636D3) (Upper basement)
o 1.4% U 3O8 over 7.5 metres (WR-646D4) ( Upper basement )
• Continued expansion of the A and B series lenses: Drill holes located approximately 25 metres
down-dip and up-dip of the boundaries of the A and B series lenses, as defined by the current resources
estimated for the Gryphon deposit, returned signifi cant results with the potential to add additional
indicated resources to the Gryphon deposit. Highlight summer 2017 assay intersections include:
o 4.1% U 3O8 over 6.5 metres (WR-582D3) (Gryphon Down Plunge, Up-Dip Area)
o 3.5% U 3O8 over 4.5 metres (WR-638D4) (Gryphon Down Plunge, Up-Dip Area)
o 6.6% U 3O8 over 3.0 metres (WR-681D3) (Gryphon Up Plunge, Down-Dip Area)
o 1.7% U 3O8 over 1.5 metres (WR-681AD2) (Gryphon Up Plunge, Down-Dip Area)
o 1.6% U 3O8 over 3.5 metres (WR-682D1) (Gryphon Up Plunge, Down-Dip Area)
o 5.0% U 3O8 over 5.5 metres (WR-624D3) (Gryphon Up Plunge, Up-Dip Area)
o 2.3% U 3O8 over 2.0 metres (WR-673D1) (Gryphon Up Plunge, Up-Dip Area)
• Completion of the definition drilling program: Definition drilling designed to upgrade the current
inferred resources estimated for the Gryphon deposi t (A, B and C series lenses), to an indicated level
of confidence, has been completed. A total program of 42 drill holes successfully reached their
respective targets as part of definition drilling a ctivities carried out through 2016 and 2017. The as say
results show good consistency with the inferred gra de model. Highlight summer 2017 assay
intersections include:
o 2.3 % U 3O8 over 18.5 metres (WR-604D1)
o 4.0% U 3O8 over 6.0 metres and 5.8% U3O8 over 6.0 metres (WR-692)
o 4.8% U 3O8 over 6.0 meters (WR-564D1)
o 1.8% U 3O8 over 21.5 metres (WR-572D1)
o 10.8% U 3O8 over 4.0 meters (WR-564D3)
o 4.1% U 3O8 over 6.5 metres (WR-610D1)
Illustrative Figures and Further Details
A plan map of the Gryphon A, B, C, D and E series l enses is provided in Figure 1. The inset on Figure 1
shows a schematic cross section of the A, B, C, D a nd E series lenses and their respective inclined
longitudinal section windows (as shaded rectangles) . Figures 2 to 6 provide inclined longitudinal sect ions
of the Gryphon A, B, C, D and E series lenses respe ctively. Figure 7 provides a plan map of the

Further details regarding the Gryphon deposit and t he current mineral resource estimates are provided in
the NI 43-101 Technical Report for the Wheeler Rive r project titled “Preliminary Economic Assessment for
the Wheeler River Uranium Project, Saskatchewan, Ca nada" dated April 8, 2016 with an effective date of
March 31, 2016. A copy of this report is availabl e on Denison’s website and under its profile on SEDAR
at www.sedar.com and on EDGAR at www.sec.gov/edgar.shtml.
Sampling and Assay Procedures
The Company currently reports preliminary radiometr ic equivalent grades ("eU 3O8"), derived from a
calibrated downhole total gamma probe, during its exploration programs and subsequently reports definitive
assay grades following sampling and chemical analysis of the mineralized drill core.
Drill core with anomalous total gamma radioactivity (>300 counts per second) was sampled over 0.5 metre
intervals. Sampling is undertaken on site by splitt ing the core in half, with one half submitted for a nalysis
and the other half retained in the core box for fut ure reference. Uranium assays are performed by the
Saskatchewan Research Council ("SRC") Geoanalytical Laboratories using an ISO/IEC 17025:2005
accredited method for the determination of U 3O8 weight %. Sample preparation involves crushing and
pulverizing core samples to 90% passing -106 microns. The resultant pulp is digested using aqua-regia and
the solution analyzed for U 3O8 weight % using ICP-OES. Core recovery at Gryphon i s typically 100% and
therefore radiometric equivalent U 3O8 grades ("eU3O8") are not required as a substitute for chemical U 3O8
assays. In addition to internal checks by SRC Geoanalytical Laboratories, the Company has rigorous quality
assurance and quality control ("QAQC") procedures including the insertion of standard reference materials,
blanks and field duplicates. The assay data is subj ect to verification procedures by qualified persons
employed by Denison prior to disclosure. For furthe r details on the assay, QAQC and data verification
procedures please see Denison's Annual Information Form dated March 23, 2017 filed under the
Company's profile on SEDAR (www.sedar.com).

Notes:
1. U 3O8 is the chemical assay of mineralized split core samples.
2. Intersection interval is composited above a cut- off grade of 0.05% U 3O8 unless otherwise indicated.
3. Intersection interval is composited above a cut- off grade of 1.0% U 3O8.
4. Composites are compiled using 1.0 metre minimum ore thickness and 2.0 metres maximum waste.
5. As the drill holes are oriented steeply toward t he northwest the true thickness of both the basemen t and unconformity
mineralization is expected to be approximately 75% of the intersection lengths (the basement mineralization is interpreted
to dip moderately to the southeast and the unconformity mineralization is interpreted to be flat-lying).
6. Unconformity intersection.

Notes:
1. U 3O8 is the chemical assay of mineralized split core samples.
2. Intersection interval is composited above a cut- off grade of 0.05% U 3O8 unless otherwise indicated.
3. Intersection interval is composited above a cut- off grade of 1.0% U 3O8.
4. Composites are compiled using 1.0 metre minimum ore thickness and 2.0 metres maximum waste.
5. As the drill holes are oriented steeply toward t he northwest and the basement mineralization is interpreted to dip moderately
to the southeast, the true thickness of the mineralization is expected to be approximately 75% of the intersection lengths.
