PRESS RELEASE
DENISON ANNOUNCES FILING OF TECHNICAL REPORT
FOR WHEELER RIVER PFS
Toronto, ON – October 30, 2018 Denison Mines Corp. (“Denison” or the “Company”) (DML: TSX, DNN: NYSE MKT) today announces that it filed a technical report under Canadian Securities Administrators' National Instrument 43-101 Standard of Disclosure for Mineral Projects for its 90% owned Wheeler River Project in Saskatchewan titled "Pre-feasibility Study for the Wheeler River Uranium Project, Saskatchewan, Canada" dated October 30, 2018 with an effective date of September 24, 2018.
The technical report is posted on the Company's website at www.denisonmines.com and is available under its profile on SEDAR at www.sedar.com and on EDGAR at www.sec.gov/edgar.shtml. This report supports the disclosure made by the Company in its news release dated September 24, 2018 (the "News Release") and there are no material differences contained in the technical report from the information previously disclosed in the News Release.
As outlined in the News Release, the PFS considers the potential economic merit of co-developing the Phoenix and Gryphon deposits. The high-grade Phoenix deposit is designed as an In-Situ Recovery (“ISR”) mining operation, with associated processing to a finished product occurring at a plant to be built on site at Wheeler River. The Gryphon deposit is designed as an underground mining operation, utilizing a conventional long hole mining approach with processing of mine production assumed at Denison’s 22.5% owned McClean Lake mill.
Taken together, the project is estimated to have mine production of 109.4 million pounds U 3 O 8 over a 14-year mine life, with a base case pre-tax Net Present Value (“NPV”) of $1.31 billion (8% discount rate), Internal Rate of Return (“IRR”) of 38.7%, and initial pre-production capital expenditures of $322.5 million. The base-case economic analysis assumes uranium sales are made at UxC Consulting Company, LLC's ("UxC") annual estimated spot price for mine production from the Phoenix deposit (from ~US$29/lb U 3 O 8 to US$45/lb U 3 O 8), and a fixed price for mine production from the Gryphon deposit (US$50/lb U 3 O 8).
Using the same price assumed for the project's 2016 Preliminary Economic Assessment ("2016 PEA"), a fixed uranium price of US$44/lb U 3 O 8 ("PEA Reference Case"), the PFS produces a combined pre-tax project NPV of $1.41 billion – representing roughly 275% of the $513 million pre-tax project NPV estimated in the 2016 PEA.

●
Selection of ISR mining method for high-grade Phoenix deposit – Following the completion of the 2016 PEA, the Company evaluated 32 alternate mining methods to replace the high-cost Jet Bore Mining System (“JBS”) assumed for the Phoenix deposit in the 2016 PEA. The suitability of ISR mining for Phoenix has been confirmed by significant work completed in the field and laboratory – including drill hole injection, permeability, metallurgical leach, agitation, and column tests. Results demonstrate high rates of recovery in both extraction (+90%) and processing (98.5%) following a simplified flow sheet that precipitates uranium directly from the uranium bearing solution (“UBS”), without the added costs associated with ion exchange or solvent extraction circuits.
●
Novel application of established mining technologies – Given the unique geological setting of the Phoenix deposit, straddling the sub-Athabasca unconformity in permeable ground, the project development team has combined the use of existing and proven technologies from ISR mining, ground freezing, and horizontal directional drilling to create an innovative model for in situ uranium extraction in the Athabasca Basin. While each of the technologies are well established, the combination of technologies results in a novel mining approach applicable only to deposits occurring in a similar geological setting to Phoenix – which now represents the first deposit identified for ISR mining in the Athabasca Basin.
●
Environmental advantages of ISR mining at Phoenix – The Company’s evaluation of the ISR mining method for Phoenix has also identified several significant environmental and permitting advantages, namely the absence of tailings generation, the potential for no water discharge to surface water bodies, and the potential to use the existing Provincial power grid to operate on a near zero carbon emissions basis. In addition, the use of a freeze wall, to encapsulate the ore zone and contain the mining solution used in an ISR operation, eliminates common environmental concerns associated with ISR mining and facilitates a controlled reclamation of the site. Taken together, the Phoenix operation has the potential to be one of the most environmentally friendly mining operations in the world. Owing largely to these benefits, consultation with regulatory agencies and stakeholder communities, to date, has been encouraging regarding the use of ISR mining.
The PFS has been completed in accordance with NI 43-101, Canadian Institute of Mining, Milling and Petroleum (CIM) standards and best practices, as well as other standards such as the AACE Cost Estimation Standards.
Wheeler River Project
The Wheeler River project is the largest undeveloped uranium project in the eastern portion of the Athabasca Basin region in northern Saskatchewan, Canada. The project is situated in close proximity to important regional infrastructure, including the Provincial electrical transmission grid and an all-season Provincial highway. Since Denison became the operator of the project in 2004, two high-grade uranium deposits have been discovered and now account for combined Mineral Reserves and Mineral Resources (100% Basis) as follows:
●
Probable Mineral Reserves of 109.4 million pounds U3O8

Deposit | Classification | Tonnes | Grade | Lbs U3O8
Phoenix | Probable | 141,000 | 19.1% | 59.7 million
Gryphon | Probable | 1,257,000 | 1.8% | 49.7 million
Total | Probable | 1,398,000 | 3.5% | 109.4 million

Notes:
(1)
Reserve statement is as of September 24, 2018;
(2)
CIM definitions (2014) were followed for classification of mineral reserves;
(3)
Mineral reserves for the Phoenix deposit are reported at the mineral resource cut-off grade of 0.8% U 3 O 8. The mineral reserves are based on the block model generated for the May 28, 2014 mineral resource estimate. A mining recovery factor of 85% has been applied to the mineral resource above the cut-off grade;
(4)
Mineral reserves for the Gryphon deposit are estimated at a cut-off grade of 0.58% U 3 O 8 using a long-term uranium price of USD$40/lb, and a USD$/CAD$ exchange rate of 0.80. The mineral reserves are based on the block model generated for the January 30, 2018 mineral resource estimate. The cut-off grade is based on an operating cost of CAD$574/tonne, milling recovery of 97%, and 7.25% fee for Saskatchewan royalties;
(5)
Mineral reserves include diluting material and mining losses;
(6)
Mineral reserves are stated at a processing plant feed reference point;
(7)
Numbers may not add due to rounding.
●
Indicated Mineral Resources (inclusive of Reserves) of 132.1 million pounds U 3 O 8 (1,809,000 tonnes at an average grade of 3.3% U3O8); plus
●
Inferred Mineral Resources of 3.0 million pounds U 3 O 8 (82,000 tonnes at an average grade of 1.7% U3O8).
The PFS does not include any economic analysis based on estimated Inferred Mineral Resources.
The project is a joint venture between Denison (90% and operator) and JCU (Canada) Exploration Company Limited ("JCU") (10%).
