PRESS RELEASE
Peter Ballantyne Cree Nation Withdraws Judicial Review
and
Confirms Support for the Wheeler River Project
Toronto, ON – July 2,
2026. Denison Mines Corp. (“Denison” or the “Company”) (TSX: DML, NYSE American: DNN) reports
that Peter Ballantyne Cree Nation (“PBCN”) has
withdrawn its judicial review application previously filed in the
Court of King's Bench for Saskatchewan related to the Environmental
Assessment approval granted by the Province of Saskatchewan for the
Phoenix In-Situ Recovery (“ISR”) uranium mine
(“Phoenix”). As a result of further engagement with
PBCN, Denison is also pleased to report that PBCN has now formally
provided its consent to and support for the development and
operation of Denison’s Wheeler River Project (“Wheeler
River”) in northern Saskatchewan.
About Wheeler River
Wheeler River is the largest undeveloped uranium project in the
infrastructure-rich eastern portion of the Athabasca
Basin region, in northern Saskatchewan. The project is host to the
high-grade Phoenix and Gryphon uranium deposits, discovered by
Denison in 2008 and 2014, respectively, and is a joint venture
between Denison (90% and operator) and JCU (Canada) Exploration
Company Limited (“JCU”, 10%). In August 2023, Denison
filed a technical report (the “Wheeler River Report”)
summarizing the results of (i) Phoenix FS; and (ii) a cost update
to the 2018 Pre-Feasibility Study for conventional underground
mining of the basement-hosted Gryphon uranium deposit. Based on the
respective studies, both deposits have the potential to be
competitive with the lowest cost uranium mining operations in the
world. Permitting efforts for the planned Phoenix ISR operation
commenced in 2019, culminating in the July 2025 approval of the
Project’s Environmental Assessment (“EA”) by the
Province of Saskatchewan and the February 2026 approval of the
Project’s EA and the grant of the construction licence by the
Canadian Nuclear Safety Commission. Site preparation and early
works construction commenced for Phoenix in March 2026 with first
production targeted for 2028. More information is available in the
technical report titled “NI 43-101 Technical Report on the
Wheeler River Project Athabasca Basin, Saskatchewan, Canada”
dated August 8, 2023 with an effective date of June 23,
2023, and an update to estimated Phoenix initial capital costs
disclosed by press release dated January 2, 2026, copies of which
are available on Denison’s website and under its profile on
SEDAR+ at www.sedarplus.ca and on EDGAR
at www.sec.gov/edgar.
About Denison
Denison is a leading uranium exploration and development company
with interests focused in the Athabasca Basin region of northern
Saskatchewan, Canada. In addition to Denison’s effective 95%
interest in its flagship Wheeler River Project, Denison's interests
in Saskatchewan include a 22.5% ownership interest in the McClean
Lake Joint Venture ("MLJV"), which includes uranium deposits (with
mining at the McClean North deposit having commenced in 2025 using
the MLJV's SABRE mining method) and the McClean Lake uranium mill
(currently utilizing a portion of its licensed capacity to process
the ore from the Cigar Lake mine under a toll milling agreement),
plus a 25.17% interest in the Midwest Joint Venture Midwest Main
and Midwest A deposits, and a 70.55% interest in the Tthe Heldeth
Túé ("THT") and Huskie deposits on the Waterbury Lake
Property. The Midwest Main, Midwest A, THT and Huskie deposits are
located within 20 kilometres of the McClean Lake mill. Taken
together, Denison has direct ownership interests in properties
covering ~457,000 hectares in the Athabasca Basin
region.
Additionally, through its 50% ownership of JCU (Canada) Exploration
Company, Limited (“JCU”), Denison holds interests in
various uranium project joint ventures in Canada, including the
Millennium project (JCU, 30.099%), the Kiggavik project (JCU,
33.8118%) and Christie Lake (JCU, 34.4508%).
In 2024, Denison celebrated its 70th year in uranium mining,
exploration, and development, which began in 1954 with
Denison’s first acquisition of mining claims in the Elliot
Lake region of northern Ontario.
