These agreements reflect Denison's desire to operate its business in a progressive and sustainable manner that respects ERFN rights and advances reconciliation with Indigenous peoples.  The agreements provide ERFN with economic opportunities and other benefits, while establishing a foundation for future collaboration in an authentic, cooperative, and respectful way – designed to cultivate a long-term partnership in support of the Company's activities, including the advancement of the Company's flagship Wheeler River Project, which is currently advancing through a Federal and Provincial Environmental Assessment ("EA") process. 

David Cates, President & CEO of Denison commented, "Many of Denison's interests in the Athabasca Basin region, including our flagship Wheeler River Project, are situated in the traditional territory of ERFN.  We acknowledge and respect the rights of ERFN and are pleased to formalize our Company's effort to work with ERFN in the pursuit of achieving (1) a genuine understanding of the interests of the Nation, and (2) meaningful mutual benefits from Denison's activities.  We feel strongly that the future of the Wheeler River Project will be greatly enhanced by partnering with ERFN – ensuring Indigenous knowledge regarding historical and contemporary land use, environmental knowledge, and environmental stewardship associated with ERFN's connection to this land, are all embedded as essential components of the EA process and project designs.  Together, Denison and ERFN are putting reconciliation principles into action and contributing to the important evolution of Indigenous and industry relationships in the province of Saskatchewan."

Chief Jerry Bernard, of ERFN, added, "We look forward to building on our positive relationship with Denison Mines. The participation and exploration agreements underscore the importance of starting in a good way. That means recognizing and considering ERFN's rights and traditional land and resources uses in all proposed activities on our ancestral lands. The agreements will provide benefits for our community by providing employment and contracting opportunities, annual financial contributions and the ability to help shape project activities to minimize environmental impacts."

Participation Funding Agreement & Letter of Intent

The Participation Agreement and LOI outline a mutually agreeable framework and applicable funding arrangements to facilitate ERFN's participation and engagement in the EA process for the Wheeler River Project – including ERFN's meaningful contribution to Denison's environmental understanding of the Wheeler River Project in a holistic way that respects ERFN's rights and interests.  The LOI also outlines a mutual desire to co-develop a future Shared Prosperity Agreement with respect to the Wheeler River Project, which is intended to reflect a shared vision of how new uranium mining operations in the Athabasca Basin region can prioritize sustainability while also offering new and creative ways to generate wealth and prosperity for all parties involved in the advancement of the Project. 

Exploration Agreement

The Exploration Agreement establishes a framework for a cooperative and mutually beneficial relationship between Denison and ERFN whereby Denison's exploration and evaluation activities are consented to by ERFN and Denison agrees to support ERFN's interests in relation to community development and benefits, environmental protection and monitoring, as well as sustainable and predictable consultation and engagement processes. Through this cooperative approach, the parties seek to continue building a strong and positive foundation for Denison to proceed with its exploration and evaluation activities, in the traditional territory of ERFN, in a manner that is informed by and respects the rights and interests of ERFN.

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 – including combined Indicated Mineral Resources of 132.1 million pounds U3O8 (1,809,000 tonnes at an average grade of 3.3% U3O8), plus combined Inferred Mineral Resources of 3.0 million pounds U3O8 (82,000 tonnes at an average grade of 1.7% U3O8). 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 (10%).

A Pre-Feasibility Study ("PFS") was 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.  Taken together, the project is estimated to have mine production of 109.4 million pounds U3O8 over a 14-year mine life, with a base case pre-tax 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 Phoenix ISR operation is estimated to have a stand-alone base case pre-tax NPV of $930.4 million (8% discount rate), IRR of 43.3%, initial pre-production capital expenditures of $322.5 million, and industry leading average operating costs of US$3.33/lb U3O8.  The PFS is prepared on a project (100% ownership) and pre-tax basis, as each of the partners to the Wheeler River Joint Venture are subject to different tax and other obligations. 

Further details regarding the PFS, including additional scientific and technical information, as well as after-tax results attributable to Denison's ownership interest, are described in greater detail in the NI 43-101 Technical Report titled "Pre-feasibility Study for the Wheeler River Uranium Project, Saskatchewan, Canada" dated October 30, 2018 with an effective date of September 24, 2018.  A copy of this report is available on Denison's website and under its profile on SEDAR at and on EDGAR at

Denison suspended certain activities at Wheeler River during 2020, including the EA process, which is on the critical path to achieving the project development schedule outlined in the PFS.  While the EA process has resumed, the Company is not currently able to estimate the impact of the 2020 suspension on the project development schedule outlined in the PFS, and users are cautioned against relying on the estimates provided therein regarding the start of pre-production activities in 2021 and first production in 2024.
