Denison Mines Corp.  (TSX: DML) (NYSE American: DNN) is pleased to announce that it has entered into an exploration agreement with the Ya’thi Néné Lands and Resources Office, Hatchet Lake Denesułiné First Nation, Black Lake Denesułiné First Nation, Fond du Lac Denesułiné First Nation (collectively, the “Athabasca Nations”) and the Northern Hamlet of Stony Rapids, the Northern Settlement of Uranium City, the Northern Settlement of Wollaston Lake and the Northern Settlement of Camsell Portage (collectively, the “Athabasca Communities”) in respect of Denison’s exploration and evaluation activities within the traditional territory of the Athabasca Nations.

The Exploration Agreement expresses the parties’ intention to build a long-term relationship between Denison and the YNLR, Athabasca Nations, and Athabasca Communities.  Denison wishes to conduct and advance its exploration activities in a sustainable manner that respects the Athabasca Nations’ Indigenous rights, advances reconciliation with Indigenous peoples, and provides economic opportunities and other benefits to the Athabasca Communities in an authentic, cooperative and respectful way.

David Cates, Denison’s President and CEO, commented that “This agreement formalizes years of work that Denison and the YNLR have undertaken together in the spirit of collaboration, resulting in several notable achievements, including the renaming of Waterbury Lake’s J Zone deposit to Tthe Heldeth Túé in honour of the Denesułiné territory in which the deposit is located. Our past and present actions demonstrate a mutual willingness to engage in positive business practices that advance reconciliation, and this Exploration Agreement further codifies how the principles expressed in Denison’s Indigenous Peoples Policy will guide our activities in the Nuhenéné into the future.”

Mary Denechezhe, YNLR Board Chair, stated that “Our communities want to participate in and benefit from projects happening on our lands, which historically has not always been the case. This Exploration Agreement will provide certainty to our Basin communities that there will be meaningful engagement on proposed projects and monitoring of exploration activities to ensure the environment and all Treaty Rights are respected. The economic benefits will help to strengthen our communities in the Basin. We acknowledge and respect Denison’s leadership in advancing reconciliation with our communities.”

The Exploration Agreement establishes a progressive and sustainable basis for maintaining a cooperative and mutually beneficial relationship between the parties, which respects the rights and interests of the YNLR, Athabasca Nations and Athabasca Communities, while supporting Denison’s exploration and evaluation activities. The Exploration Agreement includes a framework for predictable information-sharing and permitting processes, environmental protection and monitoring, as well as the sharing of benefits to support community development initiatives. Through this cooperative approach, Denison is able to obtain consent for its exploration and evaluation activities within the Nuhenéné.
