Denison Mines Corp. Announces Adoption of Indigenous Peoples Policy

Denison operates in various locations across Canada, on lands that are in the traditional territory of Indigenous peoples, including its exploration and evaluation operations in Saskatchewan, which are in regions covered by Treaty 6, Treaty 8 and Treaty 10 encompassing the traditional lands of the Cree, Dakota, Déne, Lakota, Nakota, Saulteaux, and within the homeland of the Métis. As such, Denison's relations with Indigenous People are unique and varied. Denison's flagship Wheeler River Uranium Project is located within the boundaries of Treaty 10, in the traditional territory of English River First Nation, and in the homeland of the Métis.

David Cates, President & CEO of Denison, commented: "I believe Industry has an important role to play in acknowledging, and building awareness of, the history of Indigenous people in Canada and the critical importance of pursuing the objectives of reconciliation. As such, the adoption of an Indigenous Peoples Policy is a notable step in our Company's journey to bring reconciliation to the forefront of what we do and how we do it. This policy is supported by our Board of Directors, on behalf of Denison shareholders, and is welcome amongst all levels of staff within the organization - from the executive team to operational personnel. We are pleased to formalize our Company's approach to Indigenous relations and commit to the development of a continuously evolving Reconciliation Action Plan."

The IPP was developed based on Denison's experiences with, as well as feedback and guidance received from, Indigenous communities with whom the Company is actively engaged. This approach was designed to ensure the IPP appropriately captures a mutual vision for reconciliation. A copy of the IPP (available in English, French, Cree and Déne languages), and other core corporate policies, are available on the Corporate Governance page of Denison's website (www.denisonmines.com).

Overview of Denison's IPP

Denison's IPP reflects the Company's belief that reconciliation is advanced through collaboration with Indigenous peoples and communities to build long-lasting, respectful, trusting and mutually beneficial relationships while aspiring to avoid adverse impacts of Denison's activities and operations.

The IPP identifies 5 key areas of action that will support the ongoing development of a continuously evolving Reconciliation Action Plan ("RAP"): Engagement; Empowerment; Environment; Employment; and Education. Through the RAP, Denison is striving to interweave the principles of reconciliation throughout all areas of the company's operations.

In expressing the Company's intentions in the IPP, Denison carefully considered the standards and principles articulated by The United Nations Declaration on the Rights of Indigenous Peoples and Call to Action 92 (Business and Reconciliation) from Canada's Truth and Reconciliation Commission (the "TRC").

About Reconciliation in Canada

The TRC was established in 2008 and was mandated to reveal to Canadians the complex truth about the history and the ongoing legacy of residential schools in a manner that fully documents the individual and collective harms against Indigenous peoples, and to guide and inspire a process of truth and healing, leading toward reconciliation within Indigenous families, and between Indigenous peoples and non-Indigenous communities, churches, governments, and Canadians generally.

As the TRC summarizes in its reports from 2015, the residential school system was "part of a coherent policy to eliminate Aboriginal people as distinct peoples and to assimilate them into the Canadian mainstream against their will." Operating over a period of almost 130 years, from 1870 to 1997, the Government of Canada estimates that over 150,000 First Nation, Métis, and Inuit students passed through the system.

Reconciliation is described by the TRC as "an ongoing individual and collective process of establishing and maintaining respectful relationships… amongst First Nations, Inuit and Métis former Indian Residential School students, their families, communities, religious entities, former school employees, government and the people of Canada." Amongst many other things, the TRC notes that "a critical part of this process involves repairing damaged trust by making apologies, providing individual and collective reparations, and following through with concrete actions that demonstrate real societal change".

In support of the reconciliation process, the TRC issued 94 Calls to Action - including, but not limited to, those related to child welfare, education, language and culture, health, justice, the rights of Indigenous peoples, missing children and burial information, commemoration, media, sport, and business.
