FISSION URANIUM CORP. ("Fission" or "the Company") is pleased to announce that, as part of its progress towards the Feasibility and Environmental Assessment phases for the PLS project in Saskatchewan, Canada, the Company is continuing to build mutually respectful, transparent and productive relationships with all local rights-holders and stakeholders. This includes the recently-signed Engagement and Capacity agreement with the Clearwater River Dene Nation ("CRDN") (see news release dated March 25, 2021). The agreement strengthens the positive working relationship and establishes a foundation for Fission and CRDN to negotiate a long-term impact benefit agreement if the PLS Project is approved.

The processes covered by the agreement include:

• Prepare, facilitate and coordinate Project information sharing meetings between CRDN and Fission;
• Facilitate and conduct community information meeting on status of the Project;
• Draft, contribute to, review, and provide comments on draft documents leading to Environmental Impact Statement;
• CRDN Comments on draft project description and final project description;
• Joint review and concurrence on target information to be addressed via Engagement Activities; and
• Joint work and collaboration on scope of Engagement Activities and supporting budget.

To achieve the outcomes of these processes in a meaningful and collaborative way, Fission and CRDN have established open lines of communication, and connect regularly by phone, email, and/or meeting. This active, open approach has been paired with a shared communications and commitment tracking log, requested by CRDN, to create a consistent, transparent, and accountable way to raise and address questions, information requests, and concerns, in a timely and efficient manner.            

As part of the Agreement, Fission is funding ongoing engagement work by CRDN, including an Indigenous rights & knowledge study and a traditional land & cultural impact assessment study. These studies will inform CRDN and Fission, and will be incorporated into the ongoing assessment of Fission's Patterson Lake South Project.

Chief Clark commented, "CRDN is not against economic development in our traditional territory and appreciate the steps Fission Uranium is taking on their approach on dealing with the concerns of the Nation. The Clearwater Dene Nation knows the obligation for consultation, accommodation and reconciliation belongs to the governments. We will never have another 'Cluff Lake" in our lands. We welcome companies that want to learn about our Nation and our constitutionally protected rights to the lands like Fission."
