NEXGEN ESTABLISHES PARTNERSHIP WITH INDIGENOUS COMMUNITIES TO DEVELOP A NEW HOTEL IN LA LOCHE TO SUPPORT THE COMMUNITIES AND ROOK I PROJECT

NexGen Energy Ltd. has formed an exciting partnership with the Clearwater River Dene Nation (CRDN) and Metis Nation -- Saskatchewan (MN-S) Local 39, to build and operate a 59-room hotel in La Loche, Sask. Strategically located to serve the increased demand for local accommodation, particularly from the construction and operations of the company's 100-per-cent-owned Rook I project as well as other regional needs, the hotel will drive economic growth including the creation of 36 local full-time roles. NexGen's Rook I project will generate generational economic and social benefits to the region as it becomes an economic hub in Northern Saskatchewan.

• The 59-room hotel with conference centre, restaurant, cultural heritage centre and playground will meet growing regional accommodation demand and create 36 local full-time roles.
• Partnership model highlights NexGen's long-standing collaborative approach with indigenous communities.
• NexGen driving regional economic growth and community benefits in Northern Saskatchewan with development of the Rook I project.

The partnership is financially backstopped by NexGen and structured such that the CRDN and MN-S Local 39 will be full owners and operators of the hotel once in operation in July, 2027. The CRDN and MN-S have applied for federal grant funding to support the local infrastructure buildout. NexGen has appointed 3Twenty Modular as the builder of the hotel so that NexGen maintains its sole focus on the ramp up of the construction phase of its Rook I project following an approval decision from the CNSC in February, 2026. This model builds on the success of previous innovative collaborations, including the establishment by NexGen of the indigenous-owned aggregate crushing company which is providing significant aggregate material to the Rook I project and is responsible for the creation of 16 new local full-time roles.

Leigh Curyer, founder and chief executive officer of NexGen, commented: "This partnership with the CRDN and MN-S Local 39 truly exemplifies NexGen's commitment to meaningful collaboration for community empowerment and is a testament to over a decade of genuine and transparent engagement. The hotel initiative is one example of NexGen's industry leading approach to the successful resource development that incorporates the core philosophy of creating outcomes beyond the Rook I project.

The hotel is a central piece of local infrastructure which will host significant regional events and support the generation of additional new businesses covering retail, banking and community services into the region providing meaningful employment and increased economic activity for generations to come.

On final federal approval, the Rook I project will create more than 1,400 total direct annual jobs across Saskatchewan during construction and the first 11 years of production."

The honourable premier of Saskatchewan, Scott Moe, commented: "This is an incredibly important milestone for the Clearwater River Dene Nation, MN-S Local 39 and the entire Northern Saskatchewan region. The partnership to build and operate a new 59-room hotel in La Loche is a strong example of what meaningful, long-term collaboration can achieve. This model puts lasting benefits directly into the hands of the community and reflects the kind of forward-thinking investment that leads to generational impact. It also demonstrates what's possible when we work together with shared purpose and respect. Congratulations to NexGen and their community partners. This is a proud moment that will help shape a vibrant, resilient future for La Loche and the wider region."
