=&0=& =&1=&is pleased to announce the formation of an exciting partnership with the Clearwater River Dene Nation (CRDN) and Métis Nation – Saskatchewan (MN-S) Local 39, to build and operate a 59-room hotel in La Loche, Saskatchewan. Strategically located to serve the increased demand for local accommodation, particularly from the construction and operations of the Company’s 100% 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 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 build out. 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. read more
