Subject: RE: Rook I Project – Final Submission of Documents to Support a Licence Application to Prepare Site and Construct a Uranium Mine and Mill

Mr. Moger,

With reference to your letter of June 30, 2023, I can confirm that CNSC staff have performed a sufficiency check of the licensing documents that NexGen has submitted as per section 8.1 of the Uranium Mines and Mills Regulations  (Uranium Mines and Mills Regulations (justice.gc.ca). CNSC staff have determined that what NexGen provided is sufficiently detailed and that now section 8.3 (1) of the regulations is triggered which stipulates:

8.3 (1) The Commission shall render its decision in respect of an application within a time period of 24 months from the day on which the notice is posted in accordance with paragraph 8.2(b)

Note that Section 8.3 (2) of the Regulations contain various exclusions from the 24 month timeframe, which may apply to NexGen. CNSC staff will continue to work closely with NexGen staff to prepare for the next steps of the licensing process.

Sincerely,

Denis Saumure
Commission Registrar
