Contributions and company outcomes

Federal construction licence granted

March 2026 · documented · high materiality

In March 2026 the CNSC issued the company a licence to prepare the site and construct Rook I. It explicitly does not authorize operation, which requires a future licensing decision.

Attribution: Role overlaps event; causation unproven. Curyer was CEO while the company secured the licence; the regulatory process and project development involved the wider team.

Relevance: Material project-permitting milestone; production remains a future stage.

Unlicensed site-preparation violation upheld

2023–2025 · documented · high materiality

In December 2024 the CNSC issued a C$29,080 penalty for constructing two arrays of cased drill holes without a site-preparation licence. NexGen disputed the classification as exploration. In its 2025 determination, the Commission upheld the violation while reducing the penalty to C$11,920 and acknowledged a need for clearer definitions.

Attribution: Role overlaps event; causation unproven. This is a finding against the company while Curyer was CEO; no personal misconduct finding against him was identified.

Relevance: Material project compliance and governance context.

Environmental record

Mount Polley tailings role and documented warning

2012–2015 · documented · high materiality

The BC chief inspector’s report says tailings-facility responsibilities devolved to Moger and other water-management personnel in 2012 and identifies unclear responsibilities and diffuse water-management accountability. The tailings dam breached in August 2014. It records that Moger did not see a concern with an unfilled toe excavation, while acknowledging that such an excavation would reduce the factor of safety. Contemporary reporting also says he warned in a 2013 liaison meeting that rising tailings water required action.

Attribution: Individual involvement documented. The source establishes a specific role and records his account of the excavation, while the investigation describes organizational and engineering factors; it does not establish individual legal culpability for the breach. His reported warning is included as relevant context.

Relevance: The former tailings role and subsequent investigation are material to environmental and project oversight.

2018 professional-title undertaking

In a signed 2018 undertaking with Engineers and Geoscientists BC, Moger agreed that between 2011 and 2016 he used the titles project engineer and mining engineer while not registered with or licensed by the association, that this breached the then Act, and that he stopped promptly when notified. NexGen’s 2024 environmental statement later describes him as a professional engineer; the date and current status of any registration were not independently established.

Attribution: Individual involvement documented. The undertaking records Moger’s own agreed conduct and response. It does not find that this caused the Mount Polley breach, and it does not establish his later or current registration status.

Relevance: Directly relevant to professional-title and licensing diligence for the current permitting role.

Rook I site-preparation violation and later licence

2023–2026 · documented · high materiality

The CNSC determined that NexGen conducted site-preparation work without the required licence, and corrected the penalty to C$11,920. It later granted a construction licence in March 2026; this did not authorize operations. NexGen had contested the classification of the earlier work as site preparation.

Attribution: Role overlaps event; causation unproven. Moger held NexGen’s permitting role during the process; the finding is against NexGen and does not attribute individual misconduct.

Relevance: Directly relevant regulatory context for the current permitting role.
