defined by major achievements that bring us to the final stages of delivering the world’s largest high -grade
uranium project, while delivering the most elite standards of health and safety, environmental protection
and social well -being for all of our stakeholders. The exciting new discovery at Patterson Corridor East,
further underscores the exceptional prospectivity of our land package and the long -term growth potential
for the Company. With each milestone, we are not only advancing the Rook I Project but also shaping the
landscape of responsible resource development. As we move toward becoming one of the most strategic
mining companies, our steadfast commitment to sustainable development, elite environmental stewardship,
and genuine community partnerships remains at the core of everything we do.”
Key Highlights from the Report:
Completion of Federal Environmental Assessment Technical Review and Setting of Hearing Dates
NexGen achieved a historic regulatory milestone, successfully completing the Canadian Nuclear Safety
Commission (“CNSC”) Environmental Assessment (“EA”) technical review in November of 2024 – a first for
a greenfield uranium mine and mill in Canada in 20 years. This follows the completion of the Provincial EA
in November 2023. The Company is now preparing for the CNSC Commission Hearing currently scheduled
to be complete in February 2026, and pending a positive EA decision, is ready to immediately commence
construction.
2024 ABEX Community Involvement Award
NexGen was honoured with the 2024 ABEX Community Involvement Award from the Saskatchewan
Chamber of Commerce for its genuine approach to building strong resilient communities through innovative
and inclusive programs that are delivering a positive impact in the region.
Expanded Training and Education Programs
Expansion of the Company’s education and training initiatives included the launch of NexGen’s ‘Pathways
to Your Future’ career development program. This, alongside other NexGen-initiated and funded programs
have equipped over 500 local participants in the Local Priority Area (“LPA”) with essential technical and
workplace skills for careers in uranium mining since 2023.
Local Employment and Procurement Opportunities
Prioritizing communities within the L ocal Priority Area (“L PA”), NexGen exceeded its aspirational
employment and procurement targets, with 82% of Rook I site employees being LPA residents, and 94% of
Rook I cash expenditure awarded to LPA suppliers.
Environmental Performance Through Energy Efficiency
NexGen optimized power generation at the Rook I Project through the implementation of a centralized
power generation system and the installation of a pilot 24-kilowatt solar power system.
Active Environmental Management During Exploration
NexGen minimized its environmental footprint during exploration activity through a single area focused drill
program, resulting in a 73% reduction in overall land disturbance. Additionally, the Company reclaimed 83%
of land disturbed by exploration activity in 2024.
Economic Impact Update
Building on the updated initial capital, and sustaining and operating costs released during 2024, an
economic impact study of the Rook I Project points to the significant scale of its potential positive effects.
The forecasted total economic impact to the Province of Saskatchewan and Canada over the development
and 11-year production period is $37 billion, with an average of 1,400 annual total jobs . Importantly, the
Project is being permitted for a 24-year mine life, underscoring the opportunity for potentially greater long-
term benefits, both economically and socially, well beyond the initial forecast.
Climate-Related Disclosure Alignment (“TCFD”)
NexGen completed a comprehensive TCFD gap analysis, followed by a climate-related risk assessment that
evaluated physical and transition risks over short, medium, and long -term time horizons , ensuring that
climate-related risks and opportunities are effectively integrated into NexGen’s broader risk management
and strategic planning.
The 2024 Report has been prepared in accordance with the GRI Standards, in alignment with the TCFD
and has been reviewed and approved by NexGen's Executive Team, the Sustainability Committee as well
as the full Board of Directors. NexGen will continue to optimize its sustainability reporting in line with the
Company's focus on accountability and transparency.
