NexGen Announces Regulatory Approval of 2025 Site Program at Rook I Property
NexGen Announces Regulatory Approval of 2025 Site Program at Rook I Property
• 2025 Program includes a temporary exploration airstrip, expansion of exploration camp
facilities and site access road improvements.
• Patterson Corridor East (“PCE”) discovery is expanding rapidly and the 2025 Program will
optimize this growth.
• Incorporating NexGen’s longstanding approach, the 2025 Program will prioritize and
maximize local business opportunities.
Vancouver, BC, June 12, 2025 – NexGen Energy Ltd. ("NexGen" or the "Company") (TSX: NXE) (NYSE:
NXE) (ASX: NXG ) is pleased to announce that the Saskatchewan Ministry of Environment has granted
approval for NexGen’s 2025 Site Program (the “Program”) at its 100% -owned Rook I Property in the
Athabasca Basin, Saskatchewan . The Program includes the establishment of a temporary exploration
airstrip, expansion of the exploration accommodation camp facilities by 373 beds and site access road
improvements.
The Program will commence in the coming weeks and conclude with camp commissioning in Q1 2026. This
program builds on NexGen's disciplined, strategic approach to implementing infrastructure enhancements
required to support the Company's exploration programs at PCE and that forecast across NexGen’s
dominant land package in northwestern Saskatchewan into the future.
The drill results of high-grade basement hosted mineralization discovered at PCE 3.5km east from the Arrow
deposit indicate another significant scale zone “Arrow style” of mineralization is materializing and warrant
these infrastructure enhancements incorporating best practice safety and environmental principles.
Incorporating NexGen's longstanding approach to economic capacity building , the Program will prioritize
Local Priority Area participation, generating new employment and contracting opportunities for Indigenous
and community members, reflecting NexGen's industry leading and genuine approach to local communities.
Leigh Curyer, Founder and Chief Executive Officer, commented: “The 2025 Site Program marks an
exciting strategic milestone for our current and future activities, with key infrastructure improvements that
will optimize safety, environmental protection, and efficiency for our people and our programs . These
infrastructure enhancements create the conditions for a high-performing operational platform capable of
fully evaluat ing the significant resource potential across our Rook I Property . This Program is a direct
reflection of NexGen’s proactive approach to responsible resource development , elite planning and
demonstrates our continued commitment to building lasting value while creating meaningful opportunities
for local Indigenous and community members.”
The Honourable Premier of Saskatchewan Scott Moe, commented: “I congratulate and thank NexGen
for their major investment in Saskatchewan to date. The Rook I Project is one of the most significant projects
across the country and we are keen to see it prioritized by the Government of Canada accordingly. Our
government is proud to approve these infrastructure activities which are well within our jurisdiction and that
are scheduled to commence imminently . NexGen is an example of strategically delivering a generational
opportunity for Saskatchewan to become the world’s leader in the mining of uranium, and I look forward to
working with newly elected Prime Minister Mark Carney to expedite the final Federal approval of this
generational opportunity for Saskatchewan and Canada.”
2025 Site Program Overview
Temporary Exploration Airstrip
• Establishment of a gravel exploration airstrip (<1,000m) on the Rook I Property to enhance health and
safety of workers and accommodate an increase in the regional exploration program , augmenting
emergency response capabilities and human and environmental protection through the reduction of
vehicular transportation of personnel to site.
Expansion of Temporary Exploration Camp Facilities
• Engineering, procurement, and installation of hard -walled modular facilities to accommodate 373
additional beds, ensuring the site can house and service the expanded technical teams and specialized
personnel as exploration activities intensify.
Site Access Improvements
• Improvements to the 13 km Rook I access road to enhance overall worker and equipment safety ,
including widening the road surface to allow for safe, two-way traffic flow.
• Enhanced road base construction to support increased frequency of supply deliveries and specialized
exploration equipment.
NexGen has the most significant land position in Saskatchewan’s southwest Athabasca Basin, where it holds
over 190,000 hectares . From an exploration perspective, t he Company is currently focused on the
continued material growth of mineralization at PCE – located just 3.5 km east of the world -class Arrow
Deposit. Planning is already underway for potential future programs at PCE as the balance of the 2025
drilling program is preparing to recommence in June.

applicable Canadian securities legislation. "Forwa rd-looking information" includes, but is not limited to,
statements with respect to mineral reserve and mineral resource estimates, the 2021 Arrow Deposit, Rook
I Project and estimates of uranium production, grade and long -term average uranium prices, anti cipated
effects of completed drill results on the Rook I Project, planned work programs, completion of further site
investigations and engineering work to support basic engineering of the project and expected outcomes.
Generally, but not always, forward-looking information and statements can be identified by the use of words
