NexGen Solidifies 100% Ownership of its Entire Land Package
NexGen Solidifies 100% Ownership of its Entire Land Package
• NexGen acquires Rio Tinto’s 10% production carried interest over 39 NexGen- owned mineral
claims in the Southwest Athabasca Basin, including those hosting the Patterson Corridor East (PCE)
discovery.
• NexGen now owns exclusively 100% of its entire portfolio of Projects and Properties which include
Rook I (location of Arrow and PCE deposits), SW1 and SW3.
Vancouver, BC, July 24, 2025 - NexGen Energy Ltd. ("NexGen" or the "Company") (TSX: NXE) (NYSE:
NXE) (ASX: NXG ) is pleased to announce it has exercised its Right of First Refusal to acquire the 10%
production carried interest (PCI) held by Rio Tinto Exploration Canada Inc. (Rio Tinto) over 39 of NexGen’s
mineral claims in the Southwest Athabasca Basin , including those hosting the PCE discovery (Figure 1).
NexGen’s entire portfolio including the Arrow deposit is now 100% owned (Figure 2). Concurrent with its
exercise, NexGen has agreed to match a cash payment offered to Rio Tinto for the interest, the terms of
which are contractually confidential.
Leigh Curyer, Chief Executive Officer, commented: “Given the world class extent, high grade and superior
technical setting of mineralization discovered to date at our two projects, consolidating our portfolio at PCE
and surrounding area to match our 100% ownership in our world-class Arrow deposit, is entirely in line with
our strategic objective of becoming the future leader in uranium production worldwide.
Today, the uranium market is already in a structural deficit. With the world’s leading tech companies recently
committing to the construction of over US$100BN in AI data centres in the US alone - to be predominantly
powered by nuclear energy - the ever-growing need for a safe, secure supply of uranium from sound
jurisdictions is upon us. NexGen’s unmatched uranium endowment, including our flagship Arrow and
developing PCE deposit, together with our large surrounding land package meets that criteria . Today’s
transaction further elevates the realisation of our long -standing strategic objective of becoming the largest
supplier of uranium worldwide.”
History
The PCI entitled Rio Tinto to a 10% undivided interest in future production from the subject claims , carried
through to the commencement of commercial production, and was put in place before NexGen acquired
the land package in 2012. Upon commencement of production, NexGen was entitled to recover 10% of all
prior costs incurred from the effective date of the original agreement, from 75% of Rio Tinto’s 10% share of
production. Following full recovery of those costs, Rio Tinto would have received its full 10% share of
production. A joint venture would have been formed at that time to govern ongoing operations.

Cautionary Note to U.S. Investors
This news release includes Mineral Reserves and Mineral Resources classification terms that comply with
reporting standards in Canada and the Mineral Reserves and the Mineral Resources estimates are made in
accordance with NI 43 -101. NI 43-101 is a rule developed by the Canadian Securities Administrators that
establishes standards for all public disclosure an issuer makes of scientific and techn ical information
concerning mineral projects. These standards differ from the requirements of the Securities and Exchange
Commission ("SEC") set by the SEC's rules that are applicable to domestic United States reporting
companies. Consequently, Mineral R eserves and Mineral Resources information included in this news
release is not comparable to similar information that would generally be disclosed by domestic U.S.
reporting companies subject to the reporting and disclosure requirements of the SEC Accordin gly,
information concerning mineral deposits set forth herein may not be comparable with information made
public by companies that report in accordance with U.S. standards.
Forward-Looking Information
The information contained herein contains "forward-looking statements" within the meaning of applicable
United States securities laws and regulations and "forward -looking information" within the meaning of
applicable Canadian securities legislation. "Forward -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, anticipated
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
such as "plans", "expects", "is expected", "budget", "scheduled", "estimates", "forecasts", "intends",
"anticipates", or "believes" or the negative connotation thereof or variations of such words and phrases or
state that certain actions, events or results "may", "could", "would", "might" or "will be taken", "occur" or "be
achieved" or the negative connotation thereof. Statements relating to "mineral resources" are deemed to
be forward-looking information, as they involve the implied assessment that, based on certain estimates and
assumptions, the mineral resources described can be profitably produced in the future.
Forward-looking information and statements are based on the then current expectations, beliefs,
assumptions, estimates and forecasts about NexGen's business and the industry and markets in which it
operates. Forward -looking information and statements are m ade based upon numerous assumptions,
including among others, that the mineral reserve and resources estimates and the key assumptions and
parameters on which such estimates are based are as set out in this news release and the technical report
for the property , the results of planned exploration activities are as anticipated, the price and market supply
of uranium, the cost of planned exploration activities, that financing will be available if and when needed
and on reasonable terms, that third party contr actors, equipment, supplies and governmental and other
approvals required to conduct NexGen's planned exploration activities will be available on reasonable terms
and in a timely manner and that general business and economic conditions will not change in a material
adverse manner. Although the assumptions made by the Company in providing forward-looking information
or making forward-looking statements are considered reasonable by management at the time, there can be
no assurance that such assumptions will prove to be accurate in the future.
Forward-looking information and statements also involve known and unknown risks and uncertainties and
other factors, which may cause actual results, performances and achievements of NexGen to differ
materially from any projections of results, performances and achievements of NexGen expressed or implied
by such forward -looking information or statements, including, among others, the existence of negative
operating cash flow and dependence on third party financing, uncertainty of the availability of additional
financing, the risk that pending assay results will not confirm previously announced preliminary results,
conclusions of economic valuations, the risk that actual results of exploration activities will be different than
anticipated, the cost of labour, equipment or materials will increase more than expected, that the future
price of uranium will decline or otherwise not rise to an economic level, the appeal of alternate sources of
energy to uranium -produced energy, that the Canadian dollar will strengthen against the U.S. dollar, that
mineral resources and reserves are not as estimated, that actual costs or actual results of reclamation
activities are greater than expected, that changes in project parameters and plans continue to be refined
and may result in increased costs, of unexpected variations in mineral resources and reserves, grade or
recovery rates or other risks generally associated with mining, unanticipated delays in obtaining
governmental, regulatory or First Nations approvals, risks related to First Nations title and consultation,
reliance upon key management and other personnel, deficiencies in the Company's title to its properties,
uninsurable risks, failure to manage conflicts of interest, failure to obtain or maintain required permits and
licences, risks related to changes in laws, regulations, policy and public perception, as well as those factors
or other risks as more fully described in NexGen's Annual Information Form dated March 3, 2025 filed with
