NexGen Announces Expansion of High-Grade Subdomain at Patterson Corridor East (PCE) and Commencement of 2026 Exploration Program Totalling 45,500 Meters

PCE Expansion:

2026 Drilling Program Commencement:

Vancouver, BC, January 15, 2026 - NexGen Energy Ltd. ("NexGen" or the "Company") (TSX: NXE) (NYSE: NXE) (ASX: NXG) is pleased to announce the concluding holes of the 2025 PCE program and the commencement of the 2026 Exploration Program.

2025 PCE

Final drill holes of the 2025 PCE program delivered continued expansion of mineralization with high-grade growth and assessment of extents advancing significantly since the Company's last scintillometer report (see news release dated August 28, 2025). The primary high-grade subdomain grew to 412 m in vertical extent (increase of 77 m) and a strike length of 210 m. An additional high-grade subdomain is developing with hole RK-25-257 intersecting local off-scale (>61,000 cps) at the base of the currently outlined mineralized footprint, indicating significant expansion potential at depth (Figures 1-4, Table 1). 


The overall mineralized footprint expanded to 620 m (increase of 20 m) of strike length and 700 m (increase of 100 m) of vertical extent, remaining open in most directions. Step out testing has provided critical information regarding extents of the system and opportunities for continued growth.

Internal continuity within the subdomain was most recently highlighted by RK-25-271 with 5.8 m of cumulative high-grade (>10,000 cps) and 0.8 m of off-scale (>61,000 cps) that increases the mineralized zone in the lower half of this subdomain (Figure 3, Table 1).  Hole RK-25-271 is located 65 m down-dip from hole RK-25-256 (see news release dated December 1, 2025) which returned 5.5 m at 21.4% U3O8, including 2.5 m at 46.1% U3O8 and 0.5 m at 74.8% U3O8.

The 2025 drilling program successfully completed 35,366.2 m, the largest reported in the Athabasca Basin in 2025. Since discovery (see news release date March 11, 2024), 102 drillholes totalling 69,042.2 m have been completed (Figure 1). A dual focused approach was taken in 2025 to both grow and define multiple high-grade subdomains as well as expand the overall mineralized footprint. To date, 67 of the 102 drill holes are mineralized, including 45 intersecting high-grade (>10,000 cps) and 17 intersecting off-scale (>61,000 cps).

2026 Exploration Program Commencement

Advancement of PCE mineralization with 42,000 m of drilling (Figure 5):

Drilling activity will primarily focus on high-grade growth and the continued expansion of the mineralized footprint. At least eight (8), 200 m spaced tests will also investigate for repetition of basement-hosted mineralization within the same hydrothermal system approximately 600 m southeast of the PCE discovery.

Regional drilling of 3,500 m at SW3 (Figure 6):

An inaugural, drill program will take place on the SW3 land package with regional greenfield testing of highly prospective target areas. This marks the first drilling on any SW3 mineral claims by NexGen and an exciting step in the direct investigation of geophysical anomalies identified. The SW3 package is one of the three core packages NexGen owns 100% of in the southwest Athabasca Basin and is situated 20 km southeast of the SW2 package which hosts the Rook I Project.

Leigh Curyer, Chief Executive Officer, commented: "We are extremely pleased with the 2025 outcomes from the 2025 drill program at PCE that delivered on our dual-purpose objectives of expanding the overall mineralized footprint and expand the high-grade subdomain within it. These results systematically outline mineralization that continues to deliver growth and strong continuity, characteristics synonymous with Arrow deposit 3.5 km west. The 2025 drill program has rapidly advanced this new discovery, while underscoring the tremendous prospectivity of NexGen's 100% owned dominant land holdings which is driving the expanded activity in 2026.  The 2026 program is designed to continue the dual track focus at PCE and in parallel, test for a repetition of PCE within the same system.  In addition, drilling for the first time at our SW3 property is a reflection of the south western section of the Athabasca Basin world class prospectivity.

At a pivotal moment for global energy security, nuclear power is being recognized as an indispensable pillar for reliable, clean, cost efficient energy. The NexGen team is laser focused on concluding the final Federal permitting and licensing for the Rook I Project and immediately advancing through construction into production whilst simultaneously advancing the exciting PCE discovery and other high priority targets.

Jason Craven, Vice President, Exploration, commented: "Last year's highly transitional and successful program positions NexGen to enter 2026 with an even deeper understanding of this broad and growing high-grade system. A multitude of targets remain to be tested as we continue to systematically advance PCE with a dual priority track of expanding both the high-grade subdomains as well as the overall mineralized system. The comprehensive 2026 program strategically positions all three land packages on an exciting path toward expansion of PCE as well as additional discoveries as NexGen works to sustainably supply the world with uranium in the face of mounting and persistent deficits."

Technical Disclosure*

All technical information in this news release has been reviewed and approved by Jason Craven, NexGen's Vice President, Exploration, a qualified person under National Instrument 43-101.

Natural gamma radiation in drill core reported in this news release was measured in counts per second (cps) using a Radiation Solutions Inc. RS-125 gamma spectrometer. The reader is cautioned that total count gamma readings may not be directly or uniformly related to uranium grades of the rock sample measured; they should be used only as a preliminary indication of the presence of radioactive minerals.

A technical report in respect of the FS is filed on SEDAR (www.sedarplus.ca) and EDGAR (www.sec.gov/edgar.shtml) and is available for review on NexGen Energy's website (www.nexgenenergy.ca).

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 technical 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 Reserves 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 Accordingly, 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 made 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 contractors, 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 6, 2024 filed with the securities commissions of all of the provinces of Canada except Quebec and in NexGen's 40-F filed with the United States Securities and Exchange Commission, which are available on SEDAR at www.sedarplus.ca and Edgar at www.sec.gov .

Although the Company has attempted to identify important factors that could cause actual results to differ materially from those contained in the forward-looking information or statements or implied by forward-looking information or statements, there may be other factors that cause results not to be as anticipated, estimated or intended. Readers are cautioned not to place undue reliance on forward-looking information or statements due to the inherent uncertainty thereof.


There can be no assurance that forward-looking information and statements will prove to be accurate, as actual results and future events could differ materially from those anticipated, estimated or intended. Accordingly, readers should not place undue reliance on forward-looking statements or information. The Company undertakes no obligation to update or reissue forward-looking information as a result of new information or events except as required by applicable securities laws.
