NexGen Announces Expansion of High-Grade Zone at Patterson Corridor East (PCE) and the Completion of 2026 Winter Drill Program
NexGen Announces Expansion of High-Grade Zone at Patterson Corridor East (PCE) and
the Completion of 2026 Winter Drill Program
• Vertical extent of high-grade subdomain increased +33% to 550m with a strike length of
210m
• High-grade extension in RK-26-280c1 with cumulative 4.2m of >10,000 cps including 0.6m
of >61,000 cps
• Continuity of intense mineralization in RK-26-271c1 with cumulative 12.6m of >10,000 cps
including 2.3m of >61,000 cps 80m down plunge of RK-25-256 (5.5m at 21.4% U3O8)
• Progressive high-grade continuity at depth in RK-26-276 with cumulative 11.2m of >10,000
cps including 0.6m of >61,000 cps and RK-26-285 with cumulative 9.0m of >10,000 cps
including 0.7m of >61,000 cps
Vancouver, BC, April 22, 2026 - NexGen Energy Ltd. (TSX: NXE) (NYSE: NXE) (ASX: NXG) ("NexGen"
or the "Company") announces results from the 2026 winter drill program at Patterson Corridor East
(“PCE”) that recently concluded, highlighting significant vertical growth and strong internal continuity of
high-grade mineralization.
Within the mineralized zone of PCE, the high- grade subdomain has now grown to 550 m in vertical extent,
a 33% increase, with a strike length of 210 m. This expansion was primarily driven by hole RK-26-280c1
which returned cumulative 4.2m of >10,000 cps including 0.6m of >61,000 cps at 834m below surface
(Figures 1-3). The hole successfully intersected mineralization 230m down plunge along a high-grade shoot
interpreted to connect with RK-26-271c1 (Figure 4).
Holes RK-26-271c1, RK-26-276, and RK -26-285 returned strong mineralized intercepts between 600 to
700m below surface, where the system remains open for expansion (Figures 1 and 2, Table 1). Results from
RK-26-271c1 include cumulative 12.6m of >10,000 cps including 2.3m of >61,000 cps 80m down plunge of
RK-25-256 (5.5m at 21.4% U 3O8) indicat ing continuity of intense high- grade mineralization (Figure 3) .
Further, the intersections from RK-26-276 (cumulative 11.2m of >10,000 cps including 0.6m of >61,000 cps)
and RK-26-285 (cumulative 9.0m of >10,000 cps including 0.7m of >61,000 cps ) add progressive high-
grade continuity to the base of this growing subdomain.
Drilling 600m to the southeast of PCE along a separate parallel trend, prospective structure and alteration
features are vectoring the Company toward potential repetition of mineralization within the overall PCE
system (Figure 5).
Summer drilling of ~29,200m is schedule to commence the week of May 25, 2026. All samples from 2026
drilling are submitted to the independent Saskatchewan Research Council Geoanalytical Laboratory (SRC),
with results to follow.
Leigh Curyer, Founder & Chief Executive Officer, commented: “ Today’s results from the 2026 winter
program confirm both the scale and growth of PCE continues to advance at pace . Increasing the vertical
extent of the high- grade subdomain by 33 % during the winter program, suggests substantial drilling is
required going forward to fully understand the extent of this mineralized zone. In parallel, drilling focused
on vectoring into additional zones of mineralization will be incorporated into the summer program based on
these winter results.
“With the Rook I P roject commencing construction this summer and the significance of PCE materializing
rapidly, we look forward to future drilling and evaluation of PCE and its potential position in the long -term
profile of NexGen’s uranium portfolio. NexGen is positioned to meet the strong demand for Canadian
uranium for many decades into the future, whilst setting a new industry standard in the safe, efficient and
reliable delivery of offtake to utility customers around the world.”
A total of 12,758.2m of the planned 42,000m has been completed in 2026, focusing on high-grade growth
and expansion of mineralization. Thirteen drill holes totalling 9,131.7 m were dedicated to advancing the
mineralization at PCE and six drill holes totalling 3,626.5m tested the parallel trend. Since discovery (see
news release date March 11, 2024), 115 drillholes totalling 72,464.7m targeted PCE mineralization (Figure
4) with 79 of the 115 drill holes being mineralized, including 54 intersecting high-grade (>10,000 cps)
and 21 intersecting off-scale (>61,000 cps).
