NexGen Energy Ltd. ("NexGen" or the "Company")
(
TSX: NXE)
(NYSE: NXE) (ASX: NXG
)
is
pleased to announce
continued
exciting
results
from
the summer drill program
at
the rapidly advancing
PCE.
Step

cumulative >61,000 counts per second (cps)

respectively, located 51 m up
-
dip and 119 m down
-
dip of
PCE’s best hole to date, RK
-
25
-

(Figures 1 and 2)
.
These represent
the best holes
from
the summer
program
to date
and
validate
the
grow
th
in
high
-
grade continuity.
Overall, an upgraded high
-
grade
shoot plunges
a minimum
200 m from RK
-
25
-
254 to RK
-
24
-
222 as
part of
a
n emerging
interpreted
pattern
of
high

grade s
hoots
spaced
70
m apart
(Figures 2 and 3)
.
Depth of the intense high
-
grade in RK
-
25
-
254
,
at just 454.4 m depth,
ranks among the shallowest
intersections of massive uranium ever drilled by NexGen.
Miner
a
lization is open
300 m
up
-
dip
and
completely contained in the
competent basement rock
,
consistent with
Arrow
.
Strong continuity of g
rade
across the mineralized footprint is consistent with
Arrow’s
basement
-
hosted
uranium veins
.
Drilling
is also extending
deeper
wh
ere
strongly developed
alteration and structural disruption
persist
as
key indicators of
additional mineralization
.
Further s
ignificant expansion potential
at PCE
remains
with
mineralization
open
in
most
directions
.
A
total to
21,968.9
m
of the p
lanned
43,000m program
has been drilled
in 2025
.
Since discovery
(see March
11,
2024,
news release),
79
drillholes totalling
53,088.9
m have been completed
(Figure 4)
.
High
-
grade
growth and overall mineralized extent are the focus with many more targets to be tested across th
is rapidly
developing
and growing high
-
grade
system
.
48 of
the
79 drillholes
are
mineralized, including 34
intersecting high
-
grade (>10,000 cps) and 14 intersecting off
-
scale (>61,000 cps).
Leigh Curyer, Chief Executive Officer, commented:
“
This program is delivering exactly what we look for in
a generational uranium discovery
,
basement
-
hosted significant
mineraliz
ed system
,
continuity of
high
-
grade
mineralization
, and growth potential. PCE is evolving in real time into a world
-
class system in its own right
.
NexGen’s highly prospective land package continues to demonstrate exciting results and unmatched
opportunity for Canada to take its place as the number one source
of
uranium in the world.
”
Jason Craven, Vice President, Exploration, commented: “
NexGen’s s
ummer drill program is off to a fantastic
start.
PCE
continue
s
to
deliver
intense high
-
grade uranium
at shallower depths than the world class Arrow
deposit only 3.5km away.
Early summer drilling results
are
build
ing
on e
merging
interpretations
that include
systematic repetition of high
-
grade shoots within the overall mineralized footprint, indicating potential for
significant expansion
at PCE
.
