Uranium Joint Venture: Badger Lake Drill Programme

Favourable Geologic Conditions for Uranium Mineralisation Confirmed

HIGHLIGHTS:

·    Diamond drilling programme completed with four holes and a total of
1,922 metres drilled.

·    Drilling successfully tested fault structures and analogies of major
deposits.

·    Highly encouraging hydrothermal alteration intersected, including
distinct bleaching and preserved palaeoweathering profiles, confirming the
presence of potential REDOX fronts necessary for uranium precipitation.

·    No elevated radioactivity was encountered, despite the promising
geology and mineralogy encountered.

·    Core samples have been dispatched for comprehensive laboratory
analysis.

 

Sean Wade, Chief Executive Officer of Power Metal Resources PLC commented:

"This initial drill programme has successfully validated our geological models
for Badger Lake. While still early in our exploration, encountering such
geological conditions is a significant milestone for the project. We look
forward to sharing the laboratory results with the market as we plan our next
steps."

DRILL PROGRAMME SUMMARY

Four NQ diameter drill holes (47.6mm core diameter), with a total metreage of
1,922m, were drilled on the Badger Lake Property over the period 2 March - 9
April 2025.  Three holes (BL26-01 to BL26-03) were drilled from a single
central location, and one (BL26-04) was drilled approximately 270m to the
north-north-west, as shown in Figures 1 and 2.

BL26-01 - Drilled to test a combined magnetic low (inferred fault structure),
intersecting both the S-Zone and the inferred Eastern Shear Zone, this hole
was planned for 650m, and 647m were drilled. This hole was targeting
shear/fault-hosted mineralisation and was designed to provide information on
the alteration and geochemistry of the Eastern Shear Zone.

BL26-02 - Drilled to test the inferred Western Shear Zone, the S-Zone and the
overlying anomalous uranium in soil. This hole was planned for 650m, of which
584m was drilled due to the earlier than expected intersection of the target
zone. This hole was targeting shear/fault-hosted mineralisation and was
designed to provide information on the alteration and geochemistry of the
Western Shear Zone.

BL26-03 - Drilled to test for a potential Cigar Lake Analogy between the two
Shear Zones, as well as investigate the S-Zone and the inferred gravity high.
This hole was planned for 400m, but terminated at 305m due to the unconformity
being shallower (250m) than anticipated.

BL-26-04 - Drilled to test for mineralisation at the apex of the Western Shear
Zone and the unconformity. This hole was planned for 400m, and terminated at
386m.

The centralised drilling setup for BL-26-01 to BL-26-03 allowed the programme
to test the two fault structures, the Cigar Lake Anomaly and the S-Zone,
without moving the drill, thereby increasing the programme's efficiency.

The drill programme was carried out by ITL Diamond Drilling Ltd, with
technical services provided by Mercator Geological Services, and helicopter
support from Access Helicopters Ltd. The drilling campaign was staged out of
Big Bear Camp in western Saskatchewan.

A full discussion on previous work on the property, the overlying geochemistry
and the target's structural geology is presented in the Company announcement
of 18 June 2025:

Preliminary Drilling Results

BL-26-01

This inclined (-57°) hole intersected the unconformity at 302.79 metres
down-hole depth equivalent to 253.9m vertical depth or true-depth ("TD"). The
overlying Athabasca sandstone is primarily fine- to medium-grained and pale
brick-red, with minor cross-bedding. A notable zone of desilicification was
observed at 123.00m down-hole (103.2m TD), whilst the lower sandstone column
exhibits weak to moderate illite bleaching (242.0m-275.5m downhole /
203.0m-231.1m TD) and intense maroon haematite alteration approaching the
basement contact.

Beneath the unconformity, a well-developed palaeoweathering profile is
preserved, featuring a heavily hematised Red Zone (302.79m-313.65m downhole /
253.9m-263.1m TD) and a transitional clay-rich Green Zone (313.65m-336.00m
downhole / 263.1m-281.8m TD) dominated by chlorite, illite, and kaolinite. The
basement lithology is primarily augen gneiss with minor pegmatitic sections,
intruded by a series of mafic dykes starting at 501.73 metres downhole (420.8m
TD) and continuing to the end of the hole. The basement was variably
silicified throughout, with the field observations indicating the
Silicification to be late in the alteration sequence.

Structurally, minor faulting and shear zones are clustered immediately below
the unconformity (between 313m and 331m downhole / 262.5m and 277.6m TD), with
no strong evidence of sustained faulting to depth, although annealed
clay-filled fractures were observed. No uranium mineralisation was
encountered, with localised blebby and fracture-fill pyrite (up to 8%)
concentrated between 347.85m and 349.55m downhole (291.7m-293.2m TD),
accompanied by a secondary hydrothermal overprint of chlorite, illite, and
calcite veining within the upper basement.

BL-26-02

This inclined (-57°) hole intersected the unconformity at 316.40 metres
downhole (265.4m TD). The overlying Athabasca sandstone displays variably
bedded pale brick-red to burgundy hues, with significant intermittent
bleaching starting at 277.32m downhole (232.6m TD) and continuing to the
basement contact. Beneath the unconformity, a well-defined palaeoweathering
profile is evident, comprising a Red Zone (316.4m-321.6m downhole /
265.4m-269.7m TD), a transitional Red/Green Zone (321.6m-345.8m downhole /
269.7m-290.0m TD), and a Green Zone (345.8m-387.0m downhole / 290.0m-324.6m
TD).

The basement lithology transitions from an augen gneiss to a structurally
complex granitic and pelitic gneiss sequence, and is similarly silicified, as
with BL2026-01. However, the deeper basement (below 500m downhole / 419.3m TD)
is characterised by significant structural deformation, including multiple
breccias and fault structures infilled with clay, chlorite, and calcite with a
silicified overprint. No uranium mineralisation was identified within the
drillhole.

 

BL-26-03

Drillhole BL2026_03, drilled vertically, encountered the unconformity at a
shallower downhole depth of 251.31 metres. The sandstone showing patchy trace
to moderate bleaching and diagenetic haematite banding, the unconformity is
well preserved, and does not indicate intense hydrothermal alteration. The
basement rocks are dominated by pelitic gneiss, transitioning into
semi-pelitic gneiss and granite. The palaeoweathering profile features a
pronounced Red-Green Zone (251.3m-263.9m downhole) with pervasive haematite
and chloritisation of mafic minerals. Structure in this hole is relatively
weak, mostly limited to open fractures; this weak structural geology and
minimal clay alteration is not supportive of a Cigar Lake model for uranium
mineralisation.

 

BL-26-04

This vertical hole reached the unconformity at 262.30 metres downhole, marked
by 5 centimetres of clay gouge. The sedimentary sequence exhibits patchy
bleaching. The basement is primarily pelitic gneiss grading into granitic
gneiss. A complete, albeit compressed, regolith profile was intersected: a
thin Bleached Zone (262.3m-262.5m), a Red Zone (262.5m-275.9m), and a
Red-Green Zone (275.9m-291.4m). As with the other holes, the basement is
highly silicified and shows moderate fracturing with a notable crackle breccia
zone towards the end of the hole (379.5m), coated with illite, chlorite, and
pyrite.

 

Technical Summary

Above the unconformity, the lower sandstone units exhibit intermittent trace
to moderate illite bleaching and targeted de-silicification overprinting
regional diagenetic haematite. This bleaching is often inferred to be a record
of chemically aggressive, reducing fluids migrating upwards from the basement
structure into the lower sedimentary package, interacting with the oxidised
basinal brines.(1,) (2)

Beneath the unconformity, the drillholes intersected varying extents of the
classic palaeoweathering profile, encompassing haematite-rich Red,
transitional Red-Green, and chlorite-dominant Green zones. This alteration
sequence was most notable in BL26-02, drilled to test the Western Shear Zone
and underlying significant soil geochemical data. Red-green alteration is
noted across the Athabasca Basin, and where it has been subjected to later
hydrothermal alteration in the vicinity of structures, it is inferred to have
provided the chemical contrast crucial for generating uranium deposits. As
such, confirming its presence is a positive outcome of the drilling at Badger
Lake. The highly silicified geology provides scope for brittle faulting, which
can increase the porosity of fault systems, providing pathways for fluid
mixing, and thus aiding in localising mineralising fluids to generate
unconformity-related deposits.(2, 3)

Of note to the prospectivity of the Western Shear Zone is that hole BL26-04
has a distinct, preserved bleached cap directly at the contact between the
Western Shear Zone and the unconformity. This narrow alteration zone can be
inferred to represent a REDOX front mechanism. Such mechanisms are considered
to have formed the high-grade uranium deposits elsewhere in the Athabasca
Basin.

In summary, although no uranium mineralisation was intersected during the
drill programme at Badger Lake, the results speak to a potentially fertile
system.

 

Next Steps

Geochemical, short-wave infrared "SWIR" (for clay mineralogy), petrophysical
(to constrain geophysical models), and petrographic (to understand mineral
assemblages and timing) samples are either at their respective laboratories or
in transit to them for analysis. Analytical work is currently underway across
several facilities; Geochemical samples are being tested at the Saskatchewan
Research Council Geoanalytical Laboratories, whilst SWIR samples are being
processed by the Axiom Exploration Group in Saskatoon. Petrographic samples
are being cut by Vancouver Petrographics prior to analysis at Saint Mary's
University's Mineral Imaging & Analysis Laboratory (Department of Earth
Science); finally, petrophysical samples are undergoing analysis at the Rock
Mechanics Laboratory at the University of Saskatchewan, Saskatoon.

The results of this analysis will be reviewed internally and reported to the
market in due course.

GLOSSARY

 Term                                 Definition
 Alteration (Hydrothermal)            The chemical and physical changes to a rock caused by the passage of hot,
                                      chemically active fluids. In this context, it includes bleaching,
                                      chloritisation, and silicification.
 ANT (Ambient Noise Tomography)       A passive seismic geophysical technique used to image the subsurface, helping
                                      to identify structural features like shear zones.
 Basement / Crystalline Basement      The older, hard, metamorphic and igneous rocks (such as gneiss and granite)
                                      that lie beneath the sedimentary basin.
 Bleaching (Illite Bleaching)         The removal of oxidised iron from a rock by reducing hydrothermal fluids,
                                      resulting in a pale, clay-rich rock. It is a strong indicator of fluid flow.
 Breccia                              Rock that has been fractured into a network of highly interconnected, angular
                                      fragments. These open fractures are often subsequently filled with
                                      hydrothermal minerals like clay and pyrite.
 De-silicification                    The chemical removal of silica (quartz) from a rock by hydrothermal fluids. In
                                      sandstone, this can create soft, porous "sand seams".
 Diagenetic Haematite                 Iron oxide that formed naturally during the regional compaction of the
                                      sedimentary basin, giving the sandstone its background colour.
 Gneiss (Augen, Pelitic, Granitic)    High-grade, banded metamorphic rocks that constitute the primary lithology of
                                      the crystalline basement in this area.
 Palaeoweathering Profile (Regolith)  An ancient soil horizon that developed on the exposed basement rocks before
                                      the overlying sandstones were deposited. In the Athabasca Basin it can be
                                      characterised by distinct Red, Red-Green, and Green clay-rich zones.
 REDOX Front                          An active oxidation-reduction chemical boundary. It occurs where chemically
                                      distinct fluids-such as oxidised basinal brines and reducing basement
                                      fluids-interact and mix.
 Shear Zone                           A zone of structural deformation and faulting in the rock mass. These zones
                                      act as conduits for mineralising fluids.
 Silicification                       The addition of silica to a rock by hydrothermal fluids. It typically
                                      overprints other alteration features.
 True Depth (TD)                      The actual vertical depth of a feature beneath the surface. Because some holes
                                      are drilled at an angle (e.g., -57°), the length of the drill core is longer
                                      than the true vertical depth.
