ASX Announcement

24 June 2026

NEW HIGH-GRADE URANIUM DISCOVERY IDENTIFIED AT PLS PROJECT

Perth, Australia - Paladin Energy Ltd (ASX:PDN, TSX:PDN, OTCQX:PALAF) (“ Paladin” or the “ Company”)

announces it has successfully completed its 2026 winter drilling program at the Patterson Lake South ( PLS) high-

grade uranium project, located in the Athabasca Basin region of Saskatchewan, Canada, with the discovery of a new

body of high-grade uranium mineralisation, the Atlas discovery.

Highlights

 High-grade uranium mineralisation has been intersected 3.5km south of Paladin’s Triple R deposit and 4.5km

southwest of Saloon East.

 Eight (8) exploration drillholes were collared, with seven intersecting significant uranium mineralisation at the

new Atlas discovery, totalling 2,408m.

 Key winter 2026 intercepts at Atlas include:

o PLS26-708B (discovery drillhole): 17.5m of total composite uranium mineralisation across three

intervals, the largest being 8.0m averaging 1.75% U 3O8, including 3.0m averaging 4.25% U 3O8 from

190.0m to 193.0m

o PLS26-718: 21.5m of total composite uranium mineralisation across two intervals, the largest being

14.5m averaging 1.70% U3O8, including 5.5m averaging 2.86% U3O8 from 194.5m to 200.0m

o PLS26-722: 30.0m of total composite uranium mineralisation across seven intervals, the largest being

11.0m averaging 1.79% U3O8, including 5.0m averaging 2.94% U3O8 from 189.0m to 200.0m

 The Atlas discovery remains open along strike and at depth.

After a large-scale ground geophysical survey at the PLS project from February to June 2025, a highly prospective

anomaly was identified within the broader Saloon Trend, 4.5km southwest of anomalous uranium concentrations

identified at Saloon East. Drill testing of this geophysical anomaly intersected new high-grade basement-hosted

uranium mineralisation commencing approximately 160m downhole in what was subsequently named the Atlas

discovery. A total of 2,408m of drilling has been completed at Atlas, and the discovery remains open along strike and

at depth.

The 2026 winter drilling program also targeted resource conversion and extension drilling at the Triple R deposit and

further drilling on the Saloon Trend, along with regional exploration. Following a short seasonal break, drills and field

crews were re-mobilised to the PLS project in May to continue work at Atlas as well as other priority target areas. All

currently identified trend targets (including Atlas) are land-based, allowing drilling activities to continue uninterrupted

throughout the summer months.

Paladin CEO Paul Hemburrow said: “ The Atlas discovery is a significant and very positive result for Paladin’s

exploration strategy and builds on our success in 2025 with the Saloon East discovery. The initial Atlas results

reinforce the potential of the PLS project across multiple prospective mineral corridors and demonstrates the

effectiveness of the Company’s systematic targeting approac h that is now focused on the land-based trends

surrounding Patterson Lake. We also continue drilling the Triple R deposit to upgrade confidence in that resource,

focusing on resource to reserve conversion to add value to the life of the mine.”

Overview of Atlas Drill Program

The Saloon Trend is a linear, multi-kilometre long, southwest-northeast trending structural zone up to 1km in width,

that is parallel to and located 3.5km south of the shear zones that host the Triple R deposit within the Patterson Lake

corridor (Figure 1).

Since 2024, the Saloon Trend has represented a principal exploration focus for the Company, with anomalous

uranium geochemistry and associated structural disruption defined over an approximately 8km strike extent. Drill

targeting for the 2026 campaign was further refined following completion of a large-scale ground geophysical survey

from February to June 2025, which identified high priority geophysical anomalies along the trend.

Although the second drillhole of the 2026 program, PLS26-708, was discontinued at a depth of 152.0m due to

challenging ground conditions, a follow-up drillhole, PLS26-708A, successfully intersected three zones of uranium

mineralisation before also being discontinued at a depth of 206.0m due to similar ground conditions. The final re-

collar, PLS26-708B, was completed as planned and intersected 17.5m of composite uranium mineralisation across

three discrete intervals, including 8.0m grading 1.75% U 3O8 from 188.0m to 196.0m. This result underpinned the

Atlas discovery.

Prior to a seasonal break of drilling activities in May, five additional drillholes were completed at Atlas, bringing the

total to 2,408m drilled (Figure 2 and Table 1). Uranium mineralisation was intersected in seven of eight Atlas drillholes,

hosted within steeply southeast-dipping stacked shear zones, currently defined over approximately 60m of strike

length and at vertical depths ranging from 120m to 260m below surface (Figure 3). The Atlas discovery remains open

along strike and at depth, representing one of the main targets for the summer drill program.

In addition to Atlas, eight drillholes were completed at Saloon East, 3.5km southeast of Triple R, totalling 2,759m.

Samples for uranium assay from the Saloon East drillholes are currently being processed at the Saskatchewan

Research Council Geoanalytical Laboratory.

JORC Code, 2012 Edition – Table 1

Section 1 Sampling Techniques and Data

(Criteria in this section apply to all succeeding sections.)

Criteria JORC Code explanation Commentary

Sampling

techniques

 Nature and quality of sampling (e.g. cut channels, random chips, or

specific specialised industry standard measurement tools appropriate

to the minerals under investigation, such as down hole gamma

sondes, or handheld XRF instruments, etc). These examples should

not be taken as limiting the broad meaning of sampling.

 Include reference to measures taken to ensure sample representivity

and the appropriate calibration of any measurement tools or systems

used.

 Aspects of the determination of mineralisation that are Material to the

Public Report.

 In cases where ‘industry standard’ work has been done this would be

relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1

m samples from which 3 kg was pulverised to produce a 30 g charge

for fire assay’). In other cases, more explanation may be required,

such as where there is coarse gold that has inherent sampling

problems. Unusual commodities or mineralisation types (e.g.

submarine nodules) may warrant disclosure of detailed information.

 Drilling related to this release was carried out using a conventional

coring drill rig.

 Drill core that returned handheld RS-121 scintillometer readings equal

to or greater than 300 counts per second (cps) relative to a

background of 100 counts per second was marked for sampling and

split in half along the core axis into 50-centimetre core-length

samples.

 One half of the core was placed into a labelled sample bag and sent

for geochemical analysis and weight percent (wt%) U₃O₈ assay, while

the other half remained in the core box as a permanent record.

 Core samples for geochemistry and U ₃O₈ assay were crushed to 60%

passing −2 mm, and a 100 g to 200 g sub-sample was split using a

riffle splitter. The sub-sample was then pulverized to 90% passing

106 μm using a standard puck-and-ring grinding mill. An aliquot of the

pulp was digested in a concentrated mixture of HNO₃:HCl in a hot

water bath for one hour and was then diluted with de-ionized water.

The samples were analysed using a Perkin Elmer ICP-OES

instrument.

Drilling

techniques

 Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air

blast, auger, Bangka, sonic, etc) and details (e.g. core diameter, triple

or standard tube, depth of diamond tails, face-sampling bit or other

type, whether core is oriented and if so, by what method, etc).

 All drilling reported in this release was completed using a Zinex A5

core drill.

 Drillholes PLS26-708 and 708A were drilled entirely as NQ diameter

core (47.6mm).

 Drillholes PLS26-708B and 711 began as NQ diameter core which

was reduced to BQ diameter (36.4 mm) coring during drilling due to

poor ground conditions.

 PLS26-716, 718, 720 and 722 began as HQ diameter (63.5 mm) core

at the top of bedrock which was reduced to NQ diameter core once

ground conditions improved.

 Drill core is orientated by the logging geologist, with orientation marks

provided by an IMDEX ACTIII.

Drill sample

recovery

 Method of recording and assessing core and chip sample recoveries

and results assessed.

 Measures taken to maximise sample recovery and ensure

representative nature of the samples.

 Drill core was logged geotechnically on a run-by-run or ISRM rock

strength basis and included the number of naturally occurring

fractures, mechanical fractures, intact core recovery, rock quality

designation (RQD), ISRM rock strength, longest stick, and

radioactivity measured in cps.
