GREENVALE CONSOLIDATES A MAJOR URANIUM DISTRICT
WITH ACQUISITION OF THE PINE CREEK URANIUM PROJECT
Transformational acquisition includes
the high- grade Thunderball Uranium Deposit, multiple drill-ready targets
and establishes a district-scale 2,466km2
uranium exploration portfolio in a
premier uranium province within the Northern Territory
“This strategic acquisition represents a major step forward in our strategy to establish a
significant uranium portfolio in the Northern Territory and positions Greenvale as a
dynamic uranium growth company” – Greenvale MD Alex Cheeseman
Highlights
Binding term sheet executed to acquire the uranium exploration rights for the Pine
Creek Uranium Project in the Northern Territory held by Patronus Resources Ltd
(ASX:PTN) (‘Patronus’).
The Pine Creek Uranium Project includes multiple granted Exploration Licences and
MiningLeases,covering atotal area of approximately1,250km2
across the Pine Creek
Orogen, a world-class Uranium field with a longstanding history of uranium mining.
The project includes the ultra-high grade Thunderball Uranium deposit, where
recent re-assaying and drilling by Patronus delivered exceptional results including:
TPCDD026 with 10m @ 25,381ppm U3O8 from 145m
TPCRD019 with 10m @12,264ppm U3O8 from 139m; and
TPCRD093 with 13m @7,045ppm U3O8 from 135m.
The Pine Creek Uranium Project includes multiple drill-ready targets and advanced
uranium prospects along a 10km long structural corridor extending from the
Thunderball deposit along the Hayes Creek Fault Zone.
The Hayes Creek Fault Zone runs from the Pine Creek Uranium Project, into the
northernmost tenement of Greenvale’s adjoining Dougals River Project (EL34157),
where the Company is imminently about to commence an airborne geophysics
survey.
The exploration rights more than doubles Greenvale’s strategic position in the Pine
Creek region, creating a continuous, district-scale uranium exploration footprint
covering 2,466km2
, with an exceptional pipeline of exploration opportunities.
Patronus to become a substantial shareholder of Greenvale with a cornerstone
shareholding of 19.6% following completion of the transaction with a commitment
to support the growth and development of the new expanded project.

Greenvale Energy Limited ASX:GRV (“Greenvale” or“the Company”) is pleased to announce that
it has entered into a binding term sheet (subject to conditions) withPatronus ResourcesLtd (ASX:
PTN) to acquire the Uranium Rights1
for the Pine Creek Uranium Project, located in the world-
class Pine Creek Region in the Northern Territory.
The acquisition more than doubles Greenvale’s existing uranium tenure in the
region, establishing a district-scale landholding covering a total of 2,466km2
through the
combination of the Pine Creek Project with Greenvale’s adjoining Douglas River Project (refer to
Figure 1).
Importantly, the acquisition includes the high-grade Thunderball Uranium Deposit, along with an
exceptional portfolio that includes multiple advanced uranium prospects and a pipeline of drill-
ready targets along a highly prospective 10km-long corridor.
The transformational acquisition gives Greenvale an outstanding platform for resource growth
and new uranium discoveries in one of Australia’s most proven uranium provinces, due to its
unique combination of favourable geology, a long mineralising history and established uranium
endowment.
The region hosts extensive Proterozoic-aged sedimentary and metamorphic rocks of the Pine
Creek Orogen, which have undergone multiple tectonic and hydrothermal events that created
pathways for uranium-bearing fluids and concentrated mineralisation.
The Pine Creek Orogen is proven as a uranium district through historical uranium operations and
known, world-class deposits. Its prospectivity is further enhanced by widespread faulting,
basement architecture and associated polymetallic mineral systems (including gold and base
metals).
Despite this highly favourable structural and geological architecture and the region’s proven
ability to host major uranium deposits, the areas covered by the Pine Creek Uranium Project and
Douglas River Project remain relatively under-explored, highlighting exceptional potential for
both near-surface and deeper discoveries at a time where global appetite for nuclear fuel supply
continues to grow year-on-year.
Subject to satisfaction of the conditions, including the ASX determination of whether Chapter 11
of the Listing Rules applies, Greenvale intends to embark on an aggressive, multi-pronged
exploration campaign – initially focused on the high-grade Thunderball Uranium Deposit with a
view to upgrading it to a JORC (2012) Mineral Resource Estimate, while in parallel pursuing the
large number of advanced targets located directly along strike and adjacent to Thunderball.
Most targets are situated along the highly prospective Hayes Creek Fault Zone, which extends
south into Greenvale’s Douglas River Project (EL 34157). Moving forward, the Company will
refer to the combined Pine Creek Uranium/Douglas River Project area as the Thunderball
Uranium Project.

Uranium Rights means the rights granted to Greenvale under the Terms Sheet and a Uranium Rights Agreement (execution of which
is condition precedent) for 20 years (the Uranium Rights Term), whereby Patronus grants Greenvale the exclusive right to conduct
exploration for Uranium on the Tenements, to use, copy and retain copies of historic exploration information in relation to previous
uranium exploration, and subject to Greenvale releasing a future JORC Code compliant Feasibility Study demonstrating that the
proposed project is economically viable, to allow Greenvale, in relation to any Tenement which is an exploration licence or
exploration licence in retention, to apply for one or more mineral leases over the Tenements for development of Uranium projects on
them; or subject to obtaining relevant Authorisations, to require Patronus to transfer any existing mineral lease (or subdivided area
of such mineral lease) which is included in the Tenements free of Encumbrances to Greenvale, subject to the terms and conditions
of the Uranium Rights Agreement.

Greenvale Managing Director, Alex Cheeseman, said:
“This strategic acquisition represents a major step forward in our strategy to establish a
significant uranium portfolio in the Northern Territory and positions Greenvale as a dynamic
Australian uranium growth company.
“This is a logical and complementary growth step that adds significant weight to our
existing uranium portfolio in the NT and Queensland. The Pine Creek Uranium Project brings the
high-grade Thunderball Deposit into our portfolio together with a substantial pipeline of highly
prospective exploration targets immediately adjacent to our existing Douglas River Project.
“Importantly, this consolidates Greenvale’s strategic position across a large and highly
prospective corridor within the Pine Creek Region, allowing us to adopt a holistic exploration
approach across a district-scale land package, with key geological structures traversing both the
Pine Creek and Douglas River Projects. The district-scale exploration footprint we
have established spans over 2,400km2
and positions Greenvale as one of the dominant players
in uranium exploration in the Northern Territory.
“With global uranium demand continuing to strengthen and governments around the world
increasingly recognising the importance of nuclear energy for clean baseload power to support
Greenvale Energy Limited ASX Release
Page | 4
global decarbonisation, we believe the Pine Creek region represents one Australia’s most
compelling uranium exploration and discovery opportunities.
“Importantly, once the conditions are satisfied, we can get on the ground straight away to
commence exploration drilling, leveraging directly off the excellent foundational work
undertaken by Patronus over the past year. As part of the transaction, Patronus will become our
largest shareholder with an ≈19.6% stake, and a commitment to support our growth and
development as an Australian uranium house. As part of this, we look forward to welcoming
Patronus’ Chairman, Rowan Johnston, who will join Greenvale’s Board as a Non-Executive
Director.”
The Pine Creek Uranium Project
The Pine Creek Uranium Project is located approximately 200km southeast of Darwin, Northern
Territory. The project is supported by excellent infrastructure and utilities including a major
transmission line, the Darwin–Alice Springs railway, the Stuart Highway and multiple mining
camps and logistics nodes both along and adjacent to the Stuart Highway.
The project is situated more than 30km west of, and well outside, the Kakadu National Park and
over 15km east of the Litchfield National Park boundary. There are no other National Parks within
the immediate vicinity of the project exploration/mining licences.
Geologically, the project is ideally positioned within the crystalline rocks of the polymetallic Pine
Creek Orogen, known for its world-class, high-grade, unconformity and vein/intrusive-style,
structurally controlled, uranium deposits and mines, such as Ranger, Jabiluka, Rum Jungle and
Coronation Hill/El Sherana (refer to Figure 1).
Within the Pine Creek Uranium Project, additional regional prospects and target areas have
already beenidentified outsideof the mainThunderballUranium Deposit (refer toFigure 2).When
added to the existing target suite at the Douglas River Uranium Project, Greenvale now has a
significant pipeline of exploration prospects ready for immediate advancement.
Figure 3 provides a close-up view of prospectivity at each area around the Thunderball deposit.
The most promising targets are centred around the Hayes Creek Fault Zone and associated
splays, together forming a major regional structural system known for its association with high-
grade uranium deposits such as Thunderball, Bella Rose and Fleur de Lys.
The data packages accessible pursuant to the grant of Uranium Rights comprise various state
and tenement-scale geophysical surveys (including airborne electromagnetics, magnetics,
gravity and radiometrics), and comprehensive datasets of more than 40,000 surface samples
and drillholes across the entire project area, covering alltenements in the package. This includes
drilling data acquired by Thundelarra Exploration Ltd and Oz Uranium (Rockland Resources) at
the Thunderball Uranium deposit.
From these datasets, 8,000 surface samples and 293 drillholes have associated uranium assays,
with 64 surface samples and 111 drillholes returning assays greater than 100ppm U3O8. These
regional scale results are significant as they highlight exploration prospects and target areas that
remain untested for uranium potential. Figure 3 provides a summary of key historical exploration
results at prospects proximal to the Thunderball Uranium Deposit.
Technical Disclosure under Listing Rules 5.12.1 can be seen in full, commencing on page 12,
Appendix 1 provides the full list of all drillholes (Table 1), associated uranium intercepts (Table 2)
and surface samples (Table 3), that are situated within the immediate tenements of interest.

Thunderball Uranium Deposit
The Thunderball Uranium Deposit is hosted by volcanic- and siliciclastic, Palaeoproterozoic-
aged metasediments. The predominant uranium mineral is uraninite, often appearing as poddy
or nuggety mineralisation which appears to locally replace sulphides. Additional mineralisation
comprises minor occurrences of brannerite and coffinite. Alteration in and around the
mineralisation often comprises the haematite-limonite-illite clay “wormrock” alteration texture
(Figure 4) typically seen in the high-grade unconformity deposits of the Athabasca Basin
deposits, Canada.
The deposit itself consists of two mineralised lodes, being the Upper and Lower (Main) Lodes,
dip between 35 and 40 degrees towards the northwest and are hosted within the cherts,
sediments and volcanics of a portion of the South Alligator Group, consisting of the upper and
lower Mount Bonnie and Gerowie Tuff. The Upper Lode is interpreted to be hosted
predominantly by the sediment package of siltstones, carbonaceous shales, sandstones, and
mudstones of the lower Mount Bonnie Formation, while the Lower Lode sits in the Gerowie Tuff.
Thunderball wasdiscovered in 2008by Thundelarra Exploration Ltd (Thundelarra’), following the
identification of strong, uranium-channel anomalies from airborne radiometrics. Subsequent
completion of 82 drillholes between 2008 and 2009, totaling 12,620 metres, resulted in the
estimation of a historical inferred mineral resource, under the earlier JORC (2004) reporting
code, of 829Kt @ 924 ppm U3O8 for a total contained 1.69Mlb U3O82
, using a cutoff of 400 ppm
U3O8.
Cautionary Statement: The inferred mineral resource estimate reported here is entirely historic
in nature and is neither compliant with, nor reported in accordance with the criteria specified in
the JORC (2012) Code (‘JORC Code’). The Competent Person has not done sufficient work to
verify the historic estimate as a mineral resource estimate in accordance with JORC (2012). It is
uncertain that following evaluation and/or further exploration work that the historical estimates
will be able to be reported as mineral resources in accordance with the JORC Code. Further
details can be found in the Cautionary Statement footnote below and in the detailed explanation
sub-header ‘Thunderball MRE and Exploration Results’.
In November 2011, Oz Uranium (wholly owned subsidiary of Rockland Resources (“Rockland”)
entered into a farm-in agreement with PNX Metals Ltd for the Thunderball Deposit and
surrounding tenements. During their tenure, an additional 4 holes were drilled for a total of 733
metres. Rockland also completed disequilibrium and metallurgical studies in 2013 and 2014
with ANSTO Minerals, NSW.
The disequilibrium work confirmed that the Thunderball mineralisation is actually in secular
equilibrium, which means that the uranium in the deposit has not moved on through natural
radioactive decay. Consequently, any downhole gamma data collected for real-time
2
Cautionary Statement
The Thunderball Inferred MRE was previously reported by Thundelarra under the JORC Code 2004 to ASX on 7 February 2011, in an
announcement titled "Thunderball Uranium Maiden JORC Resource". It is acknowledged that:
• the Inferred MRE has not been reported in accordance with the JORC Code 2012;
• a Competent Person has not done sufficient work to disclose the Inferred MRE in accordance with the JORC Code 2012;
• it is possible that following evaluation and/or further exploration work the currently reported estimates may materially change and
hence will need to be reported afresh under and in accordance with the JORC Code 2012;
• after review of the original Thundelarra and PTN exploration results and Inferred MRE, nothing has come to the attention of
Greenvale that causes it to question the accuracy or reliability of PTN reported exploration results or Thundelarrra Inferred MRE for
the Thunderball deposit; but
• Greenvale has not independently validated PTN's exploration results or Thundelarra’s Inferred MRE and therefore is not to be
regarded as reporting, adopting or endorsing those results or estimates.

radiometric assaying correlates well with the corresponding chemical assaysfrom drill samples
at the same depth.
This is a noteworthy technical development as it means that future resource estimations can
utilise a largerproportionof downhole gamma assays, incorporating chemical assaysfor quality
control and assurance purposes, which removes the sampling problems inherent with poddy or
nuggety mineralisation.
Metallurgical testwork was completed involving running a series of diagnostic acid leach tests
over a 24-hour period, at a temperature of 40°C, using sulphuric acid and hydrogen peroxide.
The testwork yielded uranium extractions between 91% and 98%, with ores containing greater
than 1% U3O8 (10,000ppm) returning leach residue grades ofmore than500ppm U3O8, indicating
that optimisation of leach conditions for high-grade samples could further improve overall
uranium extraction.
In 2023, uranium rights were returned to PNX Metals Ltd after the expiry of the 2011 farm-in
agreement with Oz Uranium. Throughout 2024, PNX Metals Ltd merged with Kin Mining NL to
form Patronus Resources Ltd (‘Patronus’). Between 2024 and 2025, Patronus completed a
deposit-wide re-assay program of selected Thundelarra drillholes, followed by a program of
seven diamond core holes totaling 1,278 metres, targeting the Lower (Main) Lode at
Thunderball.
The re-assay program confirmed3
the tenor of several, ultra high-grade intersections, including:
TPCDD026 with 10m @ 2.5% (25,000 ppm) U3O8 from 145m, including 1m @ 16.7%
(167,000 ppm) U3O8 from 148m;
TPCRD019 with 10m @ 1.2% (12,000 ppm) U3O8 from 139m, including 1m @ 17.2%
(172,000 ppm) U3O8 from 139m; and
TPCRD093 with 13m @ 0.7% (7,000 ppm) U3O8 from 135m, including 0.50m @ 14.7%
(147,000 ppm) U3O8 from 146.5m.
The seven-hole diamond drilling program further defined both mineralised lodes, upgraded the
prospectivity for areas of extension down-dip of existing mineralisation and validated historic,
high-grade uranium intercepts. The 2025 drilling returned the following stand-out high-grade
uranium intercepts4
:
TB25DD002 with 0.60m @ 0.24% (2,444 ppm) U3O8 from 183.4m;
TB25DD003 with 1.80m @ 0.20% (1,999 ppm) U3O8 from 74m;
TB25DD004 with 8m @ 0.11% (1,085 ppm) U3O8 from 73m; and 10m @ 2.95% (29,500 ppm)
U3O8 from 87m, including 3m @ 9.7% (97,000 ppm) @ U3O8 from 88m, and 1m @ 2.18%
(21,800 ppm) U3O8 from 96.8m.

Figure 4 – High-grade mineralisation (97,000 ppm U3O8) and ‘wormrock’ alteration between
88 and 91m in hole TB25DD004.
Subsequent geological reviews indicate that the Thunderball mineralisation may have formed as
a result of the combined directional flow of oxidised brines circulating through the overlying
sediments. Concurrently, there may have been ingress of uraniferous fluids (likely originating
from the nearby Cullen Supersuite granites) up through structures such as the Hayes Creek Fault
and related shears, into the South Alligator Group. The mineralisation appears to be replacing a
previously existing massive sulphide lens, predominantly pyrite and thought to be VMS in origin,
indicating that the method for exploration targeting in the area can incorporate techniques used
for exploring for VMS type deposits.
A Pipeline of Compelling Exploration Prospects and Target Areas along the Hayes Creek
Fault Zone
In addition to the Thunderball Deposit, there are currently six additional uranium prospects
identified in the immediate region, including Thunderball Extended, Moonraker, Goldeneye,
Corkscrew, the Bella Rosa Trend and Burrundie Dome (refer to Figure 3).
Thunderball Extended, Moonraker and Corkscrew are all situated along strike to the northeast
and southwest of the Thunderball deposit, approximately 300–400m west of the main Hayes
Creek Fault. This structure is interpreted to be one of two major fault-and-shear systems, the
other being the Bella Rosa Fault approximately 4.5km to the west of Thunderball, with both
systems potentially creating local drag folds in their immediate vicinity.
The Bella Rosa Trend is situated along the Bella Rosa Fault. The Corkscrew Prospect is also
situated at the junction of a NE-SW striking transfer fault which appears to connect the Bella
Rosa and Hayes Creek Fault systems. Similarly, the Goldeneye Prospect is situated on an east-
northeast/west-southwest striking transfer fault to the east of the Hayes Creek fault.
Greenvale Energy Limited ASX Release
Page | 9
The Hayes Creek Fault also continues further to the southwest into Greenvale’s Douglas River
Uranium Project, specifically the northernmost, recently granted5
, exploration licence EL 34157.
In late 2025, Greenvale acquired tenement-scale multispectral data from the Sentinel-2 system
which highlighted multiple helium and radon anomalies showing excellent correlation with both
the position of the Hayes Creek Fault and subtle uranium anomalies in merged, state-wide,
airborne radiometric datasetsacquired from surveys flown at line spacings ofbetween 200m and
4km. The Company is flying airborne geophysics across EL 34157 in June 2026.
Thunderball Extended: The Thunderball Extended Prospect is situated immediately to the southwest
and along strike of the Thunderball Deposit, on a similar radiometric uranium anomaly with
approximately 400m strike length, it straddles the contact between the Mt Bonnie Formation and
Gerowie Tuff.
Historical exploration results include three surface samples6
, collected between 2009 and 2025,
a trenching program completed between 2008 and 2010, comprising four trenches for a total
excavated length of 29.90m, and drilling incorporating 16 Reverse Circulation (RC) and five
diamond core drillholes for a total combined 2,192 drill metres. Standout results7
from trenching
and drilling include:
Trench THTR004 with 2.5m @ 0.6% (6,189 ppm) U3O8 from 6m, including 0.50m @ 3%
(30,544 ppm) U3O8 from 6m;
Drillhole TPCDD001 with 8m @ 0.06% (619 ppm) U3O8 from 26m;
Drillhole TPCDD002 with 4.2m @ 0.08% (796 ppm) U3O8 from 27m; and
Drillhole TPCRC053 with 1m @ 0.3% (2,889 ppm) U3O8 from 83m.
There is an offset between the Thunderball and Thunderball Extended radiometric uranium
anomalies, implying the presence of a northwest/north-northwest trending structure that
separates the two areas. This structure may also have been responsible for producing the slight
rotation of the Thunderball Extended anomaly as seen in Figure 5.
Between 2008 and 2009, Thundelarra drilled five drillholes (08PCRC029, TPCRC055, TPCRC056,
TPCRC057 and TPCRC058) into this offset but clustered on the northeast edge, just to the
southwest of the Thunderball resource. The offset therefore remains underexplored and
prospective for further exploration.
In 2024, PNX/Patronus were granted an Environmental Mining Licence (EML) for drilling at the
Thunderball Deposit. This EML also covered drilling at Thunderball Extended with the initial
objective to test extensions of the Thunderball and Thunderball Extended mineralisation
envelope. In 2025, Patronus only drilled seven holes, all focussed on the Thunderball deposit
only, Thunderball Extended remains drill-ready with approved drill holes under the current EML.

Corkscrew The Corkscrew Prospectissituated approximately3km southwest of the Thunderball
deposit, on a similar strong radiometric anomaly. Work completed to date includes rockchip
samples collected in 2009, with significant assay results including TK650720 with 2.9%
(22,991ppm) U3O8 and TK650719 with 1.4% (13,676ppm) U3O8

.
Between 2008 and 2011, Thundelarra completed 15 RC drill holes, for a total 1,907 metres. No
intercepts were returned above the higher cutoff value of 400 ppm U3O8, however two drillholes
returned mineralised intercepts above the lower cut-off value of 100 ppm U3O8, TPCRC024 with
1m @ 229ppm U3O8 from 80m (no lithology log) and TPCRC078 with 1m @ 163ppm U3O8 from
56m (logged as carbonaceous shale).
Drillhole TPCRC078 is located ~120m northeast, along strike of TPCRC024. Although the
intercepts are low grade, they are still considered to be potentially indicative of thicker, higher-
grade mineralisation and have been interpreted to have missed the radiometric anomalyat depth
as well as the key lithological contact zone.
Goldeneye The Goldeneye Prospect issituated approximately3–4km tothe southwest and along
strike from the Thunderball Deposit. The strong radiometric anomaly has been followed up with
rock chip sampling, returning good indicative mineralisation. The rock chip sampling targeted
discrete uranium-channel anomalies on the airborne radiometrics, similar to the Thunderball
discovery. A total of six rock chip samples were collected in 2009, 2014 and 2024.

The best assay result was collected in 2014 and returned from sample HC0001 with 0.14% (1,427
ppm) U3O8 in “radioactive, ferruginous, breccia zone”, and registering more than 3,000 counts
per second (cps) on a handheld scintillometer.
Between 2008 and 2011, Thundelarra completed seven RC drillholes, for a total 511 metres, two
drill holes intersected mineralisation9
:
TPCRC107 with 1m @ 0.12% (1,226 ppm) U3O8 from 39m; and
TPCRC109 with 6m @ 0.14% (1,441 ppm)U3O8 from44m, including 2m @ 0.4% (4,103ppm)
U3O8 from 44m.
The Goldeneye radiometric anomaly also appears to be offset with the southeastern part of the
anomaly rotated slightly to a more east-west orientation, however this area remains under-
explored. Despite this, the encouraging results from the surface samples and drilling are all
strong indicators that this prospect has further potential and warrants continued exploration.
Moonraker The Moonraker Prospect is situated on the northeastern part of the Thunderball
trend, approximately 1.3km northeast of the Thunderball deposit. Historic exploration results
include 18 rock chip samples collected by PNX Metals (later Patronus) between 2022 and 2025,
on and around a strong radiometric anomaly which aligned with the Hayes Creek Fault Zone on
a northeast-southwest strike (the same as Thunderball and Thunderball Extended). A total of five
drillholes were completed by Thundelarra and Rockland in 2011 and 2014, notable intercepts
include10
:
TPCRC115 with 2m @ 0.09% (943 ppm) U3O8 from 41m, including 1m @ 0.15% (1,510 ppm)
U3O8 from 41m;
TPCRC142 with 4m @ 0.51% (507 ppm) U3O8 from 20m; and
TPCRC143 with 1m @ 0.50% (502 ppm) U3O8 from 45m.
In addition to the airborne radiometrics completed by previous operators, merged state-wide
magnetics and gravity survey data also show the Thunderball, Thunderball Extended and
Moonraker areasto be situated on the north and west edges of weak-tomoderatelymagnetic and
dense, but folded, feature. Geologicalmapping completed by various government, company and
consultant survey programs have suggested that the Thunderball Deposit is situated on the
western limb and/or in the nose of, a north-plunging anticlinal fold.
The magnetics data appear to support this interpretation, while the gravity data remain too
coarse for sufficient resolution. Existing airborne electromagnetic (AEM) data completed in 2009
(the Rum Jungle AEM, Geoscience Australia, program) on a line spacing of 5km and infill of 1km
line spacing, also shows a strong AEM anomaly within the core of this suggested folded feature,
likely produced as a result of the graphitic siltstones and tuffs in the South Alligator Group.
The Moonraker Prospect remains relatively untested and warrants further exploration.
Bella Rosa Trend The Bella Rosa Trend is recognised as another major fault and shear zone,
situated approximately 4.5km to the west of the Hayes Creek Fault Zone. The historic Bella Rose
Uranium deposit is situated at the southwestern end of the system and just outside of the Pine
Creek Uranium Project boundary.
The Bella Rosa Fault eventually appears to intersect with, and is quite likely to be a splay coming
off the main Hayes Creek Fault.
