Acquisition of Napperby Uranium Resource and High-Grade Exploration Projects
Strategic acquisition grows global Uranium Resource to 169 Mlb U3O8 and consolidates Central Australian portfolio.
KEY HIGHLIGHTS
-
Strategic acquisition of complementary Australian uranium projects from Core Lithium Ltd (ASX: CXO) increases the Company’s global Mineral Resources to 169 Mlb U3O8.
-
Assets are located in the Northern Territory (NT) and South Australia (SA), two highly supportive, established uranium mining jurisdictions.
-
Napperby uranium project (NT) contains a JORC 2012 compliant Mineral Resource of 8.03 Mlb at 382 ppm U3O8 (200 ppm U3O8 cut-off grade).
-
Located only 25 km from Elevate Uranium’s Minerva uranium project.
-
The resource is situated within a broad envelope of anomalism defined by wide spaced, historical drilling offering opportunity for possible resource extensions.
-
Ore samples from Napperby have previously been tested by Elevate Uranium, confirming application of U-pgrade[TM] to add value.
-
Fitton Uranium project (SA) is an early-stage project featuring excellent drill results including:
-
21 m @ 384 ppm U3O8 from 40 m, including 6 m @ 978 ppm U3O8 from 54 m
-
19 m @ 487ppm U3O8 from 79 m, including 6 m @ 1,112 ppm U3O8 from 89 m
-
Another four tenements in the NT and SA are included in the acquisition; these tenements are also prospective for uranium mineralisation.
Elevate Uranium Ltd (ASX: EL8) (OTCQX: ELVUF) (“Elevate Uranium” or “the Company”) is pleased to announce that it has finalised the acquisition of 100% of the issued capital of Uranium Generation Pty Ltd, previously a subsidiary of Core Lithium Ltd (“Core”). The acquisition secures a portfolio of uranium assets in the Northern Territory and South Australia that are complementary to the Company’s existing central Australian holdings.

strategy of consolidating uranium projects in proven regions where its proprietary U-pgrade™ beneficiation process can unlock significant value.
Beyond the Napperby Resource, the acquisition brings high-grade exploration potential through the Fitton Uranium Project in South Australia and the Entia Uranium Project in the Northern Territory, as well as additional tenements in both regions. The Company is of the opinion these are high value underexplored assets, offering significant upside potential through exploration.
The location of all the acquired assets relative to Elevate Uranium’s other uranium assets is shown in Figure 5.
Elevate Uranium Managing Director, Murray Hill, commented:
“This is a logical and highly value-accretive acquisition. Napperby fits seamlessly into our Central Australian portfolio, sitting just 25 km from our Minerva Project. By applying our U-pgrade™ process we strongly believe that we can produce a low-mass high-grade concentrate from Napperby’s shallow, calcrete-hosted mineralisation and add significant value – just as we are doing with our Nambian assets.
In addition to Napperby’s JORC 2012 compliant Mineral Resource of 8.03 Mlb at 382 ppm U3O8, the acquisition includes the highly prospective Entia (NT) and Fitton (SA) uranium projects, that are in the right address for uranium mineralisation and have not had any systematic exploration.
With active support for uranium development in both the NT and SA, this acquisition cements our position as a leading ASX-listed uranium developer with a diversified global portfolio of 169 Mlb U3O8.”
Napperby Uranium Project
Cornerstone to the acquisition is the Napperby uranium project, located approximately 150 km northwest of Alice Springs, along the sealed Tanami Road. Strategically, the project lies just 25 km from Elevate Uranium’s existing Minerva Project (Figure 1), creating a consolidated hub in a region known for its uranium potential.
The Napperby project hosts a JORC 2012 Inferred Mineral Resource, estimated by SRK Consulting to be 9.54 Mt @ 382 ppm U3O8 containing 8.03 Mlb U3O8 (at 200 ppm cut-off). Uranium mineralisation is present in the form of carnotite, occurring in semi-consolidated sandy clays, and to a lesser degree calcrete, hosted within a Tertiary palaeochannel. The current mineralisation model assumes that uranium has been released from basement source rocks due to the presence of acidic-oxidised surface water and transported in solution until precipitated along with carbonate and silica within the palaeochannel system.
The Mineral Resource has a strike length of ~4 km with mineralisation shallow, typically within 3 to 8 m of the surface. It occurs within a ~20 km long mineralised envelope delineated by historical broad spaced drilling (Figure 2). Much of the drilling throughout this mineralised zone is insufficient to allow the estimation of a mineral resource, offering opportunity for possible resource additions from any future infill drill program.
A key driver of this transaction is the technical synergy with Elevate Uranium’s proprietary beneficiation process. In 2013, the Company completed extensive mineralogical analysis and some bench-scale metallurgical test work on samples obtained from the Napperby resource area. The results strongly indicated that the Napperby samples were amenable to the Company’s proprietary U-pgrade[TM] process and application of U-pgrade[TM] could add significant value to Napperby.

The Company has also developed advanced exploration techniques from its extensive exploration programs on its projects in Namibia, which have a similar mineralisation style to Napperby, and believes this expertise can assist in adding to the existing resource.

Fitton Uranium Project
The Fitton project is located in the Flinders Ranges of South Australia ~500 km north of Adelaide in a proven uranium province, within 25 km of the Beverley Uranium Mine and the Four Mile Uranium Mine (Figure 3). Drilling at Fitton by Core in 2013 returned thick, high grade uranium intersections (Figure 4):
-
21 m @ 384 ppm U3O8 from 40 m including 6 m @ 978 ppm U3O8 from 54 m (SLRC017)
-
19 m @ 487 ppm U3O8 from 79 m including 6 m @ 1,112 ppm U3O8 from 89 m (SLRC022)
-
60 m @ 482 ppm U3O8 from 53 m including 4 m @ 3,100 ppm U3O8 from 55 m (SLRC028)
Note drill hole SLRC028 does not represent true thickness, it was drilled to investigate consistency of grade and to test the schist at depth.
The project displays favourable geology with fractures in host granites that have been intruded by a mafic dyke, providing a focus for shearing and concentration of uranium mineralisation. The structure has been traced over 1 km in strike, with potential repetitions of the mineralised structure representing further exploration targets. The greater project area lacks systematic exploration, with targets outside of existing drilling yet to be tested.

Entia is approximately 140 km northeast of Alice Springs (Figure 1). The project displays favourable geology and regional structures, offering a variety of possible target types, with potential for both metasomatism related and pegmatite associated mineralisation. Exploration however is at an early stage requiring integration and assessment of historic datasets.

About Elevate Uranium
Elevate Uranium Ltd (ASX:EL8, OTCQX:ELVUF, NSX:EL8) is a uranium exploration and development company focused on unlocking the value of its globally significant resource base through its proprietary, 100%-owned U-pgrade[TM] beneficiation process.
The Company holds a substantial Mineral Resource portfolio totalling 169 Mlb U3O8 across its projects in Namibia and Australia. Its flagship Namibian portfolio is located in the established, world-class Erongo uranium province and includes the Koppies Uranium Project (JORC 2012: 66.1 Mlb U3O8) and the Marenica Uranium Project (JORC 2012: 46 Mlb U3O8 – Elevate Uranium’s share).
In Australia, Elevate Uranium has tenements and joint venture interests containing substantial uranium resources. The Angela, Napperby, Thatcher Soak and Minerva project areas; and joint venture holdings in the Bigrlyi, Malawiri, Walbiri and Areva joint ventures, in total contain 57 Mlb of high-grade uranium mineral resources.

==> picture [500 x 58] intentionally omitted <==
==> picture [500 x 115] intentionally omitted <==
The U-pgrade™ Strategic Advantage
U-pgrade[TM] is the Company’s patented beneficiation process, which provides a clear pathway to unlock its large-scale, surficial, secondary uranium deposits.
The process is designed to be economically transformational with bench-scale testwork on Marenica Project samples demonstrating the potential of U-pgrade[TM] to :
-
Concentrate the uranium by a factor of ~50, increasing the grade of ore from ~93 ppm U3O8 to ~ 5,000 ppm U3O8.
-
Rejects ~98% of gangue (waster material from the mass prior to leaching).
-
Removes acid-consuming minerals.
-
Reduces potential CAPEX and OPEX by ~50% compared to conventional processing.
Beyond application at the Marenica Uranium Project, Elevate Uranium has determined, through bench scale testing, that secondary uranium deposits in Namibia and Australia are amongst those that are amenable to the U-pgrade[TM] process.
Note: Please refer to ASX announcement dated 18 April 2017 titled “Scoping Study Completed – Marenica Project Highly Competitive with Industry Peers” and ASX announcement dated 4 April 2025 titled “Clarification of U-pgrade™ Ore Samples JORC Compliance” for further details on the factors referred to above.

subsequent samples. This is tempered by
the sample size being so large that these
effects are negligible.
Recovery for sonic drilling was excellent
and was maximised by managing drilling
rate of penetration and hydrostatic load to
prevent loss of sample from drill bit
annulus. Samples were immediately placed
in plastic sleeves to prevent loss of fines
and moisture.
Contamination in sonic drilling only
occurred in the top few metres, above the
mineralisation, and was easily removed
from the sample tubes. Casing was
introduced to minimise this.
Auger samples were piled onto geotextile
mats, where the sample volume could be
assessed and bottom of the hole
measured. The mat contents were then
dried, weighed and split using a large riffle
splitter with vibrating solenoids.

| Sub- sampling techniques and sample preparation If core, whether cut or sawn and whether quarter, half or all core taken. If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. For all sample types, the nature, quality and appropriateness of the sample preparation technique. Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling. Whether sample sizes are appropriate to the grain size of the material being sampled. Auger and sonic core sub-sampling methods described above. Toro sample preparation techniques (screening and splitting) appear adequate, as demonstrated by duplicate regime and twins of auger-sonic and sonic-sonic. Toro instituted a regime of field duplicates, preparation of duplicates and analytical duplicates, beyond the laboratory’s QA/QC regime. All data was assessed regularly for uniformity. Umpire assays were also regularly obtained from independent laboratories. No significant sampling issues were identified. Sample sizes, particularly the auger ones, are much larger than in typical exploration programs and therefore adequate for the nuggetty mineralisation that characterises Napperby and other calcrete-style uranium deposits. |
|
| Quality of assay data and laboratory tests The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibration factors applied and their derivation, etc. Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established. QA/QC program included field/ laboratory duplicates and matrix-matched standards. QA/QC performance has been documented and indicates good agreeance. Assay method routinely used is XRF pressed pellet, which is routine for this style of mineralisation and best matches the NAA method, which is considered definitive (but too costly and slow to roll out). Toro undertook considerable test-work and umpire analyses using different methods at different laboratories, all indicating this was the most appropriate assay method. High levels of Strontium in some samples were found to affect XRF spectra for Uranium, but not sufficient in quantum or spatial extent to warrant an alternate assay technique. PFN tool was used in 18 holes to compare to gamma and assay measurements. Reputable laboratory (ALS) used for routine assaying. |

| Verification of sampling and assaying The verification of significant intersections by either independent or alternative company personnel. The use of twinned holes. Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. Discuss any adjustment to assay data. Toro twinned five high-grade Deep Yellow holes, and the results suggested that the Deep Yellow NP (auger) holes were biased high, but this might partially be a result of the ‘return to the mean’ statistical phenomenon. Follow-up twinning of 11 holes with more representative grades around the mean grade showed very little differences. Toro twinned a sufficient number of its own sonic and auger holes to provide a reliable understanding of small-scale variability. Umpire samples showed excellent agreeance with the original data. Data was largely digitally entered into Tablets; data was verified and uploaded into DataShed. No adjustments to the assay data have been carried out. |

| Location of data points Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. Specification of the grid system used. Quality and adequacy of topographic control. All drill hole collars collected by DGPS. During 2016 and 2007, data was collected by BB Surveys from Alice Springs, who established a base station. In 2008, Toro purchased a post-processed DGPS unit (Magellan) and collected collars from that point forward. During the Toro DGPS survey, checks of 2006 Deep Yellow and 2007 Toro collars showed there were errors in elevation (RL) at a decimetre scale and these were rectified by BB Surveys. GDA94 Zone 53. |
|
| Data spacing and distribution Data spacing for reporting of Exploration Results. Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. Whether sample compositing has been applied. Drilling is mostly 100 × 100 m, which is insufficient to define continuity of the mineralisation at a local level. Approximately 100 Toro holes were drilled at 50 × 50 m spacing (including a line at 25 m spacing). Central zone of the orebody was drilled at 50 × 50 m (Deep Yellow) with one drilling line drilled at 25 m spacing. Samples were composited to 1 m. Deep Yellow auger samples are 1 m long, while Toro sonic and auger samples are 0.5 m long. |

| Exploration done by other parties Acknowledgment and appraisal of exploration by other parties. All modern exploration to date was carried out by Deep Yellow and Toro (2005– 2009). Prior to 2005, exploration was carried out by Paladin Energy Ltd (“Paladin”) and Uranerz. All exploration was focused on uranium mineralisation. The Napperby (New Well) deposit was first discovered and explored by CRA Exploration and Uranerz in the late 1970s and early 1980s. They drilled wide- spaced auger and aircore holes and defined a ‘mineralised area’ but did not publish a mineral resource. The deposit remained dormant for over a decade until Paladin applied for the ground in the early 2000s. Deep Yellow subsequently acquired the Project from Paladin in 2005, then after undertaking drilling, secured an option to purchase with Toro Energy Ltd. In 2007, Toro Energy drilled 515 sonic core holes, 123 auger holes and 814 aircore holes, followed in 2008 by a further 333 sonic core holes and 784 aircore holes. Following that work, in 2009, Toro Energy expanded the historic Napperby resource by 400% to a JORC Code Inferred Mineral Resource of 9.34 Mt at 359 ppm (0.036%) U3O8 for 3351 t (7.39 Mlb) of contained uranium oxide using a 200 ppm U3O8 cut-off (Toro Energy, ASX release on 03/03/2009). Only 50% of the known mineralised area was included in the 2009 Mineral Resource. This option to purchase was not eventually executed following Scoping Studies that concluded the Project was uneconomic at the current scale/ grade. In 2010, the Project fell 100% back into the hands of Deep Yellow. No further exploration took place. The Napperby deposit and a small part of the original EL24246 was relinquished in October 2016. Elevate Uranium inherited a database that includes 2,308 auger, sonic core and aircore drillholes from Toro/Deep Yellow, downhole gamma and assay data, PFN and disequilibrium data, metallurgical test- |

| work, scoping study, airborne electromagnetics and high-resolution magnetics/ radiometrics, gravity, and baseline groundwater environmental monitoring data. Core digitised the 820 Uranerz drillholes, including assay and gamma data. Toro undertook metallurgical test-work from bulk representative samples derived from Napperby in 2008 and 2009, aimed at characterising the ore and gangue, determining how suitable the mineralisation is for beneficiation and the optimal conditions for leaching. Tests included comminution, scrubbing and column leach trials (Toro Energy, ASX release on 09/06/2009). Toro proceeded to a Scoping and Conceptual Study conducted by URS Australia, which examined various conventional mining and processing options available at the time, such as heap leach, agitated leach, direct precipitation and resin-in-pulp. Alternative mining cut-off grades and the potential for nearby deposits were also considered, as was initial up-front beneficiation. A high-level review of infrastructure requirements, environmental management and CAPEX and OPEX scenarios was also undertaken. |
|
| Geology Deposit type, geological setting and style of mineralisation. The Napperby Project (historically known as the New Well deposit) comprises an extensive, consistently mineralised zone within 2–10 m of the surface in semi- consolidated and unconsolidated sediments within a Tertiary paleochannel over a 20 km length (striking NNE) in the Arunta Region in the Northern Territory. Carnotite mineralisation resides mostly in sands and sandy clays as finely disseminated particles and blobs up to 5 cm long, but can also be found in overlying calcrete as joint coatings. The current geological model has it that uranium is released from basement rocks into the aquifer system due to the presence of acidic-oxidised surface waters. Uranium is carried in solutions |
