Announcement PDF Alligator Energy Limited Level 1, 5-7 King William Road Unley SA 5061 ASX Announcement 7 October 2026 Alligator Energy Ltd (ASX: AGE, Alligator or the Company) is delighted to announce further drilling results from the southern extension of the Blackbush deposit at its Samphire Uranium Project. Recent drilling has extended the interpreted mineralised trend by approximately 1 km, with mineralisation remaining open at both ends of the newly tested trend. Highlights • New uranium mineralisation above a 250ppm eU₃O₈ cut-off has been intersected approximately 1 km south of the previously southernmost known mineralised drill hole at Blackbush, extending the known mineralised footprint along the Blackbush- Plumbush corridor (Figure 1). • Two adjacent drill holes, spaced approximately 100 metres apart, both returned significant mineralised intersections above cut-off1 : - BBRM26-590: 5.2 m at 0.15% (1,498ppm) eU3O8 from 64.7 m (GT 7,820m.ppm) - BBRM26-592: 6.6 m at 0.12% (1,245ppm) eU3O8 from 62.7 m (GT 8,214m.ppm) • Drilling within this previously untested section of the Blackbush-Plumbush corridor has confirmed the continuation of the channel, significantly expanding the prospective area for broader uranium mineralisation between the two deposits. • More than 9,000 metres of drilling across 91 holes has been completed to date under the Samphire Growth Strategy since the Company’s previous drilling update2 , with drilling continuing across priority targets in the Blackbush-Plumbush corridor and Plumbush. Alligator’s CEO and Managing Director Andrea Marsland-Smith stated: Every hole in our Samphire Growth Strategy helps answer the question that matters most for an in-situ recovery project: how large an area of the channel is mineralised above cut-off. South of Blackbush, holes BBRM26-590 and BBRM26-592 intersected mineralisation above cut-off a kilometre beyond our previous drilling. This is an exciting step-out and provides further evidence of the potential scale of the mineralised system south of Blackbush. 1 All widths are downhole widths. Equivalent uranium grades (eU₃O₈) are derived from calibrated downhole natural gamma logging and are not chemical assays. Refer to Appendix 1 for all material drill-hole information and to the JORC Table 1 disclosure for the reporting criteria. 2 ASX Release: Drilling Extends Uranium Mineralisation South of Blackbush, 28 July 2026 https://alligatorenergy.com.au/announcements/7653188 DRILLING PROVIDES SUBSTANTIAL AREA EXTENSION TO MINERALISATION AT SAMPHIRE 2 Alligator Energy Limited Level 1, 5-7 King William Road Unley SA 5061 At Plumbush, the first modern drilling undertaken by Alligator is also delivering results consistent with the historical drilling that underpins the existing Inferred Mineral Resource. Together, these results continue to build our understanding of the broader Samphire mineralised system and reinforce the rationale behind our Growth Strategy. Samphire Growth Strategy The circa 300-hole Growth Strategy program announced in early July 20263 was designed to test the southern extension of Blackbush4 , increase drill density at Plumbush5 and investigate the underexplored corridor between the two deposits. Access to these key areas was secured through the Option to acquire the Mullaquana Crown Lease. The program is just over one third completed with the following being completed since the last Samphire drilling update released on 28 July 2026: • Thirty-eight (38) rotary mud holes within the Blackbush extension and the wider Blackbush-Plumbush corridor • Fifty (50) rotary mud infill holes within the Plumbush deposit Mineral Resource extent, and • Three (3) sonic core holes which recovered physical samples for assay to support downhole geophysics and geological interpretation. 3 ASX Release: Samphire extensional drilling commences, 8 July 2026, https://alligatorenergy.com.au/announcements/7622554 4 ASX Release: Increased Mineral Resource Estimate - Blackbush Deposit, 6 May 2025, https://alligatorenergy.com.au/announcements/6942606 5 ASX Release: Samphire Mineral Resource Grows 67%, 19 June 2026, https://alligatorenergy.com.au/announcements/7591585 3 Alligator Energy Limited Level 1, 5-7 King William Road Unley SA 5061 Figure 1: Recent drilling in the southern extension of Blackbush and Plumbush. 4 Alligator Energy Limited Level 1, 5-7 King William Road Unley SA 5061 Blackbush Extension and Corridor Alligator’s 28 July 2026 ASX announcement reported uranium mineralisation extending approximately 600 m south of earlier drilling following access to the Mullaquana Crown Lease6 . The latest results build on that work, extending the interpreted mineralised trend into additional ground south of Blackbush (Figure 1). The distribution of mineralised intersections is interpreted to indicate a southerly continuation of the Blackbush mineralised trend. Follow-up drilling is required to determine continuity between the intersections and to define the limits of mineralisation. Significant intercepts include: • BBRM26-575: 1.0 m at 0.13% (1,347ppm) eU3O8 from 51.2 m (GT 1,374m.ppm) • BBRM26-580: 3.2 m at 0.13% (1,286ppm) eU3O8 from 61.0 m (GT 4,102m.ppm) • BBRM26-587: 2.2 m at 0.23% (2,277ppm) eU3O8 from 57.1 m (GT 4,964m.ppm) • BBRM26-590: 5.2 m at 0.15% (1,498ppm) eU3O8 from 64.7 m (GT 7,820m.ppm) • BBRM26-592: 6.6 m at 0.12% (1,245ppm) eU3O8 from 62.7 m (GT 8,214m.ppm) Plumbush Infill Drilling The commencement of the Samphire Growth Strategy marked the start of infill drilling at Plumbush, located approximately 5 km south of Blackbush. The program aims to progressively reduce historical drill spacing from approximately 200 m x 400 m to 100 m x 100 m, increasing confidence in the resource with the aim of converting the Inferred Mineral Resource to the Indicated category. Further drilling to reduce spacing to between 25 m x 25 m and 50 m x 50 m in the most prospective areas is planned for future programs. Drilling within the Plumbush deposit has returned results consistent with the recent Inferred Mineral Resource Estimate, which was generated exclusively from historic data.7 The inclusion of more modern geophysical tools has further delineated the structure of the primary palaeochannel including coarser basal sands similar to those hosting higher grade mineralisation within the Blackbush deposit. Significant intercepts include: • BBRM26-534: 2.4 m at 0.44% (4,370ppm) eU3O8 from 64.6 m (GT 10,662m.ppm) • BBRM26-519: 2.3 m at 0.15% (1,479ppm) eU3O8 from 67.8 m (GT 3,387m.ppm) • BBRM26-546: 1.3 m at 0.10% (1,036ppm) eU3O8 from 59.3 m (GT 1,389m.ppm) • BBRM26-565: 6.5 m at 0.11% (1,091ppm) eU3O8 from 66.7 m (GT 7,100m.ppm) • BBRM26-501: 1.6 m at 0.07% (727ppm) eU3O8 from 62.5 m (GT 1,193m.ppm) • BBS26-0168 : 3.4 m at 0.07% (711ppm) eU3O8 from 62.5 m (GT 2,396m.ppm) • BBS26-015: 1.2 m at 0.13% (1,321ppm) eU3O8 from 64.3 m (GT 1,585m.ppm) 6 ASX Release: Option Agreement Secures Crown Lease, 19 June 2026, https://alligatorenergy.com.au/announcements/7591587 7 ASX Release: Samphire Mineral Resource Grows 67%, 19 June 2026, https://alligatorenergy.com.au/announcements/7591585 8 BBS26-015 and BBS26-016 are sonic holes drilled by Star Drilling.

William Road Unley SA 5061 JORC Code, 2012 Edition – Table 1 Sections 1 and 2 Section 1 – Sampling Techniques and Data Criteria JORC Code explanation Commentary Sampling techniques • Nature and quality of sampling (eg 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 (eg ‘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 (eg submarine nodules) may warrant disclosure of detailed information. • The work is based on rotary mud and sonic drilling and all grade determinations are from downhole geophysical logging. Sondes were appropriately calibrated. • Downhole wireline logging used a natural gamma sonde. • The sonde was calibrated at the Australian Mineral Development Laboratories (AMDEL) calibration facility (Adelaide) to allow calculation of uranium grade (eU3O8) from logged natural gamma. Drilling techniques • Drill type (eg core, reverse circulation, open- hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg 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). • BBRM Prefixed Holes were drilled using the rotary mud drilling technique. All holes were drilled vertically. • BBS Prefixed holes were drilled using the Sonic Drilling method. 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. • Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. • Conventional drill sample recovery is not applicable. Grade is derived from downhole natural gamma logging rather than from physical sample recovery. • Core Samples from Sonic Holes will be assayed with results released following QAQC. Logging • Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. • Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. • The total length and percentage of the relevant intersections logged. • Chip/mud samples were collected every 1 m in the zones of interest for geological logging. • Drilled intervals were photographed from chip trays using a high-resolution camera. 13 Alligator Energy Limited Level 1, 5-7 King William Road Unley SA 5061 Criteria JORC Code explanation Commentary 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. • No physical sub-sampling has been performed as grade determination is by downhole natural gamma sonde measurement, with raw counts-per-second data aggregated to 0.1 m intervals using a median moving-window filter prior to estimation. • QAQC on all eU3O8 data was performed on a hole-by-hole basis to confirm data integrity. • eU3O8 data were aggregated downhole from raw LAS files into 0.1 m wide intervals using a median moving window filter. 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, calibrations 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. • Geophysical logging was carried out by Borehole Wireline. All holes were logged using a natural gamma tool and equivalent uranium grades expressed as percentage eU₃O₈ are assigned to each 0.1 m logged interval. 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. • No independent assay verification has been performed on these holes. 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. • Drillholes are sited using a Garmin handheld GPS. • Drilled holes are surveyed using a Leica iCON GPS 60 which uses the 4G network to obtain corrections from SmartNet base stations (Continuously Operating Reference Stations (CORS)) located around Whyalla. The SmartNet corrections result in RTK RMS accuracy of 10-20mm in XY and 20-30mm in Z. • Grid system GDA94 Projection 53H 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 • Drill spacing varies from 50 m x 50 m to 100 m x 100 m centres. 14 Alligator Energy Limited Level 1, 5-7 King William Road Unley SA 5061 Criteria JORC Code explanation Commentary applied. • Whether sample compositing has been applied. Orientation of data in relation to geological structure • Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. • If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. • The Samphire mineralisation is interpreted to be contained in horizontal to sub-horizontal sequence of sediments and underlying weathered granite. This interpretation is derived from the significant historical drilling and geological interpretation of the area. • All drillholes are vertical which is appropriate for the orientation of the mineralisation Sample security • The meas
