Announcement PDF Level 9, 2 Mill Street Perth WA 6000 T 61 8 8317 1700 E info@corelithium.com.au ABN 80 146 287 809 ASX CXO 6 November 2024 ASX: CXO Announcement New high-grade Lithium drill results within 20km of the Grants processing facility Highlights • Excellent new lithium drilling results at the Blackbeard prospect, including: o 63m @ 1.67% Li2O from 166m, including 20m @ 2.09% Li2O from 208m (NRC269) • Builds on strong previously reported Blackbeard results of 41m @ 1.63% Li2O from 137m (SRC117) and 59m @ 1.54% Li2O from 158m (SRC118).1 • Lithium mineralisation now confirmed over 600m of strike when combined with the adjacent Centurion prospect. • The Blackbeard mineralisation is clearly defined and entirely contained within Core Lithium’s 100%-owned Mining Lease. This lease is strategically located within 20km of the Grants processing facility. Core Lithium Ltd (ASX:CXO) (Core or Company) is pleased to provide an update on the exploration drilling program being undertaken at the 100% owned Finniss Lithium Project (Finniss Project). Initial assays have been received from RC (reverse circulation) drilling with wide zones of spodumene mineralisation intersected at the Blackbeard prospect (Figure 1). These results, together with those previously reported for the nearby Centurion prospect, demonstrate mineralised pegmatites exist along a clearly defined strike length within the Company’s existing mining lease. The exploration focus for the 2024 field season at Finniss has been on testing large scale pegmatite targets which can potentially sustain lower cost production. Results are presented here for 27 drill holes that represent 4,880m of drilling across a range of prospects that are all within 20km of the Grants Processing Facility. 1 See ASX announcement “Significant Increase to Finniss Mineral Resources” on 18 April 2023 corelithium.com.au 1 Commenting on the Blackbeard drilling results, Core CEO Paul Brown said: “The results from Blackbeard are highly encouraging and indicate we have discovered a large, highly mineralised pegmatite within a short distance of our processing infrastructure, consistent with the key objective of our 2024 field season. Blackbeard is up to 45 metres wide and open at depth. Further drilling will be completed to determine the ultimate scale of the system. This will support a future Mineral Resource Estimate and have potential to be incorporated into our ongoing restart studies.” Figure 1: Location of Blackbeard prospect and Grants processing facility Blackbeard Excellent results were received from seven drill holes infilling and testing depth extensions at the Blackbeard prospect (Table 1 and Figure 2). Results from the current RC drill program included: • 63m @ 1.67% Li2O from 166m, including 20m @ 2.09% Li2O from 208m (NRC269) • 24m @ 0.70% Li2O from 188m (NRC270) • 22m @ 0.68% Li2O from 135m, including 6m @ 1.25% Li2O from 208m (FRC488) 2 corelithium.com.au Previous intersections at Blackbeard include 41m @ 1.63% Li2O (SRC117) and 59m @ 1.54% Li2O (SRC118)1. Drilling to date has demonstrated that the primary mineralised pegmatite body is steeply dipping within the mining lease, up to 45m in true thickness and remains open at depth (Figure 3). With the largest and highest-grade intersection in NRC269 currently also the deepest. Furthermore, the drilling has identified a smaller subparallel pegmatite body to the north of the main pegmatite (Figure 3) with current indications that it is also mineralised. While many of the drill holes intersected this secondary body, it was often intersected at shallow depths in the weathering zone where lithium is typically depleted. Several holes did intersect fresh pegmatite however, including: • 10m @ 0.91% Li2O from 108m (NRC269) Blackbeard is located directly northeast of the nearby Centurion prospect (Figure 2) where previous drilling resulted in mineralised intersections including 22m @ 0.74% Li2O (CRC001) and 18m @ 0.85% Li2O (FRC391)2. The drill results at the Blackbeard and Centurion prospects (Figure 2) define a mineralised trend with a strike extent of over 600m. This makes Blackbeard-Centurion one of the larger pegmatite trends discovered to date within the Finniss Project area. The two pegmatites appear to be closed off to the northeast and southwest but remain open at depth. They are located entirely within Core’s granted Mining Lease (MLN1148) and this may enable a quicker path to development. A number of other prospects within the immediate vicinity such as Northern Reward, Kristies and Frilled Lizard (Figure 2) also warrant further drill testing and exploration. Regional Results - Drilling First pass drilling at other prospects, including at Kristies, Zola East, Rocky Ridge West and Archer (Table 1) did not intersect any significant lithium mineralisation despite many of these holes intersecting pegmatite. An evaluation of the results will be undertaken to determine if any follow-up drilling is warranted. Next Steps Drilling is continuing at a number of high priority pegmatite targets across the Finniss Project including further drilling of targets adjacent to Blackbeard. All targets are within trucking distance of the Grants processing facility and results are expected next month. Given these excellent results, it is anticipated that further drilling will be undertaken at Blackbeard as soon as practicable after the end of the wet season in early CY25. Drilling would target depth extensions to the mineralisation as well as potentially collecting geotechnical information and samples for preliminary metallurgical test work. If drilling is successful, it would provide the data necessary to include Blackbeard (alongside deposits such as BP33, Carlton and Lees) in any re-start strategy and longer-term mine plan discussions. 2 See ASX announcement “Finniss Lithium Project Exploration Update” on 13 December 2021 3 corelithium.com.au Figure 2: Blackbeard drill plan Figure 3: Blackbeard Cross Section 4 corelithium.com.au This announcement has been approved for release by the Board of Core Lithium Ltd.

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. 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). 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. • • Reverse circulation (RC) drill techniques have been employed for the Core Lithium Ltd (“Core” or “CXO”) drilling. A list of the hole IDs and positions for drilling discussed in the release has been included. RC drill spoils over all programs were collected into two sub-samples: -1 metre split sample, homogenized and cone split at the cyclone into 12x18 inch calico bags. Weighing 2-5 kg, or 15% of the original sample. -20-40 kg primary sample, which for CXO’s drilling was collected in 600x900mm green plastic bags and retained until assays had been returned and deemed reliable for reporting purposes. RC sampling of pegmatite for CXO’s assays was done on a 1 metre basis. 1m sampling continued into the barren wall-zone adjacent to the pegmatite. • RC Drilling was carried out with 5 inch face-sampling bit. • RC drill recoveries were visually estimated from volume of sample recovered. The majority of sample recoveries reported were above 90% of expected. RC samples were visually checked for recovery, moisture and contamination and notes made in the logs. The rigs splitter was emptied between 1m samples. A gate mechanism on the cyclone was used to prevent inter-mingling between metre intervals. The cyclone and splitter were also regularly cleaned by opening the doors, visually checking, and if build-up of material was noted, the equipment cleaned with either compressed air or high-pressure water. Drill collars are sealed to prevent sample loss and holes are normally drilled dry to prevent poor recoveries and contamination caused by water ingress. Wet intervals are noted in case of unusual results. • • • 7 corelithium.com.au Criteria JORC Code Explanation Commentary • Logging • • • Sub-sampling techniques and sample preparation • • • • • • Quality of assay data and laboratory tests • • • Verification of sampling and assaying • • • 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.

Detailed geological logging was carried out on all RC drill holes. Logging recorded lithology, mineralogy, mineralisation, weathering, colour, and other sample features. RC chips are stored in plastic RC chip trays. All holes were logged in full. Pegmatite sections are also checked under a single-beam UV light for spodumene identification on an ad hoc basis. These only provide indicative qualitative information. RC chip trays are photographed and stored on the CXO server. The majority of the mineralised samples were collected dry, as noted in the drill logs and database. RC samples were collected from the cone splitter on the drill rig into a calico bag for dispatch to the laboratory. The sample sizes are considered more than adequate to ensure that there are no particle size effects relating to the grain size of the mineralisation. A field duplicate sample regime is used to monitor sampling methodology and homogeneity of RC drilling. The typical procedure was to collect duplicates via a split directly from the cone splitter. Sample prep for drilling occurs at Intertek Laboratories, Darwin, NT. RC samples do not require any crushing, as they are largely pulp already. RC Samples are then split and prepared by pulverising to 95% passing 100 um. Field and lab standards together with blanks were used routinely. For drilling, lithium sample analysis occurs at Intertek, Darwin, NT. All samples are crushed and pulverized. For lithium samples, a sub-sample of the pulp is digested via a sodium peroxide fusion in a Ni crucible and analysed via ICP-MS and ICP-OES methods for the following elements: Li, Al, B, Ba, Be, Ca, Cs, Fe, K, Mg, Mn, Nb, P, Rb, S, Sn, Sr, Ta, W and As. Intertek utilise standard internal quality control measures including the use of Certified Lithium Standards and duplicates/repeats. CXO implemented quality control procedures include appropriate certified Lithium ore standards, duplicates for RC drilling and blanks. There were no significant issues identified with any of the QAQC data. Senior technical personnel have visually inspected and verified the significant drill intersections. All field data is entered into specialised Ocris logging software (supported by look-up tables) at site and subsequently validated as it is imported into the centralized CXO Access database. 8 corelithium.com.au Criteria JORC Code Explanation Commentary • • Discuss any adjustment to assay data. • 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.

Metallic Lithium percent was multiplied by a conversion factor of 2.1527/10000 to report Li ppm as Li2O%. Differential GPS has been used to determine the majority of collar locations, including RL. Some of the 2024 drilling remains to be surveyed and hand-held GPS coordinates were used. Collar position audits are undertaken, and no issues have arisen. The grid system is MGA_GDA94, zone 52 for easting, northing and RL. All RC hole traces were surveyed by north seeking gyro tool operated by the drillers. The local topographic surface is used to generate the RL of collars when coordinates are obtained via handheld GPS. The lithium mineralisation and geology show good continuity from hole to hole at the more heavily drilled prospects and will be sufficient to support the definition of a Mineral Resource and the classifications contained in the JORC Code (2012 Edition). Most mineralised intervals reported are based on a one metre sample interval. Drilling traverses were planned to be oriented approximately perpendicular to the interpreted strike of mineralization (pegmatite body) as mapped. Because of the dip of the hole, drill intersections are apparent thickness and overall geological context is needed to estimate true thickness. Estimates of true thickness are between 50-90%. No sampling bias is believed to have been introduced. Sample security was managed by the CXO. After preparation in the field or CXO’s warehouse, samples were packed into polyweave bags and transported by a freight transport company directly to the assay laboratory. The assay laboratory audits the samples on arrival and reports any discrepancies back to the Company. No such discrepancies occurred. No audits or reviews of the techniques or data associated with the drilling reported have occurred. 9 corelithium.com.au Section 2 Reporting of Exploration Results (Criteria listed in the preceding section also apply to this section.)

There are no registered native title interests covering the areas being drilled. Across the tenure there are known Aboriginal sacred sites as well as archaeological and heritage sites. Disturbance of these are avoided. The tenements are in good standing with the NT DIPR Titles Division. The areas being drilled comprises predominantly Vacant Crown land and to a lesser extent Crown Leases (perpetual and term) as well as minor Freehold private land. The history of mining in the Bynoe area dates back to 1886 when tin was discovered by Mr. C Clark. By 1890 the Leviathan Mine and the Annie Mine were discovered and worked discontinuously until 1902. In 1903 the Hang Gong Wheel of Fortune was found, and 109 tons of tin concentrates were produced in 1905. In 1906, the mine produced 80 tons of concentrates. By 1909 activity was limited to Leviathan and Bells Mona mines in the area with little activity in the period 1907 to 1909. The records of production for many mines are not complete, and in numerous cases changes have been made to the names of the mines and prospects which tend to confuse the records still further. In many cases the published names of mines cannot be linked to field occurrences. In the early 1980s the Bynoe Pegmatite field was reactivated during a period of high tantalum prices by Greenbushes Tin which owned and operated the Greenbushes Tin and Tantalite (and later spodumene) Mine in WA. Greenbushes Tin Ltd entered into a JV named the Bynoe Joint Venture with Barbara Mining Corporation, a subsidiary of Bayer AG of Germany. Greenex (the exploration arm of Greenbushes Tin Ltd) explored the Bynoe pegmatite field between 1980 and 1990 and produced tin and tantalite from its Observation Hill Treatment Plant between 1986 and 1988. They then tributed the project out to a company named Fieldcorp Pty Ltd who operated it between 1991 and 1995. In 1996, Julia Corp drilled RC holes into representative pegmatites in the field, but like all their predecessors, did not assay for Li. Since 1996 the field has been defunct until recently when exploration has begun ascertaining the lithium prospectivity of the Bynoe pegmatites. The NT geological Survey undertook a regional appraisal of the field, which was published in 2004 (NTGS Report 16, Frater 2004). 10 corelithium.com.au Criteria JORC Code explanation Commentary • • • Geology • Deposit type, geological setting and style of mineralisation. • • • Drill hole Information • • Data aggregation methods • • A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: o easting and northing of the drill hole collar o elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar o dip and azimuth of the hole o down hole length and interception depth o hole length. If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually Material and should be stated.

The operators at that time were seeking Tin and Tantalum. CXO subsequently drilled BP33, Grants, Far West, Central, Ah Hoy and several other prospects in 2016. After purchase of the Liontown tenements in 2017, CXO drilled Lees, Booths, Carlton and Hang Gong. The CXO tenure covers a complex zoned rare element pegmatite field, which comprises the 55km long by 10km wide West Arm – Mt Finniss pegmatite belt (Bynoe Pegmatite Field; NTGS Report 16). The Finniss pegmatites have intruded early Proterozoic shales, siltstones and schists of the Burrell Creek Formation which lies on the northwest margin of the Pine Creek Geosyncline. To the south and west are the granitoid plutons and pegmatitic granite stocks of the Litchfield Complex. The source of the fluids that have formed the intruding pegmatites is generally accepted as being the Two Sisters Granite to the west of the belt, and which probably underlies the entire area at depths of 5-10 km. Lithium mineralisation has been identified historically as occurring at Bilatos (Picketts) and Saffums 1 but more recently LTR and CXO have identified spodumene at numerous other prospects, including Grants, BP33, Booths, Lees, Hang Gong, Ah Hoy, Far West Central and Sandras. A summary of material information for all drill holes discussed in this release is contained within the body of the report. This includes all collar locations, hole depths, dip and azimuth as well as current assay or intercept information. Only drill holes with assays returned are discussed and presented here. Any sample compositing reported here is calculated via length weighted averages of the 1 m assays. Length weighted averages are acceptable method because the density of the rock (pegmatite) is constant. 0.3% Li2O was used as lower cut off grades for compositing and reporting intersections with allowance for including up to 3m of consecutive drill material of below cut-off grade (internal dilution).
