This recent batch of assays mainly from Stage 2 drilling provide encouraging results for the development of the gold at the Mt Ida Project. These intercepts illustrate further continuity of mineralisation which remains open in all directions and can be seen in Figure 1. 1 Refer ASX Announcement 26 Sep2024 titled “Delta commences Strategic Review of Mt Ida Gold Assets” 2 Refer ASX Announcement 14 November 2024 titled “Activities Update from Mt Ida Gold Project” 3 Refer ASX Announcement 28 June 2024 titled “Mt Ida Gold MRE Update” ASX ANNOUNCEMENT 24 January 2025 In addition, the Company has concluded a Strategic Review of Mt Ida gold project and on the basis of the Review results, and the ongoing exploration results that are the subject of this Announcement and results from the previous Quarter2, have decided to continue with the gold Project’s development. Commenting on the strategy Managing Director, James Croser said; “Mt Ida continues to deliver excellent gold results and good likelihood of an expanded gold resource. As part of the strategic review, we explored various opportunities for the Project and currently the best outcome for Delta shareholders suggests we continue with the growth and development work. The gold market is maintaining very positive momentum and all of our options remain open. Mt Ida remains a very valuable and attractive project, hosting both sizeable gold and lithium resources, which we are confident will deliver significant shareholder value. Delta remains in a strong financial position to pursue development outcomes for both its lithium and gold assets.” Mt Ida Exploration Update Mt Ida is located approximately 240km north of Kalgoorlie in Western Australia. The Project area resides on granted mining leases and is fully permitted for commencement of open pit and underground mining at Baldock on mining leases outlined on Figure 3. One reverse circulation (RC) rig and one Diamond Drill (DD) rig are currently operating at the project, focused on resource extensions and resource growth with to the aim of growing the current Mineral Resource Estimate (MRE) of 752,000oz 2@3.5g/t 3 gold. The Company’s current drill program will continue to focus on gold resource growth. A favourable gold price environment, and the results of the recent Strategic Review indicate the most favourable pathway to maximising value from the Mt Ida gold asset is to continue to grow the gold resource to a standalone scale. Delta is aiming to achieve growth via the current 4-Stage extensional drill program which continues to intercept mineralisation well beyond the current MRE. 2 Refer ASX Announcement 14 November 2024 titled “Activities Update from Mt Ida Gold Project” 3 Refer ASX Announcement 28 June 2024 titled “Mt Ida Gold MRE Update” 2 ASX ANNOUNCEMENT 24 January 2025 Figure 1: Long Section of Baldock lode indicating new significant intercepts. This recent batch of drill results from Stage 2 has demonstrated increasing grades and thickness at depth within Baldock North. For example, see Figure 2 position of the high-grade intercept in IDRD364 extending the Meteor 140 domain ~30m beyond the current block model and 75m down-dip of Delta’s optimised mining shapes. Intercepts included in this announcement extend known lodes along strike and down dip (see Figure 3 long section). Further follow up drilling will be completed in the current program, to extend these high-grade intercepts, including around IDRD364.

As part of Delta’s first gold focused program at Mt Ida, the Stage 4 drilling is testing a number of high priority regional targets across the tenement package, including at Bombay, West Nell, Jupiter, Saturn and Unexpected prospects. The first two holes have been returned from the maiden Bombay RC program which included intercepts of shallow mineralisation, such as 14m @ 1.3g/t from 38m in BYRD006. This program will aim to extend known mineralisation, twin and verify historic intercepts via a robust QAQC system with the intention of including Bombay in the next MRE update. The Company looks forward to updating the market as more results become available. 5 ASX ANNOUNCEMENT 24 January 2025 Figure 4: Plan showing the potential Baldock mining hub, surrounding JORC Resources and currently planned regional drilling Strategic Review In September 2024 Delta appointed Bell Potter Securities as financial advisor to conduct a formal strategic review of the gold opportunity at Mt Ida and determine how best to monetise the asset. The decision was in line with Delta’s stated strategy to maintain a principal focus on its lithium assets contained at Mt Ida and the Yinnetharra Project in the Gascoyne region. The Strategic Review has now been completed and the results indicated that the most value accretive development pathway is for Delta to continue advancing the Project towards genuine standalone scale. In terms of tidying the corporate structure of Delta’s business, the Company has placed the Mt Ida gold assets into Mt Ida AU Pty Ltd, a wholly-owned subsidiary of Delta Lithium which was incorporated for this express purpose. Pending receipt of all results from the current drill program, Delta will continue gold exploration at Mt Ida to grow the MRE in size and confidence, advance metallurgical and geotechnical studies and progress with 6 ASX ANNOUNCEMENT 24 January 2025 feasibility work for a standalone processing plant. While this development work continues, the Company maintains all optionality with regard to the gold assets at Mt Ida. Primary modifying factors (Geotechnical, Metallurgy) are being advanced to DFS level while GR Engineering have been contracted to carry out processing plant design and cost studies. These studies are running in conjunction with the submission of the Works Approval, which is planned within coming months.

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 50 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 techniques Drill type (e.g. core, reverse circulation, openhole 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). Commentary • • • • • • • • • • • • Reverse circulation (RC) drilling has been carried out by DLI at the Mt Ida Project RC samples are collected from a static cone splitter mounted directly below the cyclone on the rig DD sampling, when completed is generally carried out to lithological/alteration domains with lengths between 0.31.1m Historical data has been supplied by the previous project owner (Ora Banda Ltd), reverse circulation (RC) drilling and diamond drilling has been completed at the Project.. Limited historical data has been supplied, historic sampling has been carried out by Hammill Resources, International Goldfields, La Mancha Resources, Eastern Goldfields and Ora Banda Mining, and has included RC, DD and rotary air blast (RAB) drilling Historic sampling of RC drilling has been carried out via a static cone splitter mounted beneath a cyclone return system to produce a representative sample, or via scoop. Reports suggest that historic sampling of DD core has been completed to constrain mineralisation and to lithological boundaries. These methods of sampling are considered to be appropriate for this style of exploration Diamond drilling is generally carried out by Frontline Drilling utilising a Sandvik DE880 truck mounted multipurpose rig and is HQ or NQ diameter. RC drilling is carried out by Orlando Drilling using a Schramm T685 rig Some RC precollars will be completed, diamond tails will be completed in the coming weeks on these holes Historic RC drilling was completed using a T450 drill rig with external booster and auxiliary air unit, or unspecified methods utilising a 133mm face sampling bit It is assumed industry standard drilling methods and equipment were utilised for all drilling 13 ASX ANNOUNCEMENT 24 January 2025 Criteria Explanation 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. Commentary • • • • • 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. • • • • • • Sample condition is recorded for every RC drill metre including noting the presence of water or minimal sample return, inspections of rigs are carried out daily Recovery on diamond core is generally recorded by measuring the core metre by metre Poor recoveries can occasionally be encountered in near surface drilling due to the weathered nature RC recoveries were visually estimated on the rig, bulk reject sample from the splitter was retained on site, generally in green bags for use in weighing and calculating drill recoveries at a later date if required Sample weights were recorded by the laboratory Quantitative and qualitative geological logging of drillholes adheres to company policy and includes lithology, mineralogy, alteration, veining and weathering Diamond core and RC chip logging records lithology, mineralogy, alteration, weathering, veining, RQD, SG and structural data All diamond drillholes and RC chip trays are photographed in full A complete quantitative and qualitative logging suite was supplied for historic drilling including lithology, alteration, mineralogy, veining and weathering No historic chip photography has been supplied Logging is of a level suitable to support Mineral resource estimates and subsequent mining studies 14 ASX ANNOUNCEMENT 24 January 2025 Criteria Explanation 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. 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. Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. 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. Commentary DD sampling is generally undertaken by lithological/alteration domain to a maximum of 1.1m and a minimum of 0.3m. Core is cut in half with one half sent to the lab and one half retained in the core tray • Occasional wet RC samples are encountered, extra cleaning of the splitter is carried out afterward • When pegmatites are intercepted, RC and core samples are analysed for Li suite elements by ALS Laboratories, Samples are crushed and pulverised to 85% passing 75 microns for peroxide fusion digest followed by ICPOES or ICPMS determination • When potential Au/Cu lodes are intercepted, RC and core samples are analysed first via Photon / Fire assay methods and then subsequently MICP61 L for the base metal suite by ALS Laboratories, Samples are crushed and pulverised to 85% passing 75 microns before 4 acid digest with ICPMS finish or fire assay with ICPMS finish • Samples analysed via photon assay at ALS are dried and crushed to 3mm with 500g of material utilised for the analysis • To ensure a robust geochemical database and to ensure all mineralisation haloes are captured for MRE purposes, in some cases samples are submitted for both the Li suite and the Photon/FA & MICP61 L. This is due to the spatial relationship between the Au/Cu lodes and the LCT pegmatites. • Historic RC sampling methods included single metre static cone split from the rig or via scoop from the green bags, field duplicates were manually inserted at a rate of within the pegmatite / gold zones • Historic samples were recorded as being mostly dry • Historic samples were analysed by Nagrom or ALS Laboratories where 3kg samples were crushed and pulverised to 85% passing 75 microns for a sodium peroxide fusion followed by ICP-MS determination for 25 elements. • Semi-Quantitative XRD analysis was carried out by Microanalysis Australia using a representative subsample that was lightly ground such that 90% was passing 20 µm to eliminate preferred orientation TIMA sampling was also completed on pulverised lab • pulp material, this was completed to quantify the mineralogical makeup of pegmatites in particular. • Various samples from across the Au/Cu orebodies were extracted and sent to ALS laboratories for subsequent metallurgical analysis and flowsheet development. Samples have been analysed by an external laboratory utilising industry accredited standard method. The assay method utilised by ALS for core sampling allows for total dissolution of the sample where required Standards and blanks are inserted at a rate of 1 in 20 in RC and DD sampling, all QAQC analyses were within tolerance The sodium peroxide fusion used for historic assaying is a total digest method All historic samples are assumed to have been prepared and assayed by industry standard techniques and methods In the historic data field duplicates, certified reference materials (CRMs) and blanks were inserted into the sampling sequence at a rate of 1:20 within mineralised zones. Internal standards, duplicates and repeats were carried out by Nagrom and ALS as part of the assay process No standards were used in the XRD/TIMA process • • • • • • • • . • 15 ASX ANNOUNCEMENT 24 January 2025 Criteria Explanation Verification of sampling and assaying The verification of significant intersections by either independent or alternative company personnel.
