Announcement PDF ASX ANNOUNCEMENT 22 October 2025 SEPTEMBER QUARTERLY ACTIVITIES REPORT Delta Lithium Limited (ASX: DLI) (“Delta” or “the Company”) is pleased to provide a summary of activities undertaken during the quarter ended 30 September 2025. September Quarter Highlights • Ballard Mining Limited (ASX:BM1) commenced trading in July having been successfully spun-out of Delta’s Mt Ida gold rights via a demerger and concurrent IPO into a new standalone, gold-focused ASX-listed exploration company. o Eligible Delta shareholders received an in-specie distribution of one Ballard share for every 11.25 Delta shares held, effectively a capital return of $16M. o Delta retained significant upside exposure to Ballard with a substantial 46% shareholding. o The demerger and IPO of Ballard initially added $39M to the balance sheet of Delta (at the $0.25c per share issue price) to in excess of $82M1 at this report date. o The demerger has unlocked significant value for Delta shareholders and separated Delta’s gold and lithium assets into two distinct companies. • Delta to benefit from Ballard’s regional and in-fill drilling program at Mt Ida. o Following the successful spin-out of Delta’s Gold rights, infill gold drilling conducted by Ballard at Mt Ida intercepted notable lithium intervals including:  37m @ 2.05% Li2O from 217m  17m @ 1.47% Li2O from 144m  23m @ 1.04% Li2O from 212m • Detailed ground mapping and geochemical sampling to identify regional exploration targets for the current drill program at Yinnetharra. o Systematic geochemical sampling and mapping over priority areas have been conducted to determine targets for drill testing at Jamesons and adjacent prospects along the Leake Springs metasediment package in the December quarter • Database review highlights high grade rubidium contained in the Mt Ida pegmatites and investigations have commenced to determine potential co-product credits. • At the end of the quarter Delta had cash $56.8M. Commenting on the quarter, Managing Director of Delta Lithium, Mr James Croser said: “The most recent quarter was genuinely transformational for Delta. The demerger and subsequent IPO of our gold assets into Ballard Mining has resulted in a significant benefit to Delta’s balance sheet of more than $80 million, marked to market. Coupled with our existing cash balance of $57 million, Delta is now perfectly positioned to pursue growth from our lithium portfolio and options further afield. “Drilling has recommenced at Yinnetharra on priority targets along the 20km of Leake Springs unit linking our two MRE’s at Jameson to Malinda, testing extensions to Jameson’ mineralisation and seeking Lithium, Caesium, Tantalum pegmatite’s (LCT’s) on our newly acquired ground. 1 Based on closing price of Ballard Mining at 21 October 2025 ASX ANNOUNCEMENT 22 October 2025 “Mt Ida continues to grow in confidence, with some high-grade infill drill results from Sister Sam and the discovery of a new LCT pegmatite in the Sister Sam footwall. Ongoing metallurgy and mineralogy work has also indicated the presence of high-grade rubidium worthy of follow-up work over coming months.” MT IDA DEMERGER AND IPO During the quarter, Ballard Mining Limited commenced trading on the ASX following Delta’s successful completion of the demerger and Initial Public Offering (IPO) of its Mt Ida Gold Project into this new, standalone entity. This strategic separation allows Delta to focus on its core lithium business while providing investors with direct exposure to a promising gold exploration company. The Mt Ida Gold Asset is located approximately 100km northwest of Menzies, and approximately 225km by road from Kalgoorlie in Western Australia’s prolific Eastern Goldfields mining region. Figure 1: Mt Ida Project and Location of Gold Deposits Delta released an updated gold Mineral Resource Estimate (MRE) at the Mt Ida Project of a total Inferred and Indicated Mineral Resources of 10.3Mt @ 3.33 g/t Au for 1.1 Moz2 . This MRE update significantly increased the global gold inventory at the Mt Ida Project, demonstrating the presence of a large gold system, both immediately at Baldock and across the broader tenement package (see Figure 1) and represented 2 See ASX Announcement 29 April 2025 entitled “Mt Ida Gold Resources Update & Proposed Demerger” ASX ANNOUNCEMENT 22 October 2025 significant potential upside for future exploration at the Mt Ida Project. Given the scale of the Mt Ida Gold MRE and a potential future standalone mining operation, together with the funds required to continue advancing the Mt Ida Project towards execution, the Board and management of Delta made a strategic decision to demerge the Gold Asset into Ballard to drive superior value for Delta Shareholders and new Ballard Shareholders. The demerger and IPO have been an outstanding success with the Ballard share price appreciating more than 150% since listing. The demerger, which received very strong institutional and retail support, provided Delta shareholders with one Ballard share for every 11.25 Delta shares held, allowing shareholders to retain exposure to the value and upside of the Gold Asset. Ballard is driven by a high-calibre and experienced team with extensive experience in mineral exploration, project development, mining and financing in the resources industry. Tim Manners and Paul Brennan lead the executive team and carry their current knowledge of the asset over to Ballard to ensure a smooth transition of the Mt Ida Gold asset into the new standalone entity. Todd Hibberd subsequently joined as Exploration Manager. Simon Lill has been appointed Chairman and Stuart Mathews and James Croser are acting as Non-Executive Directors. The demerger was subsequently followed by a successful IPO and ASX listing on 14 July 2025, with an oversubscribed capital raising of $30 million. The capital has allowed Ballard to immediately commence a significant exploration, extensional and infill drilling program, including the drilling of regional growth targets and infill drilling at Baldock to support DFS workstreams and associated study work, with a view to reaching a final investment decision on building a gold mine at Mt Ida. Ongoing Exploration at Mt Ida Delta remains the tenement holder at Mt Ida and retains ownership of all minerals except for gold. The demerger provides Delta significant upside through a substantial holding in Ballard Mining, while enabling the Company to continue focusing on its primary business, being the exploration and development of its Australian lithium assets. Delta is also able to benefit from the Ballard regional and infill drilling programs. Where pegmatites are intercepted during the gold drilling programs, Delta has been assaying the pegmatites for lithium. Best results intercepted during the quarter (which were drilled obliquely) are outlined below; o 37m @ 2.05% Li2O from 217m in DFS399 (Sister Sam) o 17m @ 1.47% Li2O from 144m in IDRD381 (Sister Sam) o 23m @ 1.04% Li2O from 212m in DFS066B (Timoni) These new lithium results and a new pegmatite discovery are very encouraging for the Mt Ida Lithium Project and confirm the high potential of discovering further resources at depth and along strike of the existing Lithium MRE with future drilling. Furthermore, a thorough review of the Mt Ida database during the quarter has confirmed that the Mt Ida LCT pegmatite system also hosts high-grade rubidium, coincident and seemingly correlated with the existing high-grade lithium and tantalum mineralised zones. Very high-grade rubidium intercepts have been assayed, including intercepts of up to 5m @ 1.79% Rb2O in hole GCS0013. Table 1 below includes a selection of the many significant rubidium intercepts contained within the existing Mt Ida LCT pegmatites. The rubidium is completely contained within the existing MRE, potentially adding significant value as a co- product to the lithia production at the Mt Ida Project by reporting to the mica pre-float concentration part of the existing Mt Ida WOF flowsheet design. As a result, this new data will be incorporated into a MRE update for Mt Ida (inclusive of rubidium), which Delta aims to complete in the December Quarter.

YINNETHARRA LITHIUM PROJECT The Yinnetharra project, in the Gascoyne region of Western Australia, targets Lithium mineralisation, with Delta now owning more than 3,100 km² of tenure outright and as Farm-in Joint Ventures. A MRE update for Yinnetharra was released in March 2025 of 21.9 Mt @ 1% Li2O and 75ppm Ta2O5 and an additional 17.5Mt @ 136ppm Ta2O5. During the quarter, fieldwork activities continued at Yinnetharra including target generation soil geochemistry and detailed geology mapping to support planning for the recently commenced drill program. Additional heritage surveying to ensure the identification and preservation of important heritage sites was completed across all tenure locations in preparation for the upcoming RC drill program. Figure 2: Location of Delta’s Projects ASX ANNOUNCEMENT 22 October 2025 Jameson Jameson represents a high priority target in relation to exploration and resource growth. The current Jameson MRE of 0.8Mt @ 1.66% Li2O is open down plunge and will be tested during the RC drilling program. The area is structurally complex with several deformational and folding events. Structural analysis undertaken has improved understanding of the paragenesis and subsequent mineralisation which is hosted in these structural traps. The detailed structural review identified the F2 fold hinges and later stage faults as priority targets for future exploration. The current surface data correlates with this thesis, suggesting Lithium-enriched fluids have mobilised through these potential structural trap zones – see Figure 3). The majority of this Phase 1 drilling program is targeting these fold hinges, limbs and faults which possess elevated discrete surface anomalies and represent compelling targets. These targets have never been drill tested and have an identical structural setting to the J1 pegmatite. Figure 3: Plan View to Jameson with planned drilling ASX ANNOUNCEMENT 22 October 2025 Yinnetharra Regional Exploration As part of the regional campaign, exploration work has continued across the 3000km2 Project and JV tenure. The team have been conducting systematic surface exploration across prospective areas and generated over 25 prospects (Figure 4) with many areas not yet explored. This greenfields geological work comprised of detailed mapping, rock chip and auger sampling as well as a high-resolution drone magnetic survey (EM). The EM survey was completed in September and flown at 25m spacings and 20m vertical height to produce a high-resolution map which will aid with structural interpretations and target generation. The culmination of these greenfields geological workstreams has resulted in six priority drill targets that will be the focus of the Phase 1 drill program, all of which are hosted in the Leake Springs Metamorphics unit, the preferential host of Jameson and Malinda deposits – see Figure 4. Figure 4: Plan View to Yinnetharra MRE’s and drill targets for current exploration programs ASX ANNOUNCEMENT 22 October 2025 Mason’s Prospect is a 500m long target characterised by enriched Lithium, Caesium, Tantalum (LCT) pegmatites located 3km along strike from Jamesons within the same host rocks. The first phase of drilling will target these northwest trending pegmatites at depth and along the defined strike. Yamazaki Prospect represents a compelling exploration target sitting just 8km from Jameson and 12km from Malinda along the margin of the continuous Leake Springs unit. It hosts a 4km long Lithium surface geochemical anomaly that has never been drilled – see Figure 5. First pass drilling will focus on the primary Lithium anomalies while Phase 2 and 3 drilling have been planned pending successful results. Figure 5: Plan View to Yamazaki prospect showing surface anomalism North Talisker and Caribou both represent strong targets with each hosting consistent LCT signatures and rock chips as high as 822ppm Ta2O5. North Talisker has never been drilled while only 13 holes were completed at Caribou South last year with follow up work identified at that time. East Calypso Prospect is one of the highest ranked targets beyond Jameson. This prospect sits immediately adjacent to the Thirty-Three suites Granite within the Leak Springs which is a mirror image of the geological setting at the Malinda deposit. Contrary to the general LCT models, the 21.1Mt @ 1% Li2O at Malinda is located only a few hundred metres away from the apparent source Granite which is identical to East Calypso to the South. East Calypso is also strengthened by the same host rocks and consistently high Lithium / Caesium levels in the surface dataset, while Caesium is generally very immobile and does not travel far from the source – see Figure 6. These E-W trending pegmatites will be tested thoroughly during this current program.
