The 4-stage extensional drill program has continued to deliver strong results and have confirmed more gold across the broader tenure of Mt Ida. Importantly, the Company is progressing concurrent workstreams to accelerate Mt Ida’s development including the submission of a Works Approval application to the Department of Water and Environmental Regulation to construct a gold Processing Plant and Tailings Storage Facility with the potential capacity of processing and tailings deposition of up to 1.5Mtpa. 1 Refer ASX Announcement 27 August 2024 titled ‘Delta continues to advance Mt Ida Gold Project’ 2 Refer ASX Announcement 28 June 2024 titled ‘Major Upgrade to Mt Ida Gold Resource’ ASX ANNOUNCEMENT 26 March 2025 Commenting on the Mt Ida Project Update Managing Director, James Croser said; “These continued high-grade extensional results bode well for the planned gold MRE update, with Delta aiming to grow substantially upon our current 752,000 oz MRE at Mt Ida. The Company continues to search for the edges of mineralisation at Baldock and test our regional prospects, with numerous exploration targets already identified for future drill programs. The first assays back to Delta from the Bombay-West KnellJupiter prospects have confirmed more gold across a wider expanse of our regional tenure, with assays still pending for 26 holes in the lab. The recently submitted Works Approval application for onsite gold treatment is a critical step for Delta, being the only outstanding permit required for Delta to construct a gold plant and TSF at Mt Ida, and is the culmination of many hours of diligent work by Delta staff. The broader gold landscape remains extremely strong with the spot price reaching record highs in recent months. Delta’s longer-term strategy remains the continued advancement of the Mt Ida Gold Project towards genuine standalone scale.” Mt Ida Exploration Update Mt Ida is located 100km northwest of Menzies, and approximately 225km by road from 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. Two drill rigs are currently operating at the project, focussed on resource extensions and resource growth with a target to grow the current 752,000oz @ 3.5g/t gold Mineral Resource Estimate, including the high grade Baldock deposit of 4.8Mt @ 4.4g/t gold for 674,000oz. Delta’s recent exploration results are very promising and provide further confirmation of historical tenor and potential of the broader Mt Ida Gold Project. Additional Intercepts at Baldock continue to deliver exceptional extensions to deep high-grade resources including the delineation of an additional enechelon lode in the footwall of the lode 90 which hosts 504kt @ 6.9g/t Au for 112kOz1 – See Figure 2.This new lode is completely open to the South and will add to the current resource base at Baldock of 674kOz @ 4.4 g/t Au, which acts as the baseload of the Mt Ida Gold Project. Figure 1: Overview showing DLI Projects & Resources 2 ASX ANNOUNCEMENT 26 March 2025 Figure 2: Cross- section showing Baldock deep lodes beyond the current MRE and new high-grade structure that remains open to the South. (Refer to white dashed line in Figure 3 for location of cross section) The Company believes this newly identified footwall lode beneath lode 90 presents a compelling exploration target and will be further tested by future drilling. Previously released results from the extensional Baldock drilling include the following significant intercepts as shown in Table 1. See Figure 3 for illustration of these recent intercepts in relation to the current Mineral Resource Estimate at Baldock.

All exploration results will feed into the updated Mineral Resource Estimate scheduled to be completed in the June Quarter, which is planned to be followed by an infill resource conversion campaign. There are still 5 ASX ANNOUNCEMENT 26 March 2025 more than 26 holes undergoing testing in the lab while further drilling at the Saturn and Unexpected prospects will be commencing in the next week with the aim to further grow the Mt Ida regional resources. Figure 5: 200m wide West Knell section facing West showing previous and recent significant intercepts (historic drillhole information can be found in Appendix 3) Works Approval Delta has submitted a Works Approval application for onsite gold treatment and tailings deposition, being the only outstanding permit required for Delta to construct a gold plant and TSF at Mt Ida. The Works Approval application process may take up to six months. The timing of this submission and approval process aligns with ongoing workflows at Mt Ida, which are currently focused on completion of the current resource growth drilling and an updated MRE early in the June Quarter. Next Steps Stage 4 of the extensional drilling campaign at the Mt Ida project will be completed early in the June Quarter. Outstanding assay results of the completed program, and indeed all results combined from the 4-stage extensional program will form the basis of an updated Gold Mineral Resource Estimate. The Company will look to release this update early in the upcoming June quarter. 6 ASX ANNOUNCEMENT 26 March 2025 Future planning for Mt Ida includes the commencement of infill drilling, at Baldock in particular, and at sufficient density to underpin a multi-year Mining Plan and maiden Reserve statement. This planned infill drilling program will target the conversion of remaining inferred material up to 250m depth at Baldock to Indicated status, as well as geotechnical and metallurgical data collection to support a full Feasibility Study, inclusive of an onsite processing scenario for all potential ore production.

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
