Ballard is pursuing a dual stream Resource Growth and Project Development strategy and aiming to announce a Maiden Ore Reserve at Baldock mid-year. The Company’s focus for CY2026 is Resource Growth to deliver production uplift in addition to Baldock as well as a longer mine life for a standalone operation. The Mt Ida Gold Project is located 540km northeast of Perth in the Goldfields region of Western Australia (Figure 1). The Mt Ida Gold Project covers 26km of prospective greenstone belt, folded around the Copperfield Granite (Figure 2). Figure 1 - Ballard’s Mt Ida Gold Project, located in Western Australia’s Goldfield Region. 3 ASX: BM1 ballardmining.com.au Figure 2 – Mt Ida Project 13km Ballard Fault 4 ASX: BM1 ballardmining.com.au Project Development A Maiden Ore Reserve for Baldock is scheduled for release mid-CY2026. This will be based on the February 2026 MRE update which included 669koz @ 3.7g/t1 of Indicated material at Baldock. The Indicated material is expected to convert to a 400-500koz Ore Reserve based on material modifying factors including Metallurgical and Geotechnical studies as below. Metallurgical and Process Plant Studies Ballard is advancing metallurgical studies to a Feasibility Level of detail for the Baldock Deposit. Metallurgical studies are 80% complete and results to date continue to demonstrate that the orebody is amenable to a conventional CIL gold processing circuit with an overall average +91% metallurgical recovery for both open pit and underground (Appendix B). Process Plant studies are underway and will form the basis of the Capex/Opex estimates for the Feasibility Study due mid-year. The Process Plant study will also provide the deliverables that will allow Ballard to undertake an EPC tender for the construction of the Processing Plant. This is expected to occur in H2CY2026 as the Company advances towards a Final Investment Decision (FID). Consultants Nexmin are completing both the Metallurgical and Process Plant studies. Geotechnical Studies Ballard is advancing geotechnical studies to a Feasibility Level of detail for the Baldock Deposit. Open pit geotechnical studies contemplate long term access for the underground portal locations. The global underground parameters are based on insitu rib and sill pillars with opportune unconsolidated waste back fill. Engineered backfill such as paste fill is not considered. Geotechnical investigation drilling and core logging work has been completed. Geotechnical assessment and analysis work is well advanced. Geotechnical studies are being undertaken by consultants Peter O'Bryan and Associates. Additional Production Bores Ballard has an approved water abstraction licence of 2.5 GL/yr from the Lake Raeside Paleochannel located approximately 30km north of the Mt Ida Project location (Figure 3). The borefield location is connected to the Project site by an approved Miscellaneous License (L29/229) which allows for the construction of the bore field, pipeline and access road. Ballard has previously installed three production bores at Lake Raeside to secure the water license fromDWER. As part of ongoing de-risking for Project execution,the Company nowplans to install an additional four production bores. This will provide the necessary number of production bores for a sustainable 2.5 GL/yr abstraction from the paleochannel. Aircore drilling is underway to refine the final location of the production bores (Figure 4). Conventional dewatering during planned open pit and underground mining operations is approved by a separate 1.2 GL/yr abstraction licence. Including the 2.5 GL/yr from the Raeside Paleochannel the total approved water abstraction license is 3.7 GL/yr. 1 Refer to the ASX Announcement released by Ballard on the 26 February 2026 for further information 5 ASX: BM1 ballardmining.com.au Figure 3 - Mt Ida Tenure highlighting recently approved Miscellaneous License for the bore fields 6 ASX: BM1 ballardmining.com.au Figure 4 - Aircore drilling to refine location of Production Bores in Lake Raeside Paleochannel Expansion of Mt Ida Exploration Camp An additional eight rooms are being installed at the existing exploration camp (Figure 5). This will expand the camp to thirty rooms. The additional rooms will be used by personnel undertaking early works scopes and ultimately the contractor who will build the accommodation village to house the construction workforce on a favourable FID. 7 ASX: BM1 ballardmining.com.au Figure 5 - Site preparation for additional accommodation units Mt Ida Public Road diversion The Company is planning on undertaking a public road diversion in H2CY2026 ahead of FID (Figure 6). This will minimise any interaction with public traffic and construction activities. The road diversion is fully approved. Ballard has commenced a tender process for the construction as well as engagement with local stakeholders. Appointment of Debt Advisor The Company is pleased to announce the appointment of Bedrock Advisory Partners (Bedrock) to assist in the assessment and management of the debt portion of Ballard’s financing process for the stand-alone development of the Mt Ida Gold Project. Bedrock is an independent specialist project finance advisory firm with deep experience in structured and project debt for natural resources developments. The Bedrock team will work alongside the Company’s Finance Director, Mr Tim Manners, to review and assess the optimal funding mix for the Project. Bedrock’s leadership team has decades of natural resources finance experience with firms such as BNP Paribas, Royal Bank of Canada and NM Rothschild & Sons. 8 ASX: BM1 ballardmining.com.au Figure 6 - Mt Ida Public Road Diversion 9 ASX: BM1 ballardmining.com.au Project Background The Mt Ida Gold Project hosts a JORC 2012-compliant Mineral Resource Estimate totalling 12.2 million tonnes @ 3.0 g/t Au for 1.2 million ounces2 of contained gold (Inferred and Indicated). The Baldock deposit, which hosts 1.0Moz @ 3.5 g/t2 forms the basis for initial development opportunities at Mt Ida. The Project includes six granted mining leases and is fully permitted for mining including an approved Mining Proposal, Mine Closure Plan and Native Vegetation Clearing Permit. Mining approvals are in place for both open pit and underground mining at the Baldock deposit. A Works Approval for up to 2.0 Mtpa Processing and Tailings Storage Facility has been received as well as granted 3.7 GL/yr water abstraction licences. -END- This release is authorised by the Board of Directors of Ballard Mining Limited.

This has meant a reduced residence time for oxide/transition, given a lower solids concentration is required due to the viscosity. Based on this, the 12-hour recovery numbers are used for the oxide/transition and 24-hour recovery for fresh as per the Tables below. Au_C is calculated from the results of the leach test (gold in solution and gold in residue) whereas Au_A is from the head assay. Given some of the variability within the head assay results, calculated values are shown.
