HIGHLIGHTS Miriam • Reverse Circulation (RC) drilling recommencing at the Miriam Gold Project (Miriam) in late October 2026, targeting extensions to the emerging gold system at the flagship Forrest Prospect (Forrest) and follow-up drill testing of the Burbanks Monarch prospect (Burbanks Monarch). • Initial Mineral Resource Estimate (MRE) and Exploration Target (ET) for Miriam expected later in Q4 CY2026. • First-pass RC and aircore (AC) drill testing to be conducted at priority regional prospects including Devil’s Playground, Burbanks Grand Junction and Bell Bird in early CY2027. • Environmental surveys and baseline waste rock and water studies scheduled to advance Miriam through permitting and support potential mine development. Avoca • Broader regional exploration commencing with initial testing of the Avoca Gold Project (Avoca). o Heritage clearance surveys completed. o Soil sampling programme finalised, with results expected early-mid October 2026. o Programme of Work (PoW) approved, with initial AC drilling scheduled to commence in mid- October 2026. • AC drilling to then target the Mt Monger Gold Project (Mt Monger), part of the Kal East Gold Projects. Kal East Gold Project update to come in later October. o PoW approved with heritage clearance surveys underway to support upcoming field activities. • Ore is well funded and strongly positioned to advance all planned exploration across its WA Goldfields portfolio, with a robust cash balance of A$6.8 million and zero debt (as at 30 June 2026). Ore Resources’ Managing Director and CEO, Nick Rathjen, commented: “We are excited to outline an active exploration strategy at the Coolgardie Gold Projects with a significant body of work planned over Q4 2026 and into 2027.” “At Miriam, upcoming RC drilling will focus on further extending the emerging high-grade gold system at Forrest along with follow-up testing of gold discovery potential at the Burbanks Monarch prospect. Continued success at Forrest is expected to support the delivery of an initial MRE and exploration target, representing the next major milestone for our gold project portfolio.” “In parallel, metallurgical, environmental and other technical studies are progressing to support permitting activities and future project development.” oreresources.com.au 2 "Our upcoming programmes will also include initial AC drilling at Avoca. Cultural heritage surveys are now complete, and a project-wide surface geochemistry programme has been finalised. The surface geochemistry results are expected in early October 2026, to refine and prioritise drill targets ahead of first pass drilling.” “Avoca represents a compelling gold exploration opportunity, characterised by multiple historical intercepts of high-grade gold mineralisation. Our review of the historical data has highlighted the potential for both shallow oxide mineralisation and largely untested primary gold lodes. The upcoming drilling programme will provide the first systematic test of these targets, offering considerable potential to further demonstrate the broader prospectivity of the project.” “Following the completion of AC drilling at Avoca, we will turn our attention to Mt Monger, part of the broader Kal East Gold Projects. The planned programme will represent our first drilling undertaken at Kal East and marks an important step in expanding our exploration footprint across the Eastern Goldfields. We see an exciting gold growth opportunity at Kal East and will be providing a project update in the coming weeks.” “With exploration programmes planned across Miriam, Avoca and Mt Monger, the coming months are shaping up to be a highly active period for the Company. Ore remains well funded and well positioned to unlock additional regional gold opportunities while advancing Miriam through resource definition, permitting and technical de-risking activities in support of future development.” Exploration drilling recommencing at the Coolgardie Gold Projects Ore plans to advance a range of exploration and project development activities across its Coolgardie Gold Projects during Q4 2026, with a primary focus on Miriam. As part of its ongoing 30,000m Phase 4 drilling program, the Company intends to recommence RC drilling at Miriam in late October 2026. This programme will comprise approximately 3,000m of drilling, including extensional drilling at the Forrest Prospect and follow-up drilling designed to test fresh-rock gold mineralisation at Burbanks Monarch. Results from the programme are expected to support the delivery of an initial MRE and ET for Miriam and contribute to defining a broader exploration target anticipated later in Q4 2026. Ore has also commenced preliminary metallurgical testwork on drill core from Forrest to assess the amenability of the mineralisation to conventional gold processing methods. In parallel, spring flora and fauna surveys, together with baseline waste rock characterisation and water studies, are scheduled at Miriam. These programmes represent key components of the environmental approval process and will be undertaken concurrently with environmental studies at the Kangaroo Hills Lithium Project. Following the recent consolidation of the Miriam tenure package0F 1 , first-pass regional RC and AC drilling is also scheduled to commence in early 2027, targeting several high-priority target areas across the Devil's Playground, Burbanks Grand Junction and Bell Bird prospects. Collectively, these workstreams are designed to advance Miriam through resource definition, permitting and technical de-risking, while continuing to unlock the broader development potential of Ore's Coolgardie Gold Projects. 1 Refer to OR3 ASX release dated 2 September 2026, “Consolidation of Miriam Gold Tenure Completed and Cleansing Statement” oreresources.com.au 3 Figure 1: Miriam – Plan View oreresources.com.au 4 Broader regional gold prospectivity In addition to advancing exploration at Miriam, the Company plans to conduct broader regional exploration activities, beginning with first-pass drill testing of Avoca, located to the north of Miriam. Cultural heritage surveys have now been completed, representing an important milestone prior to planned drilling activities. Ore has also completed a project-wide surface geochemistry programme, utilising Ultrafine+™, an Ultra Fine Fraction (UFF) process co-developed by CSIRO and LabWest. Ore has successfully deployed this technique during its previous soil sampling programmes at Miriam1F 2 . As part of the surface geochemistry programme at Avoca, Ore collected approximately 700 UFF samples with the aim of identifying near-surface gold anomalism within the regolith profile. Assay results are expected in early October 2026 and will be used to refine drill targeting ahead of the maiden AC drilling programme, scheduled to commence in mid-October. Avoca comprises 6.7km² of prospective exploration tenure located along the highly endowed Kunanalling Shear Zone, a major structural corridor hosting mafic, ultramafic and sedimentary rock units. Historical exploration and prospecting activities across the tenure have highlighted numerous mineralised gold trends, including a standout intercept of 4m @ 14.04 g/t Au from 36m within 44m @ 1.84 g/t Au from 16m (AVRC002)3 . Other key significant historical intercepts include2F 3 : • 4m @ 1.49 g/t Au from 41m (AVR244) • 3m @ 1.68 g/t Au from 30m (AVR284) • 4m @ 1.47 g/t Au from 28m (AVRC007) • 3m @ 2.13 g/t Au from 35m (AVR040) • 1m @ 2.04 g/t Au from 16m (AVR264) • 2m @ 1.48 g/t Au from 47m (AVR0703) Ore's review of historical drilling also defined a mineralised trend extending approximately 300m along strike in the southern portion of the project area. This trend hosts several economic-grade gold intersections yet remains only sparsely drill tested. Mineralisation identified to date is largely confined to shallow regolith, highlighting the potential for near-surface oxide gold mineralisation. Importantly, the primary fresh rock gold lodes, interpreted to be the source of the oxide mineralisation, remain largely untested by drilling, presenting a compelling opportunity to define additional gold mineralisation both along strike and at depth. PoWs have now been approved for both initial AC and future RC drilling at Avoca. Ore plans to commence AC drilling at Avoca before progressing to initial AC drill testing at Mount Monger (part of the Kal East Gold Projects). Drilling is scheduled to commence across both projects from mid October 2026. 2 Refer to OR3 ASX releases “Soil Sampling Results Identify 1.75km Gold Anomaly at Miriam” dated 25 June 2025, “Emerging Broad-Scale Anomalous Gold Trend Identified along the Miriam Shear Zone”, dated 4 February 2026 and “Expanded Soil Sampling Defines New Northern Gold Targets at Miriam”, dated 9 April 2026 3 Refer to OR3 ASX release “Expansion of Coolgardie Gold & Lithium Project” 16 March 2026 oreresources.com.au 5 Figure 2: Avoca – Plan View (including historical collars and significant intercepts) oreresources.com.au 6 Figure 3: Coolgardie Gold Projects – Location Map This announcement has been authorised for release by the Board of Directors of the Company.
