Yari Resources Limited | ASX: YAR | Quarterly Activities Report – September 2026 Page 1 ASX: YAR Highlights Acquisition of Arcadia Coal Project, Qld (completed post-quarter), more than doubling Yari’s coal resources to more than 500 million tonnes in the world-class Bowen Basin Multiple product pathways identified at Arcadia, including potential for semi-soft coking, PCI and high-energy thermal coal Post-quarter: Yari’s principal place of business moved to Brisbane, strengthening Yari’s Qld presence and supporting its coal expansion strategy in the Bowen Basin Yari continuing engagement with potential strategic partners and traders, with a focus on district-scale consolidation and further resource growth to increase shareholder value. Yar i Resources Limited (ASX: YAR) (“Yari” , “YAR” or “the Company ”) further advanced its Queensland coal expansion during the period ending 30 September 2026, highlighted by the acquisition of the Arcadia Coal Project. Arcadia Coal Project Acquisition Yari announced on 3 August 2026 its a greement to acquire a 100% interest in Northern Comet Resources Company, holder of the Arcadia Coal Project (EPC 1054, EPC 1772 and EPC 1042) in Central Queensland’s Bowen Basin. EPC 1772 hosts a reported JORC 2012 Mineral Resource estimate of 282Mt (164Mt Indicated, 118Mt Inferred), with the project located within the broader Rolleston coal district, regionally proximate to Yari’s Rolleston South Coal Project (Figure 1). The acquisition more than doubles Yari’s reported JORC Coal Resources to more than 500 million tonnes, advancing the Company’s strategic district -scale consolidation in the Rolleston coal district amid rising competition for resources within the tier-one Bowen Basin. The acquisition has been structured with low upfront consideration, with the majority of value linked to project milestones, initial commercial production and gross revenue royalty. Y ari’s Managing Director, Courtney Taylor, commented on the acquisition : “This is about turning Rolleston South from a standalone project into the foundation of a much larger regional opportunity. Arcadia gives Yari additional scale, more geological data and a broader platform to assess long- term development options across the Rolleston coal district. Importantly, the transaction is structured so that the major consideration is linked to project success.” Yari Quarterly Activities Report September 2026 ASX Announcement PERIOD ENDING 30 September 2026

The estimate (Jones 2017) is summarised in the table below. Table 1: Arcadia Coal Project (EPC 1772) – JORC (2012) Coal Resource (million tonnes, 11% in situ moisture basis)1 Seam Bandanna Formation Seam Indicated (Mt) Inferred (Mt) Total (Mt) Rider A - - - Aries 1 BU 47.5 32 80 Aries 2 BL 26.1 19 45 Castor 1 CU 8.9 7 16 Castor 2 CL 23.1 17 40 Pollux 1 DU 17.1 13 30 Pollux 2 DL 41.4 30 71 TOTAL 164.0 118.0 282.0 1 Figures may not sum exactly due to rounding. Resources reported at an in-situ moisture of 11% (Preston & Sanders formula). Resources are limited by a maximum cumulative waste-to-coal ratio of 15:1 bcm/t in situ within the mask area. Seam names used by JB Mining are those for the Rangal Coal Measures, rather than the Bandanna Formation nomenclature commonly used in mining operations at Rolleston and Meteor Downs Coal Mines, and Rolleston South deposit. Rider seam generally <0.5m and no resources reported by JB Mining.
Page 3
Yari Resources Limited | ASX: YAR | Quarterly Activities Report – September 2026 Page 3 A review of the JB Mining Resource Report by ROM Resources found generally no major issues and similar tonnages with some minor variation (<15%) possibly due to the different modelling packages used (Datamine Minescape versus Maptek Vulcan). A fuller assessment will be undertaken once all the geological, geotechnical, and coal quality data has been transferred and examined. Multiple Product Pathways A coal quality review announced on 7 September 2026 identified the potential for multiple product pathways from the Arcadia Coal Project, including semi-soft coking, PCI and high-energy thermal coal products. The Company is also assessing the potential for resource growth with an expansion of Arcadia’s technical dataset, including five cored petroleum/coal seam gas (CSG) wells not incorporated into the previous 2017 geological model. The independent coal quality review was conducted by coal quality specialist Chris McMahon of McMahon Resources, which reviewed historical data from 44 bore cores and 1,472 samples across the principal B, C and D seams of the Bandanna Formation. The review indicated average in-situ ash of approximately 10% and identifie d the potential for Arcadia to support multiple coal products, including semi-soft coking, PCI and high- energy thermal coal. Importantly, the results indicate Arcadia may offer flexibility to target different products from different parts of the deposit, rather than being developed around a single coal specification. Yari and McMahon Resources will now undertake detailed analysis to define the potential product proportions, yields, specifications and beneficiation requirements across the coking, PCI and thermal pathways. This work will help determine the optimum product strategy for Arcadia as part of Yari’s broader Rolleston district coal strategy. Acquisition Completion Post-quarter, on 20 October 2026 Yari announced the completion of the Arcadia acquisition, comprising A$50,000 upfront cash and 147,594,744 completion shares, subject to 12 months’ escrow. Using the A$0.0045 placement price as an illustrative reference, the cash and completion shares represent approximately A$714,000, equivalent to approximately 0.25 cents per reported Arcadia resource tonne. This is not the total acquisition cost or an accounting fair-value assessment. Additional obligations include A$400,000 minimum qualifying expenditure over three years; A$1.25 million in resource and tenure milestone payments; A$20 million in production-linked cash payments; a 1.5% gross revenue royalty; and a 10% entitlement to any relevant future sale or transfer consideration. The transaction also includes security, guarantee and vendor right -of-return provisions, as detailed in the clarification announcement released on 7 August 2026. Resource growth has exceeded the increase in shares on issue, lifting both total and Indicated resource tonnes per share. Per -share figures are calculated using the 839,463,804 pre -transaction shares on issue and 1,475,644,105 post-completion shares on issue, with percentage changes calculated on unrounded figures.

Yari Resources Limited | ASX: YAR | Quarterly Activities Report – September 2026 Page 4 Completion of the Arcadia acquisition has lifted Yari’s reported JORC Coal Resources to 504.9Mt, more than six times the 78.9Mt initially reported for the Company’s Rolleston South Project in May 2025. Indicated Resources have increased from 33.7Mt to 197.7Mt, with Arcadia contributing 164.0Mt Indicated. (Note: combined figures are the sum of separately reported Mineral Resources. No new estimate or reclassification has been announced). Figure 2: Growth in Yari’s reported JORC Coal Resources since May 2025. Sources: Yari announcements dated 7 May 2025, 28 August 2025, 2 February 2026 and 7 August 2026. With the Arcadia acquisition now complete , Yari’s focus shifts to unlocking value from its expanded 504.9Mt Queensland coal resource portfolio through: Resource growth and project advancement initiatives at Arcadia and Rolleston South. Technical and development studies aimed at progressing both projects towards future development decisions. Evaluation of strategic opportunities that enhance shareholder exposure to Queensland coal resources. Review of Operations Rolleston South and Arcadia Coal Projects (Queensland) During the quarter, Yari progressed the compilation and validation of a unified drilling and coal quality database across the Rolleston South and Arcadia Coal Projects, combining results from the 2025 Rolleston South drilling program and ongoing coal quality testwork with Arcadia’s historical drilling and coal quality data . The unified database will underpin updated geological modelling across both projects and a more targeted approach to future drilling, consistent with Yari’s district-scale strategy in the Rolleston coal district. The Rolleston South Coal Project is located in Queensland’s Bowen Basin, one of the world’s most established coal provinces (Figure 3 ), and is located near several operating coal mines. The project is considered to have potential to produce an export -quality thermal coal product, with additional upside for semi- soft metallurgical applications. 197.778.9 190.1 222.9 504.9 0 100 200 300 400 500 600 May 2025 Aug 2025 Feb 2026 Sep 2026 JORC Coal Resource (Mt) Indicated Inferred

This work is critical to evolving a more targeted drilling strategy, focused on further improving resource confidence, delineating shallow coal zones and supporting future development studies. Yari continued to advance engagement with potential strategic partners and commodity traders, consistent with its strategy to progress the Rolleston South Coal Project through joint venture and offtake pathways. Further updates, including additional coal quality results, refined geological interpretations and outcomes from targeted drilling activities, are expected in coming periods as Yari continues to advance the Rolleston South Coal Project towards the next stage of development.
