I.e., AuEq = ((Au Produced x Au $/oz) + (Sb Produced pre-payability x 70% payability x Sb $/t)) / (Au $/oz). The average market prices for the quarter were A$5,283/oz Au (being the average of the daily PM price, sourced from www.lbma.org.uk) and A$33,508/t Sb (being the average Shanghai Metal Market Price sourced from www.metal.com). The average market prices for the statutory reporting period were US$5,382/oz Au (being the average of the daily PM price, sourced from www.lbma.org.uk) and A$33,859/t Sb (being the average Shanghai Metal Market Price sourced from www.metal.com). AISC is a non-IFRS measure and does not have a standardised meaning under IFRS and might not be comparable to similar financial measures di sclosed by other companies. Refer to "Non-IFRS Performance Measures" at the end of this announcement. 2 Group Production on basis of 100% contribution from Tomingley, Costerfield and Björkdal for the quarter. As the merger with Mandalay Resources completed on 5 August 2025, Alkane’s statutory reported production for FY2026 reflects production from Costerfield and Björkdal only from that date. Full quarter production and costs can be found at the end of this report. 3 Refer to ALK Announcement dated 9 September 2025 titled ‘Alkane Announces Financial Year 2026 Guidance’ for calculation of gold equivalent ounces and definition of Group Guidance.

2/14 Alkane Resources Limited – 30 September 2025 Quarterly Report – 29 October 2025 Managing Director , Nic Earner , commented: “It has been a significant quarter with the merger with Mandalay completing in early August. Alkane now has three operating mines who together produced 35,527 ounces of gold and 198 tonnes of antimony (36,407 ounces of gold equivalent) over the full quarter. 1,2 With the repayment of our A$45 million debt and the one-off transaction costs of A$25 million behind us we have a very solid balance sheet with A$191 million in cash, bullion and listed investments at quarter end.” GROUP SUMMARY STATUTORY REPORTING PERIOD Gold-Antimony Production During the quarter, Alkane produced a Group record quarterly production of 30,511 gold equivalent ounces at an AISC of $2,988/AuEq oz.1 This was a transitional quarter with only 2 months of production from Björkdal and Costerfield. Alkane produced 29,965 ounces of gold and 124 tonnes of antimony in Q1 FY26, its highest quarterly gold and antimony production yet. This period included the expected slower production at Björkdal over the Swedish extended summer vacation period. Additionally, this result was from three months of production from the Tomingley operation (18,335 gold ounces) but only two months of production from the Costerfield (6,189 gold equivalent ounces 1) and Björkdal ( 5,987 gold ounces) operations. Alkane processed 571,429 tonnes of ore in total at an average gold grade of 2.27g/t Au producing 29,965 ounces of gold. Tomingley processed 314,970 tonnes of ore with an average gold grade of 2.15g/t. At Costerfield, the average grade of gold was 8.48g/t and the average grade of antimony was 0.68% over 22,671 tonnes of ore processed over two months while Björkdal processed 233,789 tonnes of ore with an average gold grade of 0.94g/t, also only over two months. Table 1: September 2025 statutory reporting period operational performance summary1 Revenue Gold equivalent sales for the quarter of 30,010 ounces 1 for revenue of A$147 million at an average gold price of A$4,896/oz and an average antimony price of A$35,646/t. Revenue from Tomingley includes 7,250 ounces delivered into forward contracts at an average A$2,832/ounce. Björkdal´s average realised gold price at A$6,335/oz is a simple average for the quarter of recognised revenue divided by ounces sold for the quarter . Provisionally priced concentrate sales are revalued at each reporting date by using the current market price at the end of each reporting period, which increased notably during the quarter leading to the recognition of additional revenue without recognising additional ounces, increasing the realised gold price per ounce.

5/14 Alkane Resources Limited – 30 September 2025 Quarterly Report – 29 October 2025 OPERATIONS AND PROJECTS Costerfield Gold-Antimony Operations - Victoria (Costerfield) Mandalay Resources Costerfield Operations Pty Ltd (100%) Costerfield gold-antimony operations is a wholly owned operation of Alkane. Costerfield is located within the Costerfield mining district of Central Victoria, Australia, approximately 10 km northeast of the town of Heathcote and 50 km east of the city of Bendigo. The Property encompasses the underground infrastructure supporting the Augusta, Cuffley, Brunswick, Youle and Shepherd deposits; the Augusta Mine Site (Augusta), the Brunswick Processing Plant; the Splitters Creek Evaporation Facility; the Brunswick and Bombay Tailings Storage Facilities (TSF) and associated infrastructure. Operations Performance Costerfield delivered steady operational performance during the quarter, maintaining strong mining productivity while advancing several initiatives to improve ore quality and recovery. Mining focused on achievement of planned high priority areas, with some variability in stope performance due to challenging ground conditions and overbreak in complex shallow dipping parts of the orebody in the Youle-Shepherd transition. The operation has implemented targeted improvement programs including drill and blast opt imisation, enhanced operator training, and the move to emulsion explosives to improve recovery and reduce dilution. Processing operations performed reliably, with higher mill throughput supported by improved crushing circuit availability. Continuous optimi sation of blending and recovery remains a focus. The site continues to prioritise operational consistency and grade control to underpin strong production outcomes over the coming quarters. A total of 6,189 gold equivalent ounces 1 was produced during August and September. The site cash costs for the quarter were A$1,927/AuEq oz with an AISC of A$2,451/AuEq oz.1 Gold sold for the quarter was 5,273 ounces at an average sales price of A$5,361/oz, generating revenue of A$28 million. Finished product stocks were 4,521 ounces. The site’s operating cash flow was A$20 million for the quarter. Exploration At Costerfield during Q1 FY26, near mine drilling continued on three main focus areas. Following the success of Brunswick South testing program (see ASX announcement dated 15 October 2025 and titled ‘Costerfield Resources and Reserve Statement FY25’) drilling continued with the aim of testing the extents of the high-grade intercepts drilled in Q4 FY25. Drilling also continued on the Sub KC program which aims to infill and grow Inferred Resources. Finally, extension drilling continued on the Kendal area just above the currently mined Youle and Shepherd deposits. Approximately 2km to the west of current development, the True Blue program continued with three drill rigs focused on infill drilling a portion of the Inferred Resources recently estimated (see ASX announcement dated 15 October 2025 and titled ‘Costerfield Resources and Reserve Statement FY25’).

Tomingley has been operating since 2014. Mining occurs underground on four gold deposits (Wyoming One, Caloma One, Caloma Two and Roswell). Operations Performance The primary source of ore continues to be from Roswell, during the quarter the ore production was negatively impacted by short term problems with explosives quality. Site has engaged with the supplier to rectify to minimise potential impacts in the future. A total of 18,335 ounces of gold was poured for the quarter. The site cash costs for the quarter were A$ 2,120/oz with an AISC of A$ 2,628/oz.1 Gold sold for the quarter was 18,456 ounces at an average sales price of A$4,284/oz, generating revenue of A$79 million. Bullion stocks were 2,417 ounces. The site’s operating cash flow was A$39 million for the quarter. Works formally commenced on the Newell Highway diversion, outside of the existing Newell Highway corridor, on TGO owned land in the last week of the quarter. In early October Tomingley awarded the final portion of t he contract to construct the Newell Highway re -alignment, including within the existing Newell Highway corridor. Construction is expected to take 12 months and complete in the March quarter 2027. Exploration Resource expansion drilling continues at Tomingley outside existing resource models and close to existing underground infrastructure, and an update is expected to be reported in October. Results from a regional drilling program around Tomingley has intersected significant gold mineralisation at El Paso (see ASX Announcement dated 14 August 2025 and titled ‘Tomingley Exploration Intersects Significant Gold at El Paso’ ). Including three zones of gold mineralisation hosted by a poorly defined dacite intercepted by EPD017 for 32.1m grading 1.65g/t Au, 14m grading 1.71g/t, and 8m grading 1.19g/t Au. 2,000 metres of diamond core drilling is underway to further define an exploration target for El Paso.
