ASX: ALK TSX: ALK OTCQX: ALKRY 4 Q2 & H1 FY2026: Highlights 1. Gold equivalent ounces calculated by multiplying quantities of gold and antimony in period by respective average market price of commodities in each quarter, adding the two amounts to get ‘total contained value based on market price’ and dividing that total contained value by the average market price of gold in each quarter. I.e., AuEq = ((Au Produced x Au $/oz) + (Sb Produced pre-payability x 70% payability x Sb $/t)) / (Au $/oz). Accumulated gold equivalent ounces are derived by adding together each quarter´s number of calculated gold equivalent ounces during the financial year. Average market prices for gold and antimony sourced respectively from LMBA daily PM price (www.lmba.org.uk) and Shanghai Metal Market Price (www.metal.com). Average market prices for Q2 2026 quarter were A$6,299/oz Au and A$30,245/t Sb and for Q1 2026 were A$5,382/oz Au and A$33,859/t Sb using an AUD: USD exchange rate of 0.6565 and 0.6542 respectively. Gold equivalent ounce is a non-IFRS performance measure with no standard definition under IFRS. For more details refer to the Non- Performance Measures section of the MD&A. 2. As the merger with Mandalay Resources completed on 5 August 2025, Alkane’s FY2026 statutory reported production reflects production from Costerfield and Björkdal only from that date. See ALK announcement dated 9 Sep 2025 and titled ‘Alkane Announces Financial Year 2026 Guidance’. 3.

The Mineral Resource is estimated as at 31 Dec 2024 with depletion through to 30 June 2025. 2. The Mineral Resource is stated according to JORC (2012) and is wholly inclusive of Ore Reserves. 3. Tonnes are rounded to the nearest thousand; contained gold (oz) is rounded to the nearest thousand; contained antimony (t) is rounded to nearest hundred. 4. Totals may appear different from the sum of their components due to rounding. 5. 4.3 g/t AuEq cut-off grade over a minimum mining width of 1.2 m is applied where AuEq is calculated using the formula: AuEq = Au g/t + 2.39 × Sb %. 6. The AuEq factor of 2.39 is calculated at a gold price of US$2,500/oz, an antimony price of US$19,000/t, and recoveries of 91% Au and 92% Sb. The recoveries of antimony and gold used in the calculation of gold equivalents are based on recent performance of the ores through the Costerfield processing facility. Alkane considers the elements included in the metal equivalents calculation have a reasonable potential to be recovered and sold. 7. Veins were diluted to a minimum mining width of 1.2 m before applying the cut-off grade, and peripheral mineralisation far from current development was excluded to comply with reasonable prospects for eventual economic extraction (RPEEE) criteria. 8. The stockpile Mineral Resource is estimated based upon surveyed volumes supplemented by production data. Reserves 1. The Ore Reserve is estimated as at 31 De 2024 and then depleted for production through to 30 June 2025. 2. Tonnes are rounded to the nearest thousand; contained gold (oz) is rounded to the nearest thousand; contained antimony (t) is rounded to nearest hundred. 3. Totals may appear different from the sum of their components due to rounding. 4. Lodes have been diluted to a minimum mining width of 1.5 m for stoping and 2.0 m for ore development. Unplanned dilution values are added to this with zero grade for Au and Sb for final grades. 5. A sustaining cut-off grade of 5.6 g/t AuEq is applied. An incremental cut-off grade of 3.2 g/t AuEq is applied where mining rates do not meet mill capacity and the life of the mine is not extended. 6. Commodity prices applied are a gold price of US$2,100/oz, antimony price of US$16,000/t and exchange rate US$:A$ of 0.68. 7. AuEq is calculated using the formula: AuEq = Au g/t + (1.55 × Sb %). 8. The Ore Reserve is a subset, a Proved and Probable only schedule, of a LOM plan that includes mining of Measured, Indicated and Inferred Resources. 1.

Norrberget Mineral Reserves are based on a data cut-off date of 30 Sep 2024. 3. Open Pit Mineral Reserves for Björkdal are based on mine designs carried out on an updated resource model, applying a block dilution of 100% at 0.0 g/t Au for blocks above 1.0 g/t Au and 100% at in situ grade for blocks below 1.0 g/t Au but above a cut-off grade of 0.2 g/t Au. The application of these block dilution factors is based on historical reconciliation data from 2018 and 2019. A marginal cut-off grade of 0.2 g/t Au was applied to estimate open-pit Mineral Reserves. 4. Open Pit Mineral Reserves for Norrberget are based on 25% dilution at 0.0 g/t Au and a cut-off grade of 0.32 g/t Au. 5. Underground Mineral Reserves are based on mine designs carried out on the updated resource model. Minimum mining widths of 3.1 m for stopes (after dilution) and 4.6 m for development (after dilution) were used. Stope dilution was applied by adding 0.25 m on each side of stopes as well as an additional 25% sidewall over break dilution. Dilution factors of 20% for ore drives and 10% for capital development were applied to the development design widths. Mining extraction was assessed at 95% for contained ounces within stopes and 100% for development. A cut-off grade of 0.85 g/t Au was applied to material mined within stopes. An incremental cut-off grade of 0.2 g/t Au was used for development material. 6. Stockpile Mineral Reserves are based upon surveyed volumes supplemented by production data as of 30 June 2025. 7. Mineral Reserves are estimated using an average long-term gold price of US$2,100/oz for Björkdal and Norrberget, and an exchange rate of 10.35 SEK/US$. 8.
