Non-IFRS Performance Measures

This announcement contains references to all-in sustaining costs which is a non-IFRS measure and does not have a standardised meaning under IFRS. Therefore, this measure may not be comparable to similar measures presented by other companies. All-in sustaining costs include total cash operating costs, sustaining mining capital, royalty expense and accretion of reclamation provision. Sustaining capital reflects the capital required to maintain a site’s current level of operations. All-in sustaining cost per ounce of gold equivalent in a period equals the all-in sustaining cost divided by the equivalent gold ounces produced in the period.

¹ Gold equivalent ounces calculated by multiplying quantities of gold and antimony in period by respective average market price of commodities in period, 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 period. 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 US$3,457/oz Au (being the average of the daily PM price, sourced from ) and US$21,928/t Sb (being the average Shanghai Metal Market Price sourced from []). The average market prices for the statutory reporting period were US$3,521/oz Au (being the average of the daily PM price, sourced from ) and US$22,151/t Sb (being the average Shanghai Metal Market Price sourced from ).

² Group Production on basis of 100% contribution from Tomingley, Costerfield and Björkdal for the quarter. As 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. Refer to ALK announcement dated 9 September 2025 titled ‘Alkane Announces Financial Year 2006 Guidance’.

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.
