Alkane Managing Director, Nic Earner, said:

“Alkane has had a solid quarter’s production from our three operating mines, which together produced 42,767 ounces of gold and 267 tonnes of antimony (43,663 ounces of gold equivalent) over the quarter.¹ Tomingley will pour its 750,000th ounce of gold during January 2026, a great testament to the team there. We have further strengthened our balance sheet over the quarter with A$246 million in cash, bullion and listed investments at quarter end.”

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 total contained value by 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). Average market prices for gold and antimony sourced respectively from LBMA daily PM price (www.lbma.org.uk) and Shanghai Metal Market Price (www.metal.com). Average market prices for December quarter were A$6,299/oz Au and A$30,245/t Sb and for September quarter were A$5,283/oz Au and A$33,508/t Sb using an AUD: USD exchange rate of 0.6565 and 0.6544 respectively.

² Group YTD Production calculated on basis of 100% contribution from Tomingley, Costerfield and Björkdal for relevant period. As the merger with Mandalay Resources completed on 5 August 2025, Alkane’s FY2026 statutory reported production will reflect 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 See ALK Announcement dated 9 Sep 2025 and titled ‘Alkane Announces Financial Year 2026 Guidance’ for calculation of Au Eq ounces and definition of Group Guidance. Production guidance on a statutory reported basis (‘Attributable Guidance’) is 155,000 – 168,000 AuEq ounces for FY2026.
