Alkane Resources Limited has reported high-grade gold and antimony intercepts from extension and infill drilling at the Brunswick South deposit, located 400m south of the previously mined Brunswick vein at its Costerfield Operation in central Victoria. The drilling program, comprising 91 holes totalling 28,421m, has confirmed grade continuity and identified a high-grade connection between the recently discovered gold-dominant zone at depth and historical surface workings.

Drilling Highlights

Significant intercepts from the Brunswick South vein include 109.9g/t gold and 3.1% antimony over 0.65m in hole BD433, and 50.1g/t gold and 26.2% antimony over 2.17m in hole BD468. Other notable results from the program include 50.2g/t gold and 33.3% antimony over 0.86m in BD424, and 39.8g/t gold and 0.7% antimony over 1.3m in BD408. The drilling has defined two main economic zones: an upper shoot of high-grade antimony-gold mineralisation and a lower panel of gold-dominated mineralisation with a strike length approaching 400m, known as the Kiwi Zone.

Future Plans

Alkane Managing Director & CEO, Nic Earner, stated that the newly defined deposit contains pockets of high gold endowment and a significant quantity of antimony. The company plans to commence development towards Brunswick South in the current quarter to establish it as a primary production source for Costerfield. An updated Mineral Resource Estimation with an initial Ore Reserve is scheduled for release later in the year. Additionally, follow-up drilling is planned for the Kiwi Fault structure and a parallel veining target identified approximately 200m to the west of Brunswick South.

Alkane Resources Limited has reported positive results from extension and infill drilling at the Björkdal Gold Mine in Sweden, including high-grade intercepts that extend known mineralisation to a depth of 762 m below surface. The drilling program, comprising 29 holes totaling 15,568 m, targeted the Eastern and Northern extensions of the underground mine. The results indicate the mineral system remains open at depth and along strike, supporting potential increases in production and mine life.

The Eastern Extension program delivered the deepest intercept recorded at the mine to date, with drillhole MU25-021 returning 3.5 g/t gold over 3.20 m at -976 RL (-762 m elevation). The program also yielded the best result from drillhole MU25-030, which returned 86.1 g/t gold over 1.25 m. Other significant results from the Eastern Extension included 81.3 g/t gold over 4.40 m in MU25-022 and 78.3 g/t gold over 0.30 m in MU26-005.

In the Northern Extension, drilling confirmed mineralised veins up to approximately 600 m from existing underground development. The best result from this area was 31.5 g/t gold over 0.85 m in drillhole MU26-002. Additional highlights included 25.2 g/t gold over 0.60 m in MU25-027 and 15.4 g/t gold over 4.00 m in MU25-032.

Alkane Managing Director & CEO, Nic Earner, stated that the positive results indicate the mineral system is still strong and open at depth. He noted that these results, together with the new resource at Storheden, support confidence in the potential to increase production and the longevity of the operation.

Northern Extension

The Björkdal Gold Mine is located on the eastern margin of the Skellefte Belt in northern Sweden. The operation became wholly owned by Alkane Resources following its merger with Mandalay Resources in August 2025. Since production began in 1988, the mine has produced approximately 1.69 million ounces of gold.
