Bjorkdal Eastern Extension

Björkdal – Near Mine Exploration Update

Alkane is pleased to report further positive results from extension and infill drilling at the Björkdal Gold Mine in Sweden.

Program Summary

  • An additional 29 drill holes have been completed targeting the Eastern and Northern extensions of the Björkdal mine since Alkane’s previous release (ASX announcement 15 October 2025 titled ‘Björkdal Resources and Reserves Statement FY25’)
  • The new drilling, completed in rolling phases of extension and infill across both target areas, has significantly enhanced confidence in the understanding of vein geometry and grade-controlling structures.
  • Grade continuity within both areas has been supported by the drilling with high-grade intercepts within the eastern extension extending the known mineralisation to a depth of 762 m below surface which is the deepest yet recorded in the field.
  • Current and planned exploration drilling will continue to target along-strike and down-dip extensions of the known mineralisation, with the objective of further expanding mineral resources and supporting future mine-life growth.

Alkane Managing Director & CEO, Nic Earner, said: “We are encouraged by the results coming from our near mine extension programs at Björkdal. The positive results indicate that the mineral system is still strong and open at depth. These results, together with the new resource at Storheden, support our confidence in the potential to increase production in addition to the longevity of the operation.”
