Alkane is pleased to announce the latest exploration results and an updated Mineral Resource for the Storheden Deposit at its Björkdal Operation in northern Sweden.
Program Summary
- The Storheden Deposit is located approximately 700m north of the Björkdal mine, with recent drilling intercepting gold-bearing Quartz veins along 2.7km strike length and to a depth of 464m. The mineralisation remains open in all directions.
- 16 extensional diamond drill holes were completed at Storheden during January-March 2026, intercepting high-grade mineralisation within target zones defined through previous drilling campaigns.
- The recent drilling has contributed to an improved understanding of the lithostructural controls on gold-bearing Quartz veins, defining units that form targets for follow-up drilling.
- New modeling at Storheden including drilling over 2025 and 2026 has improved confidence, with inclusion of Indicated Resources, higher grade and significantly higher contained gold ounces.
- Indicated Resources 1.07 Mt grading 2.51 g/t Au (87 koz) and;
- Inferred Resources 1.85 Mt grading 2.11 g/t Au (125 koz)
- Details to follow in the annual NI43-101 Björkdal Technical document in September 2026
Assay Highlights from the Storheden Resource Growth campaign
- 36.1 g/t gold over 0.5m (ETW 0.35m) in SH26-004
- 50.9 g/t gold over 0.95m (ETW 0.82m) and
- 39.2 g/t gold over 0.6m (ETW 0.46m) in SH26-010
- 107.0 g/t gold over 0.4m (ETW 0.35m) in SH26-011
- 27.4 g/t gold over 0.7m (ETW 0.49m) in SH26-012
- Note: ETW refers to the Estimated True Width of the intercept. A full list of significant Storheden Intercepts can be found in Appendix 1 of the full announcement.
Alkane Managing Director & CEO, Nic Earner, said: “Storheden represents an exciting new growth prospect at Björkdal. The positive drilling results of this latest campaign begin to demonstrate the scale of the deposit, with the extent and depth continuity still unknown and open. Additionally, portions of the Mineral Resource have now been drilled to a density sufficient to estimate an Indicated Resource.
“Encouraged by continued positive results coupled with the potential Storheden provides, Alkane will continue to define the extents of the deposit and lift confidence in resources alongside the commencement of mine development to Storheden and the progression of permitting requirements for extraction.”
