Alkane Resources (ASX:ALK) has updated the mineral resource estimate (MRE) for its Storheden deposit in Sweden, delivering a 26% increase in contained gold.
The deposit, located 700m north of the Björkdal mine, now holds indicated resources of 1.07 million tonnes (Mt) grading 2.51 grams per tonne (g/t) gold (Au) for 87,000oz, alongside inferred resources of 1.85Mt @ 2.11g/t Au for 125,000oz.
This compares to the previous inferred resource of 1.77Mt @ 1.74g/t Au for 99,000oz.
Recent drilling has extended Storheden’s footprint to more than 2.7km in strike length and 464m in depth, with mineralisation remaining open in all directions.
Alkane completed 16 extensional diamond drill holes for 7,965m between January and March 2026.
Notable intercepts include 0.4m @ 107.0g/t Au, as well as 0.95m @ 50.9g/t Au and 0.6m @ 39.2g/t Au.
Managing Director Nic Earner says Storheden represents an exciting growth prospect for the broader operation.
“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,” Earner says.
“Additionally, portions of the mineral resource have now been drilled to a density sufficient to estimate indicated resource.”
The company is planning an initial 10,000m surface drilling program in the 2027 financial year, with construction of an underground exploration drive scheduled to commence in September 2026 to support infill drilling and future production.
Alkane Resources is a gold and antimony producer with three operating mines across Australia and Sweden.
