Basin Energy Limited (ASX: BSN) has confirmed substantial uranium mineralisation across all three of its North Sweden Projects — Björkberget, Rävaberget and Virka — following modern re-assaying of historical diamond drill core.
The results validate and expand upon legacy data from the Swedish Geological Survey (SGU) and underscore the region’s uranium potential ahead of Sweden’s planned policy shift to lift its uranium exploration ban in January 2026.
The company said modern geochemical sampling and data validation across 59 historical drillholes confirmed extensive uranium intervals and the integrity of legacy datasets.
Mineralisation remains open along strike and at depth across all three project areas, strengthening confidence in the district’s broader exploration potential.
At the Björkberget Project, re-assays returned shear-hosted mineralisation including 12 metres at 0.12% U₃O₈ from 42.5 metres, with 4 metres at 0.23% U₃O₈ from 46 metres (BJK78002), and 2.5 metres at 0.27% U₃O₈ from 169.5 metres (BJK78001).
At Rävaberget, thick intervals included 14.4 metres at 0.15% U₃O₈ from 16.1 metres (RVB76003), with mineralisation remaining open at depth.
Basin has also staked 20 kilometres of prospective ground between Rävaberget and Björkberget, an area yet to be drilled.
The Virka Project recorded additional high-grade intersections, including 2.6 metres at 0.15% U₃O₈ from 27.8 metres (VIR80005) and 0.5 metres at 0.66% U₃O₈ from 26.3 metres (VIR80013), with mineralisation open along strike to the southwest and down dip.
“These results demonstrate the presence of an active mineralising system across three project areas, each capable of producing significant thickness and grades of uranium mineralisation,” said Basin Energy Managing Director Pete Moorhouse.
“The work completed in the 1970s and 80s was of good calibre; however, it was tightly focused on the limited areas of outcrop.”
Moorhouse said the strongest uranium intersections were recorded at Rava and Bjork, where Basin has secured an untested 20‑kilometre stretch of highly prospective ground between the two sites.
He said the company plans to leverage the new data and its in‑house uranium expertise to expand exploration along strike once Sweden’s policy changes take effect, positioning Basin to unlock the district’s full potential.
Moorhouse added that Basin’s early‑mover advantage places it at the forefront of a renewed European uranium and critical minerals sector, supporting the continent’s transition toward secure, low‑carbon energy supply chains.
Basin’s North Sweden Projects are located within the Fennoscandian Shield, a metallogenic province known for hosting volcanogenic massive sulphide (VMS) and orogenic gold deposits.
The company said the confirmed continuity of uranium mineralisation, combined with Sweden’s supportive policy trajectory and extensive infrastructure, positions it strongly within the emerging European uranium sector.
Basin plans to integrate the validated historical data into updated geological models ahead of 2026 field activities.
Subject to policy changes, the company intends to undertake mapping, sampling and airborne geophysical surveys during the next field season.
The results reinforce Basin Energy’s view that its North Sweden portfolio holds district-scale uranium potential in a Tier-1 jurisdiction, at a time when European nations are accelerating efforts to secure domestic sources of low-carbon energy metals.
