District Metals has outlined additional uranium-bearing zones at its wholly owned Sågtjärn property in Sweden, where reconnaissance work has also detected molybdenum, cobalt and copper mineralisation. The results extend exploration targets beyond historically investigated areas and come as Sweden reopens its uranium sector following years of restrictions.
The Canadian exploration company that uranium-bearing formations had been identified over approximately two kilometres, with selected rock samples returning up to 3,656 parts per million U₃O₈.
The programme also recorded molybdenum concentrations of up to 5,250 ppm, while individual samples contained as much as 333 ppm cobalt and 1,800 ppm copper. The findings point to a broader polymetallic system, although the extent and economic significance of the additional mineralisation have not been established.
Surface Sampling Identifies Mineralisation Beyond Historical Areas
The exploration campaign covered the property in Jämtland and Västernorrland counties, following airborne radiometric and magnetic surveys completed in 2025. Geologists investigated 163 field stations and collected 32 rock samples from outcrops and mineralised boulders to examine geophysical anomalies and assess the continuity of known mineralisation.
Uranium was identified in pegmatite and granite intrusions, as well as in surrounding metamorphic gneiss formations. Uranium-bearing pegmatites were traced along approximately two kilometres of strike, extending northwest and southeast beyond the area previously drilled by the Geological Survey of Sweden.
Samples from the pegmatites returned up to 1,179 ppm U₃O₈, while mineralised gneiss boulders produced readings of up to 3,656 ppm U₃O₈.
Additional uranium-bearing boulders were located approximately 1–1.5 kilometres southeast of earlier exploration drilling around the Hammarmyran and Staverberget occurrences. These locations provide further targets for investigation and indicate that historical exploration may have covered only part of the mineralised system.
The results are based primarily on selected surface samples rather than new drilling. Consequently, the reported concentrations do not establish the thickness, continuity or economic viability of the underlying mineralisation. Drilling and further geological work will be needed to determine whether the targets represent extensions of known deposits or separate mineralised structures.
Historical Resource Provides a Geological Reference
The Geological Survey of Sweden discovered Sågtjärn in 1974 during geochemical exploration. Systematic sampling, geophysical investigations and diamond drilling followed during the late 1970s.
Historical assessments estimated approximately 756,000 tonnes grading 0.068% U₃O₈, equivalent to around 1.14 million pounds of uranium oxide.
District Metals classifies this figure as a historical estimate, not a current mineral resource compliant with Canada’s NI 43-101 disclosure standard. Verification through additional exploration, including drilling alongside historical boreholes, would be required before the estimate could be incorporated into a modern resource assessment.
The newly identified mineralisation could provide grounds for reassessing the property beyond its original resource area. However, establishing additional mineralised volumes and demonstrating suitable grades and technically feasible extraction methods will be necessary to determine whether the project’s resource potential has materially increased.
Molybdenum, cobalt and copper add further exploration targets, but their potential contribution to project economics remains unquantified. Any future polymetallic development would depend on defining the resources, establishing metallurgical recoveries and assessing the processing costs associated with the different mineral-bearing formations.
Sweden’s Reopened Uranium Sector Changes Regulatory Conditions
The exploration results coincide with Sweden’s policy shift on uranium extraction. The country lifted its uranium mining, reversing restrictions introduced in 2018 and allowing uranium exploration and mining applications to proceed under its mineral legislation.
Further legislative changes adopted in June addressed the regulatory treatment of uranium extraction and processing, providing a clearer framework for evaluating projects alongside other mining activities.
The policy reversal has renewed interest in Swedish uranium deposits as European governments examine nuclear fuel supply security and the resilience of critical-mineral supply chains. Sweden has an established nuclear electricity industry, although its domestic uranium deposits remain undeveloped.
Reopening the sector could provide exploration companies with opportunities to define new uranium resources within the European Union. However, domestic mine development would not by itself eliminate reliance on foreign uranium conversion, enrichment and fuel-fabrication services.
Environmental approvals remain an important part of project development. Uranium extraction requires assessment of groundwater protection, radioactive materials, mine waste, long-term rehabilitation and potential impacts on surrounding communities. Projects must still undergo technical evaluation, environmental assessment and the relevant permitting procedures before commercial production can be considered.
Sågtjärn Complements District Metals’ Viken Project
Sågtjärn is part of District Metals’ wider Swedish uranium and polymetallic exploration portfolio, which also includes the larger Viken project. A preliminary economic assessment published in July 2026 outlined a potential large-scale uranium and critical-metals operation at Viken, with estimated initial capital expenditure of approximately $876 million.
Sågtjärn remains at an earlier exploration stage and has different geological characteristics from Viken’s extensive alum-shale mineralisation. Its uranium occurrences in pegmatites and gneiss provide alternative geological targets that could require different mining and processing approaches.
Further work at Sågtjärn is expected to integrate the geochemical findings with the 2025 airborne geophysical surveys, refine priority drilling locations and test whether the surface discoveries correspond to continuous bedrock mineralisation.
Additional exploration will also need to establish whether the molybdenum, cobalt and copper occurrences represent recoverable concentrations or are secondary geological indicators. The latest findings have expanded the exploration targets but have not yet established a larger mineral resource or an economic development case.
