Ragnar Metals Uncovers Strong IOCG Signals in Southern Sweden Expansion

Strategic Expansion in a Promising IOCG District

Ragnar Metals Limited (ASX – RAG) has taken a decisive step forward in its exploration strategy by acquiring an additional 36 square kilometres of tenure in Southern Sweden. This expansion brings the company’s total landholding in the region to a substantial 159 km², positioning Ragnar as a key early mover in what it believes could be a new Iron Oxide Copper Gold (IOCG) district.

The company’s maiden reconnaissance rock sampling program across the expanded Olserum Project has delivered encouraging results. Notably, assays from the Domstugan and Tintorp prospects have returned significant copper and gold grades, alongside silver and molybdenum, hallmark indicators of IOCG-style mineralisation. These findings validate Ragnar’s strategic focus on this underexplored region.

Compelling Geological Context and Mineralisation

The geological framework underpinning Ragnar’s tenure is highly favourable. The region’s Palaeoproterozoic quartzites, intruded by granites associated with the Transscandinavian Igneous Belt, provide the ideal host rocks and structural controls for IOCG systems. Recent reinterpretations suggest that mineralisation at the historic Gladhammar copper-gold mine is linked to hypersaline hydrothermal fluids, consistent with IOCG deposit models rather than sedimentary origins previously assumed.

Field sampling revealed copper grades up to 2.2% and gold up to 1.2 grams per tonne, with associated magnetite and chalcopyrite mineralisation. The presence of circular magnetic features at Domstugan and Tintorp further supports the IOCG model, as these geophysical signatures are typical of such deposits globally.

Next Steps and Exploration Outlook

Building on these promising early results, Ragnar plans to prioritise detailed geological mapping and geophysical surveys, including magnetics, induced polarisation, and gravity methods, to refine subsurface targets. The company aims to delineate drill-ready targets within the Olserum North and Gladhammar South projects, leveraging the combined geological, geochemical, and geophysical data sets.

While the true width and economic viability of the mineralisation remain to be confirmed through drilling, Ragnar’s methodical approach and strategic land consolidation underscore its commitment to unlocking the potential of this emerging IOCG province in Southern Sweden.
