Nordic Resources has reported promising assay results from its latest drilling at the Kopsa gold-copper deposit in Finland, revealing significant extensions of gold mineralisation beyond the current resource boundary. These findings support ongoing resource growth and an expanded drilling program.
- Three new diamond drill holes extend gold-copper mineralisation west of Kopsa resource
- Hole NRKOP25009 delivers wider, higher-grade gold intervals than expected
- Shallow and deeper mineralised zones intersected outside existing resource model
- Resource inventory at Kopsa stands at 23.2Mt @ 1.09g/t AuEq for 815koz AuEq
- Drilling program expanded to 6,000m through December 2025 to test further extensions
Expanding the Kopsa Gold-Copper Footprint
Nordic Resources Ltd (ASX – NNL) has unveiled encouraging assay results from its ongoing diamond drilling campaign at the Kopsa gold-copper deposit in Finland’s Middle Ostrobothnia Gold Belt. The latest batch of three holes, totaling 549 meters, has successfully extended known gold mineralisation to the west of the current resource boundary, with one hole notably exceeding grade expectations in the shallow zone.
Hole NRKOP25009, drilled at the western edge of the existing resource, intersected 17 meters grading 1.32 grams per tonne gold and 0.10% copper, including a higher-grade 7-meter section at 2.35 g/t gold. A further 27-meter interval at 0.85 g/t gold was also recorded deeper down, both zones lying outside the current resource model. These results suggest the deposit’s footprint is broader and richer than previously understood.
Implications for Resource Growth and Drilling Strategy
All three holes encountered consistent lower-grade mineralisation associated with the tonalite shear zone at depths of 100 to 120 meters, again beyond the existing resource limits. This points to additional ounces of gold equivalent that could be added in the next resource update. The company has confirmed that these findings align with earlier drilling that showed extensions to the south and southwest, reinforcing the potential for further step-out drilling in multiple directions.
Currently, the Kopsa deposit hosts a JORC-compliant resource of 23.2 million tonnes at 1.09 g/t gold equivalent, equating to approximately 815,000 ounces of gold equivalent. This contributes to a broader portfolio of 1.23 million ounces AuEq across Nordic’s Middle Ostrobothnia Gold Belt projects. With 69% of Kopsa’s ounces classified in the Measured and Indicated categories, the deposit is well positioned for advancement.
Ongoing Drilling and Future Outlook
In response to these positive results, Nordic Resources plans to maintain its drilling rig at Kopsa through the end of December 2025 and expand the program to around 6,000 meters. Assay results from northern zone drilling are expected in the coming weeks, with the company committed to regular updates. A resource estimate incorporating the latest drilling and metallurgical data is anticipated in 2026, potentially reshaping the project’s valuation and development trajectory.
Executive Director Robert Wrixon highlighted the significance of the findings, noting the confirmation of gold-copper mineralisation extending further west and the strategic importance of ongoing step-out drilling to unlock additional resource growth.
Bottom Line?
Nordic Resources’ latest drilling success at Kopsa sets the stage for a resource upgrade and sustained exploration momentum into 2026.
Questions in the middle?
- How will the upcoming resource update reflect the new high-grade extensions at Kopsa?
- What impact might the ongoing appeals on mining permits have on project timelines?
- Could metallurgical test results influence future recovery rates and project economics?
