Nordic Resources (ASX:NNL) has reported new drill results extending gold-copper mineralisation well beyond the 2025 resource boundary at its Kopsa project in Finland, supporting an upcoming resource upgrade.
- Three step-out holes confirm mineralisation 50-100m beyond current resource
- Significant intersections include 58m at 0.61g/t Au and 0.18% Cu
- Kopsa resource currently 814,800oz AuEq at 1.09g/t
- Updated resource statement planned for Q3 2026
- Company holds over A$10M cash, drilling to continue late 2026
Step-Out Drilling Confirms Kopsa Resource Growth Potential
Nordic Resources (ASX:NNL) has extended the known gold-copper mineralisation at its Kopsa project in central Finland with new assay results from three step-out diamond drill holes. These latest holes, drilled in the southeastern zone, intersected wide zones of mineralisation well beyond the 2025 resource boundary, confirming continuity along strike and at depth.
The standout intersections include 58 metres at 0.61 grams per tonne (g/t) gold and 0.18% copper from 353 metres, and 69 metres at 0.53 g/t gold and 0.12% copper from 321 metres. Narrower high-grade intervals within these broader zones reached up to 3.58 g/t gold and 0.77% copper, underscoring the deposit’s grade variability.
Resource Boundary Extended by 50-100 Metres
All three holes were drilled at least 90 metres beyond the previous 2025 drill holes in the southeast, pushing the known mineralised lodes 50 to 100 metres outside the current resource block model. The results also demonstrate significant depth continuity within the host tonalite intrusion, a key geological feature of the deposit.
This expansion is particularly notable given Kopsa’s existing JORC-compliant resource of 23.2 million tonnes at 1.09 g/t gold equivalent (AuEq), containing approximately 815,000 ounces of gold equivalent. Kopsa forms the core of Nordic’s Middle Ostrobothnia Gold Belt (MOGB) portfolio, which collectively holds 34.3 million tonnes at 1.11 g/t AuEq for 1.23 million ounces AuEq across three projects.
Resource Update and Drilling Program Timeline
The company intends to compile these new results, along with pending assays from additional holes drilled in the northern and southwestern zones, into an updated resource statement by the end of Q3 2026. Metallurgical test work results are also expected by late July, which will feed into the resource update and potentially refine the gold-copper equivalence calculations.
Nordic remains well-capitalised with over A$10 million in cash as of March 2026, supporting ongoing exploration. Drilling is set to resume in late July with two rigs booked through the end of the year, aiming to further define and expand the Kopsa resource and other MOGB assets.
Geological Context and Technical Confidence
The Kopsa mineralisation is hosted within a tonalite intrusion and surrounding metasedimentary rocks, characterised by disseminated and veinlet sulphides including chalcopyrite and arsenopyrite with fine-grained native gold. Drill orientations have been carefully designed to intersect the mineralised lodes near-perpendicularly, supporting reliable grade and thickness estimates.
True thicknesses of mineralisation are estimated at 70-80% of downhole widths, a standard adjustment given the drilling angles. Assay quality control protocols and independent verification underpin the confidence in these results, which are expected to enhance the resource’s size and classification.
Bottom Line?
Kopsa’s southeast extensions bolster Nordic Resources’ resource growth narrative, but upcoming assay results and regulatory clarity will be critical to fully gauge project momentum.
Questions in the middle?
- How will the pending assays from northern and southwestern holes influence the overall resource update?
- What impact might the ongoing appeals on mining permits have on project development timelines?
- Could metallurgical test results materially alter gold-copper recoveries and economic assumptions?
