Nordic Resources (ASX:NNL) Executive Director Robert Wrixon on new higher grade gold copper zone at Kopsa

Nordic Resources Executive Director Robert Wrixon addresses the latest drilling results from the Kopsa gold copper project in Finland, where step out drilling has intersected a previously unknown higher grade, stockwork-style gold zone along the northern tonalite footwall contact, far outside the current Mineral Resource Estimate, with results supported by coincident borehole electromagnetic conductors and broad mineralised widths that extend the known system beyond its existing boundaries.

What is the geological and economic significance of the new higher grade zone intersected in hole NRKOP25012B relative to the existing Kopsa Mineral Resource Estimate?

Hole NRKOP25012B intersected 16.9m @ 2.71g/t Au and 0.12% Cu for 2.84g/t AuEq from 216.1m, within a broader interval of 63.0m @ 0.94g/t Au and 0.15% Cu for 1.11g/t AuEq from 178.0m, with a further shallower intersection of 16.8m @ 1.05g/t Au and 0.14% Cu for 1.21g/t AuEq from 79.0m, with the main intersection located more than 100m from the nearest existing resource block and all entirely outside the current Mineral Resource Estimate.

The mineralisation is developed at the northern tonalite footwall contact and displays stockwork characteristics that are directly comparable to those observed in the Central Zone, which hosts the highest grades in the current resource, marking the first time that this style and width of higher grade mineralisation has been intersected beyond that core area.

“The stockwork style higher grade gold copper mineralisation encountered over 16.9m in NRKOP25012B is similar in nature to the Central Zone but occurs outside the current resource and at the tonalite footwall contact, confirming that this structural position hosts higher grade material over significant widths.”

The coincidence of this intersection with a borehole electromagnetic conductor plate further supports the interpretation that the footwall contact may represent a key control on mineralisation and that continuity may extend beyond the current drilling, both laterally and at depth.

How do the northern step out drill results alter the potential scale and continuity of mineralisation at Kopsa?

The three newly collared holes in the northern zone, NRKOP25012B, NRKOP25014 and NRKOP25016, all intersected gold copper mineralisation outside the existing JORC 2012 resource envelope, demonstrating that the Kopsa system extends beyond its previously defined northern limits and into areas that had not been drill tested.

NRKOP25014 returned 56.2m @ 0.48g/t Au and 0.20% Cu for 0.70g/t AuEq from 119.5m at the footwall contact, while NRKOP25016 intersected near surface mineralisation of 6.2m @ 1.35g/t Au and 0.22% Cu for 1.59g/t AuEq from 13.3m, confirming that mineralisation is present from shallow levels down to the deeper contact zone.

“All three new holes intersected significant gold copper mineralisation well outside the existing resource boundary, confirming that the northern footwall contact is mineralised over substantial widths and remains open along strike and at depth.”

When considered together, these results indicate that the tonalite contact zone hosts a significant mineralised system beyond the current Minerals Resource Estimate (MRE), supported by consistent geological and geophysical vectors.

What implications do the new intersections have for future resource updates and classification?

Kopsa currently hosts a JORC 2012 compliant Mineral Resource of 23.2Mt @ 1.09g/t AuEq for 814,800oz AuEq, while the combined Middle Ostrobothnia Gold Belt inventory stands at 34.3Mt @ 1.11g/t AuEq for 1.23Moz AuEq, with 66% classified as Measured and Indicated.

The higher grade and broad intercepts in the northern zone, including the 63.0m @ 1.11g/t AuEq and the contained 16.9m @ 2.84g/t AuEq in NRKOP25012B, lie entirely outside the current resource wireframes and therefore represent mineralised volumes that are not yet reflected in the existing estimate.

“The higher grade footwall contact zone in the northern area sits outside the current Mineral Resource Estimate and provides clear potential for inclusion in future resource updates, subject to additional drilling to define continuity and geometry.”

These data, together with the remaining 2025 drill results and updated metallurgical parameters, will form part of the planned 2026 resource update.

How does the application of borehole electromagnetics influence targeting and confidence in depth continuity?

The higher grade intersection in NRKOP25012B coincides with a borehole electromagnetic conductor plate identified in earlier surveys, which is interpreted to align with the northern tonalite footwall contact and to be associated with sulphide bearing gold copper mineralisation.

This spatial relationship provides an independent geophysical vector supporting the geological interpretation of the contact as a preferred locus for accumulation of higher grade mineralisation and indicates that the conductive system may continue beyond the current depth of drilling.

“The coincidence of higher grade mineralisation with the borehole electromagnetic conductor suggests that the contact zone has potential depth continuity and validates BHEM as a targeting tool for follow up drilling at Kopsa.”

The successful intersection at the predicted location strengthens confidence in using electromagnetic responses to guide deeper and step out drilling.

What is the current funding position and forward drilling strategy following these results?

As at the end of December 2025, Nordic Resources reported cash of over A$12M, providing funding capacity to progress further drilling and evaluation work at Kopsa and across the Middle Ostrobothnia Gold Belt.

Assays from the remaining 10 holes of the 2025 drilling program at the 815koz AuEq Kopsa deposit are pending, and the next phase of diamond drilling is scheduled for March to April, with a focus on further step out drilling along the northern footwall contact, continued step put drilling to the southwest and follow up of borehole electromagnetic conductors, and continued testing around the existing resource envelope.

“With more than A$12M at bank and additional assay results pending, the planned March to April drilling program is designed to further test depth and strike extensions of the northern footwall zone and to support the next iteration of the Kopsa Mineral Resource.”

Northern footwall zone emerges as a new growth front at Kopsa

The confirmation by Nordic Resources of higher grade stockwork style gold copper mineralisation along the northern tonalite footwall contact, outside the current resource envelope and supported by multiple step out intersections and coincident borehole electromagnetic conductors, establishes this structural corridor as a priority target for further drilling.

With additional assay results pending, a well-funded balance sheet and a scheduled March to April drill program, the Kopsa project is positioned for continued resource growth and refinement ahead of the next planned Mineral Resource Estimate update.
