Highlights

• Highly successful geophysics campaign has generated multiple high-priority targets, including extensions to known prospects and new near surface and at depth anomalies, noting that the MMT survey covered only ~34% of the overall 402 km² tenement package.
• The combined area of the new targets is 10 times larger (by surface extrapolation) than the area of the existing 55Mt Mineral Resource Estimate ("MRE") at Dingelvik.
• Integration of MMT and MVI data has delivered high confidence targeting.
• Next steps include ground validation, followed by target ranking and prioritisation for drill testing. Further MMT surveys are planned for 2026.

The seven high-priority targets identified include:

• Henneviken - Asslebyn: A continuous shallow magnetic high and conductive trend links Henneviken to Asslebyn, suggesting a southern and depth extension of the copper ("Cu") bearing horizon beyond the mineralisation intersected by historic drilling.
• Henneviken East (North & South): A newly detected and untested ~6km NW-SE magnetic corridor located ~2km east of Henneviken follows mapped faults that may have controlled Cu mineralisation. The southern end overlaps a strong MMT conductor, forming a coincident magnetic-conductive zone. A separate and untested conductive anomaly appears to trace a fold in the Cu bearing horizon.
• Baldersnäs: A strong conductive trend (MMT) NE of Dingelvik aligns with the edge of the original Baldersnäs prospect, the Dingelvik MRE, and a mapped NW-SE fault which coincides with shallow magnetic highs larger than those seen within the current Dingelvik footprint.
• Dingelvik South: A newly detected, large, deep magnetic feature with feeder-like structures, a potential source zone for the Dingelvik MRE.
• Ravarp: A newly detected target that hosts a deep magnetic high located at the apex of a folded magnetic belt adjacent to the Cu bearing horizon. This feature forms part of a broader north-trending magnetic-high corridor that mirrors the orientation of the Cu bearing horizon within favourable host rocks.
• Stora Strand: A NW-SE conductive corridor intersects a deep magnetic high that rises toward surface, creating a clear overlap of conductivity and magnetics which aligns with the historic Stora Stand Cu mine.
• Dingelvik MRE Extension: Magnetic and conductivity anomalies representing potential extensions to the known MRE.

Director Peter George commented:

Very exciting times for the Hennes Bay Project. On the back of the maiden 55Mt MRE released in March 2025 and the positive underground conceptual study in September 2025, this geophysical data modelling has again highlighted the massive upside potential at our flagship project.

Completing the MMT survey and MVI modelling across a portion of Hennes Bay represents a major step forward for our exploration program. The integrated datasets, highlighting clear overlaps between conductivity and magnetic features that coincide with known mineralisation have provided a "Proof of Concept" for the effectiveness of these methods, and importantly have also defined multiple new high-priority targets.

This is a major development, and it is even more impressive when you consider that we have only surveyed a third of the overall tenement package area. Accordingly, we believe that there are a lot more high-priority targets to uncover.

We will now move quickly on to ground validation and finalising the ranking and prioritisation of the targets for drill testing, with the aim of delivering resource growth and new discoveries.
