Latitude 66 Uncovers Expanded High-Priority Gold Targets in Finland

• FLEM surveys confirm and expand K1 conductor at KSB
• K1 conductor lies beyond current resource envelope
• Large-scale conductor identified at PSB’s Reutu Prospect
• Multiple drill-ready targets defined with drilling planned
• Pre-Feasibility Study and environmental work progressing

Geophysical Surveys Reveal Significant Extensions at KSB Project

Latitude 66 Limited (ASX:LAT) has unveiled compelling Fixed Loop Electromagnetic (FLEM) survey results that sharpen the focus on its Finnish gold-cobalt assets. At the KSB Project, the large-loop FLEM survey has not only confirmed the previously identified K1 conductor but has more than doubled its modelled conductance from 1,040 to 2,466 siemens. This suggests a substantially larger and potentially richer sulphide body than earlier understood.

The integrated FLEM and Downhole Electromagnetic (DHEM) modelling outlines a continuous conductor stretching approximately 320 metres along strike and plunging up to 650 metres down dip. Importantly, this conductor lies outside the current Mineral Resource envelope, which at KSB totals 7.2 million tonnes grading 2.7 g/t gold and 0.08% cobalt, equating to 650,000 ounces of gold and 5,840 tonnes of cobalt. Historical drilling around the conductor's margins, including a notable 5.6 metres at 7.3 g/t gold, bolsters the case for a mineralised sulphide target that could materially expand the resource.

New Large-Scale Targets at PSB’s Reutu Prospect

Meanwhile, at the PSB Project, FLEM surveys have defined a significant new conductor at the Reutu Prospect measuring roughly 1,200 by 700 metres. This large-scale anomaly lies sub-parallel to the Sihtunna Fault, a major regional structure considered a prime conduit for mineralising fluids. The conductor's scale and structural setting make it a highly attractive drill target, although electromagnetic data alone cannot yet distinguish between graphite and sulphide mineralisation.

The Reutu anomaly extends about 1.1 kilometres along strike and reaches depths of approximately 680 metres. Its smooth and continuous electromagnetic decay is consistent with a stratigraphic horizon that could host mineralised sulphides, supported by coincident magnetic highs. This discovery opens new avenues for exploration within Latitude 66’s Finnish portfolio.

Drilling and Development Plans Accelerate

With multiple high-priority targets now defined across both projects, Latitude 66 is moving quickly to capitalise on these findings. The company plans to commence a targeted diamond drilling program in the third quarter of 2026, focusing on the K1 resource extension at KSB and the newly identified conductors at PSB’s Reutu Prospect.

Simultaneously, Latitude 66 is advancing its Pre-Feasibility Study (PFS) for KSB, progressing mine design optimisation, geotechnical and hydrogeological studies, and environmental baseline assessments. Environmental Impact Assessment activities are ongoing to support future permitting, indicating a clear pathway toward project development.

Managing Director Grant Coyle emphasised the significance of the FLEM results, stating they provide compelling drill-ready targets that align with the company’s geological models and growth strategy. The scale of the PSB conductors, in particular, reinforces the potential for large-scale sulphide mineralisation analogous to other major northern Finland deposits.

Bottom Line?

Latitude 66’s expanded geophysical footprint in Finland sets the stage for a critical drill campaign that could reshape its resource profile and development trajectory.

Questions in the middle?

• Will drilling confirm the sulphide nature of the large PSB Reutu conductor?
• How materially could the K1 conductor extension increase the current resource estimate?
• What timelines will Latitude 66 set for updated resource statements post-drilling?
