Latitude 66 Confirms 2.5km Gold-Cobalt Trend with Cost-Effective RC Drilling

Successful RC Drilling Validates K6 Prospect Potential

Latitude 66 Limited (ASX, LAT) has reported encouraging results from its first reverse circulation (RC) drilling campaign at the K6 Prospect, part of the broader KSB Project in northern Finland. The program, comprising 12 vertical holes totaling 315 metres, successfully confirmed the extension of a gold and cobalt mineralised trend stretching approximately 2.5 kilometres from the established K1 deposit. This continuity reinforces the prospectivity of the KSB North Project area and highlights the potential for resource growth.

The drilling intersected zones of anomalous gold, cobalt, and copper mineralisation, accompanied by albite alteration, which collectively suggest the drill holes encountered the margins of a mineralised system. Notably, the mineralisation appears to represent a distal or peripheral expression of a more robust, deeper mineralised core yet to be tested. This interpretation is supported by adjacent geochemical anomalies, including high-grade surface boulder samples and base-of-till assays, indicating that higher-grade mineralisation may lie nearby.

RC Drilling, A Game-Changer for Finnish Exploration

Beyond the geological findings, the program demonstrated the viability of RC drilling as a lower-cost, higher-productivity alternative to traditional diamond core drilling in the Finnish environment. While RC drilling is uncommon in European terrains, Latitude 66’s trial showed it can achieve significantly faster drilling rates at roughly half the cost, making it an attractive method for rapid first-pass exploration. This efficiency could accelerate the testing of numerous targets across the KSB Project, enabling more agile and cost-effective exploration campaigns.

Latitude 66 is actively engaging with European partners to further develop RC drilling capabilities tailored to local conditions, including potential funding arrangements to expand rig operations. This strategic move could position the company at the forefront of exploration innovation in the region.

Structural and Geochemical Insights Point to Deeper Targets

Detailed analysis of the K6E and K6W prospects revealed structural features consistent with those controlling mineralisation at nearby deposits K1, K2, and K3. In particular, a fold hinge associated with a strong induced polarisation chargeability anomaly was identified at K6E, suggesting a structural trap favourable for sulphide accumulation. Elevated cobalt results at lithological contacts further underscore the prospect’s complexity and potential.

Latitude 66 plans to integrate these drilling results with ongoing geological, geochemical, and geophysical datasets to refine targeting. Future work will focus on detailed mapping, reprocessing of geophysical data, and multi-element geochemical reviews to vector towards the mineralisation core. These efforts aim to delineate deeper or structurally controlled mineralisation zones that could significantly enhance the project’s resource base.

Outlook and Next Steps

With the maiden RC drilling program successfully validating both the geological model and the drilling methodology, Latitude 66 is well positioned to accelerate exploration at K6 and across the KSB Project. The company’s Managing Director, Grant Coyle, emphasised the importance of these results in guiding future work and improving exploration efficiency.

Upcoming phases will likely include step-out drilling to test the high-grade cores suggested by geochemical anomalies, alongside continued structural and geophysical studies. The integration of these datasets will be critical to unlocking the full mineral potential of the K6 corridor and advancing the KSB Project towards resource expansion.
