Edward Gosselin, CEO and Director of Kobo commented: “These latest results reinforce the scale and continuity of gold mineralisation at the Jagger Zone. We are encouraged by the width and tenor of the intercepts, which continue to validate our structural model and further support our systematic exploration approach at Kossou. With drilling still underway across our other high-priority targets, we are well-positioned to advance Kossou toward its maiden resource estimate next year as our exploration work continues.”

Jagger Zone Drilling Highlights Scale and Continuity

Results from seven diamond drill holes (KDD0080 to KDD0086), completed on sections JZ 525 to JZ 725 within the Jagger Zone, have been received and continue to expand the Company’s understanding of this highly prospective target (see Figure 1).

Gold mineralisation is hosted within and along the contacts of quartz feldspar porphyry and diorite intrusions, as well as within sheared contacts of basaltic massive and pillowed flow units. These structures define significant, laterally and vertically continuous gold-bearing zones that are traceable along strike and down dip. Notably, wide mineralised intervals in hole KDD0084, including 8.0 m at 1.41 g/t Au from 88.0 m and 21.5 m at 1.14 g/t Au* from 106.0 m (see Figure 2), demonstrate the presence of multiple stacked gold zones across the broader Jagger Shear Zone.

On section JZ 700, gold mineralisation continues to demonstrate strong continuity and consistent geological associations observed in earlier drilling. Notable intercepts include 20.0 m at 1.41 g/t Au* from 106.0 m, including 5.0 m at 3.70 g/t Au, and 7.0 m at 1.20 g/t Au from 154.0 m. These results support the broader interpretation of the Jagger Shear Zone as a robust, multi-zone gold system and correlate well with previously reported drill holes and surface trench KTR030a (see Figure 3 for Section JZ 700.)
