Discussion of Results

The maiden drill program at Kouto intersected a highly strained volcano-sedimentary sequence comprising turbiditic greywacke, siltstone and mudstone, graphitic schists, and intermediate to mafic volcanic rocks. At this stage, gold mineralisation across the property displays a consistent style; however, two principal mineralised structural corridors have been defined (Figure 1).

The Eastern Structural Corridor

The eastern corridor is hosted within a 20 to 60 metre apparent thickness greywacke horizon intercalated within highly strained graphitic schists. Gold mineralisation is associated with quartz +/- carbonate veining containing arsenopyrite +/- pyrite +/- pyrrhotite, preferentially developed within silicified, sericite and chlorite altered greywacke (Figure 1). Significant intercepts include:

  • 27.0m at 4.16 g/t Au from 120.0m, including 12.0m at 8.14 g/t Au (KTORC25-055)
  • 38.0m at 0.94 g/t Au from 31.0m, including 19.0m at 1.31 g/t Au (KTORC25-056)

The Western Structural Corridor

The western corridor is spatially associated with a 15-kilometre faulted contact shale and mudstone and volcano sedimentary units. Mineralisation is mostly replacement and vein types with quartz +/- carbonate +/- arsenopyrite +/- pyrite +/- pyrrhotite veining developed within silicified, sericite and chlorite altered greywacke horizons (Figure 1). Significant intercepts include:

  • 8.0m at 2.49 g/t Au from 111.0m (KOTORC25-006)
  • 9.0m at 1.49 g/t Au from 112.0m (KOTORC25-003)
  • 9.0m at 1.06 g/t Au from 26.0m (KOTORC25-024)

Alex Ruggieri, CEO of Koulou, commented, “The 2025 to 2026 maiden drill results at Kouto confirm another grassroots discovery for our team. Anomalous BLEG results led to defining a 10 by 5 kilometre gold-in-soil anomaly which returned 27.0m at 4.16 g/t Au on the initial test, demonstrating the validity of our exploration model and the productivity of the Boundiali-Syama Greenstone Belt. With multiple high-priority targets at Kouto and across the broader portfolio, we are excited to generate additional value for our shareholders and host communities through systematic exploration and discovery.”

Project Portfolio Overview

Sakassou Project (396.9 km²)

Located within the Bouaflé Greenstone Belt, 35 km from Perseus Mining’s Yaouré Mine (3.58 Moz Au resources). Sakassou hosts multiple high‑priority targets, including the Bravo West discovery, where Koulou previously drilled 2.38 g/t Au over 33m (2021).

Kouto Project (298.5 km²)

Situated in the Boundiali–Syama Belt, adjacent to major deposits including Sissingué, Syama, Koné, and Aurum’s 3.03 Moz Au Boundiali resource. Koulou has made a grassroots discovery with intercepts including 27m at 4.16 g/t Au and 38m at 0.94 g/t Au.

Gontougo Project (1,021 km²)

Comprising the Assuefry and Koun‑Fao permits, Gontougo shares structural and geological characteristics with Endeavour’s Assafou discovery (4.6 Moz Au M&I). Previous work outlined a 15 by 3 kilometre gold-in-soil anomaly, representing a large-scale, untested target in a highly fertile geological setting.
