Slide 15: District-Scale Exploration Thesis
District-Scale Exploration Thesis Multiple mineralized centres surrounding Star Main • Star Main: established porphyry copper- gold system with a preserved supergene cap and broad hypogene mineralization. • Copper Creek: first modern hole confirmed 111 m of copper-gold mineralization; 2026 follow-up
Slide 16: Copper Creek Target
Copper Creek Target Modern drilling confirms copper-gold mineralization • CC-25-001 was the first modern drill test since 1970s work and confirmed broad structurally controlled copper-gold mineralization. • Mineralization is associated with shearing, brecciation and quartz-epidote-sulphide veining,
Slide 17: Star North Target
Star North Target From first drill test to 2026 follow-up • Located approximately 1 km northeast of Star Main and defined by a large Cu-Au-in-soil anomaly coincident with strong IP chargeability. • 2025 mapping and 119 rock samples included semi-massive chalcopyrite grab samples reported at 17.6% Cu
