Notably, the Phase VI extensional drilling showed multiple high-grade intersections. These were on the fringe of the current open pit design. Phase VII, according to BML, is set to follow up these intersections. The goal of the activity is to demonstrate continuity of mineralisation, alongside the possibility of incorporation into a revised pit design.
