That balance sheet strength gives us the flexibility to keep investing in our growth pipeline while continuing returns to shareholders as reflected in the Board’s decision to upsize our buyback to $150m this quarter. I want to thank our employees and contractors across all our operations and projects for their dedication and hard work over the past year — the milestones we've delivered are a direct reflection of their commitment.

Looking ahead, FY27 will be a transformational year for Perseus as we bring two major growth projects — CMA Underground and Nyanzaga — through to commercial production alongside our existing operations”.
