I am pleased however to confirm that we are still on track for June 2025 quarter production to be greater than the March 2025 quarter of 2,952 tonnes of copper produced. During the month, preparatory work was completed to allow the accelerated Nugent development to commence, this included independent firing and ventilation works. Going forward, we expect development will be greater than 700 metres per month across the deposits being mined.” April 2025 Monthly Production Kanmantoo Production Metrics Mining Summary Total Development Ore Mined In Situ Copper Mined Processing Summary Ore Processed Copper grade Processed Copper Recoveries Copper Produced Units April 2025 Month Mar 2025 Qtr Monthly Average m kt tonnes 574 100 802 606 113 1,076 kt % % tonnes 106 0.81 94.8 811 105 0.99 94.2 984 Authorised for release by the Board of Hillgrove Resources Limited.
