Simon Tyrrell, Chief Operating Officer, Greatland Resources Limited: Thanks, Shaun. Thanks for the question, Daniel. As you’ve noted, exceptional achievement by the team, best quarterly results since 2010. This was due to that focus on the pyrite circuit and leaching circuit at the back of the plant. This was often overlooked as an area that didn’t contribute significantly to recovery. The background knowledge that the team we’ve brought on had with the original feasibility study has allowed us to unlock these higher recoveries. There was a point where we thought as we progressed through the new stage seven cutback that ore from the oxide and transitional part of the pit may cause us some lower recoveries. However, at the current blend rates, which is around 15% of stage seven material in the overall blend, that’s not causing us any concerns. We expect to achieve those mid-80s or above moving forward for FY2026.
When we go into FY2027, we do move to 40% of stage seven as a blend. We will need to do a bit more work to see whether we can maintain those into FY2027, but certainly FY2026, as noted, we’re comfortable getting that mid-80s or above.
From what Simon said they are using 15% of Stage 7 ore using the PIL circuit and still getting over 80% recovery rates. From next June they’re hoping to use 40% ore from Stage 7
As it goes deeper the ore turns to sulphides and can be put through the copper flotation circuit.
