Ann: Production Update, page-48

There is 3 aspects to the announcement.
1. The 94-hour shutdown was accelerated to enable replacement of components on the process plant’s grinding circuits following assessment by the operations team and risk mitigation strategy. The shutdown was successfully completed with replacement components performing as planned.
- This is likely to be hpgr related, items changed and back to business as usual
2. In addition, during the December quarter, production was negatively affected by lower than forecast crusher performance, which reduced plant throughputs and required feed of stockpiled crushed ore with higher quality variability.
- no mention of whether this has been rectified since.
3. Fines production through the flotation circuit also was interrupted by various initiatives that were trialled as part of Altura’s continuous improvement plan which is primarily aimed at increasing lithia recovery rates.
- This would involve trialling different float reagents to test for better recoveries in float cells. Nothing unusual
