Appendix

Q1 2024 summary
Ramp up continuing – improvements in both mining and processing

Management Commentary

• Concentrate production of 20,692t at an average 5.0% Li2O grade with all products meeting customer specification
• Grants pit wall stability monitoring continues with a second radar installed
• Wet season preparedness is well-progressed and includes haul road upgrades and investment in water storage facilities and new dewatering equipment
• As of 31 October, there were 248,000t of ore on the ROM pad
• Recovery of 50% was achieved for the quarter compared to 49% previous quarter with adjustments to screen sizing, reagent set points and other process parameters
• Agreement finalised with one customer to allow acceptance of concentrate with a minimum grade of 4.5%. A similar agreement is being finalised with our second for the FY24 period.
• Test work and trials to improve plant recoveries continued as a priority

Quarterly Operating Performance

Finniss operational update

Costs are broadly in line, cash is impacted by shipment timing and QP adjustment

• C1 unit costs of $904/t were broadly in line with the previous quarter
• The build-up in ore on the ROM pad resulted in $985/t being deferred to inventory
• Before inventory movements, cash operating unit costs of $1,889/t were 11% higher than the previous quarter, due to a lower strip ratio, resulting in a higher proportion of the mining costs being expensed (rather than capitalised)
• Closing cash of $202.1 million included $107.9 million in proceeds from the equity raise and SPP in August
• The operating cash outflow of $25.97 million reflects:
  • the timing of shipments, with 8,527t of concentrate at the Darwin port on 30 September, which was included in the early October shipment; and
  • the repayment of $27.7 million to Yahua, in respect of a QP adjustment. The QP adjustment resulted from the significant fall in the lithium spodumene price between the date of prepayment and the end of the quotation period.
• Excluded from the cashflows in the quarter are the cash receipts relating to the 13,100t shipment in July. These tonnes were part of the prepayment arrangement with Yahua with the cash received in Q4FY23.
