Eneabba stockpile concentrate volumes vary for each blend. 1. Refer slide 9 and 22 for further information.2. Scenarios represent feed blends that may be used from time to time, in which case other feeds that are delivered but not included in the blend at a point in time, if any, would be stockpiled. The exclusion of third party sourced feedstocks in certain scenarios is not an indication of confidence in these sources; rather, it is intended to illustrate the impact of different blends on production outcomes.

Preferential distribution (royalty) payment to Iluka of up to $81 million p.a., capped at cumulative $900 million, accrues from July 2022, payable from project cash flows. Preferential cash flow mechanism reduces to as low as $40 million p.a. for first four years under low feedstock scenario of Eneabba stockpile only. Loan repayment obligations commence the earlier of Project Completion Date or December 2027 subject to cash flow availability. Interest capitalises during construction and commissioning. Interest is then payable quarterly unless there are insufficient funds and there are sufficient commitments for further capitalisation of interest. Facility loan amortisation schedule up to 16 years from Financial Close (December 2022) unless refinery feed sources are forecasted to deplete earlier. Based on Eneabba stockpile + Balranald, amortisation schedule ~8 years. Additional cash for distribution subject to minimum cash requirements and financial ratio tests.

Market development: first offtake secured, strategy aligned to megatrendsFirst rare earths offtake secured with global automotive company. Validates Iluka’s strategy to be part of the establishment of a new secure, credible supply chain for rare earths with prices independent of government backing.

Ex-China rare earths supply chain continues to expand in parallel with Eneabba rare earths refinery construction and commissioning Notes:1) Estimates for future total capacity based on relevant company announcements and consultants. Consultant estimates included are Adamas Intelligence and Project Blue. Announced projects have varying timeframes for completion.2) Estimates for NdPr oxide requirements based on estimates of 30t of NdPr metal required to produce 100t of NdFeB magnets and 1.2t of NdPr oxide to produce 1t of NdPr metal.
