KEY ACTIVITIES

Kimberley Mineral Sands Pty Ltd (KMS) (Sheffield interest 50%)[1]

Following an injury occurring during the quarter, the Thunderbird Mineral Sands Mine (Thunderbird) restricted injury frequency rate increased from 0.0 to 1.32 as at the end of June quarter.

Thunderbird mined 2.9Mt of ore and achieved record quarterly concentrate production of 201,234 dry metric tonnes. Improvements in equipment availability has seen productivity from the Dry Mining Unit (DMU) increase considerably throughout the quarter. Contracted waste mining activities were successfully transitioned to the new contractor utilising larger equipment during the June quarter.

For the June quarter, the Heavy Mineral (HM) grade of the feed to the process plant (Rougher Head Feed or RHF) was 18.8%, comparable to the 18.9% achieved during the previous quarter. With the increase in mining rate, Rougher Head Feed volumes achieved have increased from 75% to approximately 80% of basis of design per tonne of ore mined, demonstrating that the planned increase in mining rate by Q1 FY27 should ultimately offset the RHF constraint. The process plant continues to perform strongly, with TiO2 and ZrO2 recovery continuing above basis of design.

Thunderbird product shipments for the quarter totalled 200,120 metric tonnes including 39,123 tonnes of zircon concentrate. A further 37,800 metric tonnes of concentrate was shipped in early July, following a crane mechanical failure resulting in a temporary suspension of operations at the Port of Broome from late June to early July.

Mine Operating Performance

Mine production was 2.9Mt ore mined in the June quarter. Figure 2 below illustrates mine production for the quarter, compared to the previous quarter and for the same quarterly period in 2024. Ore production for the month of June exceeded 1Mt and it is expected that optimised waste clearing activities that commenced during the June quarter shall drive improved mining rates in FY2026.

Sales

The Kimberley Port Authority experienced a crane equipment failure at the Port of Broome in late June 2025, resulting in a temporary suspension of loading operations. Consequently, sales of Thunderbird product were impacted, with the deferral of approximately 37,800 tonnes of concentrate shipments, including 9,900 tonnes of zircon concentrate, originally scheduled for shipment at the end of the June 2025 quarter.

Quarterly product shipments of ilmenite concentrate totalled 160,997 metric tonnes under the offtake agreement to joint venture partner, Yansteel. Product pricing is fixed price per percent of TiO2 content contained within the ilmenite concentrate, with realised pricing of approximately US$131/t for the quarter reflecting higher TiO2 content than the 38.5% assumed in the contract value of US$123/t.

Zircon concentrate shipments for the quarter totaled 39,123 metric tonnes, within the range of guidance previously estimated. The average realised price achieved for zircon concentrate was US$565/t for the quarter, with the $20/t increase on the March quarter primarily the result of variations in the mineral content of the concentrate.

Financial

C1 cash costs per tonne produced (excluding inventory movement) were $347/tonne of concentrate for the June quarter, compared to $328/tonne of concentrate for the previous quarter. Increased waste mining costs were the primary driver for the higher quarterly incurred costs, driven by the mobilisation of newly appointed waste mining contractors, along with a significant increase in waste stripping and clearing achieved for the quarter, approximately 60% above the consecutive quarterly average waste movement for the financial year to the end of March 2025.

Underlying C1 cash costs was $340/tonne of concentrate, compared with $512/tonne for the previous quarter. Finished goods inventory comprises approximately 70,000 tonnes of ilmenite concentrate and over 25,000 tonnes of zircon concentrate available for shipment as at the end of the quarter.

Operating cashflows totalled $25m for the quarter. The June quarter included the payment of interest to senior secured lenders, alongside a US$11m scheduled principal repayment to Orion Resource Partners. During the quarter, discussions commenced with Orion and NAIF on resculpting and aligning the scheduled debt repayments to the revised mine plan, costs and forecast prices.

Furthermore, repayment of offtake prepayment facilities to Yansteel for the quarter totalled $12m (US$8m) and new prepayments for ilmenite totalling $31m were drawdown, assisting with short term working capital requirements.
