Executive Chair, Mr Bruce Griffin said “Production from Thunderbird continues to achieve record growth and the entire team is delivering upon our strategy to realise full production from Thunderbird by Q1 FY27. Mineral sands market conditions, particularly for KMS zircon concentrate are challenging, and as we enter the December quarter, there are few signs of market conditions showing improvement, which is impacting KMS sales volumes.”

KEY ACTIVITIES
– Kimberley Mineral Sands Pty Ltd (KMS) (Sheffield interest 50%)[1]
The Thunderbird Mineral Sands Mine (Thunderbird) continues to maintain a strong focus on health and safety across its operations, maintaining a total recordable injury frequency rate of 2.7 as at the end of the September quarter.
Thunderbird mined 3.0Mt of ore during the September quarter and achieved another quarter of record quarterly concentrate production totalling 249,145 dry metric tonnes. Continued improvements in mining has been observed with increased productivity across drill & blast, waste mining and Dry Mining Unit (DMU) operations throughout the quarter.
The Heavy Mineral (HM) grade of the feed to the process plant (Rougher Head Feed or RHF) during the quarter was 23.3%, comparable to the 18.8% achieved during the previous quarter. Rougher Head Feed volumes achieved were approximately 75% of basis of design per tonne of ore mined during the quarter. Consistent process plant performance during the quarter saw TiO2 and ZrO2 recovery continuing above basis of design.
Thunderbird product shipments for the quarter totalled 216,919 metric tonnes including 38,946 tonnes of zircon concentrate. Product shipments were below forecast for the quarter, reflecting challenging market conditions in China for zircon concentrate.

Zircon concentrate shipments for the quarter totaled 38,946 metric tonnes, below the range of guidance previously estimated. The average realised price achieved for zircon concentrate was US$524/t for the September quarter, US$41/t below the achieved price for the previous quarter and reflective of challenging zircon concentrate market conditions in China.

Market Outlook
More recently, following national holidays in China, KMS and Sheffield have observed significant deterioration in the zircon concentrate market. Having sold 38,946 tonnes of zircon concentrate during the September quarter, KMS is observing challenges in securing sales for October and into November. Consequently, Sheffield will be unable to provide guidance of forecast zircon concentrate sales for the December 2025 quarter.
Ilmenite concentrate is being sold under an offtake agreement to joint venture partner, Yansteel. Product pricing is fixed price per percent of TiO2 content contained within the ilmenite concentrate, with an assumed TiO2 content of 38.5% resulting in a contract value of US$123/t.
Sheffield will continue to keep the market informed of material developments concerning the zircon sales and business operations of KMS and the Thunderbird Mineral Sands Mine.
Financial
Underlying C1 cash costs was $201/tonne of concentrate, compared with $302/tonne for the previous quarter reflecting the significant productivity improvement and record production achievement for the quarter. Finished goods inventory comprises approximately 100,000 tonnes of ilmenite concentrate and over 30,000 tonnes of zircon concentrate available for shipment as at the end of the quarter.

C1 cash costs per tonne produced (excluding inventory movement) were $218/tonne of concentrate for the September quarter, compared to $308/tonne of concentrate for the previous quarter. The result was driven by a 24% increase in production, coupled with lower shipping costs incurred during the period.
Operating cashflows totalled $9m for the quarter. During the quarter, zircon concentrate customers (including Yansteel) advanced prepayments under sales contracts totalling $13m for the supply of zircon concentrate, assisting with short term working capital requirements.

KMS Senior Secured Loan Restructuring
During the previous quarter, KMS initiated discussions with the senior secured lenders Orion Resources Partners (Orion) and the Northern Australia Infrastructure Facility (NAIF), with a view to resculpting and aligning the future scheduled debt repayments to the revised mine plan, costs and forecast prices (refer to ASX announcement dated 22 July 2025). KMS continues to progress and advance negotiations with senior secured lenders, however there can be no certainty that any amendments to the senior secured loan facilities will be successfully completed during the near term. Sheffield and Yansteel remain sponsors and guarantors to the senior secured loan facilities.

December 2025 Quarter Outlook
As described earlier, given the subdued market conditions in China, Sheffield is unable to provide guidance for the December 2025 quarter.
Sheffield will continue to keep the market informed of material developments concerning the zircon sales and business operations of KMS and the Thunderbird Mineral Sands Mine.
PORTFOLIO DEVELOPMENT
Alongside the KMS interest, Sheffield intends to develop a portfolio of mineral sands interests.
