Iluka Resources

Iluka Resources is Australia's leading mineral sands producer and an emerging integrated rare earths refiner. For seven decades it has mined and processed heavy mineral sands to produce zircon (sand and zircon-in-concentrate) and high-grade titanium dioxide feedstocks (natural rutile, HyTi and synthetic rutile). These feed ceramics, pigment, welding, titanium metal and specialty markets worldwide. Its asset base is wholly Australian: Jacinth-Ambrosia (SA), Cataby and the SR2 kiln (WA, idled since 1 Dec 2025), the Narngulu separation plant, and the newly commissioned Balranald underground mine (NSW). Iluka is now transforming itself through the A$1.7–1.8bn Eneabba rare earths refinery, Australia's first fully integrated refinery for separated light and heavy rare earth oxides. Eneabba is backed by a A$1.65bn non-recourse Australian Government loan and is due to commission in 2027. Iluka also holds a ~20% stake in Deterra Royalties. The investment case is a cyclical cash-generating base funding a strategic, geopolitically advantaged rare earths platform.

Company's own description

Iluka describes itself as a global critical minerals company. Its expertise spans exploration, development, mining, processing, marketing and rehabilitation. It cites more than 70 years of industry experience and calls itself a leading producer of zircon and of the high-grade titanium dioxide feedstocks rutile and synthetic rutile. Iluka also states that it has established a significant position in rare earths. Its products are used in technology, construction, medical, lifestyle, defence and industrial applications. Operations and projects are in Australia, supported by a globally integrated marketing network. Exploration is conducted internationally, and Iluka manages rehabilitation of legacy operations in the United States and Australia. (Company profile text used in its website and annual report boilerplate; corroborated by data-provider business descriptions.)

The 2025 Annual Report frames the year as one of contrasting dynamics. Mineral sands faced subdued demand and disruption in the pigment industry. Rare earths, by contrast, were recognised by governments and consumers as a strategic priority, validating the diversification Iluka has pursued since 2022 (FY2025 Results release, Managing Director's commentary).

Business model

Product model (100% product sales). Iluka earns revenue almost entirely from bulk mineral product sales. There is no service, subscription or licensing revenue of note. The exceptions are:

• its equity-accounted share of Deterra Royalties' profit (FY2025: A$30m; FY2024: A$22m);

• minor by-product sales of ilmenite, activated carbon, gypsum and iron concentrate.

Contracting. Zircon is sold through a mix of quarterly and contract arrangements. Iluka has historically used a published Zircon Reference Price, and it sets prices quarterly in negotiation with customers. Synthetic rutile has historically been sold under multi-year take-or-pay contracts with Western chloride-pigment producers. Those contracts were renewed at the start of 2023 for four years, then rebalanced in 2025. For 2026 they cover:

• 110kt of synthetic rutile;

• 10kt of rutile;

• 12kt of HyTi;

• 100kt of ilmenite;

all with fixed or floor prices underpinning minimum contracted revenue of A$240m (Quarterly Review to 31 Dec 2025).

Rare earths model (from 2027). Iluka will sell separated rare earth oxides — NdPr, Dy, Tb and others — under offtake contracts. The first offtake (June 2026) sets price at the higher of a negotiated minimum price and a market-linked price, so that pricing is independent of China-dominated benchmarks.

Capital allocation. Iluka's dividend framework distributes a minimum share of mineral sands free cash flow not needed for investment (historically described as a minimum 40% of free cash flow). It passes through 100% of dividends received from Deterra Royalties. FY2025 Deterra dividends received were A$23m, and a A$13m Deterra dividend was received in H1 2026 for distribution.

Value chain position

Iluka is an upstream-to-midstream producer:

1. Exploration in Australia (Eucla Basin, Perth Basin, Murray Basin) and the USA (Idaho).

2. Mining of heavy mineral ore, by dry mining, dredging, or Iluka's proprietary remotely operated underground mining (UGM) method at Balranald.

3. Concentration to heavy mineral concentrate (HMC).

4. Mineral separation at Narngulu (WA). Remnant material has also been processed at North Capel and Eneabba.

5. Upgrading of chloride ilmenite to synthetic rutile in coal-fired rotary kilns (SR2 at Capel; SR1 paused since October 2023).

6. Rare earths refining. From 2027 Iluka will move further downstream into cracking, leaching and solvent-extraction separation to produce individual rare earth oxides at Eneabba.

Iluka does not make pigment, zirconium chemicals, ceramics, metals or magnets. Its customers do.

Customer types and end-markets

Independent characterisation

Iluka is in the middle of a structural transition. It is moving from a pure-play, cyclical mineral sands producer whose earnings are geared to Chinese ceramics demand and Western pigment demand, towards a hybrid. That hybrid pairs a sub-scale but strategic rare earths refiner with a mineral sands business now operating at reduced capacity.

The mineral sands business has moved from record profitability in 2022 (mineral sands EBITDA margin 53–56%) to near breakeven in H1 2026 (9% margin). The drivers are:

• weak pigment demand and capacity closures in Europe and China;

• Chinese competition in zircon and low-grade rutile;

• the loss of Venator volumes;

• the idling of Cataby and SR2.

Meanwhile, the balance sheet has moved from net cash to group net debt of A$1.15bn at 30 June 2026. That debt is predominantly non-recourse government debt (A$877m in rare earths). Value is therefore increasingly concentrated in a single, not-yet-commissioned asset (Eneabba). Its economics depend on rare earth pricing outside China, on feedstock diversification and on execution.

Stated strategy themes (2025 Annual Report, FY2025 and H1 2026 releases)

Management's recurring framing rests on five themes:

1. Diversification of mineral sands and rare earths as complementary businesses.

2. Operational and market discipline — producing to demand and not chasing volume into a weak market.

3. Capital allocation discipline, including a dividend framework with 100% pass-through of Deterra dividends.

4. Balance sheet management.

5. Disciplined execution of Balranald and Eneabba.

Management describes external developments as having "validated Iluka's approach." The Chair framed 2026 as a year of "laser focus" on completing Eneabba (ASA AGM report). The H1 2026 release states that 2026 is "an important year of execution."

Strategic initiatives (last 24 months)

ESG commitments

Rehabilitation leadership (2022 Golden Gecko Award for the Flora Restorer seeding machine) and safety metrics form part of the stated strategy.

Medium-term targets and guidance

Iluka does not publish multi-year financial targets.

• Z/R/SR production of 265kt.

• Cash costs of A$420m, including A$140m of Balranald production costs.

• Unit cash cost of A$1,585/t, distorted by the Balranald ramp-up.

• Mineral sands capex of A$60m and rare earths capex of A$600m.

The Balranald investment case targets steady state from mid-2026. Eneabba's design capacity is ~3,500tpa NdPr and ~170tpa DyTb from the Eneabba stockpile alone, with more from third-party feeds.

Mineral Sands — zircon

Zircon Premium. High-purity zircon sand (ZrSiO₄) with low iron and titanium impurities and high brightness/whiteness.

• Target customers: ceramic opacifier and frit makers (tiles, sanitaryware), zirconium chemical producers, precision investment casting.

• Main sources: Jacinth-Ambrosia and Balranald (Balranald is described as rich in premium zircon).

• Pricing: quarterly negotiated; Iluka historically published a Zircon Reference Price.

• Weighted average zircon premium and standard price: US$1,882/t in FY2024, US$1,643/t in FY2025, US$1,502/t in Q4 2025, and US$1,546/t in Q2 2026 with further increases expected in Q3 2026 (Quarterly Review to 30 Jun 2026).

Zircon Standard. Lower-specification zircon sand with marginally higher impurities, sold for ceramics, refractories and foundry uses where whiteness is less critical. It is reported together with premium.

Zircon-in-concentrate (ZIC). A lower-grade intermediate concentrate sold mainly to Chinese processors, who finish it themselves. Production is recognised on sale.

• FY2025 ZIC sales were a record 110.7kt, up 70%. Iluka optimised processing of remnant material through all separation facilities (Eneabba, North Capel, Narngulu) as the market sought lower-cost material.

• 2026 guidance is 50kt.

• The weighted average for all zircon products including ZIC was US$1,422/t in FY2025.

Wimmera zircon (development). Wimmera's fine-grained zircon flowsheet has been tested. Customer testing indicates ~40% of extracted zircon sand is suitable for ceramics, with markets identified for ~60% of all zircon extracted (Quarterly Review to 31 Dec 2025).

Mineral Sands — titanium dioxide feedstocks

Rutile (natural, ~95% TiO₂).

• Customers: welding-electrode manufacturers (premium pricing), chloride pigment producers, titanium sponge producers.

• Sources: Jacinth-Ambrosia and, increasingly, Balranald, whose investment case is ~60ktpa of rutile.

• Price (excluding HyTi): US$1,694/t in FY2024, US$1,216/t in FY2025, US$1,110/t in Q4 2025. The Q4 2025 figure reflects lower-grade (92% TiO₂) sales and pigment weighting.

• Iluka states rutile sales will be weighted to pigment customers as Balranald comes online.

HyTi. Lower-value TiO₂ product (70–90% TiO₂), reported within rutile volumes and sold to pigment and welding customers at a discount to rutile.

Synthetic rutile (SR). Upgraded ilmenite (~88–95% TiO₂) produced in coal-fired rotary kilns. SR2 has ~225ktpa capacity (Argus, Sep 2025); SR1 is a "premium swing" kiln restarted December 2022 and paused since October 2023.

• Customers: Western chloride pigment producers under multi-year contracts.

• Price: US$1,205/t in FY2024, US$1,112/t in FY2025, US$1,073/t in Q4 2025.

• 2026 production guidance is nil, with SR2 idle. Contracted 2026 SR volumes (110kt) are served from inventory.

• Iluka can restart SR2 earlier "should market conditions support a restart."

Ilmenite.

• Chloride ilmenite from Cataby is SR2 feed.

• Sulphate ilmenite is sold to sulphate-route pigment producers; Balranald's investment case includes up to 150ktpa sulphate ilmenite.

• FY2025 ilmenite production was 335kt and sales 51kt.

By-products

Activated carbon (from synthetic rutile processing), gypsum and iron concentrate, sold in small volumes and reported in "ilmenite and other revenue."

Rare Earths

Separated light rare earth oxides (from 2027).

• Products: NdPr oxide (neodymium-praseodymium), plus lanthanum, cerium and samarium/europium/gadolinium fractions where produced.

• Eneabba's design output using the Eneabba stockpile alone is ~3,500t of NdPr per annum once ramped up (Offtake release footnote, 23 Jun 2026).

• Target customers: magnet makers, automotive OEMs, metal/alloy producers.

Separated heavy rare earth oxides (from 2027).

• Products: dysprosium (Dy) and terbium (Tb) oxides — the critical heavy rare earths for high-temperature magnets.

• Design output is ~170t per annum of DyTb from the Eneabba stockpile, with heavy rare earth-rich third-party feeds to add to this (xenotime from Northern Minerals' Browns Range, Goschen concentrate from VHM).

• Iluka positions Eneabba as one of very few facilities outside China that will, by design, produce both separated light and heavy oxides at meaningful scale (H1 2026 call commentary).

Flagship contract. Binding take-or-pay offtake with a "globally recognised automotive company" (unnamed), commencing 2028 for four years:

• 1,200t of magnet rare earth oxides (Nd, Pr, Dy, Tb), about 10% of planned production in the period;

• pricing at the higher of minimum and market-linked prices;

• minimum revenue reported at US$155m over the term (Offtake release; Motley Fool, 23 Jun 2026).

Some secondary sources describe the volume as 1,200t per year. Iluka's release frames it as 1,200t over the period, equal to ~10% of planned output. The primary-source interpretation is used here.

Rare earth concentrates (historical/intermediate). Monazite-zircon concentrate from Eneabba Phases 1–2 was historically sold or stockpiled. It is now retained as refinery feed.
