Tronox Holdings plc

SUMMARY DISCLOSURE

Below are our primary offices and facilities at December 31, 2025. We believe our properties are in good operating condition, and are well maintained. Pursuant to separate financing agreements, substantially all our material U.S., European and Australian properties are pledged or encumbered to support or otherwise provide security for our indebtedness.

Our primary office locations consisted of the following:

Overview of Our Vertical Integration

Tronox is the world's leading vertically integrated manufacturer of TiO 2 pigment. We produce the majority of our internal TiO 2 pigment feedstock requirements internally at our mine and mineral processing facilities. Our supply chain consists of mining operations in South Africa and Australia, separation and upgrading facilities located near our mines where we separate and process raw ore and then “upgrade” the titanium content of the raw ore to produce specialized chloride TiO 2 feedstock materials (titanium slag and synthetic rutile) and seven TiO 2 pigment production facilities located on six continents. The internal TiO 2 feedstocks we produce include titanium slag, synthetic rutile, natural rutile, leucoxene, chloride ilmenite and sulfate ilmenite.

As part of our TiO 2 value chain, we explore, acquire, mine and process heavy mineral sands to produce Heavy Mineral Concentrate (“HMC”) from which the Valuable Heavy Mineral (VHM) titanium and zircon products are made. HMC is produced from heavy mineral sands primarily through spiral gravity concentration at our mines. Mined material is transported to our nearby integrated mineral separation plants (MSP) to separate and concentrate VHMs by gravity, magnetic and electrostatic techniques. Multiple grades of titanium minerals and zircon may be produced from each MSP. The three titanium feedstocks which result from the MSP process (natural rutile, leucoxene and ilmenite) are each handled differently. Natural rutile and leucoxene are ordinarily shipped from the MSP to one of our TiO 2 pigment production facilities. Depending on the TiO 2 content of mined ilmenite, we either use it directly to produce TiO 2 pigment or we upgrade it to produce titanium slag at our two South African smelter operations and synthetic rutile (SR) at our Chandala metallurgical complex in Western Australia. Our internally sourced titanium mineral products provide a secure, long-term low-cost supply of high-grade feedstock for our TiO 2 pigment manufacturing facilities.

There is a high degree of substitutability among natural rutile, synthetic rutile, titanium slag, leucoxene and chloride ilmenite as titanium feedstocks for chloride pigment production. The commercial value of titanium feedstock is a function not only of TiO 2 content and supply and demand balances, but also particle size, trace element geochemistry, logistics and other factors. The global TiO 2 industry is a value-added supply chain, with final product prices for TiO 2 pigment, typically significantly higher than that of chloride or sulfate ilmenite, the backbone of the global titanium mineral supply. The revenue assumptions for titanium feedstocks we applied to determine our reserve estimates, as described below, are based on market intelligence gathered from internal and external experts, sales contracts and historic pricing. The economic assessment is done on a minerals only basis and no value of downstream upgrading is attributed to the minerals units.

In 2025, we produced concentrates of ilmenite, rutile, leucoxene, and zircon from five operations:

–Namakwa Sands, Western Cape, South Africa;

–KwaZulu-Natal (“KZN”) Sands, KwaZulu-Natal, South Africa;

–Northern Operations, Western Australia;

–Southern Operations, Western Australia; and

–Eastern Operations, Murray Basin, New South Wales, Australia.

Ilmenite from our Namakwa and KZN Sands mines in South Africa is converted to titanium slag at our smelters at Saldanha Bay, Western Cape and Empangeni, KwaZulu-Natal, respectively. Ilmenite from our Cooljarloo mine in Western Australia is converted to SR at our Chandala metallurgical complex which is most commonly used as feedstock to our TiO 2 pigment plants at Kwinana and Kemerton, both of which are south of Perth in Western Australia.

Mining Operations

Tronox owns and operates five mining and mineral processing operations, each including one or more heavy mineral sand (“HMS”) mines producing HMC which is separated into valuable co-products, primarily zircon and TiO 2 feedstocks --- ilmenite, natural rutile or leucoxene --- in a dedicated mineral separation plant.

In South Africa, the Namakwa Sands operations include two open-pit mines at Brand-se-Baai, each with a dedicated primary gravity concentration plant and a secondary concentration plant (SCP) that processes the HMC from both primary plants. Products from the SCP are further processed to finished mineral products at a nearby MSP in Koekenaap. Ilmenite product is further processed into titanium slag and pig iron at a two-furnace smelter at Saldanha, Western Cape, South Africa which is two hundred kilometers south of Koekenaap. The KZN operations have an open pit hydraulic mine at Fairbreeze with a primary gravity concentration plant, a MSP at nearby Empangeni alongside a two-furnace smelter complex, and export facilities at the port of Richards Bay.

In Australia, the Northern Operations consist of the Cooljarloo dredge mine and floating primary gravity concentration plant, and the Chandala metallurgical complex, consisting of a mineral separation plant and SR plant. The Southern Operations consist of a dry open pit mine and primary concentration at Wonnerup and a mineral separation plant at Bunbury.

The Eastern Operations in the Murray Basin of Australia consists of a dry open pit mine at Atlas Campaspe and a mineral separation plant at Broken Hill, NSW. The Snapper mine ceased production in April 2022 after 12 years of production. The Gingko and Crayfish mines ceased production in June 2024 after 20 years of production. Construction at Atlas commenced in 2022 and ramped up to full production in the first quarter of 2023. The Atlas Campaspe mine is abundant in natural rutile and high value zircon and will be a significant source of high-grade ilmenite suitable for direct use or upgraded feedstock production.

Mineral Properties

Mining and Mineral Tenure

S-K Subpart 1300 requires us to describe our rights to access and mine the minerals we report as reserves and to disclose any change in mineral tenure of material significance. Our heavy mineral exploration and mining activities in South Africa and Australia are regulated by the South African Department of Mineral Resources, the Western Australia Department of Mines, Petroleum and Exploration, and the New South Wales Department of Primary Industries and Regional Development - Resources. All exploration and mining activities are subject to multiple levels of environmental regulatory review, including approvals of environmental plans and public comment periods as pre-conditions to granting of mineral tenure.

Mineral Tenure - South Africa

Our two South African mineral sand mining processing chains are operated by Namakwa Sands and KZN Sands, both indirect, wholly-owned subsidiaries of Tronox Holdings plc. The South African Department of Mineral Resources and Energy (“DMRE”) is the regulatory administrator of mineral rights in South Africa, subject to the provisions of the Mineral and Petroleum Resources Development Act (“MPRDA”), No. 28 of 2004, as amended in 2016. The MPRDA vests all mineral rights in South Africa in the national government and establishes conditions for the acquisition and maintenance of prospecting and mining rights. Prospecting rights and mining rights may only be granted by the DMRE. Prospecting rights are granted for a maximum period of five years and can be renewed once for an extension of up to three years. Prospecting rights may be revoked for non-compliance with the terms of the prospecting right.

Mining right applications require additional approvals by the Department of Environmental Affairs (“DEA”) of an Environmental Management Program (“EMP”) and an Integrated Water and Land Use License.

Mining rights are valid for up to 30 years and may be extended by 30-year renewals, subject to compliance with conditions established in the EMP and by the MPRDA. Environmental permitting and compliance are co-administered by the regional offices of DEA and Development Planning. All rights, licenses and permits for Namakwa Sands and KZN Sands are in good standing.

On the Western Cape of South Africa, Tronox holds mining rights over an area of 19,205 hectares (47,457 acres) and surface rights totaling 17,111 hectares (43,542 acres) at the active mining site near Brand-se-Baai, commonly referred to as our Namakwa Sands operation. On the Eastern coast of South Africa, Tronox controls mining and prospecting rights covering approximately 4,041 hectares (9,986 acres) at KZN, where surface access rights are either owned directly by KZN Sands or secured by agreements with Mondi Ltd. A further 4,790 hectares (11,836 acres) of prospecting rights are held by a direct, wholly-owned subsidiary of KZN Sands at the nearby Port Durnford and Waterloo project areas which we are currently in the process of converting into a mining right.

Mineral Tenure - Australia

Our Australian mineral properties are divided into the Northern and Southern Operations on the Swan Coastal Plain of Western Australia and the Eastern Operations in the Murray Basin of New South Wales and Victoria. Mining tenements in Australia are managed at the State or Territorial level. In Western Australia, Mining Leases, Exploration Licenses and Retention Licenses are granted and administered by the Western Australian Department of Mines, Petroleum and Exploration, and in New South Wales by the NSW Department of Primary Industries and Regional Development - Resources, under the authority of the Western Australian Mining Act 1978 and the New South Wales Mining Act 1992, respectively. Principal environmental authorities are the Western Australian Department of Water and Environmental Regulation and the NSW Environment Protection Authority.

At the Northern Operations in Western Australia, Tronox controls mining leases, exploration and other licenses and rights covering a total 45,322 hectares (111,993 acres). Mining and Public Environmental Review plans are approved for the Cooljarloo mine and approval to extend the environmental plans for Dongara were recently approved. Environmental Protection Agency approval of Cooljarloo West has also been approved. The main Cooljarloo Mining Lease covers 9,744 hectares (24,078 acres). We hold 11 mining leases at the Dongara project and one exploration license. Three older mining leases are held at our Jurien property, the site of a former heavy minerals open pit mine operated by another party in the 1970’s.

Tronox holds mining and exploration licenses totaling 512,410 hectares (1,306,693 acres) in the South Perth Basin and Murray Basin heavy mineral provinces of Australia.

The Southern Operations in the southwest of Western Australia comprises 29 mining leases, 1 exploration license, 2 retention licenses, 2 general purpose leases, and 2 miscellaneous licenses totaling 8,485 hectares.

Tronox holds 6 mining leases, 15 exploration licenses, and 2 retention licenses in our Eastern Operations in the Murray Basin of New South Wales and Victoria. The tenements cover approximately 435,900 hectares (4,359 sq km). Four mining leases west of Pooncarie, NSW cover approximately 6,800 hectares (16,803 acres) surrounding our rehabilitation sites at Snapper, Ginkgo and Crayfish. Two mining leases of 6,159 hectares are located at the Atlas Campaspe mining project in NSW.

Mineral Sands - South Africa and Australia

HMS deposits are natural concentrations of granular minerals of high density (conventionally above about 2.85 gm/cm3). Titanium-rich HMS deposit source rocks are typically granitic and/or high-grade metamorphic crystalline rocks. The heavy mineral assemblage of a particular HMS deposit generally reflects the ilmenite, leucoxene, natural rutile and zircon contained in local and regional source rocks. Factors that influence the formation of HMS deposits include erosion of crystalline source rocks, fluvial transport to the coastline, longshore drift, coastal geomorphology, deposition of heavy minerals, and prolonged natural sorting of heavy minerals by water and wind, according to the density, size and shape of HM grains. Post-depositional geological processes that can affect the economic viability of a HMS deposit include in situ weathering, induration of the host sands, and natural preservation or destruction of the HMS deposit.

Not all heavy minerals have commercial value, and a distinction is made between the Total Heavy Minerals (“THM”) and VHM. Typical VHM assemblages include the titanium-iron oxide mineral, ilmenite (FeTiO3); rutile, a premium TiO2 feedstock mineral; leucoxene, a natural alteration product of weathered ilmenite; and zircon, a zirconium silicate (ZrSiO4) valuable for its use in a diverse range of industrial and construction applications. Other HM of commercial value, such as garnet, staurolite, kyanite and monazite, may be recovered as by-products.

Of interest recently is the potential use of monazite, both in contained ore bodies and in stockpiled sources located near the mineral separation processes at Namakwa Sands. Monazite has increasing commercial value due to a high concentration of rare earth metals which can be separated by well-established methods. Rare earths are expected to remain in high demand as demand grows for electric vehicles, wind turbines, and consumer goods that require rare earth-containing permanent magnets. We currently do not know the metallurgical recovery potential for the monazite as our processes have historically focused on traditional value minerals. Given the increasing importance of monazite, we are evaluating new processes to better understand the grade and recoverability of monazite in our mining tenements.

Reporting of Reserves and Resources

The following tables summarize our reserves and resources as well as their contained in situ total heavy minerals (THM) and heavy mineral (HM) assemblages as of December 31, 2025 based on long-term price assumptions. The sole purpose of the operational and related financial data presented is to demonstrate the economic feasibility of the mineral reserves for the purpose of reporting in accordance with subpart 1300 of Regulation S-K, and should not be used for other purposes. The information presented originates from comprehensive techno-economic modelling, which is subject to change as assumptions and inputs are updated, and as a result does not guarantee future operational or financial performance. Consistent with industry standards, Tronox values its mineral reserves based on the prices at which its titanium and zircon mineral products would sell on freely traded markets, as forecasted by third-party industry consultancies.

All of our reserves are reported on the basis of our 100% ownership of in-place, economically extractable ore, determined from comprehensive geological, mining, processing and economic models. Reserve classifications of proven or probable are based on the level of confidence in the appropriate resource estimates. Our residual resources are those areas of mineralized ground which have either had insufficient drilling to confidently define the shape, grade and recoverability of the valuable minerals as well as not yet having been subjected to a detailed assessment of the impact of validated “modifying factors” on the revenue generating potential of a deposit.

Our mineral resource and reserve estimates are based on extensive geological resource models modified by various mining and processing factors and assessed in a techno-economic model for commercial viability. This constitutes a Life-of-Mine-Plan (LOMP) for each operation. Our LOMP and reserve estimates are optimized with respect to anticipated revenues and costs. Assumptions are developed from our extensive experience and include mining parameters, processing recoveries, operating costs, foreign exchange, and rehabilitation. Each of our operations reconcile predicted mining and processing metrics with actual production and recovery data on a monthly basis. Our models are updated as necessary and used to determine ore boundaries based on economic assumptions, certain of which are set forth below the following tables. For reserves where there is substantial asset investment post the minerals production stage, parameters that best utilize the whole value chain may take precedence over maximizing value from the minerals business unit, therefore impacting the optimal mining shell and effective cut-off grade.

Not all HMS deposits are alike. Our reserves, as set forth in the table below, have a higher confidence level because we have undertaken sufficient drilling density and validation. Resources present unconfirmed continuity and variability in grade, HM assemblage, or other characteristics, as well as the indeterminate impact of modifying factors, and hence are not classified as reserves.

Within the broad category of resources, inferred resources have a lower level of geological confidence than do indicated resources with measured resources being the highest confidence level from a geological perspective. Only indicated resources and measured resources can be converted to reserves with proven reserves having a higher level of economically exploitable confidence than probable reserves. The following tables have been determined to be economically- exploitable by individuals competent and qualified to act under the new disclosure requirements as “Qualified Persons.” Each of the Qualified Persons is an employee of an indirect, wholly owned subsidiary of the Company.

For clarity, in the tables below, our reserves have been excised from the resources as they can be proven to be profitably mined and processed. The remaining deposit exceeds cut-off grade, but have not yet been demonstrated to be profitable by virtue of either recoverable grade, operating cost or capital required to develop, are separately defined as resources.

The overall 2.5% decrease in resources at all operating sites in 2025 as compared to 2024 is primarily attributed to the reclassification of material into reserves at Cooljarloo and KZN.

The overall 0.8% decrease in reserves at all operating sites in 2025 as compared to 2024 is primarily attributed to mining depletion, which has been mostly offset by increases in reserves at Cooljarloo and KZN.

TRONOX MINERAL SANDS - 2025-2024 RESOURCES(1)

(See footnotes below the following table.)

Abbreviations, Definitions, and Notations

Reserves—mineralized material inclusive of dilution, determined to be economically and legally exploitable as of December 31, 2025, classified as either Probable Reserves or Proven Reserves, based on level of confidence.

Resources– mineralized ground which has either had insufficient drilling to confidently define the shape, grade and recoverability of the valuable minerals as well as not yet having been subjected to a detailed assessment of the impact of validated modifying factors on the revenue generating potential of a deposit.

LOMP— Life-of-Mine-Plans (LOMPs) have been developed for each mine site by teams of Tronox professionals based on the mineral reserves and resources, realistic assumptions of geological, mining, metallurgical, economic, marketing, legal, environmental, social, governmental, engineering, operational and all other modifying factors in sufficient detail to demonstrate at the time of reporting that extraction is reasonably justified.

THM— total heavy minerals, densities >2.85 g/cm3 regardless of commercial value

VHM— valuable heavy minerals, including Ilmenite, Rutile, Leucoxene & zircon, reported as percentage of THM.

Minor computational discrepancies may be due to rounding.

Cooljarloo Dredge Mine reserves include Cooljarloo and Cooljarloo West

Key Assumptions— economic viability is determined by techno-economic modeling that integrates geological, analytical and geotechnical databases, mining parameters, metallurgical recoveries, known or forecast operating costs, cost of capital, and product sales prices at time of production. Historical sales prices by themselves are unreliable predictors of future prices, and our forecasts are based on our private contracts, internal and external market research.

Disclosures of mineral reserves traditionally include a cut-off grade, the grade in a mineral deposit below which material cannot be profitably mined and processed. However, economic exploitability is determined by many modifying factors other than grade, and most modern mining operations, including ours, use detailed computer models utilized by employees who possess the experience and technical expertise to identify what parts of a deposit are economically exploitable.

Production forecasts of commercial-quality titanium mineral and zircon concentrates from reserves are taken from our Life- of-Mine Plans. Mining recoveries are typically close to 100%, but metallurgical recoveries in each concentration step can vary widely, as a function of ore and mineral characteristics. We apply recovery factors based on actual operating data.

Mineral reserve estimates, life-of mine projections, and revenue assumptions are inherently forward-looking and subject to market conditions, uncertainties, and unanticipated events beyond our control.

INDIVIDUAL PROPERTY DISCLOSURE

Tronox Northern Operations (Cooljarloo)

Tronox Management Pty Ltd is a subsidiary of Tronox Holdings plc and is the operator of Tronox Northern Operations which includes:

•Cooljarloo Mine, 170 km north of Perth, where heavy mineral concentrates are produced from dredge mining operations. The net book value of Cooljarloo, inclusive of mining and beneficiary equipment located in Western Australia as well as relevant mining tenements, as of December 31, 2025 was $380 million;

•Cooljarloo West and Osprey deposits, which conjoin the Cooljarloo Mine operations;

•Chandala Processing Plant, 60 km north of Perth, where the heavy mineral concentrates (HMC) are separated into saleable mineral products and also where ilmenite is further upgraded to synthetic rutile;

•The laboratory and mineral testing facility is also located at the Chandala site.

Mining tenements in Australia are managed at the State or Territorial level. In Western Australia, Mining Leases, Exploration Licenses and Retention Licenses are granted and administered by the Western Australian Department of Mines, Petroleum and Exploration.

Tronox operates under four (4) mining leases which are 100% held by Tronox Management Pty Ltd., a wholly owned subsidiary of Tronox Holdings plc as shown in the table below.

Mining Tenement Schedule

Tronox has one active mine site at Cooljarloo that was originally controlled by a State Agreement Act with the State of Western Australia. This area was covered by State Agreement Act MSA 268 which was originally granted in 1989 for a period of 21 years. It was extended for a further 10-year term which expired in 2020. MSA 268 was replaced by Mining Lease M70/1398 which will expire in 2041.

Cooljarloo West is located within Mining Leases 70/1314 and 70/1333. Osprey is located within Mining Lease 70/1413. Granting of rights to mine are pending environmental approval.

The minerals in Western Australia belong to the Crown (the State of Western Australia) and Tronox is obligated to pay a 5% revenue- based royalty on saleable mineral products. This is factored into the valuation models and optimizations conducted by Tronox.

A private royalty of 10c/t of VHM is paid for a portion of the northern section of the Cooljarloo tenement. Based on the current mine plan, mining in this royalty agreement area will cease by 2025 and the amounts paid are not material to the business.

On Mining Lease 70/1333 Tronox agrees to pay the previous holder of the exploration lease a royalty of 1% of a previously agreed price for each tonne of Valuable Heavy Mineral recovered from the Mining Lease. The cost will also be immaterial to the business.

The Cooljarloo Mine is located at coordinates latitude 30°39'S and longitude 115°27'E.

Location of Western Australian Operations

The Brand Highway is a major bitumen road running from Muchea, just North of Perth up to Geraldton, a provincial city 450 km north of Perth. The road runs just past the Western boundary of the Chandala site and just past the Eastern boundary of the Cooljarloo mine site. It is suitable for all weather and wide loads.

There is a 132 kV power line that also runs from Perth to Geraldton which passes near the Chandala site and through the mine site. Tronox has a substation on its property that draws and reticulates 22 kV power from the sub-station connected to the main high voltage distribution line. At the various locations power is ultimately transformed down to 415 V. The same situation exists for Chandala and it gets power from the same main line.

Two gas pipelines run just a kilometer to the West of the Chandala site. They are referred to as the Dampier to Bunbury Natural Gas pipeline (DBNG) and also the Parmelia line which originates just south of Geraldton. The Chandala Mineral Separation Plant currently gets supply for driers and re-heaters from the Parmelia line.

The countryside surrounding both Chandala and Cooljarloo is relatively flat. This made the construction of buildings and fixed plant straightforward. Storage ponds for solid waste from the MSP were able to be made quite shallow only being a few meters above natural ground level.

There is a large freshwater aquifer (Yarragadee) immediately to the west of the Brand highway adjacent to the Chandala site. Tronox has a borefield there that supplies the licensed 1 megaliter per annum of water that the site requires. Even in times of severe drought, supply from this aquifer has never been at risk. Cooljarloo draws from an extensive field of relatively shallow bores and also an extension of the Yarragadee aquifer. To limit pumping distances, it has been preferable to have multiple smaller bores around the site since the dredging operation has travelled more than 40 km within the mining lease area since 1989. Tailings disposal at Cooljarloo is all placed behind the dredging operations and incorporated into the rehabilitated profile. There is a registered waste disposal pit where wastes from the MSP, the Synthetic Rutile plant and from the Kwinana pigment plant are licensed to be stored. These pits cells are constructed above the water table and are clay lined. When each cell is full it is capped to minimize the ingress and egress of water.

The Chandala operation utilizes two port facilities. The Port of Fremantle is used for export of bagged and containerized mineral products and the Port of Bunbury is used for bulk shipments. Tronox rents storage and warehousing facilities at or nearby to those sites.

For Cooljarloo there is a well-equipped modern permanent single person’s quarters (SPQ), capable of accommodating up to 160 people or approximately 70% of the work force. At Chandala, employees and contractors are primarily sourced from the Perth metropolitan and surrounding areas.

History

Cooljarloo

The Cooljarloo tenements were originally pegged in 1972 by Kamilaroi Oil Company following the discovery of the Eneabba Deposits. They were subsequently obtained by Yalgoo Minerals Pty Ltd and Tific Pty Ltd in 1985 which became part of TiO2 Corporation NL (TiO 2).

In 1988 prior to mining commencing, the Cooljarloo Joint Venture was formed between Kerr-McGee Chemical Corp and Minproc Ltd, subsequent reorganizations of both partners led to 100% ownership under Tronox in 2012.

No geological data generated by owners prior to the formation of the Cooljarloo Joint Venture is in use.

Cooljarloo West

In 1990 drilling by Peko Exploration Ltd delineated a zone of deep low-grade mineralization but further drilling failed to intercept economic mineralization. The tenements were relinquished in 1992.

Image Resources later pegged the area which were acquired by Tronox in 2005. Drilling completed by Tronox in 2007 delineated the deposits named Woolka Road, Harrier and Kestrel and Resources and Reserves are based only on data generated by Tronox.

Cooljarloo Summary of Mineral Resources as of December 31, 2025

(1) Mineral resources are exclusive of mineral reserves.

(2) Price assumptions used for resource and reserve estimations are $1,906 per metric ton of zircon, $320 per metric ton of Chloride Ilmenite, $1,180 per metric ton of Rutile and $1,220 per metric ton of Leucoxene. Mineral prices used in Reserve estimation are substantially in line with the prices for each of our products published quarterly by independent consulting companies.

For a comparison of the reported resources as of December 31, 2025 with the resources as of December 31, 2024, see table on page 35. The decrease in resources in 2025 as compared to 2024 is primarily attributable to mining depletion.

Cooljarloo Summary of Mineral Reserves as of December 31, 2025

(1) Price assumptions used for resource and reserve estimations are $1,906 per metric ton of zircon, $320 per metric ton of Chloride Ilmenite, $1,180 per metric ton of Rutile and $1,220 per metric ton of Leucoxene. Mineral prices used in Reserve estimation are substantially in line with the prices for each of our products published quarterly by independent consulting companies.

(2) Conversion of in ground grade to saleable product yield (recovery), considering all the losses during mining and processing, is typically 85% for ilmenite, 88% for rutile, 79% for Leucoxene and 83% for zircon.

For a comparison of the reported reserves as of December 31, 2025 with the reserves as of December 31, 2024, see table on page 36. The increase in reserves in 2025 compared to 2024 is primarily attributable to the inclusion of Osprey and 33,000S satellite pits into reserves. This has offset depletion due to mining.

The Cooljarloo project was established in 1988. Being situated on an historical coastline, the ore body is made up of conventional mineral sands strandlines and eminently suited to dredge mining and gravity concentration.

Since commencement, the operation has been running continuously and has thus far consumed 671 Mt of ore at approximately 2.77% HM grade. The current reserves are 304 Mt tons at 1.8% HM grade, which gives a further 15 years of life. The current resources, which are exclusive of reserves, are 239 Mt at 1.6% HM.

Extensive and systematic exploration drilling activities are conducted at Cooljarloo and adjacent deposits on an annual basis to upgrade resources and reserves. Final reserve delineation drilling is completed to a 50m x 40m or 50m x 20m spacing depending on the geological complexities of the orebody. Final drilling is completed three or more years in advance of the mining face to allow timely and accurate mine planning to be completed. Over the past 15 years there has been an average of 52,000 meters of drilling completely annually at Cooljarloo. Drilling will continue in 2026.

Cooljarloo mine has operated with 2 dredges in the one pond since 1999. The original Ellicott Cooljarloo1 dredge operates in tandem with the smaller capacity Neumann built Pelican dredge which was brought into service in 2012. These bucket wheel dredges operate in a purpose-built pond which sits within the ore mining limit. The original dredge and concentrator were sized to operate at 12 Mt per annum but the original dredge has progressively been expanded and addition of the second dredge has seen the project expand to a maximum of 25Mt per annum to counteract the impact of lower ore grades and also enable improved resource utilization through economies of scale and increased product values.

A wet concentrator also floats in the dredge pond and is on two pontoons covering 2,250 square meters. Spiral gravity concentrators separate the higher density valuable minerals from the lower density trash mineral and lowest density tailings quartz grains. The spiral circuit consists of five stages. Roughers, middlings, cleaners, recleaners and classifiers. Both dredges pump their feed simultaneously to the floating wet concentrator via floating pipelines and high voltage cables for power.

Over the past 37 years of operation the metallurgical circuitry of the wet plant has remained relatively unchanged save for expanding the throughput to approximately 2850 tph. This allowed the processing of lower grade ore which has been shown to have a better revenue to cost ratio compared to the original project assumptions. At the time of the capacity increase, spirals that were at the end of their useful life were replaced with more modern units, of higher efficiency, to cope with both additional throughputs, the lower average feed grade, higher clay fines in the ore and maintain an acceptable mineral recovery.

HMC at Cooljarloo is loaded by front end loader into 93 tonne triple road trains for haulage to the Chandala Mineral Separation Plant (MSP). Both the mine and MSP are based on physical separation processes. There is no need for chemical or physical alteration to achieve good product recovery and quality. Attritioning is a critical process step to ensure clean mineral surfaces that are responsive to the electrostatic HT separators. The attritioned HMC is presented by filter belt to a natural gas fired drier that not only removes the moisture but heats the mineral so that it is most responsive to the primary stage electrostatic separation circuit.

The unit operations at the MSP are many and varied but the significant ones are as follows:

•vibrating and reciprocating woven wire screening;

•mechanical slurry attritioning;

•gas fired fluid bed drying, reheating and cooling;

•HT Roll, Coronastat and Plate electrostatic separators;

•Rare Earth Drum, Rare Earth Roll, Induced Roll and Semi-Lift magnetic separators;

•Hydrosizing; and

•spiral gravity and centrifugal jig concentrators.

The equipment and infrastructure at both Cooljarloo and Chandala are in good order having been upgraded several times such that the total throughput of the mining operation now averages 21 Mt per annum and whilst the MSP has not needed capacity increase, updated technology and implementation of continuous improvement programs have resulted in significant increases in mineral recoveries.

Since Cooljarloo is an operating mine and processing plant, capital is mostly a sunk cost. There is minor stay in business capital incurred annually and there is US$55M of capital forecast with the move to the nearby Cooljarloo West dredging orebody expected in approximately 2033.

Regional location of Atlas/Campaspe Project

Atlas

The Atlas mine site is located in southwestern New South Wales, 120 km northeast of Mildura and 90 km north of Balranald. Access to the license area is via the Balranald Ivanhoe Hwy, the Boree Plains – Gol Gol road and then through the official Atlas Mine Access Road. The Atlas mine consists of a centrally based Wet Concentrator Plant (WCP) and a Dry Mining Unit (DMU) both rated to 500 tph.

An on-site 200-person accommodation village has been constructed to house the workforce and consists of permanent and demountable buildings and facilities such as: Administration and Office Building; Workshops; Process Area Crib Room and Amenities; Gymnasium; Basketball Court and Main Store. Electrical power is supplied directly from a centralized 5 Mwh diesel generation system.

Hydrological investigations identified a bore field location at the Northern end of the mine path, approximately 5km from the central start-up pit location. This bore field supplies water for the mining operations and ancillaries. A total of seven bore pumps supply the required volume.

A RO Plant and potable water treatment plant sized to deliver 115m3/hour has been installed to supply wash water for the HMC and potable water for site buildings, wash pads and the accommodation village.

A communication building is located adjacent to the communication tower for telecom and the Local Area Network (LAN). Data and telephone connection between the communications building, process area, administration area and accommodation village are via a buried fiber optic cable.

HMC from the Atlas mine is transported by a combination of trucks and train. The road network consists of approximately 37 km of existing unsealed roads between the Atlas-Campaspe Mine site access road and the intersection with the sealed Balranald-Ivanhoe Road. The remaining section is a 138 km long bitumen road leading to the Ivanhoe rail siding. HMC is loaded into a train for transport to the Broken Hill Mineral Separation Plant (BH MSP) over approximately 301 km of railway.

History

In the Murray Basin fine heavy mineral occurrences were identified from 1982 to 1986 by Rio Tinto. Subsequently many smaller, coarser and high-grade deposits were also identified, and these formed the first mineral sands mines to be developed in the region. Bemax Resources discovered the Ginkgo, Snapper and Crayfish deposits at Pooncarie in the early to mid-2000’s. Mining commenced at Ginkgo in 2005 and Snapper in 2010. Mining at Snapper was completed in April 2022, Crayfish was completed in July 2023 and Ginkgo was completed in June 2024.

The Atlas-Campaspe Project replaced production from the completed Snapper, Ginkgo and Crayfish deposits. Atlas commenced full production in early 2023.

Atlas-Campaspe Summary of Mineral Resources as of December 31, 2025

(1) Mineral resources are exclusive of mineral reserves.

(2) Price assumptions used for resource and reserve estimations are $1,495 per metric ton of zircon, $246 per metric ton of Chloride Ilmenite, $162 per metric ton of Sulfate Ilmenite, $1,088 per metric ton of Rutile and $314 per metric ton of Leucoxene (East). Mineral prices used in reserve estimation are substantially in line with the prices for each of our products, published quarterly by independent consulting companies.

For a comparison of the reported resources as of December 31, 2025 with the resources as of December 31, 2024, see table on page 35.

Atlas-Campaspe Summary of Mineral Reserves as of December 31, 2025

(1) Price assumptions used for resource and reserve estimations are $1,495 per metric ton of zircon, $246 per metric ton of Chloride Ilmenite, $162 per metric ton of Sulfate Ilmenite, $1,088 per metric ton of Rutile and $314 per metric ton of Leucoxene (East). Mineral prices used in reserve estimation are substantially in line with the prices for each of our products, published quarterly by independent consulting companies.

(2) Conversion of in ground grade to saleable product yield (recovery), considering all the losses during mining and processing, is typically 96% for ilmenite, 92% for rutile, 87% for Leucoxene and 79% for zircon.

For a comparison of the reported reserves as of December 31, 2025 with the reserves as of December 31, 2024, see table on page 36. The decrease in reserves in 2025 as compared to 2024 is primarily attributable to mining depletion.

Construction at Atlas commenced in 2022 and ramped up to full production in the first quarter of 2023. The Atlas deposit is mined using a dry mining method for both the overburden stripping and ore extraction.

We believe the equipment and infrastructure (including the DMU, WCP and all associated infrastructure) at Atlas is in good condition.

Dry mining at Campaspe is expected to replace production from Atlas when Atlas finishes during 2028. Detailed design work and additional approvals are presently being undertaken.

Extensive and systematic exploration drilling activities have been conducted at Atlas and Campaspe on an annual basis to upgrade resources and reserves. Final reserve delineation drilling is completed to 100m x 20m spacing. Final drilling is completed three or more years in advance of the mining face to allow timely and accurate mine planning to be completed. As such, all drilling has been completed at Atlas. Final infill drilling has also been completed for the first five (5) years of mining at Campaspe. Over the past 13 years there has been an average of 50,000 meters of drilling completed annually at Tronox’s Eastern Operations. Drilling will continue at Campaspe and surrounding areas in 2026.

Namakwa Mine

Tronox Mineral Sands Pty Ltd is a subsidiary of Tronox Holdings Plc and holds 100% of the rights at the Namakwa Sands Operations, which is located along the west coast of the Western Cape province, South Africa. The Namakwa Sands Operations includes:

•The Northern operations consisting of the Namakwa Sands Mine at Brand-se-Baai and the Mineral Separation Plant at Koekenaap.

•The Southern operations that consist of the Smelting Operations at Saldanha Bay along with administrative headquarters.

Run of mine production at the Namakwa Sands Mine comes from two shallow open-cast mines where excavators and front-end loaders extract free-flowing and lightly cemented sand. The ore is conveyed to two primary concentrator plants (PCP) that utilize wet spirals to produce a heavy mineral concentrate. These concentrates are pumped to a secondary concentrator plant (SCP) where wet high-intensity magnetic separators (WHIMS) and spirals are used to produce a zircon-rich non-magnetic concentrate, and a magnetic concentrate comprising mainly ilmenite. An ilmenite rich secondary stream from the SCP is reprocessed at a separate plant called the UMM Plant to produce a crude ilmenite. SCP and UMM concentrates are separately trucked to and treated at the MSP near Koekenaap, where a series of magnetic and electrical high-tension separators are employed to produce finale saleable ilmenite, rutile, and zircon products. These products are transported from the Mineral Separation Plant to the Smelter using the Saldanha-Sishen railway network.

The Southern Operations consist of the administrative headquarters and smelter operations and are located 3 km from the Saldanha export harbor. The smelting process comprises the carbonaceous reduction of ilmenite using DC arc furnaces to produce titanium slag and pig iron. The received rutile and zircon products as well as the titanium slag are stored in on-site silos from where it is distributed in bag, container, or bulk shipment format.

Mining tenements in South Africa are managed at a national level. In the Western Cape, Mining Rights and Prospecting Rights are granted and administered by the South African Department of Mineral Resources and Energy (DMR&E).

The Mining Rights for Namakwa are shown in the table and figure below.

Tronox Mining Rights, west coast of South Africa

The net book value of the Namakwa Sands mine, inclusive of mining and beneficiary equipment located in the Western Cape of South Africa as well as relevant mining tenements, as of December 31, 2025 was $552 million. The Namakwa Sands Mine is located at coordinates 31°16’S and 17°54’E.

Location of Western Cape operations

Potable water is sourced from the Olifants River Irrigation Scheme canal system. Water is distributed to the MSP and Brand-se-Baai (BsB) for process and domestic use. Water is pumped to BsB via a 56 km pipeline at the rate of 280 m3/h. This line also provides water to farmers along the line and rehabilitation areas at the Namakwa Sands Mine. Namakwa Sands holds servitude rights in the area adjacent to the tar sealed road between the Mineral Separation Plant and the Mine. Seawater is used in the primary and secondary separation processes and is pumped via the seawater pump station installation close to the Namakwa Sands Mine.

ESCOM supplies the MSP via the 132 kV line from the Juno substation. A 132/22 kV, 20 MVA transformer from ESCOM supplies both the MSP and a local farm.

The minerals are transported with purpose-built trailers and trucks between the Namakwa Sands and the MSP at Koekenaap. The trucks travel on a tar seal road constructed for this purpose. A Sishen-Saldanha railway line connects the MSP and Smelter sites. The minerals are transported from the MSP to the Smelter/port storage in closed container trucks, to prevent mineral losses and contamination.

History

Exploration for heavy minerals along the coastal strip of southwest Africa led to the discovery and subsequent delineation of the Namakwa Sands deposit near Brand-se-Baai in 1987. In September 1994 Anglo Operations Ltd commenced mining and processing at the West mine ore body. In 2008 Exxaro Resources acquired the Namakwa operations from Anglo and then in 2012 Tronox acquired 74% of Namakwa Mineral Sands Pty Ltd. In 2021 Tronox acquired the whole of Namakwa Mineral Sands Pty Ltd.

Namakwa Sands Summary of Mineral Resources as of December 31, 2025

(2) Conversion of in ground grade to saleable product yield (recovery), considering all the losses during mining and processing, is typically 68% for ilmenite, 63% for rutile, and 63% for zircon.

For a comparison of the reported reserves as of December 31, 2025 with the reserves as of December 31, 2024, see table on page 36. The decrease in reserves in 2025 as compared to 2024 is primarily attributable to mining depletion.

The operations at Namakwa Sands were originally established by Anglo in 1996 and have operated continuously since that time. Open-cast mining, also known as strip mining, both classified as surface mining techniques, takes place in two distinct areas known as the East and West Mines. The East Mine comprises predominantly shallow mineral sands stripping, whereas the West Mine entails shallow stripping of mineral sands followed by a deeper open-cast mining operation recovering lightly cemented materials to about 40 meters.

More than 200,000 meters of drilling has been completed to date, to define the pre-mine Namakwa mineral resources base from surface down to bedrock. In-fill drilling, assaying and metallurgical test work will continue over the next decade with the strategy to upgrade current mineral resources to fully measured status, as well as converting mineral resources to mineral reserves, with a focus on proven mineral reserves realization.

The mining and mineral processing flowsheet and equipment of the Northern Operations have remained basically the same since the last throughput upgrade in 2008. The equipment and infrastructure at both mines are in sound working order, having been upgraded such that the total throughput of the mining operations now averages around 23 Mt per annum. A major mine development project, is to be operational in 2026 is currently in the execution stage to extract and beneficiate the deeper lying ore in the East Mine beneath the shallow sands that are nearing its end of life.

Other changes include minor equipment replacements and technology updates, as well as circuit re-configurations as part of an embedded continuous improvement drive. Most recently, a small standalone scavenger plant has been added to the SCP flowsheet to augment attritioned magnetic concentrate production by consuming excess unattritioned ilmenite produced from the WHIMS circuit. Routine work maintenance programs are solidly entrenched, being directed by physical asset care plans targeting the maximum life and efficiency of plant, property and equipment holistically.

KZN Sands

Tronox KZN Sands Operations, which are located along the east coast of the Kwa-Zulu Natal province, South Africa are wholly owned subsidiaries of Tronox Holdings Plc, and include the:

•Fairbreeze Mine, immediately south of the Mtunzini township with the Primary Wet Plant (PWP) situated a further 8 km south of Mtunzini.

•Central Processing Complex (CPC), 50 road km north of Mtunzini, just outside the town of Empangeni, is where heavy mineral concentrates are processed into mineral products and ilmenite is further converted to titanium rich slag and pig iron in two direct current arc furnaces. The laboratory and mineral testing facilities are also located at CPC.

A hybrid mining method is employed at Fairbreeze Mine, utilizing track dozers to break lightly cemented ore layers in combination with high- pressure hydraulic mining using water monitor guns to pump slurried ore to the Primary Wet Concentrator (PWP) for wet gravity recovery of heavy minerals.

The resultant heavy mineral concentrate is trucked to the CPC, which is configured with relatively standard equipment to produce saleable ilmenite, rutile and zircon products. The ilmenite is dispatched to the bordering smelting process encompassing the carbonaceous reduction of ilmenite using DC arc furnaces to produce titanium slag and pig iron. The rutile and zircon products as well as the titanium slag are stored in on-site silos from where it is distributed in bag, container, or bulk shipment format destined for the Richards Bay harbor.

Mining tenements in South Africa are managed at a national government level. In KwaZulu-Natal, Mining Rights and Prospecting Rights are granted and administered by the regional office of the South African Department of Mineral Resources and Energy (DMRE).

The Mining Rights for Fairbreeze are shown in the table and figure below.

Tronox Mining Rights for Fairbreeze

The net book value of the Fairbreeze mine, inclusive of mining and beneficiary equipment located in the Kwa-Zulu Natal province of South Africa as well as relevant mining tenements, as of December 31, 2025 was $459 million. The Fairbreeze Mine is located at coordinates 29°00’S and 31°42’E.

Mining Rights and Surface Ownership

Fresh water is sourced from the Mhlathuze River upgraded installation that originally supplied the Hillendale Mine. This system was upgraded to a pipeline of 750 mm nominal diameter over approximately 33 km to the Fairbreeze Mine and discharging into the raw water dam, from where it is further distributed for mining and minerals processing, as well as potable use.

Bulk electricity supply for the Fairbreeze Mine is from 88 kV and 132 kV ESCOM power lines that run adjacent to the residue storage facilities and feeds the Fairbreeze substation.

Access to the PWP is from off ramps at Bridge 4 on the national highway N2, south of the town of Mtunzini. Road transport for HMC to the MSP at Empangeni, a distance of 50 km, is along the N2 highway utilizing side tipping trucks. Gypsum waste and MSP sand tailings are returned on the backhaul. There is another route between Fairbreeze and the MSP along the R102 that can be used in emergencies. Railway networks in and around the region are suitable for the cargo requirements of the harbor and local industry and are directly connected to the national network for import/export purposes. The Richards Bay harbor operates a very large coal-handling terminal and controls a wide range of import and export cargos. Durban also has port facilities that Tronox uses to export containerized and bagged product from.

History

Natal Mineral Sands (NMS), prospected for mineral sands on Hillendale and Fairbreeze in the northern coast of KwaZulu-Natal during the 1980’s. Iscor Limited purchased NMS in 1994 and mining activities commenced in 2001 at the Hillendale Mine. In 2012, Tronox announced the acquisition of 74% of KZN Mineral Sands operations. Production commenced at Fairbreeze in 2015 and in 2021 Tronox acquired the whole of the remaining portion it did not own of the KZN Sands operations.

Fairbreeze Summary of Mineral Resources as of December 31, 2025

(1) Cutoff grade applied is 1.5% ilmenite.

(2) Mineral Resources are exclusive of mineral reserves. Price assumptions used for resource and reserve estimations are $1,554 per metric ton of zircon, $205 per metric ton of Ilmenite and $1,183 per metric ton of Rutile.

For a comparison of the reported resources as of December 31, 2025 with the resources as of December 31, 2024, see table on page 35. The decrease in resources in 2025 as compared to 2024 is primarily attributable to updated information.

Fairbreeze Summary of Mineral Reserves as of December 31, 2025

(1) Price assumptions used for resource and reserve estimations are $1,554 per metric ton of zircon, $205 per metric ton of Ilmenite and $1,183 per metric ton of Rutile. Mineral prices used in Reserve estimation are substantially in line with the prices for each of our products published quarterly by third-party industry consultancies.

(2) Conversion of in ground grade to saleable product yield (recovery), considering all the losses during mining and processing, is typically 76% for ilmenite, 75% for rutile, and 80% for zircon.

For a comparison of the reported reserves as of December 31, 2025 with the reserves as of December 31, 2024, see table on page 36. The increase in reserves in 2025 as compared to 2024 is primarily attributable to updated information.

In 2001, the Hillendale Mine started to supply HMC concentrate to the CPC, in Empangeni for further minerals processing to saleable mineral products. In 2015 after its useful life, and a production-break, most of the Hillendale Mine’s useful, movable equipment was transferred to the nearby newly established Fairbreeze Mine. Mining at Hillendale Mine was exclusively hydraulic mining, but due to the partially semi-consolidated nature of the Fairbreeze ore bodies, a hybrid open-cast mining method is employed at Fairbreeze Mine, utilizing track dozers to break up the ore where required to assist high- pressure hydraulic mining using water monitor guns to pump slurried ore to the PWP for wet gravity recovery of heavy minerals.

Close to 90,000 meters of drilling has been completed to date to define the pre-mine Fairbreeze mineral resources base from surface down to bedrock. Drilling, assaying and metallurgical test work will continue over the next decade with the strategy to upgrade current mineral resources to fully measured status, as well as converting mineral resources to mineral reserves, with a focus on proven mineral reserves realization. The equipment and infrastructure of the Fairbreeze Mine and PWP are in sound working order, having been upgraded as such that the total throughput of the mining operation averaged around 10 Mt per annum for the initial Phase 1 upgrade. Freshly supplied HMC continued to utilize the existing infrastructure at the CPC, Empangeni, being a fully functional mineral separation plant for zircon, ilmenite and rutile products and smelting operations using two DC arc furnaces to produce of TiO2 slag and pig iron, on the same site.

More recently a Phase 2 expansion of the operation at Fairbreeze Mine was commissioned in order to maintain heavy mineral concentrate (HMC) production due to lower THM grades in the ore. The expansion involves increasing the mining and PWP processing rate to about 16 Mt per annum, which require upgrades to the upfront desliming circuit, a further upgrade of the clay fines thickening and residue disposal equipment, rougher spiral capacity, increased concentrator building and additional process water pumping capacity. Mineral recoveries will be maintained following the expansion as will product quality. A residue storage facility (RSF) called MegaSebeka is currently in place and operational, however with the recent increase in mineral reserves, mine life and planned mining rate, an adjacent area called the Everglades RSF will be constructed nearby.

Otherwise, the MSP used to convert HMC into saleable mineral products is the same that was used for the KZN project’s original mining at Hillendale. Other changes include minor equipment replacements and technology updates, as well as circuit re-configurations as part of an embedded continuous improvement drive. Routine work maintenance programs are solidly entrenched, being directed by physical asset care plans targeting the maximum life and efficiency of plant, property and equipment holistically.
