AUSPOZZ™ PFS SUPPORTS DEVELOPMENT OF AUSTRALIA’S FIRST METAKAOLIN PRODUCTION FACILITY FOR LOW-CARBON CONCRETE

Emerging mineral processing technology company Zeotech Limited (ASX: ZEO, “Zeotech” or “the Company”) is pleased to announce the outcomes of its Preliminary Feasibility Study (“PFS”), which has delivered a compelling business case and comprehensive technical and financial validation for the Company’s AusPozz™ Project (“the Project”).

HIGHLIGHTS

  • Project cashflow of $1,014m after-tax and earnings before interest, tax, depreciation and amortisation (“EBITDA”) of $1,604m over Life of Mine (“LOM”).

  • Net Present Value (“NPV8”) of $406m after-tax, and Internal Rate of Return (“IRR”) of 42% after-tax.

  • Initial capital cost of $115m, with a Payback Period of 2.1 years from free cash flow after commissioning the AusPozz™ Manufacturing Facility.

  • Project life of 20 years supported by a subset of the total Mineral Resource comprising 10.87 Mt of plastic and kaolinite clay classified as Measured and Indicated Resource.

  • Early cash flows from direct shipping ore (“DSO”) operations reduce capital requirement to approximately $95m, including all Project working capital needs.

  • Production targets of 300,000 tpa AusPozz™ and 151,000 tpa of Kaolin DSO.

  • Commercial interest validated by a sales/specifier opportunity pipeline of 65 active leads and Memorandums of Understanding (“MOUs”) with major industry players - Holcim Australia (“Holcim”) for AusPozz[TM] and Jiangsu Mineral Sources International Trading Co, China (“MSI”) for Kaolin DSO products.

  • Projected workforce of more than 140 skilled personnel across mining, logistics, manufacturing, and administration demonstrates the significant economic and social impact the Project could have in rural and regional Queensland.

  • Substantial ongoing reduction of embodied carbon in the built environment would result from 1-for-1 replacement of cement with AusPozz™ in low-carbon concrete. At nameplate production, it could reduce carbon emissions by an estimated 229,800t CO₂-e per annum.

  • The Company intends to transition to a Definitive Feasibility Study (“DFS”) in Q3 2025.

Zeotech, Chief Executive Officer, James Marsh commented:

“We are excited by the positive outcomes of the AusPozz™ Project PFS, which presents a compelling business case for establishing Australia’s first manufacturing facility dedicated to producing a world-class high-reactivity metakaolin. This advanced supplementary cementitious material (“SCM”) product offers both significant environmental and technical benefits, making it a key enabler in accelerating the transition to low-carbon concrete across a broad range of applications.”

“AusPozz™ is well-positioned to become a game changer in Australia’s building and construction materials sector, with the potential to make a substantial contribution to the nation’s net-zero carbon emission targets. We eagerly look forward to advancing the DFS and continue driving sustainable innovation.”

BACKGROUND

Zeotech has completed its AusPozz™ PFS, which aimed to deliver a robust business case for the Company’s high-reactivity metakaolin product, AusPozz™. The PFS evaluated the technical and financial viability of AusPozz™ and Kaolin DSO, utilising its ultra-high purity kaolin from the Toondoon Kaolin Project (“Toondoon”) in Queensland.

AusPozz™ is a low-carbon SCM primarily targeting cement replacement in the domestic building materials market and potential export opportunities. The proposed AusPozz™ Manufacturing Facility is intended to be located at the Port of Bundaberg, Queensland.

The AusPozz™ Manufacturing Facility is proposed to comprise a single initial train with a nameplate capacity of 300,000 tpa. The Toondoon Kaolin Deposit will provide all kaolin ore required for the AusPozz™ Manufacturing Facility and export of Kaolin DSO products. Production targets for Kaolin DSO and Cosmetic Kaolin DSO products are 142,000 dtpa and 9,000 dtpa, respectively.

The projected LOM is 20 years for the Project, and the financial analysis and overall economics of the Project have been completed with an accuracy expected to be +/- 25%.

A summary of the key AusPozz™ Project parameters is summarised in Table 1 .

The Project’s lifecycle analysis (“LCA”) presents the potential of a substantial ongoing reduction of embodied carbon in the built environment, resulting from 1-for-1 replacement of cement with AusPozz™ in low-carbon concrete. At nameplate production, it could reduce carbon emissions by an estimated 229,800t CO₂-e per annum. This is the equivalent[3] of:

  • Cars Off the Road: taking about 53,600 petrol-powered cars off the road yearly.

  • Tree Planting: planting each year and growing approximately 3.8 million tree seedlings for 10 years.

  • Energy Use: annual carbon emissions from electricity use in over 30,860 homes.

NEXT STEPS

The AusPozz™ Project PFS presents a compelling case for Zeotech’s entry into the SCM market through the development of a vertically integrated operation. Independent concrete trials confirm that AusPozz™ delivers a superior SCM product with a range of technical advantages.[4]

The PFS demonstrates that the Project is technically feasible, economically viable, and strategically aligned with sustainability in the built environment, driven by domestic and global decarbonisation goals, which are accelerating the growing demand for low-carbon SCMs.

Key findings include:

  • Strong Business Case: The PFS confirms that AusPozz™ can be produced efficiently with a light carbon footprint, at low cost and low risk, with robust margins supported by strong market demand evident in the domestic construction and infrastructure sectors.

  • High-Quality Resource : The Toondoon Kaolin Deposit is confirmed to be of ultra-high purity, with a kaolinite content > 90% in the ore clays, making it ideal for Kaolin DSO, Cosmetic Kaolin DSO, and economic AusPozz™ production.

  • Scalable Production: Proposed nameplate 300,000 dtpa AusPozz™ Manufacturing Facility at the Port of Bundaberg is well-supported by infrastructure, logistics, utilities, and offers the potential for future Train 2 expansion.

  • Market Readiness: The Company has a growing sales/specifier opportunity pipeline of 65 active leads and has secured early MOUs with major industry players, including Holcim[5] for AusPozz[TM] and MSI[6] for Kaolin DSO products.

  • Environmental and Social Alignment: The Project aligns with sustainability goals by offering a high-performance, low-carbon alternative to traditional cement, offering the potential to deliver a significant ongoing contribution to decarbonisation within the Australian built environment, while also supporting regional employment and community development.

  • Execution Pathway: A clear roadmap has been established, with a DFS scheduled to commence in Q3 2025, leading to Final Investment Decision (“FID”) in Q1 2026 and full AusPozz[TM] production achieved by Q1 2029.

AusPozz™ has the potential to transform the domestic building and construction materials sector, making a positive and ongoing contribution to Australia’s Net-Zero carbon emission goals.

The Company has commenced planning for the transition to a DFS, which is scheduled to begin in Q3 2025. The DFS will refine technical, regulatory, and commercial aspects, including:

  • Conducting further drilling to expand and upgrade the Toondoon Kaolin Resource and feasibility-level assessments to address outstanding Modifying Factors and support future Ore Reserve estimation.

  • Finalising environmental approvals and regulatory submissions.

  • Optimising mine planning and conducting advanced geotechnical studies.

  • Undertaking comprehensive vendor(s) plant and equipment trials.

  • Completing engineering design and securing utility agreements.

  • Executing binding offtake agreements supported by customer trials.

  • Completion of the Port of Bundaberg site agreement(s), including storage options.

  • Evaluating expansion or duplication of production trains that could increase AusPozz™ output and support the Company’s Horizon 2 initiatives.

Horizon 2 initiatives involve the development of high-value downstream products utilising highreactivity metakaolin feedstock to produce manufactured zeolites.

Horizon 2 opportunities under advanced development include:

  • zeoteCH₄®: A proprietary zeolite formulation designed to eliminate landfill methane emissions.[7]

  • Animal Feed Supplements: Offtake associated with a zeolite-based supplement aimed at preventing subclinical hypocalcemia, also known as milk fever, in cows.[8]

This announcement has been approved by the Zeotech Board.

Cautionary Statement

The PFS referred to in this announcement has been undertaken to assess the technical and economic viability of the AusPozz™ Project. The study aims to identify the preferred mining, processing, and infrastructure requirements, but it is not final. Further evaluation work, including a Definitive Feasibility Study (DFS), is required before the Company can provide assurance of an economic development case.

This PFS is more than a preliminary technical and economic study given the work undertaken for the study, but it is not advanced sufficiently to support the estimate of Ore Reserves, and further technical work, including additional drilling and feasibility-level assessments, is planned to resolve the outstanding Modifying Factors and support a future Ore Reserve classification or provide any assurance of an economic development case .

The Production Target referred to in this announcement is based on this PFS and supported solely by Measured and Indicated resources and not an Ore Reserve. Zeotech has concluded that it has reasonable grounds for disclosing a Production Target; however, there is no certainty that the Production Target or the economic assessment will be realised.

The information in the PFS that relates to metallurgical results and processing assumptions is based on preliminary test work and should not be considered definitive.

Additional test work, including vendor testing, is required to confirm the technical and economic viability of the proposed process flowsheet and product specifications.

The PFS is based on the material assumptions described in the body of this report and summarised in the Summary of Material Assumptions and Summary of Modifying Factors in Appendix 1. These include assumptions about the availability of funding and the pricing received for the Company’s AusPozz™ and Kaolin DSO products. While the Company considers all of the material assumptions to be based on reasonable grounds, there is no certainty that they will prove to be correct or that the range of outcomes indicated by this PFS will be achieved. To achieve the range of outcomes indicated in the PFS, funding in the order of $95m including working capital will likely be required. Investors should note that there is no certainty that the Company will be able to raise the amount of funding when needed.

It is also possible that such funding may only be available on terms that may be dilutive to or otherwise affect the value of the Company’s existing shares. It is also possible that the Company could pursue other ‘value realisation’ strategies such as a sale, partial sale or joint venture of the project. If it does, this could materially reduce the Company’s proportionate ownership of the Project.

Given the uncertainties involved, investors should not make any investment decisions based solely on the results of the PFS.

EXECUTIVE SUMMARY

1. PFS Overview

Project Scope

Zeotech (ASX: ZEO, “Zeotech” or “the Company”) completed this AusPozz[TM] Project Preliminary Feasibility Study (PFS) with the aim of delivering a robust business case for the Company’s highreactivity metakaolin product, AusPozz[TM] .

The PFS evaluates the technical and financial viability of AusPozz[TM] and kaolin direct shipping ore (DSO) products - Kaolin DSO and Cosmetic Kaolin DSO - using its high-purity kaolin from Zeotech’s Toondoon Kaolin Project (Toondoon) Deposit in Queensland.

The financial analysis and overall economics of the Project have been completed with an accuracy expected to be +/- 25%.

The PFS provides the basis for a more detailed Definitive Feasibility Study (DFS) that Zeotech will require to provide assurance for the economic development case of the AusPozz™ Project.

Project Description

  • AusPozz[TM] is a low-carbon pozzolanic supplementary cementitious material (SCM) predominantly targeting domestic construction markets in Eastern Australia and potentially international export markets.

  • The AusPozz™ Manufacturing Facility is proposed to be built and located at Port of Bundaberg, Queensland, on designated Bundaberg State Development Area (SDA) land outlined in a Letter of Intent executed between Zeotech and Gladstone Ports Corporation (GPC).[9]

  • The AusPozz™ Manufacturing Facility is proposed to comprise a single train with a nameplate capacity of 300,000 dry tonnes per annum (dtpa), scheduled to be commissioned approximately 36 months after the commencement of the Project.

  • The Toondoon Mine Site will provide all kaolin ore for the AusPozz™ Manufacturing Facility and export of Kaolin DSO and Cosmetic Kaolin DSO products. The projected life of mine (LOM) for the Project is 20 years.

  • Zeotech has signed a memorandum of understanding (MOU) with Holcim Australia for AusPozz[TM] concrete pilot trials and potential offtake agreements.[10]

  • Additional Kaolin DSO and Cosmetic Kaolin DSO products are planned, with production targets of 142,000 dtpa and 9,000 dtpa, respectively.

Cultural Heritage

A search of the cultural heritage database and register for the Toondoon Area and the proposed AusPozz™ Manufacturing Facility Area was undertaken. No records of Aboriginal or Torres Strait Islander cultural heritage sites were found for ML 80126, EPM 27866, or the proposed Facility Area. Six cultural heritage sites were identified near the western boundary of EPM 27395.

The Company, with legal support, plans to engage with the Auburn Hawkwood People to develop a cultural heritage management plan or agreement, including conducting a cultural heritage survey for the Toondoon Area.

Native Title

Native Title for ML 80126 is extinguished due to the grant of freehold tenure. The Auburn Hawkwood People have a current Native Title Claim Determination over parts of the broader Toondoon Area. In areas where Native Title has not been extinguished, Zeotech will comply with the Native Title Act.

The proposed AusPozz™ Manufacturing Facility Area (Port of Bundaberg) is on Bundaberg SDA freehold land, and Native Title has been extinguished.

3. Legal, Regulatory, and Policy

The AusPozz™ Project is being developed in compliance with the applicable legal and regulatory frameworks of Queensland and the Commonwealth. Key approvals and compliance obligations include:

  • Environmental Protection Act 1994 : An Environmental Authority (EA) is required for mining and processing activities. ML 80126 currently operates under a Standard EA, with a site-specific EA expected as the Project expands.

  • Aboriginal Cultural Heritage Act 2003 : Activities will be conducted in accordance with the cultural heritage duty of care, regardless of land tenure or register status.

  • Planning Act 2016 and State Development and Public Works Organisation Act 1971 : The proposed AusPozz™ Manufacturing Facility, located in the Bundaberg SDA, requires SDA approval from the Coordinator-General.

  • Water Act 2000 , Vegetation Management Act 1999 , and other environmental laws govern water use, vegetation clearing, and land access.

  • National Greenhouse and Energy Reporting Act 2007 : Zeotech will report emissions in accordance with NGER thresholds.

  • Native Title Act 1993 : The Auburn Hawkwood People will be engaged where Native Title has not been extinguished.

The project aligns with the Equator Principles (EP4) 2020 and is classified as a Category B Project, with limited, site-specific environmental and social impacts (EP Guideline specification).

4. Geology and Mineral Resources

Geological Setting

The Toondoon Area is situated within Queensland’s Surat Basin and features a geological profile that consists of Jurassic Evergreen Formation, overlain by Tertiary sediments.

The weathered surface is capped by pisolitic-bauxitic clays that overlie alumina-rich plastic clay, high-iron and low-iron white kaolinite clays, and a basal sandy clay layer - all of which are economically relevant for the AusPozz™ Project.

Exploration and Drilling

Between 2012 and 2025, four drilling campaigns were conducted, utilising air-core, reverse circulation (RC), and diamond drilling methods. A total of 117 drillholes - comprising 94 air-core holes, 16 reverse circulation (RC) holes, and 7 large-diameter 4C core holes - were completed, contributing 3,088.6m of drilling data that inform the Mineral Resource Estimate (MRE).

In 2025, Zeotech conducted trench sampling and a drilling program, which provided updated dry bulk density (DBD) data and enhanced geotechnical insights, thereby improving the accuracy of the 2025 MRE.

Sampling and Sub-sampling

All drillholes from the main drilling program completed in 2021 were sampled at 1.0 m intervals. All samples were dry and were split onsite using an 87.5:12.5 splitter (comprising three sets of riffles). The 87.5% fraction samples were retained. The 12.5% fraction was further split with a 50:50 splitter to produce an approximate 300 g sample for analysis.

Analysis

All samples from the 2021 program were prepared and analysed at the ALS Group laboratory in Queensland. The clay samples were weighed and pulverised to a nominal -75 µm. The mill was cleaned with a silica sand flush after each sample.

Pulverised samples were analysed by X-ray fluorescence (XRF) method ME-XRF13n used typically to analyse bauxite samples. A 0.7 g fused disc was analysed and reported whole metal oxides (with detection limits) for Al ₂ O ₃ (0.02%), BaO (0.01%), CaO (0.01%), CoO (0.01%), Cr ₂ O ₃ (0.002%), Fe ₂ O ₃ (0.01%), K ₂ O (0.002%), MgO (0.01%), MnO (0.002%), Na ₂ O (0.01%), P ₂ O ₅ (0.002%), SiO ₂ (0.05%), SO ₃ (0.005%), SrO (0.001%), TiO ₂ (0.004%), V ₂ O ₅ (0.001%), Zn (0.001%), and ZrO ₂ (0.002%).

A Loss-on-Ignition (LOI) analysis using ALS method ME-GRA05 was used to determine the amount of hydroxyl water in the clay minerals.

Quality Assurance/Quality Control

  • Quality Assurance/Quality Control (QA/QC) protocols were implemented during sampling and analysis.

  • An Independent Technical Specialist Report completed by Derisk[12] validated the geological model and resource estimation approach used in the 2022 MRE and recommended additional DBD data collection, which was completed in 2025.

In January 2022, Ausrocks prepared a MRE for Toondoon using all data from the 2021 drilling programs. The process used by Ausrocks comprised the following steps:

  1. Digital files of drillhole data were imported into Micromine software for checking and validation.

  2. Digital survey data of the topography was imported into Micromine as collected from a drone photogrammetry survey and reviewed.

  3. Data validation checks were completed, focused on errors or inconsistencies in the drillhole collar and assay data.

  4. QA/QC data was reviewed.

  5. 3D interpretations of lithology and clay horizons were created based on the drillhole logs and assays. Five lithologies were interpreted – bauxitic clay, plastic clay, kaolinite clay (high iron), kaolinite clay (low iron) and sandy clay. The contact between the base of the low-iron kaolinitic clay and the top of the sandy clay horizon was guided by using a criterion of 32% Al2O3 and 47.5% SiO2.

  6. Statistical analysis of drillhole geochemical data was completed.

  7. Drillhole composite lengths were selected, followed by composite statistics and a variographic analysis of the drillhole data.

  8. A 3D block model was created (10 mE x 10 mN x 1 mRL), with sub-celling of parent blocks (1 mE x 1 mN x 1 mRL) to allow reasonable boundary definition to honour topography and geological features.

  9. Estimation search parameters were developed, and estimates were generated using the ordinary kriging (OK) method.

  10. Average DBD estimates of 2.05 t/m[3 ] were applied to bauxitic clay, 1.74 t/m[3 ] for plastic clay and kaolinite clay, and 1.69 t/m[3 ] for sandy clay.

  11. Grade estimates were checked visually against the input data. Statistics for kriged estimates and a check estimate using the inverse distance weighting method was completed, together with swath plots.

  12. Assignment of the Mineral Resource classification was completed, considering the confidence in the geological interpretation of the mineralisation, drillhole spacing, and estimation quality. Ausrocks classified the Mineral Resource into Measured, Indicated and Inferred categories.

Geological Model and Domaining

The key inputs to the 2022 MRE comprised the geological logging and geochemical analyses derived from the 2021 drilling programs merged with the digital surface topography data.

Geological interpretation indicates that the plastic clay, kaolinite clay, and sandy clay sequence is folded into a series of northeast trending domal anticlines with associated synclines. The amplitude and frequency of the folded structures decrease away from the outcropping bauxitic clays to the southeast.

3D interpretations of lithology and clay horizons were created based on the drillhole logs and assays. Five domains based on lithologies were interpreted – bauxitic clay, plastic clay, kaolinite clay (high iron), kaolinite clay (low iron) and sandy clay. The contact between the base of the lowiron kaolinitic clay and the top of the sandy clay horizon was guided by using a criteria of 32% Al2O3 and 47.5% SiO2.

Variography

Ausrocks completed a variography analysis of the data and used the results of this assessment to inform an OK estimate of all grade parameters.

As would be expected variography generated very short ranges in the vertical orientation and ranges of several hundreds of metres in the horizontal orientation.

Estimation

The resource model was created using a parent cell size of 10 m (east-west), 10 m (north-south), and 1 m (vertical), with sub-celling of 1 m by 1 m by 1 m respectively. Ausrocks estimated all analysed elements by OK using the variography completed for Al2O3. An Inverse Distance Weighted (IDW) estimate was also completed and used as a check of the OK model.

Figure 5 presents a cross section through the deposit illustrating the drillholes, geological interpretation, and Al2O3 grade distribution as modelled by Ausrocks.

Validation

Ausrocks validated the model by visually assessing drillhole grades against the estimated model grades, and by preparing Swath plots of the drillhole data and block model for Al2O3, Fe2O3, SiO2, TiO2, and LOI grades, which showed sufficient spatial correlation between estimates and input drillhole grades. Ausrocks also compared the OK estimate with the IDW estimate.

Resource classification used the following criteria:

  • Measured Resource: Drillholes had to show geological continuity between gridded drillholes with a confirmatory spacing (100 m x 100 m with infill holes with a minimum of one hole drilled within each 4 x 100 m drillhole ‘square’).

  • Indicated Resource: Drillholes had to show geological continuity between gridded drillholes with a spacing of 100 m x 100 m.

  • Inferred Resource: Drillholes had to show geological continuity between gridded drillholes with a spacing of 100 m x 100 m but where there was limited cross sectional control (only 2 or 3 drillholes in cross section).

A plan showing the Resource classification is presented in Appendix 7 .

DBD Assumptions

For the 2022 estimate, Ausrocks used DBD estimates of 2.05 t/m[3] for bauxitic clay, 1.74 t/m[3 ] for plastic clay and kaolinite clay, and 1.69 t/m[3 ] for sandy clay.

Modifying Factors

The Competent Person for the 2022 Mineral Resource estimate reviewed the clay characterisation studies completed to date, as well as potential mining, processing, and marketing options to demonstrate that there are reasonable prospects for eventual economic extraction.

AusPozz[TM] Project Preliminary Feasibility Study (PFS)

Page 16

==> picture [150 x 43] intentionally omitted <==

The Mineral Resource was reported using the cut-off criterion of 23% Al2O3 for the sandy clay horizon and 32% Al2O3 for the kaolinite clay. No cut-off was used for the remaining two clay horizons after considering plausible mining, processing, and economic parameters.

Updated June 2025 Mineral Resource Estimate

The 2022 MRE was externally reviewed in 2022 when Zeotech engaged Derisk to prepare an Independent Technical Specialist Report of the Project. Derisk identified a key limitation in the 2022 MRE, namely the insufficient spatial and vertical distribution of dry bulk density (DBD) measurements across the deposit.

In response, Zeotech completed the 2025 DBD measurement program to rectify the lack of measurements identified by Derisk. The rationale for updating the previous 2022 MRE to the June 2025 MRE for the Toondoon Kaolin Deposit is grounded in several key technical and methodological improvements following data obtained from the 2025 drilling program.

A comprehensive commentary that presents the rationale is detailed in Table 4 .

Further details regarding the drilling, sampling, assaying, estimation methodology, and classification criteria used in the June 2025 Mineral Resource Estimate are provided in Appendix 3 – JORC Code 2012 Edition Table 1 .

Zeotech has prepared an updated (June 2025) MRE for the Toondoon Kaolin Deposit as part of the PFS. The Competent Person for the Mineral Resource estimate has reviewed the data from both 2022 and 2025 and has concluded that revised DBD estimates of 1.66 t/m[3] for bauxitic clay, 1.46 t/m[3 ] for plastic clay, 1.42 t/m[3 ] for high iron kaolinitic clay, 1.44 t/m[3 ] for low iron kaolinitic clay, and 1.65 t/m[3 ] for sandy clay should be used for reporting an updated MRE.

The June 2025 MRE supports a 20-year LOM and underpins the Project’s production targets. The June 2025 MRE updates the 2022 MRE, has been prepared in accordance with the JORC Code (2012), and incorporates new drilling and the DBD data collected in 2025.

Comparison of June 2025 Mineral Resource Estimate with 2022 Mineral Resource Estimate

A comparison of the Measured, Indicated and Inferred Resources reported in the June 2025 MRE for the Toondoon Area incorporating the new drilling data and revised DBD measurements of the various ore types is presented in Table 5 .

Summary

The update from the 2022 MRE to the June 2025 MRE was driven by the need to improve the accuracy and reliability of the tonnage and grade estimates, particularly through enhanced DBD data. The 2025 drilling campaign provided core samples that enabled direct DBD testing using three different types of measurements, revealing that previous estimates were likely overestimated due to reliance on surface grab samples.

This update aligns with best practices in resource estimation and directly addresses concerns raised in the 2022 external review. The improved data quality supports the continued classification of resources into Measured, Indicated, and Inferred categories, providing a more defensible basis for future mine planning and feasibility studies.

5. Environment

Environmental context, regulatory requirements, and potential impacts associated with the Project were considered for the Toondoon Mine Site and the proposed AusPozz™ Manufacturing Facility at the Port of Bundaberg.

Environmental Approvals

  • The Toondoon Mine Site currently operates under a Standard Environmental Authority (EA).

  • A site-specific EA and Progressive Rehabilitation and Closure Plan (PRCP) will be required as the Project scales.

  • The AusPozz™ Manufacturing Facility will require an SDA approval and an EA for Environmentally Relevant Activities (ERAs) such as fuel burning, mineral handling, and crushing.

Climate and Environmental Setting

  • The Project areas have a subtropical climate with distinct wet and dry seasons.

  • The Toondoon Area is characterised by gently undulating terrain, low erosion risk, and non-acid forming soils.

  • The Port of Bundaberg site is low-lying coastal land, with potential for acid sulphate soils in some areas.

Flora, Fauna, and Ecology

  • The Toondoon Area includes non-remnant vegetation with adjacent remnant ecosystems.

  • Several Matters of National and State Environmental Significance (MNES/MSES) have been identified, including threatened species and ecological communities.

  • The Port of Bundaberg site is largely cleared but mapped as potential shorebird habitat.

  • Groundwater-dependent ecosystems (GDEs) exist near the Mine Site but are not within the ML.

Hydrology and Water Management

  • The Toondoon Mine Site lies within the Burnett River catchment, with no mapped springs or high-risk flood zones within the ML.

  • Effective surface and groundwater management will be crucial to prevent contamination and ensure sustainable use.

Acid and Metalliferous Mine Drainage (AMD)

  • A site-specific investigation into AMD potential has been conducted for the Toondoon Area (Ardent Group Pty Ltd, 2023).

  • The study included the testing of 23 samples (plus two quality control samples), as well as an assessment of the quality characteristics of the topsoil.

  • Preliminary results indicate that the risk of AMD is very low. The quality characteristics of the topsoil were assessed as suitable for use in rehabilitation, with no amendments necessary to reach the proposed post-mining land use outcome of native ecosystem.

AusPozz[TM] Project Preliminary Feasibility Study (PFS)

Page 20

==> picture [150 x 43] intentionally omitted <==

Greenhouse Gas Emissions

  • Estimated annual emissions: 56,788 tonnes of CO₂-equivalent (tCO₂-e), primarily resulting from diesel consumption and natural gas use for calcination.

  • Zeotech will report under the National Greenhouse and Energy Reporting (NGER) Act.

  • Mitigation strategies applying an “Avoid, Reduce, Substitute” hierarchical framework is planned to be implemented, including for energy efficiency, renewable energy options, and emissions monitoring.

Potential Environmental Impacts

  • Key risks include vegetation clearing, dust and noise, erosion, and water quality impacts.

  • • Environmental controls will be implemented through design, monitoring, and management plans.

6. Community and Stakeholder Engagement

Zeotech has undertaken a comprehensive assessment of community and stakeholder engagement as part of the PFS. This evaluates the social and reputational landscape, identifies key stakeholders, and outlines the Company’s approach to building trust, acceptance, and longterm support for the Project.

The Social and Reputational Risk Assessment (SRRA) conducted for the PFS found no significant indicators of community or stakeholder opposition. There are clear opportunities for Zeotech to align with regional development priorities, particularly those outlined in the NBRC’s Advocacy Plan 2024–2028 and the Bundaberg Regional Council’s (BRC’s) economic development strategies.

Zeotech has proactively engaged with key stakeholders, including:

  • Queensland Government Departments of State Development, Infrastructure and Planning (DSDIP) and TMR

  • GPC

  • NBRC

  • Wide Bay Burnett (WBB) Resource Group.

These engagements have been constructive, with strong in-principle support for the Project’s objectives, including the development of the AusPozz™ Manufacturing Facility within the Bundaberg SDA.

The Company has identified potential social risks such as:

  • Increased traffic

  • Workforce competition

  • Housing availability

  • Environmental concerns, particularly around dust and land use.

However, these are balanced by significant opportunities, including:

  • Local employment

  • Supporting local businesses

  • Infrastructure upgrades

  • Community investment.

Zeotech’s commitment to local procurement, training, and partnerships with educational institutions positions the Project to deliver meaningful regional benefits.

AusPozz[TM] Project Preliminary Feasibility Study (PFS)

Page 21

==> picture [150 x 43] intentionally omitted <==

The SRRA also highlights the importance of engagement with Traditional Owners, including the Auburn Hawkwood People, and the need for culturally appropriate heritage management.

Zeotech is well-positioned to build a strong social licence to operate. Through early and ongoing engagement, alignment with regional priorities, and a commitment to responsible development, the Company aims to deliver a project that is not only economically viable but also socially and environmentally sustainable.

7. Mining

The Project will mine a shallow, flat-lying high-grade kaolin resource using a conventional openpit mining operation from the Toondoon Mine Site. The operation is designed for a 20-year LOM, delivering approximately 9.28 million dry tonnes (Mdt) of kaolin ore to the Port of Bundaberg for processing into AusPozz[TM] or for direct shipping.

Mineral Resource

June 2025 total Mineral Resource of 20.36 Mt comprise 10.87 Mt of plastic and kaolinite clays classified as Measured and Indicated Resources containing high alumina and low impurities as shown in .

Importantly, the Mine schedule is based solely on Measured and Indicated Resources. Inferred Mineral Resources were excluded from the production target and do not contribute materially to the Project economics or viability (refer to Appendix 6 for further details).

The rationale for updating the previous 2022 JORC Mineral Resource estimate for the Toondoon Kaolin Deposit is outlined in Section 4 - Table 4 .

Product Streams

There are three mine product streams with the following production across the LOM:

  • Kaolin DSO (low-iron):

  • Kaolin DSO (low-iron): 2.87 Mtdry.

  • • Cosmetic Kaolin DSO (high-iron): 0.18 Mtdry.

  • AusPozz™ Feed 6.23 Mtdry (74% plastic clay, 26% high-iron clay). Total 9.28 Mtdry

Mine Design

  • Based on the Mine design the final pit will be approximately 2,000 m long by 600 m wide with a maximum depth of 30 m.

  • Pit optimisation was undertaken to reflect the production schedule and feedstock constraints.

  • Conservative slope angles (18°–26°) with staged development.

  • No drilling or blasting required; ore is ripped and loaded using graders and front-end loaders (FELs).

Operations

  • Mining is scheduled to start in Q1 2026.

  • Initial production focuses on Kaolin DSO and Cosmetic Kaolin DSO, and AusPozz™ kaolin ore feed stockpiled until AusPozz[TM] Manufacturing Facility commissioning.

  • Dry hire model assumed for equipment; eight site personnel at full operations required, excluding haulage and maintenance contractors.

AusPozz[TM] Project Preliminary Feasibility Study (PFS)

Page 22

==> picture [150 x 43] intentionally omitted <==

Environmental & Regulatory

  • Progressive backfilling and revegetation with rehabilitation integrated into operations.

  • First rehabilitated area to be returned to grazing within 18 months.

  • Site-specific EA to be obtained as the project scales.

Infrastructure

  • Mine services compound includes a weighbridge, on-site laboratory, workshop, and utilities.

  • New access roads and upgrades to Jankes and Myola Roads are planned.

8. Processing Testwork and Ore Characterisation

Comprehensive testwork and analysis were undertaken to validate the suitability of Toondoon kaolin clays for producing Kaolin DSO, Cosmetic Kaolin DSO, and AusPozz™ products. The PFS outlines the mineralogical and chemical characteristics of the resource, the results of extensive laboratory and pilot-scale testwork, and the rationale behind the selected processing technologies.

Ore Characterisation

  • Three primary kaolin domains (plastic clay, high-iron kaolinite, low-iron kaolinite) contain >90% kaolinite. This is an improvement on the previously reported kaolinite content of between 80-90%[13] .

  • The justification for updating the kaolinite content in Toondoon ore clays to >90%, in accordance with JORC (2012) guidelines, is based on a more accurate understanding of thermal analysis data presented in the CQU report[14] , coupled with additional methods of indirectly determining kaolinite content based on mineralogical and chemical data completed for the PFS[15] .

  • A comprehensive rationale supporting this update is presented in Appendix 4 .

  • Updated 2025 DBD and moisture data confirm suitability for processing and transport.

  • The low-iron kaolinite is suitable for high-value DSO markets (e.g., ceramics, paints, catalysts), high-purity high-iron kaolinite with light-pink colouring is suitable for the highvalue DSO cosmetics market.

  • The plastic and high-iron kaolinite clays have high alumina content of >35% Al₂O₃, iron content <5% Fe2O3 and low quartz impurities, making them ideal for calcination and conversion into high-reactivity metakaolin.

  • These kaolinite clays are targeted for AusPozz[TM] production due to their excellent pozzolanic reactivity when converted into metakaolin.[13]

AusPozz™ Production

  • Testwork conducted by Central Queensland University (CQU)[13] and pilot-scale production runs have confirmed that Toondoon kaolins can be effectively calcined at 700–800°C to produce metakaolin with superior reactivity.

AusPozz™ Product Performance

  • Mortar and concrete trials[16] demonstrated that AusPozz™ significantly enhances compressive strength, reduces shrinkage, and improves durability compared to traditional SCMs like Fly Ash and Silica Fume.

  • AusPozz™ meets AS 3582.4:2022 standards for manufactured pozzolans[13] .

  • AusPozz™ gives typical Modified Chapelle Test results[17] of 1,350 mg Ca(OH)₂/g, indicating high pozzolanic reactivity.

AusPozz[TM] Concrete Testing and Applications

  • AusPozz[TM] demonstrated superior strength, reduced shrinkage, and early strength gain suitable for general concrete, shotcrete, precast, and large-volume pours (e.g., wind turbine bases) applications[18] .

  • Early strength gain and reduced thermal differential (cracking risk) support the use of AusPozz[TM] in demanding infrastructure projects.

Process Flowsheet

  • The process flowsheet for AusPozz[TM] production includes mining, transport to the Port of Bundaberg, feed storage, feed preparation, calcination, milling, and packaging or bulk storage ready for transport to the customer ( Figure 6 ).

[TM]

Processing Technology Selection

  • The PFS supports the use of a rotary kiln for drying and calcination.

  • Rotary kiln technology was selected over flash calcination for industrial cost, low process complexity, reliability, ease of operation, and proven performance, due to compatibility with the kaolin’s moisture content and particle size characteristics.

  • A vertical roller mill (VRM) was chosen for energy-efficient post-calcination grinding and resultant product quality to achieve target particle size distribution (D50) of 20 microns.

9. Mineral Processing and Plant Engineering

The AusPozz[TM] Manufacturing Facility is proposed to have a nameplate capacity of 300,000 dtpa production output of AusPozz™ (Train 300) from kaolin ore feed, sourced from the Toondoon Mine Site. Train 300 is intended to enter full production in Q1 2029.

In the PFS design, 220,000 dtpa AusPozz[TM ] is sold to customers in bulk, and 80,000 dtpa AusPozz[TM] is sold to customers in 1t bulk bags.

The front-end calcination operation is expected to run continuously, achieving 8,040 operational hours annually with an availability of 92%. The milling circuit is expected to operate slightly less, with 7,600 hours per year, reflecting an availability of 87%.

Intermediate storage has been integrated into the process design between the calcination and milling circuits to manage the difference in availability.

The AusPozz[TM] product bagging operations are scheduled to be conducted five days per week. AusPozz[TM] bulk product can be continually transferred to bulk storage, with shipments anticipated monthly.

Items of note for the AusPozz[TM] Manufacturing Facility covered in the PFS are:

  • Project Design Criteria : Contains key project and process design parameters for the conversion of kaolin ore to AusPozz[TM] .

  • Process Flow Diagrams : Includes the end-to-end process and material flows, and major equipment items and packages.

  • Mass Balance : Key process streams and utilities.

  • Detailed Equipment List : Name and type of equipment itemised with key properties such as capacities, flow rates, dimensions, installed motor power, fixed or variable speed drive and type, draw, and costs through vendor and consultant engagement.

  • Key Equipment :

  • Kaolin feed and preparation.

  • Rotary kiln for drying and calcination.

  • Rotary cooler.

  • VRM circuit.

  • Baghouses for off-gas dust removal and recovery.

  • Product storage and dispatch :

  • Bagging in 1t bulk bags for truck dispatch.

  • Bulk storage and ship loading.

  • Environmental Controls :

  • Dust collection.

  • Compliance with emissions standards.

The process plant operation can be summarised by the following sequential activities:

1. Ore Receival, Handling & Storage

Kaolin ore (plastic clay and high-iron kaolinite) is delivered via side or rear-tipping B- double trucks. A front-end loader (FEL) places the ore into one of two stockpiles based on type. Stockpiles are designed to hold at least seven days of production feed.

2. Feed Preparation

Blending of the two kaolin types is controlled by the feed ratio into the feed bins.

3. Drying & Calcination

Kaolin is dried and calcined in a single natural gas rotary kiln. Calcination (700–800°C) removes crystallisation water from kaolinite and converts it to metakaolin. Tail gases flow counter-currently to dry the production feed.

4. Cooling

The product is cooled in a rotating drum using ambient air and lifting flights to enhance heat transfer.

5. Intermediate Storage

Silos provide up to three days of buffer storage.

6. Milling

Coarse AusPozz™ is ground in a VRM to a D50 particle size of 20 microns.

AusPozz[TM] Project Preliminary Feasibility Study (PFS)

==> picture [150 x 43] intentionally omitted <==

7. Product Recovery & Dust Collection

Three baghouse systems recover product and control dust at the kiln feed, cooler, and milling circuit.

8. Packaging & Dispatch

Final product is transferred to a silo for bagging or bulk storage. It can then be dispatched in bulk bags, shipped in bulk, or transferred to dry bulk tankers for customer delivery.

The process plant operation would be supported by services including:

  • Fire-fighting water storage tank, pumps, piping, and fixtures.

  • Potable water supply/storage for human use, safety showers, truck washing, and process water.

  • Natural gas to fuel the kiln burners.

  • Compressed air for both process needs and instrumentation.

  • Reticulated low-voltage and high-voltage electricity to power equipment and buildings.

  • On-site diesel refuelling truck for on-site mobile equipment and vehicles.

10. Infrastructure and Services

Scalable Production

The proposed 300,000 dtpa nameplate capacity AusPozz™ Manufacturing Facility at the Port of Bundaberg is well-supported by infrastructure, logistics, and utilities, with potential for future expansion.

Facility Utilities

Utilities services to meet the AusPozz™ Manufacturing Facility requirements have been assessed. State Government support has been provided for the following utilities required by Zeotech for operations of the Facility in the SDA at the Port of Bundaberg:

  • Gas : Zeotech, supported by State Government Development, is in discussions with Jemena (Queensland Gas Pipeline) and AGIG (Wide Bay Pipeline and Port of Bundaberg Pipeline) regarding the expansion of the gas infrastructure needed to meet the requirements of Train 300 and potential future train expansion requirements of the Facility.

  • Electricity : Ergon Energy is the provider to the Port of Bundaberg, and a major customer connection will be required by Zeotech for the Facility.

  • Water : Potable water supply to the Port of Bundaberg is by the BRC, and there is potential to utilise irrigation water supplied by SunWater.

11. Administration and Workforce

Zeotech prioritises local employment at both the AusPozz™ Manufacturing Facility and the Toondoon Mine Site, with a focus on Work, Health and Safety and Fair Work legislation.

The Project represents a significant stable employment opportunity, especially for regional manufacturing in Bundaberg, which traditionally experiences seasonal fluctuations.

At full operation, it is proposed that 52 personnel will be employed at the Facility and 21 personnel will be employed at the Mine Site. Additionally, 56 contracted haulage personnel are proposed for logistics.

There are expected to be 12 full-time equivalent supporting corporate and administration personnel employed by Zeotech at the Port of Bundaberg and Brisbane Technology Park head office.

Zeotech emphasises inclusive recruitment and training programs.

The Company proposes to outsource mining and haulage operations with dry hire and full-service options considered.

12. Logistics

13. Marketing

Zeotech has secured early commercial interest, validated through MOUs with major industry players, including Holcim Australia for AusPozz[TM] and MSI China for Kaolin DSO and Cosmetic Kaolin DSO. The Company has identified and is engaging with multiple domestic and international sales opportunities across various product lines, as summarised in Table 8 .

AusPozz™ users consist of a tiered structure (Tier 1 and Tier 2, as outlined below) based on the position of the targeted cement producer/supplier customers in the building and construction industry supply chain and their potential offtake volumes.

  • Tier 1 – major cement producers/suppliers;

  • Tier 2 – companies that buy cement from Tier 1 cement producers/suppliers or import directly from offshore cement producers; and

  • Tier 2 – engineering and design companies that play an essential role in specifying AusPozz[TM] in their concrete mix designs for projects they are involved in. This would oblige concrete supply companies to use AusPozz™ for specific applications in dedicated projects.

Market Drivers – AusPozz™

  • Domestic and global decarbonisation mandates.

  • SCM demand due to Fly Ash and Blast Furnace Slag reducing in availability.

  • Combination of low embodied carbon and a range of technical advantages when used to produce low-carbon concrete when compared to alternative SCMs.

  • Continuing growth in domestic construction, in conjunction with the boom in Asia and, more broadly, infrastructure growth globally.

  • Limited access to imported metakaolin to meet growing market demand.

  • No current domestic producer/supplier of metakaolin.

Competitive Advantage – AusPozz™

  • High-reactivity metakaolin with proven properties for improving concrete performance.

  • Low-cost producer due to relatively high kaolinite content in the raw Toondoon kaolin ore.

  • Low carbon footprint due to fewer feed refinements required in processing stages.

  • First domestic commercial-scale producer for the Australian market.

Target Markets

  • AusPozz™ into domestic and international cement and concrete producers (Tier 1 and Tier 2 customers).

  • AusPozz™ small lots business via appointed distributors.

  • Kaolin DSO business into coatings, ceramics, cosmetics, and specialty chemical sectors via mineral traders.

Pricing & Sales Forecast

Targeted pricing by Zeotech for its product portfolio ( Table 9 ) for Kaolin DSO is supported by equivalent commercial product pricing for kaolin and based on the relative high purity of the Toondoon Resource. The Toondoon kaolin characteristics are considered desirable by buyers in an environment where comparable products are becoming increasingly difficult to source.

AusPozz[TM] product pricing takes into consideration relative tiered cement pricing, technical advantages, and carbon reduction benefits when utilised to produce low-carbon concrete.

Table 9: AusPozz™ Project Product Targeted Pricing

Product Price Range (A$/t) Price Range (A$/t) Sales Forecast

Life Cycle Analysis

Zeotech engaged Pangolin Associates to conduct a lifecycle analysis (LCA) for AusPozz™. Pangolin uses a science-based approach to assess the environmental aspects and potential impacts of a product, process, or service by:

  • Compiling an inventory of relevant energy and material inputs and environmental releases.

  • Evaluating the potential environmental impacts of those inputs and releases.

  • Interpreting the results to better inform decision-makers and communicate impact.

The goal of this work was to determine the LCA for AusPozz™ when used as a partial replacement for 30% of cement in concrete applications. The conclusions from this work indicate that AusPozz™ has a carbon footprint of approximately 204 kg CO2-e, based on the given assumptions. This equates to just over a 20% reduction in the total carbon footprint for 1m[3] of a typical 32MPa concrete where AusPozz™ is used to replace 30% of cement.

A 1-for-1 replacement of cement with the name plate AusPozz™ Manufacturing Facility output of 300,000 dtpa of AusPozz[TM] has the potential to avoid carbon emissions by an estimated 229,800 tpa.

For the above AusPozz[TM] calculation this is the equivalent of:

  • Cars Off the Road: taking about 53,600 petrol-powered cars off the road yearly.

  • Tree Planting : planting and growing approximately 3.8 million tree seedlings each year for 10 years.

  • Energy Use: annual carbon emissions from electricity use in over 30,860 homes.

These equivalencies are illustrative only and are based on U.S. average emissions data. Comparisons - such as the number of cars taken off the road, the number of tree seedlings planted, or energy use by homes - can be derived using the U.S. Environmental Protection Agency’s Greenhouse Gas Equivalencies Calculator on the website.

Next Horizon Product – Zeolites

As outlined in the PFS, the second longer-term stage of the AusPozz™ Project (Horizon 2) involves the development of high-value product streams using metakaolin feed to manufacture zeolite. This aligns with Zeotech’s broader mission to deliver innovative solutions that address global sustainability challenges.

Horizon 2 initiatives under advanced development include:

  • zeoteCH₄® : A proprietary zeolite-based formulation designed to reduce landfill methane emissions.

  • Animal Feed Additive : A zeolite-based supplement aimed at preventing subclinical hypocalcemia, also known as milk fever, in cows.

Due to strong perceived market demand for AusPozz[TM] , the full capacity of the initial 300,000 dtpa (Train 300) in the PFS has been fully allocated for potential offtake agreements for SCM applications (Horizon 1).

For this reason, it is proposed that metakaolin required for the commercialisation of zeolite will be catered for in the proposed next AusPozz™ Train (refer to Figure 8 ), which is beyond the scope of the PFS and is planned to be covered in the DFS.

14. Financial

The capital and operating cost estimates are presented in Australian dollars (A$) and are based on prices assessed in Q1 2025. The cost estimates are based on a level of accuracy of +/- 25%. The capital cost estimate for the AusPozz™ Manufacturing Facility has been prepared to a level of completeness and accuracy consistent with an Association for the Advancement of Cost Engineering (AACE) Class 4 estimate.

No allowance for price escalation has been included within the capital cost estimate, as it has been assumed that this will be managed within the current allocated contingency provisions.

An allowance for price escalation of 2.0% per annum has been included in the operating cost estimate. This applies to revenue and all direct operating costs, as well as indirect costs, including mining, transportation, processing, storage, handling, general and administrative costs, and personnel costs.

Price escalation is set at the lower band of the Reserve Bank of Australia’s inflation target range of 2% to 3%.

Capital Cost Estimate

A summary of the PFS total capital cost estimate, including initial capital cost and sustaining capital, is presented in Table 10.

Total (incl. contingency) 32.3 52.4 30.1 114.8 17.4 132.2

The summary shows total initial capital cost of $114.8m, including contingency of $11.6m or 11.3% of the total initial capital cost over the first three years of the Project.

Over the LOM, total capital cost is $132.2m, including sustaining capital of $15.1m and total contingency of $13.9m or 13.5% of LOM capital expenditure.

Mining & DSO Operations

The mining estimate includes all direct costs for mine development, supporting infrastructure, and indirect costs associated with contractors, the Owner’s team, and pre-production operations. Dry-hire mining equipment has been selected for the basis of costing for the PFS as it provides a good first-principles understanding of the mine cost drivers.

The estimate also includes ancillary equipment, such as a service trailer, light vehicles, pumps, lighting, site and services compound accommodation and infrastructure, water and power services.

The estimate includes the cost to form and upgrade local NBRC roads, as well as provide a mine access road to connect the Mine Site with the SCR network.

AusPozz[TM] Project Preliminary Feasibility Study (PFS)

Page 32

==> picture [150 x 43] intentionally omitted <==

The estimate includes the Kaolin DSO storage area and the estimated upgrades and infrastructure for stockpiling the ore at a dedicated area adjacent to the MUC at the Port of Bundaberg.

The estimate includes sustaining capital of 3% per year of initial capital expenditure and a contingency of 15%. The total estimate is $11.9m, including contingency and sustaining capital over LOM.

AusPozz™ Manufacturing Facility

The estimate has been developed from the following project documentation and other inputs:

  • Process Design Criteria and Mass Balance.

  • Process flow diagrams.

  • Preliminary site layout, general arrangement for major equipment, and non-process infrastructure.

  • Mechanical equipment list.

  • Vendor budget pricing quotations for major mechanical equipment.

Estimating Methodology

The estimate has been developed with the requirements of an AACE Class 4 estimate as a key consideration. The estimate was completed to determine the expected cost of the Project for the preferred processing flow sheet. It is suitable for a high-level comparison of alternatives, a more detailed economic evaluation, and a basis for further detailed investigation or rejection of the Project.

The estimation methodology involves using major equipment pricing and then factoring in the remaining direct costs, which requires some measurement of quantities. These quantities are estimated from 3D models, drawings, sketches, and similar projects or studies previously undertaken. Equipment pricing has been sourced from known industry suppliers that can potentially service the Project. Bulk material and labour rates are budgetary. Provisions are allowed for areas where further definition was not possible.

Contracting Strategy

The contracting strategy adopted for the estimate broadly follows an Engineering, Procurement. and Construction Management (EPCM) delivery model and assumes the following approach:

  • Major and minor mechanical and electrical equipment is planned to be procured by Zeotech, with the EPCM Contractor acting on the Company’s behalf, directly from vendors and free issued to site execution contractors for installation.

  • Fabrication contracts are planned to be let by Zeotech, with the EPCM Contractor acting on the Company’s behalf, directly with suitable fabricators.

  • Site work execution contracts, such as concrete, are planned to be let by Zeotech, with the EPCM Contractor acting on the Company’s behalf, directly with suitable contractors based on a ‘horizontal’ packaging strategy.

Sustaining capital

An allowance of $12.4m (excl. contingency) has been made for sustaining capital costs over the operating life of the AusPozz™ Manufacturing Facility of 17 years. Sustaining capital has been assessed at 1% of the total project direct costs. Added to this is the cost to reline the rotary kiln every four years based on vendor advice. This equates to 20.1% of the total project direct costs over the LOM.

A further 15% contingency has been applied to sustaining capital cost.

Operating Cost Estimate

The operating cost estimate was prepared using the project design criteria, mass balance, equipment list, and input from the PBG cost database. The cost areas include:

  • Mining

  • Logistics

  • Processing, comprising:

  • Labour

  • Natural gas

  • Power

  • Fuel

  • Water

  • Maintenance

  • Consumables, and

  • QA/QC.

AusPozz[TM] Project Preliminary Feasibility Study (PFS)

  • Personnel

  • General & Administration

Estimated baseline operating costs for LOM, including contingency allowance, are presented in Table 12 and includes all direct costs to produce the AusPozz™ range of products, and direct costs to mine, transport, store, and handle DSO products.

Indirect costs include personnel and general & administrative costs such as tenement management, corporate, administration, and sales & marketing.

All costs are divided by the 20-year LOM, with the exception of processing costs (AusPozz™ only), which is divided by the approximate operating life of 17 years, to produce the annual average LOM cost.

Figure 9: Summary of LOM operating cost centres

Mining Operating Costs

Mining costs for the Project were estimated based on the mining schedule, assuming a dry hire equipment supply contract. Because of the long project life and simple mining method, it is assumed a mine owner operation with fully maintained dry hire, in which the equipment supplier is responsible for maintenance and availability and is remunerated on an hourly rate usage basis.

Operating costs for grade control, ripping, and load and haul were estimated using equipment operating hours, productivity, labour rates, fuel consumption, maintenance requirements, and consumables.

Total LOM average mine operating costs are $5.46/tdry (excl. contingency) of ore produced.

Mining common and overhead costs include personnel at the Mine Site and the periodic hiring of equipment to support mining activities.

Mining operations are planned to be overseen by a full-time Mine Manager/Site Senior Executive.

Logistics

Haulage of the ore from the Toondoon Mine Site to the AusPozz™ Manufacturing Facility and DSO Storage Area is intended to be contracted to trucking company(ies). Logistics costs have been developed based on modelling and quotes from the logistics companies following a formal request for quotation (RFQ) process.

Processing Costs

The Facility operating labour costs were developed from a schedule of required labour prepared by Zeotech in collaboration with vendors and Pitch Black Group (PBG), with costs for each labour resource obtained from industry sources. The costs include the basic salary with a 21.4% payroll burden per position.

The cost of natural gas was evaluated in consultation with two energy providers, and discussions with the gas pipeline owners, Jemena for the Queensland Gas Pipeline (QGP) and Australian Gas Infrastructure Group (AGIG) for the Wide Bay Pipeline (WBP) and Port of Bundaberg Pipeline (PBP). The consumption rate of natural gas is 2.0 GJ/t of metakaolin, advised by equipment vendors based on the proposed plastic clay and high-iron kaolinite AusPozz[TM] feed blend.

AusPozz[TM] Project Preliminary Feasibility Study (PFS)

Page 36

==> picture [150 x 43] intentionally omitted <==

The cost of power was evaluated in consultation with two energy providers. The power demand was derived from the equipment list, based on all normally operating equipment. Allowance was made for absorbed power by applying load factors to the actual installed motor kilowatts.

Maintenance costs for each plant area were estimated as a percentage of the total installed cost, based on complexity, type of equipment, and process conditions in each area. The percentages were sourced from vendors and PBG. The maintenance cost estimate covers lubricants, wear parts, and other smaller replacement items, but excludes parts required for major shutdowns, which are captured under Sustaining Capital.

Storage & Handling

Storage and handling costs have been developed based on an operating flowsheet and estimated costs using equipment operating hours, productivity, labour rates, conveyor rates, port charges and fuel consumption.

Based on discussions with GPC, costs associated with AusPozz™ and Kaolin DSO storage and handling assume a two-part structure comprising a fixed cost for the storage area, together with a variable cost for in-loading (receiving) and out-loading (dispatching) the products.

General & Administration

General & Administration (G&A) personnel include all personnel who are not directly involved in operations at the Toondoon Mine Site or AusPozz™ Manufacturing Facility. G&A personnel have been split into three phases:

  • Phase 1 (Year 1) – DSO operations and AusPozz™ Manufacturing Facility detailed design and procurement.

  • Phase 2 (Year 2-3) – DSO operations and AusPozz™ Manufacturing Facility construction and commissioning.

  • Phase 3 (Year 4+) – Operational phase, including DSO and AusPozz™ Manufacturing Facility operations at nameplate capacity.

All personnel costs include a 21.4% payroll burden per position for items such as superannuation, payroll tax, workers’ compensation, mental health levy, long service leave, and annual leave loading.

Administration costs for the Project have been developed over the three phases based on past actual expenditure and anticipated future expenditure.

Administration costs include:

  • Office administration

  • Insurance

  • Occupancy costs at Head Office (Brisbane Technology Park) and the proposed AusPozz™ Manufacturing Facility Area

  • Corporate costs

  • Equipment leasing.

Corporate costs include:

  • Legal

  • Accounting and audit

  • Insurance (Directors & Officers (D&O) insurance)

  • Advisory

  • Director and secretary fees.

Contingency

Contingency has been applied on a scale that reflects the relevant risk and the implemented mitigation strategy associated with the cost component. The average contingency applied across the operating cost estimate is 10.6%.

All-In Sustaining Cost

All-In Sustaining Cost (AISC) has been developed to provide a transparent measure of the total cost of producing the Project’s AusPozz™, Kaolin DSO, and Cosmetic Kaolin DSO products. Kaolin DSO and Cosmetic Kaolin DSO are grouped as ‘DSO’ products. AusPozz™ is differentiated into ‘bulk’ and ‘bagged’ products, based on separate flowsheets and operating expenditures.

AISC encompasses all mining costs, including site administration, royalty payments, and progressive rehabilitation. All processing, storage, and handling costs are included, and common costs are apportioned between bulk and bagged products based on production volumes.

The AISC (including contingency) for Kaolin DSO and Cosmetic Kaolin DSO products is $105.30/tdry. AusPozz™ bulk product has an AISC of $224.80/tdry and AusPozz™ bagged product has an AISC of $231.60/tdry.

Financial Modelling

Revenue

Revenue for the AusPozz™ Project is modelled from two core product streams:

  • AusPozz™ products; and

  • DSO products – Kaolin DSO and Cosmetic Kaolin DSO.

Table 13 outlines the projected volumes over LOM based on dry metric tonnes of product sold, noting that DSO products are sold on a wet-basis with an assumed 10% moisture content.

The Project assumes that for years 1-3 inclusive, only DSO products will be sold. During this time, the AusPozz™ Manufacturing Facility is being constructed and commissioned, with a forecasted production ramp-up scheduled for Q4 of Year 3. From Year 4 onwards, it is assumed that all nameplate production capacity is sold over the remaining 17 years of the Project.

Table 13: Target Product Volume Summary

Product UOM Year 1 Year 2 Year 3 Year 4+ LOM
AusPozz™ Bulk – Tier 1 ktdry - - 25 150 2,575

Financial Summary

The Project’s base case financial assessment has been modelled using the aforementioned capital costs, operating cost estimates, production volumes, and sales prices. The Project's NPV is derived on an after-royalty, and after-tax cashflow at a discount rate of 8.0%.

The financial assessment incorporates the updated Mineral Resource Estimate and a LOM of 20 years.

Key financial parameters are presented in Table 15 . The financial assessment demonstrates that the Project is economically viable and delivers a strong business case. The after-tax NPV8 is $406m and after-tax IRR is 42%, with a payback period of the initial capital cost of 2.1 years.

Table 15: Key Financial Parameters

Financial Metrics Total LOM Total LOM

Revenue A$m 3,385
EBITDA A$m 1,604
Initial Capital Cost A$m 115

SustainingCapital A$m 17
Net Cashflow A$m 1,455 1,014
NPV8 A$m 548 406
IRR % 56 42
Payback Period19 Years 2.1

Project generates profit and positive cashflow from operations from Year 1 from Kaolin DSO and Cosmetic Kaolin DSO operations, as shown in Figure 10 . This supports a lower estimated initial capital requirement of $95m, including all working capital needs associated with the Project.

The Project would provide an undiscounted net operating cashflow of $1,014m over the LOM. Results are reported on a pre-tax and after-tax basis, noting that the Company has $37.6m of accumulated losses to 30 June 2024, reducing taxes payable on future profits, subject to normal tax rules associated with carry-forward losses.

19 Payback period is calculated by dividing total Initial Capital Cost by free cashflow after AusPozz™ Manufacturing Facility is commissioned

Sensitivity Analysis

The impact of several key financial parameters has been modelled to evaluate their effect on Project value and rate of return. The analysis demonstrates that the Project is resilient with expected sensitivity to sales price and operating cost, but highlights the potential opportunities and upside the Project could deliver.

NPV Sensitivity

Sensitivity analysis is outlined in Table 16 below and models the impact on the after-tax NPV of the Project by changing the key drivers of sales price, production volume, capital cost, and operating cost by +/- 30%.

Table 16: NPV Sensitivity Analysis Table

% Change After-Tax NPV (A$m) After-Tax NPV (A$m) After-Tax NPV (A$m)
Sales Price Volume Capital Cost Operating Cost
-30% 158 228 428 528

20% 675 525 383 280
30% 868 584 367 191

The analysis table and spider graph ( Figure 11 ) show that the Project is most sensitive to changes in sale price or operating cost (margin), and more resilient to changes in capital cost items and sales volume. At a 30% reduction in sales price or volume, which extends beyond the level of accuracy of this report, the Project continues to show a positive NPV.

IRR Sensitivity

Sensitivity analysis is outlined in Table 17 below and models the impact on the after-tax IRR of the Project by changing the key drivers of sales price, production volume, capital cost, and operating cost by +/- 30%.

Table 17: IRR Sensitivity Analysis Table

% Change After-Tax IRR (%) After-Tax IRR (%) After-Tax IRR (%)
Sales Price Volume Capital Cost Operating Cost

The analysis table and spider graph ( Figure 12 ) corroborates the NPV sensitivity analysis, which indicates that the Project is most sensitive to changes in the sale price or operating cost (margin), and more resilient to changes in the capital cost and sales volume. At a 30% reduction in sales price or volume, which extends beyond the level of accuracy of this report, the Project continues to show a positive IRR that is greater than 20%.

Project Financing

To achieve the range of outcomes indicated in the PFS, Zeotech estimates that approximately $95 million in funding will be required to support initial capital expenditure and working capital for the AusPozz™ Project. The Company has undertaken a detailed assessment of its funding strategy and confirms that it has satisfied itself of the requirements, and has formed its financial projections and funding assumptions based on reasonable grounds, including:

  • Independent technical and financial inputs from the PFS, including capital and operating cost estimates prepared to AACE Class 4 standards.

  • Market validation through signed MOUs with Holcim Australia and MSI, supporting earlystage offtake interest.

  • Detailed production schedules based solely on Measured and Indicated Mineral Resources, excluding Inferred Resources from the financial model.

  • Sensitivity analysis demonstrating the Project’s resilience to changes in key variables such as sales price, capital cost, and operating cost

  • Engagement with potential funding partners , including equity investors, debt providers, and government agencies.

Zeotech is actively considering a multi-source funding strategy, which may include:

  • Equity capital raising , leveraging the Company’s strong project economics and strategic positioning as Australia’s first domestic metakaolin producer supported by the track record of the Board and Executive team, and proven ability to attract new capital.

  • Debt financing , supported by robust cash flows from early Kaolin DSO sales and a short payback period of 2.1 years.

  • Strategic partnerships or joint ventures , particularly with downstream users of supplementary cementitious materials (SCMs).

AusPozz[TM] Project Preliminary Feasibility Study (PFS)

Page 42

==> picture [150 x 43] intentionally omitted <==

  • Government funding support , including grants or concessional finance aligned with achieving Australian Net-Zero emissions targets and regional development priorities.

The Company believes that these funding pathways are consistent with market practice for projects of this scale and maturity and that it has reasonable grounds to believe that the required capital can be secured on terms that are not materially adverse to existing shareholders.

Zeotech will continue to refine its funding strategy as part of the proposed DFS, including engagement with financial advisors and potential financiers.

15. Ore Reserves

The technical and economic viability of the AusPozz[TM] Project has been assessed in the PFS with all the relevant Modifying Factors considered in accordance with the JORC Code (2012). This includes mining, processing, metallurgical, infrastructure, economic, marketing, legal, environmental, social, and governmental aspects.

An Ore Reserve has not been declared in the PFS due to unresolved mining, processing, and marketing-related Modifying Factors. Specifically for mining - aspects of the mine plan need to be sufficiently defined, processing - aspects of AusPozz[TM] particle size, feed blend and colour need to be optimised, and marketing - binding offtake agreements for AusPozz[TM] and Kaolin DSO products need to be executed, to apply Modifying Factors with the level of confidence required for Ore Reserve classification under the JORC Code (2012).

Importantly, the economic analysis within the PFS is based solely on Measured and Indicated Resources. Inferred Mineral Resources were excluded from the production target and do not contribute materially to the Project economics or viability.

Following completion of the PFS, Zeotech intends to undertake further technical work, including additional drilling and feasibility-level assessments, to resolve the outstanding Modifying Factors and support future Ore Reserve classification.

16. Risks and Opportunities

A comprehensive risk and opportunity assessment, including risk mitigation measures, was conducted for the AusPozz™ Project as part of the PFS. The evaluation was conducted with input from specialists in legal, regulatory, policy, geology, environmental, community engagement, processing, engineering, logistics, marketing, finance, and project delivery.

18. Conclusion

Business Case

The AusPozz™ Project PFS presents a compelling case for Zeotech’s entry into the SCM market through the development of a vertically integrated operation. The study demonstrates that the Project is technically feasible, economically viable, and strategically aligned with sustainability in the built environment, driven by domestic and global decarbonisation goals, which are accelerating the growing demand for low-carbon SCMs.

Key findings include:

  • Strong Business Case: The PFS confirms that AusPozz™ can be produced efficiently with a light carbon footprint, at low cost and low risk, with robust margins supported by strong market demand evident in the domestic construction and infrastructure sectors.

  • High-Quality Resource : The Toondoon Kaolin Deposit is confirmed to be of ultrahigh purity, with a kaolinite content > 90% in the ore clays, making it ideal for Kaolin DSO, Cosmetic Kaolin DSO, and economic AusPozz™ production.

AusPozz[TM] Project Preliminary Feasibility Study (PFS)

Page 46

==> picture [150 x 43] intentionally omitted <==

  • Scalable Production: Proposed nameplate 300,000 dtpa AusPozz™ Manufacturing Facility at the Port of Bundaberg is well-supported by infrastructure, logistics, utilities, and offers the potential for future Train 2 expansion.

  • Market Readiness: The Company has a growing sales/specifier opportunity pipeline of 65 active leads and has secured early Memoranda of Understanding (MOUs) with major industry players, including Holcim Australia[5] for AusPozz[TM] and Jiangsu Mineral Sources International Trading Co. China (MSI)[6] for Kaolin DSO products.

  • Environmental and Social Alignment: The Project aligns with sustainability goals by offering a high-performance, low-carbon alternative to traditional cement, offering the potential to deliver a significant ongoing contribution to decarbonisation within the Australian built environment, while also supporting regional employment and community development.

  • Execution Pathway: A clear roadmap has been established, with a Definitive Feasibility Study (DFS) scheduled to commence in Q3 2025, leading to Final Investment Decision (FID) in Q1 2026 and full AusPozz[TM] production achieved by Q1 2029.

The PFS concludes that the AusPozz™ Project is a strategically significant Australian first manufacturing opportunity for Zeotech to become a leading supplier of economic, highperformance, low-carbon metakaolin SCM.

AusPozz™ has the potential to transform the domestic building and construction materials sector, making a positive and ongoing contribution to Australia’s Net-Zero carbon emission targets.

Next Steps

The PFS confirms the commercial viability of the AusPozz[TM] Project. The DFS will provide the technical, regulatory, and commercial detail required to support an FID and planned to include a focus on the following key next steps:

  • Finalising and lodging submissions for environmental and regulatory approvals.

  • Developing and implementing an Environmental and Social Risk Management System and a Community and Stakeholder Engagement Strategy.

  • Conducting further geotechnical, hydrological, and hydrogeological studies, and commence environmental baseline monitoring at the Toondoon Mine Site.

  • Optimising the mine plan and pit design.

  • Conduct large-scale calcination and milling trials with selected vendors and finalise the engineering design for the AusPozz™ Manufacturing Facility.

  • Completion of the Port of Bundaberg site agreement(s), including storage options.

  • Finalising, with State Government support, utility (gas, power, water) agreements for the AusPozz™ Manufacturing Facility.

  • Confirming logistics infrastructure and haulage contracts.

  • Executing binding offtake agreements for Kaolin DSO, Cosmetic Kaolin DSO, and AusPozz[TM] products supported by customer product trials.

  • Conducting further drilling and feasibility-level assessments to address outstanding Modifying Factors and support future Ore Reserve classification.

  • Conducting a detailed risk review and refining risk mitigation strategies.

The DFS is scheduled to commence in Q3 2025, with completion expected in Q1 2026.

Next Horizon Product – Zeolite

As outlined in the PFS, the second longer-term stage of the AusPozz™ Project (Horizon 2) involves the development of high-value product streams using metakaolin feed to manufacture zeolite. This aligns with Zeotech’s broader mission to deliver innovative solutions that address global sustainability challenges.

Horizon 2 initiatives under advanced development include:

  • zeoteCH₄® : A proprietary zeolite-based formulation designed to reduce landfill methane emissions.

  • Animal Feed Additive : A zeolite-based supplement aimed at preventing subclinical hypocalcemia, also known as milk fever, in cows.

Due to strong perceived market demand for AusPozz[TM] , the full capacity of the initial 300,000 dtpa (Train 300) in the PFS has been fully allocated for potential offtake agreements for SCM applications (Horizon 1).

For this reason, it is proposed that metakaolin required for the commercialisation of zeolite will be catered for in the proposed next AusPozz™ Train, which is beyond the scope of the PFS and is planned to be covered in the DFS.

Summary of Modifying Factors

Criteria Comment
Mineral Resources
The AusPozzTMProject PFS was based on the June 2025 Mineral Resource
Estimate prepared by a Competent Person – Mineral Resources (Graham
Rolfe) that updates the 2022 Mineral Resource Estimate, prepared by
Ausrocks, incorporating the new drilling data and revised DBD
measurements of the various ore types which was completed in 2025.
Site Visits
The Competent Person (Mineral Resources) for the PFS visited the
Toondoon Area (February and March 2025) to supervise the drilling
campaign, sample collection, documentation, and density analysis.

The Competent Person (Processing Test work and Mineral Processing) for
the PFS visited the Toondoon Mine Site and proposed AusPozzTM
Manufacturing Facility site at Port of Bundaberg in February 2025 to
observe mineral behaviour and characteristics during extraction and
handling, and assess the Facility site suitability for the planned production
process.

Specialist consultants site visits in February 2025 included:
o
Ardent (Toondoon Mine Site) to observe drilling and test pit
excavation, and oversight of the installation of a groundwater
monitoring bore for completion of a Groundwater Baseline Study.
o
MineEcoTech (Toondoon Mine Site) to view drill core and
supervising the test pit deeper excavation.
o
Derisk (Toondoon Mine Site access and Facility site at Port of
Bundaberg) - to assess transport route from the Toondoon mine
site to the Facility site.
o
Pitch Black Group (Facility site at Port of Bundaberg) to assess
the Facility site suitability for the planned production process.
Study Status
The PFS has been completed to assess the technical and economic
viability of the AusPozz™ Project. The study considered all relevant
Modifying Factors in accordance with the JORC Code (2012), including
mining, processing, metallurgical, infrastructure, economic, marketing,
legal, environmental, social, and governmental aspects.

The AusPozzTMProject PFS indicates the Project is technically and
financially viable.

The PFS was completed by Zeotech with input from specialist consultants.

Financial modelling completed as part of the PFS shows that the project is
economically viable under current assumptions.
Cut-off Parameters
With kaolinite contents in excess of 90% in the ore clays, a normal kaolinite
grade economic cut-off has not been used. Instead, product quality criteria,
derived from product specifications, were applied for mine scheduling.

These quality criteria were used to evaluate the 1Ha x 5m scheduling blocks
as follows:
o
< 35% alumina or >5% iron = waste
o
≥ 35% alumina and < 0.5% iron = Kaolin DSO
o
≥ 35% alumina and ≥0.5% and < 1.0% iron = Cosmetic Kaolin DSO
o
≥ 35% alumina and ≥ 1.0% iron and < 5% iron = AusPozz™ Feed

The economics of each scheduling ore block were evaluated considering
the following parameters:productprices,operatingcosts, processyield

High-grade kaolin (>90% kaolinite in the ore clays) with low purities
confirmed.

Extensive laboratory and pilot-scale testwork confirmed mineralogical and
chemical characteristics of the resource.

Testwork confirmed calcination at 700-800°C produces high-reactivity
metakaolin.

Mortar and concrete trials demonstrated that AusPozz™ significantly
enhances compressive strength, reduces shrinkage, and improves
durability compared to traditional SCMs.

AusPozz™ meets AS 3582.4:2022 standards for manufactured pozzolans.

Further large-scale vendor trials, feed variability, material flow properties
and product performance studies are planned for the DFS.
Infrastructure
Mine infrastructure includes weighbridge, laboratory, workshop, and
utilities.

The AusPozzTMManufacturing Facility at Port of Bundaberg is well-supported
with access to roads, gas, power, and water.

The Facility utilises existing port infrastructure, including storage sheds and
a multi-use conveyor for shipping.

Utilities to meet Facility requirements have been assessed, and discussions
are in progress for utility agreements.

There is access to a skilled workforce in Bundaberg that could support the
AusPozzTMManufacturing Facility.

The workforce for the Toondoon Mine Site could be sourced from the local
region, within driving distance of Toondoon.
Economic
All project costs have been identified, assessed, and calculated by Zeotech
and in consultation with expert contributors responsible for various sections
of the PFS.

All costs are as of Q1 2025 with an expected level of accuracy of +/-25%
Capital Cost Estimate

Capital cost estimate: $132.2m (including contingency and sustaining
capital LOM).

The capital cost estimate has been prepared to a level of completeness and
accuracy consistent with an AACE Class 4 estimate.

The estimate methodology is to use major equipment pricing and then factor
the remaining direct costs but involving some measurement of quantities.

Equipment pricing has been sourced from known industry suppliers that can
potentially service the AusPozz™ Project. Bulk material and labour rates are
budgetary.

The contracting strategy adopted for the estimate broadly follows an EPCM
delivery model.

The mining estimate includes all direct costs for mine development,
supporting infrastructure, and indirect costs associated with contractors,
the owner’s team, and pre-production operations.

No allowance for price escalation has been included within the capital cost
estimate, as it is assumed that this will be managed within the allocated
contingency.
Operating Cost Estimate

The operating cost estimate was prepared using the project design criteria,
mass balance, equipment list, and input from the expert consultant cost
database

Cost areas include mining, logistics, processing, labour, gas, power, fuel,
water, maintenance, consumables, QA/QC, indirect personnel, and
general & administration.

Utility costs are based on quoted budget prices provided by utility providers.

Transport costs are based on quoted budget prices.

Labour costs have been built up from an organisational structure typical of
a processing facility of this scale and input from expert consultants.

Dry-hire mining equipment has been selected for the basis of costing for the
PFS.

Calculations include escalation of 2.0% p.a. applied to the baseline
operating cost estimate. This applies to revenue and all direct operating
costs and indirect costs. Price escalation is at the low end of the Reserve
Bank of Australia’s inflation target range of 2% to 3%.

Royalties of $1.00/tdry(Government) and $2.00/tdry(Private) are included.
Financial Model

The financial model used to assess the economic viability of the Project has
been prepared by Zeotech using inputs and assumptions detailed in the
PFS.

Project NPV at a discount rate of 8% and IRR indicate strong economic
viability.

Payback period of approximately 2.1 years from commissioning of the
AusPozz™ Manufacturing Facility.

Sensitivity analysis completed by adjusting key model inputs such as sale
price, volume, capital cost, and operating cost by +/- 30%. Analysis shows
resilience to changes in capital cost items and sales volume, and
sensitivity to changes in operating margin (sales price or operating cost).

A variety of funding source options are being actively considered.

Exchange rate of 0.65 (AUD/USD) and 0.60 (AUD/EUR) based on current
and historical settings.
Marketing
MOUs have been signed with Holcim (AusPozz™) and MSI (Kaolin DSO and
Cosmetic Kaolin DSO).

Target markets are:
o
Domestic and international cement and concrete producers (Tier
1 and Tier 2)
o
Ceramics, cosmetics, and specialty chemical sectors.

AusPozz™ ispositioned as a low-carbon SCM with strongmarket demand.

Legal
Kalotech (wholly owned Zeotech subsidiary) holds the Toondoon Area,
including the Mining Lease (80126) and two Exploration Permits for Minerals
(EPM 27395 and EPM 27866).

Kalotech is the owner of the freehold land (Lot 1 SP331858) of approximately
682 hectares, which covers the whole of the ML and overlaps the adjacent
EPMs.

Legal compliance with Queensland and Commonwealth laws confirmed.

Cultural heritage and Native Title obligations acknowledged and managed.
Environmental
A Standard EA is in place for the Toondoon Mine Site.

A site-specific EA and PRCP will be required for Project expansion in the
future.

Environmental impact assessment identified potential risks.

There is a low AMD risk, and the topsoil is suitable for rehabilitation.

Emissions are estimated at 56,788 tCO2-e/year.

Environmental controls include dust suppression, water management, and
progressive rehabilitation.
Social
A comprehensive assessment of community and stakeholder engagement
was undertaken.

No significant community opposition identified.

Engagement with State government departments and regional councils is
ongoing.

Social risks (traffic, workforce competition, housing, environmental
concerns) balanced by employment and economic benefits.

Traditional Owners and further stakeholders to be engaged.

Zeotech intends to develop a Community and Stakeholder Engagement
Strategy in the DFS phase.
Governmental
The Project aligns with regional development priorities and sustainability
goals.

Approvals required include under:
o
Environmental Protection Act
o
Aboriginal Cultural Heritage Act
o
Planning Act
o

o
Water Act
o
Native Title Act.

The Project will be compliant with Equator Principles and NGER Act.

Zeotech intends to develop and implement an Environmental and Social
Risk Management System.
Classification
No Ore Reserve has been declared at this stage due to unresolved mining,
processing, and metallurgical-related Modifying Factors.

The economic analysis within the PFS is based solely on Measured and
Indicated Resources. Inferred Mineral Resources were excluded from the
production schedule and do not materially contribute to the Project
economics or viability.

Further technical work, including additional drilling and feasibility-level
assessments, is planned to resolve the outstanding Modifying Factors and
support future Ore Reserve classification.
Audits or Reviews
A technical peer review of the PFS was conducted by Derisk Geomining
Consultants Pty Ltd (Derisk).
Study Accuracy
The estimates in this PFS have been completed with an accuracy expected
to be +/- 25%.

Criteria
Commentary Competent Professional – Graham Rolfe
Sampling
techniques
Phase 1 & 2:
The only sampling was from the Air Core and Reverse Circulation Hammer Drilling.
The sample was delivered directly from the rig to a cyclone. The total sample was
bagged and split with an onsite riffle splitter, mounted on a 4wd tray-back.
The drill sampling was completed at one metre intervals and split onsite using an
87.5:12.5 splitter (3 sets of riffles). The 87.5% fraction retention samples have been
removed from the drill sites and stored in a Mundubbera storage shed. The 12.5%
fraction was further split with a 50:50 splitter to produce a sample for analyses by ALS.
The remaining split was used for duplicate sampling and kept on the Gold Coast for
further analyses.
The sample number incorporated the hole number and depth e.g.
Sample from hole TDAC 15 and 5-6m depth = TDAC 1516, and
TDRC 108 and 9-10m depth = TDRC10810.
All samples were bagged in plastic bags to reduce the loss of the very fine-grained clay
minerals.
Phase 3 (4C core drill): The 4C drill core was split using a spatula as the clay material
was soft. Samples of up to 4 metres of 40 to 55% of the core were collected and
dispatched for chemical analyses.
Drilling
techniques
ThePhase 1Air Core Drill Program consisting of 42 holes (TDAC 15-56) for 1042.5
metres was completed in February 2021. ThePhase 2Air Core Drill Program
consisted of 52 holes (TDAC 58-107) and TDAC15B and 16B twinning TDAC15 & 16
were completed in November 2021. The air-core program totalled 1475m.
Sixteen reverse circulation hammer holes TDRC 108 to 123 for 373m were drilled on
50m centres on lines 315800mE and 315850mE. At six sites the TDRC holes were
twinned (110 to 121) and TDRC122 twinned the Phase 1 TDAC39. The drill contract
was completed by Associated Exploration Drilling Pty Ltd using a truck-mounted
AusRoc 4000 Multipurpose Rig with a 250/350 psi Sullair Air Compressor.
The air core drill string consisted of 75mm (OSD) x 3-metre length rods with an 85mm
diameter tungsten rotary bit. The clay was drilled using the Air Core Technique. The
TDRC holes were drilled with a 4.5 inch or 115mm hammer.
Phase 3 (4C Core Drill) drilling in February 2025 was completed by Rockhampton
based Depco. Seven holes TD4C 124-130 were drilled for 158.6 metres using the 4C
coring method with a UDR 650 rig and 39.5m of reverse circulation drilling for the
extension of TD4C126 to 60m depth as a water monitoring bore.

The 4C holes were located centrally between 4 previous air core holes, which were
located on a 100m x 100m grid. The 4C core diameter was nominally 10cm. The 4C
core holes were drilled for density measurements and geotechnical evaluation. Hole
TD4C126 was equipped as a water monitoring bore.
Drill sample
recovery
The 12.5% sample split was within 350-500gm, comparable to the theoretical total
weight of 3.3kg i.e. 420gm in the 12.5% split
The compressor air pressure was turned down to 200psi to reduce the loss of the
fines. However, a fraction of the super-fine clay was lost in the updraft from the
cyclone. The Phase 2 drilling used a larger diameter cyclone with a reduced updraft of
the finer fraction.
Logging The drill chips/powder were graphically logged on paper by the Competent Person at
1:100 scale, noting the colour, the pearly sheen of kaolinite, the plasticity of the grey
clay, quartz (sand and silt fraction), and iron content as hematite and
limonite/goethite) and later transferred to an Excel spreadsheet.
All samples from the drilling were logged.
Sub-sampling
techniques and
sample
preparation
The drill samples were consistently powder clay with quartz as sand and silt size
fractions.
The drilling was completed dry. The drill sampling was at one-metre intervals and split
onsite using an 87.5:12.5 splitter (3 sets of riffles). The 87.5% fraction retention
samples have been removed from the drill sites and stored in a Mundubbera storage
shed. The 12.5% fraction was further split with a 50:50 splitter to produce a sample
for dispatch to and analyses by ALS
The samples were dispatched in self-seal plastic bags to reduce the loss of the fine
clay fractions.
In addition to ALS‘s QA/QC services, the company submitted a random duplicate
sample from each of the dominant lithologies (i.e., bauxitic clay, grey plastic clay,
kaolinite clay, and sandy clay) from each hole along with a standard sample. (OREAS
– 999)
Remnants of the 12.5% split, stored on the Gold Coast, and the retention samples
(the 87.5% split) stored in Mundubbera are available for further evaluation and testing.
The 4C drill core was logged at 1:100 scale as was the air core samples. Core
recoveries were measured and lithological contacts recorded on the split tube before
being placed in plastic core trays holding 2 x 1metre core sections. Placing the core
in the core trays commonly resulted in breaking of the core runs.

Quality of assay
data and
laboratory tests
The clay samples for analysis were weighed, dried and milled to a nominal -75um
before an XRF assay in the Brisbane lab of ALS using the XRF-ME method. A Loss –On
–Ignition (LOI) to ascertain the amount of hydroxyl water in the clay minerals was also
completed.
Kalotech has supplied a standard (OREAS 999) sample with each hole along with a
duplicate of each rock type from each hole. The reproducibility of the alumina and
trace element values has been excellent. Several standards for the XRF and LOI
analyses were also included by ALS. The reproducibility of these standards has been
satisfactory.
An evaluation of the repeatability is good. The duplicate samples showed low scatter
and good linear correlation with the original assay values. Overall, there was a high
level of precision and good accuracy with no evidence of bias in the sampling method
of the assays based on the QC analysis.
The 4C core was weighed by ALS laboratories on receival, i.e. wet, then dried and
weighed again i.e. dried weight. The samples were then crushed, and a 1-kilogram
fraction was milled with a 200gm split sample for assay were retained in paper
sachets. The same XRF method as used for the air core samples was used for the 4C
drill samples
Verification of
sampling and
assaying
RC twining of air-core holes has been completed at 9 sites, testing the desired spacing
for converting the Indicated Resource to a Measured Resource and producing larger
bulk samples of clay for further evaluation and for marketing purposes.
Data Storage The .xlsx data from ALS are stored along with the .csv and .pdf files on computer and
external hard disk. A further copy is stored on a Company Director’s computer. These
data have been entered into the Excel database as separate files and added to the drill
log as a composite file.
Location of data
points
The holes were filled and capped with a 1m long PVC tube. The hole number was
recorded on the PVC cap with a black paint marker. The hole drill collars were
surveyed with a Garmin GPS map 60CSx GPS using Datum: MGA94 Zone:56J.
The averaging mode was used until an accuracy of <2m was obtained. This process
generally took 20-30 minutes to achieve the <2m accuracy.
A drone photo-grammatic survey was subsequently completed by consultants,
Ausrocks.
Data spacing
and distribution
The drill pattern was completed at on a 100m spaced holes on lines 100 metres apart.
The holes were drilled on surveyed MGA94 North trending Long Sections and the holes
were spaced to achieve 100m spaced holes on the GDA 94 East trending Cross
Sections. On 2 sections 315800E and 315850E holes at a 50m spacing was
completed.

Commentary Competent Professional – Graham Rolfe
Within the resource modelling software, Micromine, the different lithologies, i.e.,
bauxitic clay, grey plastic clay, white kaolinite clay, and sandy clay, were modelled on
both the long and cross sections to produce 3D solids. All TDAC and TDRC drill holes
were logged and sampled at 1m length intervals, and no further compositing was
performed.
The Competent Person’s opinion is that in the drilled area, the geological and grade
continuity at the data spacing is adequate for classification of mineral resource as
Measured and Indicated Class, with the class dependent on the data spacing. At the
northern end of the drilled area, a small area has an Inferred Resource due to the
paucity of drill holes.
Orientation of
data in relation
to geological
structure
The geological nature of the clay zones is generally near flat lying with gentle folding
into domal structure with a long section length of 1 kilometre and a width of +400m.
This drill program is not considered to be biased.
This drill orientation is vertical across a shallow dipping stratigraphy, so the drill
orientation is at a high angle to the sediments.
Orientation of
data in relation
to geological
structure
All drill-holes were drilled vertically intersecting the full zone width of the near flat lying
stratigraphy. Therefor there is low risk of bias due to an unfavourable drill orientation.
Sample security The Retention Samples were removed from the drill site and securely stored in a
Mundubbera storage shed. The 12.5% samples for XRF analysis were transported
from site to the ALS Laboratory in Brisbane after the insertion of the duplicate and
standard samples. The 200g duplicate assay pulps are stored in the Company’s Gold
Coast Storage Shed.
The 4C drill core has also been stored in the Mundubbera storage shed.

Exploration
done by other
parties
14 RC drill holes were completed by Australian Bauxite in an earlier evaluation for
bauxite. The data from these holes is not used in the Clay Resource estimation.
Kalotech drilled 2 phases of air-core drilling in February and November 2021,
investigating the kaolin occurrence. The Drilling Contract was assigned to Associated
Exploration DrillingPtyLtd.
Geology The kaolin mineralisation, being investigated as having economic potential, occurs
within white claystone and clayey sandstone, under a surficial hematite rich bauxitic
clay and an underlying grey plastic clay.
The bauxite clay- grey plastic clay- white kaolinite clay and sandy clay sequence has
been mapped by the GSQ as a Tertiary sedimentary sequence on the Jurassic
Evergreen Formation. The flat lying bauxitic horizon has been formed as a regolith on
a gently folded plastic clay-kaolinite clay-sandy clay sequence of the Jurassic
Evergreen Formation.

Section 3 Estimation and Reporting of Mineral Resources

(Criteria listed in section 1, and where relevant in section 2, also apply to this section.)

Criteria Description Competent Professional – Chris Ainslie/Graham Rolfe
Database
integrity
The database was originally constructed, validated and electronically provided by
Graham Rolfe (Rock-Ex-Enterprises Pty Ltd) to Ausrocks Pty Ltd. Ausrocks
reformatted the database into appropriate file formats checking the veracity of the
assay results. The data was further validated and cross-checked against the
geological logs. Micromine software 2022 validated the files which were used for the
Mineral Resource Estimate. To ensure continuity and validity across the data sets,
three separate files which cross-referenced the data were used. These were as
follows:

Collar File – This file contains the Hole ID, Location (Northing, Easting and Z
value), Azimuth and Inclination of each hole.

Interval File – A file containing the information collected at intervals (depth
from, depth to) downhole. This included colour, hue and sample assay
values.

Survey File – Showing the azimuth, orientation, or each hole. Note all holes
were drilled vertically, which simplified the data.
Sample intervals were collected at 1m throughout the drilling program. No sample
bias based on the sample interval length.
Site visits The Competent Person (Graham Rolfe) undertook a site visit and was present for all
drilling campaigns.
The original resources estimation Competent Person (Chris Ainslie) undertook a site
visit on 10 December 2021.
Geological
Interpretation
5 lithologies have been determined by geochemistry and geological interpretation –
Bauxitic Clay, Plastic Clay, Kaolinite Clay (High Iron), Kaolinite Clay (Low Iron) and
Sandy Clay.
The interpreted geology of the Toondoon Kaolin Project is relatively robust, and any
alternative interpretation of the deposit is considered unlikely to have a significant
influence on the Mineral Resource Estimate undertaken. The known nature and
formation of the deposit, together with consistent high grades achieved in drillholes,
places a high degree of confidence in the geological interpretation. The detailed level
of drilling has enabled confidence of the interpreted geology. Continuity of geology
and grade (assays) can be readily identified and traced between drillholes.
Dimensions The Resource is approximately 2,000 long (NE-SW) and averages 500m wide (NW-
SE) covering a surface area of approx. 82.5 hectares.
The approximate average depth for each domain is as follows:

Bauxitic Clay: 4.0m

Plastic Clay: 5.7m

Kaolinite Clay (High Iron): 2.0m

Kaolinite Clay (Low Iron): 4.3m

Sandy Clay: 13.3m (open at depth)
Estimation and
modelling
techniques
Micromine Software 2022 was used to complete the Upgraded Mineral Resource
Estimate in accordance with the JORC 2012 Code. A block model was generated to
model the overall deposit shape and volume. The block model was defined by the top
of the resource (topography), the base of the resource (base of the drillholes), and the
interpreted geological boundaries. Parent blocks were sized at 10mE x 10mN x 1mRL.
Sub-blocks were sized at 1mE x 1mN x 1mRL. The block model was optimised, and
the average Al2O3grade and quantity of the resource at varied reporting levels were
computed.
The block model was subjected to statistical and geostatistical analysis and the
Ordinary Kriging (OK) method was used to populate the blocks. The Inverse Distance
Weighting (IDW) method was used to check the model and yielded similar results.
Swath plots were used to validate the interpolation technique to ensure accuracy. All
assayed elements were modelled in the block model.
The following parameters and assumptions formed the basis for the MRE Maiden in
accordance with the JORC Code (2012).

5 lithologies determined by geochemistry and geological interpretation –
Bauxitic Clay, Plastic Clay, Kaolinite Clay (High Iron), Kaolinite Clay (Low Iron)
and Sandy Clay.

Topography – DEM sourced by drone survey.

The resource boundary was determined by a combination of Mining Lease
Boundary, geological interpretation and area of influence considerations.

Density values as provided by Project Geologist.

All assayed elements were reported as secondary elements constrained to
the cut-off grade of Al2O3.
Moisture Mineral resource tonnages are estimated and reported as dry metric tonnes.
Cut-off
parameters
A cut-off grade of 32% Al2O3was applied to the white kaolin clay data for the modelling
and estimation process. The cut-off grade aided with determination of the domain
boundaries which were determined by analysis of raw assay data down each
individual drill hole. The cut-off grade applied is consistent with industry practice for
these types of Kaolin deposits.
Mining factors
or assumptions
No specifics have been factored into this MRE. Mining by open cut method is
assumed and the block model vertical dimension of 1m reflects this assumption for
small-medium equipment.
Metallurgical
factors or
assumptions
No metallurgical factors or assumptions have been included or deemed required at
this stage of the resource estimation.
Environmental
factors or
assumptions
No environmental factors or assumptions have been included at this stage of the
resource estimation.
Bulk density 2021 Phase 2: Ten samples from bull-dozed trenching were submitted to ALS for
specific gravity analyses using the OA-GRA 08a method. The method records the
specificgravityrelative to unitywith submersion of a wax coated sample into water.

The average SG for the rock types bauxitic clay, kaolinite clay and sandy clay were determined and the average for the respective rock types was calculated. No plastic clay was recovered so no analysis was conducted for this rock type.

The sandy clay consists of kaolinite clay and fine to medium grained quartz. It could be anticipated that the SG of the sandy clay would be higher than the kaolinite. However, it is generally lower indicating there must be more pore space, resulting in a lower SG.

The grey plastic clay generally consists of kaolinite with iron oxides and anatase. As the amount of quartz, iron oxide and anatase in the kaolinite does not have a consistent effect on the SG measurements, these elements will have little effect on the SG of the grey plastic clay. It was assumed that the SG of the plastic clay would be similar to the kaolinite clay i.e., 1.74 t/m[3] .

The assumed density values first used in the MRE were Bauxitic Clay - 2.05 t/m[3] ; Grey Plastic Clay - 1.74 t/m[3] ; Kaolinite Clay: 1.74 t/m[3] and Sandy Clay: 1.69 t/m[3]

2025 Phase 3: With the 4C core drilling, further DBD measurements were completed on the drill core. The initial batch, 158051, of white clay and the immediate overlying grey plastic clay samples were split, sampled, and dispatched to ALS Laboratories, Brisbane. Core splitting was affected by using a metal spatula because the core was sufficiently soft. The broken nature of the core after splitting made it very difficult to estimate the 50% sampling of the core. The effective fraction of sampled core was calculated using the retained core weight and the dispatched weight received by ALS Laboratories.

For the initial batch, 158051 ALS weighed the dispatched samples as received by the laboratory. The samples were then dried, crushed, and split resulting in about 1kg of material which was pulverized. After ALS had finished assaying batch 158051, The dried reject crushed fraction, the bulk milled fraction and the smaller assay packet were collected and returned to the Mundubbera shed. Two weighing machines were used, a larger platform machine suitable for weighing tared core trays and a smaller one suitable for weighing smaller pieces of core and the smaller bags of samples. For the assayed samples of Batch 158051 the dried weight of the crushed fraction and the two pulverized sample bags were weighed and summed to give the dried weight of each sample. The dispatched sample split was the weighed as a wet sample received by ALS. The remaining core of the whole core and the split and sampled sections were weighed. This resulted in the retained core weights of the samples of the initial batch. The weight of the retained core of the split and sampled sections were added to the dispatched weights of the samples received by ALS, to calculate the weight of the whole wet core of these samples. As the core was not exactly a 50% split, the percentage of the dispatched sample was calculated as a fraction of the total wet core weight, i.e. retained wet core weight plus the dispatched sample weight. The percentage of free water in the samples was calculated by subtracting the dried sample weight from the dispatched wet weight of the sample, expressed as a percentage. The density of the dried sample was calculated by dividing the total dried sample weight by the calculated volume of the dried split. The volume of the dried sample was calculated by using the core surface area multiplied by the sample length, i.e. 22/7.r[2] .l, and reduced by the dispatched fraction of the total volume. The second batch 158052 was treated differently. The whole core was initially weighed, i.e. wet core weight. The core was split and sampled after the individual samples were processed. As with the first batch, the dispatched wet samples were weighed by ALS, prior to drying. After drying before crushing, splitting, and pulverizing

==> picture [150 x 43] intentionally omitted <==

the sample was weighed again, i.e. dried weight. Like Batch 158051, the density of the
dried samples and the free water contents were calculated.
The drill recovery factor resulted in slightly higher dried densities, due to the slightly
higher weights of recovered core with the same volume.
The density of the bauxite clay, the grey plastic clay, the high iron white kaolin clay,
the low iron (<0.5%) white kaolin clay and the sandy clay were calculated using the
weight of dried core, corrected by recovery factors and the volumes of the sample
interval.
The resultant DBD of the lithologies are:
Bauxitic clay - 1.66 t/m3
Gray plastic clay - 1.46 t/m3
High iron (>0.5%) white kaolin clay - 1.42 t/m3
Low iron (<0.5%) white kaolin clay - 1.44 t/m3and
Sandy Clay - 1.65 t/m3
Classification The Toondoon Kaolin Project has been broadly defined by drilling, and the geological
controls are reasonably well understood. The drill spacing and interpreted
geological continuity allowed three resource categories to be defined (Measured,
Indicated, and Inferred Mineral Resource) in accordance with the JORC 2012 Code
In accordance with the JORC Code (2012), requirements were developed to allow for
areas of the Toondoon Kaolin Project to be classified as a Measured, Indicated, and
Inferred Mineral Resource.

To meet the requirements of a Measured Mineral Resource, drillholes had to
show geological continuity between gridded drillholes with a confirmatory
spacing (100m x 100m with infill holes with a minimum of one hole drilled in
between each 4 x 100m drillhole ‘square’).

To meet the requirements of an Indicated Mineral Resource, drillholes had to
show geological continuity between gridded drillholes with a reconnaissance
spacing (100m x 100m)

To meet the requirements of an Inferred Mineral Resource, drillholes showed
geological continuity between gridded drillholes with a reconnaissance
spacing (100m x 100m) but had limited cross-sectional control (2 or 3
drillholes in cross section).
The result appropriately reflects the Competent Persons view of the deposit.
Audits or
reviews
All calculations have been reviewed internally by Ausrocks.
Discussion of
relative
accuracy/
confidence
It is the opinion of the Competent Persons that the relative accuracy and confidence
level across the reported geological intervals is adequate, given the drill density and
the continuity of geochemical samples.

APPENDIX 4

Kaolinite Content of Toondoon Ore Clays

The rationale for updating the kaolinite content in Toondoon ore clays from 80-90% to >90%, in accordance with JORC (2012) guidelines, is based on a more accurate understanding of thermal analysis data presented in the CQU Final report[14] , coupled with additional methods of indirectly determining kaolinite content based on mineralogical and chemical data[15] .

A comprehensive rationale for this update is presented in Table 21 .

Table 21: Kaolinite Content of Toondoon Ore Clays

Aspect Previous Estimate
(>80%)
Updated Estimate
(>90%)
Rationale for Update
Testing Methods TGA (350–650°C),
limited XRD
TGA (350–750°C), XRF
Al₂O₃ reconciliation,
qXRD, LOI
Multiple complementary methods
now used, aligning with best practice
under JORC (2012) for mineralogical
confidence.
Analytical Basis Based on conservative
interpretation of TGA
data20(350–650°C)
from CQU report
Incorporates broader
TGA range (350–

reconciliation, qXRD,
and LOI
The previous method
underestimated kaolinite due to a
narrow temperature range. Updated
methods capture full dehydroxylation
range, improving accuracy.

Plastic clay = 91.2%

High-iron kaolinite = 91.9%

Low-iron kaolinite = 92.8%.
XRF Al₂O₃
Reconciliation
Not emphasised Used to calculate
kaolinite content,
assuming minimal Al-
bearing impurities
For example, 35.5% Al₂O₃ / 39.5%
(theoretical max) = ~90% kaolinite.
Valid if muscovite and other Al
phases are minor (confirmed by
XRD).
qXRD and XRD
Support
Limited or qualitative Quantitative XRD
confirms kaolinite
dominance in PC, HI,
and LI domains
qXRD shows minimal impurities and
confirms kandite phase dominance,
supporting high kaolinite purity.
∑kandite and amorphous material =
>90% for all 3 domains.
LOI and Elemental
Closure
Not fully integrated Al₂O₃ + SiO₂ + LOI =
>90%
High elemental closure supports
minimal non-kaolinite phases,
reinforcing high kaolinite content.

Plastic clay = 91.7%

High-iron kaolinite = 95.2%

Low-iron kaolinite = 97.4%
Consistency with
Mineral Resource
Update
Based on older data Aligned with 2025
Mineral Resource
update and DBD data
Ensures internal consistency across
technical documentation and
supports classification confidence.
JORC (2012)
Compliance
Conservative, possibly
under-representative
More representative of
actual mineralogy
JORC requires reasonable prospects
for eventual economic extraction.
Higher kaolinite content supports
this byindicatinghigher-grade feed.

Summary

The decision to update the kaolinite content from >80% to >90% is supported by a more comprehensive and technically robust dataset.

The previous estimate, while not incorrect, was based on a narrower interpretation of thermal analysis data and did not fully leverage the available mineralogical and chemical data.

The updated estimate integrates:

  • Thermogravimetric Analysis (TGA) over a broader temperature range (350–750°C),

  • XRF-based Al₂O₃ reconciliation assuming minimal interfering phases,

  • Quantitative XRD (qXRD) confirming kaolinite dominance,

  • Loss on Ignition (LOI) and elemental closure supporting mineralogical purity.

These methods collectively provide a more accurate and defensible basis for the >90% kaolinite claim, aligning with JORC (2012) principles of transparency, materiality, and competence.
