About Altona Rare Earths Plc

The Company is currently developing Monte Muambe, its flagship Magnet Rare Earths Project, located in Northwest Mozambique. The Project was acquired in June 2021, and the Company has so far drilled over 7,800m, and defined a maiden JORC Mineral Resource Estimate of 13.6 million tons at 2.42% TREO. A Competent Person Report including the Scoping Study for Monte Muambe was published on 18 October 2023. The Project is now at Prefeasibility Study stage, with a focus on metallurgical testing and process.

Altona is presently diversifying its portfolio by acquiring a limited number of critical raw material projects to complement Monte Muambe. The acquisition of the Kabompo South copper project in Zambia and of the Sesana copper-silver project in Botswana represent the first steps towards the implementation of this expanded strategy.

CHAIRMAN'S STATEMENT

Our Company's results for the year ended 30 June 2024 cover a period of further change, development and progress for our Company, consistent with our strategy.

Having listed on the Official List in June 2023, we believe this step has improved our standing in the eyes of potential partners and counterparties. It has enabled us to access the capital markets more effectively.

We have undertaken fundraises to support the plan for Monte Muambe, and we have welcomed new shareholders on to our register. Progress has occurred at Monte Muambe, with our interest having increased to 51% and our formal application having been made for a 25 year mining concession for that project. The scoping study results were encouraging and positive.

2023/2024 saw output for rare earths rise globally, demand for rare earth elements softened due to the global economic downturn, and competition in production has brought further pressure on producers. The equity markets have been difficult for junior miners, especially for those of us still in the exploration phase. Nonetheless, we take a long term view, and believe our strategy to create and to nurture a diversified portfolio of mineral assets in Africa to be the right one.

During the period under review, we acquired a copper project in the Mufumbe district in Zambia, and entered into an option to acquire a copper and silver exploration licence in Botswana - the Sesana project. These acquisitions are consistent with our strategy, and we continue to look for appropriate acquisition opportunities.

We face the future with determination to deliver on our strategy, with a focus on its implementation, and with resolve to generate value for our shareholders. Your board is cohesive, aligned, and single minded about delivering results. Our work continues.

CEO'S STATEMENT

The Financial Year 2024 was a year of significant value building for Altona.

The Company's focused exploration approach at the Monte Muambe rare earths and fluorspar project led to the production of a maiden JORC mineral resource estimate ("MRE") and of a positive scoping study barely 2 years after the acquisition of the project. With 13.6 million tons at 2.42% TREO, out of which almost 60% is already in the Indicated category, this MRE forms a solid base for further increase and for a future ore reserve statement. As a result of the completion of this milestone, Altona's ownership of this important rare earths resource increased from 20% to 51%. The project is now at prefeasibility study level.

According to Adamas Intelligence[1], the global consumption of NdBeB magnets rose by 13.3% in 2023. This largely reflects the increasing permanent magnets demand for electric vehicles drive trains, and wind turbines, driven by the green energy transition. The same analyst forecasts the demand to grow at a compound annual growth rate ("CAGR") of 8.7% from 2024 through 2040, whereas the supply is expected to grow at a CAGR of 5.1% over the same period. This underpins strong long-term market fundamentals, pushed by both decarbonisation and robotics applications, the latter being expected to become the largest global demand driver for permanent magnets by 2040.

Rare earths prices, however, after a peak in 2021 and 2022, have failed to meet analysts' previsions and fell to their current level (about USD 75 per kg for Neodymium-Praseodymium alloy). Such prices have delayed or hindered the development and funding of many rare earths projects.

Cognisant of these facts, in early 2024, the Company announced and started to implement an expansion and diversification strategy in order to mitigate its exposure to rare earths only, and to build a portfolio of critical raw materials projects which we hope will open opportunities for early monetisation of these assets. The Board defined clear selection criteria covering a limited number of commodities in tier 1 African jurisdictions and narrowing down on low acquisition cost and low initial exploration cost opportunities.

The acquisition of the Kabompo South copper project in Zambia in March 2024 and the option to acquire the Sesana copper-silver project in Botswana in April 2024, (this option being exercised post year end in July 2024) marked the start of this strategy's implementation.

The Sesana project, located in the heart of the emerging Kalahari Copper Belt ("KCB"), and in a jurisdiction widely regarded as the most mining-friendly in Africa, is particularly exciting. The Sesana licence covers a well identified geological feature, the D'Kar - Ngwako Pan formations contact, which is known to host copper mineralisation in the KCB. It is located just about 25km from MMG's Khoemacau Zone 5 underground copper-silver mine, where production capacity is currently being increased.

As part of the implementation of this strategy, Altona has also initiated a review of the fluorspar production potential of Monte Muambe. This includes the possibility of rapidly putting the low-tonnage / high-grade (50% to 70% CaF2) fluorspar veins located in the Western part of the intrusion into production, thus generating much needed cash flow for the Company. I am particularly excited by this opportunity to turn an existing asset into a profit centre in the short term.

Fluorspar is a little-known but very important critical raw material. Fluorspar demand and prices have been steadily increasing over recent years and are expected to increase further as green energy transition applications such as the manufacturing of electric vehicles batteries require significant amounts of fluorspar. High-grade fluorspar veins lend themselves to the production of metallurgical grade fluorspar through simple extraction, comminution and gravity concentration methods.

In the meantime, the Company will continue derisking the Monte Muambe rare earths project in order to unlock the tremendous value it created through 3 years of investment in this project. This will be done through focused spending on priority activities such as securing a 25 year mining concession (which is expected to be granted before the end of this year) and on-going metallurgical testing, as well as continuing to seek a strategic investor involved in the rare earths supply chain.

OPERATIONS REVIEW

Financial Year 2024 activities - Monte Muambe Rare Earths and Fluorspar project

Maiden JORC Mineral Resource Estimate

On 25 September 2023, Altona published Monte Muambe's maiden JORC Mineral Resource Estimate, reported in the table below using a 1.5% TREO cut-off.

Notes:

• Million tonnes are rounded to one decimal place. Grades are rounded to two decimal places for % and whole numbers for ppm.
• The MRE has been reported in consideration of reasonable prospects for eventual economic extraction (RPEEE) using a pit shell based on a 1.5% TREO cut-off, revenue of 24.65 USD/kg TREO MREC and average total recovery to MREC of 48%.
• Mineral resources are reported as dry tonnes on an in-situ basis.
• Rare earth elements are inclusive of the TREO and not additional to it.
• "NdPr Oxide" is the sum of Nd2O3 and Pr6O11.

The MRE's tonnage and grade compares favourably to Ore Reserve Statements of more advanced carbonatite REE-projects in Monte Muambe's peer group in Africa and in Australia.

The MRE covers two (Target 1 and Target 4) of 11 identified REE targets at Monte Muambe and there is considerable scope to increase its size. As part of the Prefeasibility Study, the Company intends to increase the tonnage and the level of confidence of the existing MRE through:

• In-fill drilling at Target 1 and Target 4 (to take the MRE on these two mineralised bodies to Measured and Indicated levels);
• Down-dip drilling at Target 1 and Target 4 (to increase the tonnage);
• A re-evaluation of the potential viability of Target 6, which has known high-grade mineralisation at a depth of 30 to 50m below the surface;
• Resource drilling at Targets 3, 9 and 11 among others.

Scoping Study

On 18 October 2023, Altona published an updated CPR including a Scoping Study (the "Study") for the Monte Muambe project.

The Study was prepared by geology and mining consultancy firm Snowden-Optiro, to assess the potential viability of an open pit mining and MREC production operation, to assess project development options, and to give sufficient confidence to the Company to advance to the Prefeasibility Study stage.

The Study is preliminary in nature and includes material assumptions outlined in the CPR, including product price assumptions. Capex estimates qualify as Class 4 estimates as per the Association for the Advancement of Cost Engineering (AACE) Recommended Practice 47R-11. The accuracy of the opex and of the initial capex estimate is assessed at +35 % to −30 %. The base case includes an indicative life of mine extraction and production schedule, which is based on a Mineral Resource Estimate, 58% of which classified as Indicated and 42% as Inferred.

The Study takes into consideration open-pit mining of Target 1 and Target 4, at a Life of Mine ("LOM") strip ratio of 1.6, over a period of 18 years. An anticipated 750,000 tonnes of ore per annum will be extracted and processed through a beneficiation plant to produce a rare earths concentrate. The beneficiation process will include crushing, milling and flotation. The concentrate will then be processed through a hydrometallurgical plant to produce an average of about 15,000 tonnes of MREC per annum. The hydrometallurgical process will involve a weak acid gangue leach, followed by rare earths leaching and purification. The MREC product will be packaged and transported via existing road infrastructure to the port of Beira, in Mozambique, for export.

Schematic layout of the Monte Muambe project

Base Case Technical and Economic parameters are summarised in the table below:

Using an NPV of US$283.3 million with an applied real discount rate of 8%, the Project is most sensitive to revenue (price, recovery, grade and exchange rates), less sensitive to opex and least sensitive to capex.

Project sensitivity analysis

The Scoping Study demonstrates the potential for Monte Muambe to become a viable mining operation.

Considerable upside potential has been identified in the Scoping Study and will be developed further in the Prefeasibility Study ("PFS"). This includes:

• Increase of the resource base, as well as of the LoM and/or ore extraction rate;
• Mining parameters optimisation;
• Processing and Metallurgy, both for the beneficiation and hydrometallurgical plants;
• Energy sources mix and logistics options;
• Evaluation of the possibility of doing further onsite, in-country or regional separation and refining;
• Setting up Responsible Sourcing systems.

Completion of Phase 2 and holding increase to 51%

On 24 October, in accordance with the Farm-Out Agreement, the Company notified the original shareholders of Monte Muambe Mining Lda of the successful completion of Phase 2 and of its intention to proceed to Phase 3. This triggered the transfer of an additional 31% of Monte Muambe Mining Lda, which was completed on 5 December 2023 and received the formal approval from the Minister on 14 December 2023.

On 14 December 2023, Monte Muambe Mining Lda applied for a Mining Concession over the area of Prospecting Licence 7573L for a duration of 25 years. At the date of this report, the application is in the final stages of its process and the Mining Concession is expected to be granted shortly.

Phase 3 - Prefeasibility Study

During the 3rd quarter of 2023, the Company carried out additional drilling (10 RC holes totalling 790m) and trenching at Monte Muambe, with a view to define better the mineralised envelope at Target 4, and to test Target 3.

Significant intercepts, based on on-site p-XRF assays, include:

• Sum of La, Ce, Nd, Pr and Y from Altona's pXRF assays, in oxide percent.

Other Prefeasibility Study activities carried out during the financial year include the thorough mineralogical characterisation of a representative 100kg ore sample from Target 1, which was sent to SGS Lakefields in Canada.

Financial Year 2024 activities - Other projects

In February 2024, the Company carried out a review of its strategy and announced its intention to expand and diversify its portfolio of projects in Africa into other critical raw materials. The Company started assessing potential new opportunities with a focus on projects having a low entry-cost and a clear pathway to early results and to majority ownership. During the financial year, the Company advanced on the acquisition of two projects: the Kabompo South copper project in Zambia and the Sesana copper-silver project in Botswana.

Kabompo South Copper project, Zambia

On 28 March 2024, the Company announced entering into an agreement with Sustineri Group Ltd and with the beneficial owners of Phelps Dodge Mining (Zambia) Limited to acquire the entire issued share capital of Phelps Dodge Mining (Zambia) Limited, the registered holder of Large Scale Exploration Licence 21403-HQ-LEL ("the Kabompo South Licence"), located in the Mufumbe District of Northwestern Province of Zambia.

The Kabompo South Licence has a surface area of approximately 616 km2 and is valid for copper, cobalt, nickel, lead, zinc, gold and diamonds. The Licence is located 4 km west of the Kamweji copper mine, and 60 km southwest of the Mufumbwe copper mine (22 million tonnes at 1.6% Cu), along strike.

The Kabompo South Licence was previously held by copper giant Freeport McMoRan until this company's strategic decision to exit Zambia in April 2020. The Kabompo South Licence has seen prior grassroot exploration including 4,000 line kilometre of ground magnetometer survey and a partial leach soil geochemistry survey over a 4 kilometre square grid. This work highlighted the presence of a large copper gold silver anomaly in the Northeastern part of the licence area, overlapping a possible demagnetised zone.

Sesana Copper-Silver project, Botswana

On 9 April 2024, the Company announced that it entered into a binding option agreement ("BOA") with Ignate African Mining P/L, with respect to exploration for copper and silver on Prospecting Licence PL2329/2023 (the "Sesana Licence"), located in the Northwest District of Botswana. This option was exercised post year end and at the date of this document the parties are in the process of finalising the final agreement.

The Sesana Licence is located in the heart of the highly prospective Kalahari Copper Belt ("KCB"), close to major copper-silver discoveries. The Project is located 25 km from the producing Khoemacau underground copper-silver mine and situated in an active exploration area of the KCB (Khoemacau, Galileo Resources, ARC Minerals). Recent airborne geophysical data interpretation shows prospective geological structures for copper-silver mineralisation passing through the Tenement. Botswana is considered one of the most attractive mining investment jurisdictions in Africa, and indeed, in the world.

The Sesana Licence has a surface area of about 274 km2 and is valid until 31 March 2026, after which it can be renewed twice for periods of up to 2 years each. It is valid for copper, cobalt, gold, silver, lead, zinc, aluminium, chromium, iron, titanium and platinum group metals.

Renowned Kalahari Copper Belt expert David Catterall was subsequently hired to guide and advise the Company with respect to its exploration program for the Sesana Licence.

Post-Financial Year activities

Monte Muambe Rare Earths and Fluorspar

The Company's post-financial year activities are focused on continuing to derisk the project, through the grant of the Mining Concession, and through key metallurgical testing activities.

As at the date of this report, the process of the Mining Concession application is believed to be in its final stage.

The representative ore sample sent to SGS Lakefields is currently undergoing metallurgical testing, with a focus on flotation rougher tests. Initial test results, received in September 2024, are highly encouraging and show a rare earth recovery of 69.3%, and a good selectivity between rare earths and fluorspar.

On-going flotation metallurgical testing is expected to improve the characteristics of the rare earths concentrate which will be produced on site and subsequently processed through a hydrometallurgy plant, also on site, to produce Mixed Rare Earths Carbonate.

This is expected to lead to a significant reduction of the hydrometallurgy plant opex and capex, and to an improvement of the financial results outlined in the scoping study.

In October 2024, the Company started a re-assessment of the potential of Monte Muambe for fluorspar production. Disseminated fluorspar in rare earth ore from Target 1 and Target 4 is considered as a potential by-product of future rare earths mining and is covered in the scope of current metallurgical testing. In addition, low-tonnage high-grade hydrothermal fluorspar veins located in the western part of the carbonatite intrusion may lend themselves to short-term development into a producing mine.

Kabompo South Copper

A field visit was undertaken by the Company's CEO and lead geologist Cedric Simonet in September 2024. Subsequently, geophysical consultant Earthmaps Consulting was hired to carry out the reprocessing and interpretation of legacy geophysical data to generate soil geochemistry follow up for copper and possibly for diamonds.

Sesana Copper and Silver

On 29 July 2024 the Company announced that it notified Ignate African Mining P/L of the exercise of the option over the Sesana Project. At the date of this document the parties are in the process of finalising the final agreement.

Outlook

2024 has been an important year for Altona, which saw the completion of key milestones for the Monte Muambe Rare Earths and Fluorspar project, including a maiden JORC MRE, a scoping study, an application for a 25 year Mining Concession, and the increase of the Company's ownership of the project from 20% to 51%.

The Company also made a strategic decision to expand and diversify its portfolio of critical raw materials projects in Africa, targeting opportunities which:

• Are located in tier 1 African mining jurisdictions
• Have a low acquisition cost and a clear path to majority ownership
• Have a low initial exploration cost and can be fast-tracked
• Will contribute to building a portfolio of assets widening monetization and early revenue options

The acquisition of the Kabompo South copper project in Zambia and the Sesana copper-silver project in Botswana were two important steps towards the implementation of this strategy.

Over the past year, green energy transition driven demand for rare earths has tremendously increased. The supply chain remains largely dominated by China, but alternative supply chains are steadily developing in Europe, America, Australia and Asia. Neodymium and praseodymium prices, however, remain depressed, well below the peak levels of late 2021 and early 2022. In this situation, the Company is convinced that its diversification strategy is sound and appropriate.

Over the next year, Altona will continue to build a balanced portfolio of assets in accordance with the above strategy, through carefully selected acquisitions and targeted exploration. This is expected to open up early monetisation opportunities, through disposal or through short-term development of suitable assets.

The Company will continue to derisk Monte Muambe through investment in priority activities including the completion of the Mining Concession process, an application for land rights, the on-going metallurgical studies, as well as securing a strategic investor involved in the rare earths mid-stream or down-stream value chain for the project.

The Company has also started to review the potential for fluorspar production at Monte Muambe. Fluorspar is an important critical raw material which is used in many industrial manufacturing processes, including for the production of electric vehicles batteries. Because fluorspar has been used in many other application, its price is not subject to the sharp variations that rare earths have experienced over the past years. Fluorspar is often associated to rare earths in carbonatites. At Monte Muambe fluorspar occurs both in disseminated form in the rare earths ore (on-going metallurgical testing is also aimed at recovering fluorspar as a by-product of rare earths), but also in low-tonnage high-grade fluorspar veins.

The high-grade fluorspar veins will be the object of a conceptual study to assess the possible short-term development of a fluorspar mining operation at Monte Muambe, thus opening up the possibility for early cash flow from this asset.

The Company will also commence exploration activities at Kabompo South and Sesana, with the aim of rapidly building the value of these two assets.

CORPORATE REVIEW

Financial Review

Statement of Financial Position

During the financial year to 30 June 2024, the Company experienced growth in key areas, reflecting strategic investments and capital expenditures. Investments increased from £1.6 million to £2.1 million, driven by an increase in ownership in the underlying asset, Monte Muambe Mining Lda, from 20% to 51%, and additional capital contributions to fund the ongoing development of this asset. Intangible assets also grew from £1.3 million to £1.6 million, primarily due to continued expenditure on the mining asset, demonstrating the Company's commitment to developing and enhancing its core operations. Trade receivables and payables remained stable, while loans increased by £0.4 million, reflecting additional financing secured during the year.

Equity saw a slight increase during the year, rising from £25.2 million to £25.4 million. Post year end equity increased by a further £0.8 million to reflect the equity raise of £0.4 million, the conversion of outstanding CLNs of £0.3m and the settlement of creditors through shares in lieu of cash payment of £0.1 million.

Income Statement

The Company's income statement highlights a stable operating performance, with the operating loss remaining steady at £1.1 million for both 2023 and 2024. However, finance costs increased significantly from £0.2 million to £0.5 million, primarily due to the finance costs associated with the increased debt taken on in the year and the warrants issued with respect to this raising of finance. This increase in finance costs underscores the impact of the Company's financing strategies on its overall financial performance. During the year the Company renegotiated the outstanding CLNs which led to the conversion, post year end, of £0.3 million debt into equity, improving the Company's balance sheet and another £0.2 million of CLNs being reprofiled as debt with a repayment date of 30 October 2025.

Liquidity and Cash Flow

The Company's liquidity position saw a reduction in cash reserves, decreasing from £1.1 million to £0.4 million by year end. This reduction was mainly due to the corporate costs of being a public company and the ongoing capital expenditure on the mining asset at MMM. The Company received a further £0.3 million in loans during the year and as mentioned above renegotiated/reprofiled its existing CLNs. It also received subscription funds of £0.3 million for equity that was issued post year end.

Despite this decrease in the cash position, the Company strengthened its liquidity position with a new loan package of £0.9 million from two investors with a fixed interest rate of 12% and repayment date of 30 October 2025. This money is being received in 8 tranches with £0.1 million received before year end.

This investment will allow the Company to enhance its asset base, manage its financial obligations, and position itself for future growth while maintaining stability in its core operations.

Board Changes

There were no Board changes during the financial year. However, post year end the Board saw a significant revision with the resignation of Audrey Mothupi on the 1 August 2024 and Martin Wood, the Chair on 10 August 2024.

The Company appointed Kristoffer Andersson on the 1 August 2024, as a Non-Executive Director and we were pleased that Simon Charles was willing to step up to fill the Chair's position, effective from 10 August 2024.

Post Balance Sheet Events

On 19 July 2024, the Company announced the issue of 76,248,759 new ordinary shares as follows.

• 39,400,000 Shares were issued to raise funds of £394,000
• 33,300,000 Shares were issued for the conversion of existing convertible loan notes of £303,000; and
• 3,548,759 Shares were issued to certain Directors in lieu of fees and to various other creditors.

On 29 July 2024, the Company announced it had exercised its option to acquire a 51% share in the prospecting licence PL2329/2023, in Botswana from Ignate African Mineral (Pty) Ltd for an initial consideration of USD$10,000 in cash and USD$50,000 in shares. The minimum expenditure commitment is USD$100,000 for a 12 month period.

INDEPENDENT AUDITOR'S REPORT TO THE MEMBERS OF ALTONA RARE EARTHS PLC

Opinion

We have audited the financial statements of Altona Rare Earths plc (the 'parent company') and its subsidiaries (the 'group') for the year ended 30 June 2024 which comprise the Statement of Consolidated Profit or Loss and Other Comprehensive Income, the Statement of Consolidated Financial Position and the Parent Company Statement of Financial Position, the Statement of Consolidated Cash Flows and the Parent Company Statement of Cash Flows, the Consolidated Statement of Changes in Equity and the Parent Company Statement of Changes in Equity and notes to the financial statements, including significant accounting policies. The financial reporting framework that has been applied in their preparation is applicable law and UK-adopted international accounting standards and as regards the parent company financial statements, as applied in accordance with the provisions of the Companies Act 2006.

In our opinion:

Basis for opinion

Material uncertainty related to going concern

We draw attention to note 1 in the financial statements, the ability of the Group to meet its projected expenditure is dependent on these further equity injections and / or the raising of cash through bank loans or other debt instruments, and/or government grants, and/or loans. These conditions indicate that a material uncertainty exists that may cast significant doubt over the Group's ability to continue as a going concern and therefore their ability to realise their assets and discharge their liabilities in the normal course of business. Our opinion is not modified in respect of this matter.

In auditing the financial statements, we have concluded that the director's use of the going concern basis of accounting in the preparation of the financial statements is appropriate. Our evaluation of the directors' assessment of the group's and company's ability to continue to adopt the going concern basis of accounting included:

• Reviewing the cashflow forecast and budgets for the going concern period being twelve months from the anticipated date of signing the financial statements and the corresponding key assumptions and inputs used. This included inflows from capital fundraises that management anticipate being achieved in the going concern period;
• Discussing with management regarding the future plans of the group;
• Comparing actual results for the year to forecasts to assess management's forecasting abilities and the accuracy of its forecasts;
• Challenging management's key assumptions and inputs of forecast cash receipts from fundraising and cash outflows in respect of committed costs;
• Testing the arithmetical accuracy of the cashflow forecasts; and,
• Performing a sensitivity analysis on the key assumptions and inputs.

Our application of materiality

The scope of our audit was influenced by our application of materiality. We set certain quantitative thresholds for materiality. These, together with qualitative considerations, helped us to determine the scope of our audit and the nature, timing and extent of our audit procedures on the individual financial statement line items and disclosures and in evaluating the effect of misstatements, both individually and in aggregate on the financial statements as a whole. Based on our professional judgement, we determined the materiality thresholds for the financial statements as follows:

We use performance materiality to reduce to an appropriately low level the probability that the aggregate of uncorrected and undetected misstatements exceeds overall materiality. The audit of Monte Muambe Mining, Lda, the wholly owned subsidiary, was performed by a component auditor, with materiality set by us at £45,000 (2023: £26,000). Performance materiality was set at £31,500 (2023: £18,200). We agreed with the audit committee that we would report to them misstatements identified during our audit above £2,250 (2023: £1,300) for the group audit and £1,875 (2023: £2,755) for the company audit, as well as misstatements below those amounts that, in our view, warranted reporting for qualitative reasons.

Our approach to the audit

The group includes the listed parent company and its subsidiary. We tailored the scope of our audit to ensure that the planned procedures allowed us to gain sufficient appropriate audit evidence to be able to give an opinion on the financial statements as a whole, taking into account the structure of the group and the parent company, the accounting processes, and the industry in which they operate.

As part of our planning, we assessed the risk of material misstatement including those that required significant auditor consideration at the component and group level. In particular, we looked at areas of estimation, for example in respect of the valuation of exploration and evaluation assets, the valuation of investments in subsidiaries and the matters set out in the material uncertainty related to going concern paragraph above. We performed procedures to address the risks identified and for the most significant assessed risks of misstatement, the procedures performed are outlined below in the key audit matters section of this report.

An audit was performed on the financial information of the group's significant operating components which, for the period ended 30 June 2024, were located in the United Kingdom and Mozambique. The component in Mozambique was audited by a component auditor operating under our instruction to undertake a full scope audit. We communicated regularly with the component auditors and we were responsible for the scope and oversight of the audit process. This, in conjunction with additional procedures performed by us, provided sufficient appropriate audit evidence for our opinion on the group and parent company financial statements.

Key audit matters

Other information

We have nothing to report in this regard.

Opinions on other matters prescribed by the Companies Act 2006

In our opinion, based on the work undertaken in the course of the audit:

Matters on which we are required to report by exception

• certain disclosures of directors' remuneration specified by law are not made; or,
• we have not received all the information and explanations we require for our audit.

Responsibilities of directors

As explained more fully in Statement of Directors' Responsibilities, the directors are responsible for the preparation of the group and parent company financial statements and for being satisfied that they give a true and fair view, and for such internal control as the directors determine is necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error.

Auditor's responsibilities for the audit of the financial statements

• We obtained an understanding of the group and parent company and the natural resources sector to identify laws and regulations that could reasonably be expected to have a direct effect on the financial statements. We obtained our understanding in this regard through detailed discussions with management about and potential instances of non-compliance with laws and regulations both in the UK and in Mozambique. We also selected a specific audit team based on experience with auditing entities of a similar size within this industry.

o Listing Rules and Disclosure Guidance and Transparency Rules listing rules

o Quoted Companies Alliance (QCA) Corporate Governance code

o Anti-Bribery and Money Laundering Regulations

o Local industry regulations in Mozambique

o Local tax laws in the UK and Mozambique

• We designed our audit procedures to ensure the audit team considered whether there were any indications of non-compliance by the group and parent company with those laws and regulations. These procedures included, but were not limited to: enquiries of management and discussions with the component auditor, review of board minutes and a review of legal expenses and review of Regulatory News Services (RNS) announcements.
• We also identified the risks of material misstatement of the financial statements due to fraud.
• We considered, in addition to the non-rebuttable presumption of a risk of fraud arising from management override of controls, that the potential for management bias was identified in relation to the valuation of investment in a subsidiary and the valuation of exploration and evaluation assets as described in the Key Audit Matters section above. We addressed this by challenging the assumptions and judgements made by management when auditing these significant accounting estimates and ensuring that there were adequate disclosures included in the respective notes of the financial statements.
• Compliance with laws and regulations at the subsidiary level was ensured through conducting enquiries of management and reviewing correspondence for any instances of non-compliance.

Other matters which we are required to address

We were appointed by the directors of Altona Rare Earths plc on 24 June 2021 to audit the financial statements for the period ending 30 June 2021 and subsequent financial periods. Our total uninterrupted period of engagement is 4 years, covering the periods ending 30 June 2021 to 30 June 2024.

Our audit opinion is consistent with the additional report to the audit committee.

ACCOUNTING POLICIES

GENERAL INFORMATION

Altona Rare Earths Plc (the "Company") is a publicly listed company incorporated and domiciled in England & Wales. Its registered offices are at Eccleston Yards, 25 Eccleston Place, London SW1W 9NF.

On 9 June 2023, the Company announced the admission of the Company's entire issued share capital to the Official List of the Financial Conduct Authority by way of a ‎Standard Listing under Chapter 14 of the Listing Rules and to trading on the London Stock ‎Exchange's Main Market for listed securities ("Admission"). The Company's shares are listed under the new ticker "REE". From 29 July 2024, this two tier system was replaced and the Company is now in the "Equity Shares - Transition" category.

BASIS OF PREPARATION

The consolidated financial statements have been prepared in accordance with UK-adopted international accounting standards and the requirements of the Companies Act 2006. The principal accounting policies are summarised below. They have been applied consistently throughout the year. The financial statements have been prepared on the historical cost basis, except for the assets acquisition which was measured at fair value.

The functional currency for each entity in the Group is determined as the currency of the primary economic environment in which it operates. The functional currency of the parent company is Pounds Sterling (£) as this is the currency that finance is raised in. The functional currency of its main subsidiary is Mozambique Meticals (MTN) as this is the currency that mainly influences labour, material and other costs of providing services. The Group has chosen to present its consolidated financial statements in Pounds Sterling (£), as the Directors believe it is the most relevant presentational currency for users of the consolidated financial statements. All values are rounded to the nearest thousand pounds (£'000) unless otherwise stated. Foreign operations are included in accordance with the policies set out below.

The preparation of financial statements requires the use of certain critical accounting estimates. It also requires management to exercise its judgement in the process of applying the Group's accounting policies. The areas involving a higher degree of judgement or complexity, or areas where assumptions and estimates are significant to the financial information are disclosed in Note 2 to the Report and Accounts.

GOING CONCERN

The Group and Company raise money for exploration and capital projects as and when required. There can be no assurance that the Group and/or Company's projects will be fully developed in accordance with current plans or completed on time or to budget. Future work on the development of these projects, the levels of production and financial returns arising therefrom, may be adversely affected by factors outside the control of the Group or Company.

An operating loss is expected in the 12 months subsequent to the date of these financial statements. As a result the Group and Company will need to raise funding to provide additional working capital within the next 12 months. The ability of the Group and Company to meet its projected expenditure is dependent on these further equity injections and / or the raising of cash through bank loans or other debt instruments/and or government grants and/or loans. These conditions necessarily indicate that a material uncertainty exists that may cast significant doubt over the Group and Company's ability to continue as a going concern and therefore their ability to realise their assets and discharge their liabilities in the normal course of business. Whilst acknowledging this material uncertainty, the Directors remain confident of raising finance and therefore, the Directors consider it appropriate to prepare the consolidated and parent company financial statements on a going concern basis. The consolidated and parent company financial statements do not include the adjustments that would result if the Group and Company were unable to continue as a going concern.
