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 assessing new critical raw material projects acquisition opportunities, including both Rare Earths and non Rare Earths projects.

Operational Review

Activities during the reporting period focused mainly on advancing the Monte Muambe rare earths project, including the completion of a scoping study, the increase of the Company's holding in the project to 51% and lodging a mining licence application. The Company is pleased to confirm that it has successfully completed all the deliverables which were set out in the May 2023 London Stock Exchange IPO Prospectus.

Between July and September 2023, drilling and trenching activities at Monte Muambe allowed the Company to confirm the geometry of the Target 4 mineralised body and resulted in a record drilling intercept of 76m at 3.43% Total Rare Earths Oxide ("TREO") from surface. The presence of high grade rare earth ore at Target 3 was also confirmed, with 30m at 2.74% TREO from surface, underpinning the potential for future resource increases (see below).

In June 2023, the Company engaged the industry-wide respected consultant Snowden Optiro to prepare a maiden JORC Mineral Resource Estimate ("MRE") and a scoping study.

The Monte Muambe MRE published on 25 September 2023 covered Target 1 and Target 4 totalled 13.6 million tonnes at 2.42% TREO, using a cut off grade of 1.5% TREO. 58% of the reported tonnage was in the Indicated category, with the remainder in the Inferred category.

On 18 October 2023, Altona published an updated Competent Person Report ("CPR") including a scoping study ("Study") for an 18 years Life of Mine ("LoM") rare earths mining operation based on the Monte Muambe resource.

The Study considered the extraction and processing of 750,000 tonnes per ore at LoM strip ratio of 1.6. Processing will involve both beneficiation to produce a rare earths concentrate, and further processing of this concentrate through a hydrometallurgical plant, to produce a Mixed Rare Earths Carbonate ("MREC") for export.

With a post tax NPV8 of US$ 283.3 million and a post tax IRR of 25%, the Study demonstrated the potential of Monte Muambe to become a viable mining operation. This has given the Company full confidence to move the project into the Prefeasibility Study ("PFS") stage. The Study also identified considerable upside potential which will be developed further in the PFS, including:

• Increase of the resource base, as well as of the LoM and/or ore extraction rate;
• Mining parameters optimisation;
• Processing parameters improvement, in particular with respect to the concentrate grade (mineralogy and metallurgy studies are currently underway);
• Possible production of fluorspar (fluorite), another Critical Raw Material present at Monte Mumabe, as a by-product of rare earths; and
• Evaluation of the possibility of onsite, in-country or regional rare earths separation and refining ahead of export.

The completion of the Study marked the end of the project's Phase 2 and triggered the increase of Altona's holding in Monte Muambe to 51%, which was announced on 6 December 2023. The Monte Muambe project is now at PFS stage, with a strong focus on the ore metallurgy.

Following the positive results of the Study, the Company lodged an application for a 25 years Mining Concession (the local term for a mining licence), which is currently being processed by the Mozambique Government.

Financial Review

During the reporting period, the Company successfully completed all the planned deliverables as set out in the May 2023 Prospectus.

Non-Current Assets increased from £1.4m to £1.8m representing the increased investment in Monte Muambe and the increase of the Company's holding from 20% to 51% in the project.

The financial loss of the Group for the six months ended 31 December 2023 was £690,000 (H1 2022: £412,000) resulting in the decrease of Net Assets from £1.9m to £1.4m.

In December 2023, cognisant of the unfavourable macroeconomic environment, the Company proactively took several measures to ensure it could continue priority Phase 3 (PFS) value-adding activities beyond the Phase 2 deliverables, while considering the best interest of its shareholders.

These measures included:

• Focusing Monte Muambe PFS activities on metallurgy, the results of which are expected to lead to a significant improvement of the project's opex and capex;
• The on-going assessment of alternative options to fund the entire Monte Muambe PFS;
• Putting in place extended cash preservation measures including reducing corporate costs as well as deferring or paying in equity part of the directors and senior management remuneration (two of the directors continue to be only paid in equity as set out in the Prospectus);

In December 2023, the Company entered into a £250,000 loan facility with Catalyse Capital Limited. £200,000 of the loan was drawn down in Q1 2024. Net cash flow used in operations was £758,000 and net cash outflow from investing activities was £278,000. The Company also was able to reduce its payables by £251,000 in the period (a balance from the delayed listing in May 2023). The cash balance was £73,000 at the period end, and c.£150,000 at the date of this report.

Post Period End Activity

Significant progress was made on the Monte Muambe rare earths project during the reporting period.

Monte Muambe PFS activities are currently focused on advanced metallurgical testing. A 100kg representative ore sample is currently undergoing mineralogical feed characterisation at SGS Lakefields in Canada, using some of the most advanced tools available including Electron Microprobe Analysis and TIMA-X analysis. Following this, metallurgical test work will initially be aimed at producing a high-grade Rare Earths concentrate in order to improve the economics of the Mixed Rare Earth Carbonate production process. The possible separation and recovery of fluorspar, another critical raw material present in the ore at Monte Muambe, will also be assessed. Flotation test results are expected in Q2 2024.

Separation of the 15 Rare Earths present at Monte Muambe from their ore, with a focus on Neodymium, Praseodymium, Terbium and Dysprosium, is a complex process. Metallurgy is a critical component of rare earths projects development. Beside process design and costing, key outputs will also include products specifications to enable discussions with potential off-takers.

Corporate Strategy Update

In February 2024, the Board of Directors undertook a careful and thorough review of the Company's corporate strategy. As Monte Muambe is advancing, Altona recognised that the time was right for the Company to expand and diversify its portfolio of projects in Africa, including Rare Earths, but also non-Rare Earths critical raw materials such as copper, lithium and niobium.

The Company is therefore currently actively assessing potential new opportunities, with the objective of selecting a small number of quality projects having a low-entry cost and a clear pathway to early results and to majority ownership.

The recently announced acquisition of the Kabompo South Copper project in Zambia, which was owned by Freeport McMoRan until the major's strategic decision to exit Zambia in 2020, is a first step in the implementation of this updated corporate strategy. Field activities will start in Q2 2024.

The Kabompo South project 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.

The project is located in the Mufumbe District of Northwestern Province, Zambia. It has a surface area of approximately 616 km2 and is valid for copper, cobalt, nickel, lead, zinc, gold and diamonds. Kabompo South is located 4 km west of the Kamweji copper occurrence, and 60 km southwest of the Mufumbwe copper deposit (22 million tonnes at 1.6% Cu), along strike.

As Altona moves forward with this strategy, the Company remains acutely aware of the necessity of conserving cash resources and protecting shareholder value.

Outlook

In 2024, Altona plans to continue derisking Monte Muambe through on-going mineralogical and metallurgical testwork, the results of which are expected to have a favourable impact on the project's economic parameters, but also through the licensing process.

As this progresses, the Company will continue considering possible alternatives for funding the project PFS, including actively seek a possible strategic investor.

To complement Monte Muambe, the Company will continue assessing opportunities to acquire a limited number of carefully selected critical raw materials projects to expand and diversify its portfolio, within its management and funding capacity. This is expected to enable the Company to maintain a higher proportion of money-in-the-ground, as well as to build more resilience and a stronger news flow. The Company will also continue ensuring its overheads costs structure is as lean as possible.

We believe that the above actions will improve Altona's risk profile and strengthen the Company's value proposition for its shareholders.

The principal activity of the Company and its subsidiaries (the "Group") is in Rare Earths and the exploration and the development of appropriate exploration projects, focusing on opportunities in Africa.

These condensed interim financial statements were approved for issue on 28 March 2024.

These condensed interim financial statements do not comprise statutory accounts within the meaning of section 434 of the Companies Act 2006. Statutory accounts for the year ended 30 June 2023 were approved by the board of directors on 24 October 2023 and delivered to the Registrar of Companies. The auditor's report on those financial statements was unqualified but did include a reference to the material uncertainty surrounding going concern, to which the auditors drew attention by way of emphasis of matter and did not contain a statement under s498 (2) - (3) of Companies Act 2006.

The Company's auditors have not reviewed these condensed interim financial statements.

Basis of Preparation

The financial statements have been prepared on a going concern basis. The Group's assets are not currently generating revenues, an operating loss has been reported and an operating loss is expected in the 12 months subsequent to the date of these financial statements. The Company has recently entered into a debt facility of £250,000 and will look to raise further funds within the next 12 months to complete Phase 3 of its project at Monte Muambe. The directors remain confident of making further cost savings and/or raising finance when required and, therefore, the directors consider it appropriate to prepare the financial statements on a going concern basis. The financial statements do not include the adjustments that would result if the Group were unable to continue as a going concern.

The accounting policies adopted are consistent with those of the previous financial year and corresponding interim reporting period. There were no new or amended accounting standards that required the Group to change its accounting policies. The directors also considered the impact of standards issued but not yet applied by the Group and do not consider that there will be a material impact of transition on the financial statements.

The Group's results are not subject to seasonal variations.
