Joint Venture with Anglo American

The joint venture's drilling campaign is led by our partners at Anglo American. Following the completion of an extensive ground mapping exercise over its Zambian tenements, the Anglo American/Arc joint venture commenced drilling in August 2024. Drilling initially focused on a new target approximately 1km east of the oxide occurrence at Cheyeza.

A soil anomaly identified by Anglo's sampling program was observed at a new target approximately one and a half kilometres east of the existing oxide occurrence at Cheyeza (as announced on 7 November 2024) and was verified by diamond drilling. Near surface mineralisation was confirmed by assay data from hole KCDD002 included 40.60m at 0.61% Cu from 22.25m down the hole, including 12.75m @ 1.20% Cu from 22.25m and 7.70m @ 1.72% Cu from 26.75m.

The KCDD002 assay results demonstrate the potential to add to the known extents of the oxide occurrences at Cheyeza, where similar high grade zones have been intersected and reported in the past. Historic hole CHDDE004 intersected 18m @ 2.35% Cu from 30.60m with a higher grade zone of 7.60m @ 4.15% Cu from 39m, and hole CHDDE060 intersected 39m @ 1.47% Cu with a higher grade zone of 10m @ 2.25% Cu from 41m.

Importantly and unlike the previously reported oxide occurrence which is characterised as being a remobilised copper oxide occurrence, the oxide mineralisation intersected in hole KCDD002 may be the result of weathering of sulphide mineralisation at source, which is supported by the presence of sulphide mineralisation below the oxide zone.

Two holes were drilled at the new target Nkwazhi that is located between Cheyeza and Muswema, testing a thickened Lower Roan unit in this part of the basin. The first hole intersected copper mineralisation of over 20m at the base of the Upper Roan along with anomalous nickel in a marker talc-schist unit in the Lower Roan, below which currently no further mineralisation has been observed. The second hole drilled 400m away did not intersect mineralisation.

The third target tested was approximately 4km to the south-east of Muswema where a second order soil geochemical anomaly is present.

Zambia Exploration Acquisition

Arc announced on 7 April 2025 that it had entered into a binding agreement to acquire the Chingola Project (Licence 38113-HQ-LEL) in the Zambian Copperbelt. Under the terms of the agreement, Arc's 100% owned Zambian subsidiary, Foreland Minerals Limited, will purchase the entire interest in the licence from Brxton Construction Limited. The agreement is subject to certain customary conditions such as the completion of satisfactory due diligence and the receipt of necessary consents and approvals for the transfer. The consideration for the acquisition comprises an initial cash payment of USD 50,000 and further staged payments, subject to specific exploration milestones and regulatory approvals, as follows:

• $25,000 in ordinary shares of Arc Minerals Ltd based on the preceding 20-day volume weighted average price ("Acquisition Shares"), due upon full satisfaction or waiver by Arc of all conditions precedent ("Completion") ("Completion Payment");
• $100,000 in cash and $150,000 in Acquisition Shares on the earlier of the commencement of a drilling programme or 24 months after Completion ("First Instalment");
• $50,000 in cash and $50,000 in Acquisition Shares falling due within 10 business days of establishing an economic JORC-compliant 500kt+ Cu resource ("Second Instalment");
• $50,000 in cash and $50,000 in Acquisition Shares falling due within 10 business days of completing and announcing a successful definitive feasibility study; and
• A 2% net smelter royalty, capped at $5M, with a right of first refusal in favour of Arc pursuant to a royalty agreement to be entered into on or before Completion.

Botswana Drilling Campaign

The first phase to the maiden exploration programme in the central part of licence PL135/2017 consisted of eight holes totalling 3,023m, of which 1,978m were drilled by reverse circulation ('RC') and 1,045m by core diamond drilling ('DD') methods. The drilling was completed on budget and on time.

Of the eight holes drilled, diamond drill hole ALV-DD-004 intersected 3m @1.29% CuEq within a broader 6m @ 0.82% CuEq. Six of the remaining seven holes drilled intersected elevated to anomalous copper mineralisation with initial observations of the core displaying similar geological, stratigraphic and structural settings to that of MMG's operating Zone 5 underground mine. Assay results from the remaining drill hole in respect of license PL162/2017 identified no significant intercepts. The full details of the drilling programme are set out in the announcements dated 14 November 2024 and 14 May 2025.

Prospecting licenses 135/2017 and 162/2017 were extended for an additional two years until 30 September 2026 in accordance with the notification received from the Department of Mines in Gaborone, Botswana.

Outlook

While the drilling campaign by the Anglo American / Arc joint venture was frustrated by a late start to drilling it nevertheless provided valuable data over the 5 holes drilled, especially with regard to the Cheyeza target, which will be prioritised for further drilling. In addition, we understand that targets where no work has historically been completed (particularly the Fwiji and Nyambwezu targets) will be prioritised going forward.

The period ahead promises to be an exciting time for exploration and growth for Arc Minerals including the planned work at the new Chingola acquisition, assuming the conditions precedent are fulfilled.

Furthermore, with the acceptance by the Botswanan Department of Mines of our applications to extend the licence terms of the PL135/2017 and PL162/2017 licenses, we expect to continue to explore and unlock the potential of the Virgo Project licenses for an additional two years, until 2026.

As we forge ahead, our shareholders can expect regular updates on the progress of our exploration activities, including the results of the geological studies, geophysical surveys, and, most importantly, the drilling campaigns. We remain committed to maintaining open and transparent communication, keeping you informed every step of the way.

NOTES TO THE FINANCIAL STATEMENTS

• Summary of Significant Accounting Policies
• General Information and Authorisation of Financial Statements

The Company is registered in the British Virgin Islands under the BVI Business Companies Act 2004 with registered number 1396532 and is located at Craigmuir Chambers, Road Town, Tortola. The Company's ordinary shares are traded on AIM, a market of the London Stock Exchange.

The principal activity of the Company during the year was that of a holding company for a group engaged in the identification, evaluation, acquisition and development of natural resource projects.

The Financial Statements of Arc Minerals Limited for the year ended 31 December 2024 were authorised for issue by the Board on 26 June 2025.

Basis of Preparation

The financial statements have been prepared in accordance with International Financial Reporting Standards (IFRS) and IFRS Interpretations Committee (IFRS IC) as adopted by the European Union.

The consolidated financial statements have been prepared on the historical convention, as modified by the measurement to fair value of financial assets through profit and loss and held for sale assets and liabilities as described in the accounting policies below.

The financial information is presented in Pounds Sterling (£) and all values are rounded to the nearest thousand Pounds Sterling (£000's) unless otherwise stated.

New and amended standards adopted by the Group

There were no new standards, amendments or interpretations effective for the first time for periods beginning on or after 1 January 2024 that had a material effect on the consolidated or company financial statements.

At the date of approval of these financial statements, there were no new standards or amendments to IAS which have not been applied in these financial statements which were in issue but not yet effective and are expected to have a material impact on the consolidated and company financial statements.

Basis of Consolidation

The Consolidated Financial Statements comprise the financial statements of the Company and its subsidiaries made up to 31 December. Control is achieved when the Group is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee.

• The contractual arrangement with the other vote holders of the investee;
• Rights arising from other contractual arrangements; and
• The Group's voting rights and potential voting rights

Subsidiaries

Subsidiaries are entities over which the Group has control. Subsidiaries are fully consolidated from the date on which control is transferred to the Group. They are deconsolidated from the date that control ceases. Assets, liabilities, income and expenses of a subsidiary acquired or disposed of during the year are included in the consolidated financial statements from the date the Group gains control until the date the Group ceases to control the subsidiary.

The consolidated financial statements consolidate the financial statements of Arc Minerals Limited and the audited financial statements of its subsidiary undertakings made up to 31 December 2024.

When necessary, adjustments are made to the financial statements of subsidiaries to bring their accounting policies into line with the Group's accounting policies. All intra-group assets and liabilities, equity, income, expenses and cash flows relating to transactions between members of the Group are eliminated in full on consolidation.

Associates are entities over which the Group has significant influence but not control, generally accompanying a shareholding of between 20% and 50% of the voting rights. Investments in associates are accounted for using the equity method of accounting. Under the equity method, the investment is initially recognised at cost and the carrying amount is increased or decreased to recognise the investor's share of the profit or loss of the investee after the date of acquisition. The Group's investment in associates includes any goodwill identified on acquisition.

Where the ownership interest in an existing investment is increased whereby significant influence is obtained, the Group re-measures the existing investment immediately prior to obtaining significant influence with resulting gains/losses recognised immediately in profit or loss. The fair value of the existing investment added to the fair value of the consideration of the additional investment is treated as the deemed cost and is continued to be accounted for under the equity method.

The Group's share of post-acquisition profit or loss is recognised in the statement of comprehensive income, and its share of post-acquisition movements is recognised in the other comprehensive income section of the statement of comprehensive income with a corresponding adjustment to the carrying amount of the investment. When the Group's share of losses in an associate equals or exceeds its interest in the associate, including any unsecured receivables, the Group does not recognise further losses, unless it has incurred legal or constructive obligations or made payments on behalf of the associate.

The Group determines at each reporting date whether there is any objective evidence that the investment in the associate is impaired. If this is the case, the Group calculates the amount of impairment as the difference between the recoverable amounts of the associate and its carrying value and recognises the amount adjacent to 'share of profit/loss of associate' in the group statement of comprehensive income.

When the Group loses significant influence over an associate, it derecognises that associate and recognises a profit or loss being the difference between the sum of the proceeds received and any retained interest, and the carrying amount of the investment in the associate at the date significant influence is lost.

Gains and losses resulting from upstream and downstream transactions between the Group and its associates are recognised in the Group's financial statements only to the extent of unrelated investor's interests in the associates. Unrealised losses are eliminated unless the transaction provides evidence of an impairment of the asset transferred. Accounting policies of associates have been changed where necessary to ensure consistency with the policies adopted by the Group.

Impairment gains and losses arising in investments in associates are recognised in the statement of comprehensive income.

When the Group gains control of an associate the fair value of the associate undertaking is then assessed with any gain or loss arising being recognised within the income statement.

Going Concern

The Directors have reviewed a forecast for the next 18 months, prepared by the executive and have a reasonable expectation that the Group has sufficient funds to continue in operation and satisfy liabilities for the foreseeable future.

Whilst the Group has sufficient funds to meet their day to day working capital needs for a period of 12 months from the date the financial statements are approved through a mix of reducing exploration spend and other expenses, along with the deferral of directors' fees, they will require further funding to finance its exploration programme in the medium term, which may include a fund raising in the future. The Directors note that the Group's ability to remain a going concern beyond the Going Concern assessment period of 12 months from the date the financial statements is approved is dependent on the Group's ability to raise further equity and/or debt finance in the medium term. Whilst the Directors acknowledge that this carries a degree of uncertainty, in part due to current market volatility, they have a reasonable expectation that the Group will continue to be able to raise finance as required.

The Directors therefore consider it appropriate for the Company to continue to adopt the going concern basis in preparing the Annual Report and Financial Statements.

Business combinations

The Group applies the acquisition method to account for business combinations. The consideration transferred for the acquisition of the subsidiary is the fair value of the assets transferred, the liabilities incurred to the former owners of the acquiree and the equity interests issued by the Group. The consideration transferred includes the fair value of any asset or liability resulting from a contingent consideration arrangement. Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are measured initially at their fair values at acquisition date. The Group recognises any non-controlling interest in the acquiree on an acquisition by acquisition basis; either at fair value or at the non-controlling interest's proportionate share of the recognised amounts of the acquiree's identifiable net asset.

Acquisition related costs are expensed as incurred.

If a business combination is achieved in stages, the acquisition date carrying value of the acquiree's previously held interest in the acquire is re-measured to fair value at the acquisition date; any gain or loss arising from such a re-measurement are recognised in profit or loss.

Goodwill is initially measured as the excess of the aggregate of the consideration transferred and the fair value of non-controlling interest over the identifiable net assets acquired and liabilities assumed. If this consideration is lower than the fair value of the net assets of the subsidiary acquired, the difference is recognised in profit or loss in the Income Statement.

Any interest of non-controlling interests in the acquiree is initially measured at the minority's proportion of the net fair value of the assets, liabilities and contingent liabilities recognised. There are no non- controlling shareholders of subsidiaries.

Segment reporting

Operating segments are reported in a manner consistent with the internal reporting provided to the Board, being the Group's chief operating decision-maker ("CODM").

Foreign currencies

The Group presentational currency is pound sterling (GBP). Each entity in the Group determines its own functional currency and items included in the financial statements of each entity are measured using that functional currency. At present the functional currency for the Zambian subsidiaries is the Zambian Kwacha ("ZMW"). The functional currency of the Botswana subsidiary is the Botswanan Pula (BWP). The functional currency for all other entities is GBP.

The presentational currency (GBP) is used primarily because the Parent Company Arc Minerals Limited is listed on AIM, a market of the London Stock Exchange, and raises its funding in GBP.

• monetary assets and liabilities for each balance sheet presented are translated at the closing rate at the date of that balance sheet;
• income and expenses are translated at average exchange rates during the accounting year; and
• all resulting exchange differences are recognised in other comprehensive income where material.

On consolidation, exchange differences arising from the translation of the net investment in foreign entities, and of monetary items receivable from foreign subsidiaries for which settlement is neither planned nor likely to occur in the foreseeable future are taken to other comprehensive income. When a foreign operation is sold, such cumulative exchange differences are subsequently reclassified in the income statement as part of the gain or loss on sale.

Taxation

Tax is recognised in the consolidated Statement of Comprehensive Income, except to the extent that it relates to items recognised in other comprehensive income or directly in equity. In this case, the tax is also recognised in other comprehensive income or directly in equity, respectively.

Deferred tax is accounted for using the balance sheet liability method in respect of temporary differences arising from differences between the carrying amount of assets and liabilities in the financial statements and the corresponding tax bases used in the computation of taxable profit. However, deferred tax liabilities are not recognised if they arise from the initial recognition of goodwill; deferred tax is not accounted for if it arises from initial recognition of an asset or liability in a transaction other than a business combination that at the time of the transaction affects neither accounting nor taxable profit or loss.

In principle, deferred tax liabilities are recognised for all taxable temporary differences and deferred tax assets are recognised to the extent that it is probable that taxable profits will be available against which deductible temporary differences can be utilised.

Deferred tax assets and liabilities are offset when there is a legally enforceable right to offset current tax assets against current tax liabilities and when the deferred tax assets and liabilities relate to taxes levied by the same taxation authority on either the same taxable entity or different taxable entities where there is an intention to settle the balances on a net basis.

Deferred tax is calculated at the tax rates that are expected to apply to the period when the asset is realised or the liability is settled. Deferred tax assets and liabilities are not discounted.

There has been no tax credit or expense for the year relating to current or deferred tax.

Intangible assets

Exploration and evaluation assets

Exploration and development costs are carried forward in respect of areas of interest where the consolidated entity's rights to tenure are current and where these costs are expected to be recouped through successful development and exploration, or by sale. Alternatively, these costs are carried forward while active and significant operations are continuing in relation to the areas of interest and it is too early to make reasonable assessment of the existence or otherwise of economically recoverable reserves. When the area of interest is abandoned, exploration and evaluation costs previously capitalised are impaired.

Costs incurred by the Company on behalf of its subsidiaries and associated with mining development and investment are capitalised on a project-by-project basis pending determination of the feasibility of the project. Costs incurred include appropriate technical and administrative expenses but not general overheads. If a mining development project is successful, the related expenditures will be written-off over the estimated life (useful economic life) of the commercial ore reserves on a unit of production basis. Impairment reviews are carried out regularly by the Directors of the Company. Where a project is abandoned or is considered to be of no further commercial value, the related costs will be written off to the Statement of Comprehensive Income.

The recoverability of these costs is dependent upon the discovery of economically recoverable reserves, the ability of the Group to obtain necessary financing to complete the development of reserves and future profitable production or proceeds from the disposal of recoverable reserves.

• Significant accounting judgements, estimates and assumptions

Critical Accounting Estimates and Judgements

Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognised prospectively from the period in which the estimates are revised. The following are the key estimate and assumption uncertainties that have a significant risk of resulting in a material adjustment within the next financial year:

• Valuation of exploration, evaluation and development expenditure

Exploration and evaluation assets held as intangible fixed assets on the statement of financial position comprises all costs which are directly attributable to the exploration of a project area. The Group recognises expenditure as exploration and evaluation assets when it determines that those assets will be successful in finding specific mineral resources. Expenditure capitalised as exploration and evaluation assets relates to the acquisition of rights to explore, topographical, geological, geochemical and geophysical studies, exploratory drilling, trenching, sampling and activities to evaluate the technical feasibility and commercial viability of extracting a mineral resource. Capitalisation of pre-production expenditure ceases when the mining property is capable of commercial production.

Valuation of Casa Royalty

There are a number of key factors which affect the valuation of the Casa Royalty which has a face value of US$ 45m (GBP 40m). These include (a) development and construction timeframe; (b) appropriate discount factor; (c) availability of construction financing; (d) political stability (e) gold price and (f) ability to control timing of receipt.

Given these uncertainties the Company has elected to assign nil value to the Royalty. The Company will reassess this carrying value in future as the Misisi Project progresses along the development curve.

Short term investments are measured initially, and subsequently revalued at reporting dates, at fair value through profit or loss. Similarly, changes in fair value are recognised through profit and loss. Additional information is contained in Note 17.

Investment in associate

The investment in associate arose as a result of the partial disposal in 2023 of Handa Resources Limited (Handa) as a subsidiary. The investment shareholding decreased from 66% (a subsidiary) to 30% (an associate). Unico lost control in a series of five contractual arrangements that were entered into for the purposes of the Joint Venture (JV) agreement with Anglo American BV. Consequently, single transaction accounting was applied in accounting for the transaction. See Note 14 for details of this agreement). The remaining investment, after the partial disposal of Handa, was fair valued as at the date of the disposal (See Note 13) and has been subsequently measured using the equity method at year end.

Regency recoverability

Whilst outstanding for some time, management believes, having made reasonable enquiries, that this remains recoverable.

Equity

Equity comprises the following:

• "Share capital" represents the nominal value of the Ordinary shares;
• "Share based payment reserve" represents stock options awarded by the group;
• "Warrant reserve" represents warrants granted by the group;
• "Foreign exchange reserve" represents the translation differences arising from translating the financial statement items from functional currency to presentational currency and foreign exchange differences arising on the elimination of intercompany loans forming part of the investment of subsidiaries;
• "Retained earnings" represents retained losses.
• "Non-controlling interest" represents the interests of minority shareholders in the assets and liabilities of the Group.
• Cash and cash equivalents

Cash and cash equivalents comprise current balances with banks and similar institutions and liquid investments generally with maturities of 3 months or less. They are readily convertible into known amounts of cash and have an insignificant risk of changes in value.

Trade and other receivables

Receivables are recognised initially at amortised cost, being their initial fair value. These are classified as loans and receivables and so are subsequently carried at amortised cost using the effective interest method. The Directors are of the view that such items are collectible and that no provisions are required.

• Financial instruments
• Classification

The Group classifies its financial assets at amortised cost and at fair value through the profit or loss or OCI. The classification depends on the purpose for which the financial assets were acquired. Management determines the classification of its financial assets at initial recognition

Recognition and measurement

Amortised cost

Fair value through the profit or loss

• Level 1: Quoted prices in active markets for identical items (unadjusted)
• Level 2: Observable direct or indirect inputs other than Level 1 inputs
• Level 3: Unobservable inputs (i.e. not derived from market data).

Listed investments are valued at closing bid price on 31 December 2024. For measurement purposes, financial investments are designated at fair value through the income statement. Gains and losses on the realisation of investments are recognised in the income statement for the period. The difference between the market value of financial instruments and book value to the Company is shown as a gain or loss in the income statement for the period.

• Impairment of financial assets
• Derecognition

Financial liabilities

Subsequent measurement

The measurement of financial liabilities depends on their classification, as described below:

Trade and other payables

After initial recognition, trade and other payables are subsequently measured at amortised cost using the Effective Interest Rate ("EIR") method. Gains and losses are recognised in the statement of profit or loss and other comprehensive income when the liabilities are derecognised, as well as through the EIR amortisation process.

Derecognition

Fair value measurement

IFRS 13 establishes a single source of guidance for all fair value measurements. IFRS 13 does not change when an entity is required to use fair value but rather provides guidance on how to measure fair value under IFRS when fair value is require or permitted. The resulting calculations under IFRS 13 affected the principles that the Company uses to assess the fair value, but the assessment of fair value under IFRS 13 has not materially changed the fair values recognised or disclosed. IFRS 13 mainly impacts the disclosures of the Company. It requires specific disclosures about fair value measurements and disclosures of fair values, some of which replace existing disclosure requirements in other standards.

Property, plant and equipment

Property, plant and equipment is stated at cost less accumulated depreciation and any accumulated impairment losses.

Depreciation is provided on all property, plant and equipment to write off the cost less estimated residual value of each asset at 25% on a straight-line basis.

Property, plant and equipment are tested for impairment if events or changes in circumstances (assessed at each reporting date) indicate that the carrying amount may not be recoverable.

Impairment of assets

The Group assesses at each reporting date whether there is an indication that an asset may be impaired. If any such indication exists, or when annual impairment testing for an asset is required, the Group makes an estimate of the asset's recoverable amount.

An asset's recoverable amount is the higher of its fair value less costs to sell and its value in use. This is determined for an individual asset, unless the asset does not generate cash inflows that are largely independent of those from other assets or groups of assets, and the asset's value in use cannot be estimated to be close to its fair value. In such cases, the asset is tested for impairment as part of the cash-generating unit to which it belongs. When the carrying amount of an asset or cash-generating unit exceeds its recoverable amount, it is considered impaired and is written down to its recoverable amount.

In assessing value in use, estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset. Impairment losses relating to continuing operations are recognised in those expense categories consistent with the function of the impaired asset, unless the asset is carried at revalued amount (in which case the impairment loss is treated as a revaluation decrease).

An assessment is also made at each reporting date as to whether there is any indication that previously recognised impairment losses may no longer exist or may have decreased. If such indication exists, the recoverable amount is estimated. A previously recognised impairment loss is reversed only if there has been a change in the estimates used to determine the asset's recoverable amount since the last impairment loss was recognised. If that is the case, the carrying amount of the asset is increased to its recoverable amount. That increased amount cannot exceed the carrying amount that would have been determined, net of depreciation, had no impairment loss been recognised for the asset in prior years. Such reversal is recognised in the Statement of Comprehensive Income unless the asset is carried at revalued amount, in which case the reversal is treated as a revaluation increase. After such a reversal, the depreciation charge is adjusted in future periods to allocate the asset's revised carrying amount, less any residual value, on a systematic basis over its remaining useful life.

Share-based payments

The Group provides benefits to senior personnel, consultants and advisors of the Group in the form of share-based payments, whereby such parties render services in exchange for shares or rights over shares (equity-settled transactions).

The cost of these equity-settled transactions with such parties is measured by reference to the fair value of the equity instruments at the date at which they are granted. The fair value is determined by using a Black-Scholes model.

In valuing equity-settled transactions, no account is taken of any performance conditions, other than conditions linked to the price of the shares of Arc Minerals Limited (market conditions) if applicable.

The cost of equity-settled transactions is recognised, together with a corresponding increase in equity, over the period in which the performance and/or service conditions are fulfilled, ending on the date on which the relevant party become fully entitled to the award (the vesting period).

The cumulative expense recognised for equity-settled transactions at each reporting date until vesting date reflects:

• the extent to which the vesting period has expired, and;
• the Group's best estimate of the number of equity instruments that will ultimately vest.

No adjustment is made for the likelihood of market performance conditions being met, as the effect of these conditions is included in the determination of fair value at grant date. The charge to the Income Statement for a period represents the movement in cumulative expense recognised as at the beginning and end of that period.

No expense is recognised for awards that do not ultimately vest, except for awards where vesting is only conditional upon a market condition.

Upon expiry, the associated portion of the share option reserve is derecognised and recorded against retained losses.

The dilutive effect, if any, of outstanding options is reflected as additional share dilution in the computation of earnings/ (loss) per share.

Basic EPS is calculated as profit attributable to equity holders of the parent for the period, adjusted to exclude any costs of servicing equity (other than dividends), divided by the weighted average number of ordinary shares, adjusted for any bonus element. Fully-diluted EPS adjusts Basic EPS to reflect the impact if all share purchase warrants and options were exercised.

• Borrowings
• Segmental analysis

Segment information has been determined based on the information reviewed by the Board for the purposes of allocating resources and assessing performance. No revenue is currently being generated.

Head office activities are administrative in nature whilst the activities in Zambia and Botswana relate to exploration and development work.

Segment results, assets and liabilities include items directly attributable to a segment as well as those that can be allocate on a reasonable basis.

Auditors Remuneration

During the year, the Group obtained the following services from the Company's auditor:

Employee information

The average number of persons employed in the Group through payroll was nil (2023 - nil) at a cost of nil (2023 - nil). See Note 7 for details of key management remuneration.

Disposals of held for sale assets

Handa Disposal as part of Anglo Joint Venture

On 12 May 2022 the Company announced that it, together with its partners, had entered into an agreement with Anglo American with the intention to form a joint venture in respect of its Zambian copper interests. The key commercial terms of the Joint Venture were that, upon signing of a binding Joint Venture Agreement ("JV Agreement"), Anglo American would have an initial ownership interest of 70% with Arc and its partners holding the balance via Unico Minerals Ltd ("Unico") in which Arc will have a 67% interest with the balance held by its partners. On 20 April 2023, the JV Agreement was signed subject to completing certain conditions precedent including a restructuring of the Group's assets, obtaining approvals from relevant government and regulatory authorities and other customary conditions. On 10 November 2023 (the Effective Date), the Company satisfied the Conditions Precedent (see Note 14).

The related financial information is set out below:

Results of disposal group prior to disposal

Taxation reconciliation

The charge for the year can be reconciled to the loss per the consolidated statement of comprehensive income:

The weighted average applicable tax rate of 6.2% (2023: 25.20%) used is a combination of the 0% corporation tax in the BVI (2023:0%), 30% corporation tax in Zambia (2023: 30%) and 22% corporation tax in Botswana (2023: 22%).

A deferred tax asset has not been provided for in accordance with IAS 12 due to uncertainty as to when profits will be generated against which to relieve any such asset. The Group does not have a material deferred tax liability at the year end.

The tax rate used is the weighted average rate of the British Virgin Islands, the Republic of Botswana and the Republic of Zambia (up to the date of the disposal of the Zambian subsidiaries). Unused taxable losses available in Botswana approximate BWP 1.563M (£91k) at 31 December 2024 (31 December 2023 - BWP 367k (£22k)).

Unico distributed to its shareholders £789k (31 December 2023 £2,863k) of which 67% £ 528k (31 December 2023 £1,918) was distributed to the Company on 27 November 2024. The net difference of £261k (31 December 2023 £945k) was the distribution to Unico's minority shareholder.

Key management remuneration

• Includes contractual notice with respect to R Welschinger's former office as Finance Director.
• C Mulenga resigned effective 27 March 2023.
• I Lynch was appointed to the office of Chief Financial Officer in November 2023.
• This represents 50% of bonuses declared in 2023 on a deferred basis with the balance payable in 2024, in cash or in shares at the discretion of Management.
• Earnings (loss) per share

The calculation of Earnings per share is based on the profit/ (loss) attributable to equity holders divided by the weighted average number of shares in issue during the year.

• Due to the loss in 2024, the effect of options and warrants in calculating a diluted loss per share would be anti-dilutive and was therefore not calculated.
• The potential diluted weighted average number of shares as at 31 Dec 2023 has been corrected for a clerical error and the relevant diluted net earnings per share for the year ended 31 Dec 2023 has been restated.
• Long term payables

• The minority shareholder loans are payable to the minority shareholder Alvis-Crest (Proprietary) Limited in the amount of BWP 1,797,430 (GBP 103k), as at 31 December 2024 (31 December 2023: BWP 1,797,430 (GBP 105k)). The loans are unsecured and loan holders have agreed to roll forward the loans until a liquidity event occurs.
• The minority shareholder loans rank equally with Arc's working capital loan to Alvis-Crest of BWP 23,231,411 (GBP 1.327M) (31 December 2023: BWP 12,055,723 (GBP 704k)), which is eliminated on consolidation. The loans are unsecured and loan holders have agreed to roll forward the loans until a liquidity event occurs.
• Intangible assets

The Group's Intangible assets are comprised of evaluation and exploration rights and exploration expenses with respect to the licences in Botswana.

The exploration project in Botswana is at an early stage of development and there is no JORC (Joint Ore Reserves Committee) or non-JORC compliant resource estimates available to enable value in use calculations to be prepared.

The Directors have undertaken a review to assess whether circumstances exist which could indicate the existence of impairment as follows:

• The Group no longer has title to mineral leases.

Following their assessment, the Directors concluded that no impairment indicators exist which would require a formal impairment assessment and therefore that no impairment has been recognised.

Fixed Assets

Investment in subsidiary and associate companies

At 31 December 2024, the Company held interests in the share capital of the following subsidiary and associate companies.

Unico Minerals Limited registered office at Craigmuir Chambers, Road Town, Tortola, British Virgin Islands, VG 1110.

Handa Resources Limited registered office at Plot No. 1266, Haile Selassie Avenue, Longacres, Lusaka, Zambia - Handa was a subsidiary of the Company until it was disposed as part of the joint venture agreement to Anglo American Exploration BV - see Note 14.

Alvis Crest (Proprietary) Limited is registered at Desert Secretarial Services (Pty) Limited, Plot 64518, Deloitte House, Fairground, PO Box 211008, Bontleng, Gaborone, Botswana.

Copala Holdings Limited registered office at Craigmuir Chambers, Road Town, Tortola, British Virgin Islands, VG 1110.

Foreland Minerals Limited registered office at Plot No. A5562, Chamba Valley, Lusaka, Zambia.

The non-controlling interest shown within the primary statement arises as a result of the Group owning less than 100% of a subsidiary company.

Investment in Associate

The Investment in Associate comprises of the investment in Handa Resources Limited (Group), being the vehicle for the joint venture with Anglo American BV ("Anglo"), which was acquired on 10 November 2023 following satisfaction of all conditions precedent. Details of the joint venture are set out in Note 14.

Anglo's accounting policy requires exploration expenditure to be expensed through profit and loss. As such, the share of losses includes the Group's share of exploration expenditure incurred during the period 1 January to 31 December 2024.

During 2023, the Group submitted three mining license applications as part of preparing for completion of the JV with a subsidiary of Anglo American, being 33402-HQ-LML, 33403-HQ-LML and 33404-HQ-LML over the exploration licenses 23004-HQ-LEL and 19906-HQ-LEL. All of the mining licence applications were approved and validated by the Mining Cadastre Department and, following submission of the subsequent requisite documentation, the Mines Advisory Committee (MAC) was expected to meet to review the finalised LML applications prior to issuance of the Mining Licenses.

As announced on 17 June 2024, the Mining Cadastre Department published the results of the MAC meeting pursuant to which these applications and were rejected and Zaco Investments Limited's application with respect to 23004-HQ-LEL was marked as deferred pending an information request. As the applications were validly submitted and validated by the Zambian Mining Cadastre, the Company has been advised that Handa and Zaco will be appealing the decision of the Mining Licence Committee to reject the Mining Licence Applications and are engaging with the Mining Cadastre to have the appeal heard as soon as possible so that the applications can be reinstated and/or considered positively in accordance with the law.

With the exception of the licence mentioned above, none of the Company's other licences were affected by the recent Mining Licence Committee Meeting review and Anglo continued to mobilise for the planned exploration activities.

Joint Venture Agreement with Anglo American

On 12 May 2022 the Company announced that it, together with its partners, had entered into an agreement with Anglo American with the intention to form a joint venture in respect of its Zambian copper interests. The key commercial terms of the Joint Venture were that, upon signing of a binding Joint Venture Agreement ("JV Agreement"), Anglo American would have an initial ownership interest of 70% with Arc and its partners holding the balance via Unico Minerals Ltd ("Unico") in which Arc will have a 67% interest. On 20 April 2023, the JV Agreement was signed subject to completing certain conditions precedent including a restructuring of the Group's assets, obtaining approvals from relevant government and regulatory authorities and other customary conditions. On 10 November 2023 (the "Effective Date"), the Company announced that it had satisfied the conditions precedent. The key commercial terms of the Joint Venture are as follows:

Handa Resources Limited - the Joint Venture vehicle - was reconstituted to reflect the initial ownership interests of Anglo American and Unico of 70% and 30%, respectively ("Initial Ownership Interests");

• Anglo American has the right to retain an Ownership Interest of 51%, by:

funding exploration expenditures equal to USD 24,000,000 on or before the date that is 180 days after the third anniversary of the Effective Date ("Phase I End Date"); and making cash payments to Unico totalling up to USD 14,500,000, as follows:

• USD 3,500,000, which was received on 13 November 2023;
• USD 1,000,000, which was received on 27 November 2024;
• The balance receivable of USD 11M becomes due as follows:

o USD 1,000,000 on the second anniversary of the Effective Date;

o USD 1,000,000 on the third anniversary of the Effective Date; and

o USD 8,000,000 by the Phase I End Date.

Following the completion of Phase I, Anglo American will have the right to retain an additional ownership interest equal to 9% (for a total ownership interest of 60%) by funding USD 20,000,000 of additional exploration expenditures within 2 years of the Phase I End Date ("Phase II End Date")

Following the completion of Phase II, Anglo American will have the right to retain an additional ownership interest equal to 10% (for a total ownership interest of 70%) by funding USD 30,000,000 within 2 years of the Phase II End Date ("Phase III End Date").

During the period up to the Phase III End Date, 30% of the total funds contributed by Anglo will be deemed to have been contributed by Unico Minerals Limited ("Deemed Contribution"). The Deemed Contribution is not reflected in these accounts and will be fully calculated and reconciled with the records of Handa at the end of each phase of the JV.

Anglo American, for as long as it holds the largest interest in the Joint Venture, shall have the right to nominate three directors and Unico shall have the right to nominate two directors. Joint Venture board decisions shall be adopted by simple majority vote.

Details of the group's gain on disposal of the Zaco and Handa subsidiaries is as follows:

Group

31 Dec 2023 £ 000's

Following the transaction with Anglo, the group's interest in Handa reduced to 30% and as part of the disposal accounting, the directors assessed that their interest in Handa would be accounted for an investment in associate and the value of the investment amounted to £3.149m that they have deemed on recognition.

Receivables

Receivable - Anglo JV

The £798k is due in November 2025, being the sterling equivalent of the net present value of USD 1M receivable upon the second anniversary of the Effective Date of the Anglo JV. A long-term receivable component of £6.261M has been recognised, representing the net present value of the remaining USD 9M proceeds arising from the Anglo JV agreement by the Phase I End Date. The total proceeds had a nominal value of USD 14.5M and was discounted at a rate of 5.5% and a USD/GBP exchange rate of £ 0.80. See Note 14 for details of amounts receivable pursuant to the joint venture agreement with Anglo American.

Receivable - Casa Sale

Included in receivables at 31 December 2024 is £999k (USD 1.25M) (2023: £982k (USD1.25M)) to reflect the overdue Consideration Shares due to Arc in relation to the disposal of Casa Mining Limited:

As announced on 29 April 2022, Regency Mining Ltd ("Regency") acquired a 73.5% interest in the Misisi gold project ("Misisi Project") from Golden Square Equity Partners Limited ("Golden Square"), replacing Rackla Metals Inc. as the acquiror of Misisi. The terms of the transaction were that Arc would be paid USD 250,000 in cash and the equivalent of USD 1,250,000 in shares in a publicly listed company in Canada ("Consideration Shares"). The agreement also provided Arc with a royalty agreement on the same terms as the previous royalty agreement announced on 5 May 2021.

On 30 June 2023, the Company received the first cash payment of USD 125,000 towards the USD 1,500,000 receivable from the disposal of its Casa interests. On 12 September 2023, the Company received the second cash payment of USD 125,000, bringing the aggregate cash payments received by the Company to date to USD 250,000. The balance of USD 1,250,000 is to be settled by the issuance of listed stock which has been delayed due to corresponding delays in the listing process of the underlying entity. Management continues to follow up on progress and the directors consider the balance recoverable.

Royalties

Net Smelter Royalty - Casa Mining Ltd

On 18 March 2020 the Company announced the sale of its shareholding in Casa Mining Limited in return for a USD 5,000,000 interest-free note originally payable on 19 March 2021 and a 3% Royalty calculated on net smelter production capped at USD 45,000,000. The USD 5m loan note was subsequently extended and, as announced in the RNS dated 29 April 2022, satisfied in full.

There were a number of key factors which affect the valuation of the Casa Royalty which has a face value of USD 45,000,000. These include (a) development and construction timeframe; (b) appropriate discount factor; (c) availability of construction financing; (d) political stability and (e) gold price.

Given these uncertainties the Company has elected to assign nil value to the Royalty. The Company will reassess this carrying value in future as the Misisi Project progresses along the development curve.

• Short-term Investments Held at Fair Value Through Profit and Loss

The Group's investments held at fair value through profit and loss consist of investments publicly traded on the London Stock Exchange and the Over-The-Counter (OTC) market. These investments are valued at the mid-price as at year end.

Losses on short-term investments held at fair value through profit and loss

The fair value Agri-Fintech Holdings Inc. (TMNA), formerly Tingo Inc., declined significantly in 2023. The fair value losses recognised represent the decline in value. Amid widely publicised FBI and SEC investigations, TMNA announced its intention to liquidate in the fourth quarter of 2023. Following this announcement, the investment was impaired in full. The Company continues to monitor developments.

Financial instruments and capital risk management

Categories of financial instruments

The categories of financial assets and liabilities included in the statement of financial position are as follows:

Financial Risk Management

Financial Risk Factors

Risk management is carried out by the Board of Directors under policies approved at Board meetings. The Board frequently discusses principles for overall risk management including policies for specific areas such as foreign exchange.

• Market Risk
• Foreign Exchange Risk

The Group operates internationally and is exposed to foreign exchange risk arising from various currency exposures, primarily with respect to the pound sterling, US dollar ("USD"), Zambian kwacha ("ZMW") and Botswanan pula ("BWP"). Foreign exchange risk arises from recognised monetary assets and liabilities, where they may be denominated in a currency that is not the Group's functional currency.

The Zambian kwacha depreciated by approximately 7% (51% in 2023) - it has shown to be a volatile currency. The kwacha risk is mitigated by the fact that the Group's Zambian entities were disposed of during 2023 - See Note 14. The Group's exposure is limited to Foreland Minerals Limited subsidiary.

The Botswanan pula depreciated by approximately 2% (appreciated 11% in 2023), Whilst less volatile than the ZMW, the pula risk is similarly mitigated to that of the kwacha by the fact that the Group's Botswanan entity would only have one month's cash requirement on hand at any one time.

On the assumption that all other variables were held constant, and in respect of the Group and the Company's expenses the potential impact of a 20% increase/decrease in the GBP:ZMW foreign exchange rate on the Group's loss for the year and on equity is as follows:

Potential impact on Zambian kwacha and Botswanan Pula expenses: 2023

Potential impact on Zambian kwacha and Botswanan pula expenses: 2024

Increase/(decrease) in exchange rates

Credit Risk

Credit risk arises from cash and cash equivalents.

The Group considers the credit ratings of banks in which it holds funds in order to reduce exposure to credit risk. The Group will only keep its holdings of cash and cash equivalents with reputable institutions.

The Group considers that it is not exposed to major concentrations of credit risk.

The Group holds cash as a liquid resource to fund its obligations. The Group's cash balances are held primarily in USD. The Group's strategy for managing cash is to assess opportunity for interest income whilst ensuring cash is available to match the profile of the Group's expenditure. This is achieved by regular monitoring of interest rates and monthly review of expenditure forecasts. Short term interest rates on deposits remained very unattractive during the fiscal year and management employed short-term investment strategies to protect working capital reserves.

The Group has a policy of not hedging and therefore takes market rates in respect of foreign exchange risk; however, it does review its currency exposures on an ad hoc basis. Currency exposures relating to monetary assets held by foreign operations are included within the foreign exchange reserve in the Group Balance Sheet.

The currency profile of the Group's cash and cash equivalent is as follows:

On the assumption that all other variables were held constant, and in respect of the Group's cash position, the potential impact of a 20% increase in the GBP:USD foreign exchange rate would not have a material impact on the Group's cash position and as such is not disclosed.

Liquidity Risk

To date the Group has relied upon equity funding to finance operations. The Directors are confident that adequate funding will be forthcoming with which to finance operations. Controls over expenditure are carefully managed.

The Group ensures that its liquidity is maintained by a management process which includes projecting cash flows and considering the level of liquid assets in relation thereto, monitoring Balance Sheet liquidity and maintaining funding sources and back-up facilities.

Listed securities

Fair value hierarchy

Level 1: quoted (unadjusted) prices in active markets for identical assets.

Level 3: techniques that use inputs that have a significant effect on the recorded fair value that are not based on observable market such as industry knowledge and experience of the Directors.

Risk arises from uncertainty about the future valuations of financial instruments held in accordance with the Company's investment objectives. These future valuations are determined by many factors but include the operational and financial performance of the underlying investee companies, as well as market perceptions of the future of the economy and its impact upon the economic environment in which these companies operate.

As at year end, the Company held no investments in companies that are listed on stock markets.

Capital Risk Management

The Group's objectives when managing capital are to safeguard the Group's ability to position as a going concern and to continue its exploration and evaluation activities. The Group has capital, defined as the total equity and reserves of the Group, of £11,448,000 (December 2023: £10,547,000).

The Group monitors its level of cash resources available against future planned exploration and evaluation activities and issues new shares in order to raise further funds from time to time.

Commitments

Alvis-Crest committed exploration expenditure

Until a decision to mine is reached, the Group is committed to spending, during any consecutive three year period, not less than USD 200,000 per year, on average, on the Virgo Project. The licences were renewed in 2024 for a further 2 years to 2026. The Group is committed to spending at least USD 200,000 over any consecutive 3 year period.

Exploration commitments

Ongoing exploration expenditure is required to maintain title to the Group's mineral exploration permits. No provision has been made in the Group financial statements for these amounts as the expenditure is expected to be fulfilled in the normal course of the operations of the Group.

Related party transactions

Transactions between the Company and its subsidiaries, which are related parties, have been eliminated on consolidation and are not disclosed in this note. There were no other transactions with related parties during the reporting year, except as disclosed below:

Remuneration of Key Management Personnel

The remuneration of the Directors and PDMRs is set out in Note 7.
