Accounting Policies, Changes In Accounting Estimates And Errors [Abstract]
Accounting Policies	ACCOUNTING POLICIES BASIS OF PREPARATION The principal accounting policies applied in the preparation of the consolidated financial statements have been consistently applied in all years presented except for the changes as described under "Recent accounting developments" below. The consolidated financial statements have been prepared in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board (IASB) and IFRS Interpretations Committee (IFRIC) Interpretations (collectively IFRS). The consolidated financial statements have been prepared on a going concern basis. The consolidated financial statements have been prepared to the nearest million and rounding may cause differences. RECENT ACCOUNTING DEVELOPMENTS New standards, amendments to standards and interpretations to existing standards adopted by the group During the financial year, the following new standards, amendments to standards and interpretations to existing standards were adopted by the group. No other standards and amendments to standards that became effective during the 2020 year had a material impact on the consolidated financial statements. Impact of the adoption of IFRS 16 Leases Scope of IFRS 16 IFRS 16 replaces the previous accounting standard on leases, IAS 17 Leases and related Interpretations. The new standard introduces a single lease accounting model and requires a lessee to capitalise most leases with certain exemptions. A lessee is required to recognise a right-of-use asset representing its right to use the underlying leased asset and a lease liability representing its obligation to make lease payments. Transition The group has elected to apply IFRS 16 utilising the modified retrospective approach, under which the cumulative effect of adopting the new standard is recognised as an adjustment to the opening balance of retained earnings at 1 July 2019 with no restatement of comparative information. The cumulative effect of adopting the standard had no impact on opening retained earnings and resulted in the recognition of right-of-use assets, lease liabilities and the resultant deferred tax. The group has reassessed all contracts in determining the lease population. Refer to note 28 for details on the amount of right-of-use assets and lease liabilities recognised as well as the incremental borrowing rates used. Transition options • The group has elected to recognise the right-of-use assets at an amount equal to the lease liability at 1 July 2019 together with the ability to set off deferred tax assets and liabilities resulting from the leased assets and liabilities. The lease liabilities were measured at the present value of the remaining lease payments at 1 July 2019 and discounted using the relevant incremental borrowing rate; and • The accounting for operating leases with a remaining lease term of less than 12 months as at date of adoption have been classified as short-term leases and have not been recorded on the balance sheet. 2 ACCOUNTING POLICIES continued RECENT ACCOUNTING DEVELOPMENTS continued New standards, amendments to standards and interpretations to existing standards adopted by the group continued Impact of the adoption of IFRS 16 Leases continued Practical expedients applied • The low value lease exemption - the group has elected to take the low value exemption with a value of R50 000 for the individual leased asset value and also applied its accounting policy on capitalisation of assets based on IAS 1 materiality assessment; • The short-term lease exemption - leases with a duration of less than a year will be expensed in the income statement on a straight-line basis ; • Use of hindsight, such as in determining the lease term if the contract contains options to extend or terminate the lease where appropriate; • Non-lease components - the group has applied the practical expedient not to separate non-lease components from lease components, and instead account for each lease component and any associated non-lease components as a single lease component for the classes of underlying asset where it is appropriate to do so; and • Exclusion of initial direct costs for the measurement of the right-of-use asset at the date of initial application. Accounting policy The leases accounting policy is applicable from 1 July 2019. Refer to note 28 for the policy. IFRS 16 Leases (Amendment) On 1 June 2020, the IASB issued COVID-19-Related Rent Concessions, which amended IFRS 16 Leases.The amendment permits lessees, as a practical expedient, not to assess whether particular rent concessions occurring as a direct consequence of the COVID-19 pandemic are lease modifications and instead to account for those rent concessions as if they are not lease modifications. The amendment does not affect lessors. To provide the practical expedient when needed most, the IASB enabled immediate application of the amendment in any financial statements—interim or annual—not authorised for issue at the date the amendment was issued. The amendments did not have a material impact on the group. IAS 19 Employee Benefits (Amendment) The amendments require an entity to use the updated assumptions from a remeasurement of net defined benefit liability or asset resulting from a plan amendment, curtailment or settlement to determine current service cost and net interest for the remainder of the reporting period after the change to the plan. The amendments apply for annual periods beginning on or after 1 January 2019. The amendments did not have a material impact on the group. IAS 23 Borrowing Costs (Amendment) The amendments clarify that if any specific borrowing remains outstanding after the related asset is ready for its intended use or sale, that borrowing becomes part of the funds that an entity borrows generally when calculating the capitalisation rate on general borrowings.The amendments apply for annual periods beginning on or after 1 January 2019. The amendments did not have a material impact on the group. IAS 28 Investments in Associates and Joint Ventures (Amendment) The amendments clarify that an entity applies IFRS 9 to long-term interests in an associate and joint venture that form part of the net investment in the associate or joint venture but to which the equity method is not applied. The amendments apply for annual periods beginning on or after 1 January 2019. The amendments did not have a material impact on the group. IFRIC 23 Uncertainty over Income Tax Treatments The interpretation specifies how an entity should reflect the effects of uncertainties in accounting for income taxes and is effective for annual periods beginning on or after 1 January 2019. IFRIC 23 specifically clarifies how to incorporate this uncertainty into the measurement of tax as reported in the consolidated financial statements. The interpretation does not introduce any new disclosures but reinforces the need to comply with existing disclosure requirements about judgements made, assumptions and other estimates used and the potential impact of uncertainties that are not reflected. The interpretation did not have a material impact on the group. 2 ACCOUNTING POLICIES continued RECENT ACCOUNTING DEVELOPMENTS continued New standards, amendments to standards and interpretations to existing standards that are not yet effective and have not been early adopted At the date of authorisation of these financial statements, the standards, amendments to standards and interpretations listed below were in issue but not yet effective. These new standards and interpretations have not been early adopted by the group and the group plans on adopting these standards, amendments to standards and interpretations on the dates when they become effective. IFRS 3 Business Combinations (Amendment) These amendments are effective for annual periods beginning on or after 1 January 2020 and make it easier for companies to decide whether activities and assets they acquire are a business or merely a group of assets. The amendments: • Confirm that a business must include inputs and a process, and clarified that: (i) the process must be substantive and (ii) the inputs and process must together significantly contribute to creating outputs; • Narrow the definitions of a business by focusing the definition of outputs on goods and services provided to customers and other income from ordinary activities, rather than on providing dividends or other economic benefits directly to investors or lowering costs; and • Add a test that makes it easier to conclude that a company has acquired a group of assets, rather than a business, if the value of the assets acquired is substantially all concentrated in a single asset or group of similar assets . All acquisitions going forward will be assessed using these amendments. Refer to note 12 . The amendments are not expected to have a material impact on the group. IFRS 7 Financial Instrument: Disclosures and IFRS 9 Financial Instruments (Amendment) The IASB issued an amendment to IFRS 9, IAS 39 and IFRS 7 insofar as they are affected by the Interest Rate Benchmark Reform and uncertainty during the reform period. The amendment addresses only the following hedge accounting requirements that are based on a forward-looking analysis: • The highly probable requirement; • Prospective assessments; and • Separately identifiable risk components. The amendments also require companies to provide additional information to investors about their hedging relationships which are directly affected by these uncertainties. Other than these specific amendments, the hedge accounting requirements would be unchanged. This amendment is effective for annual periods beginning on or after 1 January 2020. The amendments are not expected to have a material impact on the group. IFRS 7 Financial Instrument: Disclosures and IFRS 9 Financial Instruments (Amendment) The IASB has published 'Interest Rate Benchmark Reform - Phase 2 (Amendments to IFRS 9, IAS 39, IFRS 7, IFRS 4 and IFRS 16)' with amendments that address issues that might affect financial reporting during the reform of an interest rate benchmark, including the effects of changes to contractual cash flows or hedging relationships arising from the replacement of an interest rate benchmark with an alternative benchmark rate (replacement issues). The amendments are effective for annual periods beginning on or after 1 January 2021, with earlier application permitted. Harmony is still assessing the impact of this amendment. IFRS 9 Financial Instruments (Amendment) The amendment to IFRS 9 clarifies the fees a company includes when assessing whether the terms of a new or modified financial liability are substantially different from the terms of the original financial liability. This amendment is effective for annual periods beginning on or after 1 January 2022. The amendment is not expected to have a material impact on the group. IAS 1 Presentation of Financial Statements (Amendment) The IASB issued amendments to IAS 1 Presentation of Financial Statements to clarify its requirements for the presentation of liabilities in the statement of financial position. The amendments are effective from annual reporting periods beginning on or after 1 January 2023. The amendments are not expected to have a material impact on the group. IAS 1 Presentation of Financial Statements and IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors (Amendment) The amendments, effective for annual periods beginning on or after 1 January 2020, clarify and align the definition of "material" and provide guidance to help improve consistency in the application of materiality whenever it is used in IFRS Standards. 2 ACCOUNTING POLICIES continued RECENT ACCOUNTING DEVELOPMENTS continued New standards, amendments to standards and interpretations to existing standards that are not yet effective and have not been early adopted continued IAS 16 Property, Plant and Equipment (Amendment) The IASB issued Property, Plant and Equipment—Proceeds before Intended Use, which prohibit a company from deducting from the cost of property, plant and equipment amounts received from selling items produced while the company is preparing the asset for its intended use. Instead, a company will recognise such sales proceeds and related cost in profit or loss. This amendment is effective for annual periods beginning on or after 1 January 2022. Management is currently assessing the impact this would have on the group. IAS 37 Provisions, Contingent Liabilities and Contingent Assets (Amendment) The IASB issued Onerous Contracts–Cost of Fulfilling a Contract, which specifies which costs an entity includes in determining the cost of fulfilling a contract for the purpose of assessing whether the contract is onerous. This amendment is effective for annual periods beginning on or after 1 January 2022. The amendment is not expected to have a material impact on the group. MEASUREMENT BASIS The financial statements have been prepared under the historical cost convention except for certain financial assets and financial liabilities which are measured at fair value through profit or loss or other comprehensive income - refer to note 37 . GROUP ACCOUNTING POLICIES Accounting policies are included in the relevant notes to the consolidated financial statements and have been highlighted between red lines in the notes to the consolidated financial statements. The accounting policies that follow are applied throughout the financial statements. Consolidation The group recognises that control is the single basis for consolidation for all types of entities in accordance with IFRS 10 – Consolidated Financial Statements. The consolidated financial information includes the financial statements of the company, its subsidiaries, interest in associates and joint arrangements and structured entities. Where the group has no control over an entity, that entity is not consolidated. Control The group, regardless of the nature of its involvement with an entity, shall determine whether it is a parent by assessing whether it controls the investee. The group controls an entity when it is exposed, or has rights, to variable returns from its involvement with the entity and has the ability to affect those returns through its power to direct the activities of the entity. (i) 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 up until when that control ceases. Intercompany transactions, balances and unrealised gains on transactions between group companies are eliminated. Unrealised losses are also eliminated. Accounting policies of subsidiaries have been changed to ensure consistency with the policies adopted by the group. The group uses the acquisition method of accounting to account for business combinations. The consideration transferred for the acquisition of an acquiree is the fair value of the assets transferred, liabilities incurred 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. Acquisition-related costs are expensed as incurred. Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are measured initially at their fair values at the acquisition date. On an acquisition-by-acquisition basis, the group recognises any non-controlling interests in the acquiree either at fair value or at the non-controlling interest’s proportionate share of the acquiree’s net assets. The excess of the sum of the consideration transferred, the amount of any non-controlling interest in the acquiree and the acquisition-date fair value of any previously held equity interest in the acquiree over the fair value of the group’s share of the identifiable net assets acquired is recorded as goodwill. If this is less than the fair value of the net assets of the subsidiary acquired, in the case of a bargain purchase, the difference is recognised directly in the income statement below operating profit or loss. 2 ACCOUNTING POLICIES continued GROUP ACCOUNTING POLICIES continued 2.1 Consolidation continued (ii) Associates Associates are entities in which the group has significant influence, but not control, over operational and financial policies. This may be when there is a shareholding of between 20% and 50% of the voting rights or when significant influence can be otherwise demonstrated, for example where the group has the right of representation on the board of directors, or other governing body, of the entity. Investments in associates are accounted for by using the equity method of accounting, and are initially recognised at cost. The group’s investment in associates includes goodwill identified on acquisition. Cumulative post-acquisition movements are adjusted against the carrying amount of the investment. The group’s share of the associates’ post-acquisition profits or losses is recognised in the income statement, and its share of post acquisition movement in reserves is recognised in other reserves. When the group’s share of losses in an associate equals or exceeds its interest in the associate, the group does not recognise further losses, unless it has incurred obligations or made payments on behalf of the associate. The carrying value of an associate is reviewed on a regular basis and, if impairment in the carrying value has occurred, it is written off in the period in which such impairment is identified. Accounting policies of associates have been reviewed to ensure consistency with the policies adopted by the group. (iii) Joint arrangements Joint arrangements are arrangements of which two or more parties have joint control and are contractually bound. The joint arrangement can either be a joint operation or a joint venture. A joint operation is a joint arrangement whereby the parties that have joint control of the arrangement and have the right to the assets, and obligations for the liabilities, relating to the arrangement. These parties are called joint operators. A joint venture is a joint arrangement where the parties that have joint control of the arrangement have rights to the net assets of the arrangement. Those parties are called joint venturers. For interest in joint operations, the group includes its share of the joint operations' individual income and expenses, assets and liabilities and cash flows on a line-by-line basis with similar items in the group’s financial statements. Where an additional interest in a joint operation is acquired, the principles of IFRS 3 are applied to account for the transaction. The group recognises the portion of gains or losses on the sale of assets by the group to the joint operation that is attributable to the other joint operators. The group does not recognise its share of profits or losses from the joint operation that results from the purchase of assets by the group from the joint operation until it resells the assets to an independent party. However, if a loss on the transaction provides evidence of a reduction in the net realisable value of current assets or an impairment loss, the loss is recognised immediately. The group recognises its interest in a joint venture as an investment and accounts for it using the equity accounting method. (iv) Structured entities A structured entity is an entity that has been designed so that voting or similar rights are not the dominant factor in deciding who controls the entity, such as when any voting rights relate to administrative tasks only and the relevant activities are directed by means of contractual arrangements. The accounting treatment for a structured entity will fall into one of the aforementioned categories (i to iii) depending on whether the group has control over that structured entity. 2.2 Foreign currency translation (i) Functional and presentation currency Items included in the financial statements of each of the group’s entities are measured using the currency of the primary economic environment in which the entity operates (the functional currency). The consolidated financial statements are presented in South African Rand, which is the group’s presentation currency. References to “A$” refers to Australian currency, “R” to South African currency, “$” or “US$” to United States currency and “K” or “kina” to Papua New Guinean currency. (ii) Transactions and balances Foreign exchange gains and losses resulting from the settlement of foreign currency transactions and from the translation to year-end exchange rates of monetary assets and liabilities denominated in foreign currencies are recognised in the income statement. This includes the gains and losses on the translation of the US$-denominated facilities. Gains and losses recognised in the income statement are included in the determination of other operating expenses. 2 ACCOUNTING POLICIES continued GROUP ACCOUNTING POLICIES continued 2.2 Foreign currency translation continued (iii) Group companies The results and financial position of all group entities (none of which has the currency of a hyperinflationary economy) that have a functional currency different from the presentation currency are translated into the presentation currency as follows: • Assets and liabilities for each balance sheet presented are translated at the closing rate at the date of that balance sheet while equity items are translated at historic rates; • Income and expenses for each income statement are translated at average exchange rates (the rate on the date of the transaction is used if the average is not a reasonable rate for the translation of the transaction); • All resulting exchange differences are recognised as a separate component of other comprehensive income. On consolidation, exchange differences arising from the translation of the net investment in foreign operations, and of borrowings and other currency instruments designated as hedges of such investments, are taken to other comprehensive income. When a foreign operation is sold or control is otherwise lost, exchange differences that were recorded in other comprehensive income are recognised in profit or loss in the period of the disposal or change in control. Goodwill and fair value adjustments arising on the acquisition of a foreign operation are treated as assets and liabilities of the foreign entity and translated at the closing rate. 2.3 Derivatives and hedging activities Derivatives are initially recognised at fair value on the date a derivative contract is entered into and are subsequently remeasured to their fair value at the end of each reporting period. The accounting for subsequent changes in fair value depends on whether the derivative is designated as a hedging instrument, and if so, the nature of the item being hedged. The difference between the fair value of the derivative at initial recognition and expected forward transaction price is deferred and recognised as a day one gain or loss. The day one gain or loss is amortised over the derivative contract period and recognised in profit or loss in gains/losses on derivatives. The full fair value of a derivative is classified as a non-current asset or liability when the remaining maturity is more than 12 months; it is classified as a current asset or liability when the remaining maturity is less than 12 months . (i) Cash flow hedge The group designates certain derivatives as hedges of a particular risk associated with the cash flows of highly probable forecast transactions (cash flow hedges). At inception of the hedge relationship, the group documents the economic relationship between hedging instruments and hedged items including whether changes in the cash flows of the hedging instruments are expected to offset changes in the cash flows of hedged items. The group documents its risk management objective and strategy for undertaking its hedge transactions. The effective portion of changes in the fair value of derivatives that are designated and qualify as cash flow hedges is recognised in other comprehensive income and accumulated in reserves in equity. The gain or loss relating to the ineffective portion is recognised immediately in profit or loss within gains/losses on derivatives. Amounts accumulated in equity are reclassified to profit or loss in the periods when the forecast sale that is hedged takes place and affects profit or loss. The gain or loss relating to the effective portion of the Rand and US$ gold forward sales contracts is recognised in profit or loss within revenue. When a hedging instrument expires or is sold or terminated, or when a hedge no longer meets the criteria for hedge accounting, any cumulative gain or loss existing in equity at that time remains in equity and is recognised when the forecast transaction that was hedged is ultimately recognised in profit or loss. When a forecast transaction is no longer expected to occur, the cumulative gain or loss that was reported in equity is immediately reclassified to profit or loss. (ii) Derivatives not designated for hedge accounting purposes Certain derivative instruments do not qualify for hedge accounting. Changes in the fair value as well as gains and losses on expiry, disposal or termination of any derivative instrument that does not qualify for hedge accounting are recognised immediately in profit or loss and are included in gains/losses on derivatives. 2 ACCOUNTING POLICIES continued GROUP ACCOUNTING POLICIES continued 2.4 Exploration expenditure The group has elected to expense all exploration and evaluation expenditures until it is concluded that the project is technically feasible and commercially viable, and that future economic benefits are therefore probable. The information used to make that determination depends on the level of exploration as well as the degree of confidence in the ore body as set out below. Exploration and evaluation expenditure on greenfield sites, being those where the group does not have any mineral deposits which are already being mined or developed, is expensed as incurred until the technical and commercial viability of the project has been demonstrated usually through the completion of a final feasibility study. However, in certain instances, the technical and commercial viability of the deposit may be demonstrated at an earlier stage, for example where an extended feasibility study is conducted and the underlying feasibility study in respect of specific components of the mineral deposit has advanced to such a stage that significant commercially viable reserves has been established, and the other criteria for the recognition of an asset have been met. At this point the expenditure is capitalised as mine development cost to the extent that future economic benefits are expected. Exploration and evaluation expenditure on brownfield sites, being those adjacent to mineral deposits which are already being mined or developed, is expensed as incurred until the group is able to demonstrate that future economic benefits are probable through the completion of a feasibility study, after which the expenditure is capitalised as mine development cost to the extent that future economic benefits are expected. A ‘feasibility study’ consists of a comprehensive study of the viability of a mineral project that has advanced to a stage where the mining method has been established, and which, if an effective method of mineral processing has been determined, includes a financial analysis based on reasonable assumptions of technical, engineering, operating economic factors and the evaluation of other relevant factors. The feasibility study, when combined with existing knowledge of the mineral property that is adjacent to mineral deposits that are already being mined or developed, allows the group to conclude that the project is technically feasible and commercially viable. Exploration and evaluation expenditure relating to extensions of mineral deposits which are already being mined or developed, including expenditure on the definition of mineralisation of such mineral deposits, is capitalised as a mine development cost following the completion of an economic evaluation equivalent to a feasibility study. This economic evaluation is distinguished from a feasibility study in that some of the information that would normally be determined in a feasibility study is instead obtained from the existing mine or development. This information, when combined with existing knowledge of the mineral property already being mined or developed, allows the directors to conclude that the project is technically feasible and commercially viable. 2.5 Impairment of non-financial assets Assets that have an indefinite useful life are not subject to amortisation or depreciation and are tested annually for impairment or when there is an indication of impairment. Assets that are subject to amortisation are reviewed annually on 30 June for impairment or whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. An impairment loss is recognised in the income statement for the amount by which the asset’s carrying amount exceeds its recoverable amount. The recoverable amount is the higher of an asset’s fair value less costs to sell and value in use. For the purposes of assessing impairment, assets are grouped at the lowest levels for which there are separately identifiable cash flows (cash generating unit or CGU). Each operating shaft, along with allocated common assets such as plants and administrative offices, is considered to be a cash generating unit as each shaft is largely independent from the cash flows of other shafts and assets belonging to the group. Fair value less cost to sell is generally determined by using discounted estimated after-tax future cash flows. Future cash flows are estimated based on quantities of recoverable minerals, expected commodity prices (considering current and historical prices, price trends and related factors), production levels and cash costs of production, all based on life-of-mine (LoM) plans. Future cash flows are discounted to their present value using a post-tax discount rate that reflects current market assessments of the time value of money and risk specific to the asset. Refer to note 13 for detail. The term “recoverable minerals” refers to the estimated amount of gold that will be obtained from reserves and resources and all related exploration stage mineral interests (except for other mine-related exploration potential and greenfields exploration potential discussed separately below) after taking into account losses during ore processing and treatment. Estimates of recoverable minerals from such related exploration stage mineral interests will be risk adjusted based on management’s relative confidence in such materials. In estimating future cash flows, assets are grouped at the lowest level for which there are identifiable cash flows that are largely independent of cash flows from other asset groups. With the exception of other mine-related exploration potential and greenfields exploration potential, estimates of future undiscounted cash flows are included on an area of interest basis, which generally represents an individual operating mine, even if the mines are included in a larger mine complex. 2 ACCOUNTING POLICIES continued GROUP ACCOUNTING POLICIES continued 2.5 Impairment of non-financial assets continued In the case of mineral interests associated with other mine-related exploration potential and greenfields exploration potential, cash flows and fair values are individually evaluated based primarily on recent exploration results and recent transactions involving sales of similar properties, if any. Assumptions underlying future cash flow estimates are subject to significant risks and uncertainties. Impairment losses on goodwill are recognised immediately in the income statement and are not reversed. The impairment testing is performed annually on 30 June or when events or changes in circumstances indicate that it may be impaired. Non-financial assets other than goodwill that suffered an impairment are reviewed annually for possible reversal of the impairment at 30 June. Reversal of impairments is also considered when there is objective evidence to indicate that the asset is no longer impaired. Where an impairment subsequently reverses, the carrying amount of the asset or CGU is increased to the revised estimate of its recoverable amount, but not higher than the carrying value that would have been determined had no impairment been recognised in prior

Accounting Policies, Changes In Accounting Estimates And Errors [Abstract]
Critical Accounting Estimates and Judgements	CRITICAL ACCOUNTING ESTIMATES AND JUDGEMENTS The preparation of the financial statements in conformity with IFRS requires the group’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities as well as disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Refer to the specific notes below for further information on the key accounting estimates and assumptions applied. • Estimate of taxation – note 10 ; • Recognition of deferred tax asset – note 10 ; • Gold mineral reserves and resources – note 13 ; • Production start date – note 13 ; • Stripping activities – note 13 ; • Impairment of assets – note 13 ; • Depreciation of property plant and equipment – note 13 ; • Exploration and evaluation assets – note 13 ; • Impairment of goodwill – note 14 ; • Valuation of interest in associate – note 20 ; • Provision for stock obsolescence - note 22 ; • Estimate of exposure and liabilities with regard to rehabilitation costs – note 25 ; • Estimate of provision for silicosis settlement – note 26 ; • Estimate of employee benefit liabilities – note 27 ; • Leases - note 28 ; • Fair value of share-based payments – note 34 ; • Assessment of contingencies – note 36 ; and • Valuation of derivative financial instruments – note 37 . IMPACT ON CRITICAL ESTIMATES AND JUDGEMENTS The uncertainty of the impact of the COVID-19 pandemic on the global economy caused significant volatility in the markets, as discussed above. This impacted on certain assumptions and estimates as at 30 June 2020 that management used in calculations which are revised annually or assessed at each reporting date. Key assumptions for the calculation of the mining assets' recoverable amounts include commodity prices and exchange rates. The increase in the US$ gold price and the weakening of the Rand against the US$ affected the short- and medium-term views in the forecasts management received from various institutions in order to determine the assumptions for impairment testing. However, management determined its reserves using the long-term price of US $1 350 /oz or R630 000 /kg and prepared the life-of-mine plans for the 2021 financial year at this price. Refer to note 13 for further details on the assumptions used in the impairment test. 4 . COVID-19 IMPACT continued IMPACT ON CRITICAL ESTIMATES AND JUDGEMENTS continued The valuation of the derivatives was also impacted by the changes in the commodity prices and Rand/US$ exchange rate. Refer to notes 18 and 37 for details of the fair value movements at 30 June 2020. The changes in the interest rates impacted on discount rates that are based on risk-free rates. These include, but are not limited to, the provisions for environmental rehabilitation, silicosis settlement and post-retirement benefits, the determination of recoverable amounts for testing impairments of non-financial assets as well as in recoverability of financial assets. Where possible and deemed relevant, management used weighted averages over a period of time to determine the estimated rates. In all cases, the discount rate decreased, the quantum of the decrease depending on whether the rate was a short-, medium- or long-term rate.

COVID-19 Impact

COVID-19 [Abstract]
COVID-19 Impact	COVID-19 IMPACT SOUTH AFRICA On 27 March 2020, South Africa was placed under national lockdown, to curb the spread of the Coronavirus (COVID-19) and allow the country time in which to prepare for the demands the pandemic would have on its health care system. All of Harmony’s underground operations were placed on care and maintenance, with the surface operations permitted to continue working at close to full capacity. Harmony rolled out a risk assessment-based COVID-19 prevention strategy across all of its operations before the lockdown was announced. The objective of the risk assessment was to identify, evaluate and rank the hazards associated with any exposures to COVID-19 and potential infections. It allowed the company to reduce or eliminate the probability of an employee contracting COVID-19 and to limit the severity should an employee be infected. 4 . COVID-19 IMPACT continued SOUTH AFRICA continued Harmony has been managing COVID-19 related health risks through the following measures: • a risk awareness campaign through various communication channels; • identification of high-risk employees; • the compulsory use of preventative personal protection equipment, which includes face masks, in designated areas in the workplace, increased hand washing and social distancing; • the sanitation of common areas and surfaces on a regular basis during the day; • placement of hand sanitisers and additional hand washing stations at the surface areas of the mines; • group meetings are avoided and where possible, meetings are conducted virtually in the form of tele-conferences or video-conferences; • implementation of work from home practices for central services and corporate office; • implementation of a comprehensive employee wellness monitoring and support programme, which includes a COVID-19 hotline . On 1 May 2020, South African underground operations were granted concessions to start producing at a maximum capacity of 50% and as of 1 June 2020, operational restrictions were lifted further to allow the mining industry to operate at 100% of its labour capacity. Harmony’s COVID-19 Standard Operating Procedure (SOP) was adopted and rolled out, ensuring a safe return to work for each of its employees. Harmony’s SOP was informed by guidelines provided by the Department of Mineral Resources and Energy, the National Council for Infectious Diseases and the World Health Organisation. The SOP included the transport of South African employees from remote labour-sending areas back to the company's mines. All requisite staffing, facilities and equipment were put in place to ensure rigorous screening as employees return to work and when at work, as well as isolate or quarantine employees infected by or exposed to COVID-19, with subsequent testing and treatment. Return to work has progressed smoothly albeit slowly, with the return of foreign nationals to South Africa taking longer than anticipated. PAPUA NEW GUINEA Harmony’s Hidden Valley mine in Papua New Guinea has continued to operate at 100% of its labour capacity during the COVID-19 State of Emergency declared in that country. The delivery of essential supplies to the mine has continued, with strict isolation control measures in place. All non-essential staff has been removed from site and certain activities and expenditures have been curtailed to focus on safe, profitable operations during the pandemic. Protocols were adopted to allow the safe movement of personnel to and from site during this period. FINANCIAL RISK MANAGEMENT The effects of COVID-19 and other macro developments have increased financial risks such as exchange rate, interest rate and commodity price volatility, while also impacting on liquidity and credit risk. Management has put various measures in place to mitigate and/or manage the risks and continues to monitor the situation closely. Refer to note 37 for additional detail. Balance sheet protection and liquidity measures The company committed to several measures to protect its balance sheet in the face of the global pandemic. These included cash preservation, the suspension of exploration and major capital projects and declaration of force majeure on select supplier agreements. Specific measures aimed at ensuring liquidity were undertaken, such as restructuring a portion of the derivatives maturing during April and May 2020 into the first three quarters of the new financial year, as well as drawing down on the Rand and US Dollar facilities. During June 2020, the company's lenders agreed to relax certain requirements for compliance with debt covenants until December 2020. Refer to note 30 for disclosures on debt covenants. Market impact Exchange rates Due to the impact of the COVID-19 pandemic, the Rand has weakened significantly from the beginning of the 2020 calendar year, which was at levels of around R 14.00 /US$1, to its weakest level at the beginning of April 2020 of R 19.05 . The Rand strengthened through May and June and the Rand closed at R 17.32 on 30 June 2020. The Rand started weakening against the Australian dollar in April 2020 and closed at R 11.96 /A$1 on 30 June 2020, a 21% decrease in value. These movements in the currencies expose the group's operations to foreign currency gains and losses on foreign-denominated receivables and liabilities, including derivatives, and also impact the group’s translation of its international operating results and net assets into its Rand presentation currency, which resulted in a foreign exchange translation movement of R1.2 billion in other comprehensive income. The most significant impact was on the increase in the Rand gold price Harmony received on its gold sales, of which R2.3 billion of the increase in revenue can be attributed to the weakening of the Rand. This was calculated by multiplying actual kilograms sold in the 2020 financial year by the variance in the average exchange rates year on year and 2019's average US$ gold price received. 4 . COVID-19 IMPACT continued FINANCIAL RISK MANAGEMENT continued Market impact continued Commodity prices Gold prices have rallied to an all-time high following the global economic fallout of COVID-19 and ongoing geopolitical uncertainty supporting its safe haven status with investors. The price of gold in US$ terms increased significantly over the period, closing at US$1 781/oz on 30 June 2020. This is a 26% increase from the closing price of US$1 410 /oz on 30 June 2019. The average spot gold price received (that is, excluding the impact of hedging gains or losses) for the 2020 financial year was 21% higher at US$1 529 /oz than in 2019 ( US$1 263 /oz), contributing approximately R5.2 billion to the increase in revenue year on year. This was calculated by multiplying actual kilograms sold in the 2020 financial year by the variance in the average US$ gold price year on year and 2020's average R/US$ exchange rate. Interest rates The US Federal Reserve lowered interest rates several times during the year, the majority unrelated to the COVID-19 pandemic. The rate cuts of 25 basis points were made on each of the following dates, 31 July 2019, 18 September 2019, 30 October 2019 and 3 March 2020. At an unscheduled meeting on 15 March 2020, an additional cut of 100 basis points was announced, reducing the rate to a range of between 0% and 0.25% as a benchmark for most interest rates. The South African Reserve Bank (SARB) announced similar decreases in the repo rate during the year. The adjustment in the repo rate then affects the prime lending rate at which commercial banks lend money. The repo rate was cut by 25 basis points at the July 2019 and January 2020 SARB meetings respectively. Following the interest rate cut by the Federal Reserve in March 2020, the SARB also announced a 100 basis point cut. At a special unscheduled meeting in April 2020, the SARB cut the rate by a further 100 basis points. During the scheduled May 2020 meeting, another 50 basis point cut was decided on, bringing the prime lending rate to 7.25% and the total cuts for the 2020 financial year to 300 basis points. These decreases have had a favourable impact on the cost of debt, as the debt facilities are linked to variable rates, US LIBOR and JIBAR specifically. However, the finance cost on the US-denominated debt is impacted by the movement in the Rand/US$ exchange rate. IMPACT ON PRODUCTION Management has worked with suppliers to ensure that there are minimal disruptions to the supply chain, which would otherwise impact negatively on the ability to continue with production. Stock levels for critical production and safety items were increased to cover an additional four weeks. In South Africa, some issues have been experienced where raw materials are imported as well as where certain manufacturers have been affected by absenteeism due to COVID-19. Supplies to the operations in Papua New Guinea have not been affected as management has been able to find alternative sources where necessary. CONTRIBUTING TO COMMUNITIES Harmony’s response to COVID-19 demonstrated once again its ability to respond quickly to challenging issues; in this case, protecting the lives and livelihoods of its employees, ensuring the continued viability of the business, and contributing to the wellbeing of surrounding communities and countries in which the group operates.Notwithstanding the challenges the group faced during the pandemic, Harmony provided emergency help and support in various forms to families most in need in host and neighbouring communities, both in South Africa and Papua New Guinea. TAXATION In response to challenges faced by companies during the COVID-19 pandemic, governments have implemented various stimulus packages to provide some relief to companies. In South Africa, various taxes have been delayed, such as carbon tax, where the first payment has been postponed to October 2020. In addition, a tax holiday of the skills development levy was introduced. IMPACT ON CRITICAL ESTIMATES AND JUDGEMENTS The uncertainty of the impact of the COVID-19 pandemic on the global economy caused significant volatility in the markets, as discussed above. This impacted on certain assumptions and estimates as at 30 June 2020 that management used in calculations which are revised annually or assessed at each reporting date. Key assumptions for the calculation of the mining assets' recoverable amounts include commodity prices and exchange rates. The increase in the US$ gold price and the weakening of the Rand against the US$ affected the short- and medium-term views in the forecasts management received from various institutions in order to determine the assumptions for impairment testing. However, management determined its reserves using the long-term price of US $1 350 /oz or R630 000 /kg and prepared the life-of-mine plans for the 2021 financial year at this price. Refer to note 13 for further details on the assumptions used in the impairment test. 4 . COVID-19 IMPACT continued IMPACT ON CRITICAL ESTIMATES AND JUDGEMENTS continued The valuation of the derivatives was also impacted by the changes in the commodity prices and Rand/US$ exchange rate. Refer to notes 18 and 37 for details of the fair value movements at 30 June 2020. The changes in the interest rates impacted on discount rates that are based on risk-free rates. These include, but are not limited to, the provisions for environmental rehabilitation, silicosis settlement and post-retirement benefits, the determination of recoverable amounts for testing impairments of non-financial assets as well as in recoverability of financial assets. Where possible and deemed relevant, management used weighted averages over a period of time to determine the estimated rates. In all cases, the discount rate decreased, the quantum of the decrease depending on whether the rate was a short-, medium- or long-term rate.

Revenue [abstract]
Revenue	REVENUE ACCOUNTING POLICY Revenue from metal sales include the sale of gold, silver and uranium. Revenue from metal sales is recognised when the group satisfies its performance obligations under its contract with the customer, by transferring such metals to the customer's control. Transfer of control is generally determined to be when the risk and title to the metals passes to the customer. Revenue is measured based on the consideration specified in the contract with the customer and is driven by the quoted market prices of the metals. The effective portion of gains or losses on the derivatives designated as cash flow hedging items (forecast sales transactions) are recognised in revenue when the forecast sales transactions occur. See the accounting policy for derivatives and hedging activities in note 2 .

Refer to note 18 for further information. 4 A geographical analysis of revenue is provided in the segment report in note 39 . The points of transfer of control are as follows: • Gold: South Africa Gold is delivered and certificate of sale is issued. • Gold and silver: Hidden Valley For sales up to 13 February 2019: metal is delivered and metal account credited by the customer. Sales from 14 February 2019 onwards: metal is collected from Hidden Valley and a confirmation of collection is sent to and accepted by the customer. • Uranium Confirmation of transfer is issued. The increase in gold and silver revenue for 2020 is mainly due to the higher commodity prices. The increase in gold revenue is offset by the decrease in production of 15% from 44 734 kg in the 2019 to 37 863 kg in the current year. Silver produced increased by 11% to 97 332 kg from 87 325 kg in the prior year. The decrease in uranium revenue is due to lower sales volumes as a result of the South African nationwide lockdown that took place due to COVID-19. 5 REVENUE continued Below are the average commodity prices received for the financial years: 2020 2019 2018 Gold 1 – US$ per ounce (US$/oz) 1 461 1 287 1 380 – Rand per kilogram (R/kg) 735 569 586 653 570 709 Silver – US$ per ounce (US$/oz) 16.85 15.00 16.88 – Rand per kilogram (R/kg) 8 485 6 837 6 974 Uranium – US$ per pound (US$/lb) 25.34 26.23 23.71 – Rand per kilogram (R/kg) 875 820 672 1 The gold price includes the realised effective portion of the hedge-accounted gold derivatives.

Employee termination costs are included, except for employee termination costs associated with major restructuring and shaft closures, which are separately disclosed. Production costs increased during the 2020 year mainly in line with expectations, with the South African national lockdown from the end of March 2020 due to COVID-19 impacting on production volumes while the cost base remained mostly unchanged. Contributing to the increase year on year is a decrease of R557 million in the capitalised stripping credit related to the Hidden Valley operation. 6 COST OF SALES continued (a) Production costs continued Production costs, analysed by nature, consist of the following: SA Rand Figures in million 2020 2019 2018 Labour costs, including contractors 13 004 12 715 9 750 Consumables 5 441 5 532 3 418 Water and electricity 3 664 3 398 2 551 Insurance 154 126 86 Transportation 377 354 121 Change in inventory (70 ) (166 ) (211 ) Capitalisation of mine development costs (1 485 ) (1 880 ) (1 552 ) Stripping activities (675 ) (1 197 ) (167 ) Royalty expense 327 193 121 Other 1 311 1 249 967 Total production costs 22 048 20 324 15 084 (b) Lower production volumes during the 2020 year, partially due to the closure of underground mines following the announcement of the South African national lockdown due to COVID-19, impacted on the depreciation recorded and contributed to the decrease year on year. The completion of the mining of Stage 5 at Hidden Valley during the December 2019 quarter also contributed to the decrease. The impairments recognised on certain operations in South Africa during the 2019 year significantly impacted on the base which depreciation is calculated on and the lower carrying values contributed to the lower total compared to the comparative period. Amortisation and depreciation of assets other than mining assets includes the amortisation of intangible assets. (c) For the assumptions used to calculate the rehabilitation costs, refer to note 25 . This expense includes the change in estimate for the rehabilitation provision where an asset no longer exists as well as costs related to the rehabilitation process. For 2020 , R47 million ( 2019 : R86 million ) ( 2018 : R94 million ) was spent on rehabilitation in South Africa. Refer to note 25 . (d) The employment termination and restructuring expenditure for 2020, 2019 and 2018 relates to the voluntary severance program in place to reduce labour costs. (e) Refer to note 34 for details on the share-based payment schemes implemented by the group. (f) Management performed an assessment for impairment triggers as well as indications of reversal of previously recorded impairment losses at 30 June 2020. Due to the uncertainty of the impact of the COVID-19 pandemic and the South African national lockdown would have on the South African underground operations, as well as the increase in the short-term gold price, the recoverable amounts for these cash-generating units (CGUs) were calculated. Based on the impairment tests performed, no impairments were recorded for the 2020 year. Where CGUs had previously been impaired, management considered whether the impairment loss (or the contributors to the previously recognised impairment loss) no longer exists or might have decreased. Management considered general and specific factors for each CGU and concluded that although overall the gold price had improved from the time that the impairment losses had been recognised, the specific circumstances that led to the original impairments had not reversed. Management also considered the level of uncertainty of the impact of COVID-19 on production and therefore on the cash flows. Due to the volatility embedded in the potential upside driven by the higher gold prices in the short to medium term, coupled with the fact that the factors resulting in the previously recognised impairment losses had not reversed, management resolved it to be appropriate for no reversal of previously recognised impairment losses to be recorded for the period under review. Refer to note 13 for further information. 6 COST OF SALES continued (f) Impairment continued The impairment of assets consists of the following: SA Rand Figures in million 2020 2019 2018 Tshepong Operations — 2 254 988 Kusasalethu — 690 579 Target 1 — 312 699 Target 3 — 318 — Joel — 198 160 Other mining assets — 120 319 Bambanani — 6 — Doornkop — — 317 Unisel — — 487 Masimong — — 329 Target North — — 1 458 Total impairment of assets — 3 898 5 336 There was no reversal of impairment for the 2020, 2019 or 2018 financial years. The recoverable amounts for these assets have been determined on a fair value less costs to sell basis using the assumptions per note 13 in discounted cash flow models and attributable resource values. These are fair value measurements classified as level 3. The recoverable amounts of the CGUs where impairments were recognised as at 30 June 2019 are as follows: SA Rand Recoverable amount Figures in million Life-of-Mine plan Resource base Total Tshepong Operations The impairment was due to the increased costs to exploit the resource base as well as a lower expected recovered grade. The decrease in the recovery grade is as a result of the change in the dilution factors applied to the outside life of mine resources. 3 811 2 055 5 866 Kusasalethu The decrease in grade and increased estimated costs in the resource base resulted in a lower recoverable amount. The decrease in the recovery grade is as a result of the change in the dilution factors applied to the outside life of mine resources. 1 297 — 1 297 Target 1 The recoverable amount decreased as a result of increased costs and decrease in grade in the resource base together with the estimated impact of carbon tax. The increase in discount rate due to increased risk factors also negatively impacted on the recoverable amount. 467 609 1 076 Target 3 The operation remained under care and maintenance.

Finance Costs	FINANCE COSTS ACCOUNTING POLICY Borrowing costs are capitalised to the extent that they are directly attributable to the acquisition and construction of qualifying assets. Qualifying assets are assets that take a substantial time to get ready for their intended use. These costs are capitalised until the asset moves into the production phase. Other borrowing costs are expensed. The foreign exchange translation loss is included in the borrowing cost calculation to the extent that it is considered to be a part of interest.

Taxation

Income Taxes [Abstract]
Taxation	TAXATION ACCOUNTING POLICY Taxation is made up of current and deferred taxation. The current income tax charge is calculated on the basis of the tax laws enacted or substantively enacted at the balance sheet date in the countries where the group operates and generates taxable income. Management periodically evaluates positions taken in tax returns with respect to situations in which applicable tax regulations are subject to interpretation and establishes provisions where appropriate on the basis of amounts expected to be paid to the tax authorities. Deferred taxation is recognised on temporary differences existing at each reporting date between the tax base of all assets and liabilities and their carrying amounts. Substantively enacted tax rates are used to determine future anticipated effective tax rates which in turn are used in the determination of deferred taxation, except to the extent that deferred tax arises from the initial recognition of an asset or liability in a transaction that is not a business combination and does not affect the accounting or taxable profit or loss at the time of the transaction. Deferred tax is charged to profit or loss, except where the tax relates to items recognised in other comprehensive income or directly in equity in which case the tax is also recognised in other comprehensive income or directly in equity. The effect on deferred tax of any changes in tax rates is recognised in the income statement, except to the extent that it relates to items previously charged or credited directly to equity. The principal temporary differences arise from amortisation and depreciation on property, plant and equipment, provisions, unutilised tax losses, unutilised capital allowances carried forward and unrealised gains and losses on the gold forward sale contracts. Deferred tax assets relating to the carry forward of unutilised tax losses and unutilised capital allowances are recognised to the extent that it is probable that future taxable profit will be available against which the unutilised tax losses and unutilised capital allowances can be utilised. The recoverability of these assets is reviewed at each reporting date and adjusted if recovery is no longer probable. Deferred income tax is provided on temporary differences arising from investments in subsidiaries, joint ventures and associates, except where the timing of the reversal of the temporary difference is controlled by the group and it is probable that the temporary difference will not reverse in the foreseeable future. Deferred income 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 income tax assets and liabilities relate to income taxes levied by the same taxation authority on either the taxable entity or different taxable entities where there is an intention to settle the balances on a net basis. CRITICAL ACCOUNTING ESTIMATES AND JUDGEMENTS The group is subject to income tax in several jurisdictions. Significant judgement is required in determining the worldwide provision for income taxes due to the complexity of legislation. There are many transactions and calculations for which the ultimate tax determination is uncertain during the ordinary course of business. Where the final tax outcome is different from the amounts that were initially recorded, such differences will impact the income tax and deferred tax provisions in the period in which such determination is made. Deferred tax assets and liabilities are measured at the tax rates that are expected to apply to the period when the asset is realised or the liability is settled. When different tax rates apply to different levels of taxable income, deferred tax assets and liabilities are measured using the average tax rates that are expected to apply to the taxable profit (tax loss) of the periods in which the temporary differences are expected to reverse. At the group’s South African operations, such average tax rates are directly impacted by the profitability of the relevant mine. The deferred tax rate is therefore based on the current estimate of future profitability of an operation when temporary differences will reverse, based on tax rates and tax laws that have been enacted at the balance sheet date. The future profitability of each mine, in turn, is determined by reference to the life-of-mine (LoM) plan for that operation. The LoM plan is influenced by factors as disclosed in note 13 , which may differ from one year to the next and normally result in the deferred tax rate changing from one year to the next. Management has to exercise judgement with regard to deferred tax assets. Where the possibility exists that no future taxable income may flow against which these assets can be offset, the deferred tax assets are not recognised. 10 TAXATION continued The taxation (expense)/credit for the year is as follows: SA Rand Figures in million 2020 2019 2018 SA taxation Mining tax (a) (56 ) (19 ) (42 ) - current year (61 ) (14 ) (42 ) - prior year 5 (5 ) — Non-mining tax (b) (2 ) (124 ) (163 ) - current year (2 ) (121 ) (163 ) - prior year — (3 ) — Deferred tax (c) (197 ) 282 439 - current year (197 ) 282 439 Total taxation (expense)/credit (255 ) 139 234 (a) Mining tax on gold mining taxable income in South Africa is determined according to a formula, based on the taxable income from mining operations. 5% of total revenue is exempt from taxation while the remainder is taxable at a higher rate ( 34% ) than non-mining income ( 28% ) as a result of applying the gold mining formula. Mining and non-mining income of Australian entities and PNG operation are taxed at a standard rate of 30% . All qualifying mining capital expenditure is deducted from taxable mining income to the extent that it does not result in an assessed loss. Accounting depreciation is eliminated when calculating the South African mining tax income. Excess capital expenditure is carried forward as unredeemed capital to be claimed from future mining taxable income. The group has several tax paying entities in South Africa. In terms of the mining ring-fencing application, each ring-fenced mine is treated separately and deductions can normally only be utilised against mining income generated from the relevant ring-fenced mine. (b) Non-mining taxable income of mining companies and the taxable income for non-mining companies are taxed at the statutory corporate rate of 28% .The expense for the 2019 and 2018 years relates to non-mining tax arising from derivative gains (realised and unrealised) recognised on the foreign currency derivatives as well as the realised gains on the commodity forward sale contracts. During 2020, the losses on the derivative contracts resulted in non-mining tax losses. See discussion on deferred tax below. Refer to note 18 for details on the group's derivative gains and losses recorded. (c) The deferred tax rate used to calculate deferred tax is based on the current estimate of future profitability when temporary differences will reverse based on tax rates and tax laws that have been enacted at the balance sheet date. Depending on the profitability of the operations, the deferred tax rate can consequently be significantly different from year to year. Following the completion of the annual life-of-mine plans, management revised the weighted average deferred tax rates for all the South African operations. The higher short-term gold price assumption used resulted in an increase in the estimated profitability and consequently higher rates than in the prior year. Refer to note 13 for the assumptions used. These changes, together with changes in the temporary differences, had the following impacts: • The change in rates on temporary differences at the individual company level, other than hedge accounted derivatives, resulted in an increase in the deferred tax expense and liability to the amount of R493 million . • Unwinding of temporary differences related to unredeemed capital expenditure balance resulted in an increase of R298 million in the deferred tax expense. • The weakening of the Rand against the US$ and the increase in the commodity prices negatively impacted on the valuation of the derivative financial instruments. Refer to notes 18 and 37 for detail. The temporary differences related to the Rand gold derivatives changed from taxable temporary differences (ie resulting in a deferred tax liability) to deductible temporary differences (resulting in a deferred tax asset). Management assessed the rates at which the temporary differences are expected to reverse and as the expected non-mining losses can be set off against the mining profits, the rates have been revised from the non-mining tax rate of 28% to the weighted average deferred tax rate. This accounts for R510 million of the deferred tax credit directly charged to other comprehensive income. 10 TAXATION continued (c) Deferred tax continued • The net deferred tax positions for each of the group's entities are assessed separately. Two companies have net deferred tax asset positions and therefore recoverability of these assets was considered. The position at 30 June 2020 was as follows: SA Rand Figures in million Harmony Company Randfontein Estates Deductible/(taxable) temporary differences 1 079 (155) Tax losses 574 534 Total 1 653 379 Deferred tax rate 29.8 % 10.1 % Deferred tax asset 492 39 At 30 June 2020, management considered whether the unrecognised deferred tax asset (DTA) related to the Harmony company should be recognised, partially or in full. A portion of the DTA relates to a tax loss of R574 million , which primarily arose due to the foreign exchange translation losses and losses on derivatives recorded in 2020. The company's operations include the Central Plant Reclamation (CPR), a tailings retreatment facility. As a low cost producer, its profit margins are highly sensitive to fluctuations in the gold price. In addition, the higher short-term gold price also significantly benefits Masimong's profitability, which following the revision of its life-of-mine at 30 June 2020 has two years remaining of its life. Due to the significant expected increase in the short-term Rand gold price used in the estimation of future taxable profits for the mining operations owned by the Harmony company, it is considered probable that sufficient future taxable profits will be available against which the aforementioned tax loss and the current deductible temporary differences existing at the reporting date can be utilised. Consequently, a deferred tax asset of R492 million has been recognised, consisting of R171 million relating to the tax loss and R321 million relating to deductible temporary differences. Management believes there will be sufficient future taxable income from the operations owned by Randfontein Estates Limited and therefore the entire balance of R39 million was recognised at 30 June 2020. 10 TAXATION continued INCOME AND MINING TAX RATES The tax rate remains unchanged for the 2018 , 2019 and 2020 years. Major items causing the group's income tax provision to differ from the South African mining statutory tax rate of 34% were: SA Rand Figures in million 2020 2019 2018 Tax on net loss at the mining statutory tax rate 202 934 1 600 Non-allowable deductions (221 ) (241 ) (513 ) Share-based payments (62 ) (70 ) (104 ) Impairment of assets — (2 ) (219 ) Loan-related costs (19 ) (18 ) (24 ) Exploration expenditure (55 ) (36 ) (74 ) Finance costs (76 ) (68 ) (54 ) Other (9 ) (47 ) (38 ) Movement in temporary differences related to property, plant and equipment (355 ) (1 388 ) (1 248 ) Movements in temporary differences related to other assets and liabilities (452 ) 98 55 Difference between effective mining tax rate and statutory mining rate on mining income 10 (175 ) (550 ) Difference between non-mining tax rate and statutory mining rate on non-mining income — 19 35 Effect on temporary differences due to changes in effective tax rates 1 (469 ) 83 675 Prior year adjustment 5 (8 ) — Capital allowances 2 766 684 604 Deferred tax asset not recognised 3 34 133 (424 ) Deferred tax asset previously not recognised now recorded 4 225 — — Income and mining taxation (255 ) 139 234 Effective income and mining tax rate (%) (43 ) 5 5 1 This mainly relates to movements in the deferred tax rate related to Harmony ( 25.7% to 29.8% ) ( 2019 : 10.5% to 25.7% ) ( 2018 : 19.4% to 10.5% ), Freegold ( 8.1% to 11.4% ) ( 2019 : 8.7% to 8.1% ) ( 2018 : 12.5% to 8.7% ), Randfontein Estates Limited (Randfontein) ( 4.5% to 10.1% ) ( 2019 : 1.8% to 4.5% ) ( 2018 : 3.8% to 1.8% ) and Moab ( 4.7% to 17.3% ) ( 2019 : 9.1% to 4.7% ) ( 2018 : 9.1% ). 2 This relates to the additional capital allowance that may be deducted from taxable income from mining operations in South Africa. A significant portion relates to Avgold Limited (Avgold) which has a 0% effective tax rate. 3 This relates to tax losses and deductible temporary differences for which future taxable profits are uncertain and are not considered probable. 4 Harmony company has sufficient future profits as well as taxable temporary differences which the deductible temporary differences can be reversed against. Therefore the deferred tax asset not recognised in the 2019 year has been recognised. 10 TAXATION continued DEFERRED TAX The analysis of deferred tax assets and liabilities is as follows: SA Rand Figures in million 2020 2019 Deferred tax assets (1 803 ) (550 ) Deferred tax asset to be recovered after more than 12 months (1 091 ) (49 ) Deferred tax asset to be recovered within 12 months (712 ) (501 ) Deferred tax liabilities 2 268 1 237 Deferred tax liability to be recovered after more than 12 months 2 034 1 125 Deferred tax liability to be recovered within 12 months 234 112 Net deferred tax liability 465 687 Deferred tax liabilities and assets on the balance sheet as of 30 June 2020 and 30 June 2019 relate to the following: SA Rand Figures in million 2020 2019 Gross deferred tax liabilities 2 268 1 237 Amortisation and depreciation 2 211 1 229 Other 57 8 Gross deferred tax assets (1 803 ) (550 ) Unredeemed capital expenditure 1 (4 923 ) (4 044 ) Provisions, including non-current provisions (1 156 ) (844 ) Derivative financial instruments (505 ) (88 ) Tax losses 2 (1 718 ) (1 209 ) Deferred tax asset not recognised 3 6 499 5 635 Net deferred tax liability 465 687 1 Unredeemed capital expenditure mainly consists of Hidden Valley R4 555 million (2019: R3 745 million ). 2 The majority of the amount relates to Hidden Valley's tax losses of R1 327 million (2019: R1 066 million ). 3 The majority of the deferred tax asset not recognised of R6 499 million relates to Harmony's PNG operations ( 2019 : R5 293 million ). Movement in the net deferred tax liability recognised in the balance sheet is as follows: SA Rand Figures in million 2020 2019 Balance at beginning of year 687 1 145 Expense/(credit) per income statement 197 (282 ) Tax directly charged to other comprehensive income (419 ) (177 ) Balance at end of year 465 687 Deferred tax asset per balance sheet (531 ) (1 ) Deferred tax liability per balance sheet 996 688 10 TAXATION continued DEFERRED TAX continued SA Rand Figures in million 2020 2019 As at 30 June, the group had the following potential future tax deductions: Unredeemed capital expenditure available for utilisation against future mining taxable income 1 43 395 39 725 Tax losses carried forward utilisable against mining taxable income 2 7 356 5 494 Capital Gains Tax (CGT) losses available to be utilised against future CGT gains 4 570 571 As at 30 June, the group has not recognised the following deferred tax asset amounts relating to the above: 14 618 12 935 The unrecognised temporary differences are: Unredeemed capital expenditure 3 40 330 35 038 Tax losses 2 5 156 5 109 CGT losses 4 570 571 1 Includes Avgold R21 483 million ( 2019 : R19 086 million ), Randfontein R2 261 million ( 2019 : R2 134 million ), Moab Khotsong R625 million ( 2019 : R1 755 million ) and Hidden Valley R18 847 million ( 2019 : R16 333 million ). These have an unlimited carry-forward period. 2 Relates mainly to Hidden Valley and the PNG exploration operations. These have an unlimited carry-forward period. 3 Relates to Avgold and Hidden Valley. 4 The CGT losses relate to the gross CGT losses available to be utilised against future CGT gains.

Earnings/(Loss) Per Share	EARNINGS/(LOSS) PER SHARE BASIC EARNINGS/(LOSS) PER SHARE Basic earnings/(loss) per share is calculated by dividing the net income attributable to shareholders by the weighted number of ordinary shares in issue during the year. 2020 2019 2018 Ordinary shares in issue ('000) 603 143 539 841 500 252 Adjustment for weighted number of ordinary shares in issue ('000) (61 306 ) (12 974 ) (54 304 ) Weighted number of ordinary shares in issue ('000) 541 837 526 867 445 948 Treasury shares ('000) (6 501 ) (3 058 ) (52 ) Basic weighted average number of ordinary shares in issue ('000) 535 336 523 809 445 896 SA Rand 2020 2019 2018 Total net loss attributable to shareholders (million) (878 ) (2 607 ) (4 473 ) Total basic loss per share (cents) (164 ) (498 ) (1 003 ) DILUTED EARNINGS/(LOSS) PER SHARE For diluted earnings/(loss) per share, the weighted average number of ordinary shares in issue is adjusted to assume conversion of all potential dilutive ordinary shares as a result of share options granted to employees under the share option schemes in issue. A calculation is performed to determine the number of shares that could have been acquired at fair value, determined as the average annual market share price of the company's shares, based on the monetary value of the subscription rights attached to the outstanding share options. The number of shares calculated as above is compared with the number of shares that would have been issued assuming the exercise of the share options. 11 EARNINGS/(LOSS) PER SHARE continued DILUTED EARNINGS/(LOSS) PER SHARE continued 2020 2019 2018 Weighted average number of ordinary shares in issue ('000) 535 336 523 809 445 896 Potential ordinary shares 1 ('000) 11 858 9 537 19 423 Weighted average number of ordinary shares for diluted earnings per share 1 ('000) 547 194 533 346 465 319 SA Rand 2020 2019 2018 Total diluted loss per share (cents) 2 (166 ) (500 ) (1 004 ) 1 Due to the net loss attributable to shareholders, the inclusion of the share options as potential ordinary shares had an anti-dilutive effect on the loss. The issue price and the exercise price of share options issued to employees include the fair value of any service to be supplied to the entity in the future under the share option or other share-based payment arrangement. 2 The dilution is as a result of the potential reduction in earnings attributable to equity holders of the parent company as a result of the exercise of the Tswelopele Beneficiation Operation (TBO) option. TBO contributed a profit for the six months ended 31 December 2019 and therefore the reduction in earnings attributable to Harmony would increase the loss and loss per share. Following the vesting of the option (refer to note 34 ), there has been no further impact. DIVIDENDS ACCOUNTING POLICY Dividends declared are recognised in the period in which they are approved by the board of directors. Dividends are payable in South African Rand. Cash flows from dividends paid are classified under financing activities in the cash flow statement. • On 17 August 2017, the board declared a final dividend of 35 cents for the year ended 30 June 2017. R154 million million was paid on 16 October 2017. No dividends were paid on ordinary shares by Harmony during the 2020 and 2019 financial year. The payment in 2020 relates to the non-controlling interest in Tswelopele Beneficiation Operation. Refer to note 34 . • Harmony declares an annual preference share dividend to the Harmony Gold Community Trust (the Trust). On 30 July 2019, Harmony declared a preference dividend of R9 million to the Trust which was paid on 2 September 2019. As the Trust is consolidated by Harmony, the dividend is eliminated on consolidation. SA Rand 2020 2019 2018 Dividend declared (millions) — — 154 Dividend per share (cents) — — 35

Acquisitions and Business Combinations	ACQUISITIONS AND BUSINESS COMBINATIONS ACQUISITION OF ANGLOGOLD ASHANTI'S REMAINING SOUTH AFRICAN OPERATIONS TRANSACTION On 12 February 2020, Harmony announced that it has reached an agreement with AngloGold Ashanti Limited (AGA) to purchase AGA's remaining South African producing assets and related liabilities. The transaction includes the following assets and liabilities: • The Mponeng mine and its associated assets and liabilities; • The Tau Tona and Savuka mines and associated rock-dump and tailings storage facility reclamation sites, mine rehabilitation and closure activities located in the West Wits region and their associated assets and liabilities; • First Uranium (Pty) Limited which owns Mine Waste Solutions (Pty) Limited and Chemwes (Pty) Limited as well as associated tailings assets and liabilities (the FUSA Group); • Covalent Water Company (Pty) Limited (CWC), AngloGold Security Services (Pty) Limited and Masakhisane Investments (Pty) Limited; and • Certain rock-dump reclamation, mine rehabilitation and closure activities located in the Vaal River region and their associated assets and liabilities (the VR Remaining assets). 12 . ACQUISITIONS AND BUSINESS COMBINATIONS continued TRANSACTION continued Consideration for the transaction is a cash payment of US$200 million , due on the closing date, and a contingent consideration subject to the following criteria: • US$260 per ounce payable on all underground production from the Mponeng, Savuka and Tau Tona mines in excess of 250 000 ounces per year for six years commencing 1 January 2021; and • US$20 per ounce payable on underground production from the Mponeng, Savuka and Tau Tona mines sourced from levels developed in the future below the current infrastructure. At 30 June 2020, the closing of the transaction was still subject to certain conditions precedent. Refer to note 38 . FUNDING OF ACQUISITION CONSIDERATION THROUGH DEBT AND SHARES Harmony concluded a bridge loan to fund the acquisition consideration. Refer to note 30 and note 38 for further detail. As part of the funding strategy, Harmony approached its shareholders for authorisation to issue shares up to US$200 million to fund the acquisition consideration through: • A general authority to issue ordinary shares for cash, subject to the restrictions set out in the JSE Listings Requirements including that only public shareholders may participate; • A vendor consideration placement as set out in the JSE Listings Requirements, which would enable non-public shareholders to participate subject to certain conditions; and • Or a combination of the above. An Extraordinary General Meeting was held on 11 June 2020 and the requisite majority of the shareholders approved all of the ordinary and special resolutions. Following this, on 24 June 2020 Harmony successfully completed the share placement of 60 278 260 new ordinary shares in Harmony with existing and new institutional investors at a price of R57.50 per share, raising the proceeds of US$200 million ( R3 466 million ). The shares issued represented, in aggregate, approximately 11.1% of Harmony’s issued ordinary share capital before the placing. The placing price represented a discount of 5.4% to the closing share price on 24 June 2020 and a 3.5% discount to the 30-day volume-weighted average price (VWAP). The shares were issued on 30 June 2020 and the proceeds were received on the same day. The share issue costs amounted to R80 million . ACQUISITION AND INTEGRATION COSTS In anticipation of the transaction, Harmony has incurred various costs directly attributable to the acquisition process. These costs include attorney and advisory fees as well as costs related to the bridge loan. The acquisition-related costs are shown as a separate line in the income statement. There have also been costs incurred in preparation for the integration of the acquired assets into Harmony's existing structures and systems. These costs amount to R4 million for the 2020 year and have been included in corporate, administration and other expenditure. ACCOUNTING CONSIDERATIONS Management has performed an initial assessment of the assets to be acquired and has determined that they meet the definition of a business per IFRS 3, Business Combinations (as amended and applicable to Harmony from 1 July 2020). Following the fulfilment of the conditions precedent, management will begin with a fair value exercise in accordance with the requirements of IFRS 3 for the business combinations. The process is expected to take several months to complete. SUBSEQUENT EVENTS Refer to note 38 for developments after the reporting date. ACQUISITION OF THE MOAB KHOTSONG OPERATIONS Effective 1 March 2018 the group acquired the Moab Khotsong and Great Noligwa mines and related infrastructure as well as gold-bearing tailings and the Nufcor uranium plant (collectively the Moab Khotsong operations) from AGA on a going concern basis. The combined assets acquired and liabilities assumed constitute a business as defined by IFRS 3. The cash consideration paid to acquire the Moab Khotsong operations amounted to R3 474 million ( $300 million ). The group incurred acquisition-related costs of R98 million on advisory and legal fees. These costs were recognised as acquisition-related costs in the income statement. Furthermore, the group incurred R63 million on the integration of the operation in 2018 and R8 million in 2019. These costs were recognised as c orporate, administration and other expenditure in the income statement in the relevant years.

Property, Plant and Equipment	PROPERTY, PLANT AND EQUIPMENT SA Rand Figures in million 2020 2019 Mining assets 22 174 20 549 Mining assets under construction 2 714 2 964 Undeveloped properties 4 024 3 965 Other non-mining assets 274 271 Total property, plant and equipment 29 186 27 749 MINING ASSETS ACCOUNTING POLICY Mining assets including mine development costs and mine plant facilities are initially recorded at cost, whereafter they are measured at cost less accumulated depreciation and impairment. Costs include expenditure that is directly attributable to the acquisition of the items. Subsequent costs are included in the asset’s carrying amount or recognised as a separate asset, as appropriate, only when it is probable that future economic benefits associated with the item will flow to the group and the cost of the item can be measured reliably. The net assets of operations placed on care and maintenance are impaired to their recoverable amount. Expenditure on the care and maintenance of these operations is charged against income, as incurred. Mineral and surface use rights represent mineral and surface use rights for parcels of land both owned and not owned by the group. Mineral and surface rights include acquired mineral use rights in production, development and exploration phase properties. The amount capitalised related to a mineral and surface right, either as an individual asset purchase or as part of a business combination, is the fair value at acquisition. The group’s mineral use rights are enforceable regardless of whether proved or probable reserves have been established. In certain limited situations, the nature of use changes from an exploration right to a mining right upon the establishment of proved and probable reserves. The group has the ability and intent to renew mineral use rights where the existing term is not sufficient to recover all identified and valued proved and probable reserves and/or undeveloped mineral interests. Depreciation Depreciation of mining assets is computed principally by the units-of-production method over life-of-mine based on estimated quantities of economically recoverable proved and probable reserves, which can be recovered in future from known mineral deposits. In most instances, proved and probable reserves provide the best indication of the useful life of the group’s mines (and related assets). However, in some instances, proved and probable reserves may not provide a realistic indication of the useful life of the mine (and related assets). This may be the case, for example, where management is confident that further inferred resources will be converted into measured and indicated resources and if they are economically recoverable, they can also be classified as proved and probable reserves. Management is approaching economic decisions affecting the mine on this basis, but has chosen to delay the work required to designate them formally as reserves. In assessing which resources to include so as to best reflect the useful life of the mine, management considers resources that have been included in the life-of-mine plan. To be included in the life-of-mine plan, resources need to be above the cut-off grade set by management, which means that the resource can be economically mined and is therefore commercially viable. This consistent systematic method for inclusion in the life-of-mine plan takes management’s view of the gold price, exchange rates as well as cost inflation into account. In declaring the resource, management would have had to obtain a specified level of confidence of the existence of the resource through drilling as required by the South African Code for Reporting Exploration Results, Mineral Resources and Mineral Reserves (SAMREC). Additional confidence in the existence, commercial viability and economical recovery of such resources may be based on historical experience and available geological information, such as geological information obtained from other operations that are contiguous to the group’s as well as where the group mines continuations of these other operations’ orebodies and reefs. This is in addition to the drilling results obtained by the group and management’s knowledge of the geological setting of the surrounding areas, which would enable simulations and extrapolations to be done with a reasonable degree of accuracy. 13 PROPERTY, PLANT AND EQUIPMENT continued MINING ASSETS continued ACCOUNTING POLICY continued Depreciation continued In instances where management is able to demonstrate the economic recovery of such resources with a high level of confidence, such additional resources, which may also include certain, but not all, of the inferred resources, as well as the associated future development costs of accessing those resources, are included in the calculation of depreciation. The future development costs are those costs that need to be incurred to access these inferred resources, for example the costs to complete a decline or level, which may include infrastructure and equipping costs. These amounts have been extracted from the cash flow projections for the life-of-mine plans. Mineral rights associated with production phase mineral interests are amortised over the life of mine using the units-of-production method in order to match the amortisation with the expected underlying future cash flows. Impairment Testing for impairment is done in terms of the group policy as discussed in note 2.5 . Scrapping of assets Where significant adverse changes have taken place relating to the useful life of an asset, that asset is tested for impairment in terms of the group policy as discussed in note 2.5 . Whether or not an impairment is recognised, it is then necessary to review the useful lives and residual values of the assets within the CGU – this is reviewed at least annually. Where necessary, the useful lives and residual values of the individual assets are revised. Where the useful life of an asset is nil as a result of no future economic benefit expected from the use or disposal of that asset, it is necessary to derecognise the asset. The loss arising from the derecognition is included in profit or loss in the period in which the asset was derecognised. Stripping activities The removal of overburden and other mine waste materials is often necessary during the initial development of an opencast mine site, in order to access the mineral ore deposit. The directly attributable cost of this activity is capitalised in full within mining assets under construction, until the point at which the mine is considered to be capable of commercial production. The removal of waste material after the point at which a mine is capable of commercial production is referred to as production stripping. When the waste removal activity improves access to ore extracted in the current period, the costs of production stripping are charged to the income statement as operating costs in accordance with the principles of IAS 2, Inventories . Where production stripping activity both produces inventory and improves access to ore in future periods the associated costs of waste removal are allocated between the two elements. The portion which benefits future ore extraction is capitalised within stripping and development capital expenditure. If the amount to be capitalised cannot be specifically identified it is determined based on the volume of waste extracted compared with expected volume for the identified component of the orebody. Components are specific volumes of a mine’s orebody that are determined by reference to the life-of-mine plan. In certain instances significant levels of waste removal may occur during the production phase with little or no associated production. The cost of this waste removal is capitalised in full. All amounts capitalised in respect of waste removal are depreciated using the units-of-production method based on proved and probable ore reserves of the component of the orebody to which they relate. The effects of changes to the life-of-mine plan on the expected cost of waste removal or remaining reserves for a component are accounted for prospectively as a change in estimate. 13 PROPERTY, PLANT AND EQUIPMENT continued MINING ASSETS continued CRITICAL ACCOUNTING ESTIMATES AND JUDGEMENTS – GOLD MINERAL RESERVES AND RESOURCES Gold mineral reserves and resources are estimates of the amount of ounces that can be economically and legally extracted from the group’s properties. In order to calculate the gold mineral reserves and resources, estimates and assumptions are required about a range of geological, technical and economic factors, including quantities, grades, production techniques, recovery rates, production costs, commodity prices and exchange rates. Estimating the quantities and/or grade of the reserves and resources requires the size, shape and depth of the orebodies to be determined by analysing geological data such as the logging and assaying of drill samples. This process may require complex and difficult geological judgements and calculations to interpret the data. Because the economic assumptions used to estimate the gold mineral reserves and resources change from year to year, and because additional geological data is generated during the course of operations, estimates of the mineral reserves and resources may change from year to year. Changes in the reserves and resources may affect the group’s financial results and financial position in a number of ways, including: • Asset carrying values may be affected due to changes in estimated cash flows; • Scrapping of assets to be recorded in the income statement following the derecognition of assets as no future economic benefit expected; • Depreciation and amortisation charged in the income statement may change as they are calculated on the units-of-production method; • Environmental provisions may change as the timing and/or cost of these activities may be affected by the change in mineral reserves; and • Useful life and residual values may be affected by the change in mineral reserves. At the end of each financial year, the estimate of proved and probable gold mineral reserves and resources is updated. Depreciation of mining assets is prospectively adjusted, based on these changes. SENSITIVITY ANALYSIS – GOLD MINERAL RESERVES AND RESOURCES EFFECT ON DEPRECIATION The group includes certain inferred resources in the denominator and future development costs in the numerator when performing the depreciation calculation for certain of its operations, where proved and probable reserves alone do not provide a realistic indication of the useful life of mine (and related assets). During periods presented, this mainly related to Doornkop. Had the group only used proved and probable reserves in its calculations, depreciation for 2020 would have amounted to R3 533 million ( 2019 : R4 116 million ) ( 2018 : R2 753 million ), compared with the reported totals of R3 508 million ( 2019 : R4 054 million ) ( 2018 : R2 570 million ). CRITICAL ACCOUNTING ESTIMATES AND JUDGEMENTS – PRODUCTION START DATE Various relevant criteria are considered in order to assess when the mine is substantially complete and ready for its intended use and moves into the production phase. Some of the criteria would include but are not limited to the following: • The level of capital expenditure compared to the total project cost estimates; • The ability to produce gold in a saleable form (where more than an insignificant amount of gold has been produced); and • The ability to sustain the ongoing production of gold. CRITICAL ACCOUNTING ESTIMATES AND JUDGEMENTS – STRIPPING ACTIVITIES The determination of the volume of waste extracted and the expected volume for the identified component of the orebody is dependent on an individual mine’s design and life-of-mine plan and therefore changes to the design or life-of-mine plan will result in changes to these estimates. Identification of the components of a mine’s orebody is made by reference to the life-of-mine plan. The assessment depends on a range of factors including each mine’s specific operational features and materiality. 13 PROPERTY, PLANT AND EQUIPMENT continued MINING ASSETS continued CRITICAL ACCOUNTING ESTIMATES AND JUDGEMENTS – IMPAIRMENT OF ASSETS The recoverable amount of mining assets is generally determined utilising real discounted future cash flows (post tax). Management also considers such factors as the quality of the individual orebody, market risk, asset specific risks and country risk in determining the fair value. Key assumptions for the calculations of the mining assets’ recoverable amounts are the commodity prices, resource values, marketable discount rates, costs to sell, exchange rates and the annual life-of-mine plans. In determining the commodity prices and resource values to be used, management assesses the long-term views of several reputable institutions on commodity prices and based on this, derives the commodity prices and resource values. The life-of-mine plans are based on the proved and probable reserves as included in the Reserve Declaration, which are determined in terms of SAMREC, as well as resources where management has high confidence in the orebody and economical recovery of gold, based on historic and similar geological experience. During the year under review, the group calculated the recoverable amounts (generally fair value less costs to sell) based on updated life-of-mine plans and the following gold price, silver price and exchange rates assumptions: 2020 2019 2018 US$ gold price per ounce – Year 1 1 610 1 325 1 250 – Year 2 1 558 1 310 1 250 – Year 3 1 469 1 290 1 250 – Long term (Year 4 onwards) 1 350 1 290 1 250 US$ silver price per ounce – Year 1 and Year 2 17.00 15.75 17.00 – Long term (Year 3 onwards) 17.00 17.00 17.00 Exchange rate (R/US$) – Year 1 16.72 14.43 13.30 – Year 2 15.47 14.25 13.30 – Year 3 15.29 14.11 13.30 – Long term (Year 4 onwards) 14.51 14.11 13.30 Exchange rate (PGK/US$) 3.45 3.34 3.17 Rand gold price (R/kg) – Year 1 865 000 615 000 535 000 – Year 2 775 000 600 000 535 000 – Year 3 722 000 585 000 535 000 – Long term (Year 4 onwards) 630 000 585 000 535 000 The following is the attributable gold resource value assumption: South Africa Hidden Valley US dollar per ounce 2020 2019 2018 2020 2019 2018 Measured 25.00 25.00 25.00 n/a n/a n/a Indicated 8.00 8.00 8.00 8.00 8.00 5.84 Inferred 2.80 2.80 2.80 n/a n/a 5.84 The recoverable amount of mining assets is determined utilising real discounted future cash flows or resource multiples in the case of undeveloped properties and certain resource bases. One of the most significant assumptions that influence the group's operations' life-of-mine plans, and therefore the impairment assessment, is the expected gold price. Due to the increase in the US$ commodity price and weakening of the rand against the US$ at the end of the financial year, management decided it would be appropriate to differentiate between short-, medium- and long-term assumptions used in the models. 13 PROPERTY, PLANT AND EQUIPMENT continued MINING ASSETS continued CRITICAL ACCOUNTING ESTIMATES AND JUDGEMENTS – IMPAIRMENT OF ASSETS continued The long-term price was determined as part of the annual budgeting process and is used in the life-of-mine plans and is also the cut-off price for calculating reserves included in the declaration of reserves and resources in terms of SAMREC. The resource multiple values are unchanged from the prior year, given the long-term nature of the projects that are valued in this manner. Due to the volatilities experienced in the markets and the uncertainty in forecasting future cash flows due to the impact of the COVID-19 pandemic, management has used various probability scenarios in determining the recoverable amounts for the CGUs at 30 June 2020. The following were factored into management's judgements: • Infection rates and the timing of the expected peaks in the provinces that Harmony's operations are situated in, based on models prepared by the South African government; • Expected disruptions to production together with the mitigation strategies management has in place; • Potential duration of the impact of the virus and the related restrictions in operations; and • Potential changes of the timing of various cash flows due to shortened production breaks. Management included estimates of the staffing costs for screening and monitoring employees at work as well as those that are in quarantine. The cost estimates also include the accommodation expenses for employees in quarantine or isolation as well as the treatment cost for those with mild symptoms and those with severe symptoms that need to be hospitalised. These estimates were based on actual costs incurred for the period March to June 2020. In preparing the various scenarios, management considered and varied: • The potential impact on production and therefore on the revenue cash flows, based on historical trends that have been extrapolated to account for varying disruption levels; • The duration of potential disruptions to production, ranging from 12 months to 24 months; • The infection rates and associated costs. Where infections were assumed to continue into Year 2, the rate was dependant on the assumed infections in Year 1, with a higher rate in Year 1 resulting in a lower rate in Year 2, and vice versa. Management assumed that the production costs would be largely unaffected as employees would either be at work or on sick leave, while the strategy of moving crews around would ensure production carried on without undue disruption and therefore would not impact on costs such as consumables and electricity. The calculated cash flows were then weighted based on management's expectation of each of the scenarios occurring. Th e resulting amounts were discounted using the specific discount rate for each operation in order to determine the recoverable amount. The post-tax real discount rate for Hidden Valley was 9.02% ( 2019 : 10.13% ) ( 2018 : 9.91% ) and the post-tax real discount rates for the South African operations ranged between 9.62% and 11.53% ( 2019 : 8.90% and 11.10% ) ( 2018 : 8.35% and 10.25% ), depending on the asset, were used to determine the recoverable amounts. Cash flows used in the impairment calculations are based on life-of-mine plans which exceed five years for the majority of the mines. Cash flows from potential projects, life-of-mine extensions and residual ounces can also be included in the impairment assessment where deemed appropriate. An additional risk premium is added to the post-tax real discount rates in these instances. Refer to note 6 for details of impairment testing performed and impairments recorded. Should management’s estimate of the future not reflect actual events, further impairments may be identified. Factors affecting the estimates include: • Changes to proved and probable ore reserves; • Economical recovery of resources; • The grade of the ore reserves may vary significantly from time to time; • Review of strategy; • Unforeseen operational issues at the mines; • Differences between actual commodity prices and commodity price assumptions; • Changes in the discount rate and foreign exchange rates; • Changes in capital, operating mining, processing and reclamation costs; • Mines' ability to convert resources into reserves; • Potential production stoppages for indefinite periods; • The impact of the COVID-19 pandemic on the global economy, commodity prices and exchange rates, as well as the impact in the countries the group operates in, resulting in production curtailment; and • Carbon tax. 13 PROPERTY, PLANT AND EQUIPMENT continued MINING ASSETS continued SENSITIVITY ANALYSIS - IMPAIRMENT OF ASSETS One of the most significant assumptions that influence the life-of-mine plans and therefore the impairment assessment is the expected commodity prices. The sensitivity scenario of a 10% decrease or increase in the commodity price used in the discounted cash flow models and the resource values used (with all other variables held constant) would have resulted in the following impairment being recorded as at 30 June 2020 and 2019 : SA Rand Figures in million 2020 2019 - 10% decrease Tshepong Operations 3 352 7 155 Target 1 804 1 278 Joel 716 984 Kusasalethu 441 1 962 Bambanani 1 94 331 Other Freegold assets 20 — Moab Khotsong 1 15 2 758 Unisel 6 45 Doornkop — 1 350 Hidden Valley — 749 Target 3 — 337 Target North — 291 Other surface operations — 178 Masimong — 105 Kalgold — 39 + 10% increase Target 3 — 300 1 The carrying amounts of these CGUs include goodwill and any impairment losses are allocated first to goodwill and then to the identifiable assets. At all other operations, a 10% increase in the gold price would have resulted in no impairments being recorded. 13 PROPERTY, PLANT AND EQUIPMENT continued MINING ASSETS continued The movement in the mining assets is as follows: SA Rand Figures in million 2020 2019 Cost Balance at beginning of year 53 629 49 741 Fully depreciated assets no longer in use derecognised — (302 ) Additions 1 3 180 4 113 Disposals (85 ) (16 ) Scrapping of assets (268 ) (117 ) Adjustment to rehabilitation asset (48 ) (439 ) Transfers and other movements 1 348 801 Translation 1 980 (152 ) Balance at end of year 59 736 53 629 Accumulated depreciation and impairments Balance at beginning of year 33 080 25 538 Fully depreciated assets no longer in use derecognised — (302 ) Impairment of assets — 3 880 Disposals (70 ) (16 ) Scrapping of assets (206 ) (96 ) Depreciation 3 563 4 184 Translation 1 195 (108 ) Balance at end of year 37 562 33 080 Net carrying value 22 174 20 549 1 Included in additions for 2020 is an amount of R97 million ( 2019 : R173 million ) for capitalised depreciation associated with stripping activities at the Hidden Valley operations. Loss on scrapping of property, plant and equipment Refer to note 7 for details. Stripping activities Included in the balance for mining assets is an amount of R84 million ( 2019 : R48 million ) relating to Kalgold and R598 million (2019: R1 160 million ) relating to Hidden Valley. Depreciation of R17 million ( 2019 : R13 million ) and R668 million (2019: R89 million ) was recorded for Kalgold and Hidden Valley respectively. Transfer of assets Transfer of assets mainly relates to assets under construction transferred to mining assets. Hidden Valley During the 2020 year an amount of R438 million (2019: R607 million ) was transferred to mining assets at Hidden Valley. This related to ongoing mining development costs. Joel At 1 January 2020, management performed an assessment of Joel's Level 137 decline project to determine whether it had reached commercial levels of production. It was considered substantially complete and ready for its intended use as: • Capital expenditure is 98% of project cost estimates; • More than an insignificant amount of gold is being produced in a saleable form; and • The level has the ability to sustain the ongoing production of gold. The capitalisation of borrowing costs ceased and depreciation commenced as of 1 January 2020. An amount of R897 million was transferred to mining assets. MINING ASSETS UNDER CONSTRUCTION ACCOUNTING POLICY At the group’s surface mines, when it has been determined that a mineral property can be economically developed as a result of establishing proved and probable reserves, costs incurred to develop the property are capitalised as incurred until the mine is considered to have moved into the production phase. These costs include costs to further delineate the orebody and remove overburden to initially expose the orebody. At the group’s underground mines, all costs incurred to develop the property, including costs to access specific ore blocks or other areas of the underground mine, are capitalised to the extent that such costs will provide future economic benefits. These costs include the cost of shaft sinking and access, the costs of building access ways, lateral development, drift development, ramps, box cuts and other infrastructure development. Revenue earned during the pre-production phase is credited to the asset. Where a depreciable asset is used in the construction or extension of a mine, the depreciation is capitalised against the mine’s cost. Exploration properties acquired are recognised in the balance sheet within development cost and are shown at cost less provisions for impairment determined in accordance with the group’s accounting policy on impairment of non-financial assets. Mineral interests associated with development and exploration phase mineral interests are not amortised until such time as the underlying property is converted to the production stage. Capitalisation of pre-production costs ceases when commercial levels of production are reached. Commercial levels of production are discussed under “production start date” above. CRITICAL ACCOUNTING ESTIMATES AND JUDGEMENTS – EXPLORATION AND EVALUATION ASSETS The recoverability of exploration and evaluation expenditure is assessed at the end of each reporting period. Significant judgement is required as to whether an area of activity is to be carried forward on the balance sheet, or written off through the identification of areas of activity which have not yet reached a stage that permits a reasonable assessment of the existence of economically recoverable reserves, where there is no continuing significant activity plan in relation to the area. The movement in the mining assets under construction is as follows: SA Rand Figures in million 2020 2019 Cost Balance at beginning of year 2 964 2 528 Additions 687 1 070 Depreciation capitalised 1 4 50 Finance costs capitalised 2 54 133 Transfers and other movements (1 334 ) (802 ) Translation 339 (15 ) Balance at end of year 2 714 2 964 1 2020 relates to Tshepong only. 2019 relates primarily to Hidden Valley. 2 Refer to note 9 for further detail on the capitalisation rate applied. Wafi-Golpu development Capitalisation of certain project expenses on Wafi-Golpu was halted from 1 July 2019 following delays in the permitting of the project (see below). The ongoing expenses in the 2020 financial year were for holding purposes and did not result in future economic benefit. These have been included in exploration expenditure in the income statement and amounted to R123 million for the 2020 year. 13 PROPERTY, PLANT AND EQUIPMENT continued MINING ASSETS UNDER CONSTRUCTION continued Wafi-Golpu development continued Following submission of the Special Mining Lease (SML) and Environment Impact Statement applications to the regulators in March 2018 and July 2018 respectively, the Wafi-Golpu joint operation entered into a memorandum of agreement with the Papua New Guinea government (the State) in December 2018, targeting an SML grant by June 2019. The milestones set for assessment of the applications and associated permitting work streams are not being achieved, and as a result the project permitting roadmap and timeline remain uncertain. Delays in discussions with the State are attributed to the judicial review of the memorandum of agreement initiated by the Governor of the Morobe Province in May 2019. This judicial review was concluded on 11 February 2020 with the National Court dismissing the case on the basis that the State’s withdrawal from the memorandum of agreement rendered the matter nugatory. The stay order issued by the National Court in that connection was lifted. On 20 March 2020, the Morobe Governor appealed the dismissal of the action to the Papua New Guinea Supreme Court, and intends to seek reinstatement of the stay order. Management is confident that the permitting process will continue, given the progress to date on the various agreements required for the permitting process and granting of a Special Mining Licence. Key permitting activities are continuing and are fully supported and resourced. UNDEVELOPED PROPERTIES ACCOUNTING POLICY Undeveloped properties are initially recognised at cost, which is generally based on the fair value of resources obtained through acquisitions. The carrying values of these properties are tested annually for impairment. Once development commences, these properties are transferred to mining properties and accounted for in accordance with the related accounting policy. The movement in the undeveloped properties is as follows: SA Rand Figures in million 2020 2019 Cost Balance at beginning of year 5 437 5 446 Translation 62 (9 ) Balance at end of year 5 499 5 437 Accumulated depreciation and impairments Balance at beginning and end of year 1 472 1 472 Translation 3 — Balance at end of year 1 475 1 472 Net carrying value 4 024 3 965 OTHER NON-MINING ASSETS ACCOUNTING POLICY Land is shown at cost and not depreciated.

Disclosure of detailed information about intangible assets [abstract]
Intangible Assets	INTANGIBLE ASSETS ACCOUNTING POLICY Intangible assets consist of all identifiable non-monetary assets without physical substance. They are stated at cost less accumulated amortisation and accumulated impairment losses, if any. The following are the main categories of intangible assets: Goodwill Goodwill is an intangible asset with an indefinite useful life which is not amortised but tested for impairment on an annual basis, or when there is an indication of impairment. The excess of consideration transferred over the amount of any non-controlling interest in the acquiree and the acquisition-date fair value of any previously held equity interest in the acquiree over the fair value of the group’s share of the identifiable net assets acquired is recorded as goodwill. Goodwill on acquisition of subsidiaries, joint operations and businesses is included in intangible assets. Goodwill on acquisition of associates is included in investments in associates and tested for impairment as part of the overall balance. Goodwill is tested annually for impairment and carried at cost less accumulated impairment losses. Goodwill is allocated to cash generating units for the purpose of impairment testing. The allocation is made to those cash generating units or groups of cash generating units that are expected to benefit from the business combination in which the goodwill arose. If the composition of one or more cash generating units to which goodwill has been allocated changes due to a re-organisation, the goodwill is re-allocated to the units affected. The gain or loss on disposal of an entity includes the carrying amount of goodwill relating to the entity sold. Technology-based assets Acquired computer software licences that require further internal development are capitalised on the basis of costs incurred to acquire and bring to use the specific software. These technology-based assets are classified as intangible assets with a finite useful life. These assets are amortised on a straight-line basis over their estimated useful lives, which are reviewed annually, as follows: • Computer software at 20% per year. CRITICAL ACCOUNTING ESTIMATES AND JUDGEMENTS - IMPAIRMENT OF GOODWILL Due to the wasting nature of mining assets and the finite life of a mine's reserves, the allocation of goodwill to a mine or cash generating unit will eventually result in an impairment charge for the goodwill.

The trusts are consolidated into the group as the group exercises control of the trusts. The measurement of the investments held by the trust funds is dependent on their classification under financial assets. Income received and gains are treated in accordance with these classifications. The equity-linked notes are classified and measured at fair value through profit or loss whilst the interest-bearing short-term investments are classified and measured as debt instruments at amortised cost. The environmental trust funds are irrevocable trusts under the group's control. Contributions to the trusts are invested in interest-bearing short-term and medium-term cash investments and medium term equity-linked notes issued by commercial banks that provide guaranteed interest and additional interest or growth linked to the growth of the Top 40 index of the JSE. These investments provide for the estimated cost of rehabilitation at the end of the life of the group's mines. Income earned on the investments is retained in the funds and reinvested.

Harmony is a concurrent creditor in the Pamodzi Orkney liquidation. 17 OTHER NON-CURRENT ASSETS continued (b) During 2016, Harmony advanced R200 million to the ARM BBEE Trust, a shareholder of African Rainbow Minerals Limited (ARM). The trust is controlled and consolidated by ARM, who holds 12.38% of Harmony's shares at 30 June 2020. Harmony is a trustee of the ARM BBEE Trust. The loan is subordinated and unsecured. The interest is market related (3 months JIBAR plus 4.25% ) and is receivable on the maturity of the loan on 31 December 2022. On adoption of IFRS 9 in 2019, it was assessed that the contractual cash flows fail the solely payments of principal and interest (SPPI) characteristics an d that the loan will therefore be carried at fair value through profit or loss and t he previously recognised provision was derecognised.The group determined that the contractual terms include exposure to risk and volatility that is inconsistent with a basic lending arrangement. In making this assessment the group considered contingent events that would change the amount and timing of cash flows and potential limits on the group's claim to cash flows from specified assets (e.g. non-recourse asset arrangements). At 30 June 2020 the loan has been remeasured to its fair value of R306 million (2019: R271 million ) using a discounted cash flow model. The fair value adjustment is recorded in gains on financial instruments - refer to note 8 . (c) On adoption of IFRS 9 on 1 July 2018, an irrevocable election was made to classify the equity instruments previously classified as available-for-sale as at FVOCI. The new standard impacted the measurement of the group's unquoted equity investments as IFRS 9 eliminated the exemption provided under IAS 39 where unquoted equity investments were measured at cost when fair value could not be reliably measured. This change resulted in revaluing the unlisted investment in Rand Mutual Assurance, which had a cost of Rnil to fair value of R82 million in 2019. The difference between the carrying amounts of financial instruments before the adoption of IFRS 9 and the new carrying amount calculated in accordance with the standard at 1 July 2018 was recognised directly in the opening balance of equity. Refer to the statements of changes in equity. The movement in the investment in Rand Mutual Assurance is as follows: SA Rand Figures in million 2020 2019 Balance at beginning of year 52 — Fair value on adoption of IFRS 9 — 82 Capital dividend received (7 ) (30 ) Fair value gain 24 — Balance at end of year 69 52 On 6 December 2019, RMA declared a dividend that relates to the first tranche of the contingent consideration for the sale of shares in one of its subsidiaries.The dividend is seen as a recovery of capital as it reduced Harmony's effective share in the investment. The dividend relating to the second tranche of the contingent consideration is expected to be received during the 2021 financial year. The fair value gains are a result of the favourable financial position of the total investment. Please refer to note 37 on the fair value valuation technique.

Cash flow hedge accounting is applied to the majority of these contracts, resulting in the effective portion of the unrealised gains and losses being recorded in other comprehensive income (other reserves - refer to note 24 ). Refer to note 37 for a summary of the risk management strategy applied and the balances relating to designated hedging instruments as at reporting date. Hedge effectiveness is determined at the inception of the hedge relationship and through periodic prospective effectiveness assessments. The group enters into gold forward contracts that have similar terms as the hedged item, such as notional amount, maturity date and reference gold spot price thereby ensuring that an economic relationship exists between the hedging instrument and the hedged item and resulting in a hedge ratio of 1 :1. Potential sources of hedge ineffectiveness include counterparty and own credit risk, day one gains and losses, a mismatch in the timing of the derivative and underlying gold sale maturities, location differential and the refining margin. Hedge ineffectiveness is measured by comparing the change in the expected cash flows from a forward sale contract versus the sale of an equivalent quantity of gold in the open market. Ineffectiveness results when the changes in the fair values in the hedging instruments exceed the fair value changes in the hedged item. A negligible amount of hedge ineffectiveness was experienced in the years presented. The gains and losses from derivative contracts to which hedge accounting is not applied is included in gains/(losses) on derivatives in profit or loss. (a) Rand gold contracts Discontinuance of hedge accounting As a result of the original 21-day lockdown announced in South Africa, effective 27 March 2020, aimed to slow the spread of COVID-19, Harmony placed all deep-level underground mines in South Africa on care and maintenance. As a result, a significant volume of the underlying exposure that was originally intended to be hedged was delayed. A total of 63 400 ounces of gold forwards were originally set to mature in the months of April and May 2020. After assessing forecasts of gold production at 1 April 2020, the hedged items, being the sales of gold, relating to 30 500 ounces of gold forwards were assessed to no longer be probable. The hedged items relating to the remaining balance of gold forwards were still considered to be highly probable. Due to the fact that the occurrence of the forecast transactions/hedged items were no longer considered probable, there was no longer an effective hedging relationship and therefore hedge accounting for these hedges was discontinued. Unrealised losses relating to the hedges amounting to R48 million and R187 million of restructured contracts discussed below, previously recognised in other comprehensive income, were immediately reclassified to profit or loss as gains/losses on derivatives. Restructuring of contracts In response to the gold forwards’ hedged items no longer being probable and in order to better match the cash flows relating to the underlying exposure, certain of the Rand gold forwards with maturities between 15 April 2020 and 31 May 2020 were effectively extended to mature between the periods July 2020 and March 2021. The restructured gold forwards retained the pricing of the original forwards. They were not designated as hedging instruments as the difference in the costing structure would have required a different effectiveness assessment than currently used by management. Unrealised losses relating to the hedges amounting to R187 million , previously recognised in other comprehensive income, were immediately reclassified to profit or loss as gains/losses on derivatives. All future gains and losses on the restructured hedges will be recognised in profit or loss. Subsequently, losses of R70 million have been recognised in profit or loss. (b) US$ commodity contracts Harmony maintains a derivative programme for Hidden Valley by entering into commodity derivative contracts. The contracts comprise US$ gold forward sale contracts as well as silver zero cost collars which establish a minimum (floor) and maximum (cap) silver sales price. Hedge accounting is applied to all US$ gold forward sale contracts entered into from 1 January 2019 and these are shown separately from the silver zero cost collars that are not hedge accounted. (c) Foreign exchange contracts Harmony maintains a foreign exchange derivative programme in the form of zero cost collars, which sets a floor and cap Rand/US$ exchange rate at which to convert US dollars to Rands, and foreign exchange forward contracts. Hedge accounting is not applied to these contracts. 18 DERIVATIVE FINANCIAL INSTRUMENTS continued The following table shows the open position at the reporting date: FY2021 FY2022 TOTAL Q1 Q2 Q3 Q4 Q1 Q2 Q3 Q4 Foreign exchange contracts Zero cost collars US$m 116 115 99 65 47 42 27 — 511 Average Floor 15.36 15.40 15.44 15.91 16.32 16.93 17.99 — 15.81 Average Cap 16.45 16.58 16.62 17.28 17.90 18.54 19.65 — 17.09 Forward contracts US$m 66 44 35 12 9 9 8 — 183 Average Forward rate 15.83 15.82 16.13 16.93 18.18 18.41 18.71 — 16.38 R/gold '000 oz - restructured 8 8 8 — — — — — 24 '000 oz - cash flow hedge 80 78 77 71 61 44 25 10 446 Average R'000/kg 673 679 691 737 806 851 950 1037 743 US$/gold '000 oz - cash flow hedge 12 12 12 12 12 12 10 5 87 Average US$/oz 1 413 1 442 1 489 1 521 1 561 1 606 1 710 1 760 1 543 Total gold '000 oz 100 98 97 83 73 56 35 15 557 US$/silver '000 oz 360 340 300 270 230 90 10 — 1 600 Average Floor 17.47 17.87 18.01 18.17 18.21 17.86 18.40 — 17.91 Average Cap 18.92 19.37 19.50 19.70 19.75 19.44 20.15 — 19.41 Refer to note 37 for the details on the fair value measurements.

Investments in Associates	INVESTMENTS IN ASSOCIATES CRITICAL ACCOUNTING ESTIMATES AND JUDGEMENTS The investments in associates are evaluated for impairment by comparing the entire carrying value of the investment (including loans to associates and preference shares) to the recoverable amount, which is the higher of value in use or fair value less costs to sell. Discounted cash flow models are used to calculate the net present value of the investments. The cash flows in the models include expected interest and capital payments on loans, dividends, redemption amounts and proceeds on disposal. (a) Harmony acquired a 32.4% interest in Pamodzi on 27 February 2008, initially valued at R345 million . Pamodzi was listed on the JSE and had interests in operating gold mines in South Africa. Pamodzi was placed in liquidation in March 2009. As at 30 June 2020, the liquidation process has not been concluded. Refer to note 17 (a) for details of the loan and provision of impairment of the loan. (b) Rand Refinery provides precious metal smelting and refining services in South Africa. Harmony holds a 10.38% share in Rand Refinery. This investment is a strategic investment for the group as Rand Refinery is the only company that provides such services in South Africa. Although the group holds less than 20% of the equity shares of Rand Refinery, the group is able to exercise significant influence by virtue of having a right to appoint a director on the board. Through the 10.38% shareholding and the right to appoint a director on the board, the investment has been accounted for as an associate. In December 2014, Rand Refinery drew down on a shareholder's loan of which Harmony's portion thereof was R120 million . Following an amended loan agreement signed in June 2017, the loan was converted into cumulative redeemable preference shares of no par value. During 2020, Rand Refinery redeemed preference shares to the value of R58 million (2019: R32 million ). Rand Refinery has a 31 August financial year-end. The movement in the investments in associates during the year is as follows: SA Rand Figures in million 2020 2019 Balance at beginning of year 110 84 Redemption of preference shares (58 ) (32 ) Share of profit in associate 94 59 Balance at end of year 146 110

Investment in Joint Operations	INVESTMENT IN JOINT OPERATIONS The group has a 50% interest in certain mining and exploration assets located in the Morobe province, PNG. Newcrest Mining Limited owns the remaining 50% interest in these assets. The asset in the joint arrangement is the Wafi-Golpu project. The joint arrangement is accounted for as a joint operation. Under the conditions of the Wafi-Golpu exploration tenements, the State has reserved the right prior to the commencement of mining to take up an equity interest of up to 30% of any mineral discovery within the Wafi-Golpu tenements. The right is exercisable by the State once at any time prior to the commencement of mining. If the State exercises this right, the exercise price is a pro-rata share of the accumulated exploration expenditure. Once the right is exercised, the State is responsible for its proportionate share of ongoing exploration and project development costs. During February 2012, the State indicated its intention to exercise its option. As at 30 June 2020, this option has not been exercised. The carrying amount of the project amounts to R3.0 billion at 30 June 2020.

Inventories [Abstract]
Inventories	INVENTORIES ACCOUNTING POLICY Inventories, which include bullion on hand, gold-in-process, gold in lock-up, ore stockpiles and consumables, are measured at the lower of cost and net realisable value. Net realisable value is assessed at each reporting date and is determined with reference to relevant market prices. The cost of bullion, gold-in process and gold in lock-up is determined by reference to production cost, including amortisation and depreciation at the relevant stage of production. Ore stockpiles are valued at average production cost. Stockpiles and gold in lock-up are classified as non-current assets where the stockpile's volume exceeds current processing capacity and where a portion of static gold in lock-up is expected to be recovered more than 12 months after balance sheet date. Gold in-process inventories represent materials that are currently in the process of being converted to a saleable product. In-process material is measured based on assays of the material fed to process and the projected recoveries at the respective plants. In-process inventories are valued at the average cost of the material fed to process attributable to the source material coming from the mine or stockpile plus the in-process conversion costs, including the applicable depreciation relating to the process facility, incurred to that point in the process. Gold in-process includes gold in lock-up which is generally measured from the plants onwards. Gold in lock-up is expected to be extracted when plants are demolished at the end of their useful lives, which is largely dependent on the estimated useful life of the operations feeding the plants. At the group’s open pit operations, gold in-process represents production in broken ore form. Consumables are valued at weighted average cost value after appropriate allowances for slow moving and redundant items. CRITICAL ACCOUNTING ESTIMATES AND JUDGEMENTS Judgement is applied in estimating the provision for stock obsolescence. The provision is recognised on items not considered critical as a percentage of the value of the inventory depending on the period elapsed since the inventory was purchased or issued. Inventory held for longer than five years is written down to zero unless there is sufficient evidence of a recoverable amount. SA Rand Figures in million 2020 2019 Gold in lock-up 47 43 Gold in-process, ore stockpiles and bullion on hand (a) 936 780 Consumables at weighted average cost (net of provision) (b) 1 485 1 187 Total inventories 2 468 2 010 Non-current portion of gold in lock-up and gold in-process (47 ) (43 ) Total current portion of inventories 2 421 1 967 Included in the balance above is: Inventory valued at net realisable value 47 334 (a) The run-of-mine (ROM) stock at the Hidden Valley operations increased R294 million year on year following the commencement of the stage 6 cut-back. The increase includes approximately R72 million which is attributable to translation. This was offset by gold in-process which decreased R169 million year on year due to the lower production during the last quarter of the 2020 financial year as well as the plants being cleaned out during the South African COVID-19 national lockdown. (b) The consumables’ balance increased R298 million year on year, primarily as a result of the impact of the weakening of the Rand against the Australian dollar from R9.91 /A$1 at 30 June 2019 to R11.96 /A$1 at 30 June 2020 and the resultant movement when translating the balance for the Hidden Valley operations at year-end. During the year, an increase of R51 million ( 2019 : R1 million decrease) to the provision for slow-moving and redundant stock was made. The total provision at 30 June 2020 was R331 million ( 2019 : R281 million ).

SHARE ISSUES Share placing During June 2020, Harmony conducted a placement of ordinary shares with existing and new institutional investors . A total of 60 278 260 new ordinary shares were placed at a price of R57.50 per share, raising gross proceeds of approximately R3.466 billion . The Placing Shares issued represent, in aggregate, approximately 11.1% of the group's issued ordinary share capital before the Placing. The Placing Price represents a discount of 5.4% to the closing share price on 24 June 2020 and a 3.5% discount to the 30-day volume-weighted average price (VWAP) . The Placing Shares rank pari passu in all respects with the existing Harmony ordinary shares, including the right to receive all dividends and other distributions declared, made or paid after the date of issue thereof. The proceeds of the Placing will be used by Harmony to discharge the US$200 million cash consideration to acquire AGA's remaining South African assets (refer to note 12 ). The share issue costs amounted to R80 million . Accelerated bookbuild During June 2018, Harmony conducted a placement of 55 055 050 new ordinary shares to qualifying investors through an accelerated bookbuild. ARM subscribed for an additional 11 032 623 shares at R19.12 a share, totalling R211 million , in July 2018. The issue resulted in ARM maintaining its shareholding of 14.29% post the placement of shares. In total, gross proceeds of R1.26 billion were raised to fund part of the outstanding bridge loan raised for the acquisition of the Moab Khotsong operations. Share issues relating to employee share options An additional 3 023 251 ( 2019 : 21 856 821 ) shares were issued to settle the exercise of share options by employees relating to Harmony's management share option schemes. During the 2019 financial year, Harmony implemented a new employee share option scheme referred to as the Sisonke Employee Share Ownership Plan. An amount of 6 700 000 shares were issued to the Harmony ESOP Trust as part of the new scheme. Note 34 sets out the details in respect of the share option schemes. Convertible preference shares On 20 February 2019, Harmony issued 4 400 000 convertible preference shares to the Harmony Gold Community Trust. The convertible preference shares carry a minimum annual preference dividend of R2 per share and are convertible into o rdinary shares on a 1 :1 basis after the tenth anniversary of the date on which the shares were issued. The conversion is at the election of Harmony. 23 SHARE CAPITAL continued TREASURY SHARES Included in the total of issued shares are the following treasury shares: Number of shares 2020 2019 Ordinary shares Lydenburg Exploration Limited 1 335 335 Kalgold Share Trust 2 47 046 47 046 Harmony ESOP Trust 2 6 335 629 6 592 900 Convertible preference shares Harmony Gold Community Trust 3 4 400 000 4 400 000 1 A wholly-owned subsidiary. 2 Trust controlled by the group. 3 The issue of the convertible preference shares did not impact the group's consolidated financial statements as the Harmony Gold Community Trust is controlled by the group.

Provision For Environmental Rehabilitation [Abstract]
Provision for Environmental Rehabilitation	PROVISION FOR ENVIRONMENTAL REHABILITATION ACCOUNTING POLICY Estimated long-term environmental obligations, comprising pollution control, rehabilitation and mine closure, are based on the group’s environmental management plans in compliance with current technological, environmental and regulatory requirements. Based on disturbances to date, the net present value of expected rehabilitation cost estimates is recognised and provided for in full in the financial statements. The estimates are reviewed annually and are discounted using a pre-tax risk-free rate that is adjusted to reflect the current market assessments of the time value of money and the risks specific to the obligation. Annual changes in the provision consist of finance costs relating to the change in the present value of the provision and inflationary increases in the provision estimate, as well as changes in estimates. The present value of environmental disturbances created are capitalised to mining assets against an increase in the rehabilitation provision. If a decrease in the liability exceeds the carrying amount of the asset, the excess is recognised immediately in the income statement. If the asset value is increased and there is an indication that the revised carrying value is not recoverable, impairment is performed in accordance with the accounting policy dealing with impairments of non-financial assets (refer to note 2.5 ). Rehabilitation projects undertaken included in the estimates are charged to the provision as incurred. The cost of ongoing current programmes to prevent and control pollution is charged against income as incurred. Over time, the liability is increased to reflect an interest element, and the capitalised cost is depreciated over the life of the related asset. 25 PROVISION FOR ENVIRONMENTAL REHABILITATION continued CRITICAL ACCOUNTING ESTIMATES AND JUDGEMENTS Significant judgement is applied in estimating the ultimate rehabilitation cost that will be required in future to rehabilitate the group’s mines, related surface infrastructure and tailings dams. Ultimate cost may significantly differ from current estimates. The following rates were used in the calculation of the provision: 2020 2019 2018 % % % South African operations Inflation rate - short term (Year 1 and Year 2) 4.50 5.25 5.50 - long term (Year 3 onwards) 5.00 5.25 5.50 Discount rates - 12 months 3.90 6.50 6.70 - one to five years 5.55 6.85 7.00 - six to nine years 8.20 8.50 8.20 - ten years or more 10.95 9.60 8.60 PNG operations: Inflation rate 6.28 5.00 6.00 Discount rate 5.50 6.25 6.25 The group’s mining and exploration activities are subject to extensive environmental laws and regulations. The group has made, and expects to make in the future, expenditures to comply with such laws and regulations, but cannot predict the full amount of such future expenditures. Estimated future reclamation costs are based principally on legal and regulatory requirements. The following is a reconciliation of the total provision for environmental rehabilitation: SA Rand Figures in million 2020 2019 Balance at beginning of year 3 054 3 309 Change in estimate - Balance sheet 1 (48 ) (439 ) Change in estimate - Income statement 47 33 Utilisation of provision (47 ) (86 ) Time value of money and inflation component of rehabilitation costs 194 208 Transfer — 37 Translation 208 (8 ) Balance at end of year 3 408 3 054 1 In 2019 the biggest contributor was Moab Khotsong where a decrease of R240 million was recognised while movement in 2020 is minimal. The environmental provision for PNG amounts to R1 267 million (2019: R994 million ) and is unfunded due to regulations in the operating country. 25 PROVISION FOR ENVIRONMENTAL REHABILITATION continued While the ultimate amount of rehabilitation costs to be incurred in the future is uncertain, the group has estimated that, based on current environmental and regulatory requirements, the total undiscounted cost for the operations, in the current monetary terms, is as follows: SA Rand Figures in million 2020 2019 Future net undiscounted obligation Ultimate estimated rehabilitation cost 4 600 4 139 Amounts invested in environmental trust funds (refer to note 16) (3 513 ) (3 273 ) Total future net undiscounted obligation 1 087 866 The group's mines are required to comply with the National Environmental Act's (NEMA) financial provision requirements, and are required to substantively review and align their financial provision in accordance with these regulations during the relevant transitional period, which was to expire in February 2020, but has now been extended to 19 June 2021. The group intends to finance the ultimate rehabilitation costs from the money invested in environmental trust funds as well as the proceeds on sale of assets and gold from plant clean-up at the time of mine closure. The group has guarantees in place, some cash-backed, relating to some of the environmental liabilities. Refer to notes 15 and 36 . PROVISION FOR SILICOSIS SETTLEMENT CRITICAL ACCOUNTING ESTIMATES AND JUDGEMENTS Significant judgement is applied in estimating the cost that will be required in future to settle any claims against certain of the group’s mines. The ultimate cost may differ from current estimates. The provision amount was based on estimates of number of potential claimants, levels of disease progression and take-up rates. These estimates were informed by historic information, published academic research and professional opinion. The key assumptions that were made in the determination of the provision amount include: • Silicosis prevalence rates; • Estimated settlement per claimant; • Benefit take-up rates; • Disease progression rates; and • Timing of cash flows. A discount rate of 7.6% ( 2019 : 8.5% ) ( 2018 : 8.5% ) was used, based on South African government bonds with similar terms to the obligation. There is uncertainty with regards to the rate at which potential claims would be reported as well as the benefit take-up rates. Refer to sensitivity analysis on the key assumptions below. Consolidated class action Harmony and certain of its subsidiaries (Harmony group), together with other mining companies, were named in a class action suit for silicosis and tuberculosis which was certified by the Johannesburg High Court in May 2016. On 26 July 2019, the Johannesburg High Court approved the R5.2 billion settlement of the silicosis and tuberculosis class action suit between the Occupational Lung Disease Gold Working Group (the Working Group) – representing Gold Fields, African Rainbow Minerals, Anglo American SA, AngloGold Ashanti, Harmony and Sibanye Stillwater – and lawyers representing affected mineworkers (settlement agreement). The mandatory three-month period, during which potential beneficiaries could opt out of the settlement agreement and the audit thereof was completed in December 2019. The Tshiamiso Trust will oversee the tracking and tracing of class members, process all submitted claims, including the undertaking of benefit medical examinations, and pay benefits to eligible claimants. A jointly controlled Special Purpose Vehicle has been set-up to act as an agent for the Working Group in relation to certain matters set out in the settlement agreement and trust deed. The Working Group has paid the legal costs of the claimants’ attorneys and other initial amounts as set out in the settlement agreement. On 31 January 2020, the Working Group commenced the payment of their quarterly administration and benefit contributions to the Tshiamiso Trust to enable the trustees to settle benefits of eligible claimants. Harmony has provided for the estimated cost of the settlement based on actuarial assessments. A portion of the provision has been transferred to current liabilities.The nominal amount for Harmony group is R1.14 billion . 26 PROVISION FOR SILICOSIS SETTLEMENT continued The following is a reconciliation of the total provision for the silicosis settlement: SA Rand Figures in million 2020 2019 Balance at beginning of year 942 925 Change in estimate 36 (62 ) Time value of money and inflation component 69 79 Payments to Tshiamso Trust and claimant attorneys (155 ) — Balance at end of year 892 942 Current portion of silicosis settlement provision 175 — Non-current portion of silicosis settlement provision 717 942 Sensitivity analysis The impact of a reasonable change in certain key assumptions would increase or decrease the provision amount by the following amounts: SA Rand Figures in million 2020 2019 Effect of an increase in the assumption: Change in benefit take-up rate 1 72 66 Change in silicosis prevalence 2 72 66 Change in disease progression rates 3 36 33 Effect of a decrease in the assumption: Change in benefit take-up rate 1 (72 ) (66 ) Change in silicosis prevalence 2 (72 ) (66 ) Change in disease progression rates 3 (36 ) (33 ) 1 Change in benefit take-up rate: the take-up rate does not affect the legal cost allocation, but a 10% change results in a proportionate change in the other values. 2 Change in the silicosis prevalence: the assumptions that will result in a change in the estimated number of cases are either a 10% change in the assumed labour number or a 10% change in the disease risk. 3 Change in disease progression rates: a 10% shorter/longer disease progression period was used. This assumption is not applicable to the dependant or TB classes. The above sensitivity analysis is based on a change in an assumption while holding all other assumptions constant. In practice, this is unlikely to occur, and changes in some of the assumptions may be correlated. A change in the settlement claim amount would result in a change in the provision amount on a Rand for Rand basis. The ultimate outcome of this matter remains uncertain, with the number of eligible potential claimants successfully submitting claims and receiving compensation being uncertain. The provision recorded in the financial statements is consequently subject to adjustment or reversal in the future.

PROVISION FOR SILICOSIS SETTLEMENT CRITICAL ACCOUNTING ESTIMATES AND JUDGEMENTS Significant judgement is applied in estimating the cost that will be required in future to settle any claims against certain of the group’s mines. The ultimate cost may differ from current estimates. The provision amount was based on estimates of number of potential claimants, levels of disease progression and take-up rates. These estimates were informed by historic information, published academic research and professional opinion. The key assumptions that were made in the determination of the provision amount include: • Silicosis prevalence rates; • Estimated settlement per claimant; • Benefit take-up rates; • Disease progression rates; and • Timing of cash flows. A discount rate of 7.6% ( 2019 : 8.5% ) ( 2018 : 8.5% ) was used, based on South African government bonds with similar terms to the obligation. There is uncertainty with regards to the rate at which potential claims would be reported as well as the benefit take-up rates. Refer to sensitivity analysis on the key assumptions below.

Retirement Benefit Obligation

Retirement Benefit Obligation	12 Months Ended
	Jun. 30, 2020
Employee Benefits [Abstract]
Retirement Benefit Obligation	RETIREMENT BENEFIT OBLIGATION ACCOUNTING POLICY The group provides medical cover to current employees and certain retirees through certain funds. The medical accounting costs for the defined benefit plan are assessed using the projected unit credit method. The health care obligation is measured at the present value of the estimated future cash outflows using government bond interest rates consistent with the terms and risks of the obligation. Actuarial gains and losses as a result of these valuations are recognised in other comprehensive income (OCI) at revaluation date. Actuarial gains and losses recognised in OCI will not be recycled to profit or loss. The future liability for current and retired employees and their dependants is accrued in full based on actuarial valuations obtained annually. 27 RETIREMENT BENEFIT OBLIGATION continued CRITICAL ACCOUNTING ESTIMATES AND JUDGEMENTS An updated actuarial valuation is carried out at the end of each financial year. Assumptions used to determine the liability include a discount rate of 11.2% , no increases in employer subsidies (in terms of the agreement), mortality rates according to the SA 1956/62 mortality table (SA “”a mf”” tables) (retirement age of 60 ) and a medical inflation rate of 8.5% ( 2019 : discount rate of 9.7% , retirement age of 60 and 7.8% inflation rate) (2018: discount rate of 9.8% , retirement age of 60 and 7.9% inflation rate). Management determined the discount rate by assessing South African government bonds with similar terms to the liability. The changes to the discount rate and medical inflation rate are similar to changes in interest and inflation rates in South Africa. (a) Pension and provident funds The group contributes to several pension and provident funds governed by the Pension Funds Act, 1956 for the employees of its South African subsidiaries. The pension funds are multi-employer defined contribution industry plans. The group’s liability is therefore limited to its monthly determined contributions. The provident funds are funded on a “monetary accumulative basis” with the member’s and employer’s contributions having been fixed in the constitution of the funds. The Australian group companies make contributions to each employee’s superannuation (pension) funds in accordance with the Superannuation Guarantee Scheme (SGS). The SGS is a Federal Government initiative enforced by law which compels employers to make regular payments to regulated funds providing for each employee on their retirement. The SGS were set at a minimum of 9.5% of gross salary and wages for the 2020 year ( 2019 : 9.5% ). The fund is a defined contribution plan. The PNG Superannuation Act 2002 requires a compulsory employer contribution of 8.4% ( 2019 : 8.4% ) into an approved superannuation (pension) fund if an employee is appointed for a period of three months or more. The approved superannuation funds are defined contribution plans. Substantially all the group’s employees are covered by the above mentioned retirement benefit plans. Funds contributed by the group for the 2020 financial year amounted to R842 million ( 2019 : R766 million ). (b) Post-retirement benefits other than pensions Harmony inherited a post-retirement medical benefit obligation, which existed at the time of the Freegold acquisition in 2002. The group also inherited various post-retirement medical benefit obligations with the acquisition of the Moab Khotsong operations in 2018. Given the insignificant values attributed to the Moab Khotsong obligations, the details have not been included in the discussion below. Except for the abovementioned employees, Harmony has no other post-retirement benefit obligation for the other group employees. The group’s obligation is to pay a subsidy of 2% for every completed year of employment up to a maximum of 50% of total medical aid contributions, commencing on date of retirement. Should the employee die, either in service or after retirement, this benefit will transfer to his/her dependants. The medical aid tariffs are based on the Bestmed medical scheme (Bestmed) options. The principal actuarial assumptions used to determine the present value of unfunded obligations are discussed above. In addition the following was also considered: • It is assumed that all Continuation and Widow Members (CAWMs) will remain on the current benefit option and income band. For employed members, post-employment contributions were assumed to be equal to the average payable for the current CAWMs membership; • It is assumed that not all employed members will remain employed until retirement therefore estimated resignation and ill-health retirement rates are also taken into account; • It is assumed that 90% of employed members will be married at retirement or earlier death and that wives are four years younger than their husbands. Through the post-employment medical plan, the group is exposed to a number of risks, the most significant of which are discussed below: • Change in bond yields: A decrease in the bond yields will increase the plan liability. • Inflation risk: The obligation is linked to inflation and higher inflation will lead to a higher liability. • Life expectancy: The obligation is to provide benefits for the life of the member, so increases in life expectancy will result in an increase in the plan’s liabilities. The liability is unfunded and will be settled out of cash and cash equivalents when it becomes due. The liability is based on an actuarial valuation conducted during the year ended 30 June 2020 , using the projected unit credit method.

The group expects to contribute approximately R11 million to the benefit plan in 2021 . The weighted average duration of the defined benefit obligation is 12.5 years . EMPLOYEE BENEFITS ACCOUNTING POLICY • Pension, provident and medical benefit plans are funded through monthly contributions. The group pays fixed contributions into a separate entity in terms of the defined contribution pension, provident and medical plans which are charged to the income statement in the year to which they relate. The group's liability is limited to its monthly determined contributions and it has no further liability, legal or constructive, if the fund does not hold sufficient assets to pay all employees the benefits relating to employee service in the current and prior periods. Refer to note 27 for details of the post-retirement medical benefit plan. • Termination benefits are payable when employment is terminated before the normal retirement date, or whenever an employee accepts voluntary redundancy in exchange for these benefits. The group recognises termination benefits at the earlier of the following dates: (a) when the group can no longer withdraw the offer of those benefits; and (b) when the entity recognises costs for a restructuring that is within the scope of IAS 37, Provisions, Contingent Liabilities and Contingent Assets , and involves the payment of termination benefits. In the case of an offer made to encourage voluntary redundancy, the termination benefits are measured based on the number of employees expected to accept the offer. Benefits falling due more than 12 months after balance sheet date are discounted to present value. 2020 2019 Number of permanent employees as at 30 June: South African operations 31 504 31 199 International operations 1 1 589 1 638 Total number of permanent employees 33 093 32 837 SA Rand Figures in million 2020 2019 Aggregate earnings The aggregate earnings of employees including executive directors were: Salaries and wages and other benefits (excluding share-based payments) 10 540 10 623 Retirement benefit costs 842 766 Medical aid contributions 276 259 Total aggregated earnings 2 11 658 11 648 1 The Wafi-Golpu joint operation's employees included in the total is 81 ( 2019 : 194 ). 2 These amounts have been included in cost of sales, corporate expenditure and capital expenditure.

Disclosure of leases [Abstract]
Disclosure of leases [text block]	LEASES ACCOUNTING POLICY The leases accounting policy is applicable from 1 July 2019. The group assesses the presence of a lease in a contract as at the commencement date of the agreement. Having determined that a contract contains a lease asset (and respective contractual cash obligations), Harmony recognises a right-of-use asset and lease liability. The group discloses expensed amounts for contracts assessed as variable leases, low value asset leases and short-term leases. The disclosed value of these expensed leases is either determined on a straight-line basis over the duration of the lease or on a systematic basis that fairly indicates the consumption of the lease contract. All expensed lease contracts are recognised in production costs, corporate, administration and other expenditure in the income statement. The lease liability is initially measured at the present value of the lease payments that are not paid at the commencement date, discounted by using the rate implicit in the lease. If this rate cannot be readily determined, the group uses its incremental borrowing rate. The group has applied the IFRS 16 portfolio approach in determining the discount rate for leases. As such a single discount rate has been used for contracts that share similar characteristics. The group has determined that a portfolio of contracts that are denominated in the same currency may use a single discount rate. This rate has been determined using various factors including in-country borrowings as well as other sources of finance. The nature of the right-of-use assets was also considered. Lease payments included in the measurement of the lease liability comprise: • Fixed lease payments (including in-substance fixed payments), less any lease incentives; • Variable lease payments that depend on an index or rate, initially measured using the index or rate at the commencement date; • The amount expected to be payable by the lessee under residual value guarantees; • The exercise price of purchase options, if the lessee is reasonably certain to exercise the options; and • Payments of penalties for terminating the lease, if the lease term reflects the exercise of an option to terminate the lease. The non-current and current portions of the lease liability is included in other non-current liabilities and trade and other payables in the balance sheet respectively. The lease liability is subsequently measured by increasing the carrying amount to reflect interest on the lease liability (using the effective interest method) and by reducing the carrying amount to reflect the lease payments made. The group remeasures the lease liability (and makes a corresponding adjustment to the related right-of-use asset) whenever: • The lease term has changed or there is a change in the assessment of exercise of a purchase option, in which case the lease liability is remeasured by discounting the revised lease payments using a revised discount rate; • The lease payments change due to changes in an index or rate or a change in expected payment under a guaranteed residual value, in which cases the lease liability is remeasured by discounting the revised lease payments using the initial discount rate (unless the lease payments change is due to a change in a floating interest rate, in which case a revised discount rate is used). • A lease contract is modified and the lease modification is not accounted for as a separate lease, in which case the lease liability is remeasured by discounting the revised lease payments using a revised discount rate. The right-of-use assets comprise the initial measurement of the corresponding lease liability, lease payments made at or before the commencement day, any initial direct costs and restoration costs as described below. They are subsequently measured at cost less accumulated depreciation and impairment losses. The lease term shall be determined as the non-cancellable period of a lease, together with: • Periods covered by an option to extend the lease if management is reasonably certain to make use of that option; and / or • Periods covered by an option to terminate the lease, if management is reasonably certain not to make use of that option. Whenever the group incurs an obligation for costs to dismantle and remove a leased asset, restore the site on which it is located or restore the underlying asset to the condition required by the terms and conditions of the lease, a provision is recognised and measured under IAS 37 Provisions, Contingent Liabilities and Contingent Assets . The costs are included in the related right-of-use asset, unless those costs are incurred to produce inventories. Right-of-use assets are depreciated over the shorter period of lease term and useful life of the underlying asset. If a lease transfers ownership of the underlying asset or the cost of the right-of-use asset reflects that the group expects to exercise a purchase option, the related right-of-use asset is depreciated over the useful life of the underlying asset. The depreciation starts at the commencement date of the lease. The right-of-use assets are presented in the property, plant and equipment line in the balance sheet. The group applies its existing accounting policy on impairment of non-financial assets to determine whether a right-of-use asset is impaired and accounts for any identified impairment loss accordingly. 28 LEASES continued CRITICAL ACCOUNTING ESTIMATES AND JUDGEMENTS Key judgements applied in determining the right-of-use assets and lease liability were: • Assessing whether an arrangement contains a lease: various factors are considered, including whether a service contract includes the implicit right to the majority of the economic benefit from assets used in providing the service; • Determining the lease term: management considers all facts and circumstances that create an economic incentive to exercise an extension option, or not exercise a termination option. Extension options (or periods after termination options) are only included in the lease term if the lease is reasonably certain to be extended (or not terminated). The assessment is reviewed if a significant event or a significant change in circumstances occurs which affects this assessment and that is within the control of the lessee. The company applies the considerations for short-term leases where leases are modified to extend the period by 12 months or less on expiry and these modifications are assessed on a standalone basis; and • Determining the discount rate: in determining the incremental borrowing rates, management considers the term of the lease, the nature of the asset being leased, in country borrowings as well as other sources of finance. The movement in the right-of-use assets is as follows: SA Rand Figures in million 2020 Balance at beginning of year — Impact of adopting IFRS 16 at 1 July 2019 81 Additions 106 Depreciation (45 ) Terminations (8 ) Translation 17 Balance at end of year 151 The non-current and current portions of the lease liability is included in other non-current liabilities and trade and other payables in the balance sheet respectively.

Variable lease payments made comprise 81% of the total lease payments made during the period. The majority of the variable lease payments made relate to the contracting of specialists for mining operations at Harmony's open pit mines and are determined on a per tonne or square metre basis.

Employee Benefits

Employee Benefits [Abstract]
Employee Benefits	RETIREMENT BENEFIT OBLIGATION ACCOUNTING POLICY The group provides medical cover to current employees and certain retirees through certain funds. The medical accounting costs for the defined benefit plan are assessed using the projected unit credit method. The health care obligation is measured at the present value of the estimated future cash outflows using government bond interest rates consistent with the terms and risks of the obligation. Actuarial gains and losses as a result of these valuations are recognised in other comprehensive income (OCI) at revaluation date. Actuarial gains and losses recognised in OCI will not be recycled to profit or loss. The future liability for current and retired employees and their dependants is accrued in full based on actuarial valuations obtained annually. 27 RETIREMENT BENEFIT OBLIGATION continued CRITICAL ACCOUNTING ESTIMATES AND JUDGEMENTS An updated actuarial valuation is carried out at the end of each financial year. Assumptions used to determine the liability include a discount rate of 11.2% , no increases in employer subsidies (in terms of the agreement), mortality rates according to the SA 1956/62 mortality table (SA “”a mf”” tables) (retirement age of 60 ) and a medical inflation rate of 8.5% ( 2019 : discount rate of 9.7% , retirement age of 60 and 7.8% inflation rate) (2018: discount rate of 9.8% , retirement age of 60 and 7.9% inflation rate). Management determined the discount rate by assessing South African government bonds with similar terms to the liability. The changes to the discount rate and medical inflation rate are similar to changes in interest and inflation rates in South Africa. (a) Pension and provident funds The group contributes to several pension and provident funds governed by the Pension Funds Act, 1956 for the employees of its South African subsidiaries. The pension funds are multi-employer defined contribution industry plans. The group’s liability is therefore limited to its monthly determined contributions. The provident funds are funded on a “monetary accumulative basis” with the member’s and employer’s contributions having been fixed in the constitution of the funds. The Australian group companies make contributions to each employee’s superannuation (pension) funds in accordance with the Superannuation Guarantee Scheme (SGS). The SGS is a Federal Government initiative enforced by law which compels employers to make regular payments to regulated funds providing for each employee on their retirement. The SGS were set at a minimum of 9.5% of gross salary and wages for the 2020 year ( 2019 : 9.5% ). The fund is a defined contribution plan. The PNG Superannuation Act 2002 requires a compulsory employer contribution of 8.4% ( 2019 : 8.4% ) into an approved superannuation (pension) fund if an employee is appointed for a period of three months or more. The approved superannuation funds are defined contribution plans. Substantially all the group’s employees are covered by the above mentioned retirement benefit plans. Funds contributed by the group for the 2020 financial year amounted to R842 million ( 2019 : R766 million ). (b) Post-retirement benefits other than pensions Harmony inherited a post-retirement medical benefit obligation, which existed at the time of the Freegold acquisition in 2002. The group also inherited various post-retirement medical benefit obligations with the acquisition of the Moab Khotsong operations in 2018. Given the insignificant values attributed to the Moab Khotsong obligations, the details have not been included in the discussion below. Except for the abovementioned employees, Harmony has no other post-retirement benefit obligation for the other group employees. The group’s obligation is to pay a subsidy of 2% for every completed year of employment up to a maximum of 50% of total medical aid contributions, commencing on date of retirement. Should the employee die, either in service or after retirement, this benefit will transfer to his/her dependants. The medical aid tariffs are based on the Bestmed medical scheme (Bestmed) options. The principal actuarial assumptions used to determine the present value of unfunded obligations are discussed above. In addition the following was also considered: • It is assumed that all Continuation and Widow Members (CAWMs) will remain on the current benefit option and income band. For employed members, post-employment contributions were assumed to be equal to the average payable for the current CAWMs membership; • It is assumed that not all employed members will remain employed until retirement therefore estimated resignation and ill-health retirement rates are also taken into account; • It is assumed that 90% of employed members will be married at retirement or earlier death and that wives are four years younger than their husbands. Through the post-employment medical plan, the group is exposed to a number of risks, the most significant of which are discussed below: • Change in bond yields: A decrease in the bond yields will increase the plan liability. • Inflation risk: The obligation is linked to inflation and higher inflation will lead to a higher liability. • Life expectancy: The obligation is to provide benefits for the life of the member, so increases in life expectancy will result in an increase in the plan’s liabilities. The liability is unfunded and will be settled out of cash and cash equivalents when it becomes due. The liability is based on an actuarial valuation conducted during the year ended 30 June 2020 , using the projected unit credit method. The next actuarial valuation will be performed on 30 June 2021 . 27 RETIREMENT BENEFIT OBLIGATION continued (b) Post-retirement benefits other than pensions continued SA Rand Figures in million 2020 2019 Present value of all unfunded obligations 193 201 Current employees 56 54 Retired employees 137 147 The movement in the retirement benefit obligation is as follows: Balance at beginning of year 201 186 Contributions paid (12 ) (12 ) Other expenses included in staff costs/current service cost 2 3 Finance costs 19 17 Net actuarial (gain)/loss recognised in other comprehensive income during the year (17 ) 7 Balance at end of year 193 201 The net actuarial gain for 2020 was mainly caused by an increased discount rate as well as a decline in members ( 2019 : net actuarial loss was mainly due to an increase in subsidy inflation).

In practice, this is unlikely to occur, and changes in some of the assumptions may be correlated. The analysis is performed on the same basis for 2019 . The group expects to contribute approximately R11 million to the benefit plan in 2021 . The weighted average duration of the defined benefit obligation is 12.5 years . EMPLOYEE BENEFITS ACCOUNTING POLICY • Pension, provident and medical benefit plans are funded through monthly contributions. The group pays fixed contributions into a separate entity in terms of the defined contribution pension, provident and medical plans which are charged to the income statement in the year to which they relate. The group's liability is limited to its monthly determined contributions and it has no further liability, legal or constructive, if the fund does not hold sufficient assets to pay all employees the benefits relating to employee service in the current and prior periods. Refer to note 27 for details of the post-retirement medical benefit plan. • Termination benefits are payable when employment is terminated before the normal retirement date, or whenever an employee accepts voluntary redundancy in exchange for these benefits. The group recognises termination benefits at the earlier of the following dates: (a) when the group can no longer withdraw the offer of those benefits; and (b) when the entity recognises costs for a restructuring that is within the scope of IAS 37, Provisions, Contingent Liabilities and Contingent Assets , and involves the payment of termination benefits. In the case of an offer made to encourage voluntary redundancy, the termination benefits are measured based on the number of employees expected to accept the offer. Benefits falling due more than 12 months after balance sheet date are discounted to present value. 2020 2019 Number of permanent employees as at 30 June: South African operations 31 504 31 199 International operations 1 1 589 1 638 Total number of permanent employees 33 093 32 837 SA Rand Figures in million 2020 2019 Aggregate earnings The aggregate earnings of employees including executive directors were: Salaries and wages and other benefits (excluding share-based payments) 10 540 10 623 Retirement benefit costs 842 766 Medical aid contributions 276 259 Total aggregated earnings 2 11 658 11 648 1 The Wafi-Golpu joint operation's employees included in the total is 81 ( 2019 : 194 ). 2 These amounts have been included in cost of sales, corporate expenditure and capital expenditure.

Share-based payment arrangements [Abstract]
Share-Based Payments	SHARE-BASED PAYMENTS ACCOUNTING POLICY The group operates the following employee share incentive plans where the group granted share options to certain employees in exchange for services received: • The 2006 equity-settled share-based payments plan; • The equity-settled Sisonke Employee Share Ownership Plan (ESOP) awarded in 2019; and • The equity-settled Management Deferred Share Plan (DSP) awarded during the 2020 financial year. Equity-settled share-based payments are measured at fair value that includes market performance conditions but excludes the impact of any service and non-market performance conditions of the equity instruments at the date of the grant. The share-based payments are expensed over the vesting period, based on the group's estimate of the shares that are expected to eventually vest. The group used an appropriate option pricing model in determining the fair value of the options granted. Non-market vesting conditions are included in assumptions about the number of options that are expected to vest. At each balance sheet date, the estimates of the number of options that are expected to become exercisable are revised. The impact of the revision of original estimates, if any, is recognised in the income statement, with a corresponding adjustment to equity. The proceeds received (if any) net of any directly attributable transaction costs are credited to share capital and premium when the options are exercised. CRITICAL ACCOUNTING ESTIMATES AND JUDGEMENTS The fair value of options granted under the 2006 plan was determined using a Monte Carlo valuation model. The significant inputs into the model are: vesting period, risk free interest rate, volatility, price on date of grant and dividend yield. There were no options granted under the 2006 plan in the current financial period. The fair value of the options granted under the Sisonke ESOP was based on the Harmony spot share price of R28.29 at grant date as there were no market conditions attached to the grant. The fair value of the options granted under the DSP was based on the Harmony spot share prices of between R45.89 and R56.87 at grant date as there was no market condition attached to the grant. EMPLOYEE SHARE-BASED PAYMENTS The objective of these schemes is to recognise the contributions of employees to the group's financial position and performance and to retain key employees. The total cost relating to employee share-based payments is made up as follows: SA Rand Figures in million 2020 2019 2006 share plan 83 197 Sisonke ESOP 73 33 Management DSP 30 — Total employee share-based payments 186 230 The directors are authorised to issue up to 60 011 669 ordinary shares to participants who have received awards in accordance with Harmony's employee share incentive schemes. Subsequent to the annual general meeting held on 1 December 2010, 40 573 097 shares have been issued in terms of the various share schemes. At 30 June 2020, 12 792 357 share option awards are outstanding in terms of the authorisation and relate to the 2006 share plan. In December 2018, the board approved the new Total Incentive Plan for management which includes deferred shares. The first allocations under the new plan occurred in October 2019. Our shareholders have authorised up to 25 000 000 shares of the issued share capital to be used for this plan. 34 SHARE-BASED PAYMENTS continued EMPLOYEE SHARE-BASED PAYMENTS continued Options granted under the 2006 share plan The 2006 share plan consists of share appreciation rights (SARs), performance shares (PS) and restricted shares (RS). The share plan is equity-settled. Award Vesting Performance criteria SARs SARs will vest in equal thirds in year three, four and five, subject to the performance conditions having been satisfied. The SARs will have an expiry date of six years from the grant date and the offer price equals the closing market prices of the underlying shares on the trading date immediately preceding the grant. 2013 to 2014 allocation: The group's headline earnings per share must have grown since the allocation date by more than the South African Consumer Price Index (CPI). PS The PS will vest after three years from the grant date, if and to the extent that the performance conditions have been satisfied. 2015 to 2017 allocation: • 50% of the number of rights awarded are linked to the total shareholder return of the group on an absolute basis. • 50% of the number of rights awarded are linked to the total shareholder return of the group as compared to that of the South African gold index. RS The RS will vest after three years from grant date. The participant is still employed within the group. Termination of employees' participation in the share plan is based on "no fault" and "fault" definitions. • Fault All unvested and unexercised SARs and all PS and RS not yet vested are lapsed and cancelled. • No fault Accelerated vesting occurs and all unvested and unexercised share options are settled in accordance with the rules of the plan. Executive management is encouraged to retain performance shares when they vest and a minimum shareholding requirement has been introduced to achieve this. This shareholding is meant to align shareholder and executive objectives to grow total shareholder return.

The shares were issued to the Harmony ESOP Trust (the Trust) on 15 January 2019 which is also the date on which the required service period of three years commenced. Each beneficiary under the scheme was awarded 225 Participation Units (PU). The Sisonke ESOP is equity-settled. Award Vesting Performance criteria PU* The PU will vest after three years from the date on which the service period commenced The participant is still employed within the group * The term Participation Units means the vested rights of a beneficiary to an equal number of Harmony shares held by the Trust.

The total incentive for each management-level employee is determined every year through a balanced scorecard calculation. The balanced scorecard result includes a number of key short- and long-term company performance measures (to be measured over trailing three- and one-year periods). The measures are reviewed and defined annually with appropriate weightings. A portion of the total incentive is paid immediately in cash and the balance is settled by means of deferred shares, which will vest at a rate of 20% per annum over the following five years for the executive managers and prescribed officers, and one-third per annum over the following three years for qualifying management.

The transaction closed on 25 June 2013, following the fulfilment of the last condition precedent. In terms of the agreements Phoenix was transferred to a newly incorporated subsidiary; 'PhoenixCo' which subsequently changed its name to Tswelopele Beneficiation Operation (TBO). The awards to the BEE partners have been accounted for as in-substance options as the BEE partners will only share in the upside, and not the downside of their equity interest in TBO until the date the financing provided by Harmony is fully repaid. On this date the options will be exercised and a non-controlling interest in TBO will be recognised. The award of the options to the BEE partners is accounted for by the group as an equity-settled share-based payment arrangement. The in-substance options carry no vesting conditions and the fair value of the options of R23 million was expensed on the grant date, 25 June 2013. On 31 December 2019, the loans were settled in full and the option was exercised . The portion of the BEE shareholders' interest in TBO was measured at the net asset value of negative R5 million and reclassified to non-controlling interest on this date. On initial recognition, TBO's negative net asset value of R5 million consists of accumulated profits of R222 million and a historic debit common control reserve of R250 million . The total comprehensive income attributable to the BEE shareholders allocated to non-controlling interest for the six months ended 30 June 2020 was R12 million and includes a portion of the unrealised loss from the hedges in other reserves. A dividend was declared by TBO on 5 March 2020 and the portion to non-controlling interests amounted to R3 million .

Refer to note 15 . CONTINGENT LIABILITIES CRITICAL ACCOUNTING ESTIMATES AND JUDGEMENTS Contingencies will only realise when one or more future events occur or fail to occur. The exercise of significant judgement and estimates of the outcome of future events are required during the assessment of the impact of such contingencies. Litigation and other judicial proceedings as a rule raise difficult and complex legal issues and are subject to uncertainties and complexities including, but not limited to, the facts and circumstances of each particular case, issues regarding the jurisdiction in which the suit is brought and differences in applicable law. Upon resolution of any pending legal matter, the group may be forced to incur charges in excess of the presently established provisions and related insurance coverage. It is possible that the financial position, results of operations or cash flows of the group could be materially affected by the outcome of the litigation. The following contingent liabilities have been identified: (a) On 1 December 2008, Harmony issued 3 364 675 Harmony shares to Rio Tinto Limited (Rio Tinto) for the purchase of Rio Tinto’s rights to the royalty agreement entered into prior to our acquisition of the Wafi deposits in PNG. The shares were valued at R242 million on the transaction date. An additional US$10 million in cash will be payable when the decision to mine is made. Of this amount, Harmony is responsible for paying the first US$6 million , with the balance of US$4 million being borne equally by the joint operators. 36 COMMITMENTS AND CONTINGENCIES continued CONTINGENT LIABILITIES continued (b) The group may have a potential exposure to rehabilitate groundwater and radiation that may exist where the group has and/or continues to operate. The group has initiated analytical assessments to identify, quantify and mitigate impacts if and when (or as and where) they arise. Numerous scientific, technical and legal studies are underway to assist in determining the magnitude of the contamination and to find sustainable remediation solutions. The group has instituted processes to reduce future potential seepage and it has been demonstrated that Monitored Natural Attenuation (MNA) by the existing environment will contribute to improvement in some instances. Water treatment facilities were successfully implemented at Doornkop, Tshepong Operations and Kusasalethu. These facilities are now assisting in reducing our dependency on state supplied potable water and will be key in managing any post closure decant should it arise. In terms of Free State operations, Harmony has taken the initiative to develop a comprehensive regional closure plan in addition to updating the regional water balance, which will ensure that there is sufficient water for our organic growth initiatives. The geohydrological studies confirm that there is no risk of decant in Welkom. Should the group determine that any part of these contingencies require them being recorded and accounted for as liabilities, that is where they become estimable and probable, it could have a material impact on the financial statements of the group. (c) Due to the interconnected nature of mining operations in South Africa, any proposed solution for potential flooding and potential decant risk posed by deep groundwater needs to be a combined one, supported by all the mines located in these goldfields. As a result, the Department of Mineral Resources and Energy and affected mining companies require the development of a regional mine closure strategy. Harmony operations have conducted a number of specialist studies and the risk of surface decant due to rising groundwater levels has been obviated at the entire Free State region and Kalgold. In addition, the decant from the KOSH groundwater system tied with our Moab Khotsong operation has been managed through an appropriate groundwater closure plan and sufficient provision has been set aside for this. Therefore, there is no contingency arising from these operations. Additional studies have been commissioned at Doornkop and Kusasalethu. Studies that have been conducted indicate that there is no risk of decant from Doornkop and Kusasalethu, but it is recommended that confirmatory studies be completed. In view of the limitation of current information for accurate estimation of a liability, no reliable estimate can be made for these operations. (d) The individual Harmony mining operations have applied for the respective National Water Act, Section 21 Water Use Licenses (WUL) to the Department of Water and Sanitation (DWS). The respective Water Use License Applications (WULA’s) have subsequently not yet been approved by DWS. Two WUL have been issued by DWS for Kalgold and Kusasalethu (amendment currently being drafted for both operations), with neither licence having any material impact to the operation. The remaining WULA’s have not yet been approved by DWS. The WUL conditions for the respective operations are subsequently not yet known and the subsequent potential water resource impact liability as part of the mine rehabilitation and closure process (to which DWS is an important participant and decision maker) is uncertain. The existing WUL for Moab Khotsong, which was recently acquired by Harmony, has already been approved by the DWS. The transferral of the licence and its conditions to Harmony is currently being processed. All operations continue to operate legally and responsibly. (e) In terms of the sale agreements entered into with Rand Uranium, Harmony retained financial exposure relating to environmental disturbances and degradation caused by it before the effective date, in excess of R75 million of potential claims. Rand Uranium is therefore liable for all claims up to R75 million and retains legal liability. The likelihood of potential claims cannot be determined presently and no provision for any liability has been made in the financial statements.

Financial Risk Management

Financial Risk Management	12 Months Ended

Financial Instruments [Abstract]
Financial Risk Management	FINANCIAL RISK MANAGEMENT The effects of COVID-19 and other macro developments have increased financial risks such as exchange rate, interest rate and commodity price volatility, while also impacting on liquidity and credit risk. Management has put various measures in place to mitigate and/or manage the risks and continues to monitor the situation closely. Refer to note 37 for additional detail. Balance sheet protection and liquidity measures The company committed to several measures to protect its balance sheet in the face of the global pandemic. These included cash preservation, the suspension of exploration and major capital projects and declaration of force majeure on select supplier agreements. Specific measures aimed at ensuring liquidity were undertaken, such as restructuring a portion of the derivatives maturing during April and May 2020 into the first three quarters of the new financial year, as well as drawing down on the Rand and US Dollar facilities. During June 2020, the company's lenders agreed to relax certain requirements for compliance with debt covenants until December 2020. Refer to note 30 for disclosures on debt covenants. Market impact Exchange rates Due to the impact of the COVID-19 pandemic, the Rand has weakened significantly from the beginning of the 2020 calendar year, which was at levels of around R 14.00 /US$1, to its weakest level at the beginning of April 2020 of R 19.05 . The Rand strengthened through May and June and the Rand closed at R 17.32 on 30 June 2020. The Rand started weakening against the Australian dollar in April 2020 and closed at R 11.96 /A$1 on 30 June 2020, a 21% decrease in value. These movements in the currencies expose the group's operations to foreign currency gains and losses on foreign-denominated receivables and liabilities, including derivatives, and also impact the group’s translation of its international operating results and net assets into its Rand presentation currency, which resulted in a foreign exchange translation movement of R1.2 billion in other comprehensive income. The most significant impact was on the increase in the Rand gold price Harmony received on its gold sales, of which R2.3 billion of the increase in revenue can be attributed to the weakening of the Rand. This was calculated by multiplying actual kilograms sold in the 2020 financial year by the variance in the average exchange rates year on year and 2019's average US$ gold price received. 4 . COVID-19 IMPACT continued FINANCIAL RISK MANAGEMENT continued Market impact continued Commodity prices Gold prices have rallied to an all-time high following the global economic fallout of COVID-19 and ongoing geopolitical uncertainty supporting its safe haven status with investors. The price of gold in US$ terms increased significantly over the period, closing at US$1 781/oz on 30 June 2020. This is a 26% increase from the closing price of US$1 410 /oz on 30 June 2019. The average spot gold price received (that is, excluding the impact of hedging gains or losses) for the 2020 financial year was 21% higher at US$1 529 /oz than in 2019 ( US$1 263 /oz), contributing approximately R5.2 billion to the increase in revenue year on year. This was calculated by multiplying actual kilograms sold in the 2020 financial year by the variance in the average US$ gold price year on year and 2020's average R/US$ exchange rate. Interest rates The US Federal Reserve lowered interest rates several times during the year, the majority unrelated to the COVID-19 pandemic. The rate cuts of 25 basis points were made on each of the following dates, 31 July 2019, 18 September 2019, 30 October 2019 and 3 March 2020. At an unscheduled meeting on 15 March 2020, an additional cut of 100 basis points was announced, reducing the rate to a range of between 0% and 0.25% as a benchmark for most interest rates. The South African Reserve Bank (SARB) announced similar decreases in the repo rate during the year. The adjustment in the repo rate then affects the prime lending rate at which commercial banks lend money. The repo rate was cut by 25 basis points at the July 2019 and January 2020 SARB meetings respectively. Following the interest rate cut by the Federal Reserve in March 2020, the SARB also announced a 100 basis point cut. At a special unscheduled meeting in April 2020, the SARB cut the rate by a further 100 basis points. During the scheduled May 2020 meeting, another 50 basis point cut was decided on, bringing the prime lending rate to 7.25% and the total cuts for the 2020 financial year to 300 basis points. These decreases have had a favourable impact on the cost of debt, as the debt facilities are linked to variable rates, US LIBOR and JIBAR specifically. However, the finance cost on the US-denominated debt is impacted by the movement in the Rand/US$ exchange rate. FINANCIAL RISK MANAGEMENT The group's operating activities expose it to a variety of financial risks: market risk (including commodity price risk, currency risk, cash flow interest rate risk and other price risk), credit risk and liquidity risk. The group may use derivative financial instruments to hedge certain risk exposures. The group's financial assets and liabilities are classified as set out below: Figures in million (SA Rand) Debt instruments at amortised cost Equity instruments designated at fair value through OCI Derivatives designated as cash flow hedges Derivatives at fair value through profit or loss Debt instruments at fair value through profit or loss Financial liabilities at amortised cost At 30 June 2020 Financial assets Restricted cash 169 — — — — — Restricted investments 2 698 — — — 837 — Other non-current assets 5 77 — — 306 — Non-current derivative financial instruments — — 15 35 — — - Rand gold hedging contracts — — 10 — — — - US$ gold hedging contracts — — 5 — — — - US$ silver contracts — — — 5 — — - Foreign exchange contracts — — — 30 — — - Rand gold derivative contracts — — — — — — Current derivative financial instruments — — 12 6 — — - Rand gold hedging contracts — — 9 — — — - US$ gold hedging contracts — — 3 — — — - US$ silver contracts — — — 6 — — Trade and other receivables 804 — — — — — Cash and cash equivalents 6 357 — — — — — Financial liabilities Non-current derivative financial instruments — — 813 66 — — - Rand gold hedging contracts — — 717 — — — - US$ gold hedging contracts — — 96 — — — - US$ silver contracts — — — 1 — — - Foreign exchange contracts — — — 65 — — Current derivative financial instruments — — 3 169 955 — — - Rand gold hedging contracts — — 2 909 — — — - US$ gold hedging contracts 260 — — — - US$ silver contracts — — — 3 — — - Foreign exchange contracts — — — 695 — — - Rand gold derivative contracts — — — 257 — — Borrowings — — — — — 7 718 Other non-current liabilities — — — — — 96 Trade and other payables — — — — — 970 37 FINANCIAL RISK MANAGEMENT continued Figures in million (SA Rand) Debt instruments at amortised cost Equity instruments designated at fair value through OCI Derivatives designated as cash flow hedges Derivatives at fair value through profit or loss Debt instruments at fair value through profit or loss Financial liabilities at amortised cost At 30 June 2019 Financial assets Restricted cash 136 — — — — — Restricted investments 2 045 — — — 1 256 — Other non-current assets 3 59 — — 271 — Non-current derivative financial instruments — — 24 173 — — - Rand gold hedging contracts — — 23 — — — - US$ gold hedging contracts — — 1 — — — - Foreign exchange contracts — — — 173 — — Current derivative financial instruments — — 26 283 — — - Rand gold hedging contracts — — 22 — — — - US$ gold hedging contracts — — 4 — — — - US$ silver contracts — — — — — — - Foreign exchange contracts — — — 283 — — Trade and other receivables 627 — — — — — Cash and cash equivalents 993 — — — — — Financial liabilities Non-current derivative financial instruments — — 172 — — — - Rand gold hedging contracts — — 158 — — — - US$ gold hedging contracts — — 14 — — — Current derivative financial instruments — — 205 65 — — - Rand gold hedging contracts — — 164 — — — - US$ gold hedging contracts — — 41 — — — - US$ silver contracts — — — 2 — — - Foreign exchange contracts — — — 2 — — - Rand gold derivative contracts — — — 61 — — Borrowings — — — — — 5 915 Other non-current liabilities — — — — — 2 Trade and other payables — — — — — 930 Risk management is carried out by a central treasury department (Group treasury) under policies approved by the board of directors. Group treasury identifies, evaluates and hedges certain selected financial risks in close cooperation with the group's operating units. The audit and risk committee and the board provides written principles for overall risk management, as well as written policies covering specific areas, such as commodity price risk, foreign exchange risk, interest rate risk, credit risk, use of derivative financial instruments and non-derivative financial instruments, and the investment of excess liquidity. Since March 2020, the COVID-19 pandemic has impacted on various aspects of Harmony's operating environment. Where relevant, reference is made to certain impacts in the discussions below, however a detailed discussion thereof is included in note 4 . 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 US dollar (US$). Foreign exchange risk arises when future commercial transactions or recognised financial assets or liabilities are denominated in a currency that is not the entity’s functional currency. Harmony’s revenues are sensitive to the R/US$ exchange rate as all revenues are generated by commodity sales denominated in US$. Harmony may enter into hedging transactions to reduce this risk. The limit currently set by the board is 25% of the group's foreign exchange risk exposure for a period of 24 months . Refer to note 18 and the fair value determination for financial assets and liabilities section below for details of the contracts. The audit and risk committee review the details of the programme quarterly. The Rand has weakened significantly during the 2020 year, especially during the June 2020 quarter as a result of the COVID-19 pandemic, closing at R 17.32 /US$1 on 30 June 2020 (2019: R 14.13 /US$1).This negatively impacted on the valuation of contracts that matured during the quarter and that were outstanding at 30 June 2020. However Harmony continues to enjoy favourable foreign exchange pricing on the uncovered portion of its exposure, while simultaneously locking-in the current higher prices as part of its derivative programme. The group is exposed to foreign exchange risk arising from borrowings and cash denominated in a currency other than the functional currency of that entity (refer to note 2.2 for details on the group's functional currencies). These exposures are mainly to the US$. The Rand's levels impacted negatively on the translation of the US$ debt facilities at 30 June 2020. Refer to note 30 for further detail. Translation of the international net assets was impacted by a similar weakening of the Rand against the Australian dollar from R9.91 /A$1 at 30 June 2019 to R 11.96 /A$1. A gain of R1.2 billion has been recognised in other comprehensive income. The group has reviewed its foreign currency exposure on financial assets and financial liabilities and has identified the following sensitivities for a 10% change in the exchange rate that would affect profit or loss. Management considers a range between 10% and 20% to be a reasonable change given the volatility in the market. The analysis has been performed on the same basis for 2019.

Harmony entered into Rand gold and US dollar forward gold sale contracts to manage the variability in cash flows from the group’s production, in order to create cash certainty and protect the group against lower commodity prices. The general limit for gold hedging currently set by the board is 20% for a 24 -month period. The limit set by the board is 50% of silver exposure over a 24 -month period. Management continues to top up these programmes as and when opportunities arise to lock in attractive margins for the business, but are not required to maintain hedging at these levels. The audit and risk committee review the details of the programme quarterly. The exposure to the variability in the price of gold is managed by entering into gold forward sales contracts for a portion of the group's production. A portion of the production of the South African operations is linked to Rand gold forward contracts and US$ gold forward contracts were entered into for the production from Hidden Valley. The exposure to the variability in the price of silver for Hidden Valley is managed by entering into US$/silver zero cost collars. These contracts have not been designated as hedging instruments for hedge accounting and the gains and losses are accounted for in the income statement. Refer to note 18 and the fair value determination for financial assets and liabilities section below for further detail on these contracts. Due to the COVID-19 pandemic, markets experienced extreme volatility in the last four months of the 2020 financial year. As a result of the heightened risk globally, the price of gold in US$ terms increased significantly over the period with the spot price increasing by 26% year on year. This increase, together with the weakening of the Rand discussed above, had a negative impact on the contracts that matured during the June 2020 quarter as well as those that were outstanding at 30 June 2020. However Harmony continues to enjoy favourable commodity and foreign exchange pricing on the unhedged portion of its exposure, while simultaneously locking-in the current higher prices as part of its hedging programme. The group has reviewed its exposure to commodity linked instruments and has identified the following sensitivities for a 10% change in the commodity price specified per contract that would affect other comprehensive income and profit or loss. Management considers a range between 10% and 20% to be a reasonable change given the recent volatility in the market. The analysis has been performed on the same basis for 2019. SA Rand Figures in million 2020 2019 Sensitivity analysis Rand gold derivatives Profit or loss Increase by 10% (91 ) (76 ) Decrease by 10% 102 79 Other comprehensive income Increase by 10% (1 279 ) (1 162 ) Decrease by 10% 1 433 1 174 US$ gold derivatives Profit or loss Increase by 10% — (20 ) Decrease by 10% — 20 Other comprehensive income Increase by 10% (258 ) (110 ) Decrease by 10% 279 113 US$ silver derivatives Profit or loss Increase by 10% (40 ) — Decrease by 10% 41 4 37 FINANCIAL RISK MANAGEMENT continued MARKET RISK continued Other price risk The group is exposed to the risk of fluctuations in the fair value of fair value through profit or loss financial assets as a result of changes in market prices (other than changes in interest rates and foreign currencies). Harmony generally does not use any derivative instruments to manage this risk. Sensitivity analysis Certain of the restricted investments are linked to the Top 40 Index on the JSE. A 10% increase in the Top 40 index at the reporting date, with all other variables held constant, would have increased profit or loss by R79 million ( 2019 : R76 million ); an equal change in the opposite direction would have decreased profit or loss by R42 million ( 2019 : R17 million ). Interest rate risk The group's interest rate risk arises mainly from long-term borrowings. The group has variable interest rate borrowings. Variable rate borrowings expose the group to cash flow interest rate risk. The group has not entered into interest rate swap agreements as this is a risk that management is prepared to take as the risk is deemed to be low. The audit and risk committee reviews the exposures quarterly. The interest rate cuts by both the US Federal Reserve and the SARB had a favourable impact on the cost of debt during the year. This was offset by the weakening of the Rand on the cost for the US$ facilities, as well as the increased debt levels, especially in the last quarter, as discussed in Capital Risk Management below. Interest rate risk arising from long-term borrowings is offset by cash, restricted cash and restricted investments held at variable rates. A change of 100 basis points in interest rates at the reporting date would have increased/(decreased) profit or loss before tax by the amounts shown below. This analysis assumes that all other variables remain constant. The analysis has been performed on the same basis for 2019. SA Rand Figures in million 2020 2019 Sensitivity analysis - borrowings (finance costs) Increase by 100 basis points (77 ) (59 ) Decrease by 100 basis points 77 59 Sensitivity analysis - financial assets (interest received) Increase by 100 basis points (a) 58 44 Decrease by 100 basis points (a) (58 ) (44 ) (a) The computed sensitivity analysis permissibly excludes cash received on 30 June 2020 as a result of the the equity raise on 24 June 2020 in note 12 . 37 FINANCIAL RISK MANAGEMENT continued CREDIT RISK Credit risk is the risk that a counterparty may default or not meet its obligations in a timely manner. Financial instruments which are subject to credit risk are restricted cash, restricted investments, derivative financial instruments and cash and cash equivalents, as well as trade and other receivables (excluding non-financial instruments). Assessment of credit risk In assessing the creditworthiness of local institutions, management uses the national scale long-term ratings. The credit risk arising from restricted cash, cash and cash equivalents, restricted investments and derivative financial assets is managed by ensuring amounts are only invested with financial institutions of good credit quality based on external credit ratings. The group has policies that limit the amount of credit exposure to any one financial institution. The audit and risk committee reviews the exposure on a quarterly basis. Exposure to credit risk on trade and other receivables is monitored on a regular basis by management. Predominantly as a result of the global COVID-19 pandemic, on 27 March 2020, Moody's Investor Service downgraded the South African government's long-term foreign currency and local currency issuer ratings to Ba1 from Baa3, which is a sub-investment grade rating. The country’s sovereign downgrade prompted a re-rating of the five major banks’ international credit ratings as the local banks cannot have a rating higher than the country's sovereign rating. Furthermore, on 31 March 2020, Fitch Ratings (Fitch) downgraded South Africa’s five major banks citing an adverse impact (driven by the virus) on the banks' operating environment and key financial metrics, notwithstanding any uncertainty on the full economic and financial market implications. Taking the above events into consideration, the effects of COVID-19 have resulted in the credit ratings of financial institutions dropping by a notch, however, the national scale investment grade rating of these banks is still high, between A+ and AA, and in line with the group's credit risk policy. An assessment of the expected credit losses for the financial assets measured at amortised costs at 30 June 2020 resulted in an immaterial amount for each instrument, in line with the assessment performed in 2019 (refer to Expected credit loss assessment below for further detail). The downgrade therefore had an immaterial effect on these financial instruments. Management will continue to review the underlying strength of the South African economy as well as the creditworthiness of the financial institutions during this uncertain time and make any changes deemed necessary to safeguard the assets and reduce the credit risk. The group’s maximum exposure to credit risk is represented by the carrying amount of all financial assets determined to be exposed to credit risk, amounting to R11 244 million as at 30 June 2020 ( 2019 : R5 837 million ). The Social Trust Fund of R22 million ( 2019 : R28 million ) has been invested in unit trust investments comprising shares in listed companies. 37 FINANCIAL RISK MANAGEMENT continued CREDIT RISK continued Assessment of credit risk continued Financial institutions' credit rating by exposure (Source: Fitch Ratings and Global Credit Ratings) SA Rand Figures in million 2020 2019 Cash and cash equivalents AA — 671 AA- 6 357 322 6 357 993 Restricted cash AA — 109 AA- 169 27 169 136 Restricted investments (environmental trusts) AA — 3 273 AA- 3 513 — 3 513 3 273 Derivative financial assets AA 10 393 AA- 41 69 A+ 15 44 66 506 Expected credit loss assessment The group recognises loss allowances for expected credit losses (ECLs) on financial assets measured at amortised cost. The group's debt instruments at amortised cost consist of cash and cash equivalents, restricted cash, a portion of restricted investments and trade and other receivables. The assessment of ECLs for the different debt instruments is discussed below: Cash and cash equivalents The cash and cash equivalents are held with banks and financial institutions which are rated AA- (see above). The ECL on cash and cash equivalents has been determined using the simplification that allows the group to assume that the credit risk on financial instruments determined to have low credit risk at the reporting date, has not increased significantly since initial recognition of the financial instrument. The ECL was estimated with reference to a probability of default model using external credit ratings in determining the default risk of counterparties. The ECL was determined to be immaterial. Restricted cash and investments The restricted cash and investments relate largely to the environmental trust funds. These funds are held with banks and financial institutions which are rated AA- (see above). Impairment of these investments has been determined using the simplification that allows the group to assume that the credit risk on financial instruments determined to have low credit risk at the reporting date, has not increased significantly since initial recognition of the financial instrument. The group considers that its restricted investments and cash have low credit risk based on the external credit ratings of the counterparties with which the funds are deposited with. The ECL was estimated with reference to a probability of default model using external credit ratings in determining the default risk of counterparties. Concentration of credit risk on restricted cash and investments is considered minimal due to the group’s investment risk management and counterparty exposure risk management policies. The ECL was determined to be immaterial. 37 FINANCIAL RISK MANAGEMENT continued CREDIT RISK continued Expected credit loss assessment continued Trade and other receivables The group’s exposure to credit risk arising from trade receivables (metals) and other trade receivables is influenced mainly by the individual characteristics of each customer. Trade receivables result largely from the sale of gold and are fully performing. Exposure to credit risk on receivables from gold sales is limited through payment terms of two to three days after recognition of revenue for gold sales. The majority of other receivables comprise of a limited number of individually significant customers. The group determines the ECL on trade receivables and individually significant other receivable balances with reference to a probability of default model using external credit ratings in determining the default risk of counterparties. The external credit ratings used range between A+ to AA. The ECL was determined to be immaterial. Loss allowances on individually insignificant other trade receivables has been determined using the simplified ECL approach using a provision matrix and reflects the short-term maturities of the exposures and past experienced credit judgement. Refer to note 19 for details on the amount of the loss allowance recognised and the stratification of trade and other receivables for purposes of the assessment. LIQUIDITY RISK Prudent liquidity risk management implies maintaining sufficient cash and marketable securities, and the availability of funding through an adequate amount of committed credit facilities. In the ordinary course of business, the group receives cash from its operations and is required to fund working capital and capital expenditure requirements. Management prepares cash flow forecasts weekly and ensures that surplus funds are invested in a manner to achieve market-related returns and to provide sufficient liquidity at the minimum risk. The group maintains and refinances committed credit facilities as medium-term forecasts require. The audit and risk committee reviews the updated forecasts quarterly. The group is able to actively source financing at competitive rates. Where necessary, funds will be drawn from its revolving credit facilities (refer to note 30 ). The following are the undiscounted contractual maturities of financial liabilities (including principal and interest payments assuming the closing R/US$ exchange rate and interest rate at year end): SA Rand Figures in million Current More than 1 year 2020 Other non-current liabilities — 101 Trade and other payables (excluding non-financial liabilities) 969 — Derivative financial liabilities 4 238 962 Borrowings Due between 0 to six months 257 — Due between six to 12 months 399 — Due between one to two years — 779 Due between two to four years — 7 536 5 863 9 378 37 FINANCIAL RISK MANAGEMENT continued LIQUIDITY RISK continued SA Rand Figures in million Current More than 1 year 2019 Other non-current liabilities — 2 Trade and other payables (excluding non-financial liabilities) 930 — Derivative financial liabilities 280 194 Borrowings Due between 0 to six months 242 — Due between six to 12 months 241 — Due between one to two years — 4 578 Due between two to four years — 1 624 1 693 6 398 CAPITAL RISK MANAGEMENT The primary objective of managing the group’s capital is to ensure that there is sufficient capital available to support the funding requirements of the group, in a way that optimises the cost of capital and matches the current strategic business plan. The group manages and makes adjustments to the capital structure, which consists of debt and equity, as and when borrowings mature or when funding is required. This may take the form of raising equity, market or bank debt or hybrids thereof. In doing so, the group ensures it stays within the debt covenants agreed with lenders. The group may also sell assets to reduce debt or schedule projects to manage the capital structure. On 30 June 2020 the group received R3 466 million , through an equity raise, in order to fund the acquisition of AGA's remaining South African assets (refer to note 12 ). This capital injection has in part attributed to the increase in cash reserves and the consequential decline in the net debt balance. Harmony drew down additional funds from its debt facilities to sustain ordinary operations and resist any detrimental impacts of COVID-19, resulting in an increase in borrowings (refer to note 30 ). The levels in Rand terms were also impacted by the translation of US dollar denominated borrowings following the weakening of the Rand. It is the group's objective to adhere to a conservative approach to debt and maintain low levels of gearing. Net debt is as follows: SA Rand Figures in million 2020 2019 Cash and cash equivalents 6 357 993 Borrowings (7 718 ) (5 915 ) Net debt (1 361 ) (4 922 ) There were no changes to the group's approach to capital management during the year. FAIR VALUE DETERMINATION FOR FINANCIAL ASSETS AND LIABILITIES The fair value levels of hierarchy are as follows: Level 1: Quoted prices (unadjusted) in active markets; Level 2: Inputs other than quoted prices included within level 1 that are observable for the asset, either directly (that is, as prices) or indirectly (that is, derived from other prices); Level 3: Inputs for the asset that are not based on observable market data (that is, unobservable inputs). The following table sets out the group’s assets and liabilities measured at fair value by level within the fair value hierarchy: SA Rand Figures in million At 30 June 2020 At 30 June 2019 Level 2 Level 3 Level 2 Level 3 Fair value through other comprehensive income Other non-current assets (a) — 77 — 59 Fair value through profit or loss Restricted investments (b) 837 — 1 256 — Derivative financial assets (c) 68 — 506 — Derivative financial liabilities (c) (5 003 ) — (422 ) — Loan to ARM BBEE Trust (d) — 306 — 271 (a) The increase in level 3 fair value measurement relates to the equity investment in Rand Mutual Assurance previously carried at cost. The fair value of the investment was estimated with reference to an independent valuation. A combination of the "Embedded Valuation" and "Net Asset Value" techniques were applied to revalue the investment as at 30 June 2020. In evaluating the group's share of the business, common practice marketability and minority discounts as well as additional specific risk discounts were applied. (b) The majority of the balance is directly derived from the Top 40 index on the JSE, and is discounted at market interest rate. This relates to equity-linked deposits in the group's environmental rehabilitation trust funds. The balance of the environmental trust funds are carried at amortised cost and therefore not disclosed here. (c) The mark-to market remeasurement of the derivative contracts was determined as follows: • Foreign exchange contracts comprise of zero cost collars and FECs: The zero cost collars were valued using a Black-Scholes valuation technique derived from spot Rand/US$ exchange rate inputs, implied volatilities on the Rand/US$ exchange rate, Rand/US$ inter-bank interest rates and discounted at market interest rate (zero-coupon interest rate curve). The value of the FECs is derived from the forward Rand/US$ exchange rate and discounted at market interest rate (zero-coupon interest rate curve). • Rand gold contracts (forward sale contracts): spot Rand/US$ exchange rate, Rand and dollar interest rates (forward points), spot US$ gold price, differential between the US interest rate and gold lease interest rate which is discounted at market interest rate. • US$ gold contracts (forward sale contracts): spot US$ gold price, differential between the US interest rate and gold lease interest rate and discounted at market interest rate. • Silver contracts (zero cost collars): a Black-Scholes valuation technique, derived from spot US$ silver price, strike price, implied volatilities, time to maturity and interest rates and discounted at market interest rate. (d) The increase in level 3 fair value measurement relates to the ARM BBEE loan that was carried at amortised cost prior to 1 July 2018. Refer to note 17 . The fair value was calculated using a discounted cash flow model taking into account projected interest payments and the projected share price for African Rainbow Minerals Limited (ARM) on the expected repayment date. A 10% change in the discount rate of 9.8% would not cause a material change to the fair value of the loan. The fair value of the loan balance is limited to the sum of the capital amounts plus cumulative interest not paid, being R316 million . The carrying values (less any impairment allowance) of short-term financial instruments are ass

Segment Report

Segment Report	12 Months Ended

Disclosure of entity's operating segments [Abstract]
Segment Report	SEGMENT REPORT ACCOUNTING POLICY Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision-maker (CODM). The chief operating decision-maker has been identified as the CEO's office. The group has one main economic product, being gold. In order to determine operating and reportable segments, management reviewed various factors, including geographical location as well as managerial structure. It was determined that an operating segment consists of a shaft or a group of shafts or open pit mine managed by a single general manager and management team. After applying the qualitative and quantitative thresholds from IFRS 8, Operating Segments , the reportable segments were determined as: Tshepong Operations, Moab Khotsong, Bambanani, Joel, Doornkop, Target 1, Kusasalethu, Masimong, Unisel and Hidden Valley. All other operating segments have been grouped together under all other surface operations. The CODM has been identified as the CEO's office consisting of the chief executive officer, financial director, executive director: new business development, executive director: corporate affairs, chief operating officer: new business development, corporate strategy and projects, chief executive officer: South-east Asia and chief operating officer: South Africa operations. During 2020, the executive: business development was added to the CEO's office, following the appointment of a new financial director. When assessing profitability, the CODM considers the revenue and production costs of each segment. The net of these amounts is the production profit or loss. Therefore, production profit has been disclosed in the segment report as the measure of profit or loss. The CODM also considers capital expenditure, gold production and tonnes milled when assessing the overall economic sustainability of each segment. The CODM, however, does not consider depreciation or impairment and therefore these amounts have not been disclosed in the segment report. Segment assets consist of mining assets and mining assets under construction included under property, plant and equipment which can be attributed to the segment.

Disclosure of entity's operating segments [Abstract]
Reconciliation of Segment Information to Consolidated Income Statements and Balance Sheets	SEGMENT REPORT ACCOUNTING POLICY Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision-maker (CODM). The chief operating decision-maker has been identified as the CEO's office. The group has one main economic product, being gold. In order to determine operating and reportable segments, management reviewed various factors, including geographical location as well as managerial structure. It was determined that an operating segment consists of a shaft or a group of shafts or open pit mine managed by a single general manager and management team. After applying the qualitative and quantitative thresholds from IFRS 8, Operating Segments , the reportable segments were determined as: Tshepong Operations, Moab Khotsong, Bambanani, Joel, Doornkop, Target 1, Kusasalethu, Masimong, Unisel and Hidden Valley. All other operating segments have been grouped together under all other surface operations. The CODM has been identified as the CEO's office consisting of the chief executive officer, financial director, executive director: new business development, executive director: corporate affairs, chief operating officer: new business development, corporate strategy and projects, chief executive officer: South-east Asia and chief operating officer: South Africa operations. During 2020, the executive: business development was added to the CEO's office, following the appointment of a new financial director. When assessing profitability, the CODM considers the revenue and production costs of each segment. The net of these amounts is the production profit or loss. Therefore, production profit has been disclosed in the segment report as the measure of profit or loss. The CODM also considers capital expenditure, gold production and tonnes milled when assessing the overall economic sustainability of each segment. The CODM, however, does not consider depreciation or impairment and therefore these amounts have not been disclosed in the segment report. Segment assets consist of mining assets and mining assets under construction included under property, plant and equipment which can be attributed to the segment. Current and non-current group assets that are not allocated at a segment level form part of the reconciliation to total assets. A reconciliation of the segment totals to the group financial statements has been included in note 40 .

Accounting Policies, Changes In Accounting Estimates And Errors [Abstract]
Basis of preparation	BASIS OF PREPARATION The principal accounting policies applied in the preparation of the consolidated financial statements have been consistently applied in all years presented except for the changes as described under "Recent accounting developments" below. The consolidated financial statements have been prepared in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board (IASB) and IFRS Interpretations Committee (IFRIC) Interpretations (collectively IFRS). The consolidated financial statements have been prepared on a going concern basis. The consolidated financial statements have been prepared to the nearest million and rounding may cause differences.
Statement of IFRS compliance	The consolidated financial statements have been prepared in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board (IASB) and IFRS Interpretations Committee (IFRIC) Interpretations (collectively IFRS).
New standards, amendments to standards and interpretations to existing standards adopted by the group	New standards, amendments to standards and interpretations to existing standards adopted by the group During the financial year, the following new standards, amendments to standards and interpretations to existing standards were adopted by the group. No other standards and amendments to standards that became effective during the 2020 year had a material impact on the consolidated financial statements. Impact of the adoption of IFRS 16 Leases Scope of IFRS 16 IFRS 16 replaces the previous accounting standard on leases, IAS 17 Leases and related Interpretations. The new standard introduces a single lease accounting model and requires a lessee to capitalise most leases with certain exemptions. A lessee is required to recognise a right-of-use asset representing its right to use the underlying leased asset and a lease liability representing its obligation to make lease payments. Transition The group has elected to apply IFRS 16 utilising the modified retrospective approach, under which the cumulative effect of adopting the new standard is recognised as an adjustment to the opening balance of retained earnings at 1 July 2019 with no restatement of comparative information. The cumulative effect of adopting the standard had no impact on opening retained earnings and resulted in the recognition of right-of-use assets, lease liabilities and the resultant deferred tax. The group has reassessed all contracts in determining the lease population. Refer to note 28 for details on the amount of right-of-use assets and lease liabilities recognised as well as the incremental borrowing rates used. Transition options • The group has elected to recognise the right-of-use assets at an amount equal to the lease liability at 1 July 2019 together with the ability to set off deferred tax assets and liabilities resulting from the leased assets and liabilities. The lease liabilities were measured at the present value of the remaining lease payments at 1 July 2019 and discounted using the relevant incremental borrowing rate; and • The accounting for operating leases with a remaining lease term of less than 12 months as at date of adoption have been classified as short-term leases and have not been recorded on the balance sheet. 2 ACCOUNTING POLICIES continued RECENT ACCOUNTING DEVELOPMENTS continued New standards, amendments to standards and interpretations to existing standards adopted by the group continued Impact of the adoption of IFRS 16 Leases continued Practical expedients applied • The low value lease exemption - the group has elected to take the low value exemption with a value of R50 000 for the individual leased asset value and also applied its accounting policy on capitalisation of assets based on IAS 1 materiality assessment; • The short-term lease exemption - leases with a duration of less than a year will be expensed in the income statement on a straight-line basis ; • Use of hindsight, such as in determining the lease term if the contract contains options to extend or terminate the lease where appropriate; • Non-lease components - the group has applied the practical expedient not to separate non-lease components from lease components, and instead account for each lease component and any associated non-lease components as a single lease component for the classes of underlying asset where it is appropriate to do so; and • Exclusion of initial direct costs for the measurement of the right-of-use asset at the date of initial application. Accounting policy The leases accounting policy is applicable from 1 July 2019. Refer to note 28 for the policy. IFRS 16 Leases (Amendment) On 1 June 2020, the IASB issued COVID-19-Related Rent Concessions, which amended IFRS 16 Leases.The amendment permits lessees, as a practical expedient, not to assess whether particular rent concessions occurring as a direct consequence of the COVID-19 pandemic are lease modifications and instead to account for those rent concessions as if they are not lease modifications. The amendment does not affect lessors. To provide the practical expedient when needed most, the IASB enabled immediate application of the amendment in any financial statements—interim or annual—not authorised for issue at the date the amendment was issued. The amendments did not have a material impact on the group. IAS 19 Employee Benefits (Amendment) The amendments require an entity to use the updated assumptions from a remeasurement of net defined benefit liability or asset resulting from a plan amendment, curtailment or settlement to determine current service cost and net interest for the remainder of the reporting period after the change to the plan. The amendments apply for annual periods beginning on or after 1 January 2019. The amendments did not have a material impact on the group. IAS 23 Borrowing Costs (Amendment) The amendments clarify that if any specific borrowing remains outstanding after the related asset is ready for its intended use or sale, that borrowing becomes part of the funds that an entity borrows generally when calculating the capitalisation rate on general borrowings.The amendments apply for annual periods beginning on or after 1 January 2019. The amendments did not have a material impact on the group. IAS 28 Investments in Associates and Joint Ventures (Amendment) The amendments clarify that an entity applies IFRS 9 to long-term interests in an associate and joint venture that form part of the net investment in the associate or joint venture but to which the equity method is not applied. The amendments apply for annual periods beginning on or after 1 January 2019. The amendments did not have a material impact on the group. IFRIC 23 Uncertainty over Income Tax Treatments The interpretation specifies how an entity should reflect the effects of uncertainties in accounting for income taxes and is effective for annual periods beginning on or after 1 January 2019. IFRIC 23 specifically clarifies how to incorporate this uncertainty into the measurement of tax as reported in the consolidated financial statements. The interpretation does not introduce any new disclosures but reinforces the need to comply with existing disclosure requirements about judgements made, assumptions and other estimates used and the potential impact of uncertainties that are not reflected. The interpretation did not have a material impact on the group.
New standards, amendments to standards and interpretations to existing standards that are not yet effective and have not been early adopted	New standards, amendments to standards and interpretations to existing standards that are not yet effective and have not been early adopted At the date of authorisation of these financial statements, the standards, amendments to standards and interpretations listed below were in issue but not yet effective. These new standards and interpretations have not been early adopted by the group and the group plans on adopting these standards, amendments to standards and interpretations on the dates when they become effective. IFRS 3 Business Combinations (Amendment) These amendments are effective for annual periods beginning on or after 1 January 2020 and make it easier for companies to decide whether activities and assets they acquire are a business or merely a group of assets. The amendments: • Confirm that a business must include inputs and a process, and clarified that: (i) the process must be substantive and (ii) the inputs and process must together significantly contribute to creating outputs; • Narrow the definitions of a business by focusing the definition of outputs on goods and services provided to customers and other income from ordinary activities, rather than on providing dividends or other economic benefits directly to investors or lowering costs; and • Add a test that makes it easier to conclude that a company has acquired a group of assets, rather than a business, if the value of the assets acquired is substantially all concentrated in a single asset or group of similar assets . All acquisitions going forward will be assessed using these amendments. Refer to note 12 . The amendments are not expected to have a material impact on the group. IFRS 7 Financial Instrument: Disclosures and IFRS 9 Financial Instruments (Amendment) The IASB issued an amendment to IFRS 9, IAS 39 and IFRS 7 insofar as they are affected by the Interest Rate Benchmark Reform and uncertainty during the reform period. The amendment addresses only the following hedge accounting requirements that are based on a forward-looking analysis: • The highly probable requirement; • Prospective assessments; and • Separately identifiable risk components. The amendments also require companies to provide additional information to investors about their hedging relationships which are directly affected by these uncertainties. Other than these specific amendments, the hedge accounting requirements would be unchanged. This amendment is effective for annual periods beginning on or after 1 January 2020. The amendments are not expected to have a material impact on the group. IFRS 7 Financial Instrument: Disclosures and IFRS 9 Financial Instruments (Amendment) The IASB has published 'Interest Rate Benchmark Reform - Phase 2 (Amendments to IFRS 9, IAS 39, IFRS 7, IFRS 4 and IFRS 16)' with amendments that address issues that might affect financial reporting during the reform of an interest rate benchmark, including the effects of changes to contractual cash flows or hedging relationships arising from the replacement of an interest rate benchmark with an alternative benchmark rate (replacement issues). The amendments are effective for annual periods beginning on or after 1 January 2021, with earlier application permitted. Harmony is still assessing the impact of this amendment. IFRS 9 Financial Instruments (Amendment) The amendment to IFRS 9 clarifies the fees a company includes when assessing whether the terms of a new or modified financial liability are substantially different from the terms of the original financial liability. This amendment is effective for annual periods beginning on or after 1 January 2022. The amendment is not expected to have a material impact on the group. IAS 1 Presentation of Financial Statements (Amendment) The IASB issued amendments to IAS 1 Presentation of Financial Statements to clarify its requirements for the presentation of liabilities in the statement of financial position. The amendments are effective from annual reporting periods beginning on or after 1 January 2023. The amendments are not expected to have a material impact on the group. IAS 1 Presentation of Financial Statements and IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors (Amendment) The amendments, effective for annual periods beginning on or after 1 January 2020, clarify and align the definition of "material" and provide guidance to help improve consistency in the application of materiality whenever it is used in IFRS Standards. 2 ACCOUNTING POLICIES continued RECENT ACCOUNTING DEVELOPMENTS continued New standards, amendments to standards and interpretations to existing standards that are not yet effective and have not been early adopted continued IAS 16 Property, Plant and Equipment (Amendment) The IASB issued Property, Plant and Equipment—Proceeds before Intended Use, which prohibit a company from deducting from the cost of property, plant and equipment amounts received from selling items produced while the company is preparing the asset for its intended use. Instead, a company will recognise such sales proceeds and related cost in profit or loss. This amendment is effective for annual periods beginning on or after 1 January 2022. Management is currently assessing the impact this would have on the group. IAS 37 Provisions, Contingent Liabilities and Contingent Assets (Amendment) The IASB issued Onerous Contracts–Cost of Fulfilling a Contract, which specifies which costs an entity includes in determining the cost of fulfilling a contract for the purpose of assessing whether the contract is onerous. This amendment is effective for annual periods beginning on or after 1 January 2022. The amendment is not expected to have a material impact on the group.
Measurement basis	The financial statements have been prepared under the historical cost convention except for certain financial assets and financial liabilities which are measured at fair value through profit or loss or other comprehensive income - refer to note 37 .
Consolidation	Consolidation The group recognises that control is the single basis for consolidation for all types of entities in accordance with IFRS 10 – Consolidated Financial Statements. The consolidated financial information includes the financial statements of the company, its subsidiaries, interest in associates and joint arrangements and structured entities. Where the group has no control over an entity, that entity is not consolidated. Control The group, regardless of the nature of its involvement with an entity, shall determine whether it is a parent by assessing whether it controls the investee. The group controls an entity when it is exposed, or has rights, to variable returns from its involvement with the entity and has the ability to affect those returns through its power to direct the activities of the entity. (i) 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 up until when that control ceases. Intercompany transactions, balances and unrealised gains on transactions between group companies are eliminated. Unrealised losses are also eliminated. Accounting policies of subsidiaries have been changed to ensure consistency with the policies adopted by the group. The group uses the acquisition method of accounting to account for business combinations. The consideration transferred for the acquisition of an acquiree is the fair value of the assets transferred, liabilities incurred 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. Acquisition-related costs are expensed as incurred. Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are measured initially at their fair values at the acquisition date. On an acquisition-by-acquisition basis, the group recognises any non-controlling interests in the acquiree either at fair value or at the non-controlling interest’s proportionate share of the acquiree’s net assets. The excess of the sum of the consideration transferred, the amount of any non-controlling interest in the acquiree and the acquisition-date fair value of any previously held equity interest in the acquiree over the fair value of the group’s share of the identifiable net assets acquired is recorded as goodwill. If this is less than the fair value of the net assets of the subsidiary acquired, in the case of a bargain purchase, the difference is recognised directly in the income statement below operating profit or loss. 2 ACCOUNTING POLICIES continued GROUP ACCOUNTING POLICIES continued 2.1 Consolidation continued (ii) Associates Associates are entities in which the group has significant influence, but not control, over operational and financial policies. This may be when there is a shareholding of between 20% and 50% of the voting rights or when significant influence can be otherwise demonstrated, for example where the group has the right of representation on the board of directors, or other governing body, of the entity. Investments in associates are accounted for by using the equity method of accounting, and are initially recognised at cost. The group’s investment in associates includes goodwill identified on acquisition. Cumulative post-acquisition movements are adjusted against the carrying amount of the investment. The group’s share of the associates’ post-acquisition profits or losses is recognised in the income statement, and its share of post acquisition movement in reserves is recognised in other reserves. When the group’s share of losses in an associate equals or exceeds its interest in the associate, the group does not recognise further losses, unless it has incurred obligations or made payments on behalf of the associate. The carrying value of an associate is reviewed on a regular basis and, if impairment in the carrying value has occurred, it is written off in the period in which such impairment is identified. Accounting policies of associates have been reviewed to ensure consistency with the policies adopted by the group. (iii) Joint arrangements Joint arrangements are arrangements of which two or more parties have joint control and are contractually bound. The joint arrangement can either be a joint operation or a joint venture. A joint operation is a joint arrangement whereby the parties that have joint control of the arrangement and have the right to the assets, and obligations for the liabilities, relating to the arrangement. These parties are called joint operators. A joint venture is a joint arrangement where the parties that have joint control of the arrangement have rights to the net assets of the arrangement. Those parties are called joint venturers. For interest in joint operations, the group includes its share of the joint operations' individual income and expenses, assets and liabilities and cash flows on a line-by-line basis with similar items in the group’s financial statements. Where an additional interest in a joint operation is acquired, the principles of IFRS 3 are applied to account for the transaction. The group recognises the portion of gains or losses on the sale of assets by the group to the joint operation that is attributable to the other joint operators. The group does not recognise its share of profits or losses from the joint operation that results from the purchase of assets by the group from the joint operation until it resells the assets to an independent party. However, if a loss on the transaction provides evidence of a reduction in the net realisable value of current assets or an impairment loss, the loss is recognised immediately. The group recognises its interest in a joint venture as an investment and accounts for it using the equity accounting method. (iv) Structured entities A structured entity is an entity that has been designed so that voting or similar rights are not the dominant factor in deciding who controls the entity, such as when any voting rights relate to administrative tasks only and the relevant activities are directed by means of contractual arrangements. The accounting treatment for a structured entity will fall into one of the aforementioned categories (i to iii) depending on whether the group has control over that structured entity.
Consolidation, Subsidiaries	(i) 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 up until when that control ceases. Intercompany transactions, balances and unrealised gains on transactions between group companies are eliminated. Unrealised losses are also eliminated. Accounting policies of subsidiaries have been changed to ensure consistency with the policies adopted by the group. The group uses the acquisition method of accounting to account for business combinations. The consideration transferred for the acquisition of an acquiree is the fair value of the assets transferred, liabilities incurred 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. Acquisition-related costs are expensed as incurred. Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are measured initially at their fair values at the acquisition date. On an acquisition-by-acquisition basis, the group recognises any non-controlling interests in the acquiree either at fair value or at the non-controlling interest’s proportionate share of the acquiree’s net assets. The excess of the sum of the consideration transferred, the amount of any non-controlling interest in the acquiree and the acquisition-date fair value of any previously held equity interest in the acquiree over the fair value of the group’s share of the identifiable net assets acquired is recorded as goodwill. If this is less than the fair value of the net assets of the subsidiary acquired, in the case of a bargain purchase, the difference is recognised directly in the income statement below operating profit or loss.
Business combinations	The group uses the acquisition method of accounting to account for business combinations. The consideration transferred for the acquisition of an acquiree is the fair value of the assets transferred, liabilities incurred 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. Acquisition-related costs are expensed as incurred. Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are measured initially at their fair values at the acquisition date. On an acquisition-by-acquisition basis, the group recognises any non-controlling interests in the acquiree either at fair value or at the non-controlling interest’s proportionate share of the acquiree’s net assets. The excess of the sum of the consideration transferred, the amount of any non-controlling interest in the acquiree and the acquisition-date fair value of any previously held equity interest in the acquiree over the fair value of the group’s share of the identifiable net assets acquired is recorded as goodwill. If this is less than the fair value of the net assets of the subsidiary acquired, in the case of a bargain purchase, the difference is recognised directly in the income statement below operating profit or loss.
Consolidation, Associates	2 ACCOUNTING POLICIES continued GROUP ACCOUNTING POLICIES continued 2.1 Consolidation continued (ii) Associates Associates are entities in which the group has significant influence, but not control, over operational and financial policies. This may be when there is a shareholding of between 20% and 50% of the voting rights or when significant influence can be otherwise demonstrated, for example where the group has the right of representation on the board of directors, or other governing body, of the entity. Investments in associates are accounted for by using the equity method of accounting, and are initially recognised at cost. The group’s investment in associates includes goodwill identified on acquisition. Cumulative post-acquisition movements are adjusted against the carrying amount of the investment. The group’s share of the associates’ post-acquisition profits or losses is recognised in the income statement, and its share of post acquisition movement in reserves is recognised in other reserves. When the group’s share of losses in an associate equals or exceeds its interest in the associate, the group does not recognise further losses, unless it has incurred obligations or made payments on behalf of the associate. The carrying value of an associate is reviewed on a regular basis and, if impairment in the carrying value has occurred, it is written off in the period in which such impairment is identified. Accounting policies of associates have been reviewed to ensure consistency with the policies adopted by the group.
Consolidation, Joint arrangements	(iii) Joint arrangements Joint arrangements are arrangements of which two or more parties have joint control and are contractually bound. The joint arrangement can either be a joint operation or a joint venture. A joint operation is a joint arrangement whereby the parties that have joint control of the arrangement and have the right to the assets, and obligations for the liabilities, relating to the arrangement. These parties are called joint operators. A joint venture is a joint arrangement where the parties that have joint control of the arrangement have rights to the net assets of the arrangement. Those parties are called joint venturers. For interest in joint operations, the group includes its share of the joint operations' individual income and expenses, assets and liabilities and cash flows on a line-by-line basis with similar items in the group’s financial statements. Where an additional interest in a joint operation is acquired, the principles of IFRS 3 are applied to account for the transaction. The group recognises the portion of gains or losses on the sale of assets by the group to the joint operation that is attributable to the other joint operators. The group does not recognise its share of profits or losses from the joint operation that results from the purchase of assets by the group from the joint operation until it resells the assets to an independent party. However, if a loss on the transaction provides evidence of a reduction in the net realisable value of current assets or an impairment loss, the loss is recognised immediately. The group recognises its interest in a joint venture as an investment and accounts for it using the equity accounting method.
Consolidation, Structured entities	(iv) Structured entities A structured entity is an entity that has been designed so that voting or similar rights are not the dominant factor in deciding who controls the entity, such as when any voting rights relate to administrative tasks only and the relevant activities are directed by means of contractual arrangements. The accounting treatment for a structured entity will fall into one of the aforementioned categories (i to iii) depending on whether the group has control over that structured entity.
Foreign currency translation	Foreign currency translation (i) Functional and presentation currency Items included in the financial statements of each of the group’s entities are measured using the currency of the primary economic environment in which the entity operates (the functional currency). The consolidated financial statements are presented in South African Rand, which is the group’s presentation currency. References to “A$” refers to Australian currency, “R” to South African currency, “$” or “US$” to United States currency and “K” or “kina” to Papua New Guinean currency. (ii) Transactions and balances Foreign exchange gains and losses resulting from the settlement of foreign currency transactions and from the translation to year-end exchange rates of monetary assets and liabilities denominated in foreign currencies are recognised in the income statement. This includes the gains and losses on the translation of the US$-denominated facilities. Gains and losses recognised in the income statement are included in the determination of other operating expenses. 2 ACCOUNTING POLICIES continued GROUP ACCOUNTING POLICIES continued 2.2 Foreign currency translation continued (iii) Group companies The results and financial position of all group entities (none of which has the currency of a hyperinflationary economy) that have a functional currency different from the presentation currency are translated into the presentation currency as follows: • Assets and liabilities for each balance sheet presented are translated at the closing rate at the date of that balance sheet while equity items are translated at historic rates; • Income and expenses for each income statement are translated at average exchange rates (the rate on the date of the transaction is used if the average is not a reasonable rate for the translation of the transaction); • All resulting exchange differences are recognised as a separate component of other comprehensive income. On consolidation, exchange differences arising from the translation of the net investment in foreign operations, and of borrowings and other currency instruments designated as hedges of such investments, are taken to other comprehensive income. When a foreign operation is sold or control is otherwise lost, exchange differences that were recorded in other comprehensive income are recognised in profit or loss in the period of the disposal or change in control. Goodwill and fair value adjustments arising on the acquisition of a foreign operation are treated as assets and liabilities of the foreign entity and translated at the closing rate.
Functional and presentation currency	(i) Functional and presentation currency Items included in the financial statements of each of the group’s entities are measured using the currency of the primary economic environment in which the entity operates (the functional currency). The consolidated financial statements are presented in South African Rand, which is the group’s presentation currency. References to “A$” refers to Australian currency, “R” to South African currency, “$” or “US$” to United States currency and “K” or “kina” to Papua New Guinean currency.
Derivatives and hedging activities	Derivatives and hedging activities Derivatives are initially recognised at fair value on the date a derivative contract is entered into and are subsequently remeasured to their fair value at the end of each reporting period. The accounting for subsequent changes in fair value depends on whether the derivative is designated as a hedging instrument, and if so, the nature of the item being hedged. The difference between the fair value of the derivative at initial recognition and expected forward transaction price is deferred and recognised as a day one gain or loss. The day one gain or loss is amortised over the derivative contract period and recognised in profit or loss in gains/losses on derivatives. The full fair value of a derivative is classified as a non-current asset or liability when the remaining maturity is more than 12 months; it is classified as a current asset or liability when the remaining maturity is less than 12 months . (i) Cash flow hedge The group designates certain derivatives as hedges of a particular risk associated with the cash flows of highly probable forecast transactions (cash flow hedges). At inception of the hedge relationship, the group documents the economic relationship between hedging instruments and hedged items including whether changes in the cash flows of the hedging instruments are expected to offset changes in the cash flows of hedged items. The group documents its risk management objective and strategy for undertaking its hedge transactions. The effective portion of changes in the fair value of derivatives that are designated and qualify as cash flow hedges is recognised in other comprehensive income and accumulated in reserves in equity. The gain or loss relating to the ineffective portion is recognised immediately in profit or loss within gains/losses on derivatives. Amounts accumulated in equity are reclassified to profit or loss in the periods when the forecast sale that is hedged takes place and affects profit or loss. The gain or loss relating to the effective portion of the Rand and US$ gold forward sales contracts is recognised in profit or loss within revenue. When a hedging instrument expires or is sold or terminated, or when a hedge no longer meets the criteria for hedge accounting, any cumulative gain or loss existing in equity at that time remains in equity and is recognised when the forecast transaction that was hedged is ultimately recognised in profit or loss. When a forecast transaction is no longer expected to occur, the cumulative gain or loss that was reported in equity is immediately reclassified to profit or loss. (ii) Derivatives not designated for hedge accounting purposes Certain derivative instruments do not qualify for hedge accounting. Changes in the fair value as well as gains and losses on expiry, disposal or termination of any derivative instrument that does not qualify for hedge accounting are recognised immediately in profit or loss and are included in gains/losses on derivatives.
Exploration expenditure	ACCOUNTING POLICIES continued GROUP ACCOUNTING POLICIES continued 2.4 Exploration expenditure The group has elected to expense all exploration and evaluation expenditures until it is concluded that the project is technically feasible and commercially viable, and that future economic benefits are therefore probable. The information used to make that determination depends on the level of exploration as well as the degree of confidence in the ore body as set out below. Exploration and evaluation expenditure on greenfield sites, being those where the group does not have any mineral deposits which are already being mined or developed, is expensed as incurred until the technical and commercial viability of the project has been demonstrated usually through the completion of a final feasibility study. However, in certain instances, the technical and commercial viability of the deposit may be demonstrated at an earlier stage, for example where an extended feasibility study is conducted and the underlying feasibility study in respect of specific components of the mineral deposit has advanced to such a stage that significant commercially viable reserves has been established, and the other criteria for the recognition of an asset have been met. At this point the expenditure is capitalised as mine development cost to the extent that future economic benefits are expected. Exploration and evaluation expenditure on brownfield sites, being those adjacent to mineral deposits which are already being mined or developed, is expensed as incurred until the group is able to demonstrate that future economic benefits are probable through the completion of a feasibility study, after which the expenditure is capitalised as mine development cost to the extent that future economic benefits are expected. A ‘feasibility study’ consists of a comprehensive study of the viability of a mineral project that has advanced to a stage where the mining method has been established, and which, if an effective method of mineral processing has been determined, includes a financial analysis based on reasonable assumptions of technical, engineering, operating economic factors and the evaluation of other relevant factors. The feasibility study, when combined with existing knowledge of the mineral property that is adjacent to mineral deposits that are already being mined or developed, allows the group to conclude that the project is technically feasible and commercially viable. Exploration and evaluation expenditure relating to extensions of mineral deposits which are already being mined or developed, including expenditure on the definition of mineralisation of such mineral deposits, is capitalised as a mine development cost following the completion of an economic evaluation equivalent to a feasibility study. This economic evaluation is distinguished from a feasibility study in that some of the information that would normally be determined in a feasibility study is instead obtained from the existing mine or development. This information, when combined with existing knowledge of the mineral property already being mined or developed, allows the directors to conclude that the project is technically feasible and commercially viable.
Impairment of non-financial assets	Impairment of non-financial assets Assets that have an indefinite useful life are not subject to amortisation or depreciation and are tested annually for impairment or when there is an indication of impairment. Assets that are subject to amortisation are reviewed annually on 30 June for impairment or whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. An impairment loss is recognised in the income statement for the amount by which the asset’s carrying amount exceeds its recoverable amount. The recoverable amount is the higher of an asset’s fair value less costs to sell and value in use. For the purposes of assessing impairment, assets are grouped at the lowest levels for which there are separately identifiable cash flows (cash generating unit or CGU). Each operating shaft, along with allocated common assets such as plants and administrative offices, is considered to be a cash generating unit as each shaft is largely independent from the cash flows of other shafts and assets belonging to the group. Fair value less cost to sell is generally determined by using discounted estimated after-tax future cash flows. Future cash flows are estimated based on quantities of recoverable minerals, expected commodity prices (considering current and historical prices, price trends and related factors), production levels and cash costs of production, all based on life-of-mine (LoM) plans. Future cash flows are discounted to their present value using a post-tax discount rate that reflects current market assessments of the time value of money and risk specific to the asset. Refer to note 13 for detail. The term “recoverable minerals” refers to the estimated amount of gold that will be obtained from reserves and resources and all related exploration stage mineral interests (except for other mine-related exploration potential and greenfields exploration potential discussed separately below) after taking into account losses during ore processing and treatment. Estimates of recoverable minerals from such related exploration stage mineral interests will be risk adjusted based on management’s relative confidence in such materials. In estimating future cash flows, assets are grouped at the lowest level for which there are identifiable cash flows that are largely independent of cash flows from other asset groups. With the exception of other mine-related exploration potential and greenfields exploration potential, estimates of future undiscounted cash flows are included on an area of interest basis, which generally represents an individual operating mine, even if the mines are included in a larger mine complex. 2 ACCOUNTING POLICIES continued GROUP ACCOUNTING POLICIES continued 2.5 Impairment of non-financial assets continued In the case of mineral interests associated with other mine-related exploration potential and greenfields exploration potential, cash flows and fair values are individually evaluated based primarily on recent exploration results and recent transactions involving sales of similar properties, if any. Assumptions underlying future cash flow estimates are subject to significant risks and uncertainties. Impairment losses on goodwill are recognised immediately in the income statement and are not reversed. The impairment testing is performed annually on 30 June or when events or changes in circumstances indicate that it may be impaired. Non-financial assets other than goodwill that suffered an impairment are reviewed annually for possible reversal of the impairment at 30 June. Reversal of impairments is also considered when there is objective evidence to indicate that the asset is no longer impaired. Where an impairment subsequently reverses, the carrying amount of the asset or CGU is increased to the revised estimate of its recoverable amount, but not higher than the carrying value that would have been determined had no impairment been recognised in prior years.
Operating profit	Operating profit The group defines operating profit as the profit earned from the normal core mining operations. In reporting operating profit in the income statement, transactions for capital transactions involving subsidiaries, joint arrangements and associates are excluded from operating profit as these are not considered to be part of the mining operations of the Harmony group. Any gains or losses on capital transactions are presented below the operating profit line.
Revenue	ACCOUNTING POLICY Revenue from metal sales include the sale of gold, silver and uranium. Revenue from metal sales is recognised when the group satisfies its performance obligations under its contract with the customer, by transferring such metals to the customer's control. Transfer of control is generally determined to be when the risk and title to the metals passes to the customer. Revenue is measured based on the consideration specified in the contract with the customer and is driven by the quoted market prices of the metals. The effective portion of gains or losses on the derivatives designated as cash flow hedging items (forecast sales transactions) are recognised in revenue when the forecast sales transactions occur. See the accounting policy for derivatives and hedging activities in note 2 .
Investment income	ACCOUNTING POLICY Interest income is recognised on the effective interest method, taking into account the principal outstanding and the effective rate over the period to maturity, when it is determined that such income will accrue to the group. Dividend income is recognised when the shareholder's right to receive payment is established. This is recognised at the last date of registration. Cash flows from interest and dividends received are classified under operating activities in the cash flow statement.
Finance costs	ACCOUNTING POLICY Borrowing costs are capitalised to the extent that they are directly attributable to the acquisition and construction of qualifying assets. Qualifying assets are assets that take a substantial time to get ready for their intended use. These costs are capitalised until the asset moves into the production phase. Other borrowing costs are expensed. The foreign exchange translation loss is included in the borrowing cost calculation to the extent that it is considered to be a part of interest.
Taxation	ACCOUNTING POLICY Taxation is made up of current and deferred taxation. The current income tax charge is calculated on the basis of the tax laws enacted or substantively enacted at the balance sheet date in the countries where the group operates and generates taxable income. Management periodically evaluates positions taken in tax returns with respect to situations in which applicable tax regulations are subject to interpretation and establishes provisions where appropriate on the basis of amounts expected to be paid to the tax authorities. Deferred taxation is recognised on temporary differences existing at each reporting date between the tax base of all assets and liabilities and their carrying amounts. Substantively enacted tax rates are used to determine future anticipated effective tax rates which in turn are used in the determination of deferred taxation, except to the extent that deferred tax arises from the initial recognition of an asset or liability in a transaction that is not a business combination and does not affect the accounting or taxable profit or loss at the time of the transaction. Deferred tax is charged to profit or loss, except where the tax relates to items recognised in other comprehensive income or directly in equity in which case the tax is also recognised in other comprehensive income or directly in equity. The effect on deferred tax of any changes in tax rates is recognised in the income statement, except to the extent that it relates to items previously charged or credited directly to equity. The principal temporary differences arise from amortisation and depreciation on property, plant and equipment, provisions, unutilised tax losses, unutilised capital allowances carried forward and unrealised gains and losses on the gold forward sale contracts. Deferred tax assets relating to the carry forward of unutilised tax losses and unutilised capital allowances are recognised to the extent that it is probable that future taxable profit will be available against which the unutilised tax losses and unutilised capital allowances can be utilised. The recoverability of these assets is reviewed at each reporting date and adjusted if recovery is no longer probable. Deferred income tax is provided on temporary differences arising from investments in subsidiaries, joint ventures and associates, except where the timing of the reversal of the temporary difference is controlled by the group and it is probable that the temporary difference will not reverse in the foreseeable future. Deferred income 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 income tax assets and liabilities relate to income taxes levied by the same taxation authority on either the taxable entity or different taxable entities where there is an intention to settle the balances on a net basis.
Dividends	ACCOUNTING POLICY Dividends declared are recognised in the period in which they are approved by the board of directors. Dividends are payable in South African Rand. Cash flows from dividends paid are classified under financing activities in the cash flow statement.
Mining assets	ACCOUNTING POLICY Mining assets including mine development costs and mine plant facilities are initially recorded at cost, whereafter they are measured at cost less accumulated depreciation and impairment. Costs include expenditure that is directly attributable to the acquisition of the items. Subsequent costs are included in the asset’s carrying amount or recognised as a separate asset, as appropriate, only when it is probable that future economic benefits associated with the item will flow to the group and the cost of the item can be measured reliably. The net assets of operations placed on care and maintenance are impaired to their recoverable amount. Expenditure on the care and maintenance of these operations is charged against income, as incurred. Mineral and surface use rights represent mineral and surface use rights for parcels of land both owned and not owned by the group. Mineral and surface rights include acquired mineral use rights in production, development and exploration phase properties. The amount capitalised related to a mineral and surface right, either as an individual asset purchase or as part of a business combination, is the fair value at acquisition. The group’s mineral use rights are enforceable regardless of whether proved or probable reserves have been established. In certain limited situations, the nature of use changes from an exploration right to a mining right upon the establishment of proved and probable reserves. The group has the ability and intent to renew mineral use rights where the existing term is not sufficient to recover all identified and valued proved and probable reserves and/or undeveloped mineral interests. Depreciation Depreciation of mining assets is computed principally by the units-of-production method over life-of-mine based on estimated quantities of economically recoverable proved and probable reserves, which can be recovered in future from known mineral deposits. In most instances, proved and probable reserves provide the best indication of the useful life of the group’s mines (and related assets). However, in some instances, proved and probable reserves may not provide a realistic indication of the useful life of the mine (and related assets). This may be the case, for example, where management is confident that further inferred resources will be converted into measured and indicated resources and if they are economically recoverable, they can also be classified as proved and probable reserves. Management is approaching economic decisions affecting the mine on this basis, but has chosen to delay the work required to designate them formally as reserves. In assessing which resources to include so as to best reflect the useful life of the mine, management considers resources that have been included in the life-of-mine plan. To be included in the life-of-mine plan, resources need to be above the cut-off grade set by management, which means that the resource can be economically mined and is therefore commercially viable. This consistent systematic method for inclusion in the life-of-mine plan takes management’s view of the gold price, exchange rates as well as cost inflation into account. In declaring the resource, management would have had to obtain a specified level of confidence of the existence of the resource through drilling as required by the South African Code for Reporting Exploration Results, Mineral Resources and Mineral Reserves (SAMREC). Additional confidence in the existence, commercial viability and economical recovery of such resources may be based on historical experience and available geological information, such as geological information obtained from other operations that are contiguous to the group’s as well as where the group mines continuations of these other operations’ orebodies and reefs. This is in addition to the drilling results obtained by the group and management’s knowledge of the geological setting of the surrounding areas, which would enable simulations and extrapolations to be done with a reasonable degree of accuracy. 13 PROPERTY, PLANT AND EQUIPMENT continued MINING ASSETS continued ACCOUNTING POLICY continued Depreciation continued In instances where management is able to demonstrate the economic recovery of such resources with a high level of confidence, such additional resources, which may also include certain, but not all, of the inferred resources, as well as the associated future development costs of accessing those resources, are included in the calculation of depreciation. The future development costs are those costs that need to be incurred to access these inferred resources, for example the costs to complete a decline or level, which may include infrastructure and equipping costs. These amounts have been extracted from the cash flow projections for the life-of-mine plans. Mineral rights associated with production phase mineral interests are amortised over the life of mine using the units-of-production method in order to match the amortisation with the expected underlying future cash flows. Impairment Testing for impairment is done in terms of the group policy as discussed in note 2.5 . Scrapping of assets Where significant adverse changes have taken place relating to the useful life of an asset, that asset is tested for impairment in terms of the group policy as discussed in note 2.5 . Whether or not an impairment is recognised, it is then necessary to review the useful lives and residual values of the assets within the CGU – this is reviewed at least annually. Where necessary, the useful lives and residual values of the individual assets are revised. Where the useful life of an asset is nil as a result of no future economic benefit expected from the use or disposal of that asset, it is necessary to derecognise the asset. The loss arising from the derecognition is included in profit or loss in the period in which the asset was derecognised. Stripping activities The removal of overburden and other mine waste materials is often necessary during the initial development of an opencast mine site, in order to access the mineral ore deposit. The directly attributable cost of this activity is capitalised in full within mining assets under construction, until the point at which the mine is considered to be capable of commercial production. The removal of waste material after the point at which a mine is capable of commercial production is referred to as production stripping. When the waste removal activity improves access to ore extracted in the current period, the costs of production stripping are charged to the income statement as operating costs in accordance with the principles of IAS 2, Inventories . Where production stripping activity both produces inventory and improves access to ore in future periods the associated costs of waste removal are allocated between the two elements. The portion which benefits future ore extraction is capitalised within stripping and development capital expenditure. If the amount to be capitalised cannot be specifically identified it is determined based on the volume of waste extracted compared with expected volume for the identified component of the orebody. Components are specific volumes of a mine’s orebody that are determined by reference to the life-of-mine plan. In certain instances significant levels of waste removal may occur during the production phase with little or no associated production. The cost of this waste removal is capitalised in full. All amounts capitalised in respect of waste removal are depreciated using the units-of-production method based on proved and probable ore reserves of the component of the orebody to which they relate. The effects of changes to the life-of-mine plan on the expected cost of waste removal or remaining reserves for a component are accounted for prospectively as a change in estimate.
Mining assets under construction	ACCOUNTING POLICY At the group’s surface mines, when it has been determined that a mineral property can be economically developed as a result of establishing proved and probable reserves, costs incurred to develop the property are capitalised as incurred until the mine is considered to have moved into the production phase. These costs include costs to further delineate the orebody and remove overburden to initially expose the orebody. At the group’s underground mines, all costs incurred to develop the property, including costs to access specific ore blocks or other areas of the underground mine, are capitalised to the extent that such costs will provide future economic benefits. These costs include the cost of shaft sinking and access, the costs of building access ways, lateral development, drift development, ramps, box cuts and other infrastructure development. Revenue earned during the pre-production phase is credited to the asset. Where a depreciable asset is used in the construction or extension of a mine, the depreciation is capitalised against the mine’s cost. Exploration properties acquired are recognised in the balance sheet within development cost and are shown at cost less provisions for impairment determined in accordance with the group’s accounting policy on impairment of non-financial assets. Mineral interests associated with development and exploration phase mineral interests are not amortised until such time as the underlying property is converted to the production stage. Capitalisation of pre-production costs ceases when commercial levels of production are reached. Commercial levels of production are discussed under “production start date” above.
Undeveloped properties	ACCOUNTING POLICY Undeveloped properties are initially recognised at cost, which is generally based on the fair value of resources obtained through acquisitions. The carrying values of these properties are tested annually for impairment. Once development commences, these properties are transferred to mining properties and accounted for in accordance with the related accounting policy.
Other non-mining assets	ACCOUNTING POLICY Land is shown at cost and not depreciated. Other non-mining fixed assets are shown at cost less accumulated depreciation and accumulated impairment losses. Other non-mining fixed assets are depreciated on a straight-line basis over their estimated useful lives as follows: • Vehicles at 20% per year. • Computer equipment at 33.3% per year. • Furniture and equipment at 16.67% per year. The assets’ residual values and useful lives are reviewed, and adjusted if appropriate, at each balance sheet date.
Intangible assets	ACCOUNTING POLICY Intangible assets consist of all identifiable non-monetary assets without physical substance. They are stated at cost less accumulated amortisation and accumulated impairment losses, if any. The following are the main categories of intangible assets: Goodwill Goodwill is an intangible asset with an indefinite useful life which is not amortised but tested for impairment on an annual basis, or when there is an indication of impairment. The excess of consideration transferred over the amount of any non-controlling interest in the acquiree and the acquisition-date fair value of any previously held equity interest in the acquiree over the fair value of the group’s share of the identifiable net assets acquired is recorded as goodwill. Goodwill on acquisition of subsidiaries, joint operations and businesses is included in intangible assets. Goodwill on acquisition of associates is included in investments in associates and tested for impairment as part of the overall balance. Goodwill is tested annually for impairment and carried at cost less accumulated impairment losses. Goodwill is allocated to cash generating units for the purpose of impairment testing. The allocation is made to those cash generating units or groups of cash generating units that are expected to benefit from the business combination in which the goodwill arose. If the composition of one or more cash generating units to which goodwill has been allocated changes due to a re-organisation, the goodwill is re-allocated to the units affected. The gain or loss on disposal of an entity includes the carrying amount of goodwill relating to the entity sold. Technology-based assets Acquired computer software licences that require further internal development are capitalised on the basis of costs incurred to acquire and bring to use the specific software. These technology-based assets are classified as intangible assets with a finite useful life. These assets are amortised on a straight-line basis over their estimated useful lives, which are reviewed annually, as follows: • Computer software at 20% per year.
Financial assets	ACCOUNTING POLICY - FINANCIAL ASSETS (APPLICABLE TO NOTES 15 , 16 , 17 , 18 AND 19 ) Financial assets are initially recognised when the group becomes a party to their contractual arrangements. On initial recognition, a financial asset is classified as measured at: • Amortised cost; • Fair value through other comprehensive income (FVTOCI); or • Fair value through profit or loss (FVTPL). A financial asset is classified as measured at amortised cost if it is held within the business model whose objective is to hold assets to collect contractual cash flows and its contractual terms give rise, on specified dates, to cash flows that are solely payments of principal and interest on the principal amount outstanding. The group measures a financial asset initially at its fair value plus, in the case of a financial asset not at FVTPL, transaction costs that are directly attributable to the acquisition of the financial asset. Transaction costs of financial assets carried at FVTPL are expensed. The subsequent measurement of financial assets is discussed below. Financial asset category Description Debt instruments at amortised cost Financial assets at amortised cost consist of restricted cash, restricted investments, loans, trade receivables and cash and cash equivalents. Interest income from these financial assets is included in investment income using the effective interest rate method. Any gain or loss arising on derecognition is recognised directly in profit or loss. Impairment losses are presented in other operating expenses in the income statement. Debt instruments at fair value through profit or loss Equity-linked investments which are held to meet rehabilitation liabilities are classified as FVTPL. Debt instruments where the contractual cash flows fail to meet the solely payments of principal and interest (SPPI) criteria are also classified as FVTPL. A gain or loss on a debt investment that is subsequently measured at FVTPL is recognised in profit or loss and presented net within investment income in the period in which it arises. On derecognition of a financial asset, the difference between the proceeds received or receivable and the carrying amount of the asset is included in profit or loss. Equity instruments designated at fair value through OCI The group's equity investments are designated as FVTOCI. The group subsequently measures all equity investments at fair value. Where the group's management has elected to present fair value gains and losses on equity investments in OCI, there is no subsequent reclassification of fair value gains and losses to profit or loss following the derecognition of the investment. Dividends from such investments are recognised when the group’s right to receive payments is established either in profit or loss as other income or as a deduction against the asset if the dividend clearly represents a recovery of part of the cost of the investment. Residual values in OCI are reclassified to retained earnings on derecognition of the related FVTOCI instruments. Impairment losses on financial assets at amortised cost are assessed using the forward-looking expected credit loss (ECL) approach. ECLs are a probability-weighted estimate of credit losses. Credit losses are measured as the present value of all cash shortfalls (i.e. the difference between the cash flows due to the entity in accordance with the contract and the cash flows that the group expects to receive). At each reporting date, the group assesses whether financial assets carried at amortised cost are credit impaired. A financial asset is ‘‘credit-impaired’’ when one or more events that have a detrimental impact on the estimated future cash flows of the financial asset have occurred. Trade receivable loss allowances are measured at an amount equal to lifetime ECLs. Loss allowances are deducted from the gross carrying amount of the assets. Financial assets and liabilities are offset and the net amount reported in the balance sheet when there is a legally enforceable right to offset the recognised amounts and there is an intention to settle on a net basis, or realise the asset and settle the liability simultaneously. ACCOUNTING POLICY - FINANCIAL ASSETS (APPLICABLE TO NOTES 15 , 16 , 17 , 18 AND 19 ) continued Accounting policy applicable before 1 July 2018 Financial assets are initially measured at fair value when the group becomes a party to their contractual arrangements, with the exception of loans and receivables which are recognised on origination date. Transaction costs are included in the initial measurement of financial instruments, with the exception of financial instruments classified at fair value through profit or loss. The subsequent measurement of financial assets is discussed below. A financial asset is derecognised when the right to receive cash flows from the asset has expired or the group has transferred its rights to receive cash and either (a) has transferred substantially all the risks and rewards of the asset, or (b) has neither transferred nor retained substantially all the risks and rewards of the asset, but has transferred control of the assets. On derecognition of a financial asset, the difference between the carrying amount and the sum of the consideration received and any cumulative gain or loss recognised in equity is recognised in profit or loss. Financial assets and liabilities are offset and the net amount reported in the balance sheet when there is a legally enforceable right to offset the recognised amounts and there is an intention to settle on a net basis, or realise the asset and settle the liability simultaneously. The group classifies financial assets as follows: • Loans and receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. They arise when the group provides money, goods or services directly to a debtor with no intention of trading the receivable. Loans and receivables are subsequently measured at amortised cost using the effective interest method. Loans and receivables include trade and other receivables (excluding VAT and prepayments), restricted cash and cash and cash equivalents. Cash and cash equivalents are defined as cash on hand, deposits held at call with banks and short-term highly liquid investments with original maturities of three months or less. Cash and cash equivalents exclude restricted cash. Trade and other receivables are recognised initially at fair value and subsequently measured at amortised cost using the effective interest method, less provision for impairment. If collection of the trade receivable is expected in one year or less it is classified as current assets. If not, it is presented as non-current assets. A provision for impairment of receivables is established when there is objective evidence that the group will not be able to collect all amounts due according to the original terms of receivables. The amount of the provision is the difference between the asset’s carrying amount and the present value of estimated future cash flows, discounted at the effective interest rate. The carrying amount of the asset is reduced through the use of a provision for impairment (allowance account) and the amount of the loss is recognised in the income statement. When a trade receivable is uncollectible, it is written off against the allowance account for trade receivables. Subsequent recoveries of amounts previously written off are credited in the income statement. • Available-for-sale financial assets are non-derivatives that are either designated in this category or not classified in any of the other categories. They are included in non-current assets unless the investment matures or management intends to dispose of the investment within 12 months of the balance sheet date. Available-for-sale financial assets are subsequently carried at fair value. The fair values of quoted investments are based on current bid prices. If the fair value for a financial instrument cannot be obtained from an active market, the group establishes fair value by using valuation techniques. The group assesses at each balance sheet date whether there is objective evidence that a financial asset or a group of financial assets is impaired. • Held-to-maturity investments are non-derivative financial assets with fixed or determinable payments and fixed maturities that the group’s management has the positive intention and ability to hold to maturity. The group’s held-to-maturity investments are subsequently measured at amortised cost using the effective interest method. The group assesses at the end of each reporting period whether there is objective evidence that a held-to-maturity investment is impaired as a result of an event. A portion of restricted investments held by the trust funds (refer to note 16 ) are classified as held-to-maturity investments. • Financial assets at fair value through profit or loss have two sub-categories: financial assets held-for-trading, and those designated at fair value through profit or loss at inception. Derivative assets are categorised as held for trading unless designated as hedging instruments (refer to note 2.3 ). These assets are subsequently measured at fair value with gains or losses arising from changes in fair value recognised in the income statement in the period in which they arise.
Environmental trust funds	ACCOUNTING POLICY Contributions are made to the group's environmental trust funds, created in accordance with statutory requirements, to fund the estimated cost of pollution control, rehabilitation and mine closure at the end of the life of the group's mines. The trusts are consolidated into the group as the group exercises control of the trusts. The measurement of the investments held by the trust funds is dependent on their classification under financial assets. Income received and gains are treated in accordance with these classifications. The equity-linked notes are classified and measured at fair value through profit or loss whilst the interest-bearing short-term investments are classified and measured as debt instruments at amortised cost.
Inventories	ACCOUNTING POLICY Inventories, which include bullion on hand, gold-in-process, gold in lock-up, ore stockpiles and consumables, are measured at the lower of cost and net realisable value. Net realisable value is assessed at each reporting date and is determined with reference to relevant market prices. The cost of bullion, gold-in process and gold in lock-up is determined by reference to production cost, including amortisation and depreciation at the relevant stage of production. Ore stockpiles are valued at average production cost. Stockpiles and gold in lock-up are classified as non-current assets where the stockpile's volume exceeds current processing capacity and where a portion of static gold in lock-up is expected to be recovered more than 12 months after balance sheet date. Gold in-process inventories represent materials that are currently in the process of being converted to a saleable product. In-process material is measured based on assays of the material fed to process and the projected recoveries at the respective plants. In-process inventories are valued at the average cost of the material fed to process attributable to the source material coming from the mine or stockpile plus the in-process conversion costs, including the applicable depreciation relating to the process facility, incurred to that point in the process. Gold in-process includes gold in lock-up which is generally measured from the plants onwards. Gold in lock-up is expected to be extracted when plants are demolished at the end of their useful lives, which is largely dependent on the estimated useful life of the operations feeding the plants. At the group’s open pit operations, gold in-process represents production in broken ore form. Consumables are valued at weighted average cost value after appropriate allowances for slow moving and redundant items.
Issued capital	ACCOUNTING POLICY Ordinary shares are classified as equity, incremental costs directly attributable to the issue of new shares or options are shown in equity as a deduction, net of tax, from the proceeds. The cost of treasury shares is eliminated against the share capital balance.
Provisions	ACCOUNTING POLICY - PROVISIONS (APPLICABLE TO NOTES 25 , 26 , 27 AND 29 ) Provisions are recognised when the group has a present legal or constructive obligation as a result of past events where it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation, and a reliable estimate of the amount of the obligation can be made. The amount recognised as a provision is the net present value of the best estimate of the expenditure required to settle the present obligation at balance sheet date using a pre-tax rate that reflects current market assessment of the time value of money and the risks specific to the obligation. The estimate takes into account the associated risks and uncertainties. The increase in the provision due to the passage of time is recognised as interest expense. Provisions are reviewed at each balance sheet date and adjusted to reflect the current best estimate. If it is no longer probable that an outflow of economic benefits will be required, the provision is reversed.
Provision for environmental rehabilitation	ACCOUNTING POLICY Estimated long-term environmental obligations, comprising pollution control, rehabilitation and mine closure, are based on the group’s environmental management plans in compliance with current technological, environmental and regulatory requirements. Based on disturbances to date, the net present value of expected rehabilitation cost estimates is recognised and provided for in full in the financial statements. The estimates are reviewed annually and are discounted using a pre-tax risk-free rate that is adjusted to reflect the current market assessments of the time value of money and the risks specific to the obligation. Annual changes in the provision consist of finance costs relating to the change in the present value of the provision and inflationary increases in the provision estimate, as well as changes in estimates. The present value of environmental disturbances created are capitalised to mining assets against an increase in the rehabilitation provision. If a decrease in the liability exceeds the carrying amount of the asset, the excess is recognised immediately in the income statement. If the asset value is increased and there is an indication that the revised carrying value is not recoverable, impairment is performed in accordance with the accounting policy dealing with impairments of non-financial assets (refer to note 2.5 ). Rehabilitation projects undertaken included in the estimates are charged to the provision as incurred. The cost of ongoing current programmes to prevent and control pollution is charged against income as incurred. Over time, the liability is increased to reflect an interest element, and the capitalised cost is depreciated over the life of the related asset.
Leases	ACCOUNTING POLICY The leases accounting policy is applicable from 1 July 2019. The group assesses the presence of a lease in a contract as at the commencement date of the agreement. Having determined that a contract contains a lease asset (and respective contractual cash obligations), Harmony recognises a right-of-use asset and lease liability. The group discloses expensed amounts for contracts assessed as variable leases, low value asset leases and short-term leases. The disclosed value of these expensed leases is either determined on a straight-line basis over the duration of the lease or on a systematic basis that fairly indicates the consumption of the lease contract. All expensed lease contracts are recognised in production costs, corporate, administration and other expenditure in the income statement. The lease liability is initially measured at the present value of the lease payments that are not paid at the commencement date, discounted by using the rate implicit in the lease. If this rate cannot be readily determined, the group uses its incremental borrowing rate. The group has applied the IFRS 16 portfolio approach in determining the discount rate for leases. As such a single discount rate has been used for contracts that share similar characteristics. The group has determined that a portfolio of contracts that are denominated in the same currency may use a single discount rate. This rate has been determined using various factors including in-country borrowings as well as other sources of finance. The nature of the right-of-use assets was also considered. Lease payments included in the measurement of the lease liability comprise: • Fixed lease payments (including in-substance fixed payments), less any lease incentives; • Variable lease payments that depend on an index or rate, initially measured using the index or rate at the commencement date; • The amount expected to be payable by the lessee under residual value guarantees; • The exercise price of purchase options, if the lessee is reasonably certain to exercise the options; and • Payments of penalties for terminating the lease, if the lease term reflects the exercise of an option to terminate the lease. The non-current and current portions of the lease liability is included in other non-current liabilities and trade and other payables in the balance sheet respectively. The lease liability is subsequently measured by increasing the carrying amount to reflect interest on the lease liability (using the effective interest method) and by reducing the carrying amount to reflect the lease payments made. The group remeasures the lease liability (and makes a corresponding adjustment to the related right-of-use asset) whenever: • The lease term has changed or there is a change in the assessment of exercise of a purchase option, in which case the lease liability is remeasured by discounting the revised lease payments using a revised discount rate; • The lease payments change due to changes in an index or rate or a change in expected payment under a guaranteed residual value, in which cases the lease liability is remeasured by discounting the revised lease payments using the initial discount rate (unless the lease payments change is due to a change in a floating interest rate, in which case a revised discount rate is used). • A lease contract is modified and the lease modification is not accounted for as a separate lease, in which case the lease liability is remeasured by discounting the revised lease payments using a revised discount rate. The right-of-use assets comprise the initial measurement of the corresponding lease liability, lease payments made at or before the commencement day, any initial direct costs and restoration costs as described below. They are subsequently measured at cost less accumulated depreciation and impairment losses. The lease term shall be determined as the non-cancellable period of a lease, together with: • Periods covered by an option to extend the lease if management is reasonably certain to make use of that option; and / or • Periods covered by an option to terminate the lease, if management is reasonably certain not to make use of that option. Whenever the group incurs an obligation for costs to dismantle and remove a leased asset, restore the site on which it is located or restore the underlying asset to the condition required by the terms and conditions of the lease, a provision is recognised and measured under IAS 37 Provisions, Contingent Liabilities and Contingent Assets . The costs are included in the related right-of-use asset, unless those costs are incurred to produce inventories. Right-of-use assets are depreciated over the shorter period of lease term and useful life of the underlying asset. If a lease transfers ownership of the underlying asset or the cost of the right-of-use asset reflects that the group expects to exercise a purchase option, the related right-of-use asset is depreciated over the useful life of the underlying asset. The depreciation starts at the commencement date of the lease. The right-of-use assets are presented in the property, plant and equipment line in the balance sheet. The group applies its existing accounting policy on impairment of non-financial assets to determine whether a right-of-use asset is impaired and accounts for any identified impairment loss accordingly.
Financial liabilities	ACCOUNTING POLICY - FINANCIAL LIABILITIES (APPLICABLE TO NOTES 30 AND 31 ) Financial liabilities are initially measured at fair value when the group becomes a party to their contractual arrangements. Transaction costs are included in the initial measurement of financial liabilities, with the exception of financial liabilities classified at fair value through profit or loss. The subsequent measurement of financial liabilities is discussed below. A financial liability is derecognised when the obligation under the liability is discharged, cancelled or expires. The group classifies financial liabilities as follows: • Borrowings are initially recognised at fair value net of transaction costs incurred and subsequently measured at amortised cost, comprising original debt less principal payments and amortisation, using the effective yield method. Any difference between proceeds (net of transaction cost) and the redemption value is recognised in the income statement over the period of the borrowing using the effective interest rate method. Fees paid on the establishment of the loan facilities are capitalised as a pre-payment and amortised over the period of the facility to which it relates, to the extent it is probable that some or all of the facility will be drawn down. To the extent there is no evidence that it is probable that some or all of the facility will be drawn down, the fee is expensed. Borrowings are classified as current liabilities unless the group has an unconditional right to defer settlement of the liability for at least 12 months after the balance sheet date. • Trade and other payables are recognised initially at fair value and subsequently measured at amortised cost using the effective interest method. Payables are classified as current liabilities if payment is due within a year or less. If not, they are presented as non-current liabilities.
Trade and other payables	ACCOUNTING POLICY The group accrues for the cost of the leave days granted to employees during the period in which the leave days accumulate.
Employee benefits	The group provides medical cover to current employees and certain retirees through certain funds. The medical accounting costs for the defined benefit plan are assessed using the projected unit credit method. The health care obligation is measured at the present value of the estimated future cash outflows using government bond interest rates consistent with the terms and risks of the obligation. Actuarial gains and losses as a result of these valuations are recognised in other comprehensive income (OCI) at revaluation date. Actuarial gains and losses recognised in OCI will not be recycled to profit or loss. The future liability for current and retired employees and their dependants is accrued in full based on actuarial valuations obtained annually. ACCOUNTING POLICY • Pension, provident and medical benefit plans are funded through monthly contributions. The group pays fixed contributions into a separate entity in terms of the defined contribution pension, provident and medical plans which are charged to the income statement in the year to which they relate. The group's liability is limited to its monthly determined contributions and it has no further liability, legal or constructive, if the fund does not hold sufficient assets to pay all employees the benefits relating to employee service in the current and prior periods. Refer to note 27 for details of the post-retirement medical benefit plan. • Termination benefits are payable when employment is terminated before the normal retirement date, or whenever an employee accepts voluntary redundancy in exchange for these benefits. The group recognises termination benefits at the earlier of the following dates: (a) when the group can no longer withdraw the offer of those benefits; and (b) when the entity recognises costs for a restructuring that is within the scope of IAS 37, Provisions, Contingent Liabilities and Contingent Assets , and involves the payment of termination benefits. In the case of an offer made to encourage voluntary redundancy, the termination benefits are measured based on the number of employees expected to accept the offer. Benefits falling due more than 12 months after balance sheet date are discounted to present value.
Share-based payments	ACCOUNTING POLICY The group operates the following employee share incentive plans where the group granted share options to certain employees in exchange for services received: • The 2006 equity-settled share-based payments plan; • The equity-settled Sisonke Employee Share Ownership Plan (ESOP) awarded in 2019; and • The equity-settled Management Deferred Share Plan (DSP) awarded during the 2020 financial year. Equity-settled share-based payments are measured at fair value that includes market performance conditions but excludes the impact of any service and non-market performance conditions of the equity instruments at the date of the grant. The share-based payments are expensed over the vesting period, based on the group's estimate of the shares that are expected to eventually vest. The group used an appropriate option pricing model in determining the fair value of the options granted. Non-market vesting conditions are included in assumptions about the number of options that are expected to vest. At each balance sheet date, the estimates of the number of options that are expected to become exercisable are revised. The impact of the revision of original estimates, if any, is recognised in the income statement, with a corresponding adjustment to equity. The proceeds received (if any) net of any directly attributable transaction costs are credited to share capital and premium when the options are exercised.
Segment report	ACCOUNTING POLICY Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision-maker (CODM). The chief operating decision-maker has been identified as the CEO's office.

Employee termination costs are included, except for employee termination costs associated with major restructuring and shaft closures, which are separately disclosed. Production costs increased during the 2020 year mainly in line with expectations, with the South African national lockdown from the end of March 2020 due to COVID-19 impacting on production volumes while the cost base remained mostly unchanged. Contributing to the increase year on year is a decrease of R557 million in the capitalised stripping credit related to the Hidden Valley operation. 6 COST OF SALES continued (a) Production costs continued Production costs, analysed by nature, consist of the following: SA Rand Figures in million 2020 2019 2018 Labour costs, including contractors 13 004 12 715 9 750 Consumables 5 441 5 532 3 418 Water and electricity 3 664 3 398 2 551 Insurance 154 126 86 Transportation 377 354 121 Change in inventory (70 ) (166 ) (211 ) Capitalisation of mine development costs (1 485 ) (1 880 ) (1 552 ) Stripping activities (675 ) (1 197 ) (167 ) Royalty expense 327 193 121 Other 1 311 1 249 967 Total production costs 22 048 20 324 15 084 (b) Lower production volumes during the 2020 year, partially due to the closure of underground mines following the announcement of the South African national lockdown due to COVID-19, impacted on the depreciation recorded and contributed to the decrease year on year. The completion of the mining of Stage 5 at Hidden Valley during the December 2019 quarter also contributed to the decrease. The impairments recognised on certain operations in South Africa during the 2019 year significantly impacted on the base which depreciation is calculated on and the lower carrying values contributed to the lower total compared to the comparative period. Amortisation and depreciation of assets other than mining assets includes the amortisation of intangible assets. (c) For the assumptions used to calculate the rehabilitation costs, refer to note 25 . This expense includes the change in estimate for the rehabilitation provision where an asset no longer exists as well as costs related to the rehabilitation process. For 2020 , R47 million ( 2019 : R86 million ) ( 2018 : R94 million ) was spent on rehabilitation in South Africa. Refer to note 25 . (d) The employment termination and restructuring expenditure for 2020, 2019 and 2018 relates to the voluntary severance program in place to reduce labour costs. (e) Refer to note 34 for details on the share-based payment schemes implemented by the group. (f) Management performed an assessment for impairment triggers as well as indications of reversal of previously recorded impairment losses at 30 June 2020. Due to the uncertainty of the impact of the COVID-19 pandemic and the South African national lockdown would have on the South African underground operations, as well as the increase in the short-term gold price, the recoverable amounts for these cash-generating units (CGUs) were calculated. Based on the impairment tests performed, no impairments were recorded for the 2020 year. Where CGUs had previously been impaired, management considered whether the impairment loss (or the contributors to the previously recognised impairment loss) no longer exists or might have decreased. Management considered general and specific factors for each CGU and concluded that although overall the gold price had improved from the time that the impairment losses had been recognised, the specific circumstances that led to the original impairments had not reversed. Management also considered the level of uncertainty of the impact of COVID-19 on production and therefore on the cash flows. Due to the volatility embedded in the potential upside driven by the higher gold prices in the short to medium term, coupled with the fact that the factors resulting in the previously recognised impairment losses had not reversed, management resolved it to be appropriate for no reversal of previously recognised impairment losses to be recorded for the period under review. Refer to note 13 for further information. 6 COST OF SALES continued (f) Impairment continued The impairment of assets consists of the following: SA Rand Figures in million 2020 2019 2018 Tshepong Operations — 2 254 988 Kusasalethu — 690 579 Target 1 — 312 699 Target 3 — 318 — Joel — 198 160 Other mining assets — 120 319 Bambanani — 6 — Doornkop — — 317 Unisel — — 487 Masimong — — 329 Target North — — 1 458 Total impairment of assets — 3 898 5 336 There was no reversal of impairment for the 2020, 2019 or 2018 financial years.

Income Taxes [Abstract]
Disclosure of Taxation (Expense)/Credit	The taxation (expense)/credit for the year is as follows: SA Rand Figures in million 2020 2019 2018 SA taxation Mining tax (a) (56 ) (19 ) (42 ) - current year (61 ) (14 ) (42 ) - prior year 5 (5 ) — Non-mining tax (b) (2 ) (124 ) (163 ) - current year (2 ) (121 ) (163 ) - prior year — (3 ) — Deferred tax (c) (197 ) 282 439 - current year (197 ) 282 439 Total taxation (expense)/credit (255 ) 139 234 (a) Mining tax on gold mining taxable income in South Africa is determined according to a formula, based on the taxable income from mining operations. 5% of total revenue is exempt from taxation while the remainder is taxable at a higher rate ( 34% ) than non-mining income ( 28% ) as a result of applying the gold mining formula. Mining and non-mining income of Australian entities and PNG operation are taxed at a standard rate of 30% . All qualifying mining capital expenditure is deducted from taxable mining income to the extent that it does not result in an assessed loss. Accounting depreciation is eliminated when calculating the South African mining tax income. Excess capital expenditure is carried forward as unredeemed capital to be claimed from future mining taxable income. The group has several tax paying entities in South Africa. In terms of the mining ring-fencing application, each ring-fenced mine is treated separately and deductions can normally only be utilised against mining income generated from the relevant ring-fenced mine. (b) Non-mining taxable income of mining companies and the taxable income for non-mining companies are taxed at the statutory corporate rate of 28% .The expense for the 2019 and 2018 years relates to non-mining tax arising from derivative gains (realised and unrealised) recognised on the foreign currency derivatives as well as the realised gains on the commodity forward sale contracts. During 2020, the losses on the derivative contracts resulted in non-mining tax losses. See discussion on deferred tax below. Refer to note 18 for details on the group's derivative gains and losses recorded. (c) The deferred tax rate used to calculate deferred tax is based on the current estimate of future profitability when temporary differences will reverse based on tax rates and tax laws that have been enacted at the balance sheet date. Depending on the profitability of the operations, the deferred tax rate can consequently be significantly different from year to year. Following the completion of the annual life-of-mine plans, management revised the weighted average deferred tax rates for all the South African operations. The higher short-term gold price assumption used resulted in an increase in the estimated profitability and consequently higher rates than in the prior year. Refer to note 13 for the assumptions used. These changes, together with changes in the temporary differences, had the following impacts: • The change in rates on temporary differences at the individual company level, other than hedge accounted derivatives, resulted in an increase in the deferred tax expense and liability to the amount of R493 million . • Unwinding of temporary differences related to unredeemed capital expenditure balance resulted in an increase of R298 million in the deferred tax expense. • The weakening of the Rand against the US$ and the increase in the commodity prices negatively impacted on the valuation of the derivative financial instruments. Refer to notes 18 and 37 for detail. The temporary differences related to the Rand gold derivatives changed from taxable temporary differences (ie resulting in a deferred tax liability) to deductible temporary differences (resulting in a deferred tax asset). Management assessed the rates at which the temporary differences are expected to reverse and as the expected non-mining losses can be set off against the mining profits, the rates have been revised from the non-mining tax rate of 28% to the weighted average deferred tax rate. This accounts for R510 million of the deferred tax credit directly charged to other comprehensive income. 10 TAXATION continued (c) Deferred tax continued • The net deferred tax positions for each of the group's entities are assessed separately. Two companies have net deferred tax asset positions and therefore recoverability of these assets was considered. The position at 30 June 2020 was as follows: SA Rand Figures in million Harmony Company Randfontein Estates Deductible/(taxable) temporary differences 1 079 (155) Tax losses 574 534 Total 1 653 379 Deferred tax rate 29.8 % 10.1 % Deferred tax asset 492 39 At 30 June 2020, management considered whether the unrecognised deferred tax asset (DTA) related to the Harmony company should be recognised, partially or in full. A portion of the DTA relates to a tax loss of R574 million , which primarily arose due to the foreign exchange translation losses and losses on derivatives recorded in 2020. The company's operations include the Central Plant Reclamation (CPR), a tailings retreatment facility. As a low cost producer, its profit margins are highly sensitive to fluctuations in the gold price. In addition, the higher short-term gold price also significantly benefits Masimong's profitability, which following the revision of its life-of-mine at 30 June 2020 has two years remaining of its life. Due to the significant expected increase in the short-term Rand gold price used in the estimation of future taxable profits for the mining operations owned by the Harmony company, it is considered probable that sufficient future taxable profits will be available against which the aforementioned tax loss and the current deductible temporary differences existing at the reporting date can be utilised. Consequently, a deferred tax asset of R492 million has been recognised, consisting of R171 million relating to the tax loss and R321 million relating to deductible temporary differences. Management believes there will be sufficient future taxable income from the operations owned by Randfontein Estates Limited and therefore the entire balance of R39 million was recognised at 30 June 2020.
Disclosure of Major Items Causing the Income Tax Provision to Differ from the South African Mining Statutory Tax Rate	Major items causing the group's income tax provision to differ from the South African mining statutory tax rate of 34% were: SA Rand Figures in million 2020 2019 2018 Tax on net loss at the mining statutory tax rate 202 934 1 600 Non-allowable deductions (221 ) (241 ) (513 ) Share-based payments (62 ) (70 ) (104 ) Impairment of assets — (2 ) (219 ) Loan-related costs (19 ) (18 ) (24 ) Exploration expenditure (55 ) (36 ) (74 ) Finance costs (76 ) (68 ) (54 ) Other (9 ) (47 ) (38 ) Movement in temporary differences related to property, plant and equipment (355 ) (1 388 ) (1 248 ) Movements in temporary differences related to other assets and liabilities (452 ) 98 55 Difference between effective mining tax rate and statutory mining rate on mining income 10 (175 ) (550 ) Difference between non-mining tax rate and statutory mining rate on non-mining income — 19 35 Effect on temporary differences due to changes in effective tax rates 1 (469 ) 83 675 Prior year adjustment 5 (8 ) — Capital allowances 2 766 684 604 Deferred tax asset not recognised 3 34 133 (424 ) Deferred tax asset previously not recognised now recorded 4 225 — — Income and mining taxation (255 ) 139 234 Effective income and mining tax rate (%) (43 ) 5 5 1 This mainly relates to movements in the deferred tax rate related to Harmony ( 25.7% to 29.8% ) ( 2019 : 10.5% to 25.7% ) ( 2018 : 19.4% to 10.5% ), Freegold ( 8.1% to 11.4% ) ( 2019 : 8.7% to 8.1% ) ( 2018 : 12.5% to 8.7% ), Randfontein Estates Limited (Randfontein) ( 4.5% to 10.1% ) ( 2019 : 1.8% to 4.5% ) ( 2018 : 3.8% to 1.8% ) and Moab ( 4.7% to 17.3% ) ( 2019 : 9.1% to 4.7% ) ( 2018 : 9.1% ). 2 This relates to the additional capital allowance that may be deducted from taxable income from mining operations in South Africa. A significant portion relates to Avgold Limited (Avgold) which has a 0% effective tax rate. 3 This relates to tax losses and deductible temporary differences for which future taxable profits are uncertain and are not considered probable. 4 Harmony company has sufficient future profits as well as taxable temporary differences which the deductible temporary differences can be reversed against. Therefore the deferred tax asset not recognised in the 2019 year has been recognised.

The issue price and the exercise price of share options issued to employees include the fair value of any service to be supplied to the entity in the future under the share option or other share-based payment arrangement. 2 The dilution is as a result of the potential reduction in earnings attributable to equity holders of the parent company as a result of the exercise of the Tswelopele Beneficiation Operation (TBO) option. TBO contributed a profit for the six months ended 31 December 2019 and therefore the reduction in earnings attributable to Harmony would increase the loss and loss per share. Following the vesting of the option (refer to note 34 ), there has been no further impact.

Disclosure of Sensitivity Analysis - Impairment of Assets	The impairment of assets consists of the following: SA Rand Figures in million 2020 2019 2018 Tshepong Operations — 2 254 988 Kusasalethu — 690 579 Target 1 — 312 699 Target 3 — 318 — Joel — 198 160 Other mining assets — 120 319 Bambanani — 6 — Doornkop — — 317 Unisel — — 487 Masimong — — 329 Target North — — 1 458 Total impairment of assets — 3 898 5 336 There was no reversal of impairment for the 2020, 2019 or 2018 financial years. The recoverable amounts for these assets have been determined on a fair value less costs to sell basis using the assumptions per note 13 in discounted cash flow models and attributable resource values. These are fair value measurements classified as level 3. The recoverable amounts of the CGUs where impairments were recognised as at 30 June 2019 are as follows: SA Rand Recoverable amount Figures in million Life-of-Mine plan Resource base Total Tshepong Operations The impairment was due to the increased costs to exploit the resource base as well as a lower expected recovered grade. The decrease in the recovery grade is as a result of the change in the dilution factors applied to the outside life of mine resources. 3 811 2 055 5 866 Kusasalethu The decrease in grade and increased estimated costs in the resource base resulted in a lower recoverable amount. The decrease in the recovery grade is as a result of the change in the dilution factors applied to the outside life of mine resources. 1 297 — 1 297 Target 1 The recoverable amount decreased as a result of increased costs and decrease in grade in the resource base together with the estimated impact of carbon tax. The increase in discount rate due to increased risk factors also negatively impacted on the recoverable amount. 467 609 1 076 Target 3 The operation remained under care and maintenance. A change in valuation method from discounted cash flow model to resource multiple approach reduced the recoverable amount. None 182 182 Joel The increased capital costs in the resource base together with carbon tax negatively impacted the net present value of expected cash flows. 765 87 852 Other mining assets The updated life-of-mine plans for the CGUs in Freegold and Avgold resulted in the impairment of other mining assets. 335 None 335 Bambanani The impairment of goodwill reduced the carrying amount of intangible assets. As goodwill is not depreciated, it resulted in an impairment as the life of the operation shortens. 763 None 763 6 COST OF SALES continued (f) Impairment continued The recoverable amounts of the CGUs where impairments were recognised as at 30 June 2018 are as follows: SA Rand Recoverable amount Figures in million Life-of-Mine plan Resource base Total Tshepong Operations The impairment was mainly driven by sensitivity to fluctuations in the gold price. Furthermore the updated life-of-mine for the Tshepong operations presented a marginal decrease in recovered grade. 4 279 3 147 7 426 Kusasalethu Kusasalethu's old section of the mine at the operation was excluded in the FY19 life-of-mine plan. 1 019 1 119 2 138 Target 1 Exploration drilling results during the year pointed towards lower grade estimates within certain blocks that have now been excluded from the life-of-mine plans. 471 746 1 217 Joel The updated life-of-mine for the Joel operation presented a marginal decrease in recovered grade. 540 336 876 Other mining assets The updated life-of-mine plans for the CGUs in Freegold and Harmony resulted in the impairment of other mining assets. 366 None 366 Doornkop The impairment of Doornkop is primarily as a result of a decrease in the Kimberley Reef's resource values. 1 552 1 178 2 730 Unisel Excluded the Leader Reef from the life-of-mine plan to focus on the higher grade Basal Reef. This reduced the life-of-mine from four years to eighteen months. 38 None 38 Masimong The impairment at Masimong was as a result of the depletion of the higher grade B Reef and subsequent reduced life-of-mine. 58 None 58 Target North The impairment of Target North was as a result of a decrease in resource values. None 3 681 3 681 The sensitivity scenario of a 10% decrease or increase in the commodity price used in the discounted cash flow models and the resource values used (with all other variables held constant) would have resulted in the following impairment being recorded as at 30 June 2020 and 2019 : SA Rand Figures in million 2020 2019 - 10% decrease Tshepong Operations 3 352 7 155 Target 1 804 1 278 Joel 716 984 Kusasalethu 441 1 962 Bambanani 1 94 331 Other Freegold assets 20 — Moab Khotsong 1 15 2 758 Unisel 6 45 Doornkop — 1 350 Hidden Valley — 749 Target 3 — 337 Target North — 291 Other surface operations — 178 Masimong — 105 Kalgold — 39 + 10% increase Target 3 — 300 1 The carrying amounts of these CGUs include goodwill and any impairment losses are allocated first to goodwill and then to the identifiable assets.

Harmony is a concurrent creditor in the Pamodzi Orkney liquidation. 17 OTHER NON-CURRENT ASSETS continued (b) During 2016, Harmony advanced R200 million to the ARM BBEE Trust, a shareholder of African Rainbow Minerals Limited (ARM). The trust is controlled and consolidated by ARM, who holds 12.38% of Harmony's shares at 30 June 2020. Harmony is a trustee of the ARM BBEE Trust. The loan is subordinated and unsecured. The interest is market related (3 months JIBAR plus 4.25% ) and is receivable on the maturity of the loan on 31 December 2022. On adoption of IFRS 9 in 2019, it was assessed that the contractual cash flows fail the solely payments of principal and interest (SPPI) characteristics an d that the loan will therefore be carried at fair value through profit or loss and t he previously recognised provision was derecognised.The group determined that the contractual terms include exposure to risk and volatility that is inconsistent with a basic lending arrangement. In making this assessment the group considered contingent events that would change the amount and timing of cash flows and potential limits on the group's claim to cash flows from specified assets (e.g. non-recourse asset arrangements). At 30 June 2020 the loan has been remeasured to its fair value of R306 million (2019: R271 million ) using a discounted cash flow model. The fair value adjustment is recorded in gains on financial instruments - refer to note 8 . (c) On adoption of IFRS 9 on 1 July 2018, an irrevocable election was made to classify the equity instruments previously classified as available-for-sale as at FVOCI. The new standard impacted the measurement of the group's unquoted equity investments as IFRS 9 eliminated the exemption provided under IAS 39 where unquoted equity investments were measured at cost when fair value could not be reliably measured. This change resulted in revaluing the unlisted investment in Rand Mutual Assurance, which had a cost of Rnil to fair value of R82 million in 2019. The difference between the carrying amounts of financial instruments before the adoption of IFRS 9 and the new carrying amount calculated in accordance with the standard at 1 July 2018 was recognised directly in the opening balance of equity. Refer to the statements of changes in equity. The movement in the investment in Rand Mutual Assurance is as follows: SA Rand Figures in million 2020 2019 Balance at beginning of year 52 — Fair value on adoption of IFRS 9 — 82 Capital dividend received (7 ) (30 ) Fair value gain 24 — Balance at end of year 69 52 On 6 December 2019, RMA declared a dividend that relates to the first tranche of the contingent consideration for the sale of shares in one of its subsidiaries.The dividend is seen as a recovery of capital as it reduced Harmony's effective share in the investment. The dividend relating to the second tranche of the contingent consideration is expected to be received during the 2021 financial year. The fair value gains are a result of the favourable financial position of the total investment. Please refer to note 37 on the fair value valuation technique.

Refer to note 37 for a summary of the risk management strategy applied and the balances relating to designated hedging instruments as at reporting date. Hedge effectiveness is determined at the inception of the hedge relationship and through periodic prospective effectiveness assessments. The group enters into gold forward contracts that have similar terms as the hedged item, such as notional amount, maturity date and reference gold spot price thereby ensuring that an economic relationship exists between the hedging instrument and the hedged item and resulting in a hedge ratio of 1 :1. Potential sources of hedge ineffectiveness include counterparty and own credit risk, day one gains and losses, a mismatch in the timing of the derivative and underlying gold sale maturities, location differential and the refining margin. Hedge ineffectiveness is measured by comparing the change in the expected cash flows from a forward sale contract versus the sale of an equivalent quantity of gold in the open market. Ineffectiveness results when the changes in the fair values in the hedging instruments exceed the fair value changes in the hedged item. A negligible amount of hedge ineffectiveness was experienced in the years presented. The gains and losses from derivative contracts to which hedge accounting is not applied is included in gains/(losses) on derivatives in profit or loss. (a) Rand gold contracts Discontinuance of hedge accounting As a result of the original 21-day lockdown announced in South Africa, effective 27 March 2020, aimed to slow the spread of COVID-19, Harmony placed all deep-level underground mines in South Africa on care and maintenance. As a result, a significant volume of the underlying exposure that was originally intended to be hedged was delayed. A total of 63 400 ounces of gold forwards were originally set to mature in the months of April and May 2020. After assessing forecasts of gold production at 1 April 2020, the hedged items, being the sales of gold, relating to 30 500 ounces of gold forwards were assessed to no longer be probable. The hedged items relating to the remaining balance of gold forwards were still considered to be highly probable. Due to the fact that the occurrence of the forecast transactions/hedged items were no longer considered probable, there was no longer an effective hedging relationship and therefore hedge accounting for these hedges was discontinued. Unrealised losses relating to the hedges amounting to R48 million and R187 million of restructured contracts discussed below, previously recognised in other comprehensive income, were immediately reclassified to profit or loss as gains/losses on derivatives. Restructuring of contracts In response to the gold forwards’ hedged items no longer being probable and in order to better match the cash flows relating to the underlying exposure, certain of the Rand gold forwards with maturities between 15 April 2020 and 31 May 2020 were effectively extended to mature between the periods July 2020 and March 2021. The restructured gold forwards retained the pricing of the original forwards. They were not designated as hedging instruments as the difference in the costing structure would have required a different effectiveness assessment than currently used by management. Unrealised losses relating to the hedges amounting to R187 million , previously recognised in other comprehensive income, were immediately reclassified to profit or loss as gains/losses on derivatives. All future gains and losses on the restructured hedges will be recognised in profit or loss. Subsequently, losses of R70 million have been recognised in profit or loss. (b) US$ commodity contracts Harmony maintains a derivative programme for Hidden Valley by entering into commodity derivative contracts. The contracts comprise US$ gold forward sale contracts as well as silver zero cost collars which establish a minimum (floor) and maximum (cap) silver sales price. Hedge accounting is applied to all US$ gold forward sale contracts entered into from 1 January 2019 and these are shown separately from the silver zero cost collars that are not hedge accounted. (c) Foreign exchange contracts Harmony maintains a foreign exchange derivative programme in the form of zero cost collars, which sets a floor and cap Rand/US$ exchange rate at which to convert US dollars to Rands, and foreign exchange forward contracts. Hedge accounting is not applied to these contracts. 18 DERIVATIVE FINANCIAL INSTRUMENTS continued The following table shows the open position at the reporting date: FY2021 FY2022 TOTAL Q1 Q2 Q3 Q4 Q1 Q2 Q3 Q4 Foreign exchange contracts Zero cost collars US$m 116 115 99 65 47 42 27 — 511 Average Floor 15.36 15.40 15.44 15.91 16.32 16.93 17.99 — 15.81 Average Cap 16.45 16.58 16.62 17.28 17.90 18.54 19.65 — 17.09 Forward contracts US$m 66 44 35 12 9 9 8 — 183 Average Forward rate 15.83 15.82 16.13 16.93 18.18 18.41 18.71 — 16.38 R/gold '000 oz - restructured 8 8 8 — — — — — 24 '000 oz - cash flow hedge 80 78 77 71 61 44 25 10 446 Average R'000/kg 673 679 691 737 806 851 950 1037 743 US$/gold '000 oz - cash flow hedge 12 12 12 12 12 12 10 5 87 Average US$/oz 1 413 1 442 1 489 1 521 1 561 1 606 1 710 1 760 1 543 Total gold '000 oz 100 98 97 83 73 56 35 15 557 US$/silver '000 oz 360 340 300 270 230 90 10 — 1 600 Average Floor 17.47 17.87 18.01 18.17 18.21 17.86 18.40 — 17.91 Average Cap 18.92 19.37 19.50 19.70 19.75 19.44 20.15 — 19.41

The increase includes approximately R72 million which is attributable to translation. This was offset by gold in-process which decreased R169 million year on year due to the lower production during the last quarter of the 2020 financial year as well as the plants being cleaned out during the South African COVID-19 national lockdown. (b) The consumables’ balance increased R298 million year on year, primarily as a result of the impact of the weakening of the Rand against the Australian dollar from R9.91 /A$1 at 30 June 2019 to R11.96 /A$1 at 30 June 2020 and the resultant movement when translating the balance for the Hidden Valley operations at year-end.

Equity share-based payments are measured at the fair value of the equity instruments at the grant date and are expensed over the vesting period, based on the group’s estimate of the shares that are expected to vest. Refer to note 34 for more details. (d) The actuarial gains or losses related to the post-retirement benefit obligation will not be reclassified to the income statement.

The excess of the purchase price of R579 million over the carrying amount of non-controlling interest acquired, amounting to R381 million , has been accounted for under other reserves. (f) On 24 May 2004, the group issued a convertible bond. The amount representing the value of the equity conversion component is included in other reserves, net of deferred income taxes. The equity conversion component is determined on the issue of the bonds and is not changed in subsequent periods. The convertible bonds were repaid in 2009. 24 OTHER RESERVES continued (g) On 19 March 2010, Harmony Gold Mining Company Limited concluded an agreement with African Vanguard Resources (Proprietary) Limited (AVRD), for the purchase of its 26% share of the mining titles of the Doornkop South Reef. The original sale of the 26% share in the mining titles was accounted for as an in-substance call option by AVRD over the 26% mineral right. The agreement to purchase AVRD's 26% interest during the 2010 financial year was therefore considered to be a repurchase of the option (equity interest). The 26% interest was transferred from AVRD to Harmony in exchange for Harmony repaying the AVRD Nedbank loan and the issue of 2 162 359 Harmony shares. The difference between the value of the shares issued of R152 million , the liability to the AVRD and transaction costs, have been taken directly to equity. (h) Includes R106 million (2019: R82 million ) related to the fair value movement of Harmony's interest in Rand Mutual Assurance. Refer to note 17 .

Schedule of Financial Assets Measured at Fair Value	The following table sets out the group’s assets and liabilities measured at fair value by level within the fair value hierarchy: SA Rand Figures in million At 30 June 2020 At 30 June 2019 Level 2 Level 3 Level 2 Level 3 Fair value through other comprehensive income Other non-current assets (a) — 77 — 59 Fair value through profit or loss Restricted investments (b) 837 — 1 256 — Derivative financial assets (c) 68 — 506 — Derivative financial liabilities (c) (5 003 ) — (422 ) — Loan to ARM BBEE Trust (d) — 306 — 271 (a) The increase in level 3 fair value measurement relates to the equity investment in Rand Mutual Assurance previously carried at cost. The fair value of the investment was estimated with reference to an independent valuation. A combination of the "Embedded Valuation" and "Net Asset Value" techniques were applied to revalue the investment as at 30 June 2020. In evaluating the group's share of the business, common practice marketability and minority discounts as well as additional specific risk discounts were applied. (b) The majority of the balance is directly derived from the Top 40 index on the JSE, and is discounted at market interest rate. This relates to equity-linked deposits in the group's environmental rehabilitation trust funds. The balance of the environmental trust funds are carried at amortised cost and therefore not disclosed here. (c) The mark-to market remeasurement of the derivative contracts was determined as follows: • Foreign exchange contracts comprise of zero cost collars and FECs: The zero cost collars were valued using a Black-Scholes valuation technique derived from spot Rand/US$ exchange rate inputs, implied volatilities on the Rand/US$ exchange rate, Rand/US$ inter-bank interest rates and discounted at market interest rate (zero-coupon interest rate curve). The value of the FECs is derived from the forward Rand/US$ exchange rate and discounted at market interest rate (zero-coupon interest rate curve). • Rand gold contracts (forward sale contracts): spot Rand/US$ exchange rate, Rand and dollar interest rates (forward points), spot US$ gold price, differential between the US interest rate and gold lease interest rate which is discounted at market interest rate. • US$ gold contracts (forward sale contracts): spot US$ gold price, differential between the US interest rate and gold lease interest rate and discounted at market interest rate. • Silver contracts (zero cost collars): a Black-Scholes valuation technique, derived from spot US$ silver price, strike price, implied volatilities, time to maturity and interest rates and discounted at market interest rate. (d) The increase in level 3 fair value measurement relates to the ARM BBEE loan that was carried at amortised cost prior to 1 July 2018. Refer to note 17 . The fair value was calculated using a discounted cash flow model taking into account projected interest payments and the projected share price for African Rainbow Minerals Limited (ARM) on the expected repayment date. A 10% change in the discount rate of 9.8% would not cause a material change to the fair value of the loan. The fair value of the loan balance is limited to the sum of the capital amounts plus cumulative interest not paid, being R316 million .
