ASSURANCE REPORT

INDEPENDENT ASSURANCE REPORT TO THE DIRECTORS OF HARMONY GOLD MINING COMPANY LIMITED

We have been engaged by the directors of Harmony Gold Mining Company Limited ("Harmony" and/or the "Company") to perform an independent assurance engagement in respect of Selected Sustainability Information reported in the Company’s Integrated Annual Report for the year ending 30 June 2014 (the "Report"). This report is produced in accordance with the terms of our contract with the Company dated 7 April 2014.

INDEPENDENCE AND EXPERTISE

We have complied with the International Federation of Accountants’ (IFAC) Code of Ethics for Professional Accountants, which includes comprehensive independence and other requirements founded on fundamental principles of integrity, objectivity, and professional competence and due care, confidentiality and professional behaviour. Our engagement was conducted by a multi-disciplinary team of health, safety, environmental and assurance specialists with extensive experience in sustainability reporting.

SCOPE AND SUBJECT MATTER

The subject matter of our engagement and the related levels of assurance that we are required to provide are as follows:

Reasonable assurance

The following Selected Sustainability Information in the Report was selected for an expression of reasonable assurance:

• Electricity purchased (kWh) (how we performed)
• Total Scope 2 carbon emissions (tCO₂e) (how we performed)
• Preferential procurement – black economic empowerment total spend (South African Rands) (how we performed)

Limited assurance

The following Selected Sustainability Information in the Report was selected for an expression of limited assurance:

• Housing and living conditions – % conversion (how we performed)
• Local Economic Development (LED) spend (South African Rands) (how we performed)
• Water used for primary activities (kilolitres) (how we performed)
• Volume of mineral waste disposed (tonnes) (how we performed)
• Lost Time Injury Frequency Rate (lost-time injury frequency rate) (how we performed)
• Silicosis – number of cases confirmed in the 2014 reporting period (how we performed)
• Critical skills training – number of people trained in the 2014 reporting period (how we performed)
• Employment equity in management in South Africa (%) (how we performed)
• Total Scope 1 carbon emissions (tCO₂e) (how we performed)
• Total Scope 3 carbon emissions (tCO₂e) (how we performed)

We refer to this information as the "Selected Sustainability Information for Reasonable Assurance" and the "Selected Sustainability Information for Limited Assurance", respectively, and collectively as the "Selected Sustainability Information".

We have not carried out any work on data reported for prior reporting periods, nor have we performed work in respect of future projections and targets. We have not conducted any work outside of the agreed scope and therefore restrict our opinion to the Selected Sustainability Information.

RESPECTIVE RESPONSIBILITIES OF THE DIRECTORS AND PricewaterhouseCoopers INC.

The directors are responsible for selection, preparation and presentation of the Selected Sustainability Information in accordance with the criteria set out in the Company’s internally defined procedures and captured in the glossary of terms, (referred to as the "Reporting Criteria"), and for the development of the Reporting Criteria. The directors are also responsible for designing, implementing and maintaining of internal controls as the directors determine is necessary to enable the preparation of the Selected Sustainability Information that are free from material misstatements, whether due to fraud or error.

Our responsibility is to form an independent conclusion, based on our reasonable assurance procedures, on whether the Selected Sustainability Information for Reasonable Assurance has been prepared, in all material respects, in accordance with the Reporting Criteria.

We further have a responsibility to form an independent conclusion, based on our limited assurance procedures, on whether anything has come to our attention to indicate that the Selected Sustainability Information for Limited Assurance has not been prepared, in all material respects, in accordance with the Reporting Criteria.

This report, including the conclusion, has been prepared solely for the directors of the Company as a body, to assist the directors in reporting on the Company’s sustainable development performance and activities. We permit the disclosure of this report within the Report for the year ended 30 June 2014, to enable the directors to demonstrate they have discharged their governance responsibilities by commissioning an independent assurance report in connection with the Report. To the fullest extent permitted by law, we do not accept or assume responsibility to anyone other than the directors as a body and the Company for our work or this report save where terms are expressly agreed and with our prior consent in writing.

ASSURANCE WORK PERFORMED

We conducted our assurance engagement in accordance with International Standard on Assurance Engagements 3000: Assurance Engagements other than Audits and Reviews of Historical Financial Information (ISAE 3000), and, in respect of greenhouse gas emissions, International Standard on Assurance Engagements 3410: Assurance Engagements on Greenhouse Gas Statements (ISAE 3410), issued by the International Auditing and Assurance Standards Board. These standards require that we comply with ethical requirements and that we plan and perform the assurance engagement to obtain either reasonable or limited assurance on the Selected Sustainability Information as per the terms of our engagement.

Our work included examination, on a test basis, of evidence relevant to the Selected Sustainability Information. It also included an assessment of the significant estimates and judgements made by the directors in the preparation of the Selected Sustainability Information. We planned and performed our work so as to obtain all the information and explanations that we considered necessary in order to provide us with sufficient evidence on which to base our conclusion in respect of the Selected Sustainability Information.

Our work in respect of the Selected Sustainability Information for Reasonable Assurance included the following procedures:

• reviewing the processes that Harmony have in place for determining the Selected Sustainability Information included in the Report;
• obtaining an understanding of the systems used to generate, aggregate and report the Selected Sustainability Information;
• conducting interviews with management at corporate head office;
• evaluating the data generation and reporting processes against the Reporting Criteria;
• performing key controls testing and testing the accuracy of data reported on a sample basis; and
• reviewing the consistency between the Selected Sustainability Information and related statements in Harmony’s Report

Our procedures relating to the Selected Sustainability Information for Limited Assurance primarily comprised:

• reviewing the processes that Harmony have in place for determining the Selected Sustainability Information included in the Report;
• obtaining an understanding of the systems used to generate, aggregate and report the Selected Sustainability Information;
• conducting interviews with management at corporate head office;
• evaluating the data generation and reporting processes against the Reporting Criteria;
• performing key controls testing and testing the accuracy of data reported on a sample basis; and
• reviewing the consistency between the Selected Sustainability Information and related statements in Harmony’s Report

A limited assurance engagement is substantially less in scope than a reasonable assurance engagement under ISAE 3000. Consequently, the nature, timing and extent of procedures for gathering sufficient appropriate evidence are deliberately limited relative to a reasonable assurance engagement, and therefore less assurance is obtained with a limited assurance engagement than for a reasonable assurance engagement.

The procedures selected depend on our judgement, including the assessment of the risk of material misstatement of the Selected Sustainability Information, whether due to fraud or error. In making those risk assessments, we consider internal control relevant to the Company’s preparation of the Selected Sustainability Information in order to design procedures that are appropriate in the circumstances.

We believe that the evidence we have obtained is sufficient and appropriate to provide a basis for our conclusions.

INHERENT LIMITATIONS

Non-financial performance information is subject to more inherent limitations than financial information, given the characteristics of the subject matter and the methods used for determining, calculating, sampling and estimating such information. The absence of a significant body of established practice on which to draw allows for the selection of different but acceptable measurement techniques which can result in materially different measurements and can impact comparability. Qualitative interpretations of relevance, materiality and the accuracy of data are subject to individual assumptions and judgements. The precision of different measurement techniques may also vary. Furthermore, the nature and methods used to determine such information, as well as the measurement criteria and the precision thereof, may change over time. It is important to read the Report in the context of the Reporting Criteria.

In particular, where the information relies on factors derived by independent third parties, our assurance work has not included examination of the derivation of those factors and other third party information.

CONCLUSIONS

Reasonable assurance

Based on the results of our reasonable assurance procedures, in our opinion, the Selected Sustainability Information for the year ended 30 June 2014, has been prepared, in all material respects, in accordance with the Reporting Criteria.

Limited assurance

Based on the results of our limited assurance procedures nothing has come to our attention that causes us to believe that the Selected Sustainability Information for the year ended 30 June 2014, has not been prepared, in all material respects, in accordance with the Reporting Criteria.

Other Matters

The maintenance and integrity of Harmony’s website is the responsibility of Harmony’s directors. Our procedures did not involve consideration of these matters and, accordingly we accept no responsibility for any changes to either the information in the Report or our independent assurance report that may have occurred since the initial date of presentation on the Harmony website.
