Appendix to the Updated Wafi-Golpu Feasibility Study

Johannesburg, Thursday, 12 April 2018. Harmony Gold Mining Company Limited (Harmony) hereby releases an appendix to the announcement “Updated Wafi-Golpu Feasibility Study” released on 19 March 2018. This release includes the JORC Code 2012 Edition – Table 1 which underpins the Golpu Mineral Resource and Ore Reserve. The updated production target which is planned to be mined is based solely on the Probable Ore Reserves.

Golpu Mineral Resource

The Mineral Resources for Golpu Project remain unchanged from the release titled “Golpu feasibility study confirms robust investment case” dated 15 February 2016 (the original release). Harmony confirms that it is not aware of any new information or data that materially affects the information included in the original release in regard to Mineral Resources, and that all material assumptions and technical parameters underpinning the Mineral Resource estimate in the original release continue to apply and have not materially changed. Harmony confirms that the form and context in which the Competent Person’s findings are presented have not been materially modified from the original release.

Mineral Resources are reported inclusive of Ore Reserves.

Golpu Ore Reserve

As stated in the market release “Updated Wafi-Golpu Feasibility Study” dated 19 March 2018, the Feasibility Study Update Ore Reserve is estimated to contain 5.5 million ounces of gold and 2.5 million tonnes of copper (Harmony’s 50% interest). This estimate is materially in line with previous estimates and reflects updated long term cost and metal price assumptions and optimised designs in the Golpu Feasibility Study Update (refer Golpu Ore Reserve Table below).

About the Wafi-Golpu Project

Harmony and Newcrest each currently own 50% of Wafi-Golpu through the WGJV.

The State of PNG retains the right to purchase, at a pro rata share of accumulated exploration expenditure, up to 30% equity interest in any mineral discovery at Wafi-Golpu, at any time before the commencement of mining. If the State of PNG chooses to take-up its full 30% interest, the interest of each of Newcrest and Harmony will become 35%.

The Golpu deposit is located approximately 65km south-west of Lae in the Morobe Province of PNG which is the second largest city in PNG and will host the Wafi-Golpu export facilities. The proposed mine site sits at an elevation of approximately 200 metres above sea level in moderately hilly terrain and is located near the Watut River approximately 30km upstream from the confluence of the Watut and Markham rivers.
