Harmony Gold Mining Company Limited
(Harmony), a world-class gold mining
and exploration company, has
operations and assets in South Africa
and Papua New Guinea. Harmony,
which has more than 60 years’
experience in the industry, is the third
largest gold producer in South Africa.
Our assets include 9 underground
mines and 1 open pit operation and
several surface sources in South Africa.
Our assets in PNG – an open pit mine
(Hidden Valley), as well as the
significant Golpu project – are held in a
joint venture. We also own several
exploration tenements, in Papua New
Guinea.
The company’s primary stock exchange
listing is on the JSE with a secondary
listing on the New York Stock
Exchange. The bulk of our shareholders
are in South Africa and the United
States. Additional information on the
company is available on the corporate
website, www.harmony.co.za.
Golpu feasibility study confirms robust investment case
· High grades, early cash flow
· Staged development with future optionality and flexibility
· Robust returns
· Lowest quartile costs for copper
· Significant attributable annual production for Harmony at approximately 500 000
gold equivalent ounces per year during peak production
Johannesburg: Monday, 15 February 2016. Harmony Gold Mining Company
Limited (“Harmony”) is pleased to announce the results of the Golpu Stage 1
Feasibility
1
and Stage 2 Prefeasibility studies and declare updated Resources and
Reserves for the Golpu project. Both studies have confirmed a robust investment
case – one that supports proceeding with the project
“The Golpu porphyry is a world-class resource due to its size, high grades, long-life
and low operating costs. The design of the mine allows optionality and flexibility to
scale the operation up with a relatively low capital investment in response to
increasing commodity prices. Golpu is part of Harmony’s future and will create value
for our shareholders in the long term”, says Harmony chief executive officer, Peter
Steenkamp.
The Stage 1 project capital on a 100% basis is estimated at US$2.6bn, yielding an
internal rate of return of 16%. The Stage 1 Feasibility study justifies the development
of twin exploration access declines, with two proposed block caves designed to
extract approximately 50% of the contained metal (gold and copper) of the Golpu
reserve. The approximately 50% remaining reserve is to be extracted by a deeper
block cave (BC3) below block cave 2 (Stage 2). The common path mining and
processing infrastructure of Stage 1 will be utilised in support of the development of
Stage 2.
Engagement with key stakeholders, including the PNG national government, the
Morobe provincial government, landowners and community representatives continues
so as to ensure clear alignment on the project objectives.

Key findings of the feasibility study2
·    Low operating costs will withstand low commodity price cycles and will benefit from high returns in higher commodity
price cycles
·    The updated Ore Reserve as at 31 December 2015, is estimated to contain 5.5 million ounces of gold and 2.4 million
tonnes of copper (Harmony’s 50% interest)
·    Project de-risked, with no significant deviation from the Stage 1 prefeasibility study economic outcomes and technical
recommendations
·    Golpu is amenable to “staged development”
-    allows for optimising the capital efficiency
-    progressively de-risks the project prior to further investments
·    Financial metrics3 of Stage 1:
-
Net present value (NPV): US$1.1bn
-
Internal rate of return (IRR): ~16%
-
Maximum negative free cash flow (100% basis): US$1.8bn
·    Stage 1 targets higher-grade sections of the deposit thereby optimising free cash flow.
·    The development of the near surface block cave 1 (BC1), as part of Stage 1, affords early cash flow thereby reducing
the maximum negative cash outflow
·    Block caving is the preferred mining method for the following reasons:
-
ore body geometry and indicative rock mass characteristics are suited to block caving
-
it is a high productivity, low operating cost underground mining method
·    The Golpu Stage 2 Prefeasibility study focused on optimising Stage 1 and then expanding block cave 2 (BC2)
throughput before the establishment of a third block cave (BC3) below BC2
·    The project is located in close proximity to the City of Lae with established infrastructure such as roads, marine port,
airport, and light industry
·    Studies conducted by WorleyParsons (South Africa) and other consultants under direct management of the joint
venture project team
-    more than 460 000 man hours worked on the latest studies
GOLPU STAGE 1 FEASIBILITY STUDY2
Stage 1 of the development of Golpu focuses on the development of two block caves, BC 1 and BC 2 and all associated
infrastructure required. A third block cave, BC 3 is contemplated in Stage 2.

The operating cost estimate covers all the operating expenditure to mine, treat and administer extraction of the orebody,
as well as transporting, dewatering and ship-loading of the concentrate at the Port of Lae. Cash cost and total
production costs include treatment and refining charges, freight to end customers, royalties and mining levies. Total
production cost includes sustaining and construction capital costs. The realisation cost estimate in the financial model
equals U$17.61/t, this includes treatment and refinery costs, concentrate transport and handling costs, and royalties and
is not included in the total operating cost. Any real, above inflation, price escalation of costs to the time of forecast
expenditure has been excluded. Costs are however sourced and forecast in the underlying currency in which they are
incurred.

The project will only progress into execution upon the grant of a Special Mining Lease (SML) which will include all
necessary permits, approvals and consents required from the Papua New Guinea Government, landowners and other
relevant stakeholders. Assuming all such approvals are obtained, the development timeline outlined in the Stage 1
feasibility study is set out below.
Schematic 2: Development timeline
If signed prior to the grant of a SML, approval will be sought from the Boards of both Wafi Golpu joint venture parties to
bring forward the advanced exploration work and earthworks for establishment of the access declines. Advanced
exploration via underground access will afford an opportunity to obtain further data at depth and as a result, a revisit of
the current proposed Stage 1 base case capital profile, schedule and execution approach.
Further work on the Stage 1 Feasibility study
As planned the following areas will be the focus of further assessment to optimise the study outcomes and the
incorporation of additional data which will be collected in the next study phase.
Access declines: Declines towards the orebody affording drilling platforms is required in order to verify geotechnical and
hydrological interpretations of the orebody at depth
background image
Page

of
12
Geotechnical interpretation: Further underground drilling and mapping work is required to confirm assumptions of the
rock mass characteristics in each cave and the rock mass response to the changing stress regime.
Tailings management: Further assessment of tailings disposal options
Hydrology: The management of water will be central to the success of the mining operation, primarily due to the nature
of the geological environment of the project site. Further investigation and modelling of water will focus on increasing the
confidence in the geohydrology model by obtaining additional data from drilling campaigns, modelling the effectiveness
of a dewatering bore field around the block cave subsidence zone, and streamflow and surface hydrology modelling and
management
Permitting and environmental approvals: Work will continue with the PNG Government to obtain statutory environmental
approvals and other regulatory permits for the project
Port and power: Further assessment of optimal arrangements for port facilities and power supply
Community engagement
In parallel with further technical studies and project definition, the local communities will be actively engaged and
appraised of the project development roadmap and next steps. In the December 2015 quarter, 90 meetings attracting
2,756 local community participants were held. The three major communities involved are the Hengambu, Yanta and
Babuaf spread over 15 villages in the region. The local communities remain supportive of the project.
Capital costs
Harmony’s share (50%) of the estimated capital requirements for Stage 1 from grant of the Special Mining Lease are
approximately as follows:

GOLPU STAGE 2 PREFEASIBILITY STUDY
The Stage 2 pre-feasibility study was conducted in parallel to the Stage 1 feasibility study. The first step of Stage 2
looked at debottlenecking the 6Mtpa capacity from Stage 1 BC2. The debottlenecking increased the production capacity
to 7Mtpa by making minor and low cost modifications to the process plant grinding circuit and the underground material
handling system. (Stage 2-1)
The access declines to the block caves in both the Stage 1 feasibility study and Stage 2 pre-feasibility study were
treated as common path access imbedding optionality and flexibility in the designs to scale the operation up with a
relatively low capital investment in response to increasing commodity prices.
The second step for Stage 2 is increasing the mine’s production rate. By optimising all existing Stage 1 infrastructure
and increasing the size of the underground loader fleet a higher mining production output from BC2 can be achieved,
without a significant capital investment. A second process plant with a capacity of 7Mtpa will be constructed to bring
total plant capacity to 14mtpa. (Stage 2-2)
The third and final stage investigated by the pre-feasibility study for Stage 2 was to extend the life of the operation with
the construction of a third block cave below BC2. Additional capital is required to extend the decline access and
conveyor belt system, the ventilation system and establish the associated underground infrastructure (Stage 2-3).

RESOURCE AND RESERVE UPDATE (100%)
Mineral Resource
The Golpu Mineral Resource has been updated as at 31 December 2015 to align with the results of Golpu 2015 Stage 1
feasibility study and Stage 2 (Life-of-Mine) prefeasibility study. The key change is the applied cut-off grade that defines
background image
Page

the volume with reasonable prospects of eventual economic extraction. The Golpu Mineral Resource is constrained
within a marginal breakeven shell using WGJV 2015 gold and copper revenues and the estimated long term cost
structure developed in the 2015 Golpu Stage 2 PFS. The December 2014 Mineral Resource was reported within a 0.2%
Cu shell representative of the revenue and cost structures of the 2012 Golpu PFS. There has been no additional drilling
in 2015 that impacts the Golpu mineralised volume and the underlying geology and grade model is unchanged from that
used in the December 2014 Mineral Resource.
