//
Through 2018,  
OZ Minerals’ 
organisational structure 
has evolved for growth. 
We’ve refined our 
strategy; strengthened 
and simplified 
governance processes; 
and reorganised the 
team to support the 
forward momentum. 

Message from the Chairman and CEO 

Innovation and agility 
We have implemented many changes to the 
culture and wider stakeholder relationships over 
the past years and there will be more to come  
as the company grows. 

We are determined to do things better and 
innovate: 

 / Prominent Hill built up its data management 
and analysis capabilities and is investigating 
how big data could be captured and stored by 
embedding wireless technology throughout its 
surface operations. 

 / We investigated opportunities to increase 

Prominent Hill’s production to above 3.5 million 
to four million tonnes per year once stockpiles 
are exhausted in 2023. 

 / At Carrapateena, the innovative approach 
used to develop community and business 
partnerships continued to yield positive 
outcomes; the Carrapateena team, together 
with Global Maintenance Upper Spencer Gulf, 
was a joint recipient of the South Australian 
Premier’s Award for Excellence in Working  
with Communities. 

 / At West Musgrave we worked with PwC – The 
difference to develop a new, effective, inclusive 
and accelerated style of working on the project. 

Partnering with our communities 
In 2018, we embarked on developing a flagship 
social contribution project under the banner 
Educating the Next Generation. We are in the 
early stages of developing partnerships with  
The Smith Family and the Clontarf Foundation. 

The three-year education support program will 
create value for the communities where we 
operate, build enduring partnerships aligned 
with the community’s aspirations, and provide 
engagement opportunities for our employees. 
Importantly, the flagship banner, Educating the 
next Generation, is internationally applicable.

Rewarding our shareholders 
As a result of our strong performance in 2018, 
the Board declared a total, fully-franked dividend 
for 2018 of 23 cents per share, made up of a half 
year payment of eight cents per share and an 
end-year payment of 15 cents. 2018 earnings per 
share totalled 71.5 cents. 

Our updated capital management strategy 
prioritises shareholder returns while supporting 
our growth ambitions. 

Dear shareholders, 

Realising our growth strategy  
in a changing world 
This year we safely and significantly advanced our 
growth strategy, having prepared the company 
for growth over the preceding three years. 
We reached or exceeded the production and 
cost guidance at Prominent Hill and advanced 
Carrapateena, our copper–gold project in South 
Australia, with final government approvals 
in March 2018 triggering the second stage 
of construction. We have taken the first step 
towards becoming a global copper core modern 
mining company with the successful acquisition 
of Avanco Resources, an Australian-based 
company with an operating asset and a number 
of advanced exploration projects in Brazil, giving 
us a foothold in two highly prospective provinces, 
Carajás and Gurupi. We continued to evolve  
OZ Minerals’ exploration pipeline with new sites  
in Sweden and Peru.

A good balance sheet supported by strong 
financial results led to a $677.3 million  
investment into growth activities; $67.6 million  
in dividends to shareholders; and a cash balance  
of $505.0 million. 

Strengthening the leadership  
and structure
Through 2018, OZ Minerals’ organisational 
structure has evolved for growth. We’ve refined 
our strategy; strengthened and simplified 
governance processes; and reorganised the team 
to support the forward momentum. The refreshed 
strategy will deliver a continued push to innovate 
and create value. 

Safety is core to OZ Minerals and it is an 
integral part of everything we do. Our overall 
total recordable injury frequency rate was 7.52 
compared to 6.39 in 2017, partially reflecting the 
change and rapid growth of activity during 2018 
with the construction of a new mine and projects 
now in multiple countries. Safety improvement 
focussed initiatives are being stepped up in 2019. 

The devolved organisational structure has 
enabled us to integrate the new Brazilian assets 
while retaining a strong focus on operating 
the Prominent Hill mine and building the 
Carrapateena project. The company’s strategy and 
activities are managed by an executive team with 
experience in larger, more complex companies 
and international operations. 

The OZ Minerals Board has the breadth and depth 
of experience to navigate us through a future 
with global operations. Two new directors recently 
joined the Board. Charlie Sartain and Marcelo 
Bastos bring extensive international copper mining 
experience to the team – both directors have 
also worked at senior levels of large international 
mining companies in South America.

2019 priorities 
The outlook for copper remains optimistic with 
demand for traditional and new uses of copper 
contributing to a projected growth in demand. 
A global mine supply shortfall is projected in the 
coming years due to declining head grades and 
a lack of new mine development. This, combined 
with emerging technology which depends on 
copper, suggests that it will remain a sought- 
after commodity.

In 2019, we will deliver value for shareholders  
and other stakeholders – employees, 
communities, governments and suppliers – by: 

 / strengthening our approach to safe work  

and further embedding it in our operations 

 / fostering innovation and collaboration in  
the business and developing a modern  
mining culture

 / reliably and consistently delivering Prominent 

Hill’s mine plan and seeking ways to extend its 
life so that it continues to support future growth 

 / commissioning Carrapateena on schedule  

for Quarter 4 2019

 / optimising plans to develop our Brazilian assets  

 / completing the pre-feasibility study for West 
Musgrave, our copper nickel project with  
Cassini Resources in Western Australia 

 / developing a ‘phase two’ expansion plan  

for Carrapateena

 / maintaining the future growth pipeline  

through a province approach and seeking 
acquisitions that provide foot-holds into  
priority mineralised belts. 

Our achievements of today and tomorrow  
would not be possible without the support  
of our shareholders, customers, partners, 
communities and our people. We thank you  
for your support and are pleased to lead  
OZ Minerals on the journey towards becoming  
a modern mining company.

We refined our strategy in 2018 and kept the focus on creating stakeholder value in 
ways consistent with the How We Work Together principles. Delivering to strategy 
through 2018 saw us moving to realise our vision of becoming a global copper-
core modern mining company that delivers superior value across multiple operating 
assets with diverse operations and project pipeline. 

Creating value is at the heart of our strategy. It means creating value for all of our 
stakeholders – shareholders, employees, communities, governments and our supply 
partners. This concept of value creation has been embedded into our governance 
system through our process standards and how we assess risk. 

Lean and innovative 
Running a lean business encourages our people 
to find new and better ways to work, as we 
innovate to deliver bottom-half cost curve and 
superior production performance. We embrace 
new ideas and new thinking and are willing to be 
the first to try something which might add value. 
We test ideas safely and efficiently, fail fast and 
look beyond our own industry for inspiration. 
In 2018, we simplified our process standards to 
complement our governance system and ensure 
high compliance standards. The simplified process 
standards allow our assets to adapt to their local 
conditions and encourage our employees to use 
their innate skills, be curious and innovate. 

Customer focus 
We provide a quality product based on our 
customers’ needs and market demand. Our 
people know our customers well and we want  
to be partners to their businesses. 

How We Work Together 
Our How We Work Together principles are the 
glue that binds our company. Our people use the 
principles to create an inclusive culture that drives 
diversity and results in superior performance. We 
work safely, unlock innovation, embrace change 
and consistently deliver. 

Winning the 2018 Premier’s Award for Excellence 
in Working with Communities acknowledges 
how our How We Work Together principles have 
been leveraged to generate shared value for our 
community stakeholders.

Global copper 
Our acquisition of Avanco Resources Limited, 
which has an operating asset and projects in 
Brazil, delivers on our strategy of developing a 
global portfolio of copper assets. The acquisition 
immediately added to our copper production 
profile and provided us with expansion options in 
the highly prospective Carajás iron-oxide–copper–
gold province and Gurupi Greenstone Gold Belt 
in Brazil, enhancing our portfolio at every stage of 
the asset pipeline. 

Capital discipline 
We responsibly use shareholder funds for long 
term success, only spending on things we 
need and that represent the best value. Capital 
discipline is applied across all our projects, 
regardless of their stage, and we continue to look 
for opportunities to reduce costs where we can.

Having a strong balance sheet gives flexibility 
and agility. We chose to fund the acquisition of 
Avanco partly with scrip, to maintain a strong 
balance sheet through the development of 
Carrapateena, and to give flexibility for the future.

We updated our capital management strategy 
in 2018 to prioritise shareholder returns while 
supporting our growth strategy and maintaining  
a disciplined approach to capital allocation. 

Devolved and agile 
A devolved organisational model is an important 
enabler of our strategy and allows us to efficiently 
bring more assets into the company from 
different parts of the world or potentially exit 
assets in future. Our assets remain autonomous 
and accountable, while the corporate centre 
undertakes work on strategy; customers and 
owners; assurance; and growth. Our devolved 
model unlocks discretionary effort and value, 
as our people are accountable and encouraged 
to collaborate to make better and more agile 
decisions. During the year, we reorganised our 
Executive Committee team’s areas of responsibility 
so we can continue to be flexible and scalable as 
our business grows.

Prominent Hill

Prominent Hill is a copper–gold–silver 
mine located in South Australia,  
130 km south-east of Coober Pedy.

Prominent Hill continues to deliver 
consistent and reliable results, meeting 
copper production and cost guidance for 
the fourth consecutive year. Prominent 
Hill generated $522.0 million in free 
cash and enables our growth activities. 

Highlights for 2018
 / We achieved cost guidance and annual  

copper and gold production. 

 / The mine life was extended to 2030. 

 / The open pit mine was safely closed after more 
than 100 Mt of ore was mined over 10 years.

 / We successfully transitioned the mine to an 

underground-only operation.

 / We completed the third and fourth 

underground declines, enabling a ramp up  
in 2019.

 / Operational efficiencies increased as we 

commissioned surface fleet rehandling activities.

 / We began a mine expansion study, with  

drilling expected to begin in Quarter 1 2019.

 / Construction of a new transmission line  

commenced.

 / Our mine-to-mill modelling software was 

upgraded to improve scenario analysis capability 
and facilitate faster operational decision-making 
and improved strategic planning.

Safe, consistent and  
reliable operations
Prominent Hill’s transition to an underground-only 
mining operation was completed in early 2018. 

Thiess Mining, the contractor for open pit mining 
at Prominent Hill, was awarded a five-year 
contract to provide run-of-mine management, 
crusher feed and ore-rehandling services. 

Underground mining will ramp up to 3.7-4.0 Mtpa1 
in 2019 as the third and fourth declines were 
completed during the year. The plant at Prominent 
Hill will remain at full capacity until mid-2023, 
supplemented by ore from the open pit stockpiles. 

In early 2018, a power strategy was developed 
for our South Australian assets. The first phase 
included the development of a transmission line, 
which is being constructed under a build, own, 
operate, and maintain agreement with ElectraNet. 
Construction will commence in 2019 and the 
transmission line is expected to be operational  
in mid-2020.   

0 8

Safety is a core value at Prominent Hill. The  
TRIFR for 2018 was 5.78, which was higher 
than the previous year. Safety of our people 
will continue to be a key focus for Prominent 
Hill through our safety leadership, our systems 
of work, and our workplace attitudes where all 
employees and contractors take action to ensure 
effective controls that address hazards are in 
place. Key initiatives included: 

 /

implementing collaborative safety training  
with the South Australian ambulance service

 / undertaking a nationally recognised 

auditor training course to effectively audit 
site compliance against the OZ Minerals 
performance standards and embrace best 
practice initiatives

 / developing skills for Prominent Hill’s  
emergency response team through  
participation in the South Australian Mines 
Emergency Rescue competition

 / commencing a behavioural safety program  
to support safety leadership and a strong  
safety culture aligned to organisational values

 / establishing a site-based health and  

wellbeing centre for physiotherapy and 
counselling services.

Working in the community 
Creating value for our stakeholders is an enduring 
priority at Prominent Hill. In 2018, we developed 
a partnership with the local Coober Pedy Area 
School to support and mentor young people in 
the local area. 

We also worked together with Global 
Maintenance Upper Spencer Gulf and the  
State Government’s Industry Capability Network 
to encourage local businesses to participate in  
our operations. 

Our focus in 2019 is to: 
 / consistently deliver strong results with C1  
costs in the bottom half of the cost curve 

 / construct the Malu Paste Plant. This will 

replace the Cemented Hydraulic Fill Plant and is 
scheduled to be completed in Quarter 4 2019

 / progress internal mining studies to investigate 
options for delivering higher value mine plans. 
This includes the Prominent Hill expansion study 
where drilling is to commence in early 2019

 / complete a feasibility study on haulage options

 / steadily ramp up underground mining to 

3.5–4.0 Mtpa1

 / complete gold-only ore processing trials with  
a view to test recoveries and mill throughput.

//
The Prominent Hill 
mine has achieved 
copper guidance for 
four consecutive years. 
It continues to generate 
value through strong 
operational discipline 
and consistent, safe, 
and cost effective 
production.

Carrapateena is an iron-oxide–copper–gold (IOCG)
deposit located in the highly prospective Gawler 
Craton in South Australia. The project is one of 
Australia’s largest new mining developments and 
has an estimated mine life of 20 years. 

Highlights for 2018
 / We received all primary and secondary approvals.

 / Phase one of construction began and was 

completed, including the aerodrome, airstrip 
and accommodation village. 

 / Phase two construction began, which includes 
the minerals processing plant, non-processing 
infrastructure, the tailings storage facility and 
installation of the communications network.

 / The team received the Premier’s Award for 
Excellence in Working with Communities.

 / Underground development rates remained on 
schedule because of a smooth transition to the 
new underground mining contractor.

 / The total decline development reached over 

10,600 m at the end of January 2019.

 / We strengthened relationships with the local 

community, pastoralists and traditional owners.

 / Key leadership appointments were made in line 

with the operational readiness plan.

Construction of the minerals processing plant 
was brought forward as part of an optimised 
development strategy. We also improved safety 
and commenced the upgrade of the existing 
southern access road in line with this strategy. 
Tailings storage facility construction was deferred 
until Quarter 4 2018 and construction of the 
western access road was deferred until 2020.

Safety focus
Safety is a core value for the project across 
operational and construction teams. In 2018 the 
TRIFR was 7.52, an improvement on the previous 
year. The team implemented the Stand Together 
for Safety initiative, which saw contract partners 
and the project team align safety messaging and 
activities across the site. 

Working in the community
We have continued our commitment to further 
developing partnerships with the local community, 
pastoralists and traditional owners. 

More than 40 local businesses have delivered 
work for the project through a partnership with 
the Global Maintenance Upper Spencer Gulf and 
Industry Capability Network, that is designed to 
maximise local industry and business participation. 

The Partnering Management Committee, made 
up of members of the Carrapateena team and  
the Kokatha Aboriginal Corporation, continues  
to meet on a quarterly basis to operationalise  
the Native Title Mining Agreement. 

Land access agreements with pastoralists from 
surrounding properties have been successfully 
negotiated. A number of community roadshows 
were also held throughout the year to update  
the local community on the project’s progress. 

Our focus for 2019 is to: 
 / commission and have first concentrate  

by Quarter 4 2019

 / hand over the project from construction  

to operations in Quarter 4 2019

 /

install the underground materials  
handling system

 / complete improvements to the southern  

access road 

 / complete construction of all five surface  

vent shafts

 / energise the powerline and substation  

onsite in Quarter 2 2019

 / continue expansion studies. 

Carrapateena province expansion
Carrapateena expansion studies started in 2018 
and were focused on optimising the Carrapateena 
resource and ‘life of province’ planning. These 
studies investigated how to optimise the sub-level 
cave inventory (a possible block cave transition for 
the lower half of the Carrapateena resource) and 
included options for mining nearby lower grade 
mineralised zones. Study outcomes are expected 
to be available in Quarter 1 2019.

In 2018, we undertook resource delineation 
programs at the Fremantle Doctor and Khamsin 
prospects which returned broad intersections of 
mineralisation and extended grade outside of the 
previously modelled mineralised domains.

Four holes were drilled at Fremantle Doctor, all 
of which returned intersections of chalcopyrite-
dominant copper mineralisation. The recent 
drilling was incorporated into a re-interpretation 
and subsequent release of a maiden inferred 
resource of 104 million tonnes at 0.7% Cu 
and 0.5 g/t Au1. The Fremantle Doctor deposit 
provides another valuable input into the 
company’s ‘life of province’ planning and will help 
inform expansion studies currently in progress.

At Khamsin, the four holes drilled in 2018 all 
returned broad intersections of zoned bornite 
and chalcopyrite mineralisation. A standout 
intersection of 402.6 m at 1.38% Cu and  
0.27 g/t Au in DD18KMS031 (from 735m)2 
extended the previously interpreted high grade 
domain to the south-west. The drilling results 
are currently being used to help model the area’s 
geology, which will improve understanding of  
the project and guide further drilling.

Musgrave province

The Musgrave province is a highly 
prospective region spanning Western 
Australia and South Australia.  
OZ Minerals has two projects in the 
area, the West Musgrave project with 
Cassini Resources which is currently 
in the pre-feasibility study stage, and 
the East Musgrave exploration joint 
venture with Woomera Exploration Ltd 
that targets magmatic copper–nickel 
sulphide systems. 

West Musgrave project
The West Musgrave project is located in  
Western Australia, near the South Australian 
border. It is Australia’s largest undeveloped 
copper–nickel project. 

West Musgrave contains three known deposits – 
Nebo, Babel and Succoth, and the One Tree Hill 
prospect. The further scoping study completed in 
2017 proposed developing the Nebo and Babel 
deposits as a low cost, long life, open pit mine. 
The most financial potential was seen in the  
10 Mtpa case, which generated an eight year 
mine life and an annual average net cash flow  
of $120–$150 million1. 

//
The Musgrave area is 
an exciting new mineral 
province with attractive 
near-mine and district 
opportunities.

A pre-feasibility study (PFS) on the project 
is almost complete. It focuses on improving 
metallurgical recoveries, lowering costs for non-
process infrastructure, and resource conversion. 
OZ Minerals is leading the study and our joint 
venture partner, Cassini Resources, is managing 
on-the-ground activities. The PFS is scheduled for 
completion in Quarter 2 2019. A parallel regional 
exploration program led by Cassini Resources is 
also underway and focuses on the One Tree Hill 
prospect and Succoth copper deposit. 

2018 highlights 

 /

In 2018, we progressed to 51% ownership  
by spending $22 million on the project.  
OZ Minerals has the option to progress to 70% 
ownership by spending a total of $36 million. 

 / Early results from the PFS metallurgical test work 
are encouraging and showed improvement in 
copper and nickel recovery and an increased 
grade of copper concentrate. 

 / The regional exploration program revealed a 
second significant intersection of copper and 
nickel mineralisation at the Yappsu prospect, 
just six kilometres east of Nebo and Babel.  
This demonstrates the province’s potential.

 / We completed the 2018 resource drilling 
program ahead of schedule which has  
enabled the 2019 infill drilling program to  
be brought forward.

 / We completed the exploration program at 

Succoth to test geological interpretation and 
inform 2019 exploration drilling.

 / Key leaders were appointed and our team has 

been given resources to deliver the PFS, resource 
assessment, community engagement and 
agreements, and approval programs.

Additional highlights from the PFS
 / A water modelling program of regional 
groundwater resources was completed. 

 / We completed the geotechnical drilling  
program around the current pit outline. 

 / We began the engineering study, which includes 
processing and non-processing infrastructure. 

 / Expressions of interest have been sought for 

power supply solutions. 

 / The West Musgrave camp was expanded to 

support increased on-ground activity.

The team has also been working on strengthening 
relationships with the local community and 
traditional owners. A number of community 
meetings were held during the year and we 
began a cultural heritage program to identify 
areas of cultural significance. The team is working 
alongside the traditional owners to develop a 
shared vision of what the project could look like. 

Our focus for 2019 is to: 
 / complete the PFS

 / further strengthen relationships with  

the local community

 / progress project approvals

 / develop a mining access agreement with  

the traditional owners

 / complete the inaugural ore reserve 

 /

implement new ways of working to pilot  
how OZ Minerals undertakes major projects. 

East Musgrave
The East Musgrave project with Woomera 
Exploration targets magmatic nickel–copper 
sulphide systems similar to those of the Nebo-
Babel deposits in West Musgrave. The Project  
is located in the Musgrave province, 500 km  
east of the West Musgrave project in South 
Australia’s far north. 

After drilling is complete, OZ Minerals has  
the option to earn up to 51% of the project  
by spending $2.5 million within 18 months.  
An additional spend of $5.0 million within  
two years will allow OZ Minerals to progress  
to 75% ownership.

2018 highlights 
 / We began negotiations for a Native Title  

Mining Agreement with Tjayuwara Unmuru  
Aboriginal Corporation, traditional owners  
of East Musgrave. 

 / We completed an electro-magnetic survey  

and defined six targets for drill testing.

 / We began drill testing of six targets to look 

for magmatic nickel–copper sulphide systems 
similar to those of the Nebo-Babel deposits

Brazil

In August 2018, OZ Minerals completed 
an off-market takeover of the Australian-
listed company Avanco Resources 
Limited (Avanco) for a net purchase 
consideration of $428.3 million. 
With an operating mine and a number of 
advanced projects in Brazil, this represented  
a strategic opportunity for OZ Minerals to  
diversify our portfolio and add to our organic 
growth pipeline. 

Brazil is a stable operating jurisdiction and 
supports mining. This acquisition has given  
us a major foothold in two world class mineral 
provinces: the Carajás Copper Region and the 
Gurupi Greenstone Belt. 

On completion of the takeover, a small  
dedicated team has been focused on integrating 
the Brazilian assets into OZ Minerals, optimising  
the asset portfolio, and introducing the required 
systems and processes to align with our  
operating philosophy. 

Avanco and OZ Minerals shared a strong cultural 
alignment and we retained Avanco’s in-country 
Brazilian management team and employees. They 
have a proven track record of project delivery and 
hold strong relationships with local stakeholders. 

Brazilian assets
The Brazilian assets have been part of the 
OZ Minerals portfolio for six months. In line 
with good practice, a review, verification and 
improvement process is underway, applying  
the OZ Minerals value lens to prioritise and  
phase project development.

The Carajás province is a premier mineral  
province located in northern Brazil. It hosts the 
world’s largest concentration of quality, large 
tonnage IOCG deposits. 

We hold an asset and two projects in the  
Carajás province:

 / Antas – an operating copper–gold mine 

 / Pedra Branca – an IOCG project currently  

in the definitive feasibility stage

 / Pantera – a high-grade copper–gold 

exploration project covering approximately  
100 square kilometres.

The Gurupi province is an underexplored and 
emerging geological region that hosts several 
large gold deposits. The province is located in 
the Brazilian state of Maranhão, between the 
cities of Belém and São Luis. It is close to existing 
infrastructure, including sealed roads, power, 
water and skilled labour. 

We hold one development project in the Gurupi 
province, CentroGold. This gold project is 
currently in the pre-feasibility study stage. 

Antas

Antas is a small, high grade, open-pit copper 
–gold mine located in the state of Pará, in 
northern Brazil. The mine produced 5,887 tonnes 
of copper and 4,791 ounces of gold in 20181.

Antas has been operating since July 2016 and 
successfully completed the ramp up to full 
production on schedule. The processing plant is 
operating above 800 ktpa and has been designed 
to support increased capacity. 

2018 highlights 
 / Management of the asset was transitioned  

to OZ Minerals effectively. 

 / We completed over 4,500 metres of resource 

delineation drilling.

 / Optimisation improvements resulted in greater 

efficiencies and cost savings.

 / We commenced a review of the open pit 

mineral resource and mine plan. 

 / 16 of 20 trainees from the company training 
program were employed at Antas, a record  
for the company. 

Our focus for 2019 is to: 
 / maintain high performance and pit  

operating efficiencies

 /

implement the optimisation opportunities 
identified in 2018

 / complete a review of the open pit mineral 

resource and mine plan 

 / continue mine life extension work with  

a near-mine exploration program 

 / continue to integrate OZ Minerals’  

governance structures

 / strengthen relationships with local community.

Pedra Branca

Pedra Branca is an IOCG project located in the 
southern part of the Carajás province, 100 km 
south of Paraupebas. 

The project comprises two adjacent high-grade 
copper–gold deposits: Pedra Branca East and 
Pedra Branca West. In 2017, a pre-feasibility study 
conducted by Avanco recommended a 1.2 Mtpa 
underground mine targeting Pedra Branca East 
and pre-production capex of ~US$158 million1. 
Annual production is estimated at 24 kt copper 
and 16 koz gold1.

A definitive feasibility study (DFS) is currently 
underway and focuses on further refining the 
mine plan and construction costs, and completing 
basic engineering. 

2018 highlights 
 / We progressed the DFS work.

 / Early site works began after we received  

key provisional licences.

 / Resource delineation drilling began. 

 / A water tank was installed to provide  

20 farming families on nearby land with  
access to fresh water. 

Our focus for 2019 is to: 
 / progress the DFS, including the mineral  

resource update, mining studies and basic  
plant engineering.

Pantera

Pantera is a high-grade copper–gold exploration 
project covering approximately 100 square 
kilometres in the Carajás province. It is located 
about 110 km west of Pedra Branca and is close 
to infrastructure. 

OZ Minerals has the option to acquire  
100% ownership of the project from Vale  
for US$20–$35 million (total investment)  
over a 7–10 year period. 

In 2018 an initial 5,000 m resource delineation 
drilling program yielded a maiden inferred  
mineral resource estimate of 20.8 Mt at  
1.7% copper and 0.2 g/t gold2. 

Our focus for 2019 is to continue resource 
delineation drilling and complete a conceptual 
mine design study.

CentroGold

CentroGold is one of the largest undeveloped 
gold projects in Brazil. It is located in the 
Brazilian state of Maranháo, between the cities 
of Belém and São Luis, and is close to existing 
infrastructure, power and water. The project 
comprises 1,370 square kilometres of tenements 
and lies within the Gurupi Greenstone Gold Belt. 

The project is currently in the pre-feasibility study 
(PFS) stage and hosts three deposits: Blanket, 
Contact and Chega Tudo. 

The larger CentroGold area has exceptional 
exploration potential. Interpretation of a vast 
database of historical information, including 
drilling and numerous studies, suggest that  
there is significant potential for new discoveries.

2018 highlights 
 / We continued resource delineation drilling 

into the Contact deposit.

 / We began the ’Hill of Value’ optimisation 

exercise to identify the optimal project value 
and scale.

 / Avanco Resources completed a CentroGold 
scoping study that demonstrated potential  
for a high-grade, low capex project.

Our focus for 2019 is to: 
 / continue the approvals process and engage  

local communities

Exploration and growth

OZ Minerals’ dynamic pipeline of  
growth projects progressed and 
expanded during 2018. 
Three new earn-in agreements were signed:  
East Musgrave with Woomera Exploration  
Limited; Lannavaara with Mineral Prospektering  
i Sverige AB; and Paraiso with Inversiones Mineras 
La Chalina S.A.C. The acquisition of Avanco 
Resources Limited provided OZ Minerals with the 
second largest exploration portfolio in Brazil and 
an active earn-in agreement with Vale S.A. on the 
Pantera project (see Brazil, p. 16 for details). 

OZ Minerals withdrew from the Alvito earn-in 
agreement in Portugal following drill testing of 
eight target areas. Drilling confirmed the presence 
of an IOCG system but no significant intersections 
were returned. 

The Mount Woods earn-in agreement with 
Minotaur Resources on exploration licences 
surrounding the Prominent Hill mining lease 
concluded by mutual agreement, following a 
second round of electromagnetic surveying and 
testing of geophysical and structural targets. No 
significant intersections of targeted iron-sulphide–
copper–gold mineralisation were returned during 
the program’s second year. The team is continuing 
to review previous work in the Prominent Hill area 
and investigate new exploration techniques. 

Ongoing partnerships with Amazon Web Services 
are modernising the way OZ Minerals manages 
and maintains exploration data. In 2018 data 
was migrated to platforms with expanded data 
storage, access and analytical capabilities. In 2019, 
the partnership will begin developing analytical 
algorithms and processes which will help us to 
interpret multidisciplinary data sets and streamline 
exploration and decision-making processes. 

OZ Minerals, in collaboration with Unearthed 
Solutions, announced the Explorer Challenge –  
a unique and innovative approach to advancing 
exploration on the tenements surrounding 
Prominent Hill. The crowd-sourcing challenge 
invites competitors to find new and innovative 
techniques and models that target base metal 
mineralisation in the prospective Gawler  
Craton. As part of the initiative, OZ Minerals  
will release its database amassed from over  
20 years of exploration to the public for analysis, 
data manipulation, and target generation.  
Data scientists and geoscientists alike are invited 
to compete for a one million dollar prize pool.  
The competition was announced in December 
2018 and will run from February to May 2019.

Exploration portfolio
Coompana with Mithril Resources consists 
of seven exploration licences in South Australia’s 
far western Coompana province. OZ Minerals 
is working with the Far West Coast Aboriginal 
Corporation on a Native Title Mining Agreement 
for exploration. In 2017, the South Australian 
Department of State Development in collaboration 
with PACE Copper conducted a significant 
number of airborne and ground geophysical 
surveys in the area. A scientific drill program was 
sponsored by Geological Survey of South Australia 
in conjunction with Geoscience Australia and the 
results have been released publicly for review. 

Punt Hill with Red Metal Ltd is targeting 
IOCG mineralisation in the area adjacent to 
Carrapateena. Previous work on Punt Hill 
uncovered many examples of IOCG mineralisation 
and one of the new prospects shows a number  
of geophysical similarities to Carrapateena 
deposits. The team initially focused on obtaining 
local level agreements with traditional owners and 
landowners. A 6,000 metre drilling program that 
focused on priority targets was completed with 
results expected in Quarter 1 20191.

Exploration Alliance with Red Metal Ltd  
was completed in early 2019. The Exploration 
Alliance with Red Metal allows OZ Minerals to 
jointly explore chosen projects from the Red  
Metal portfolio of base metal and gold/silver 
prospective projects. Preliminary plans have 
been made for 2019 and 2020 which include 
geophysical and/or drill coverage activity 
(depending on target maturity) in six areas in 
Queensland and Western Australia.

Eloise with Minotaur Exploration is targeting 
Eloise-style massive sulphides in the highly 
prospective eastern succession of the Mount 
Isa block, 60 km south-east of Cloncurry, 
Queensland.

Off the back of positive drilling results in 2017 at 
the Jericho prospect, we acquired a 51% interest 
in the Project and have the option to earn up to 
70% with an additional $5 million spend. 

A total of 38 drill holes have now been completed 
on the Jericho prospect and they continue to 
intersect mineralisation along the entirety of the 
Jericho trend. The mineralised structure remains 
open along strike and at depth. 

A number of regional targets with similar 
geophysical characteristics to Jericho were tested 
in the second half of 2018 and all intersected 
anomalous copper and gold. However, our focus 
remains on Jericho in the immediate forward plan. 
Internal modelling and evaluation of the project 
has commenced and an infill drilling program 
is currently being planned in order to build 
confidence in the upper 300 metres of the J1  
and J2 mineralised structures.

Paraiso with private Peruvian company, 
Inversiones Mineras La Chalina S.A.C., is  
exploring for IOCG deposits in the Arequipa 
district of southern coastal Peru. 

OZ Minerals can earn up to 75% of the project  
by spending US$10.0 million over five and half  
years and has the right to purchase a further  
25% equity. 

The initial work program is planned to  
include geological mapping, rock chip and soil 
sampling, ground geophysics and an airborne 
magnetic survey.

OZ Minerals has committed to spending  
US$0.5 million on exploration in the first  
12 months, after which it can elect to proceed 
with the project. If we elect to progress,  
we can earn 100% of the project by spending 
US$11.5 million over five years.

Lannavaara with Mineral Prospektering  
i Sverige is targeting IOCG mineralisation in  
the Norbotten district of northern Sweden. 

Multi-method geophysics surveys began 
in Quarter 4, including ground-based 
electromagnetic, gravity and magnetic data 
acquisition. These surveys confirmed the presence 
of anomalies identified in pre-competitive data 
and further refined the position of potential drill 
targets. A gridded, base-of-till drilling program 
was conducted during Quarter 4 to collect 
geochemical samples of the bedrock beneath 
periglacial and transported cover. A second phase 
of geochemical sampling and geophysics surveys 
will be conducted during the winter so as not 
to interfere with local reindeer herding and to 
minimise the overall environmental impact. 

Drill testing is expected to commence in the  
first half of the year.

Oaxaca with Acapulco Gold Corp is focused 
on base metal projects in Oaxaca, South Mexico 
and is targeting the Riqueza Marina, Zaachila 
and Zapotitlán sites. The sites have potential for 
volcanic-hosted massive sulphide deposits.

Field work at Riqueza Marina led to the discovery 
of more surface copper, zinc, gold, and silver 
mineralisation, approximately 1.2 km east of 
previously reported gossanous sub-crop. Ground 
magnetic and gravity surveys were subsequently 
completed at Riqueza Marina. These identified a 
coincident gravity and magnetic anomaly beneath 
alluvial cover and adjacent to outcropping 
gossanous rocks, and another gravity high 
over the area containing surface base metal 
mineralisation. The geophysics will help to inform 
a 2019 drill program.

Mapping and geochemical sampling 
undertaken at Zaachila outlined a copper-oxide 
mineralisation at the surface over a strike length 
of approximately two kilometres along a key 
geological contact. Gravity and ground magnetic 
surveys covering this zone commenced in  
Quarter 4.

We have secured community access agreements 
and environmental permits for Riqueza Marina 
and drill permitting documents were submitted  
in November.

Governance

OZ Minerals provides strong governance to enable lean business processes, clear 
accountability and room for innovation. This is fundamental to our business strategy.

OZ Minerals’ management structure
Our management structure, Governance and Risk 
Policy, and supporting standards provide clear 
guidelines and reporting structures to ensure our 
activities reinforce the corporate strategy and are 
conducted in a financially, environmentally and 
socially responsible way.

OZ Minerals’ Board is committed to adopting the 
recommended corporate governance practices 
set out in the ASX Corporate Governance Council 
Principles and Recommendations.

The Board is responsible for overseeing the 
management of the Company. The Board has 
adopted a Board Charter that sets out its roles 
and responsibilities, which includes setting the 
Company’s goals and objectives, reviewing and 
monitoring the Company’s material risks and 
its system of internal compliance and controls, 
setting an appropriate corporate governance 
framework, and determining broad policy issues 
for the Company. The Board also ensures that 
specific powers and responsibilities have been 
delegated to the Company’s Executive Committee 
and that the overall strategy is aimed at delivering 
value for shareholders.

The Board currently comprises six directors, 
one executive director and five non-executive 
directors. The executive director is Managing 
Director and Chief Executive Officer, Andrew 
Cole. The Board has a unitary structure. All non-
executive directors, including the Chairman, are 
independent. The proportion of women on the 
Board is 33 per cent1.

Three standing committees help the Board with 
the effective discharge of its responsibilities.

Audit Committee – assists the Board in the 
effective discharge of its responsibilities in relation 
to financial reporting and disclosure processes, 
internal financial controls, funding, financial risk 

management, including hedging and the internal 
and external audit functions, and oversight of the 
internal control and risk management system’s 
effectiveness.

People & Remuneration Committee – assists 
the Board in discharging its responsibilities relating 
to the remuneration of directors, executives 
and employees, succession planning, and the 
Diversity and Inclusion Policy’s establishment and 
monitoring.

Sustainability Committee – assists the  
Board in the effective discharge of its 
responsibilities in relation to safety, health, 
environment and community (SHE&C) issues  
for the OZ Minerals Group. This includes 
managing the risks relating to SHE&C issues 
by meeting the Company’s requirements for 
internal notification, investigation, reporting and 
continuous improvement, and overseeing the 
public reporting and disclosure processes insofar 
as they relate to SHE&C risks.

OZ Minerals’ management team
Management is responsible for implementing 
management systems across the business and 
monitoring the application and effectiveness 
of these systems through internal and external 
audits. Training and competency are part of  
the continuous improvement process and are 
detailed in the Performance Standards.

OZ Minerals has a devolved operating  
model ensuring its assets are autonomous  
and accountable, with the corporate centre 
focused on strategy, customers and owners, 
assurance and growth. With the acquisition  
of international assets and the focus on 
innovation, transformation and developing  
our people, a review of the devolved model  
in 2018 resulted in some changes to the  
construct of the Executive Committee.

ANNUAL AND SUSTAINABILITY REPORT 2018OZ Minerals is revising its business process 
standards so that they describe, in the simplest 
possible way, processes or the management 
activities that occur across the business in a 
repeatable manner. They are the activities that 
we undertake that are unique to OZ Minerals, 
and they will be used by OZ Minerals’ employees, 
contractors and assets. They define the inputs  
and outputs required, the processes people  
must follow and the delegations that they can 
work within.

All corporate and further-developed asset 
documents comply with the laws and regulations 
of the jurisdiction in which each asset operates.

Internal and external audits
OZ Minerals conducts regular audits to 
systematically and objectively verify that  
it conforms to performance management  
standards and legal requirements, and in order  
to recommend ways to improve safety, health  
and wellbeing along with environmental  
and social performance. Further audits are  
undertaken commensurate with the risk profile.

Governance Framework

The governance framework at  
OZ Minerals has been designed  
to enable lean business processes  
that drive clear accountabilities and 
create room for innovation.
We focus on what matters, and set processes 
that create value, embrace the global devolved 
business model and provide clarity for new assets, 
partners, suppliers and employees coming into  
OZ Minerals.

Our values and behaviours drive transparency 
and fair dealing, and propagate a culture of 
performance and devolved accountability – this 
allows us to deliver on our Company strategy.  
OZ Minerals’ Code of Conduct applies standards 
for appropriate ethical and professional behaviour 
and guides OZ Minerals’ employees, directors, 
contractors and partners.

The Code of Conduct provides clear guidelines 
as to our expectations in regards to a number 
of specific issues, such as conflict of interest, 
gifts, entertainment and gratuities, anti-bribery, 
fraud and corruption, equal opportunity and 
whistleblowing.

OZ Minerals’ nine Company policies work 
synergistically to provide a clear representation 
of our intent while providing a platform for 
multiple assets to work together under a global 
devolved model. Policy documents, our Securities 
Trading Procedure and our Continuous Disclosure 
Procedure are publicly available and are used 
to clearly articulate what we strive for to all 
stakeholders, partners and communities.

Underpinning the policies are performance 
standards that are grouped into four key areas. 
These are safety, environment, health and 
wellbeing, and social. They define the minimum 
required performance to manage sustainability 
opportunities and threats.

These standards will be used to audit asset 
performance and set the standards for any new 
assets to achieve. They are provided to contractors 
and partners to outline what we expect when 
they work at an OZ Minerals asset. These 
documents are structured so that each asset, 
contractor or partner can use or develop their 
own business standards and processes to meet 
our standards, in keeping with our lean,  
global devolved business model.

overseas activities. OZ Minerals’ Antas operations are also subject to environmental regulations under 
legislation in Brazil.

OZ Minerals regularly monitors its compliance with licenses and permits in various ways, including 
through its own environmental audits as well as those conducted by regulatory authorities and other 
third parties. OZ Minerals uses a documented process to classify and report any exceedance of a 
licence or permit condition as well as any incident reportable to the relevant authorities. All instances 
of reportable environmental non-compliance and significant incidents are reviewed by the Executive 
Committee and the Sustainability Committee of the OZ Minerals Board of Directors as a part of this 
process. A formal report is also prepared to identify the factors that contributed to the incident or  
non-compliance and the actions taken to prevent any reoccurrence.

During the year, OZ Minerals submitted the energy and emissions report to the Clean Energy Regulator 
in accordance with the National Greenhouse and Energy Report Act 2007 (NGER Act). A limited 
assurance engagement of OZ Minerals’ energy and emissions report was conducted by an independent 
auditor over the emissions, energy production and energy consumption report prepared in accordance 
with the NGER Act.

Insurance and indemnity
During the financial year, OZ Minerals Limited paid premiums with respect to a contract insuring its 
directors, officers and related bodies corporate against certain liabilities incurred while acting in that 
capacity. The insurance contract prohibits disclosure of the liability’s nature and the amount of the 
insurance premium.

The Company’s constitution also allows OZ Minerals to provide an indemnity, to the extent permitted 
by law, to officers of the Company or its related bodies corporate in relation to liability incurred by an 
officer when acting in that capacity on behalf of the Company or a related body corporate.

The Consolidated Entity has granted indemnities under deeds of indemnity with current and former 
Executive and Non-executive Directors, former officers, the former General Counsel-Special Projects,  
the former Group Treasurer and each employee who was a director or officer of a controlled entity of 
the Consolidated Entity, or an associate of the Consolidated Entity, to conform with Rule 10.2 of the  
OZ Minerals Limited Constitution. 

Each deed of indemnity indemnifies the relevant director, officer or employee to the fullest extent 
permitted by law for liabilities incurred while acting as an officer of OZ Minerals, its related bodies 
corporate and any associated entity, where such an office is or was held at the request of the Company. 
The Consolidated Entity has a policy that it will, as a general rule, support and hold harmless an 
employee who, while acting in good faith, incurs personal liability to others as a result of working  
for the Consolidated Entity. 

No indemnity has been granted to an auditor of the Consolidated Entity in their capacity as auditor  
of the Consolidated Entity.

Proceedings on behalf of the Consolidated Entity
At the date of this report there are no leave applications or proceedings brought in respect of or  
on behalf of the Consolidated Entity under section 237 of the Corporations Act 2001.

Audit and non-audit services
KPMG continues in office in accordance with the Corporations Act 2001. A copy of the lead auditor’s 
independence declaration is set out on page 98 as required under section 307C of the Corporations Act 
2001 and this forms part of the Directors’ Report. 

OZ Minerals Limited, with the approval of the Audit Committee, may decide to employ the external 
auditor on assignments additional to their statutory audit duties where the auditor’s expertise and 
experience with the Consolidated Entity are important, and where these services do not impair the 
external auditor’s independence.

The Audit Committee has, following the passing of a resolution by the Committee, provided the  
Board with advice in relation to KPMG providing non-audit services.

In accordance with the advice received from the Audit Committee, the Board is satisfied that the 
provision of the non-audit services is compatible with the general standard of independence for 
auditors imposed by the Corporations Act 2001. The directors are satisfied that the non-audit 
services provided by the auditor did not compromise the auditor independence requirements of the 
Corporations Act 2001 because:

 / all non-audit services were reviewed by the Audit Committee to ensure they did not impact the 

integrity and objectivity of the external auditor

 / none of the services undermined the general principles relating to auditor independence as set  

out in APES 110 Code of Ethics for Professional Accountants. These include reviewing or auditing  
the auditor’s own work, acting in a management or a decision-making capacity for OZ Minerals 
Limited or its controlled entities, acting as advocate for the Company or jointly sharing economic  
risk and rewards.

Matters subsequent to the end of the financial year
Since the end of the financial year, the Board of Directors has resolved to pay a fully-franked dividend 
of 15 cents per share on 26 March 2019. The record date for entitlement to this dividend is 12 March 
2019. The financial impact of the dividend amounting to $48.4 million has not been recognised in the 
Consolidated Financial Statements for the year ended 31 December 2018 and will be recognised in 
subsequent Consolidated Financial Statements.

There have been no other events subsequent to the reporting date which have significantly affected  
or may significantly affect OZ Minerals’ operations, state of affairs or results in future years.

Rounding of amounts
The Company is of a kind referred to in ASIC Corporations Instrument 2016/191 (Rounding in financial/
directors’ reports). Amounts in the financial statements and Directors’ Report have been rounded in 
accordance with the instrument to the nearest million dollars to one decimal place, or in certain cases, 
to the nearest dollar. All amounts are in Australian dollars unless otherwise stated.

OZ Minerals’ net profit after tax (NPAT) for the year was $222.4 million, which was $8.7 million (or 4%) 
lower compared to 2017. The underlying NPAT1 for the year was $228.3 million after adjusting for the 
acquisition costs associated with the Avanco transaction of $5.9 million. Prominent Hill continued its 
consistent production performance and benefited from the high copper prices in the first half of 2018. 
During the year, the consolidated entity increased exploration and evaluation expenditure to progress 
its growth pipeline as well as evaluating expansion options at Prominent Hill and Carrapateena which 
also contributed to the result for the year. Earnings before interest, tax, depreciation and amortisation 
(EBITDA) margins remain robust at 48 per cent. OZ Minerals’ cash balance of $505.1 million, decreased 
by $224.3 million compared to 2017 after capital investment at Carrapateena, the acquisition of 
Avanco Resources Limited (Avanco), expenditure on exploration activities, tax payments, and dividend 
payments to shareholders which was partly offset by increased operating cash flows.

Revenue
2018 revenue was $93.9 million higher when compared to 2017 with higher commodity prices, 
consistent production from Prominent Hill and revenue from Antas. The amount of contained copper 
sold (114,722 tonnes) was two per cent higher than in 2017 while gold sales of 131,929 ounces were 
comparable to 2017 sales. 

In 2018, the average $A copper price was eight per cent higher than in 2017, while the average  
$A gold price was three per cent higher. Sales from Prominent Hill and Antas benefited from strong 
copper prices during the year, particularly during the first half of the year when the copper price was 
five per cent higher than in the second half. 

Realisation costs
Treatment charges and refining costs (TCRC) were $13.0 million lower as a result of improved trading 
terms and lower refining charges in the market.

Royalty expenses increased by $3.4 million because of higher sales in this period compared to the 
previous period.

Production costs
Production costs in 2018 were $57.2 million higher than the previous year, with the inclusion of Antas 
in the second half of the year, an increased proportion of underground ore and higher power costs at 
Prominent Hill. 

Mining costs including inventory movement and net realisable value (NRV) adjustment were  
$30.5 million higher than prior year. Mining costs incurred during the year were $243.4 million lower  
in 2018 as open pit mining ceased in Quarter 1. Open pit ore stockpiled in previous periods began to  
be processed from Quarter 2 2018 following the closure of the Prominent Hill Open Pit. During the  
year $83.7 million was recognised as an inventory cost in the Income Statement which also included  
$25 million write up for NRV adjustment. During the year ending 31 December 2017 (comparative 
period) while ore inventory was stockpiled, mining costs of $190.2 were capitalised in to inventory. 

Processing costs increased by $19.2 million due to the inclusion of Antas in the second half of 2018  
and higher power prices at Prominent Hill, as previously anticipated.

Exploration and development expenditure
Exploration and evaluation expenditure of $67.2 million was incurred during the year to progress the 
West Musgrave project, Carrapateena expansion study, Gurupi province, Carajas province and other 
exploration earn-in arrangements in the growth pipeline: 

 / West Musgrave $23.4 million

 / Carrapateena expansion $11.4 million

 / Brazil exploration $13.0 million

 / other exploration and development expenditure $19.4 million.

Other expenditure
Corporate general and administration costs of $29.0 million are largely related to corporate activities. 
These were $5.6 million higher than the comparative period as a result of the increased focus on 
exploration and development.

The income tax expense of $90.5 million was $7.8 million lower than the previous year as a result of  
the lower profit and the benefit of tax losses recognised during the year.

Acquisition costs associated with the Avanco transaction of $5.9 million net of tax relating to due 
diligence, legal, transaction and consulting fees were recognised as a non-underlying expense during 
the year.

ANNUAL AND SUSTAINABILITY REPORT 2018 
Operating cash flows
Operating cash flows of $449.6 million for the year were $106.7 million higher than in 2017. This was 
principally due to the benefit of higher commodity prices in the first half of the year and the drawdown 
of stockpiled material at Prominent Hill, partially offset by tax payments and further investment in 
exploration activities. Customer receipts were $203.8 million higher as a result of the sales and copper 
price realised during the year. Income tax payments of $148.7 million were in relation to 2018 and 
finalisation of the 2017 tax liability. 

Investing cash flows
Net investing cash flows of $609.7 million represent payments for the Avanco acquisition; property, 
plant, equipment and mine development at Prominent Hill and Antas; development costs at 
Carrapateena; exploration costs of the West Musgrave project; and receipts from the sale of surplus 
mining equipment.

The payments incurred related to:

 / Capitalised Carrapateena project costs $335.0 million

 / Prominent Hill mine development costs $58.7 million

 / Sustaining capital expenditure $12.5 million

 / Other capital expenditure $20.2 million

 / Avanco shares acquisition $222.4 million, partially offset by Avanco’s cash balance of $39.1 million 

acquired as at 30 June 2018.

Financing activities
Cash outflows relating to financing activities comprised $67.6 million in dividend payments to 
shareholders. 

Since the end of the financial year, the Board of Directors has resolved to pay a final dividend 
amounting to $48.4 million in respect of the 2018 financial year. This final dividend will be fully  
franked for Australian tax purposes.

Balance sheet
Total equity increased by $398.9 million during the year to $2,915.2 million. This was mainly due to 
equity issued for the acquisition of Avanco ($245.0 million) and the current year profit ($222.4 million), 
which was partially offset by $67.6 million in dividends and a $17.8 million (net of tax) decrease in the 
value of gold derivative contracts.

Net assets 2018

The Company ended the year with a cash balance of $505.1 million and undrawn debt facilities of 
$100.0 million, with an uncommitted facility for $300.0 million, providing the liquidity and flexibility  
for the Company to execute its growth strategy.

Inventories at 31 December 2018 were $678.4 million, of which non-current ore stockpiles decreased 
by $82.8 million as the Prominent Hill open pit stockpile processing commenced. A net realisable 
value write-back of $25.0 million was applied to the low grade gold ore stockpiles (the estimated net 
realisable value is based on revenue expected to be derived from metal contained in the ore stockpiles, 
based on the processing operational plan, and after adjustment for incremental costs). As open pit 
ore stockpiles are consumed, the costs of mining open pit ore and the related capitalised depreciation 
(collectively comprising open pit ore inventory) will be amortised progressively and recognised in the 
income statement.

Trade receivables at the end of the year of $70.9 million were $51.0 million lower than the previous 
year due to the timing of shipments. 

Property plant and equipment (PP&E) increased during the year mainly due to the acquisition of  
Avanco PP&E, including mineral rights of $615.5 million, capitalised underground development costs  
of $58.7 million; development capital expenditure at Carrapateena of $335.0 million; and sustaining 
and other capital expenditure of $40.9 million partially offset by depreciation of PP&E assets.

Studies on the Concentrate Treatment Plant (CTP) have concluded with a deep body of knowledge 
acquired and positive technical outcomes that provide optionality in the future. However, the Company 
has decided not to proceed with the CTP at this time. The capitalised costs relating to the CTP are 
classified within Other assets.

Risks
OZ Minerals’ operating results, financial results and performance are subject to a wide range of risks 
and uncertainties (both opportunities and threats) that can be financial, political, operational and 
environmental. The Consolidated Entity manages and mitigates these risks, where appropriate,  
to minimise adverse impacts from threats and maximise beneficial outcomes from opportunities.  
OZ Minerals’ simplified corporate governance structure and direct communication channels ensure 
timely responses to emerging risks. Our risk management framework emphasises risk aware decision-
making to achieve enhanced business outcomes.

The Board has oversight responsibility and determines the overall risk appetite for the Consolidated 
Entity. OZ Minerals operates a risk management system with multiple lines of defence. Line managers, 
operational staff and corporate functions establish standards for managing risk and the Board and its 
committees review risk management processes and material risk profiles as a part of their oversight 
role. The Company has identified the risks and mitigating factors that have the potential to affect 
future operating and financial performance (provided in the table below). Developing preventative 
and mitigating controls for threats is intended to minimise the adverse impact on the Company’s 
performance, but the Company’s future operations and financial performance may be significantly 
impacted should any of these elements fail or be disrupted.

Risks and mitigating factors that could affect OZ Minerals’ future operating and financial performance

Context 

Strategic risks

One operating asset 
Operating only one material 
operating asset exposes 
the Consolidated Entity to 
concentration risks. 

Climate change

Risk 

Mitigation/actions

The Prominent Hill mine generates most of the 
Company’s income and cash flow.

Climate change can cause disruption to mine 
production, logistics and water supply as a result of 
extreme weather events.
As regulatory agencies respond to climate change 
over the medium term, costs of inputs may rise and 
restrictions may be placed on how certain resources 
are provided, transported and used. This may adversely 
impact our assets.
Climate change combined with regulatory changes 
also has the potential to be a catalyst for growth 
in industries that require copper and could result in 
upward pressure on copper prices. 

Prominent Hill now operates an integrated underground mine with 
multiple areas. Following the completion of the open pit, the de-risked 
ore stockpiles increase certainty to the operations.
The Company has an active program which focuses on using trigger 
action response plans to maintain the ongoing stability of the open 
pit walls. The OZ Minerals maintenance and engineering team have 
developed robust procedures and practices to ensure they are  
operating the processing plant with minimal disruption and at high 
throughput levels. 
Progress the development of an additional significant operating project 
at Carrapateena.
Prominent Hill concentrate is transported to Australian destinations 
using road and rail and it is shipped to overseas destinations from 
the port of Adelaide. Spillage risks (and environmental impact) are 
mitigated by using customised containers with lids and rotainers to  
load concentrate onto ships. 
Addition of the Antas operation in Brazil, which is an operating open 
pit mine, and ongoing optimisation to increase contribution through a 
review of the Antas open pit Mineral Resource and mine plan.

OZ Minerals is committed to reducing the energy and water intensity  
of our operations, developing innovative practices in relation to 
chemical processing, and being more efficient in our transportation  
and processing activities.
The Company’s power strategy is focussed on opportunities  
for renewable energy, energy security and reliability for all of  
our operations.
Initiatives are underway across operations to reduce our environmental 
footprint including energy intensity, water use, waste management, and 
transport and logistics.
OZ Minerals is currently preparing a roadmap for reporting of integrated 
climate change risks and climate-related financial disclosures in line 
with the Taskforce on Climate-related Financial Disclosure (TCFD) 
framework.
The TCFD framework will also provide a process to gain a better 
understanding of physical and financial climate-related threats and 
opportunities which can then be further integrated into our company 
standards and policies.

Context 

Risk 

Mitigation/actions

OZ Minerals competes with other power users for  
a competitively-priced uninterrupted power supply 
within the prevailing environment of volatile electricity 
prices and power outages.

The existence of a large resource at the Prominent  
Hill operation, Carrapateena, Khamsin, Fremantle 
Doctor, West Musgrave (JV), Carajas, Gurupil, other 
exploration joint ventures and the prospectivity of the 
Gawler Craton.
In a climate of prospective commodity prices and 
expected long-term shortages in copper supplies,  
OZ Minerals competes with other entities to 
acquire and develop projects that generate superior 
shareholder value. 

Mine development projects are inherently  
exposed to risks of scope definition, cost estimation 
accuracy and other external factors which present  
threats and opportunities to a project’s cost,  
efficiency and profitability. These are not all within  
the Company’s control.

The production and capital costs incurred by 
OZ Minerals are subject to a variety of factors, 
including and not limited to: 
 / fluctuations in input costs determined by global 

markets (e.g. electricity, fuel and other key 
consumables)

 / changes in economic conditions that impact on  
the margins required by contracting partners
 / changes in mining assumptions, such as ore  

grades and pit designs. 

The operating results of OZ Minerals depend on  
the performance of contractors.

The collapse of a TSF has the potential to impact 
the safety of employees working in the area and 
community members in the vicinity of the area, 
company growth, disruption to the mine operation, 
severe damage to the environment and long term 
company reputational damage. It would likely result in 
damaged relationships with key stakeholders.  

The concurrent mining of multiple underground  
areas will lead to increased underground mining 
activities. The Antas mine open pit depth will increase 
as mining progresses. 
Progressive addition of tailings into the tailings  
storage facility.

Continuity of power supply
The Prominent Hill mine and 
Carrapateena project are both 
located in South Australia, with 
common sources of generation 
through the connected grid.

Growth strategy 
A key element of the Company’s 
growth strategy is growth through 
acquisition or development of 
value accretive copper assets. 

Operational risks

Project execution
Successful execution of OZ 
Minerals’ growth strategy depends 
on its ability to deliver projects on 
time and within budget and scope. 

Contract management
Many aspects of the Prominent 
Hill operations, Carrapateena 
project, Antas operations, and 
the Company’s exploration 
and development activities are 
conducted by contractors.

Tailings Storage Facility (TSF) 
management

Geotechnical failure
The open pit and underground 
mining operations including 
tailings storage facilities remain 
subject to geotechnical uncertainty 
and adverse weather conditions. 
These could manifest as pit wall 
failures or rock falls, mine collapse, 
cave-ins or other failures to 
mine infrastructure and reduced 
productivity.

The Company has developed a power strategy for the Gawler Craton  
to align with its business strategy. 
Prominent Hill and Carrapateena power supply contracts ensure power 
requirements for its operations in South Australia are met.
The Carrapateena and Prominent Hill power infrastructure agreements 
were executed in 2018 and construction is underway.

OZ Minerals has a clear pipeline of projects and gated plans which 
ensure a disciplined approach to leverage the large resource base.
OZ Minerals evaluates each opportunity with due care and relies  
on expert opinion, both internal and external where necessary, to 
ensure that any potential transaction will be value accretive to the 
Company’s shareholders.
OZ Minerals maintains a segregated approach to the identification and 
review of potential transactions and projects to ensure appropriate 
governance is applied over the assessment of financial risk and returns.
New capital management framework established.

OZ Minerals ensures its projects go through a process of internal  
and external independent review to verify the engineering, technical 
and financial scope definitions and other assumptions. 
The Company manages project costs by sound procurement  
practices and governance.

OZ Minerals engages with reputable contractors who have the  
technical ability, proven track record and financial capability to  
execute its projects. 
Competitive procurement processes and embedded performance 
structures in contracts ensure that the Consolidated Entity mitigates 
risks of non-performance by contractors, while deriving the highest 
value for shareholders.

OZ Minerals is committed to proactively managing TSFs across its 
operations through design and construction specifications, continuous 
maintenance, governance, inspection and monitoring programs. 
The ongoing management controls include management reviews, 
annual independent reviews, compliance with regulatory and licence 
requirements and the Australian National Committee of Large Dams 
(ANCOLD) guidelines and the TSF Operational Manual, geotechnical 
reviews and monitoring, detailed monitoring plans for the periods of 
closure and post closure until completion of rehabilitation, periodic 
stability analysis and comprehensive dam design reviews.  

OZ Minerals operates systems that prevent, monitor and respond to 
changes in geotechnical structures in the open pit, underground, and 
tailings storage facility to ensure the safety of personnel working 
in the affected areas. Activities are undertaken to reduce the risk of 
geotechnical failure to as low as reasonably possible.

recovery levels or the commercial viability of deposits 
can be provided. The Company reviews and publishes 
its reserves and resources annually. 

Customer management 
OZ Minerals markets high 
grade copper concentrate to 
overseas and local customers. 
Any disruption to the logistics 
chain from production through to 
delivery to the customer can result 
in significant financial impact.

Market risks

Commodity prices  
and exchange rates

Concentrate marketability depends on global mine 
supply, smelter demand, concentrate grades and 
impurities in the product. OZ Minerals’ concentrate has 
a high copper grade, containing gold and silver as well 
as some impurities such as fluorine and uranium. 
Regulators in various jurisdictions may change limits 
or their approach to impurity assessment guidelines 
in concentrate. This can impede the importation of the 
concentrate into those jurisdictions. These changes 
may result in additional requirements related to the 
ore, tailings or concentrates, or result in challenges 
with selling, transporting or importing OZ Minerals’ 
concentrates in various jurisdictions.

OZ Minerals does not control copper, gold, silver or other 
base metal prices in the global commodities market or 
the Brazilian REAL/Australian dollar exchange rate. 

The Mineral Resource and Ore Reserve estimates and mine plans  
have been carefully prepared by the Company in compliance with  
the Joint Ore Reserves Committee (JORC) guidelines and in some 
instances are verified by independent mining experts or experienced 
mining operators. 
The estimation of the Company’s reserves and resources involves 
analysis of drilling results, associated geological and geotechnical 
interpretations, operating cost and business assumptions, and a 
reliance on commodity price and exchange rate assumptions. 
The Company’s production plan is based on the published reserves  
and resources.

OZ Minerals has developed customised solutions in partnership with 
customers. These match smelter demand and production from the  
OZ Minerals mines to concentrate grade and timing, along with a range 
of controls to manage the fluorine and uranium impurities. 
OZ Minerals has multiple marketing options including, but not limited 
to, ore blending, concentrates blending and additional flotation 
treatment in the processing plant. 
OZ Minerals maintains a diverse customer portfolio to mitigate against 
the risk of regulatory changes to importation requirements.

OZ Minerals manages its exposure to copper price on invoiced sales by 
entering into derivative contracts that settle at the same time as the 
contractual quotation period for the sale.
OZ Minerals has entered into gold derivative contracts to fix gold price  
on 62.6 per cent of the gold expected to be sold to 2021.
OZ Minerals’ predominant functional currency is the Australian dollar  
and US dollars are only held to meet US dollar commitments. 
OZ Minerals does not take active steps to hedge currency risk.
OZ Minerals operates mines with a low cost of production relative to 
global copper producers. This ensures resilience to low commodity prices 
and an ability to maximise margins during high commodity prices.

Safety, health, environment, and community (SHEC)

Operational safety failures 
resulting in injury or fatality

OZ Minerals undertakes operations in areas which 
may pose a safety risk including, but not limited to, 
handling explosives; underground operations subject 
to rock fall; confined spaces; areas where heavy and 
light vehicles interact; manual handling; and operating 
at height. 
A fly-in fly-out operation also introduces risk that is 
inherent in air travel, as contractors and employees are 
regularly required to commute by aircraft. 

OZ Minerals is committed to the safety of its people and all work 
processes have a high safety focus.
OZ Minerals operates in partnership with its contractors and is actively 
building a shared safety culture between employees and the contractors 
who work at our sites. 
Active engagement at all levels of operations and with senior leadership 
teams, combined with activities focused on identifying and eliminating 
drivers of safety incidents, has delivered significant successes and 
resulted in a sustained reduction in the severity of injuries. 

Mine rehabilitation
The Company operates under 
a range of environmental 
regulations and guidelines.

Environmental regulations and occupational health 
and safety guidelines for certain products and by-
products produced or to be produced are generally 
becoming more onerous.

The Company is required to close its operations and rehabilitate 
the land affected by the operation at the conclusion of mining and 
processing activities. 
Estimates of these costs are reflected in accordance with AASB 137 
Provisions, Contingent Liabilities and Contingent Assets as provisions 
in the financial statements. Management seeks external assistance and 
review, where appropriate, to estimate these costs.
However, actual closure costs may be higher or lower than estimated 
as these are costs to be incurred following the closure of mining 
operations over a long time period.

Mitigation/actions

Managing and Protecting  
the Environment
OZ Minerals is committed to 
managing environmental threats 
and impacts associated with 
specific activities or tasks and 
to identify opportunities that 
have the potential to drive value 
creation for both OZ Minerals  
and the communities in which  
we operate.

Maintenance of community 
relations and good title

Non-compliance with environmental regulation has 
the potential to impact company growth, damage 
reputation and could result in damaged relationships 
with key stakeholders

The Company works closely with local communities 
across its global operations and projects, particularly 
the Indigenous communities in Australia.
Agreements with the Commonwealth of Australia 
govern the terms of access to areas located within the 
‘green zone’ of the Woomera Prohibited Area, where 
the Prominent Hill mine is located.
The Company adheres to local mining rules and 
regulations as a minimum, with its own practices  
often exceeding these requirements.

The OZ Minerals Risk Process Standard outlines the process of risk 
identification, assessment, management and reporting across all 
operations, including the requirement to take a risk-based approach 
to environmental management. Environmental risks for our operations 
are addressed by adhering to the conditions set out within the 
Performance Standards and legislative and regulatory requirements 
of the jurisdictions in which they operate. The Performance Standard 
conditions set out to address the following areas, surface water, ground 
water, flora and fauna, radiation, air emissions, land and biodiversity, 
roads, traffic and other infrastructure, and Indigenous and non-
Indigenous cultural heritage. Each operation has monitoring programs 
to ensure it meets the legislative, regulatory and other environmental 
requirements. The performance of each OZ Minerals operation is 
independently reviewed and reported against according to the 
conditions of relevant jurisdiction each year.

Access and compensation agreements are in place with communities 
affected by exploration and operational mining activities. These are 
reviewed and updated from time to time as required.
The Company has controls in place to ensure compliance with the deed 
covering the Woomera Prohibited area and local level agreements. 
It relies on good relations with the Australian Defence Department 
regarding defence operations in the Woomera region and any potential 
impact these may have on our mining operations.
The Company also relies on the maintenance of good title over the 
authorisations, permits and licences which allow it to operate. Loss 
of good title or access due to challenges instituted by issuers of 
authorisations, permits or licences, such as government authorities or 
land owners, may result in operational disruptions, adversely impact 
project development cost or schedule or restrict access to land for 
exploration and growth. 
Legal processes are being followed to facilitate the lifting of a legal 
injunction across the CentroGold project in Brazil, although there 
is no certainty as to the timing of remedies noting the number of 
stakeholders involved. The Company retains good relations with the 
local community.

Business strategies, prospects and likely developments 
This report sets out on pages 6–19, our business strategies and prospects for future financial years; 
likely developments in OZ Minerals’ operations; and the expected results of our operations in future 
financial years. We provide this information to help shareholders make an informed assessment about 
the business strategies and prospects for the Consolidated Entity’s future financial years. We have not 
included details that could give rise to a likely material detriment to OZ Minerals, such as information 
that is commercially sensitive, confidential or could give a third party a commercial advantage.

ANNUAL AND SUSTAINABILITY REPORT 2018Letter from the Chairman of the  
People & Remuneration Committee

Developments for remuneration  
for 2019 and beyond
As communicated in last year’s remuneration 
report, during 2018 the Company concluded a 
review of its executive remuneration framework 
to make sure it remained fit-for-purpose as  
OZ Minerals continues to grow.

The review concluded that the current 
framework continues to serve the Company 
well but identified opportunities to create a 
greater alignment between executives and 
shareholders over the longer term whilst ensuring 
remuneration remained market competitive, 
easy to understand and able to be clearly 
communicated to executives and shareholders.  
In summary, the key changes to the remuneration 
framework for 2019 include: 

 /

introducing an equity component to the STI 
with 30% of an executive’s STI being paid 
in equity subject to a two year holding lock. 
Maximum STI opportunities will be increased 
to 100% of TFR for KMP and 150% for the 
CEO to bring overall remuneration in line with 
market. The process for setting KPIs and 
assessing performance against them will remain 
unchanged and the outcomes will continue to 
be reported to shareholders annually. 

 / replacing the absolute share price performance 
measure for the LTI plan with a measure of 
All-In Sustaining Costs (AISC). We believe that 
keeping AISC in the bottom half of the cost 
curve over the long term is a key strategic driver 
of long-term performance. Executives will be 
eligible for a full payout of this component 
of LTI if company wide AISC over the vesting 
period is in the bottom quartile. 30% of 
LTI will be eligible to vest according to AISC 
performance with 70% continuing to be tested 
by RTSR (relative total shareholder return), in 
each case over a three year vesting period, 
which will remain unchanged.

 /

introducing a holding lock on equity which 
vests under future LTI plans, which will require 
executives to hold any vested LTI for a period 
of two years beyond the initial three year 
performance period.

 / broadening the scope of our malus and 

clawback provisions to include circumstances 
that bring the company into disrepute, or any 
catastrophic environmental or safety incident.

Dear shareholders,

On behalf of the Board of Directors, I am  
pleased to provide you with the 2018 
Remuneration Report for OZ Minerals.

2018 was a year of strong performance for 
the Company. We reached or exceeded our 
production guidance at Prominent Hill and 
met cost guidance at Prominent Hill, materially 
advanced the development of Carrapateena, 
pursued our growth strategy through the 
acquisition of Avanco (a company with an 
operating asset and a number of advanced 
exploration projects in Brazil) and continued to 
develop our exploration pipeline with new sites in 
Sweden and Peru. Shareholders benefited from 
a strong NPAT of $222.4 million and dividends of 
23 cents per share. 

The success of the Company during the year 
was a direct result of the talent, hard work and 
dedication of the Company’s employees and 
stakeholders. More detail on the Company’s 
performance is contained in the Director’s Report.

Remuneration outcomes in 2018
As in previous years, we continued to ensure 
that remuneration outcomes reflect the 
performance of the Company and were aligned 
to shareholders’ expectations. 

Key outcomes for 2018

 / Executive salaries were increased as detailed  

in last year’s report.

 / The strong performance of the Company 
against the KPIs set by the Board for the  
2018 year supported short term incentive 
awards to KMP of 83.3% on average of 
their maximum annual short term incentive 
opportunity. Details of the KPI outcomes  
can be found in section 3.2 of the 
Remuneration Report.

 / The Board awarded 83.5% of the maximum 
annual short term incentive opportunity to  
the Managing Director and Chief Executive 
Officer, Andrew Cole reflecting the strong 
performance of the Company and his  
leadership during 2018.

 / Vesting of performance rights to Andrew Cole

 / 154,344 performance rights for the 2015  

LTI plan, vested in June 2018 at 100%

 / 177,756 performance rights for the 2016  

LTI plan, vested in December 2018 at 88.34%

As foreshadowed in our report last year, the  
Board decided to increase the fees paid to  
Non-Executive Directors in September by an 
average of 5% noting that directors fees had not 
been increased in six in both scale and complexity. 
Details of directors fees can be found in section 
six of this report.

 /

introducing a requirement for executives and 
Non-executive Directors to acquire shares in the 
company equal to 100% of base fee for Non- 
executive Directors (over five years), 100% of 
fixed remuneration for the CEO and 50% for 
KMPs and other senior executives.  

Further details of the changes being implemented 
can be found in section nine of the Remuneration 
Report.

We believe these changes will put equity into 
the hands of executives earlier and require them 
to hold it for the long term, increasing the sense 
of ownership of the Company amongst our 
executives and encouraging decision making 
aligned to creating longer term shareholder value. 

These changes were made following extensive 
consultation with major shareholders and proxy 
advisors, and we are pleased that they were 
strongly supported.

During the year, we also conducted a 
comprehensive market benchmarking of executive 
remuneration, mindful of the need to continue to 
retain our key employees in a competitive market 
as the Company grows. The benchmarking 
demonstrated that whilst our fixed remuneration 
was, in most cases, in line with our preferred 
positioning, total remuneration was below our 
preferred positioning of toward 75th percentile for 
outperformance outcomes. We chose to address 
this by holding most executive fixed remuneration 
at around 2018 levels and increasing executive  
STI opportunities as outlined above. 

4 4

In the case of KMP, benchmarking supported 
modest increases to fixed remuneration for: 

 / Andrew Cole from $800,000 to $850,000 per 
annum recognising the increased scale and 
complexity of the company 

 / Warrick Ranson from $525,000 to $565,000 

reflecting market movements; and

 / Mark Irwin from $525,000 to $545,000 
reflecting his increased accountabilities.

We also reviewed the RTSR comparator group 
for the 2019 LTI award. Avanco, Nevsun and 
Turquoise Hill will be removed and Metals X 
Limited and Central Asia Metals Plc will be added, 
bringing the total number of companies in the 
comparator group to 14. 

The Board is determined to continue our focus 
on the longer-term business strategy and 
deliver consistent, well-aligned and transparent 
remuneration outcomes.

Thank you for your ongoing support  
of OZ Minerals.

2.0 Remuneration policy

2.1 Overview of remuneration policy and practices 
The remuneration principles (Table 2) demonstrate the links between remuneration and business strategies and their impact on  
OZ Minerals actual remuneration arrangements. The overriding business objective is to achieve superior returns compared to the 
Company’s peers in the resources sector.

Table 2 – Remuneration principles

Business needs and 
market alignment

Simplicity and equity

Performance and 
reward linkages

Market positioning  
and remuneration mix

Talent management 

OZ Minerals remuneration policy is focused on achieving our corporate objectives. Remuneration is set with regard to market 
practices and aligned with achieving shareholder returns.

OZ Minerals remuneration philosophy, policy, principles and structures are simple to understand, communicate and implement,  
and are equitable across the Company and its diverse workforce.

Well-designed remuneration policy supports and drives Company and team performance and encourages the demonstration of 
desired behaviours. Performance measures and targets are few in number, outcome-focused and customised at an individual level  
to maximise performance, accountability and reward linkages.

Fixed remuneration is set at a competitive level and positioned to take in to account the challenges of attracting and retaining 
high performers in business critical roles, particularly in the mining industry. The ‘at-risk’ components of remuneration depend on 
challenging goals and are focused on incentivising executive KMP to achieve business critical objectives and shareholder returns. 

Remuneration policy is tightly linked with our performance and talent management frameworks to reward and recognise employees 
who achieve their role accountabilities and to engage future leaders.

Governance, transparency 
and communication with 
shareholders

OZ Minerals is committed to developing and maintaining remuneration policies and practices that maximise value. We will openly 
communicate these to shareholders and other relevant stakeholders, and will always be within legal, regulatory and industrial 
requirements. The Board has absolute discretion to develop, implement and review key aspects of remuneration. 

2.2 Remuneration consultants
The Board of Directors and the People & Remuneration Committee seek and consider advice from independent remuneration consultants 
to ensure that they have all of the relevant information at their disposal to determine executive KMP remuneration. Remuneration 
consultant engagement is governed by internal protocols that set the parameters around the interaction between management and 
consultants to minimise the risk of any undue influence and ensure compliance with the Corporations Act 2001.

PROTO COLS
Under the protocols adopted by the Board and the People & Remuneration Committee:

 / remuneration consultants are engaged by and report directly to the Board or the People & Remuneration Committee

 / the committee must, in deciding whether to approve the engagement, have regard to any potential conflicts of interest including 

factors that may influence independence such as previous and future work performed by the Committee and any relationships that 
exist between any executive KMP and the consultant

 / communication between the remuneration consultants and executive KMP is restricted to minimise the risk of undue influence on 

the remuneration consultant

 / where the consultant is also engaged to perform work that does not involve the provision of a remuneration recommendation, 

prior approval of the Board or People & Remuneration Committee must be obtained in certain circumstances where 
the consultant continues to be engaged to provide remuneration recommendations.

The Board and the People & Remuneration Committee use remuneration consultants’ advice and recommendations from time to time.  
The Board makes its decisions after it considers the issues and the advice from the People & Remuneration Committee and consultants.

During 2018, Guerdons and PwC were engaged to review the Company’s executive remuneration framework and to assist with the 
implementation of the changes to the Executive Remuneration Framework outlined elsewhere in this report. The work completed did  
not constitute a remuneration recommendation in accordance with the Corporations Act 2001. The fee for work conducted by PwC was 
$99,465.3 (including GST) and the fee for work conducted by Guerdon was $98,381.4 (including GST). In addition, EY was engaged to 
undertake a market benchmarking review of executive remuneration. Their analysis was considered by the Remuneration Committee and 
the Board in forming their views on remuneration matters. The work completed did not constitute a remuneration recommendation in 
accordance with the Corporations Act 2001. The fee for work conducted was $72,512.0 (including GST).

2.3 Review of executive KMP remuneration
Executive KMP remuneration levels are reviewed annually by the Board with help from the People  
& Remuneration Committee and external remuneration consultants as required. The review makes sure 
that executive KMP remuneration remains consistent with the Company’s remuneration policies and 
guiding principles, and considers:

 / the Company’s remuneration policy and practices

 / relevant market benchmarks using salary survey data from the Australian industrial  

and resources sectors

 / the skills and experience required of each role in order to grade positions accurately  

and attract high calibre people

 /

individual performance against role expectation, set objectives, leadership behaviours  
and development plans

 / Company strategy, business plans and budgets.

2.4 Executive KMP remuneration components

Table 3 – Remuneration mix 

Total fixed remuneration (TFR)

The regular base reward that reflects the job size, 
role, responsibilities and professional competence 
of each executive, according to their knowledge, 
experience and accountabilities and considering 
external market relativities.

At-risk remuneration

Short term incentive (STI)

Long term incentive (LTI)

A variable, performance based, annual cash incentive 
plan designed to reward high performance against 
challenging, clearly defined and measurable objectives. 
These are based on a mixture of targets and are set to 
incentivise superior performance with specific targets or 
metrics in each category.
From 2019, STI will include an equity component.

The equity component of the at-risk reward opportunity 
which is linked to the Company’s medium to long 
term TSR and share price performance. A three-year 
performance period applies. 
From 2019, AISC will replace the share price  
performance measure.

The mix of fixed and at-risk remuneration varies depending on the role and grading of executives 
as well as the performance of the Company and individual executives. More senior positions have 
a greater proportion of at-risk remuneration. If maximum at-risk remuneration is earned, the ratio 
percentage of fixed to at-risk remuneration would be as follows.

Table 4 – Questions and answers about executive KMP remuneration

Total fixed remuneration (TFR)

What is included in total fixed remuneration?

When and how is fixed remuneration reviewed?

An executive KMP total fixed remuneration comprises salary and certain other benefits (including statutory 
superannuation contributions) that may be taken in an agreed form, such as cash, leased motor vehicles and 
additional superannuation, provided that no extra cost is incurred by the Company for these benefits.

Fixed remuneration is reviewed annually. Any adjustments to the fixed remuneration for the Managing Director 
and CEO and other executive KMP must be approved by the Board after recommendations by the People & 
Remuneration Committee. During the year, we also conducted market benchmarking of executive remuneration, 
mindful of the need to continue to retain our key employees in a competitive market as the Company grows.  
The benchmarking demonstrated that our fixed remuneration was, in most cases, in line with our preferred 
positioning, toward 50th percentile. 

Short term incentive (STI)

Why does the Board think an STI plan is appropriate?  Variable performance-based remuneration strengthens the link between pay and performance. The purpose of 

What are the performance conditions?

these programmes is to make a large proportion of the total market reward package subject to meeting various 
targets linked to OZ Minerals’ business objectives. The use of variable performance-based remuneration avoids much 
higher levels of fixed remuneration and is designed to focus and motivate employees to achieve outcomes beyond 
the standard expected in the normal course of ongoing employment. A reward structure that provides variable 
performance-based remuneration is also necessary as a competitive remuneration package in the Australian and 
global marketplace for executives.

The performance conditions that determined STI outcomes in 2018 were: (a) Company key performance indicators 
(KPIs) and (b) individual KPIs.
The Company KPI hurdle in 2018, accounted for 80% of the STI award for the Managing Director and CEO and 
50% of the STI award for other KMP and the balance was attributable to individual KPIs.

(a) Company KPIs
Company KPIs are set and weighted at the beginning of each year. They are designed to drive successful and 
sustainable financial and business outcomes, with reference to the Board approved corporate objectives, plans and 
budget for the year. The key areas of focus in 2018 included improving the Company’s operational and financial 
performance, sustainability performance and progressing strategic growth objectives.

b) Individual KPIs
Individual KPIs vary for each executive KMP based on their accountabilities. 
The Board assesses and sets the KPIs for the Managing Director and Chief Executive Officer award, and the 
Managing Director and Chief Executive Officer assesses and sets the KPIs for each of the other executive KMP in 
consultation with the Board. 

Is there an overriding financial performance  
condition or other condition?

Yes. The availability of the STI pool is at the discretion of the Board, which takes into account the interests of the 
Company and shareholders. The Board can choose not to pay or reduce the amount of the STI otherwise payable.

How is the STI structured to reward  
exceptional performance? 

The STI plan is designed to reward executive KMP at three pre-determined performance levels – threshold,  
target and maximum.

Threshold performance represents the minimum level of performance required for an STI award to vest.

Target performance

represents the achievement of planned or budgeted performance,  
set at a challenging level.

(b) Mr Rankmore continues to be employed by the Company, however as defined by Corporations Act (2001), ceased to be KMP 
effective 18 April 2018 due to being appointed to manage the integration of Avanco Resources in Brazil. 

The Managing Director and CEO assesses the business performance of executive KMP throughout the year for 
progress and improvement, to arrive at a summary assessment at year end for discussion with the People & 
Remuneration Committee and the Board. The Board also reviews the performance assessment of all executives 
who report directly to the Managing Director and CEO, with a view to understanding, endorsing and/or discussing 
individual circumstances, performance, leadership behaviours and future development. The People & Remuneration 
Committee and the Board assess the performance of the Managing Director and CEO against the performance 
targets and objectives set for that year.
The Board considers the method of assessing STI as described above to be appropriate as the Managing Director 
and CEO has oversight of their direct reports and the day-to-day function of the Company, whilst the Board and 
People & Remuneration Committee have overall responsibility for determining whether executive KMP have met the 
performance targets and objectives set for that year.

If an executive leaves OZ Minerals then the Good Leaver Policy may apply (subject to the executive’s contract) and, if 
the requirements are met, the STI may be granted on a pro rata basis in relation to the period of service completed. 
This is at the Board’s discretion and conditional upon the individual performance of the relevant executive.

The Company believes that a LTI plan can:
 / focus and motivate employees to achieve outcomes beyond the standard expected in the normal course of 

ongoing employment

 / ensure that business decisions and strategic planning take into account the Company’s long term performance
 / be consistent with contemporary remuneration governance standards and guidelines
 / be consistent and competitive with current practices of comparable companies
 / create an immediate ownership mindset among the executive participants, linking a substantial portion of their 

potential total reward to OZ Minerals’ ongoing share price and shareholder returns.

How is STI assessed?

What happens to STI awards when  
an executive ceases employment?

Long term incentive (LTI)

Why does the Board consider an  
LTI plan to be appropriate?

How is the award delivered? 

The LTI is granted using performance rights under the OZ Minerals LTI plan (detailed below).

Was a grant made in 2018?

A grant was made on 6 February 2018 to all continuing participants in the LTI plan, excluding the CEO whose grant 
was made on 24 April. The number of performance rights granted to each executive was calculated as their LTI 
dollar opportunity divided by the adjusted five-day volume weighted average price of OZ Minerals as at the start of 
the performance period. The performance period for the 2018 LTI grant is 1 January 2018 to 31 December 2020.

What was the value of the  
2018 grant for executive KMP?

What are the performance conditions?

The two performance conditions, referred to as the vesting conditions are: (a) the executive KMP meeting the service 
condition; and (b) OZ Minerals meeting the LTI performance conditions.

Service condition
The service condition is met if employment with OZ Minerals is continuous for three years commencing on or around 
the grant date (performance period).

Performance conditions
The LTI plan performance conditions for 2018 are the same as 2017 and are as follows:

1. Total shareholder return (TSR)
Relative TSR is the primary LTI performance hurdle measured against a comparator group. The Board considers TSR 
to be an appropriate performance hurdle because it ensures that a proportion of each participant’s remuneration is 
linked to shareholder value and that participants only receive a benefit where there is a corresponding direct benefit 
to shareholders.
TSR reflects benefits received by shareholders through share price growth and dividend yield and it is the most 
widely used long term incentive hurdle in Australia. The Company employs an independent organisation to calculate 
the TSR ranking to ensure an objective assessment of the relative TSR comparison. Performance rights in respect to 
this hurdle will vest in accordance with the following table.

Table 4.4 – Performance rights vested according to total shareholder return

of constituents of the nominated peer group

Between 50th percentile and 75th percentile (not inclusive)

75th percentile or above

100% 

The TSR performance hurdle accounts for 70% of the LTI award.

2. Absolute share price growth
Absolute share price growth is the second LTI performance hurdle. This hurdle will be satisfied if the OZ Minerals 
share price has increased by at least 20% over the performance period. Performance rights in respect to this hurdle 
will vest in accordance with the following table.

Table 4.5 – Performance rights vested according to absolute share price growth

OZ Minerals share price growth over 
the performance period

Proportion of performance rights 
that vest

Less than 20%

20% or greater

0%

100%

The absolute share price growth hurdle accounts for 30% of the LTI award.

It is standard market practice to link individual executive performance (including mandatory service periods) 
and Company performance to the vesting of performance rights. The conditions link executives’ retention and 
performance directly to rewards, but only where shareholder returns are realised. The focus on employee-held  
equity is also part of a deliberate policy to strengthen engagement and direct personal interest to achieve 
shareholders returns.

Why were the performance conditions chosen?

What is the comparator group?

The comparator companies selected for the 2018 LTI plan are considered to be alternative investment vehicles for 
local and global investors. They are impacted by commodity prices and cyclical factors in a similar way to OZ Minerals. 
The Comparator group is reviewed annually for market changes.

What happens to performance rights granted under 
the LTI plan when an executive ceases employment?

What happens in the event of a change of control?

Is there any ability for the Company to ‘clawback’  
LTI awards? 

Does the Company have a policy in relation to  
margin loans and hedging at risk remuneration? 

If the executive’s employment is terminated for cause, all unvested performance rights will lapse unless the Board 
determines otherwise. In all other circumstances, unless the Board determines otherwise, a pro rata portion of the 
executive’s performance rights, calculated by reference to the portion of the performance period that has elapsed, 
will remain on foot, subject to the performance condition as set by the Board. If and when these performance rights 
vest, shares will be allocated (or a cash equivalent amount will be paid) in accordance with the OZ Minerals’ Equity 
Incentive Plan Rules and any other conditions of grant.

In the event of a takeover or change of control at OZ Minerals, the Board has the discretion to determine that the 
vesting of all or some of the performance rights should be accelerated. If a change of control occurs before the 
Board has exercised its discretion, a pro rata portion of the performance rights will vest, calculated on the portion 
of the relevant performance period that has elapsed up to the change of control. The Board retains discretion to 
determine if the remaining performance rights will vest or lapse.

In the event of fraud, dishonesty, gross misconduct or material misstatement of the financial statements, the Board 
may make a determination that could include the lapsing of unvested performance rights, the forfeiture of shares 
allocated on vesting of performance rights, and/or repayment of any cash payment or dividends to ensure that 
no unfair benefit was obtained. A minor amendment was made to provide the Board with the flexibility to make 
adjustments to any awards granted under the STI or LTI plans in the event that there is a catastrophic safety or 
environmental event, in which an adjustment to executive bonuses is warranted.

Under the Company’s Securities Trading Policy, all executives, directors and officers are prohibited from entering into 
financing arrangements where the monies owed to the lender are secured against a mortgage over OZ Minerals’ 
shares. The Company’s Securities Trading Policy also prohibits executives and employees from entering into any 
hedging arrangement over unvested securities issued pursuant to any share scheme, performance rights plan or 
option plan.

2018 Alignment Plan

Why did the Board consider it necessary  
to create the 2018 Alignment plan?

The Alignment plan was designed to support the retention of key employees during the critical period of  
the development of Carrapateena.

How was the award delivered?

Was a grant made in 2018?

The 2018 Alignment plan was granted using performance rights under the OZ Minerals Alignment Plan  
(detailed below).

A grant was made on 13 March 2018 to all participants. The number of performance rights granted to each 
executive was calculated as 20% of their fixed remuneration divided by the adjusted five-day volume weighted 
average price of OZ Minerals as at the start of the performance period. The performance period for the 2018 
Alignment Plan was 1 January 2018 to 31 December 2019.

What was the value of the 2018  
grant for executive KMP?

effective 18 April 2018 due to being appointed to manage the integration of Avanco Resources in Brazil.

What are the vesting conditions?

The vesting condition for each grant is a service condition, to be employed by the Group on 31 December 2019 and 
has not given notice of intention to resign.

What happens to performance rights granted under 
the 2018 Alignment plan when an executive ceases 
employment?

If the executive’s employment is terminated for cause, all unvested performance rights will lapse unless the  
Board determines otherwise. In all other circumstances, unless the Board determines otherwise, a pro rata portion  
of unvested Rights will remain on foot subject to the original Vesting Conditions.

What happens in the event of a change of control?

In the event of a takeover or change of control at OZ Minerals, the Board has the discretion to determine that the 
vesting of all or some of the performance rights should be accelerated. If a change of control occurs before the 
Board has exercised its discretion, a pro rata portion of the performance rights will vest, calculated on the portion 
of the relevant performance period that has elapsed up to the change of control. The Board retains discretion to 
determine if the remaining performance rights will vest or lapse.

3.3 LTI performance and outcomes
Performance rights granted under the OZ Minerals LTI Plan are granted for no consideration. 
Performance rights carry no dividend or voting rights. One ordinary share in the Company will be 
allocated on vesting of a performance right. The vesting condition for each grant is the relative TSR 
performance and absolute share price growth of the Company over the relevant performance period. 
In general, the executive must also remain employed with OZ Minerals for a continuous period of three 
years from the grant date. Details of the prior awards for relevant executive KMP are set out in the 
Remuneration Report for the year in which they were granted.

Details of the performance rights held by executive KMP that vested or lapsed during the year are  
set out in Table 15. Additional details are set out in Note 11 to the Financial Statements.

3.4 2018 Alignment plan
Performance rights granted under 2018 Alignment plan are a one-off allocation for retention purposes.

Performance rights carry no dividend or voting rights. One ordinary share in the Company will be 
allocated on vesting of a performance right. The vesting condition for each grant is a service condition, 
where the executive needs to remain employed by the Group on 31 December 2019 and has not given 
notice of intention to resign.

The LTI awards on foot during the year (including those granted as part of the 2018 LTI and 2018 
Alignment awards) are detailed below.

(a) The minimum value of each grant is nil. The maximum value of grant is calculated by applying the highest price of OZ Minerals’ shares during the 

year to the rights issued during the year.

(b) The fair values were calculated as at the grant dates. In accordance with the requirements of applicable Accounting Standards, remuneration 

includes a proportion of the notional value of performance rights as compensation granted or outstanding during the year. The notional value of 
performance rights granted as compensation is determined as at the grant date and progressively allocated over the vesting period. The amount 
included as remuneration is not related to or indicative of the benefit (if any) that individual executives may in fact receive. The values were 
calculated by an external third party based on a Monte-Carlo simulation model.

(a) Annual leave has been separately categorised and is measured on an accrual basis and reflects 
the movement in the accrual over the 12 month period. Any reduction in accrued annual leave 
reflects more leave taken/cashed out than that which accrued in the period.

(b) Other benefits include the value (where applicable) of benefits such as compulsory annual 

health checks, car parking or other benefits that are available to all employees of OZ Minerals, 
and are inclusive of Fringe Benefits Tax where applicable. Other benefits paid to Mr Ranson in 
2018 include payment of relocation costs for Mr Ranson and his family from Perth to Adelaide.

(c) Represents the net accrual movement for Long Service Leave (LSL) over the 12 month period 

which will only be paid if Executive KMP meets the required service conditions. 

(d) Represents direct contributions to superannuation funds. Amounts greater than the maximum 

superannuation level have been paid and included in cash salary. 

(e) The fair values were calculated as at the grant dates. In accordance with the requirements of 
applicable Accounting Standards, remuneration includes a proportion of the notional value of 
equity rights compensation granted or outstanding during the year. The notional value of equity 
rights granted as compensation which do not vest during the reporting period is determined as 

at the grant date and progressively allocated over the vesting period. The amount included as 
remuneration is not related to or indicative of the benefit (if any) that individual executives may 
in fact receive. The values were calculated by an external third party based on a Monte Carlo 
simulation model.

(f) Appointed 22 January 2018. Pro-rata remuneration reflected.
(g) Mr Rankmore continues to be employed by the Company however as defined by Corporations 
Act (2001), ceased to be KMP effective 18 April 2018 due to being appointed to manage the 
integration of Avanco Resources in Brazil. Pro-rata remuneration reflected.

(h) The prior year comparative value of performance rights has been adjusted to include 

proportionate expense in relation to the 2015 & 2016 LTIP grants. As a result, the value of 
performance rights disclosed for Andrew Cole has increased from $135,731 to $621,591 and 
total remuneration from $1,513,346 to $1,999,206.  The value of performance rights disclosed 
for Mark Rankmore has increased from $66,357 to $195,103 and total remuneration from 
$671,777 to $800,523.

ANNUAL AND SUSTAINABILITY REPORT 20186.0 Non-executive Director remuneration
6.1 Non-executive Director remuneration policy
Non-executive Director (NED) remuneration is reviewed annually by the Board. NEDs receive a fixed fee 
remuneration consisting of a base fee rate and additional fees for committee roles.

Consistent with best practice, NEDs do not receive any form of equity incentive entitlement, bonuses, 
options, other incentive payments or retirement benefits. As approved at the OZ Minerals General 
Meeting on 18 July 2008, the maximum fees payable per annum is $2,700,000 in total. As highlighted 
in the 2017 report, during 2018 the Board undertook a benchmarking review and decided to increase 
the fees paid to Non Executive Directors and address anomalies as between committees. Fees had not 
been increased in six years during which the Company has grown in scope and complexity. The revised 
fees are set out below and came into effect on 1 September 2018.

meeting or otherwise in connection with the business or affairs of the Company, in accordance with 
the Company’s constitution. The Chairman of the Board does not receive additional fees for being a

8.0 Other transactions with executive KMP or NEDs
There were no loans made to executive KMP, NEDs or their related parties during the year. There were 
no other transactions between the Company and any executive KMP, NED or their related parties other 
than those within the normal employee, customer or supplier relationship on terms no more favourable 
than arm’s length.

9.0 Executive remuneration framework changes
The Board believes that executive remuneration is a key enabler of the delivery of the group’s strategy 
for the benefit of shareholders, customers, employees and our communities. During 2018, we 
undertook a review of executive remuneration, to ensure that the framework remains fit-for-purpose 
as OZ Minerals continues to grow. The result of that review suggested that OZ Minerals had an 
opportunity to create a greater alignment of executive pay outcomes with the shareholder experience 
and simplify a framework that executives perceived to be complicated and in many cases something 
they had limited ability to influence.

As a result, we have proposed some refinements to the framework in 2019 that better address our 
objectives of greater alignment between shareholder and executive. These changes will, if performance 
targets are met, put equity into the hands of executives earlier and require them to hold it for the long 
term, increasing the sense of ownership of the Company amongst our executives and encouraging 
decision making aligned to creating longer term shareholder value.

This framework also provides a simple, market-aligned approach which builds on our existing 
framework and meets our objectives of driving greater alignment between shareholders and  
executives. The changes are summarised in Table 16.

Why?

remuneration. We will continue to review our 
executive remuneration levels annually to ensure 
pay levels remain competitive to attract, motivate 
and retain the best talent for OZ Minerals.

Short term incentive

 / 30% of the STI award will now be paid in equity 

 / We wanted to increase the ownership mentality of our executive team by putting

lock and thereafter to minimum shareholding 
requirements. 

 / Increase maximum STI opportunity for KMP from 

80 to 100% and for CEO from 120–150%.

shares in their hands sooner than the current long term incentive program.
 / STI equity deferral is best practice across the resources sector and the broader 
Australian market, and it is a desire of the Board to reflect best practice in our 
remuneration arrangements.

 / Deferred STI allows us a reasonable timeframe to more effectively apply malus 
and ensure all awards reflect the true performance of an executive and the 
company, once the impact of all decisions is known.

Long term incentive

 / Replacing absolute share price performance 
measure with a strategic / financial measure  
based on All In Sustaining Costs (AISC).

 / We are also introducing a holding lock on the 
LTI plan, which will require executives to hold 
any vested LTI for a period of two years beyond 
the initial three year performance period and 
thereafter subject to minimum shareholding 
requirements.

Shareholder requirement

 / Introducing a requirement for executives to 

hold shares in the company. We are introducing 
minimum shareholding guidelines of 100% of 
fixed pay for the CEO and 50% of fixed pay for 
KMPs, to be accrued over a reasonable period.

 / The NEDs will also have the requirement to 

acquire shares in the company equal to 100%  
of their annual base fee over a five year period.

 / We are proposing to introduce a new measure into the LTI program  

associated with strategy to better align business and shareholder outcomes  
with executive pay outcomes, and provide a measure that executives are better  
able to influence. Maintaining costs in the bottom half of the cost curve will 
create long term shareholder value.

 / A two-year holding lock prevents senior executives who receive LTI shares after 
the three-year performance period from selling their shares for two years. This is 
firmly weighted towards driving long term sustainable strategic outcomes that 
deliver shareholder value.

 / Introducing a holding lock to the LTI further encourages our executives to  
create meaningful shareholdings in OZ Minerals, which is aligned to our 
objective of enhancing the way our reward arrangements align shareholder  
and executive interests.

 / The Board believes that this total five-year timeframe is sufficient to allow the 

full impact of executive decision-making to flow through to the share price, and 
thus directly align the wealth of the executive with that of shareholders.

 / By requiring executives to build and hold a meaningful shareholding in the 
company, we believe we will strengthen the alignment of executives with 
shareholders and foster longer term thinking.

 / Minimum shareholdings for directors reflect market practice and similarly  

create alignment.

ANNUAL AND SUSTAINABILITY REPORT 2018SUSTA INABI LI T Y 

REPOR T

Format 
We have been publishing our sustainability 
performance since 2008. Since 2016, we have 
published our sustainability performance in a 
combined annual and sustainability report to 
provide a transparent account of our approach  
to creating value in a financially, environmentally 
and socially responsible manner for our 
shareholders and other stakeholders. 

You’ll find examples of sustainability in practice 
embedded throughout the report to reflect how 
sustainability is integrated into our operations. 

Organisational boundary and scope 
We disclose sustainability data in accordance 
with Global Reporting Initiative (GRI) Standards. 
The GRI Standards are a comprehensive set 
of guidelines that cover all dimensions of 
sustainability. Further information is available  
on the GRI website. We also reference supporting 
documents which form part of our sustainability 
disclosure. These documents are publicly available 
on our website to make specific information  
more accessible. 

The Sustainability section covers the performance 
of our operations and facilities over which  
OZ Minerals had operational control for the 2018 
full calendar year. Joint ventures which we do not 
operate are excluded. In mid-2018, OZ Minerals 
acquired Avanco Resources Limited, a company 
with assets including an operating mine, in Brazil. 
The performance data of our Brazilian assets are 

not included in this year’s Sustainability Report, 
except where specifically noted, but we aim to 
report on their sustainability performance in the 
following year. Other sections within this report 
can provide metrics and data (e.g. TRIFR) which 
may include our Brazilian assets.

Assurance
OZ Minerals engaged KPMG to undertake  
limited assurance over selected information in  
this report. The full details of the process, scope 
of the assurance engagement and the outcome 
are detailed in KPMG’s assurance statement on 
page 88.

Materiality
We use a materiality assessment to determine 
key topics that matter most to our stakeholders 
and us. We assess sustainability topics based on 
two criteria: their importance to our business in 
terms of growth, economic and social impact; 
and their importance to stakeholders – including 
employees, governments, shareholders, investors 
and the community. High priority material 
topics are discussed in this report and further 
information on other sustainability topics is 
available on the OZ Minerals website.

We complied with the GRI guidance on materiality 
and completeness when identifying material 
topics and referenced a range of internal and 
external considerations and priorities. The process 
included extensive document review, surveys, and 
dialogue with internal and external stakeholders.

strategy

Our sustainability aspiration
Our aim is to be a global copper-focused modern 
mining company. We will deliver superior value 
across multiple operating assets underpinned  
by a diverse exploration and project pipeline.

business sustainably – operating 
ethically, safely, minimising our 
environmental footprint, ensuring 
we are well-governed and are 
socially responsible – core 
elements of creating value for our 
stakeholders, the heart of our 
company strategy.

How we do things is as important as what we do.  
Our culture and behaviours are framed by our  
How We Work Together principles. 

Delivery
We deliver on sustainability within OZ Minerals  
by focussing on value creation for our stakeholders 
and we report on our value creation achievements 
under the sustainability elements of Community, 
Environment, Safety and Health and Wellbeing. 
OZ Minerals ensures these accountabilities are  
met through our planning process and 
governance structure.  

Accountability
Assets are accountable for delivering the 
sustainability elements. At a corporate level, we drive  
and monitor our approach and outcomes through:

Strategy

Compliance

Annual review of strategy, setting  
of the annual business plan, and 
review and setting of policies and 
standards.

Monitoring sustainability  
performance at each asset via 
Performance Standards and 
Process Standards.

Risk register

Assets provide visibility of threats  
and opportunities via the risk register.

Governance
Oversight for sustainability is provided within  
the OZ Minerals governance framework.

performance rankings. It is released annually by 
S&P Dow Jones Indices and RobecoSAM to drive 
innovation in environmental, social and corporate 
governance (ESG) investment. We are committed 
to playing a leading role in corporate sustainability 
within our industry and our community. 

FTSE4Good 
FTSE Russell confirms that OZ Minerals Ltd  
has been independently assessed according  
to the FTSE4Good criteria and has satisfied the 
requirements to become a constituent of the

Sustainable Development Goals
In January 2016, 193 UN member states  
adopted 17 Sustainable Development Goals 
(SDGs). These goals and their related targets 
address the most important sustainability 
challenges and can stimulate worldwide

ANNUAL AND SUSTAINABILITY REPORT 2018Water 

Water is essential for our operations. Our 
water management includes many facets of 
environmental performance such as water use, 
tailings, climate change and water recycling.

Prominent Hill and Carrapateena are situated 
in areas with an average annual rainfall of less 
than 200 millimetres per year and depend on 
groundwater to sustain their operations. Our 
wellfields are located on nearby pastoral stations 
and, in the majority of cases, the pastoralists  
draw water from a shallower or discrete aquifer.  

Our water monitoring program involves 
measuring and monitoring water levels and 
quality in previously-agreed pastoral wells 
on neighbouring stations. Additionally, we 
closely monitor both the used and surrounding 
groundwater sources and report these results to 
the relevant stakeholders. We conduct sediment 
monitoring to detect any potential changes in 
downstream surface water quality from baseline 
values, including metal concentrations and 
acidity, to ensure our management measures are 
effective.

Climate change, energy use and greenhouse gas emissions

The majority of OZ Minerals’ energy use occurs 
at the Prominent Hill mine. The two main areas 
of energy consumption are the processing plant 
(electricity) and mining vehicles (diesel fuel). 
Prominent Hill’s mining activities transitioned to 
an underground-only mine during the year as the 
open pit reached the end of its life. As a result, 
there was a reduction in waste, fewer trucks  
were operating and less diesel was consumed. 
The Company’s energy demand will increase as  
the Carrapateena mine is developed, particularly 
once production begins (commissioning is 
scheduled for the fourth quarter of 2019). Both 
Prominent Hill and Carrapateena are connected 
to the South Australian electricity grid which is 
estimated to comprise approximately 40 per cent 
renewable energy.

We have reported energy use and greenhouse  
gas emissions in line with NGERS: 

 / Overall Scope 1 emissions decreased by 19% 

compared to the previous year. 

 / Overall Scope 2 emissions decreased by 5% 

compared to the previous year. 

 / 253,238 tonnes of Scope 1 and Scope 2 
carbon dioxide equivalent emissions were 

generated in total, a 11% reduction compared 
to the previous reporting year. 

 / Diesel use is Prominent Hill’s primary source  

of Scope 1 greenhouse gas emissions. 

 / OZ Minerals did not sell energy in 2018.

Taskforce on Climate-related  
Financial Disclosure 
The Financial Stability Board formed the Task  
Force on Climate-related Financial Disclosures 
(TCFD). It is a market-driven initiative which 
established recommendations for voluntary 
financial reporting on climate change risks.  
The Task Force released a recommendations  
report which provides the general framework  
for climate-related financial disclosures. 

In 2019, we will be developing a roadmap to 
integrate the TCFD recommendations into our 
annual disclosure. The TCFD recommendations 
provide a process to gain a better understanding 
of physical and financial climate-related threats 
and opportunities and reassess how climate 
change risks are integrated into our company 
standards and policies.

SUSTAINABIL ITY IN PR ACTICE

SUSTAINABLE WATER USE FO R CA RR APAT E EN A

OZ Minerals appreciates the critical importance of sustainable 
water management in the mining and resources sector. We have 
a strong commitment to research and trials that develop greater 
understanding of the role of water management, the opportunity 
to influence policy development on water in mining and inform 
the science and evidence base around water use and reuse.  
In the development of the Carrapateena Mine, we have focused  
on identifying and defining a sustainable water supply to meet 
the forecast demands of the site. Throughout 2017 and 2018,  
we conducted extensive water exploration drilling of the Northern 
Wellfield region, which is currently being further explored, from 
an advanced exploration viewpoint, to confirm the sustainable 
pumping rates of the identified wells. The Carrapateena project 
has been focused on utilising the underground mine water 
inflows to enable the application of sustainable practises for  
the Operation and to minimise impact on the wider region.

Air quality

The largest emission from the majority of our 
assets is dust. This is generated by stockpiling 
materials and vehicles moving over unsealed 
surfaces. We use a range of control measures to 
reduce the amount of dust we generate, including 
regular road maintenance, active dust suppression 
on roads and speed restrictions. Comprehensive 
sampling at Prominent Hill and Carrapateena 
has verified that our air quality management has 
effectively prevented adverse impacts on workers, 

the community and the environment. There 
are no ozone-depleting substances, persistent 
organic pollutants or stack emissions produced 
at Prominent Hill or Carrapateena. Air quality is 
also affected by sulphur and nitrogen oxides that 
are generated by burning fuels. Gases like carbon 
monoxide and oxides of nitrogen are generated 
during blasting.

Waste 

Mining waste is managed on site at the integrated 
waste rock landform (IWL) at Prominent Hill. 
This comprises the tailings storage facility (TSF) 
and two waste rock dumps. Over the reporting 
period, Prominent Hill produced 1.4 million 
tonnes of waste rock and 9.6 million tonnes of 
tailings. No potential acid-forming (PAF) material 
was mined. Most of the waste rock generated is 
placed in the rock dumps, with a proportion of 
non-acid forming (NAF) rock used to construct 
mine infrastructure, such as the tailings storage 
facility and roads. When PAF rock is encountered, 
it is encapsulated in designated PAF cells within 
the waste landform. These PAF cells are then 
encapsulated within NAF rock using physical 
control measures to prevent surface water runoff 
and subsequent environmental impacts.

Our tailings performance standard sets out 
our approach to managing waste within the 
TSF. These standards are written to ensure the 
TSF is designed, constructed and managed to: 
prevent seepage rates to groundwater; ensure 
that tailings are physically and chemically stable; 
protect terrestrial and avian life; and comply with 
regulatory and license requirements. The facility 
is run under a TSF Operations Management Plan 
which has been developed to comply with these 
standards. As a part of our tailings management, 
we conduct groundwater sampling to monitor 
parameters such as depth to water, salinity, pH, 
and metal concentrations at and surrounding the 
TSF and open pit. An external audit of the tailings 
dam at Prominent Hill is undertaken annually with 
a major audit undertaken every five years.

Land and biodiversity

In the development of the Prominent Hill Project, 
OZ Minerals committed to the establishment 
and management of a Significant Environmental 
Benefit (SEB) offset area. A parcel of land, 
consisting of a portion of the Mt Eba Pastoral 
Lease and the undisturbed areas within ML 6228, 
an area of approximately 12,415 ha, minus 
project-related disturbances. The two objectives 
of the SEB offset area are the management of the 
area to support habitat, by managing threatening 
processes during Prominent Hill operations, and 
the restoration of selected on-site areas, cleared 
to enable mining activities.

Flora and fauna monitoring of the SEB offset 
area commenced in 2006 and in over 10 years 
of continuous monitoring has identified the 
presence of three threatened species, the 
nationally threatened plains mouse and thick-
billed grasswren (eastern subspecies), both listed 
as vulnerable under the Environment Protection 
and Biodiversity Conservation Act (1999) and the 
chestnut-breasted whiteface listed as rare under 

the South Australian, National Parks and Wildlife 
Act (SA) 1972. All three species are also listed 
in the International Union for Conservation of 
Nature’s (IUCN) Red List of Threatened Species.

The extensive monitoring program has allowed 
the vegetation associations and preferred habitat 
of the three species to be mapped. Currently, 
annual vegetation monitoring is completed and 
is aimed at ensuring the health of the preferred 
habitat is maintained. Through management of 
the SEB offset area, OZ Minerals aims to protect 
and enhance habitat that is known to occur in  
the SEB offset area.

At Carrapateena, three IUCN species are listed 
within the area – two vulnerable species (the 
Malleefowl and plains rat) and one endangered 
species (the Pernatty knob-tailed gecko). The 
plains rat is the only species within the local area 
of proposed operations. Our monitoring continues 
to indicate that mining activities will have minimal 
impact on the surrounding natural environment. 

Rehabilitation and closure

The South Australian operations within OZ 
Minerals have documents and programs detailing 
closure, including the Supporting Works Plan  
and the Program for Environment Protection  
and Rehabilitation (PEPR). The Supporting  
Works Plan is reviewed annually to ensure closure 
assumptions are in line with current operational 
activities. The documents include rehabilitation 
and closure completion criteria to achieve post-
mining designated land use and to minimise 
environmental liability. Closure planning is 
updated throughout the operational life of  
a mine so that the risks and unknowns are 
identified and reduced over time. As part of 
this process estimated costs of rehabilitating, 
decommissioning and restoring the areas 

disturbed during the operation of the mine are 
evaluated and provided for. 

Progressive rehabilitation has been taking place 
at Prominent Hill. Rock armouring of the North 
Waste Rock Dump is now completed and the 
South Waste Rock Dump is near completed with 
the rock armouring of the TSF 75% completed. 

Stakeholder engagement on mine closure occurs 
throughout a mine’s life. The potential social 
and environmental impacts of mine closure are 
considered in our conversations with governments 
and local communities. We support community 
initiatives and sustainable local businesses as a 
part of our community engagement program.

SUSTAINABILITY IN P RACTICE

SUSTAINABLE WAS TE MANAG EME N T   
AT PRO MINENT HILL

Prominent Hill runs an extensive recycling program. This recycling 
program diverts many varying waste streams from landfill resulting 
in 50% of non-mining waste generated being either recycled or 
reused. In late 2018 a trial of biobin technology was implemented 
to further this philosophy. The biobins collect food waste generated 
by the Camp kitchen facilities within a sealed bin unit. This waste 
is then sent off site utilising courier backloads to Adelaide where 
it is processed into compost and fertilisers. This process has the 
additional benefit of providing the kitchen staff with a safer 
environment and reduces potential food sources for feral species.

ANNUAL AND SUSTAINABILITY REPORT 2018Safety culture and leadership

We understand that mining activities can 
impact people’s safety. As leaders, we actively 
care for everybody involved in our operations 
and supporting services. We’re committed to 
identifying, evaluating and managing all the 
associated threats for actual and potential  
adverse impacts as far as reasonably practicable. 

Our target is to achieve an injury and occupational 
disease-free workplace by ensuring hazards 
are identified and managed at the source. All 
safety incidents are thoroughly investigated, we 
share what we’ve learned, and we implement 
corrective actions. Safety data is collected for the 
entire workforce (employees, contractors, visitors 
working on our sites) and weekly reports are 
made to management, including the Managing 
Director and Chief Executive Officer. Performance 
is diligently monitored by our leadership team.

We conduct yearly internal audits against select 
company processes and standards, and external 
assurance as part of the annual Sustainability 
Report assurance process.

The number of recordable workplace injuries in 
many of our departments has been reduced due 
to active engagement from our senior leadership 
and activities focused on identifying and 
eliminating the causes of incidents. Significant 
incidents and incident trends are comprehensively 
reviewed by the Board’s Sustainability Committee 
to ensure that: we learn from incidents; our 
approved processes are complied with; and we 
implement additional controls where necessary.

Safety statistics are calculated per one million 
working hours. In 2018, the total recordable injury 
frequency rate (TRIFR) per million hours worked 
increased from 6.39 in 2017 to 7.24 in 2018.  
The TRIFR is exclusive of Brazil. 

Our lead indicators are monitored to reduce 
workplace hazards and injuries. Incidents are 
internally rated against potential or actual 
consequence and likelihood and assessed for their 
impact on safety, health, environment, community 
and financial metrics. This helps us to identify 
significant incidents that warrant in-depth review 
and analysis. All significant safety incidents are 
thoroughly investigated using the incident–cause–
analysis method. 

Significant incidents are those deemed to have:

 / high potential or actual serious consequences, 
or recordable incidences and disabling injury. 

We will roll out our process standards across  
all assets in 2019. The Risk Management 
Standard, and its supporting guidelines, is a 
critical document across the simplified process 
standards and its consequence table supports 
the Incident Reporting and Investigation 
Process Standard. The Incident Reporting and 
Investigation Process Standard sets out the 
process for identifying, elevating and reporting 
incidents, including safety-related incidents.

Safety programs

Effective safety management means that we:

 / provide a safe working environment with 

supportive processes and systems

 / empower our workforce to raise safety issues 

before there is potential for an incident

 / thoroughly investigate incidents when  

they occur

 /

implement controls to reduce the likelihood 
of recurring incidents using sound risk 
management practices. 

We have a number of initiatives in place to  
mature our safety culture. Our focus is on 
developing leadership to play an important part 
in our safety culture through demonstrating and 
promoting safety leadership in the workplace. All 
our employees and the employees of our contract 
partners are empowered to cease operations if 
necessary, to ensure the safety of the workforce. 

We are committed to preventing work-related 
injuries and illnesses. Our key safety programs 
such as the critical risk assurance program are 
underpinned by internal auditing of compliance 
against our safety performance standards 
and identifying opportunities for continuous 
improvement.

Contractor management

Our projects are delivered in partnership with 
contractors and suppliers and we rely in part on 
their capabilities to carry out our operations. Our 
management system defines the requirements 
and practices for working with contractors and 
suppliers. Major contractors sign agreements 
with requirements consistent with our Code of 
Conduct, policies and standards. They must share 
our values and exhibit behaviour that ensures the 
safety of the workforce. 

All contractors are subject to a pre-qualification 
process and are comprehensively evaluated 
against criteria including safety, health, 
environment and community aspects as well risk 
management, internal auditing processes and 
employee management. 

Minimum performance criteria (safety and 
environment) and performance criteria (including 
operating performance and site management)  
are developed and applied to our contracts. 

Training and emergency preparedness

We continuously explore and adopt methods 
to ensure we grow the capability of leaders 
and employees. Our crisis management plan 
outlines the roles, responsibilities and processes 
that our corporate crisis management team 
would follow in the event of a crisis. The team 
includes representatives from operations, legal, 
commercial, safety, environment, community, 
media and government relations. We define a 
crisis as an event that seriously threatens people, 

operations, assets, the environment or our 
long-term prospects and reputation. Our assets 
have specific emergency management plans that 
outline the response to be initiated in the event 
of an onsite emergency. We conduct scenario 
training with the operating assets’ management 
teams and the corporate crisis management 
team. We hold regular emergency exercises, 
both desktop and practical, to test the drills and 
exercises of our emergency preparedness.

Stakeholder engagement

We seek to build and maintain strong, supportive 
relationships with the host and local communities 
where we operate. Our assets have community 
engagement programs that include engagement 
with regulatory bodies, government agencies, 
communities, land owners, land connected 
Indigenous peoples and local landowners within 
the sphere of influence of the operations and 
project activities. This ensures input from the 
local community and government and provides 
the opportunity for us to understand the 
environmental, social and economic implications 
of our projects.

We also engage with key special interest groups 
and stakeholders who may potentially be affected 
by the asset’s activities to better understand the 
risks and social impacts. We provide accurate 
and relevant information in a timely manner and 
anticipate and proactively address community and 
stakeholder issues and concerns when consulting 
with them.

Mechanisms are in place to capture complaints 
and grievances and ensure they are promptly 
addressed. Our assets also monitor and review 
major communication and consultation activities 
to assess their effectiveness and promote internal 
and external stakeholder feedback.

All students in Australia, regardless of where 
they live, should be encouraged to pursue their 
educational goals. However, university research 
studies (National Centre for Student Equity in 
Higher Education) have indicated that a child  
born or living in remote Australia is only one  
third as likely to pursue higher education as 
a child born or living in a major city. Remote 
students often have unique knowledge, 
capabilities and perspectives that are a valuable 
part of a wider Australian culture. In recognition 
of this, Prominent Hill partnered with the Coober 
Pedy Area School in 2018 to work together in an 
effective and productive partnership in a program 
of activity called Aspirations and Pathways Project 
4 Youth (APP4Y). 

The objectives of this program are to:

 / assist in work experience through school 

incursion and excursion programs

 / assist in student aspirations by creating credible 

pathways for success

 / support education and development 

opportunities in the Science, Technology, 
Engineering and Math (STEM) areas.

Economic performance and socioeconomic contributions 

Operating a sustainable and economically 
successful company allows us to create  
economic value for our stakeholders.

We make significant contributions to local, 
regional and national economies directly 
through the payment of taxes and royalties to 
governments, income taxes, social investment, 
dividends as well as payments to our workforce 
and suppliers. In 2018 we:

 / paid more than $59.8 million in wages  

and benefits 

 / paid $67.6 million in dividends to shareholders

 / contributed $56.3 million in Government 

royalties. 

Activities at Prominent Hill and Carrapateena 
significantly contributed to local and regional 
economies, by $253.4 million in total. 
Operationally, significant value is generated 
through employment with our contracting 
partners and us, and investments in community 
development initiatives and programs. The direct 
benefits of our investments include improved 
infrastructure, health, safety awareness, education 
and training, and local business development.

ANNUAL AND SUSTAINABILITY REPORT 2018Tax transparency 

The Board of Taxation’s voluntary Tax Transparency 
Code (TTC) was endorsed by the Australian 
Government in 2016 and is designed to 
encourage greater transparency within the 
corporate sector of its compliance with Australian 
tax laws. OZ Minerals supports the initiative to 
ensure Australian businesses and subsidiaries of 
multinational companies operating in Australia 
pay tax on their Australian profits, as required 
under Australian tax legislation. 

leading to adverse reputational consequence, 
compliance with regulatory requirements and 
maximising shareholder value. OZ Minerals 
seeks to adopt a low tax risk position to ensure 
potential impacts to the Group are maintained 
at insignificant levels for tax exposures across its 
global business. Whilst OZ Minerals is entitled to 
certain tax concessions in the ordinary course of 
its business, it has no appetite to seek concessions 
that are motivated by the avoidance of tax.

OZ Minerals formally registered with the Board of 
Taxation’s TTC in 2018 and present the following

Local procurement

We seek to create sustainable benefits for the 
regions around our assets and source local 
employees and suppliers where possible. We 
preferentially purchase goods and services locally, 
within the region or within the state where we 
operate. National or international procurement 
is only considered when local procurement is 
not available or competitive. We also help local 
businesses to understand our pre-qualification 
processes and procurement standards. Local 
and Indigenous land connected peoples are 
encouraged to apply for positions and tender  
for business opportunities with our assets.

Our activities contributed $253 million to 
South Australian regional and local suppliers 
and contractors. These figures do not include 
wages and salaries paid to major contractors or 
expenditure by contractors in the local region.

Our greatest supply impact is through contracting 
mining and other services. The largest material 
inputs include diesel fuel, explosives, grinding 
media used in the processing plant, and cement 
used in the underground mine. These materials 
are sourced from large, reputable organisations 
with operations in Australia. 

Total spend on suppliers by region

The Antakirinja Matu-Yankunytjatjara Aboriginal 
Corporation AMYAC is the organisation of 
native title holders for the area encompassing 
a significant portion of the Far North of 
South Australia, including Coober Pedy and 
Prominent Hill. In 2015 OZ Minerals and AMYAC 
established A.M.Y Environmental Services Pty 
Ltd. (AMYES) a 100% AMYAC owned business 
at Prominent Hill. The result of the partnership 
was the establishment of an innovative and 
unique partnership with AMYAC, creating the 
organisation AMYES which laid the foundation 
for AMYAC to develop a waste management 
business, winning a successful tender to provide 
integrated Waste Management Services to 
Prominent Hill and to leverage long term business 
opportunities beyond the life of the Prominent  
Hill mine and outside of the resource industry 
and has illustrated the first step toward real social 
change for the traditional owner group. Since 
September 2015 AMYES has demonstrated a 
commitment to continuous improvement across 
all aspects of the business. This continuous 
improvement philosophy extends to the 
partnership model currently in place with  
OZ Minerals with the contract being renewed  
for another two years in 2018.

At the Carrapateena project, OZ Minerals has partnered with a local business organisation, 
Global Maintenance Upper Spencer Gulf (GMUSG), to drive local content activities and facilitate 
connecting local businesses to the Carrapateena project supply chain. 

The outputs of this process resulted in significant and measurable level of local content, measured 
as total firms involved and revenue generated. The local content model is transferrable to other  
OZ Minerals projects and operations.

OZ Minerals has been active in the community, holding a number of events to connect with local 
suppliers, including presentations at key regional conferences, facilitated lead contractor tours of

ANNUAL AND SUSTAINABILITY REPORT 2018Land-connected Indigenous peoples and cultural heritage

A genuine partnership with land-connected 
Aboriginal and Torres Strait Islander peoples is 
built on trust, respect and integrity. It allows us 
to build a common understanding and language, 
identify opportunities, learn from each other and 
work towards shared goals. A comprehensive 
understanding of the culture and social structure 
of host communities is required to ensure 
respectful, inclusive and effective engagement. 
Each asset has dedicated personnel to ensure 
regular liaison with Indigenous communities. 
The requirements regarding engagement with 
Indigenous communities are set out in the Land-
Connected Indigenous Peoples Performance 
Standard. In line with the Standard, each asset 
must operate in accordance with the principles  

of the UN Declaration of the Rights of Indigenous 
Peoples (UNDRIP). Our partnering approach  
with Indigenous peoples is based on principles  
of equality, transparency and mutual benefit.  
It respects and protects the rights of Indigenous 
peoples and is in line with the values of Free  
Prior and Informed Consent (FPIC). 

We provide cultural heritage and awareness 
training and information on how to avoid damage 
to cultural heritage, along with project obligations 
and requirements. Cross-cultural awareness 
training programs are offered to all contractors 
and employees and they are encouraged to 
attend. The training includes raising awareness on 
heritage and artefact finds and working in areas 
of cultural significance.

Human rights

Our internal governance is guided by international 
guidelines, such as the UN Guiding Principles 
on Business and Human Rights, United Nations 
Universal Declaration on Human Rights, 
Voluntary Principles on Security and Human 
Rights (VP), International Labour Organisations 
(ILO) Conventions and the International Council 
on Mining and Metals (ICMM) principles. We 
further reinforce our expectations of employees 
through our Code of Conduct. We have a variety 
of programs to promote a culture of compliance 

and ethical business. Asset induction training 
raises awareness of human rights responsibilities 
with senior management, employees, contractors 
(particularly security forces and human resources), 
and other stakeholders in the asset’s sphere of 
influence. From time to time, we also provide 
our employees with training on topics covered 
within the human rights standards. Maintaining 
and improving our systems and processes helps to 
ensure there are no human rights violations in our 
operations or in our supply chain.

Anti-bribery and corruption

We carried out an internal audit of OZ Minerals’ 
Anti-Bribery and Corruption Standard together 
with its processes and procedures. The internal 
audit involved a risk assessment, gap analysis, 
review of the anti-bribery and corruption 
compliance materials, and company integration 
of the compliance program, including within 

the newly acquired Brazilian assets. The primary 
purpose of the internal audit was to identify  
the bribery and corruption compliance risks  
OZ Minerals faces, how those risks are currently 
managed and what improvements could be made 
to the governance and compliance framework.

LONG T ERM PARTNER ING  FOR  N AT IvE   vEGETATIO N 

In 2018, OZ Minerals joined in a formal agreement with not-for-profit 
environmental organisation Nature Foundation in South Australia 
for significant environmental benefit. This innovative ten-year 
arrangement provides shared value for OZ Minerals and Nature 
Foundation. The partnership is forward looking and ensures a robust, 
long-term focus on environment protection and restoration, while 
also providing a platform for others to join us and contribute to native 
vegetation management. We have built a partnership model that 
creates value beyond the two organisations involved.

The long-term nature of the agreement allows OZ Minerals to meet 
our obligations to offset clearance of native vegetation – initially in 
relation to the Carrapateena Construction, Carrapateena Northern 
Wellfield and the Prominent Hill electricity transmission line, but with 
scope to add additional projects. Nature Foundation SA will ensure  
the protection and restoration of South Australia’s natural biodiversity 
with the certainty the long-term partnership and commitment that 
OZ Minerals provides.

SUSTAINABIL ITY IN PR ACTICE

WEST MUSGRAvE COLLABORATIvE   
INFRAST RUCTURE D ESIGN

Collaboration and knowledge sharing are critical to preventing 
and managing potential conflict whilst promoting opportunities 
for shared value. In 2018, the West Musgrave team worked with 
the Ngaanatjatjara Traditional Owners to undertake extensive 
cultural heritage survey assessments. The purpose of the cultural 
heritage survey works was to use local and traditional knowledges 
of the country to inform the design of the West Musgrave project 
footprint, including but not limited to the mining and non-processing 
infrastructure. By undertaking cultural heritage surveys prior to any 
early engineering or design works, the West Musgrave project has 
been able to incorporate the Traditional Owners’ cultural knowledge 
in order to respect and protect cultural heritage whilst providing the 
project with greater optionality and confidence on the options and 
opportunities around infrastructure development.

Health and wellbeing programs 

We have implemented a series of programs 
that promote, maintain and enhance a healthy 
lifestyle, in view of the impact of physical, mental, 
emotional and social health on overall employee 
wellbeing. Our fitness-for-work program includes 
a wide range of activities and education in fatigue 
management, employee assistance programs, 
role-based assessments, ergonomic assessments, 
fitness, and drug and alcohol programs. We 
intend to provide employees with the necessary 
education and information to self-manage their 
fitness-for-work. We have a fit-for-work alcohol 
and drug policy at all of our assets.

Mental health is an important health risk that 
continues to be a concern across the mining 
industry. We offer an employee assistance 
program (EAP) with free, professional and 

confidential counselling to all employees, 
contractors, and their immediate family members. 
The EAP is provided through a leading global 
health and wellness company and helps to 
address work or personal issues through a 
network of accredited counsellors. We have 
trained our first groups of mental-health first-
aiders at Prominent Hill and Carrapateena, and 
plans are in place to increase the number of 
trained personnel across our assets.

We offer an array of benefits to our employees 
including performance-based incentive plans, 
career development opportunities, paid parental 
leave and health and wellbeing services, such as 
health insurance, medical check-ups and health 
education programs.

Business ethics and ethical conduct training 

The Code of Conduct, the highest order of 
corporate governance, outlines the importance of 
– and OZ Minerals’ commitment to – maintaining 
an open working environment in which 
employees and contractors are able to report 
instances of unethical, unlawful or undesirable 
conduct without fear of intimidation or reprisal. 

OZ Minerals has appointed STOPline as the 
disclosure line to report unacceptable conduct 
confidentially and anonymously under the 
Whistleblower Policy. STOPline ensures best 
practice and the highest level of independence, 
as well as impartiality and confidentiality in the 
receipt and management of concerns relating to 
unacceptable conduct. STOPline offers a simple 
and highly confidential solution to the difficult 

issues of ethics, compliance, risk management 
and corporate governance.

Our mandatory online training courses reinforce 
our Code of Conduct and the information in our 
policies. We provide training and education on 
key legal and ethical risk areas. Our employees 
enrol in online learning courses that include our 
equal employment opportunity program and 
ethics and conduct program, as well as an anti-
harassment and bullying program. Each program 
includes awareness training based on site-specific 
needs. A new OZ Minerals online interactive 
induction program was launched during the year 
which further reinforces our Code of Conduct, 
policies and performance standards.

Training and education 

We offer a wide range of development 
opportunities, including formal programs, 
technical and compliance training, online 
learning and mentoring. This year our workforce 
undertook 27,767 hours of employee training, 
mostly at Prominent Hill and also at the 
Carrapateena project which is developing an 
operational workforce ahead of commissioning 
scheduled for Quarter 4 2019 where the majority 
of our employees are based.

Our modern mining culture underpins our 
approach to education and training with our 

How We Work Together Principles providing the 
foundation of how we conduct our activities. 
Leadership training is designed to build a more 
collaborative and innovative workplace supported 
by a flexible working environment. 

Specific training across the company spans 
inductions, safety, business ethics, specific 
role and development related education, and 
education and training designed to lift the 
capability of the workforce including leadership 
development.

ANNUAL AND SUSTAINABILITY REPORT 2018Diversity and inclusion

Women comprise 22 per cent of the workforce 
directly employed by OZ Minerals. Some individual 
contributors and functional leadership areas have 
more than 25 per cent female representation. 

We offer competitive remuneration for our 
employees that reflects the job type, years of 
experience, and the length of time employees 
have held their position. We review the earnings 
annually by gender and job band level to make 
sure that employee remuneration remains 
equitable and in line with market trends. 

All employees are entitled to parental leave. In 
2018, nine women and men took parental leave 

and nine returned to work after their parental 
leave had ended. A retention rate of 75 per cent 
was maintained after 12 months.

Twenty five per cent of our total workforce is 
covered by collective bargaining agreements. 

We value diversity in our workforce as it helps 
us to innovate and do things differently. We 
seek to create an inclusive work environment 
that encourages diversity, which in turn provides 
us with a strategic advantage that stems from 
applying a variety of capabilities, ideas and 
insights into problem solving and decision making.

OZ Minerals’ move to the Adelaide Airport business district in mid-2018 reflects our aspiration 
to be a modern mining company. A purpose-built, open-plan layout facilitates our flexible and 
activity-based working requirements, breaks down hierarchy, and promotes collaboration and 
innovation – key cultural aspirations supporting our modern mining company vision. 

Our new work environment is underpinned by our How We Work Together principles and 
enables more opportunities to connect with site-based employees. It also facilitates the right 
frame of mind for us to generate (and keep generating) imaginative solutions to enable our 
growth strategy. A modern facility supported by a modern mindset and work approach.

Conclusion

Based on the evidence we 
obtained from the procedures 
performed, we are not aware 
of any material misstatements

Criteria Used as the Basis of Reporting 
The criteria used in relation to the Annual Report content are the GRI Standards published by the 
Global Reporting Initiative (GRI) and Company specific definitions. 

Basis for Conclusion
We conducted our work in accordance with Australian Standard on Assurance Engagements ASAE 
3000 and ASAE3410 (the Standards). In accordance with the Standards we have:

 / used our professional judgement to plan and perform the engagement to obtain limited assurance 
that we are not aware of any material misstatements in the Selected Sustainability Information, 
whether due to fraud or error;

 / considered relevant internal controls when designing our assurance procedures, however we do 

not express a conclusion on their effectiveness; and 

 / ensured that the engagement team possess the appropriate knowledge, skills and professional 

competencies. 

Summary of Procedures Performed
Our limited assurance conclusion is based on the evidence obtained from performing the following 
procedures:

 / enquiries with relevant OZ Minerals Ltd personnel to understand the internal controls, governance 

structure and reporting process of the Selected Sustainability Information;

 / reviews of relevant documentation;

 / analytical procedures over the Selected Sustainability Information;

 / site visits to Corporate Head Office (Adelaide) and Carrapateena mine site;

 / walkthroughs of the Selected Sustainability Information to source documentation;

 / agreeing the Selected Sustainability Information included in the Annual Report to relevant 

underlying sources on a sample basis; 

 / an assessment that the indicators reported were in accordance with the GRI Standards; and

 / reviewing the sustainability section of the Annual Report in its entirety to ensure it is consistent 

with our overall knowledge of the Company.

How the Standard Defines Limited Assurance and Material Misstatement
The procedures performed in a limited assurance engagement vary in nature and timing from, and 
are less in extent than for a reasonable assurance engagement. Consequently the level of assurance 
obtained in a limited assurance engagement is substantially lower than the assurance that would have 
been obtained had a reasonable assurance engagement been performed. 

Misstatements, including omissions, are considered material if, individually or in the aggregate, they 
could reasonably be expected to influence relevant decisions of the Directors of OZ Minerals Ltd. 

Use of this Assurance Report
This report has been prepared for the Directors of OZ Minerals Ltd for the purpose of providing an 
assurance conclusion on the Selected Sustainability Information and may not be suitable for another 
purpose. We disclaim any assumption of responsibility for any reliance on this report, to any person 
other than the Directors of OZ Minerals Ltd, or for any other purpose than that for which it was prepared.

Management’s responsibility
Management are responsible for:

 / determining that the criteria is appropriate to meet the needs of intended users, being OZ Minerals 

Ltd and their stakeholders;

 / preparing and presenting the information subject to assurance in accordance with the criteria.  

This includes disclosing the criteria, including any significant inherent limitations;

 / establishing internal controls that enable the preparation and presentation of the information subject 

to assurance that is free from material misstatement, whether due to fraud or error;

 / advising us of any known and/or contentious issues relating to the information subject to assurance; 

and

 / maintaining integrity of the website.

Our Responsibility
Our responsibility is to perform a limited assurance engagement in relation to the Selected Sustainability 
Information for the year ended 31 December 2018, and to issue an assurance report that includes our 
conclusion.

Our Independence and Quality Control
We have complied with our independence and other relevant ethical requirements of the Code of Ethics 
for Professional Accountants issued by the Australian Professional and Ethical Standards Board, and 
complied with the applicable requirements of Australian Standard on Quality Control 1 to maintain a 
comprehensive system of quality control.

MINERAL 
RESOU RCES AND 
ORE RESERVES

Mineral Resources  
and Ore Reserves

OZ Minerals’ updated Minerals Resource and Ore Reserve estimates are released as of 30 June each 
year, or as necessitated by material changes to projects. Several additions were made to OZ Minerals’ 
portfolio throughout 2018, with the reporting of the initial Fremantle Doctor Mineral Resource estimate 
in the Carrapateena province. 

The joint venture with Cassini Resources reached another milestone with OZ Minerals earning 51% 
ownership of the project, introducing the Nebo-Babel and Succoth Mineral Resources in the West 
Musgraves province into the group reporting for the first time. 

Several Mineral Resource and Ore Reserve estimates were received as part of the Avanco Resources 
acquisition in mid-2018. However, these have not been restated in the Annual Report as they are 
currently under review as part of the integration process.

OZ Minerals’ Group Mineral Resource is estimated at 4.8 million tonnes of copper and 8.9 million  
ounces of gold. Group Ore Reserves are estimated at 2.1 million tonnes of copper and 3.1 million  
ounces of gold.

Summary of significant changes since 2017
There have been no changes to the Mineral Resource estimates of Carrapateena, Nebo-Babel and 
Succoth or the Carrapateena Ore Reserve estimate throughout 2018. 

Fremantle Doctor in the Carrapateena province released its initial Inferred Mineral Resource estimate  
in November 2018.

The Prominent Hill Open Pit Mineral Resource and Ore Reserves were fully depleted, with open pit  
mining operations completed in March 2018. 

Mining depletion of estimated underground Mineral Resources at Prominent Hill were offset by a lower 
reporting cut-off grade and through growth as a result of diamond drilling in the 30 June 2018 update. 
Surface ore stockpiles growth was wholly attributable to open pit mining. 

Depletion through underground mining was offset through ore reserve growth as a result of diamond 
drilling. Reflecting an improving geological confidence, the Proved Ore Reserve within the underground 
mining area has increased by approximately nine million tonnes, noting that the Probable Ore Reserve 
has decreased by this same amount.

ANNUAL AND SUSTAINABILITY REPORT 2018Notes to the consolidated financial statements  
Group performance

The principal business activities of OZ Minerals Limited (OZ Minerals or the Company) and its  
controlled entities (collectively the ‘Consolidated Entity’ or the ‘Group’) were the mining and  
processing of ore containing copper, gold and silver, undertaking exploration activities and  
development of mining projects. 

The Company is incorporated and domiciled in Australia and limited by shares which are publicly  
traded on the Australian Securities Exchange. OZ Minerals’ registered office relocated to  
2 Hamra Drive, Adelaide Airport, South Australia 5950, Australia, effective 22 June 2018. 

The Consolidated Financial Statements of OZ Minerals Limited and its controlled entities for the  
year ended 31 December 2018:

 /

include general purpose financial statements prepared by a for-profit entity in accordance with 
Australian Accounting Standards (AASBs) and the Corporations Act 2001, and comply with 
International Financial Reporting Standards (IFRS)

 / are presented in Australian dollars which is also the functional currency of its principal operations.  
The financial statements of the Company include consolidation of its subsidiaries referred to in  
Note 14, including entities acquired on acquisition of Avanco Resources Limited (Avanco).

 / have amounts rounded off to within the nearest million dollars to one decimal place unless otherwise 
stated, in accordance with Instrument 2016/191, issued by the Australian Securities and Investments 
Commission. 

The Consolidated Financial Statements have been prepared on a going concern basis and under  
the historical cost convention, except for the following items which are measured at fair value,  
or otherwise, in accordance with the provisions of applicable accounting standards:

 / financial instruments, including trade receivables

 / derivative financial instruments

 /

items of inventory and property, plant and equipment which have been written down in accordance 
with applicable accounting standards.

Other than the final dividend for the year ended 31 December 2018 as discussed in Note 4, no events 
have occurred subsequent to the reporting date which have significantly affected or may significantly 
affect the Consolidated Entity’s operations or results in future years.

The presentation of the Statement of Comprehensive Income has been changed to better represent 
how the business is managed. This change has no impact on the results. Now, financial information 
is aggregated according to function which gives a better representation of the financial performance 
of the Consolidated Group taking into account the acquisition of Avanco, the advanced stage of 
Carrapateena and an increasing operational focus. The presentation of the comparative period has  
also been changed to align with the new presentation. 

The detail of the reclassifications has not been disclosed as the presentation by nature cannot be readily 
mapped into function.

Brazil

Mining and processing high grade underground ore containing copper, gold and silver along  
with open pit ore from stockpiles. The Prominent Hill mine is located in the Gawler Craton 
of South Australia. The Prominent Hill mine generates revenue from the sale of concentrate 
containing copper, gold and silver to customers in Asia, Europe and Australia.

Exploration, evaluation and development associated with the Carrapateena project located in 
South Australia.

Exploration and evaluation activities associated with other projects, including exploration 
arrangements with Minotaur Exploration Ltd, Cassini Resources Limited, Mithril Resources,  
Red Metal, Acapulco Gold, Mineral Prospektering i Sverige, Woomera Exploration Ltd,  
Inversiones Mineras La Chalina S.A.C. and corporate development activities. 
The Company undertakes its own exploration on tenements around existing operating and 
development assets.

Mining and processing high grade open pit ore containing copper and gold at the Antas mine 
in Brazil. Antas generates revenue from the sale of concentrate containing copper and gold to 
customers in the United Kingdom, Europe and Asia. The company is undertaking exploration  
at CentroGold, Pedra Branca and Pantera.

Corporate  
(corporate activities)

Other corporate activities include the Consolidated Entity’s group office (which includes all 
corporate expenses that cannot be directly attributed to the operation of the Consolidated 
Entity’s operating segments), other investments in equity securities and cash balances.

Recognition and measurement of revenue 

The Consolidated Entity adopted AASB 15 during the year. The revised accounting policy in respect  
of revenue is set out below.

The Consolidated Entity generates sales revenue primarily from the obligation to transfer concentrate 
to the buyer and in some cases, based on the commercial terms of the contract, a secondary obligation 
to deliver it to the customer. Revenue is allocated between the performance obligations and recognised 
as each performance obligation is met, which for the primary obligation occurs when the concentrate 
is delivered to a vessel or location and for the secondary obligation, if applicable, when the concentrate 
is delivered to the customer’s location. Revenue arising from the secondary obligation is immaterial to 
the Group and aggregated with the primary obligation for disclosure purposes. The Group’s sale of 
concentrate incurs customary treatment and refining charges and other commercial costs consistent 
with industry practice. These items are in essence a deduction from the value of metal contained within 
the concentrate. These items are variable in nature and are accounted for as a deduction to revenue 
when they are recognised.

As is industry practice, the Consolidated Entity typically makes sales whereby the final sales price for 
the primary performance obligation is determined based on the market price prevailing at a date in 
the future. Revenue for the primary performance obligation is measured based on the fair value of 
the consideration specified in a contract with the customer at the time of settling the performance 
obligation and is determined by reference to forward market prices. Provisional pricing adjustments, 
which occur between the fair value at the time of settling the primary performance obligation and the 
final price, are also recorded within revenue. 

Gains and losses on hedge instruments related to sales contracts are also recorded in revenue and 
generally offset the movement as a result of provisional pricing adjustments.

A new segment ‘Brazil’ has been added to the Group with the acquisition of Avanco. Operating 
segments are components of the Consolidated Entity for which separate financial information is 
available and is evaluated regularly by the Consolidated Entity’s key management personnel to decide 
how resources are allocated and performance is assessed. As the Group now holds multiple operating 
assets in its portfolio, and in view of future growth plans in Australia and overseas, a re-evaluation of 
segment disclosure was undertaken to align with revised management reporting. This has resulted in a 
change to the disclosed financial metrics below. In accordance with accounting standards, comparative 
information has been reclassified in the same format.

Basic earnings per share is calculated by dividing the profit attributable to equity holders of OZ Minerals 
Limited, by the weighted average number of ordinary shares outstanding during the financial year.  
The weighted average is determined by the total number of shares on issue less treasury shares held  
by the Company throughout the period.

Diluted earnings per share adjusts the amounts used in the determination of basic earnings per share 
to take into account dilutive potential ordinary shares and the weighted average number of shares 
assumed to have been issued for no consideration in relation to dilutive potential ordinary shares.

ANNUAL AND SUSTAINABILITY REPORT 20183. Income tax
Income tax expense comprises current and deferred tax of the Consolidated Entity. Current and deferred 
tax expenses are recognised in other comprehensive income or directly in equity as is appropriate.

RECOvERABI LITY OF D EFERRED  TAX ASS ETS

The Consolidated Entity is subject to income taxes of Australia and jurisdictions where it has 
foreign operations. Significant judgement is required in the application of income tax legislation 
to determine the provision for income taxes. There are many transactions and calculations 
undertaken during the ordinary course of business for which the ultimate tax determination 
is uncertain, and for which provisions are based on estimated amounts. Where the final tax 
outcome of these matters is different from the amounts that were initially recorded, such 
differences will impact the current and deferred tax provision in the period in which the 
determination is made.

Assumptions about the generation of future taxable profits influence the ability of the 
Consolidated Entity to recognise (or continue to recognise) deferred tax assets. Taxable profit 
estimates are based on estimated future production and sales volumes, commodity prices,  
foreign exchange rates, operating costs, restoration costs and capital expenditure. A change  
in these assumptions may impact the amount of deferred tax assets recognised in the balance 
sheet in future periods.

Group taxation

The OZ Minerals Group principal operations are located in Australia and Brazil. Income tax expense, 
current tax and deferred tax balances have been determined based on the tax laws and tax rates 
applicable in the relevant jurisdiction.

OZ Minerals Limited and its wholly-owned Australian-controlled entities are part of a tax consolidated 
group. OZ Minerals Limited is the head company of the Australian tax consolidated group.

Recognised restricted tax losses are subject to an available fraction which limits the amount of these losses that can be utilised each year. 

Unrecognised tax losses
A review of unrecognised tax losses was undertaken during the year and as a result, additional 
restricted tax losses of $7.4 million tax effected (2017: nil) were recognised in the balance sheet. 
Restricted tax losses of $170.7 million tax effected (2017: $178.1 million tax effected) remain 
unrecognised in the balance sheet at 31 December 2018. Capital tax losses of $569.0 million  
tax effected (2017: $595.0 million tax effected) remain unrecognised in the balance sheet at  
31 December 2018.

Recognition and measurement of income taxes
Current tax

The tax currently payable is based on taxable profit for the year, using rates enacted or substantively 
enacted at the reporting date, and any adjustments to tax payable in respect of previous years.

Deferred tax 

Deferred tax assets and liabilities are determined using the balance sheet method which calculates 
temporary differences based on the difference between the carrying amount of the Consolidated 
Entity’s assets and liabilities in the balance sheet and their associated tax bases.

Deferred tax assets and liabilities are not recognised for temporary differences arising from investments 
in subsidiaries where the Consolidated Entity is able to control the reversal of the temporary differences, 
and it is probable that they will not reverse in the foreseeable future. Deferred tax assets are recognised 
to the extent that it is probable that future taxable income will be available to utilise them.

The carrying amount of deferred tax assets is reviewed at the end of each reporting date and adjusted 
based on estimates of future taxable income and/or capital gains against which the deferred tax asset 
could be utilised.

Deferred tax assets and liabilities are measured at the tax rates applicable to each jurisdiction which are 
expected to apply in the period when the assets are realised or liabilities discharged. They are offset 
where they relate to the same tax authority and there is a legally-enforceable right to offset.

4. Dividends
Since the end of the financial year, the Board of Directors has resolved to pay a fully-franked dividend 
of 15 cents per share on 26 March 2019. The record date for entitlement to this dividend is 12 March 
2019. The financial impact of the dividend amounting to $48.4 million has not been recognised in the 
Consolidated Financial Statements for the year ended 31 December 2018 and will be recognised in 
subsequent consolidated financial statements.

The details in relation to dividends announced or paid since 1 January 2017 are set out below:

NET REALISABLE vALUE OF INvENTORIES

Inventories are recognised at the lower of cost and net realisable value (NRV).

NRV of ore is based on the estimated amount expected to be received when the ore is  
processed and sold, less incremental costs to convert the ore to concentrate and selling costs. 
The computation of NRV for stockpiles involves significant judgements and estimates in relation 
to future ore blend rates, timing of processing, processing costs, commodity prices, foreign 
exchange rates, discount rates and the ultimate timing of sale of concentrates produced.  
A change in any of these critical assumptions will alter the estimated NRV and may therefore 
impact the carrying value of inventories.

An assessment of the NRV of non-current ore resulted in an adjustment to increase the value of 
inventory by $25.0 million in respect to low grade gold ore stockpiles being recognised in 2018  
(2017: $16.8 million). The increase is a reversal of a previous impairment.

Recognition and measurement of inventories
Inventory is valued at the lower of cost incurred to bring product to its present location and  
condition, and NRV.

Costs are assigned to individual items of inventory on the basis of weighted average costs. Costs 
comprise direct materials and labour and a proportion of overhead expenditure directly related to 
the production of inventories. Expenditure directly related to the production of inventories includes 
processing costs; transportation costs to the point of sale; and depreciation of plant, equipment,  
mining property and development assets, the latter of which includes deferred stripping assets and 
mine rehabilitation costs incurred in the mining process.

NRV is calculated by estimating the value that is expected to be realised upon sale of concentrate after 
deducting the estimated costs of processing and selling costs. This estimation is based on assumptions 
of future prices and costs as well as expected future ore blend rates and processing timing.

Inventories expected to be processed or sold within 12 months after the balance date are  
classified as current assets and all other inventories are classified as non-current.

Depreciation was $148.3 million for the year compared to $323.5 million in 2017. Depreciation expense 
decreased primarily due to the closure of the Prominent Hill open pit in the first quarter of 2018. 

Capital work in progress includes Carrapateena mine development costs including the original 
acquisition cost of $252.2 million. 

The original acquisition of Carrapateena provided for two further payments upon commercial 
production being reached: 

 / US$50 million on production of copper, uranium, gold or silver.

 / US$25 million on production of rare earths, iron or any other commodity.

The further payments amounting to US$75 million do not constitute a liability and are not recognised in 
OZ Minerals balance sheet because OZ Minerals has not reached the specified performance milestones 
on which payment is legally required.

Recognition and measurement of property, plant and equipment
Items of property, plant and equipment are stated at cost less accumulated depreciation and 
accumulated impairment losses. Cost includes expenditure that is directly attributable to the acquisition 
of the items and costs incurred in bringing assets into use. 

Expenditure associated with mining which relates to developing access to new sections of an ore body 
is capitalised as a mine development asset and depreciated on a units of production basis as ore is 
extracted. When ore extraction and mine development occurs concurrently expenditure is allocated 
between the cost of ore extraction (inventory) and mine development on the basis of the proportion  
of underlying activity typically meters advanced or material moved.

Mine property and development

Mine property and development includes mineral rights of $546.7 million (net of amortisation) associated with the acquisition of Avanco.

Mineral rights comprise identifiable exploration and evaluation assets, mineral resources and ore reserves which are acquired as part of  
a business combination and are recognised at fair value at date of acquisition. 

Mine property and development assets include costs transferred from exploration and evaluation assets once technical feasibility and 
commercial viability of an area of interest are demonstrable. After transfer, all subsequent expenditures to develop the mine to the 
production phase which are considered to benefit mining operations in future periods are capitalised. 

The proceeds from the sale of any concentrate produced from ore extracted and processed as part of development of the asset prior  
to being deemed ready for use are deducted from the cost of the asset, less any further processing and selling costs incurred. 

The present value of the expected cost of decommissioning an asset after its use is included in the cost of the respective asset if the 
recognition criteria for a provision are met.

Property, plant and equipment is tested for impairment when there is an indication of impairment. For the purposes of assessing 
impairment, assets are grouped at the lowest levels for which there are separately identifiable cash inflows. An impairment loss is 
recognised for the amount by which the asset or cash generating unit (CGU) carrying amount exceeds its recoverable amount.  
The recoverable amount is the higher of an asset’s fair value, less costs to dispose and its value in use. Assets that have been impaired  
are reviewed for possible reversal of impairment at each reporting date. 

Value in use is the net amount expected to be recovered through cash flows arising from continued use and subsequent disposal of  
an asset (or group of assets). In assessing value in use, estimated future cash flows are discounted to their present value using a pre-tax 
discount rate that reflects current market assessments of the time value of money and risks specific to the asset. 

The asset’s fair value less costs to dispose is the amount obtainable from the sale of an asset or cash-generating unit in an arm’s length 
transaction between knowledgeable and willing parties, less the estimated costs of disposal. 

A fair value measurement of a non-financial asset takes into account a market participant’s ability to generate economic benefits by using 
the asset in its highest and best use, or by selling it to another market participant that would use the asset in its highest and best use.

RECOvERABI LITY OF AS SETS

Cash generating units are tested for impairment when there is an indication that the CGU may be 
impaired. Examples of impairment indicators include the Group’s net assets exceeding its market 
capitalisation, unfavourable fluctuations in commodity prices and foreign exchange rates, or a 
decline in the CGU’s operating performance.

The Consolidated Entity undertook a review of the Prominent Hill, Carrapateena and the 
Carajas CGU’s to determine whether there was any indication that these CGU’s had suffered an 
impairment loss. The Consolidated Entity concluded that there were no such indicators that the 
CGUs were impaired at the reporting date noting also that the Carajas CGU was only recently 
acquired in an arm’s length transaction.

When the Group reviewed impairment indicators, consideration was given for negative trends 
in the significant judgements and assumptions that may impact the CGU’s valuation in future 
periods, including: 

 / expected future cash flows based on a range of factors including Board-approved internal 

budgets and forecasts which reflect expectations of resources and reserves; mine plans; short 
and long term commodity prices and foreign exchange rates; and operating and capital costs 

 / the value of mineral resources not modelled in Board-approved budgets, based on the use of an 
appropriate resource valuation multiple to the contained copper equivalent within the resources 
applicable to the CGU

 / the discount rate applied to the cash flows which reflects current market conditions. 

In addition, the Consolidated Entity monitors for impairment indicators by considering the impact 
of the above judgements and assumptions on the valuation of CGUs through periodic updates to 
its business valuation models.

Such assumptions are subject to variation as a result of changes in future economic and 
operational conditions. Consequently, the carrying value of the Consolidated Entity’s CGUs 
may differ in future years if assumptions made do not eventuate and actual outcomes are less 
favourable than present assumptions.

Depreciation of assets commences when the assets are ready for their intended use. The depreciation of 
mine property and development commences when the mine is commissioned or deemed ready for use. 

The residual values, useful lives and methods of depreciation of property, plant and equipment  
are reviewed at each reporting period and adjusted prospectively, if appropriate. Where depreciation 
rates are changed, the net written down value of the asset is depreciated from the date of the 
change in accordance with the new depreciation rate, with the change accounted for as a change in 
accounting estimate.

MIN ERAL RESOURCE A ND  ORE R ESERvE ESTIMATES

The estimated quantities of mineral resource and ore reserve estimates are based upon 
interpretations of geological and geophysical models and require assumptions to be made 
regarding exchange rates, commodity prices, future capital requirements and future operating 
performance.

Changes in reported mineral resource and ore reserve estimates can impact the carrying value 
of property, plant and equipment, including deferred mining expenditure; intangible assets; 
capitalised exploration; provisions for mine rehabilitation, restoration and dismantling obligations; 
and recognition of deferred tax assets as well as the amount of depreciation charged to the 
income statement.

Changes in the carrying value of the assets may arise principally through changes in the income 
that can be economically generated from each project. Changes in depreciation expense may 
arise through a change in the useful life over which property, plant and equipment is depreciated.

8. Provisions

MIN E REHABILITATION, RESTORAT ION  &  D IS MA N TL I NG   O B LI GAT IO N S

The provision for mine rehabilitation includes future cost estimates associated with reclamation, 
plant closures, waste site closures, monitoring, demobilisation of equipment, decontamination, 
water purification and permanent storage of historical residues. 

Uncertainty exists as to the amount of rehabilitation obligations which will be incurred due  
to the impact of environmental legislation changes and many other factors, including future  
changes in technology, price increases and changes in interest rates. The calculation of these 
provision estimates requires assumptions to be made as to: the application of environmental 
legislation, plant closure dates, available technologies, engineering cost estimates and discount 
rates. A change in any of the assumptions used may have a material impact on the carrying  
value of mine rehabilitation, restoration and dismantling provisions.

Recognition and measurement of provisions
Provisions are measured at the present value of the best estimate of the expenditure required to  
settle the present obligation at balance sheet date. The discount rate used to determine the present 
value reflects current market assessments of the time value of money and the risks specific to the 
liability. The increase in provisions due to the passage of time is recognised in the income statement  
as financing expenses.

1 1 4

ANNUAL AND SUSTAINABILITY REPORT 2018Provisions are made for the estimated cost of rehabilitation, decommissioning and restoration of 
areas disturbed during mining and exploration operations up to the reporting date for areas not yet 
rehabilitated. Provisions for mine rehabilitation are based on the current estimated cost to rehabilitate 
such areas, discounted to their present value based on expected future cash flows. The estimated  
costs include the current cost of rehabilitation necessary to meet legislative requirements. Changes  
in estimates are dealt with on a prospective basis as they arise. The provision is recognised as a liability, 
separated into current (estimated costs arising within 12 months) and non-current components based 
on the expected timing of these cash flows. 

Provision for demobilisation relates to the Consolidated Entity’s obligation to reimburse contractors  
for the cost of removing equipment from a mine site. Additions to the provision are made over the  
life of the equipment while in use at OZ Minerals to match the expected demobilisation costs with  
the related benefit.

The Company does not have authorised capital or par value in respect of its issued shares. Ordinary 
shares entitle the holder to participate in dividends and the proceeds on the winding up of the 
Company in proportion to the number of shares held. On a show of hands, every holder of ordinary 
shares present at a meeting in person or by proxy is entitled to one vote, and upon a poll each holder  
is entitled to one vote per share.

Recognition and measurement of issued capital
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.

Shares bought and held by the Employee Share Plan Trust to meet the Consolidated Entity’s obligation 
to provide shares to employees in accordance with the terms of their employment contracts and 
employee share plans as and when they may vest, are classified as treasury shares and are presented  
as a deduction from total equity, until the shares are cancelled or reissued.

The Consolidated Entity issued 23,535,081 shares to Avanco Resources Limited shareholders during 
2018 as a part of the purchase.

Issued ordinary share capital is classified as equity and is recognised at the fair value. Any transaction 
costs arising on the issue of ordinary shares are recognised directly in equity as a reduction of the  
share capital value on issue.

Recognition and measurement of share-based payments
The fair value of share-based payment transactions measured at grant date are recognised as an employee benefit expense with a 
corresponding increase in equity over the period during which the employees become unconditionally entitled to the instruments.  
If the employee does not meet a non-market condition, such as a service condition or internal KPIs, any cumulative previously  
recognised expense is reversed.

The fair value of the share-based payment transactions granted are adjusted to reflect market vesting conditions at the time of grant, 
and are not subsequently adjusted. Non-market vesting conditions are included in assumptions about the number of instruments that are 
expected to become exercisable and are updated at each balance sheet date. The impact of the revision to original estimates for non-
market conditions, if any, is recognised in the income statement with a corresponding adjustment to equity. Changes as a result of market 
conditions are not adjusted after the initial grant date.

ANNUAL AND SUSTAINABILITY REPORT 2018Risk management 

12. Financial risk management
OZ Minerals’ Group Treasury Function (Group Treasury) manages the financial risks of the Consolidated 
Entity. Group Treasury identifies, evaluates and manages financial risks in close co-operation with  
OZ Minerals’ operating units. The Board approves principles for overall risk management as well as 
policies covering specific risk areas, such as market, credit and liquidity risk.

This note presents information about the Consolidated Entity’s financial assets and liabilities, its 
exposure to financial risks, and its objectives, policies and processes for measuring and managing risks. 

The Consolidated Entity’s activities expose it primarily to the following financial risks:

 / commodity prices

 / foreign currency exchange rates

 / credit risk

 /

liquidity risk.

The Consolidated Entity holds the following financial instruments 

Carried at fair value using level  
one valuation technique (based  
on share prices quoted on the  
relevant stock exchanges)

Investments in equity securities

Carried at fair value using level two  
valuation technique (quoted market prices  
of copper, gold and silver adjusted for 
specific settlement terms)

Trade receivables
Derivative financial instruments

1 The carrying value of each of these items approximates fair value.

Carried at amortised cost1

Cash and cash equivalents
Other receivables
Trade payables
Other payables

Recognition and measurement
Financial assets and liabilities are recognised when the Consolidated Entity becomes party to the 
contractual provisions of an instrument.

Non-derivative financial assets

The Consolidated Entity classifies its financial assets as: 

 / financial assets at fair value through other comprehensive income

 / financial assets at fair value through profit and loss

 /

loans and receivables at amortised cost.

Financial assets measured at amortised cost are recognised initially at fair value plus any directly 
attributable transaction costs. 

Trade receivables, including those containing an embedded derivative, are carried at fair value. 

Concentrate sales receivables are recognised in accordance with the recognition and measurement 
criteria disclosed in Note one. Provisional payments in relation to trade receivables are usually due  
within 30 days from the date of invoice issue, with final settlement usually due within 60 days.  
Other receivables are recognised initially at fair value and subsequently measured at amortised  
cost using the effective interest method. 

The Consolidated Entity de-recognises a financial asset or a part of it when, and only when, the 
contractual rights to the cash flows from the financial asset expire or the financial asset is transferred  
to another party without retaining control or substantially all risks and rewards of the asset. On  
de-recognition of a financial asset, the difference between the carrying amount (measured at the date 
of de-recognition) and the consideration received (including any new asset obtained less any new 
liability assumed) and any cumulative gain or loss that had been recognised in equity is recognised in 
the income statement.

A financial asset measured at amortised cost is assessed at each reporting date as to whether there 
is any objective evidence of impairment as a result of one or more events having an impact on the 
estimated future cash flows of the asset.

An impairment loss in respect of financial assets measured at amortised cost is recognised in the income 
statement and is measured as the difference between the asset’s carrying amount and the present value 
of estimated future cash flows discounted at the asset’s original effective interest rate. The carrying 
amount of the asset is reduced through the use of an allowance account.

In the event that an impairment loss is reversed, the asset’s carrying amount cannot exceed what the 
carrying amount would have been had the impairment not been recognised. The amount of the reversal 
is recognised in the income statement.

Non-derivative financial liabilities

All financial liabilities are recognised initially at fair value and net of directly attributable transaction 
costs. Trade and other payables represent liabilities for goods and services provided to the Consolidated 
Entity prior to the end of the financial year which are unpaid. The amounts are non-interest-bearing, 
unsecured and are usually paid within 30 days of recognition. 

The Consolidated Entity de-recognises financial liabilities when its obligations are discharged,  
cancelled or expire. The difference between the carrying amount of the liability de-recognised  
and the consideration paid and payable is recognised in the income statement

Derivative financial instruments
Recognition and measurement

Derivative financial instruments are initially recognised at fair value on the date the derivative contract is 
entered into and are subsequently remeasured to their fair value at each reporting date. Changes in the 
fair value of any derivative instrument are recognised in the income statement or other comprehensive 
income, based the designation and effectiveness of the hedge instrument. 

Formal designation of the hedge and documentation of the relationship between the hedging 
instrument and the hedged item is finalised at the inception of the transaction.

Changes in the fair value of the derivative financial instrument, which has been designated in a 
hedge relationship, will be recognised in other comprehensive income if the hedging relationship 
remains effective and the underlying hedge item has not been recognised in the income statement, or 
recognised in the income statement if the hedge relationship is no longer effective or the underlying 
hedged item has been recognised in the income statement. Any ineffective portion of changes in the 
fair value of derivative financial instruments is recognised immediately in the income statement. The 
amount recognised in other comprehensive income is reclassified to the income statement in the same 
period as the underlying item is recognised in the income statement.

Commodity price risk management and sensitivity analysis
The Consolidated Entity is exposed to commodity price volatility on the sale of metal in concentrates 
such as copper and gold, which are priced on, or benchmarked to, open market exchanges.  
OZ Minerals aims to realise the prevailing forward copper price at the time of shipment of  
concentrates to customers which matches the quotation period of the underlying sale.

Gold derivative contracts

OZ Minerals has entered into gold forward contracts to manage its risk of fluctuations in cash flows 
arising from forecast gold sales in USD due to movements in gold prices and AUD:USD foreign 
exchange rates. The Company has designated these gold derivative contracts as cash flow hedges. 

The hedged gold sales represent around 62.6 per cent of forecast sales (gold oz.) in the period from 
2019 to 2021 and around 46 per cent of the gold contained in stockpiles at 31 December 2018.  
This programme is reviewed on a quarterly basis.

The forward contracts have been designated as cash flow hedges under AASB 9 and were assessed  
to be fully effective in managing the underlying risk. Accordingly, a tax-effected fair value reduction  
of $17.8 million was recognised in other comprehensive loss during 2018. At 31 December 2018, 
contracts for 238,057 ounces of gold were outstanding with an average strike price of $1,742 per 
ounce, as reflected in the chart adjacent.

HEDGE EFFECTIvENESS

A hedge relationship which is established at inception is assessed for effectiveness in managing 
the underlying risk. Where a derivative has expired or is assessed to be ineffective, all future fair 
value changes will be recognised in the income statement. Significant judgement is exercised 
regarding mine plans, sales forecasts and recoverable metal contained in mineral resources and 
reserves when determining a hedge relationship’s effectiveness.

Copper derivative contracts

The Consolidated Entity manages the exposure to copper price volatility on completed sales from 
contractual quotation pricing adjustments by entering into copper derivative contracts at the time of 
concentrate shipments. These fix the forward price at the time of shipment. These derivative contracts 
are designated as hedges and are recognised within the income statement as part of revenue. As a 
result of these hedges, the impact of changes in copper price after the date of sale on the income 
statement is expected to be negligible.

Commodity price sensitivity analysis

If copper prices were to vary significantly, then the expected impact on the income statement would 
be negligible due to the copper price hedging activity. As such, our analysis focuses on the impact 
of movements in gold prices as variations in silver prices have also been deemed immaterial for the 
purpose of this analysis (see table below). In accordance with Australian Accounting Standards, the 
sensitivity analysis is on all financial assets and liabilities deemed material to the Consolidated Entity.

A 10% movement in gold prices, which is based on reasonably possible changes over a financial year 
and reflects the variability management applies in forecasting sensitivity, results in $0.9 million after tax 
impact on the income statement on trade receivables balance of $70.9 million (2017: $121.9 million) 
and has a $2.3 million after tax impact on the derivative financial liability of $15.6 million (2017: $16.3 
million). In accordance with accounting standards, the impact has been calculated on the outstanding 
balance that is subject to commodity price risk and does not include the impact of the movement in 
commodity prices on the total revenue for the year.

Foreign currency exchange risk management and sensitivity analysis
The Consolidated Entity is exposed to foreign currency risk arising from assets and liabilities that are 
held in currencies other than the Australian dollar. 

The Group’s principal operations have a functional currency of Australian dollars. An entity’s 
functional currency is the currency of the primary economic environment in which the entity operates. 
Determination of an entity’s functional currency requires management’s judgement when considering 
a number of factors, including the currency that mainly influences revenue, costs of production, and 
competitive forces and regulations which impact on revenue. In addition, consideration must be given 
to the currency in which financing and operating activities are undertaken.

Foreign currency transactions are translated into the functional currency using exchange rates prevailing 
at the date of the transaction. Foreign exchange gains and losses resulting from the settlement of 
such transactions and from the translation at year-end exchange rates of financial assets and liabilities 
denominated in foreign currencies are recognised in the income statement. The carrying amount of the 
Consolidated Entity’s financial assets and financial liabilities by its currency risk exposure at the reporting 
date is disclosed below.

ANNUAL AND SUSTAINABILITY REPORT 2018At reporting date, if the foreign currency exchange rates strengthened/(weakened) against the 
functional currency by five per cent and all other variables were held constant, the Consolidated Entity’s 
after tax profit would have changed by $5.7 million and other comprehensive income would have 
changed by $0.5 million (2017: $5.7 million) after tax profit, $0.6 million other comprehensive income).
The sensitivity analysis includes only outstanding foreign currency denominated monetary items at the 
reporting date and adjusts their translation for a five per cent change in the foreign currency rate. 

Interest rate risk management and sensitivity analysis
The Consolidated Entity does not have any borrowings as at 31 December 2018 and therefore is not 
exposed to interest rate risk on borrowings. The Consolidated Entity carries term deposits with fixed 
interest rates. The effect of a change in interest rates at balance date would not have a significant 
impact on the after tax profit as all cash deposits have fixed interest rate terms.

Credit risk management
Credit risk refers to the risk that any counterparty will default on its contractual obligations  
resulting in financial loss to the Consolidated Entity. Counterparty credit risk arises through sales  
of metal in concentrate on normal terms of trade, cash deposits and derivative financial instruments. 

At the reporting date, the carrying amount of financial assets in the balance sheet represents the 
maximum credit exposure on cash and cash equivalents, trade receivables, other receivables and 
derivative assets. 

The credit risk on cash and cash equivalents is managed by restricting material financial transactions 
to banks which are assigned an S&P equivalent of A-1 short term credit ratings by international credit 
rating agencies and limiting the amount of funds that can be invested with a single counterparty in 
accordance with OZ Minerals’ Credit Risk Management Policy. 

Credit risk in trade receivables is managed by undertaking regular risk assessment and reviewing credit 
limits of customers. As there are a relatively small number of transactions, they are closely monitored 
to ensure risk of default is kept to an acceptable level. Sales contracts generally require a provisional 
payment of at least 90 per cent of the estimated value of each sale either promptly after vessel loading 
or upon the vessel arriving at the discharge port. Where appropriate, sales are covered by letter of credit 
arrangements with approved financial institutions.

Major customers who individually accounted for more than 10 per cent of total revenue contributed 
approximately 64 per cent of total revenue (2017: 75 per cent). These customers also represent  
88 per cent of the trade receivables balance as at 31 December 2018 (2017: 89 per cent). There were 
no instances of customer default during 2018 and there are no significant receivables which are past 
due at the reporting date. 

Credit risk on derivative financial instruments is managed by restricting material transactions only with 
counterparties who are at least category two members of the LME, or which are assigned an S&P 
equivalent of A-1 short term credit ratings by international credit rating agencies.

Liquidity risk management
Liquidity risk is the risk of encountering difficulty in meeting obligations associated with financial 
liabilities. OZ Minerals manages liquidity risk by conducting regular reviews of the timing of cash 
outflows and the maturity profiles of term deposits in order to ensure sufficient funds are available  
to meet its obligations.

The following table reflects all contractual repayments from recognised financial assets and liabilities 
at the reporting date, including derivative financial instruments. The market value is presented for

ANNUAL AND SUSTAINABILITY REPORT 201813. Contingencies

CONT INGENCIES

By their nature, contingencies will only be resolved when one or more uncertain future  
events occur or fail to occur. Determination of contingent liabilities disclosed in the financial 
statements requires the exercise of significant judgement regarding the outcome of future events. 
The financial results of OZ Minerals in future periods may be impacted unfavourably in the event 
of an unfavourable outcome of a number of matters outlined in this note.

Bank guarantees

OZ Minerals Group Treasury Pty Ltd has provided certain bank guarantees to third parties, associated 
with the terms of mining leases, power infrastructure contracts, exploration licences and office leases, 
in respect of which the relevant entity is obliged to indemnify the bank if the guarantee is called upon. 
At the end of the financial year, no claims have been made under any of these guarantees. The amount 
of some of these guarantees may vary from time to time depending upon the requirements of the 
recipient. These guarantees amounted to $209.1 million as at 31 December 2018 (31 December 2017: 
$52.9 million) and are backed by deposits. Presently, all guarantees are voluntarily cash-backed by 
deposits in order to reduce the bank fees payable but all funds can be withdrawn as and when required 
should the need arise.

Deeds of indemnity

The Consolidated Entity has granted indemnities under deeds of indemnity with current and former 
executive and non-executive directors, former officers, the former General Counsel–Special Projects,  
the former Group Treasurer and each employee who was a director or officer of a controlled entity of 
the Consolidated Entity, or an associate of the Consolidated Entity, in conformity with Rule 10.2 of the 
OZ Minerals Limited Constitution. 

Each deed of indemnity indemnifies the relevant director, officer or employee to the fullest extent 
permitted by law for liabilities incurred while acting as an officer of OZ Minerals, its related bodies 
corporate and any associated entity, where such an office is or was held at the request of the company. 
Under these indemnities, the company meets the legal costs incurred by company officers in responding 
to investigations by regulators and may advance funds to meet defence costs in litigation, to the extent 
permitted by the Corporations Act 2001 (Cth).

Warranties and indemnities

The company has given certain warranties and indemnities to the purchasers of assets and businesses 
that have been sold. Warranties have been given in relation to various matters including the sale of 
assets, taxes and information. Indemnities have also been given by the Consolidated Entity in relation  
to matters including compliance with law, environmental claims, a failure to transfer or deliver all assets, 
and payment of taxes.

Former Cambodian operations 

The Australian Federal Police (AFP) advised OZ Minerals in September 2014 that it was conducting an 
investigation of OZ Minerals’ 2009 acquisition of the remaining equity holding in the Okvau exploration 
joint venture in Cambodia in relation to foreign bribery claims. Since that time, the company has been 
advised by the AFP that the scope of the AFP’s investigation has been extended to OZ Minerals’ former 
Cambodian operations generally. OZ Minerals understands that the AFP is continuing its investigation 
and OZ Minerals is continuing to fully cooperate with the AFP. OZ Minerals has concluded that it is 
not probable that a present obligation exists and, accordingly, no provision has been recognised in the 
balance sheet at 31 December 2018.

Other

OZ Minerals Limited and its controlled entities are defendants from time to time in other legal 
proceedings or disputes, arising from the conduct of their business. OZ Minerals does not consider that 
the outcome of any of these proceedings or disputes is likely to have a material effect on the company’s 
or the Consolidated Entity’s financial position.

other information

14. Subsidiary acquisition 
The Consolidated Entity acquired Avanco during the year which has been accounted for as a business 
combination. The Consolidated Entity accounts for the acquisition of subsidiaries using the acquisition 
method of accounting on acquisition date by recognising the identifiable assets acquired and  
the liabilities assumed. OZ Minerals obtained control of Avanco Resources Ltd on 13 June 2018.  
OZ Minerals acquired 100% of Avanco Resources Ltd’s shares through an off-market offer made  
to shareholders and compulsory acquisition. 

The Avanco acquisition provides geographical diversification into new mineral provinces for OZ 
Minerals with a large copper gold mineral resource base in the Carajas. While the Antas operating mine 
immediately increases the Consolidated Entity’s production, the CentroGold, Pedra Branca and Pantera 
projects, along with other exploration prospects in the Carajas province (and the neighbouring Gurupi 
province), significantly enhance the growth pipeline and potential for near-term production growth.

Avanco’s assets and liabilities have been recognised at their provisional fair values as at 30 June 2018 
due to the proximity of the acquisition to 30 June 2018. The provisional recognition will be reviewed 
and finalised within 12 months of the acquisition in accordance with accounting standards, should any 
subsequent information provide better evidence of the fair values at the date of acquisition. If 100% 
interest in Avanco was acquired on 1 January 2018, the revenue of the Consolidated Entity would have 
been higher by $52.7 million and the profit after tax would have been lower by $4.9 million. 

Development of the CentroGold Project is subject to an injunction which presently restricts development 
activities. Legal processes are being followed to facilitate lifting of the injunction. 

As at 31 December 2018 the fair values recognised remain provisional pending completion of a review 
of the Antas open pit mine plan, Mineral resource estimates for the projects acquired and studies 
undertaken by the former management of Avanco. 

A. Consideration transferred

The consideration for each Avanco share was $0.085 cash and 0.009 OZ Minerals’ shares. During the 
year 100% of 2,615.6 million Avanco shares were acquired. As a result, $222.4 million was paid in 
cash to the shareholders of Avanco and OZ Minerals also issued 23.5 million shares, recognised at a 
weighted average price of $10.41 per share.

Acquisition-related costs of $5.9 million (net of tax) relating to due diligence, legal, transaction 
and consulting fees have been recognised under other expense in the Consolidated Statement of 
Comprehensive Income.

Fair value of assets and liabilities was measured on a provisional basis for the following amounts, 
pending completion of the final valuation:

 / Provisional fair value adjustment for property, plant and equipment includes the value of exploration 

assets and mineral rights which were acquired as part of the business combination and are recognised 
at estimated fair value as at the date of acquisition.

 /

Income and market techniques were used to estimate the fair value of property, plant and equipment 
and inventories having regard to expected net cash flows in future periods or, where applicable, the 
estimated market value of a specific asset.

 / The fair value of all other assets and liabilities were estimated by applying the cost technique which 

considers expected economic benefits receivable or probable economic outflows when due.

ANNUAL AND SUSTAINABILITY REPORT 2018Basis of consolidation
Investments in subsidiaries

Subsidiaries are those entities over which the Consolidated Entity is capable of exerting control.  
The Consolidated Entity controls an entity when it is exposed to, or has rights to, variable returns from 
its involvement with the entity and has the ability to affect those returns through its power over the 
entity. Where the Consolidated Entity holds less than a majority of the voting rights, other relevant 
factors are considered in assessing whether power over the entity exists. Factors considered include 
rights arising from other contractual arrangements, any contractual arrangements with other vote 
holders as well as the Consolidated Entity’s voting and potential voting rights.

The Consolidated Entity reassesses whether it controls an entity if circumstances indicate that there  
has been a change in one of the factors which indicate control. Subsidiaries are consolidated from  
the date on which control is assessed to exist until the date that control ceases. The purchase method 
of accounting is used to account for the acquisition of subsidiaries by the Consolidated Entity.

Intercompany transactions, balances and unrealised gains and losses on transactions between 
companies controlled by the Consolidated Entity are eliminated on consolidation. 

During the year the Consolidated Entity incorporated OZ Minerals Brazil (Holdings) Pty Ltd  
ACN 625 407 141 as a wholly-owned subsidiary on 5 April 2018. OZ Minerals Brazil (Holdings) Pty Ltd 
acquired Avanco Resources Limited (Avanco Group) by acquiring 100% of it’s issued share capital.

ANNUAL AND SUSTAINABILITY REPORT 201816. Deed of Cross Guarantee
The Company and all its Australian domiciled subsidiaries listed in Note 15 to the Consolidated  
Financial Statements, except for, OZ Minerals International (Holdings) Pty Ltd, ZRUS Holdings Pty Ltd 
and Avanco Group entities are party to a Deed of Cross Guarantee (‘Deed’). 

The effect of the Deed is that the Company guarantees to each creditor payment in full of any debt  
in the event of winding up of any of the subsidiaries under certain provisions of the Corporations  
Act 2001. If a winding up occurs under other provisions of the Act, the Company will only be liable in 
the event that after six months any creditor has not been paid in full. The subsidiaries have also given  
similar guarantees in the event that the Company is wound up.

Set out below is the Consolidated Statement of Comprehensive Income and Consolidated Balance

$4,377,379 to $4,991,985 to include the proportionate expense in relation the 2015 & 2016 LTIP grants.

Information regarding individual directors’ and executives’ compensation and some equity instrument disclosures as required by Corporations 
Regulation 2M.3.03 is provided in the Remuneration Report. 

Recognition and measurement of wages and salaries and short term  
employee benefits 
Liabilities for wages and salaries, including non-monetary benefits and annual leave expected to be 
settled within 12 months of the reporting date are recognised in the provision for employee benefits in 
respect of employees’ services up to the reporting date and are measured at the amounts expected to 
be paid, inclusive of on costs, when the liabilities are settled. 

Recognition and measurement of other long term employee benefits
Long term employee benefits include annual leave liabilities which are expected to be settled in the 
period greater than 12 months from balance date and long service leave liabilities. Other long term 
benefits are recognised in the provision for employee benefits and measured as the present value of 
expected future payments to be made in respect of services provided by employees up to the reporting 
date using the projected unit credit method. Consideration is given to the expected future wage and 
salary levels, experience of employee departures and periods of service. Expected future payments are 
discounted using market yields at the reporting date on national government bonds with terms to 
maturity and currency that match, as closely as possible, the estimated future cash outflows.

18. Related party transactions
A number of KMP, or their related parties, hold positions in other entities that may result in them having 
control or significant influence over the financial or operating policies of those entities. Where the 
Consolidated Entity transacts with the KMP and their related parties, the terms and conditions of these 
transactions are no more favourable than those available, or which might reasonably be expected to be 
available, on similar transactions to non-KMP related entities on an arm’s length basis.

20. New accounting standards
(i) Changes in accounting policies and mandatory standards adopted during the year

The accounting policies applied by the Consolidated Entity in these Consolidated Financial Statements 
are consistent with those applied by the Consolidated Entity in its Annual Report for the year ended  
31 December 2017 except for the application for the AASB 15 as described below. 

The Consolidated Entity has adopted all of the new, revised or amending standards that are mandatory. 
The Consolidated Entity has for the first time applied AASB 15 Revenue from Contracts with Customers 
with effect from 1 January 2018.

AASB 15 Revenue from contracts with customers
AASB 15 changes the timing (and in some case, the quantum) of revenue recognised from customers. 
Under the previous standard revenue for domestic sales is recognised when the concentrates are 
delivered to the customers’ premises, which is the point when the customer takes over the risk and 
rewards of ownership transfer. The Consolidated Entity’s assessment indicates that under AASB 15, 
revenue is continued to be recognised on the same basis when the customer obtains control of the 
concentrates.

Revenue for export sales was recognised when shipments of concentrates were loaded on to the vessel 
as the risk and reward of ownership was transferred to the customer at that point. The Consolidated 
Entity’s assessment under AASB 15 indicates that the export contracts are made up of two performance 
obligations. The first obligation is to deliver the concentrates to the port of shipment and the second 
obligation is to organise shipping of the concentrate, which will be satisfied when concentrates  
are delivered to the destination port. The Consolidated Entity assessed that revenue relating to the  
first obligation of delivery of the concentrates to the port of shipping will be recognised at that point 
and revenue relating to the shipping obligation will be recognised in future periods upon delivery  
of concentrates.

The impact of the change in accounting policy was accounted for using the full retrospective 
transitional provisions and did not have a material impact on the amount of revenue recognised as the 
transfer of risks and rewards under the previous AASB 118. Revenue coincides with the fulfilment of 
the performance obligation to transfer concentrate and revenue from freight services for cost, insurance 
and freight contracts is immaterial in the current and comparative periods.

1 3 4

ANNUAL AND SUSTAINABILITY REPORT 2018(ii) Early adoption of standards

The Consolidated Entity has not early-adopted any standards in the Annual Report during the year 
ended 31 December 2018.

(iii) Issued standards and pronouncements not early-adopted

At the date of authorisation of the Financial Statements, the following AASB Standards had been  
issued but were not yet effective. 

AASB 16 Leases
AASB 16 Leases eliminates the distinction between operating and finance leases and brings all leases 
(other than short term and low value leases) onto the balance sheet. A lessee recognises a right-of-use 
asset representing its right to use the underlying asset and a lease liability representing its obligation 
to make lease payments. The standard is applicable to annual reporting periods beginning on or after 
1 January 2019. The AASB 16 will result in higher assets and liabilities on the balance sheet and the 
cumulative effect of adopting AASB 16 will be recognised as an adjustment to the opening balance of 
retained earnings at 1 January 2019 with no restatement of comparative information.

The Consolidated Entity will recognise right-of-use assets and lease liabilities for the arrangements 
assessed as leases on transition unless they are short term, low value, or previously did not meet the 
definition of a lease for arrangements in place at 31 December 2018. AASB 16 will be applied to all 
new arrangements entered into from 1 January 2019. Many activities of OZ Minerals’ operations are 
conducted by contractors including mining, mine development, infrastructure and site services. Where 
contracts require payment of fixed charges that relate to use of equipment or property, they will be 
deemed to contain leases under AASB 16 and the present value of the fixed charges will be recognised 
as a right-of-use asset along with a lease liability. The nature of expenses relating to such fixed 
charges which would have been recognised as an expense attributable to the function, will change 
to depreciation for right-of-use assets and interest expense on lease liabilities. The variable charges 
required to be paid under the contracts will continue to be recognised as an expense in profit or loss 
or capitalised as incurred depending on the purpose for which the activity was undertaken.

The Consolidated Entity is currently undertaking an analysis of the financial reporting impact,  
noting that:

 / the group has not finalised the testing and assessment of all contracts, including contracts related  

to the recently acquired subsidiaries

 / the preliminary accounting policies remain subject to change and will be finalised and disclosed in  

its 2019 Half Year Financial Report along with initial application of the standard.

The Consolidated Entity is continuing its work on quantifying the impact of this standard.

Independent 
Auditor’s Report

To the shareholders of OZ Minerals Limited 
Report on the audit of the Financial Report

Opinion
We have audited the Financial Report of OZ Minerals Limited (the Company).

In our opinion, the accompanying Financial Report of the Company is in accordance with the 
Corporations Act 2001, including: 

 / giving a true and fair view of the Consolidated Entity’s financial position as at 31 December 2018  

and of its financial performance for the year ended on that date; and

 / complying with Australian Accounting Standards and the Corporations Regulations 2001.

The Financial Report comprises the:

 / Consolidated balance sheet as at 31 December 2018;

 / Consolidated statement of comprehensive income, consolidated statement of changes in equity,  

and consolidated statement of cash flows for the year then ended;

 / Notes including a summary of significant accounting policies; and

 / Directors’ Declaration.

The Consolidated Entity consists of OZ Minerals Limited (the Company) and the entities it controlled  
at the year end and from time to time during the financial year.

Basis for opinion
We conducted our audit in accordance with Australian Auditing Standards. We believe that the audit 
evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

Our responsibilities under those standards are further described in the Auditor’s responsibilities for the 
audit of the Financial Report section of our report. 

We are independent of the Company in accordance with the Corporations Act 2001 and the ethical 
requirements of the Accounting Professional and Ethical Standards Board’s APES 110 Code of Ethics  
for Professional Accountants (the Code) that are relevant to our audit of the Financial Report in 
Australia. We have fulfilled our other ethical responsibilities in accordance with the Code. 

Key audit matters
The Key Audit Matters we identified are:

 / Acquisition accounting for the purchase of Avanco Resources Limited and its controlled entities

 / Valuation of Low Grade Gold Ore Stockpiles 

Key Audit Matters are those matters that, in our professional judgement, were of most significance  
in our audit of the Financial Report of the current period. 

These matters were addressed in the context of our audit of the Financial Report as a whole, and  
in forming our opinion thereon, and we do not provide a separate opinion on these matters.

KPMG, an Australian partnership and a member firm of the KPMG network of independent member firms affiliated with KPMG International 
Cooperative (‘KPMG International’), a Swiss entity. Liability limited by a scheme approved under Professional Standards Legislation.

Acquisition accounting for the purchase of Avanco Resources Limited and its controlled entities

Refer to Note 14 to the Financial Report
The key audit matter

During 2018 the Consolidated Entity purchased Avanco Resources Limited and its 
controlled entities (Avanco).
Accounting for the purchase of Avanco is a Key Audit Matter due to the:
 / Size of the acquisition and therefore the impact on the Financial Report;
 / Significant judgement required to be exercised by the Consolidated Entity in 
determining the provisional fair value of acquired minerals rights, based on 
available information;

 / Complexity in accounting for deferred tax consequences arising on the acquisition;
 / Judgment required to be exercised by the Consolidated Entity in assessing the 
nature and amount recognised for obligations to make future payments based  
on income generated;

 / Uncertainties associated with the provisional acquisition accounting referred to  

in note 14; and

 / Complexity of disclosures required by accounting standards.

How the matter was addressed in our audit

Our procedures included:
 / Reading the Bidders Statement to understand the key terms and conditions;
 / Evaluating the methodology used for the acquisition accounting against accounting 

standard requirements and industry practice;

 / We focussed on the significant judgements made by the Consolidated Entity in 
assessing the provisional value of mineral rights classified within property plant  
and equipment. This included comparing the value of mineral rights recognised  
for each project to:

 / advice received from the Consolidated Entity’s external advisors in relation to 

the transaction; and

 / valuations published by brokers and analysts in order to determine whether the 
values recognised by the Consolidated Entity were within a reasonable range.

 / Evaluating the competence and objectivity of the Consolidated Entity’s  

external advisors and the extent to which information provided by them could  
be relied upon.

 / Evaluating the Consolidated Entity’s measurement of the deferred tax liability 
arising from the recognition of mineral rights against applicable accounting 
standards and appropriate technical interpretative literature.

 / Evaluating the status of outstanding matters to finalise the provisional acquisition 

accounting and whether any new information was available which required 
amendment to the provisional acquisition accounting at years end.

 / Assessing the disclosure in the Financial Report using our understanding  
of the acquisition, obtained from our testing, against the requirements of  
accounting standards.

valuation of Low Grade Gold Ore Stockpiles ($188.4m)

Refer to Note 5 to the Financial Report
The key audit matter

Significant judgment is required to be exercised by the Group in their assessment  
of the value of low grade gold ore which will be combined with copper ore to be 
mined in the future to produce concentrate. The valuation of low grade gold ore 
stockpiles is a key audit matter because significant judgment is required by us in 
evaluating the Group’s assessment of the value. The Group’s assessment is based 
on a model which estimates future revenue expected to be derived from low grade 
gold ore contained in existing ore stockpiles, less selling costs and further processing 
costs to convert ore into concentrate. We particularly focus on those judgments  
listed below which impact the valuation model:

 / Future metal production levels which are dependent on the volume and grade  

of existing low grade gold ore stockpiles.

 / Future processing costs of low grade gold ore, and related selling costs.

 / Future commodity prices and foreign exchange rates expected to prevail when 
the concentrate containing gold from existing low grade gold ore stockpiles is 
processed and sold.

 / The timing of production which depends on the available capacity of the mill.

How the matter was addressed in our audit

Our procedures included:

 / We tested the controls relevant to:

 / the Group’s valuation of low grade gold ore stockpiles, including board 
authorisation of key inputs to the assessment such as commodity prices, 
foreign exchange rates, and processing costs; and

 / the Group’s process for recording and monitoring volumes and grades of 
stockpiled low grade gold ore such as the use of quantity surveyors and 
management review and approval of grades. 

 / We assessed the methodology applied by the Group in determining the value of 
low grade gold ore stockpiles against the requirements of Accounting Standards 
for determining the net realisable value of inventories which are yet to be 
converted into finished goods.

 / We compared the results of quantity external surveyors to volume of low grade 

gold ore stockpiles.

 / We compared grades of stockpiled low grade gold ore to stockpiled low grade 

gold ore in previous periods, and against grades reported in the JORC Ore Reserves 
Statement.

 / We evaluated the Group’s key assumptions used to determine the value of low 

grade gold ore stockpiles by:

 / comparing forecast processing costs of low grade gold ore against historical 

actual processing costs to assess forecast processing cost assumptions;

 / assessing forecast selling costs by comparing to trends from existing customer 

sales contracts;

 / assessing commodity prices and foreign exchange rates applied by the Group 

against published analyst and broker data about commodity prices and foreign 
exchange rates expected to prevail in the future; and

 / checking that low grade gold ore was only forecast to be processed when 

there was capacity in the mill.

Auditor’s responsibilities for  
the audit of the Financial Report
Our objective is:

 / to obtain reasonable assurance about whether 
the Financial Report as a whole is free from 
material misstatement, whether due to fraud  
or error; and

Reasonable assurance is a high level of assurance, 
but is not a guarantee that an audit conducted 
in accordance with Australian Auditing Standards 
will always detect a material misstatement when 
it exists.

27 February 2019 

Misstatements can arise from fraud or error. They 
are considered material if, individually or in the 
aggregate, they could reasonably be expected to 
influence the economic decisions of users taken 
on the basis of the Financial Report.

A further description of our responsibilities for 
the audit of the Financial Report is located at the 
Auditing and Assurance Standards Board website 
at: www.auasb.gov.au/auditors_responsibilities/
ar1.pdf. This description forms part of our 
Auditor’s Report.

Report on the Remuneration Report

Opinion
In our opinion, the Remuneration Report  
of OZ Minerals Limited for the year ended  
31 December 2018, complies with Section  
300A of the Corporations Act 2001.

Directors’ responsibilities
The Directors of the Company are responsible 
for the preparation and presentation of the 
Remuneration Report in accordance with  
Section 300A of the Corporations Act 2001.

Our responsibilities
We have audited the Remuneration Report 
included within the Directors’ report for the  
year ended 31 December 2018. 

Our responsibility is to express an opinion on 
the Remuneration Report, based on our audit 
conducted in accordance with Australian  
Auditing Standards.

We draw attention to footnote (h) to Table 11 in 
the Remuneration Report, which describes the 
effect of the restatement of performance rights 
disclosed as comparatives. Our opinion is not 
modified in respect of this matter. 

Other Information
Other Information is financial and non-financial 
information in OZ Minerals Limited’s annual 
reporting which is provided in addition to the 
Financial Report and the Auditor’s Report. This 
includes the 2018 Snapshot, Message from the 
Chairman and CEO, OZ Minerals’ Company 
Strategy, Prominent Hill Operating Overview, 
Carrapateena Operating Overview, Musgrave 
Province Operating Overview, Brazil Operating 
Overview, Exploration and Growth Overview, 
Governance, Directors’ Report, Financial 
Review, Remuneration Overview, Sustainability 
Report, Mineral Resources and Ore Reserves, 
and Shareholder Information. The Directors are 
responsible for the Other Information. 

Our opinion on the Financial Report does not 
cover the Other Information and, accordingly, we 
do not express an audit opinion or any form of 
assurance conclusion thereon, with the exception 
of the Remuneration Report and our related 
assurance opinion.

In connection with our audit of the Financial 
Report, our responsibility is to read the Other 
Information. In doing so, we consider whether the 
Other Information is materially inconsistent with 
the Financial Report or our knowledge obtained 
in the audit, or otherwise appears to be materially 
misstated.

We are required to report if we conclude that 
there is a material misstatement of this Other 
Information, and based on the work we have 
performed on the Other Information that we 
obtained prior to the date of this Auditor’s Report 
we have nothing to report.

Responsibilities of the Directors  
for the Financial Report 
The Directors are responsible for:

 / preparing the Financial Report that gives  
a true and fair view in accordance with  
Australian Accounting Standards and the 
Corporations Act 2001;

 /

implementing necessary internal control to 
enable the preparation of a Financial Report 
that gives a true and fair view and is free from 
material misstatement, whether due to fraud 
or error; and

 / assessing the Consolidated Entity’s ability to 

continue as a going concern and whether the 
use of the going concern basis of accounting 
is appropriate. This includes disclosing, as 
applicable, matters related to going concern 
and using the going concern basis of 
accounting unless they either intend to liquidate 
the Consolidated Entity or to cease operations, 
or have no realistic alternative but to do so.
