Dear shareholders, 

We are pleased to present OZ Minerals’  
Annual and Sustainability Report for 2019. 

As with previous years, we have provided an 
overview of our financial and non-financial 
performance to holistically look at value creation 
for our stakeholders – employees, communities, 
governments, shareholders and suppliers –  
over the past year and looking ahead to 2020. 

This report will provide insight into our strategy, 
governance, performance and prospects, as we 
move from being a single mine, Australian-based 
business, to a global Modern Mining Company 
with three operating assets and a strong pipeline 
of growth options.

Going beyond what’s possible  
to make lives better
Over the past three years we have progressed 
our growth strategy, more than doubling the 
number of operating mines, our share price and 
our workforce. During this period many people, 
including Board members and employees, joined 
OZ Minerals because they identified with our 
culture, how we do things and what we stand for. 

With this insight into what makes OZ Minerals 
distinctive, we jointly created our Purpose – 
Going beyond what’s possible to make lives 
better.

More than a tagline, it shows how we intend  
to evolve, transform and be a part of something 
greater than ourselves. It brings meaning and 
direction to our work, as we use it to test 
ourselves at every level of what we do. 

We continued to strengthen our business focus 
through refining our strategy and developing  
a framework to show how various parts of  
OZ Minerals fit together. The framework includes 
our Purpose, our desire to be a Modern Mining 
Company and our Strategy to create value for 
our five stakeholder groups and is known as  
The OZWay (page 6).

Safety at OZ Minerals
As our business continues to grow, safety 
remains our priority at OZ Minerals and is an 
integral part of everything we do. Our overall 
total recordable injury frequency rate (TRIFR)  
was 6.27 compared to 7.52 in 2018. The 2019 
TRIFR of 6.27 includes unaudited figures from 
Brazil. Excluding Brazil, the TRIFR rate for 2019 
was 7.52.

During the year, we were saddened and 
confronted by a fatal incident involving an 
ElectraNet sub-contractor, who was a helicopter 
pilot working on stringing the power line to 
our Carrapateena project. His death has had 
a profound effect on the whole Company, 
especially the Carrapateena team.

Building a strong foundation  
for future growth
Our devolved organisational structure  
has enabled: 

 / continued focus on sustained reliable 

performance at the Prominent Hill mine, 
which has ongoing life extensions anticipated 
and a significant existing resource to support 
expansion studies

 / construction of the Carrapateena mine, with a 
shorter, 12-month ramp up to full production 
rates now being targeted following first 
concentrate production in December 2019 

 / development of the Carajás Hub strategy 
in Brazil with construction having started 
in December 2019 on the Pedra Branca 
underground mine which will become the  
first spoke in the Carajás Hub

 / development of a series of strategic 

agreements with Vale to advance our low  
risk, modest capital Carajás Hub strategy

 / the consolidation of and embedding of  
our culture and governance processes. 

We furthered the breadth and depth of 
experience of the Board as we welcomed 
Richard Seville as a new Non-executive Director. 
Richard’s suite of skills includes extensive mining 
experience, much of it in South America, as 
well as executive management experience and 
entrepreneurial and commercial skills.

We also appointed an in-country Advisory 
Board in Brazil, comprised of several high calibre 
Brazilian leaders from various sectors to provide 
additional strategic depth as we implement a 
low risk, modest capital, hub strategy in the 
Carajás and Gurupi Provinces. 

Partnering for innovation and agility 
As a Lean organisation we believe Partnering  
will help us achieve transformative change. 
Over the last year we have taken the first steps 
towards building true partnerships. Some of 
these partnerships were unique, because of  
who we partnered with. 

The Explorer Challenge in  
partnership with Unearthed 

Working with Unearthed, an energy and 
resources open innovation platform, to find  
new approaches and ways of working to drive 
up the discovery rate of economic mineral 
deposits, and speed up the exploration lifecycle 
for a more sustainable and efficient future for 
mineral exploration.

OZ MINERALS05

OZ Minerals Stakeholder Day

A joint OZ Minerals Stakeholder Day 
brought together a cross section of people 
from very different backgrounds, but  
with a shared interest in working with  
OZ Minerals to showcase, learn and  
reflect on ways to create shared value.

Strategic agreements with Vale

Working with Vale, Brazil’s largest miner 
and Carajás tenement holder, we have  
put in place a series of agreements to 
advance our low risk, modest capital 
Carajás Hub strategy in Brazil. This series 
of interlinked strategic agreements with 
Vale will simplify activities and enable 
OZ Minerals to draw on Vale’s extensive 
transport and logistics network, utilise 
their processing facilities and access small 
to medium high-grade Vale exploration 
projects in the Carajás region. 

A multi-site exploration  
alliance with Red Metal Limited

OZ Minerals entered an exploration alliance 
with Red Metal Limited, a junior explorer, 
which has increased our exploration 
footprint in Australia. The alliance gives us a 
two-year option to fund a series of mutually 
agreed, proof-of-concept work programs on 
six of Red Metal’s early-stage projects.

Responsible and  
sustainable investment 
Awareness and action on climate-related 
opportunities and threats are increasing 
rapidly in the resources sector and more 
broadly. 

With a view to creating more sustainable 
operations, we have developed a roadmap 
to manage climate-related opportunities 
and threats based on the Task Force on 
Climate-related Financial Disclosures (TCFD), 
the market-endorsed, internationally 
recognised framework for disclosure. 
Actions outlined in our roadmap are 
intended to embed climate-related risk 
within The OZWay and progressively expand  
our performance and overall approach, 
creating value for all stakeholders. 

A robust balance sheet supported by 
strong financial results enabled continuing 
investment into growth activities,  
$74.3 million in dividends to shareholders 
and a cash balance of $134.0 million. The 
Board has declared a total, fully-franked 
dividend for 2019 of 23 cents per share, 
made up of a half year payment of 8 cents 
per share and an end-year payment of  
15 cents. 2019 earnings per share  
totalled 50.7 cents.

We are optimistic about what can be 
achieved together with our employees, 
communities, governments, shareholders 
and suppliers in the coming year. 

Our achievements of today and tomorrow 
are built on your support and we are 
honoured to lead OZ Minerals, a Modern 
Mining Company.

2020 Priorities 

Global growth in 2019 recorded its  
weakest pace since the global financial 
crisis a decade ago, as rising trade barriers 
and the associated uncertainty weighed 
on business sentiment and investment 
activity. Despite this, the long-term 
outlook for copper remains attractive due 
to its importance in enabling economic 
development and emerging technologies. 
Building on the momentum of this outlook, 
OZ Minerals delivered on our Strategy in  
the past year and achieved an upward 
growth trajectory. 

We are now at a point where our efforts in 
2020 will be focused on consolidating and 
strengthening our current position. This will 
support the delivery of our future growth 
ambitions in the coming years. We will do 
this by:

 / strengthening our approach to safe  

work in all our operations 

 / progressing the implementation of  

our TCFD Roadmap

 / delivering reliable and consistent  

asset performance 

 / ramping up towards full production  

at Carrapateena

 / optimising our future growth pipeline 

through our province approach, 
expansion studies at Prominent Hill and 
Carrapateena, and exploration joint 
ventures

 / fostering innovation and collaboration 

through strategic partnering

STRATEGY – THE OZWAY
STRATEGY – THE OZWAY

Strategy – 
The OZWay

We are a Modern Mining Company that has grown over the past 
three years. To ensure all the people we interact with understand 
us, we have developed The OZWay – a simple model that explains 
how all the parts of OZ Minerals fit together. At the centre is our 
Strategy and wrapping it together is our Purpose – Going beyond 
what’s possible to make lives better.

Here is an explanation of each of the elements in The OZWay.

Our Context is what happens in the world 
around us. As a Modern Mining Company, with 
a focus on Global Copper, we are agile to the 
changes in our Macro Environment and we listen

Regulations in the places we work.

Our Choices define who we want to be. Our 
“how” focussed Strategy guides our priorities 
and together we agree on the Risk Appetite that 
we work within. Everything we do is about value 
creation and our Policies talk about how we 
do that in the different cultures and conditions 
where we work. Our Code of Conduct provides 
for a culture of inclusion where motivated 
people act ethically and responsibly. Our 
behaviours and principles are lived through  
our How We Work Together principles.

Our Enablers bring our Strategy to life 
and empower our people to succeed. 
Our Organisational Model is devolved to 
Corporate Functions and Assets whose leader’s 
accountabilities are outlined in our Global 
Process Standards and Specifications. The 
devolved organisation is connected through 
risk management and our Global Performance 
Standards set the minimum requirements for 
managing material threats. We are proud of 
our culture and see this as our most significant 
enabler for success.

Our Work is done by our Corporate Functions 
and Assets. It is prioritised using Risks in the 
context of both threats and opportunities. 
We are innovative in the development of our 
Business Plans and we use Value Creation 
to ensure we invest responsibly. As a Lean 
organisation we know when Partnering makes 
sense and we ensure the Capability of our 
people, processes and technologies allows  
us to deliver. We regularly set and track our 
Goals aligned to our effective planning.

Our Performance gives us the drive to continue 
to grow. We measure our Compliance to ensure 
we are doing what we say we will do. Our 
internal and external Reporting is data driven, 
and outcome focussed with the right people 
having the right information at the right time. 
We act with integrity and our Engagement 
with our stakeholders ensures we continue to 
deliver Value Creation. Our Assurance processes 
are there to make sure The OZWay is always 
followed and continuously improved.

Value Creation for Employees, Communities, 
Governments, Suppliers and Shareholders is core 
to who we are as a Company. We are collectively 
the people who make up OZ Minerals and How 
We Work Together will ensure we are Going 
Beyond What’s Possible to Make Lives Better.

OPERATING REVIEW

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 fifth successive year. 
Prominent Hill generated $440.3 million in 
free cashflow which helps us to develop our 
asset base and realise our growth aspirations. 
Prominent Hill’s mine life was extended to 2031 
with a 7% increase in Proved underground  
Ore Reserves(a). Mine expansion options are  
also being reviewed to assess opportunities  
to further extend the mine’s life. 

Highlights for 2019
 / Continued to ramp up underground mine 

production to 4.0Mt, with plant feed being 
supplemented with existing surface copper  
and gold stockpiled ores. 

 / Successful gold ore processing trials  

are expected to result in gold recovery  
rates increasing to approximately 77%  
from 71% for the 2020 calendar year(b).

 /

Improved our workforce diversity with  
an increase in Aboriginal participation. 

 / Successfully completion of a scheduled  
site evacuation for four days when the 
Department of Defence conducted testing  
in the Woomera Prohibited Area. 

 / A new 270 km transmission line currently 

being built as a part of OZ Minerals'  
South Australian power strategy, to meet 
operational requirements and enable our 
growth strategy for the region, and final  
tie-in is scheduled for 2020.

 / Completed phase one of the underground 
expansion study diamond drilling campaign 
and successfully progressed to phase two  
with 9.4 km of drilling. 

 / Completed a review of the site’s Critical  
Risk Management safety framework. 

 / Shaft haulage identified as the preferred 
method to handle potential production 
expansion scenarios in the Malu underground 
materials handling study. This work will now  
be refined as part of the expansion study. 

 / Construction of the Malu Paste Plant began 
and structural, mechanical and piping (SMP) 
package completed.

 / Over 1,000 competitors entered the Explorer 
Challenge competition and drilling began on 
identified targets near Prominent Hill mine.  
Seven holes were drilled in Q4 2019. More 
targets in these and other exploration areas  
are scoped to be drilled in 2020.

Safe and reliable operations
An expansion study to increase production 
post 2023 and extend the life at Prominent Hill 
is underway. The study builds on initial work 
conducted in early 2018, which supported 
further drilling and a materials handling study to 
test critical assumptions, including our geological 
interpretation of the area below the current 
Malu Life Of Mine area. 

Results from phase one of the expansion study 
diamond drilling (9.4 km) were encouraging and 
supported a second phase of drilling which will 
continue throughout 2020. These results, along 
with data from our materials handling study, 
will be incorporated into the broader expansion 
study and will be used to confirm the overall best 
value option as the basis for mine expansion and 
life extension. 

This study will continue throughout 2020,  
as we continue to define the resource and 
evaluate the various expansion cases. 

A key aspect of the expansion study will be 
to consider equipment powered by diesel 
alternatives and the opportunities enabled by 
automation to improve productivity and health 
and safety outcomes. A clear view on the 
potential underground expansion is expected  
in late 2020.

The processing of the regular grade gold 
stockpiles has been brought forward to the 
start of 2020 in place of the low grade copper 
stockpile after our gold ore processing trial this 
year demonstrated improved gold recovery.  
Data from the gold ore processing trial has  
also been used to develop metallurgical models 
that are now included in the 2020 business 
planning cycle.

We successfully completed a scheduled plant 
shutdown and site evacuation for four days 
when the Department of Defence conducted 
testing on the Woomera Prohibited Area. The 
closure enabled us to test our flexible work 
approach and gave us the opportunity to trial 
a temporary remote operating centre from our 
Adelaide office, which proved very successful.  
As a result, it will become a more permanent 
facility going forward.

The total recordable injury frequency rate  
for Prominent Hill in 2019 was 8.45, which  
was higher than the previous year. This was 
due to an increase in the number of recordable 
injuries of low severity resulting from more 
project work on site. 

Prominent Hill 
produced 102,479 
tonnes of copper and 
122,703 ounces of 
gold in 2019 at a 
lowest quartile C1 
cost of 55.8 cents  
per pound.

OZ MINERALSExplorer Challenge 
The Explorer Challenge brought together more 
than 1,000 active competitors from 64 different 
countries over three months, all competing 
for a million dollar prize pool. Entrants were 
challenged to turn previously unreleased 
Prominent Hill data into new knowledge to help 
us find new and innovative ways to interrogate 
the data we collect and identify new targets to 
test with drilling programs. 

The competition brought together a diverse 
range of participants from inside and outside 
the extraction industries, who helped us gain 
different perspectives on our multi-layered  
data sets. 

The winning entry from Team Guru employed 
interpretable machine learning models for 
mineral exploration using geochemistry, 
geophysics and surface geology. 

Six targets were identified in the competition

Working with our community

The Prominent Hill team and the 
Antakirinja Matu-Yankunytjatjara 
people, through their business entity 
AMY Nominees, were jointly nominated 
in the 2019 Aboriginal Enterprises in 
Mining Energy and Exploration (AEMEE) 
Awards as a finalist for the Resource 
Sector Collaboration Award. This 
nomination recognises OZ Minerals’ 
commitment to improving business 
outcomes for Traditional Owners and 
working together for shared success.

During the year, we increased 
engagement at the Coober Pedy Area 
School, with a school excursion held at 
the mine site and an exciting new VET 
pathways program being designed in 
collaboration with Career Employment 
Group, Port Augusta Secondary 
School and the Antakirinja Matu-
Yankunytjatjara people.

We also evolved our relationship with 
local pastoralists. Informal sessions were 
hosted at the site in training and lunch-
and-learn seminars, and a Christmas in 
July event was attended by the Chief 
Executive Officer and Site Management 
Team. These activities along with a 
broad range of site employees attending 
station events saw vital relationships 
further enriched during the year.

Carrapateena

Carrapateena is an iron-oxide–copper–gold 
(IOCG) underground mine located in the highly 
prospective Gawler Craton in South Australia 
approximately 250 km from the Prominent Hill 
mine. Carrapateena produced first concentrate 
in December 2019 following a three-year 
construction period and is targeting a 12 month 
ramp up period to achieve its full production 
rate of 4.25 Mtpa, provided the cave propagates 
as expected. It is an underground sub-level 
cave operation with an estimated mine life of 
20 years. A feasibility study is underway into 
the future expansion of the bottom half of the 
operation into a block cave. 

Highlights for 2019
 / First saleable concentrate produced in 

December 2019, with 295,000 tonnes of 
development ore stockpiled on the surface  
at the end of the year. 

 / Total development reached 21,922 metres 
(4,900 metres for the Tjati decline) with a 
vertical depth of 702 metres.

 / The site was connected to the grid power 
network by a dedicated transmission line.  
The minerals processing plant produced  
first saleable concentrate in December.

 / A seismic monitoring system was installed  

and commissioned.

 / The 550 person Tjungu accommodation  

village was completed. 

 / A 1,600 metres sealed aerodrome 

commissioned in 2018 continued safe 
operation with a 98% on time flight 
performance. 

 / The operation’s workforce was recruited on 

time and under budget with 87% of recruited 
employees residing in South Australia. 

 / Tailings storage facility completed on schedule.

 / Plans are underway to expand the 
Carrapateena operations, with the 
Carrapateena block cave expansion study in 
pre-feasibility stage and the Carrapateena life 
of province plan in scoping study, furthering 
our provincial approach to mine development. 

 / Stage 1 of the northern well field was 

commissioned and is supplying water to site.

 / All ventilation fans were commissioned.

 /

Improvements were made to the southern 
access road in consultation with stakeholders 
to accommodate oversize and over mass 
vehicles entering site. 

 / Over 600 people have worked on site, with 
20% linked to the Upper Spencer Gulf. 

Safety focus
Throughout the year, 24 new Carrapateena 
Emergency Response Team (ERT) members 
completed specialist training in Underground 
Emergency Response. The ‘Bring It Home’ 
safety initiative was launched to further embed 
behavioural safety practices as the site was 
completing surface construction activity and 
continuing to stockpile underground ore.

The total recordable injury frequency rate  
for 2019 has reduced to 7.24 down from  
7.52 during 2018. An increase in lower 
consequence injuries was also recorded at 
Carrapateena and a review of current site task-
based behaviour programs has commenced. 
During the year, there was a fatal incident 
involving an ElectraNet sub-contractor, who was 
a helicopter pilot working on stringing the power 
line to the Carrapateena project. The incident 
had a profound effect on the whole Company, 
especially the Carrapateena team.

OPERATING REVIEW

Working with our community – Carrapateena

A focus of Carrapateena has been stakeholder engagement and involvement. Throughout 2019,  
we continued to create value for our stakeholders by: 
 / ensuring a ‘South Australia first’ recruitment strategy – over 80% of our Operations’  

workforce live in South Australia with numerous employees relocating to South Australia  
to take up employment at Carrapateena; 20% of the Operations workforce reside in the  
Upper Spencer Gulf

 / hosting local leaders, including the Mayors and CEOs of the three Upper Spencer Gulf cities  
for a site visit to observe construction progress and discuss opportunities for further regional 
value creation

 / working closely with our pastoral stakeholders seeking innovative ways to create value,  

such as the supply of treated water for stock watering in a period of drought 

 / supporting our Traditional Owners, the Kokatha People, to seek employment and business 

opportunities with the operation

 / directly engaging local pastoralist and Kokatha businesses, including in dust suppression,  
road maintenance, laboratory courier services, fence construction and other construction  
related activities

 / hosting a Kokatha specific processing training program in partnership with TafeSA,  

the Kokatha Aboriginal Corporation and other groups

 / supporting entry level employment programs with our site services partner, ISS
 / supporting various local community events and initiatives including the first multi-trade  

program with other major employers in the region, hosted in Port Pirie

 / seeking apprentices from the Upper Spencer Gulf
 / engaging multiple local suppliers in contracting opportunities both directly and through  

our contracting partners, with a total value of more than $7.2 million awarded. 

The Carrapateena team participated in the Port Pirie Jobs Fair and ran the first OZ Minerals  
Career Hub, an innovative way of streamlining the interview and recruitment process to make  
it more accessible for regional applicants. 

The team also finalised a cross-asset graduate program for its 2020 intake, with participants  
now able to gain experience at Carrapateena and Prominent Hill. The Regional Training  
Community of Practice also met for the first time with local registered training organisations,  
further building positive relationships with local Upper Spencer Gulf businesses.

Our focus in 2020 is to: 
 / advance psychologically safe work culture

 / safely ramp up to full production target  

of 4.25Mtpa by end 2020

 / progress the Carrapateena expansion  
study, including fundamental caving  
and infrastructure studies

 /

investigate additional technological 
opportunities such as mine to mill digitisation

 / trial a 250 kW hybrid energy solution facility 
to develop renewable energy solutions and 
demand management opportunities. This is 
part of the Energy and Mining Collaboration, 
an initiative by OZ Minerals in collaboration 
with Adelaide University, CSIRO, the 
Department of Energy and Mining, the Rocky 
Mountain Institute, SunSHIFT and the Tonsley 
Innovation Precinct

(b) Further details are contained in the 

announcement entitled “Carrapateena  
Block Cave Expansion has potential to 
optimise value and further unlock the 
province” which was released to the market 
on 6 March 2019 and is available to view  
at ozminerals.com/media/asx.

 / continue to explore province expansion and 
future life extension options through drilling  
at Khamsin, Fremantle Doctor, the Saddle  
and Carrapateena

 / optimise our workforce composition with an 
emphasis on diversity and workforce flexibility

 / continue to focus on providing local supply 

opportunities

 / maintain stakeholder relationships and 

continuously consider stakeholder value 
creation initiatives.

Carrapateena mine and  
province expansion
The Block Cave Expansion Scoping Study 
was completed in 2019 and determined that 
replacing the lower half of the sub-level cave 
with a block cave and expanding the annual 
throughput rate from 4.25Mtpa to 10–12Mtpa 
from 2026 could create significantly more value 
than a sub-level cave development alone. 

The study outlined the potential to increase 
average life of mine copper production from 
65,000 tpa to ~105,000–125,000 tpa from 2026 
and reduce life of mine all-in sustaining costs.(b) 

The project has now moved to the pre-feasibility 
stage, which is expected to be completed by 
mid-2020. Diamond drilling has begun to help 
improve our understanding of the geotechnical 
aspects and resources of the sub-level cave and 
potential block cave areas to support ongoing 
expansion studies.

A drilling program has also commenced to help 
us understand the full potential of the wider 
Carrapateena province, including drilling sites  
at Khamsin, Fremantle Doctor, the Saddle and 
Carrapateena itself. 

The drill program at the Punt Hill joint venture 
with Red Metal Limited was completed during 
the year with six holes drilled. We exited this 
earn-in agreement in Q4 2019.

OZ Minerals has also entered into a new 
exploration earn-in agreement to explore for 
IOCG style resources with Investigator Resources 
Limited (ASX:IVR) at the Maslins prospect, 
located on the Stuart Shelf approximately  
55 km south of Carrapateena. Field work has 
commenced and is focused on the Maslins 
geophysical anomaly, involving infill gravity 
and magneto-telluric (MT) surveys. Detailed 
interpretation and modelling of the data  
is underway, and drilling is expected to  
commence in Q1 2020.

Musgrave

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

The Musgrave province is a highly prospective 
region spanning Western Australia and South 
Australia. The West Musgrave project is a joint 
venture with Cassini Resources (ASX:CZI), with 
the pre-feasibility study recently completed  
along with the announcement of a maiden  
Ore Reserve estimate. Full details are available  
at ozminerals.com/media/asx.

West Musgrave overview

Location: Western Australia  
near the South Australia and 
Northern Territory border

Earn-in agreement: Cassini  
Resources 30% ownership;  
OZ Minerals 70% ownership

Deposit: Copper and Nickel

Status: Pre-feasibility study stage

Province exploration program:  
One Tree Hill prospect and the 
Succoth deposit

West Musgrave project
The West Musgrave project is located in  
Western Australia, near the South Australia  
and Northern Territory borders. West  
Musgrave contains three known deposits – 
Nebo, Babel and Succoth – as well as the  
One Tree Hill prospect. The Nebo and Babel 
copper-nickel deposits are the current focus  
of drilling and studies.

We have now reached 70% ownership of  
the West Musgrave project and our confidence 
in the Nebo-Babel deposits has improved as  
infill drilling has enabled the conversion of 
Inferred Resources to the higher confidence 
Indicated category.

The pre-feasibility study timeline was extended  
in 2019 so we could complete a detailed 
evaluation of additional value-add opportunities. 
The most significant, the use of a dry vertical 
roller mill to reduce power consumption, 
has been complemented by reducing the 
onsite workforce through remote operations, 
optimising power supply and demand, and  
using alternative processing technologies.

In parallel with the pre-feasibility study,  
OZ Minerals has developed stronger  
relationships with the local community and 
progressed baseline environmental studies 
with a view to submitting regulatory approvals 
documentation in 2020. Discussions with the 
Traditional Owners are ongoing, with a view  
to developing a Mining Access agreement.

2019 highlights
 / Ran a successful collaboration Hub with  
150 members of the local community in 
Jameson, receiving feedback on the concerns 
and aspirations of the Traditional Owners.

 / Collaboration Hub ran with 10 Western 

Australian Government departments that 
identified opportunities to work together  
to add value.

 / Completed a mining study that examined 
a wide range of scenarios to arrive at an 
optimised project configuration. 

 / Metallurgical testing confirmed recovery  

and concentrate quality targets for all types  
of ore present in the deposit.

 / Base case power reduced from 65 MW to 

55 MW by developing a new flowsheet and 
adopting the vertical roller mill technology  
over a traditional Semi-Autogenous-Grinding 
Mill and Ball Mill circuit. 

 / Established the feasibility of powering the 
project using a low emission diesel–solar– 
wind-battery solution with 70–80%  
renewable penetration. 

 / Confirmed that an off-site, integrated 

operations centre will reduce the workforce 
required on site and provide more flexible 
working arrangements for our people.

 / Progressed planning for the mine access 
agreement and regulatory approvals.

 / Cassini Resources completed an aeromagnetic 
survey (3,978 line km) at the One Tree Hill 
prospect and a further four holes were  
drilled (1,486 metres). 

 / Completed infill drilling (two holes,  

852.9 metres) on one Succoth prospect section 
to confirm our geological interpretation. 

Working with the community 

The team worked with the local community to  
co-design elements of the West Musgrave project  
and maximise community value where possible.  
More than 150 community members attended a 
Community Consultation Hub in Jameson to learn  
more about the project and discuss their aspirations. 

A Western Australian Government Hub process was 
created to introduce OZ Minerals, Cassini Resources 
and the project to different branches of government. 
Attendees from more than ten departments joined us  
to explore opportunities to work together and add value 
to the project, particularly from a community point of 
view. The project team also volunteered at the Desert 
Dust Up event in Warburton with school children from  
the local Ngaanyatjarraku Shire.

Our focus for 2020 is to: 
 / commence development of a mine access 
agreement with the Traditional Owners 

 / Planned infill drilling at Nebo and Babel 

completed and rigs demobilised from site.

 / submit approvals documentation to  
the Western Australian regulator.

OPERATING REVIEW

Carajás

The Carajás in Brazil is one of the world’s 
premier IOCG mineral provinces and is host to 
the world’s largest iron ore mine and a number 
of sizeable copper–gold mines. OZ Minerals has 
the operating open pit mine at Antas, the Pedra 
Branca underground project under construction, 
as well as the high grade copper–gold 
exploration projects Pantera and Clovis. 

OZ Minerals has also entered into earn-in 
agreements with Vale S.A. for options to 
purchase two nearby exploration projects; 
Santa Lucia, an advanced exploration project 
approximately 40 km trucking distance from 
Antas, and the less advanced but highly 
prospective Circular North. 

We are implementing a staged, low risk and 
capital conservative Hub strategy in the province 
that will see copper processing facilities serving 
multiple small and mid-sized mines in the  
region. The first Carajás Hub will be the 
Antas facility which will process ore trucked 
from the ~1Mtpa Pedra Branca underground 
mine, located 75 km from the Antas plant. 
Construction began on the Pedra Branca mine 
in December 2019 with first development ore 
expected to be reached in mid-2020.

The Antas mine produced 6,810 tonnes of 
copper and 6,171 ounces of gold in 2019. 

Mining studies have been developed with  
a focus on pit wall steepening to extend  
the life of the mine until mid-2021. 

Antas Overview

 / Carajás TRIFR for 2019 was 1.34 with  

OZ Minerals’ reporting governance to be 
adopted in 2020. 

 / A high calibre advisory board was established 
in Brazil complementing the strategic depth 
and capability of the local management team.

 / During the year, an updated risk assessment 
and incident investigation using the Incident 
Cause Analysis Method (ICAM) was introduced 
across the Carajás, with assistance from other 
OZ Minerals operations. This was combined 
with the roll out of OZ Minerals’ governance 
standards.

 / Resource extension drilling was completed 

focusing in and below the current Antas North 
open pit (5,566 metres), resource infill drilling 
(1,115 metres) at the satellite Azevedo open 
pit and limited near mine exploration adjacent 
to the current open pit (1,244 metres).

 / Utilisation of a lower cost wall steepening 

approach to access deeper ore. This 
contributed to a site all-in sustaining  
cost performance of US$2.95 c/lb.

 / Further underground drilling was progressed, 
with several drill holes intersecting copper 
bearing structures (3,200 metres) at the Clovis 
prospect. An exploration target of 2.0-4.0 
million tonnes at a grade of 3.1-5.0% copper 
was determined. The potential quantity and 
grade of the Exploration Target is conceptual  
in nature.(a)

 / The Pedra Branca Feasibility Study Update 
Report and preliminary mine optimisation 
studies were completed, to identify the best 
value proposition for mine scale and design.  

Construction on the Pedra Branca decline 
began in December 2019 and first

OPERATING REVIEW

Gurupi

The Gurupi province is in the state of Maranhão 
in northern Brazil, between the cities of Belém 
and São Luis. OZ Minerals' CentroGold project 
sits in this province and is considered to be one 
of the largest undeveloped gold projects in 
Brazil, with three main deposits: Blanket,  
Contact and Chega Tudo. 

The larger CentroGold area is considered to  
host exciting exploration potential. Interpretation 
of a vast database of historical information, 
including soil geochemistry and drilling also 
suggests potential associated with the proximal 
Chega Tudo deposit and eight other known 
targets including Mandiocal, Sequeiro and 
Jibóia. The acquisition of the Jibóia exploration 
tenements to the north of CentroGold has 
expanded the total land package held to  
~2,300 km2 along 85 km of strike length,  
with the CentroGold project now comprising  
less than 3% of this land.

Gurupi’s potential has strengthened with the 
CentroGold pre-feasibility study demonstrating a 
minimum 10-year operation could be developed 
for low capital investment with industry bottom 
half operating costs. 

CentroGold
Our pre-feasibility study estimates that 
CentroGold will have a life of mine average  
gold production of 100,000–120,000 oz per 
annum, with 190,000–210,000 oz per annum 
in the first two years(b). Construction costs are 
estimated to be approximately US$155 million 
for a project NPV of US$203.2 million, and a life 
of mine all-in sustaining cost of US$640/ oz. 

 / CentroGold is expected to become a Gurupi 
processing hub, servicing nearby deposits  
such as Chega Tudo, eleven and a half 
kilometres to the west. This year we have 
focused on permitting and village relocation 
planning, which involves face to face 
interviews for a relocation plan applying 
international standards. Aerial surveys were 
completed for the Cipoeiro township and have 
been expanded to the wider mining lease. 

lifting the injunction, which was granted in 
2013 by a Federal Court judge against the 
then tenement holder citing irregularities in  
the grant of the environmental licence.

2019 highlights 
 / We completed the pre-feasibility study, which 

included only the Blanket and Contact deposits 
and issued the maiden Ore Reserve estimate. 
The potential future addition of the nearby 
Chega Tudo deposit, following further studies, 
may also add to the project production profile.  

 / We progressed the legal process of lifting the 
injunction while continuing village relocation 
assessments and planning.

 / We developed a low risk, modest capital  

hub concept for the Gurupi province.

 / We undertook limited high value resource  
infill drilling at the Blanket (4,646.9 metres) 
and Contact (6,334.9 metres) deposits. 

 / We began regional exploration with drilling 
at the Sequeiro and Pica Pau targets in the 
southern end of the Gurupi landholding,  
with 809 metres of drilling completed at  
the Pica Pau target and 1,054 metres of  
drilling completed at the Sequeiro target. 

 / We purchased the Jibóia tenement which 
consolidates the Gurupi greenstone belt, 
bringing the province total land package  
to 2,300 km2 along 85 km of strike length.

 / Construction of a new base camp at  

the Jibóia project continued along with 
geological mapping/sampling.  

 / Construction of a new metal core shed  

for sample storage at Chega Tudo.

Our focus in 2020 is to: 
 / progress removal of the injunction

 / continue the approvals process and local 

community engagement programs 

 / update the Mineral Resource,  

Ore Reserve and pre-feasibility study

 / progress to a feasibility study  

(contingent on injunction removal)

 / The Feasibility Study and further regional 

 / continue regional exploration

exploration are anticipated to begin when 
the injunction over the CentroGold project 
is removed. A final assessment report by 
the local INCRA (the Colonization and Rural 
Reform Institute) has been prepared stating 
their support. The report is awaiting evaluation 
from INCRA in Brasilia. The ANM (National 
Mining Agency) has also issued a favourable 
report that supports the planned future mining 
activity at CentroGold. Both are important 
steps in gathering institutional support for 

 / validate historic exploration drilling  

over CentroGold and Jibóia

 / commence an expanded drilling  

program over both the CentroGold  
project and ranked exploration targets 
(contingent on injunction removal)

 / commence an airborne survey and

Exploration and growth

Growth through exploration is a central part of our strategy to 
create value. We have built a well-developed growth pipeline 
with multiple projects at different stages of maturity. This allows 
us to allocate resources to the most value-accretive activities and 
gives us more options when deciding which projects to progress. 
We rigorously pursue our pipeline of opportunities and if at any 
time we determine that a project does not have the potential to 
generate substantial value, we cease expenditure and withdraw 
from the arrangement in line with our obligation and intent to 
invest responsibly.

OZ Minerals has several exploration earn-in agreements in place with highly regarded explorers who 
provide us with expertise in specific geologies or locations. Our partners, in turn, access capital to 
undertake drilling programs. OZ Minerals typically works with its partners to oversee projects while 
they manage on-the-ground-activities. 

Our exploration growth pipeline expanded this year with new earn-in agreements in the 
Carrapateena province (Investigator Resources Limited) and Sweden (Mineral Prospektering i Sverige), 
a new multi-site exploration greenfield discovery alliance (Red Metal Limited) targeting base metals 
mineralisation in WA and QLD, and a new joint venture in QLD (Minotaur Exploration). Our earn-in 
agreement with Woomera Mining Ltd was terminated, due to licence renewal issues. No field work 
was undertaken on our Oaxaca projects in Mexico this year while permitting was pursued, and the 
agreement was subsequently exited.

Exploration portfolio

Multi-site exploration alliance  
with Red Metal Limited
In January 2019 OZ Minerals entered into an 
exploration alliance with Red Metal Limited, 
which significantly increased its exploration 
footprint in Australia. The alliance gives  
OZ Minerals a two-year option to fund a series 
of mutually agreed, proof-of-concept work 
programs on six of Red Metal’s early-stage 
projects, which include:

 / Yarrie for copper–gold in WA

 / Nullarbor for copper–gold and  

copper–nickel in WA

 / Gulf for copper–gold in QLD

 / Lawn Hill for zinc–lead–silver in QLD

 / Three Ways for zinc–lead–silver in QLD

 / Mount Skipper for zinc–lead–silver– 

copper in QLD

Since January, cultural heritage surveys and 
local level agreements have been completed at 
Mt Skipper and drilling has begun (single hole, 
950.8 metres). No significant mineralisation 
was intercepted and follow up geophysical 
work (downhole and ground Electro Magnetic 
survey work) has been completed. Cultural 
heritage surveys and local level agreements 
were completed for the Nullarbor project and 
an infill gravity survey has identified several 
targets where drilling commenced in Q4 2019. 
We finalised an extensive magneto-telluric (MT) 
survey at the Three Ways project and drilling is 
expected to begin at that prospect in Q2 2020.

OPERATING REVIEW

Maslins project, Investigator  
Resources Limited
We entered into a new exploration earn-
in agreement to explore for IOCG with 
Investigator Resources Limited (ASX:IVR) at the 
Maslins prospect, located on the Stuart Shelf 
approximately 55 km south of Carrapateena. 
Investigator Resources is an ASX-listed Australian 
mineral explorer with extensive exploration 
experience in the Gawler Craton of South 
Australia. Infill gravity and MT surveys were 
conducted and detailed interpretation and 
modelling is complete with associated drilling 
anticipated in Q1 2020.

Eloise joint venture with  
Minotaur Exploration
OZ Minerals attained a 70% beneficial interest 
in the Eloise joint venture after reaching an 
investment of $10 million over three years. 
The Cloncurry district contains strong mineral 
endowment in a variety of commodities. A  
major drill program (80 holes, 21,000 metres)  
was undertaken in 2019 to delineate the  
central portion of the mineralisation at Jericho 
where the best grades and thicknesses have 
been intercepted.

Jericho joint venture with  
Minotaur Exploration
In a refinement of our relationship with  
Minotaur Exploration in the Cloncurry area, 
Jericho was excised from the Eloise joint venture 
area to create a separate joint venture around 
the Jericho discovery. OZ Minerals agreed to  
loan carry Minotaur Exploration’s funding  
share of Jericho from 1 April 2019 in return 
for an 80% beneficial interest in the project. 
58 holes have been drilled with the aim of 
increasing confidence in the thickness and  
grade distribution of the J1 and J2 lodes. 

We also significantly increased our footprint in 
the Cloncurry District of north west Queensland 
through formation of the Cloncurry Regional 
Alliance with Minotaur Exploration.

Lannavaara with Mineral  
Prospektering i Sverige AB
OZ Minerals has an agreement with private 
explorer Mineral Prospektering i Sverige 
(MPS) to explore for IOCG mineralisation in 
the Norrbotten district of northern Sweden. 

OZ Minerals can earn 75% of the project by 
spending US$10 million over 66 months and 
has the right to purchase a further 25% equity. 
Ground based EM and magnetic geophysical 
surveys were completed at the Lannavaara 
project in northern Sweden in 2019 along 
with drilling (8 holes, 1,862.9 metres). Results 
confirmed the presence of a low grade, 
structurally-controlled pyrrhotite/chalcopyrite 
sulphide system as well as lesser skarn 
mineralisation. Further ground-based geophysical 
surveys and drilling is planned for 2020.

Painirova project with Mineral 
Prospektering i Sverige AB 
We expanded our partnership with Mineral 
Prospektering i Sverige AB by signing a new 
earn-in agreement on the Painirova project in 
northern Sweden. Painirova is located between 
the Mertainen iron-oxide–apatite deposit and 
the active Leveäniemi mine at Svappavaara in 
Sweden’s most prolific mining belt. We made 
an initial commitment to spend US$500,000 on 
exploration after which further budget approval 
can be sought to continue exploration activities. 

An airborne EM and magnetic survey of  
1,668 line kilometres was flown, with 
preliminary data highlighting several areas  
for follow up ground works and drilling.

Paraiso with private Peruvian company 
Inversiones Mineras La Chalina S.A.C.
In December 2018, OZ Minerals entered into  
an earn-in agreement with Inversiones Mineras 
La Chalina S.A.C. to explore for IOCG deposits  
in the Arequipa district of southern coastal  
Peru. We committed to spend US$500,000  
on exploration in the first 12 months, after 
which we can elect to proceed with the project. 
If we progress, OZ Minerals can earn 100%  
of the project by spending US$11.5 million  
over five years.

Field work began during the year, with a 
successful community engagement process 
enabling a three-month geological mapping 
and sampling program. The program identified 
a number of geochemical anomalies which 
required further on-ground assessment and 
initial geophysical surveys. We have initiated  
the drill permitting process, which is anticipated 
to take six to nine months. Drilling is expected  
to begin in H2 2020.

OZ MINERALS21

Governance Framework 

Our governance framework has been 
designed to enable lean business 
processes that drive clear accountabilities 
and create room for innovation and 
is explained through The OZWay. The 
OZWay is a simple model that includes 
our purpose, our desire to be a modern 
mining company and strategy to create 
value for our five stakeholder pillars.

Our Context 

As a modern mining company, with a focus  
on global copper, we are agile to the changes  
in our macro environment and we listen and  
act on our stakeholder expectations. All 
corporate and asset documents comply with  
the laws and regulations of the jurisdiction in 
which each asset operates.

Our Choices

We have a global devolved operating model, 
ensuring our assets are autonomous and 
accountable. We focus on what matters, and  
set processes that create value, embrace the 
global devolved model and provide clarity for 
new assets, partners, suppliers and employees 
coming into OZ Minerals.

Our How We Work Together (HWWT) Principles 
and underpinning behaviours are embedded 
in our everyday activities, core systems and 
processes and enable growth, innovation  
and collaboration. The HWWT Principles drive 
transparency and fair dealing and propagate 
a culture of performance and devolved 
accountability – this allows us to deliver on  
our Strategy.

Our Code of Conduct applies standards for 
appropriate ethical and professional behaviour.  
It provides guidelines to our employees, 
directors, contractors and partners as to our 
expectations regarding issues such as conflict 
of interest, gifts, entertainment and gratuities, 
anti-bribery and corruption, equal opportunity 
and speaking up.

OZ Minerals is determined to create shared  
value for all our stakeholders, which is at the 
heart of our Strategy. We have five Value 
Creation Policies which are designed to provide  
a clear representation of our intent and make 
our intent transparent to our stakeholders to 
enable them to hold us to account. Our Value 
Creation Policies, along with our Securities 
Trading, Continuous Disclosure, Anti-Bribery  
& Corruption, Inclusion & Diversity and Speak  
Up materials are publicly available.

Our Enablers

Underpinning the Policies are Performance 
Standards that enable us to effectively manage 
the material threats and opportunities that are 
common across OZ Minerals. The Performance 
Standards are grouped into four key areas - 
safety, environment, health and wellbeing, and 
social. They set out the minimum mandatory 
control requirements and accountabilities to 
manage risks, comply with the law, design 
operating systems with devolved accountability 
and provide criteria for measuring value  
creation performance.

The Performance Standards are 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 working 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.

Our global Process Standards and associated 
Specifications enable us to work effectively 
within our devolved model by describing the 
accountabilities and authorities of the Board, 
CEO, Executive Leads and Leads of the Corporate 
Functions and Assets relating to key business 
processes and management activities. They are 
the activities that we undertake that are unique 
to us, and the Process Standards are used by our 
employees, functions and assets. They define 
the inputs and outputs required, the processes 
people must follow and the delegations that 
they can work within.

Our Performance

Internal and external audits
Risk management, audit and assurance  
underpin the Process and Performance  
Standards as critical elements of our Audit  
and Assurance Governance Framework. 

We conduct regular audits to systematically 
and objectively verify that we conform with 
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 assessed risk profile.

Environmental regulation
OZ Minerals and its activities in Australia, Brazil and other international locations are subject to strict 
environmental regulations. OZ Minerals’ Prominent Hill, Carrapateena and Carajás operations, along 
with its exploration and concentrate shipping activities, operate under various licences and permits 
under state, federal and territory laws in Australia, Brazil and other overseas jurisdictions.

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 its energy and emissions report to the Clean Energy  
Regulator in accordance with the National Greenhouse and Energy Reporting Act 2007 (NGER Act). 
KPMG provided limited assurance over OZ Minerals’ energy and emissions report. 

KPMG has also provided limited assurance over selected metrics and disclosures in the OZ Minerals 
2019 Annual and Sustainability Report against the requirements of the Global Reporting Initiative 
Standards. KPMG’s assurance report is available on page 103.

The Company has not incurred any significant liabilities under any environmental legislation during 
the financial year.

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, current and former officers, the former General Counsel 
(Special Projects), the former Group Treasurers 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 any 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.

DIRECTORS' REPORT

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 112 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 
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; or

 / 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 18 February 2020. The record date for entitlement to this dividend is 
12 March 2020. The financial impact of the dividend, amounting to $48.6 million, has not been 
recognised in the Consolidated Financial Statements for the year ended 31 December 2019 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.

to OZ Minerals, for example, information that is commercially sensitive, confidential or could give a 
third party a commercial advantage, has not been included. Other than the information set out in  
the Operating Review and the Financial Review, information about other likely developments in  
OZ Minerals’ operations and the expected results of these operations in future financial years has  
not be included.

DIRECTORS' REPORT

OZ MINERALS33

Financial review

OZ Minerals’ net profit after tax (NPAT) for the year was $163.9 million compared to $222.4 million 
for 2018, principally due to lower copper sales as Prominent Hill transitions from its higher copper 
grade open pit stockpiles and higher exploration and corporate development expenditure. Base 
metal markets remained volatile throughout the year as trade tensions and geopolitical uncertainty 
dominated over robust fundamentals, albeit a weaker Australian dollar improved comparative A$ 
copper pricing. A counter response in precious metal markets supported higher gold revenues,  
noting that 57% of gold sales were delivered against previously established price hedges reducing 
net revenue by $23.9 million. 

Underlying NPAT for the period was $163.9 million compared to $228.3 million in the comparative 
period in which transaction costs for the Avanco acquisition were treated as non-underlying.

Prominent Hill once again delivered a reliable production and cash cost performance, as underground 
mining rates stepped up and higher-grade underground ore was supplemented with open pit 
ore stockpiles. Exploration and evaluation expenditure increased as OZ Minerals’ growth pipeline 
further developed, with concurrent expansion studies and exploratory drilling in the Prominent Hill, 
Carrapateena, Carajás, Gurupi and Musgrave provinces. OZ Minerals’ margin for earnings before 
interest, tax, depreciation and amortisation (EBITDA) remained robust at 42% (2018: 48%) while 
continuing to invest in exploration and evaluation activities. 

OZ Minerals’ closing cash balance of $134.0 million decreased by $371.1 million during the year with 
strong operating cashflows utilised for further significant investment at Carrapateena, expenditure on 
exploration and evaluation activities, and tax payments and dividends to shareholders.

DIRECTORS' REPORT

Revenue

Gross revenue of $1,173.9 million was lower than the previous year by $17.2 million with lower 
copper and gold sales partially offset by higher Australian dollar realised copper and gold prices.  
The realised $A copper price was 2% lower than in the comparative period while the net $A gold 
price was 12% higher. Revenue includes $23.9 million in realised losses on gold hedges.

Realisation costs

Treatment charges and refining costs (TCRCs) were $7.2 million lower as a result of improved trading 
terms and lower refining charges in the global market.

Royalty expense increased by $1.4 million due to the non-deductibility of hedging losses in calculating 
royalty was payable.

Production costs

Absolute production costs in 2019 were higher than the previous year by $14.1 million, with the 
inclusion of the Carajás operations for the full year (only from the second half of 2018 in the 
previous year), an increased proportion of underground ore, higher transport and site administration 
expenditure, partially offset by the net realisable value adjustment recognised during the year. 

Exploration and corporate development expenditure

Exploration and corporate development expenditure of $93.9 million was incurred during the year 
to progress the Carrapateena expansion study, drilling and development studies in the Gurupi and 
Carajás provinces, and other exploration earn-in arrangements in the growth pipeline:

 / Carrapateena expansion $18.6 million

 / Brazil study costs and exploration $37.6 million

 / other exploration and development expenditure $37.7 million.

Other expenditure

Corporate, general and administration, and other costs of $50.2 million increased by $21.2 million 
over the prior year with further organisation capability build, higher insurance costs from a rising 
premium market and restructuring in Brazil. The corporate, general and administration costs in 
the year included a full year amortisation charge of $6.5 million relating to intellectual property 
technology associated with the Concentrate Treatment Plant. 

The income tax expense of $64.7 million was $25.8 million lower than the previous year as a result  
of the lower profit and the benefit of restricted prior year tax losses recognised during the year.

Finance expense of $10.0 million was $4.9 million higher than the previous year following the 
implementation of AASB 16 Leases, which resulted in the recognition of finance charges in relation  
to lease liability provisions.

Operating cash flows

Operating cash flows of $510.6 million for the year were $61.0 million higher than in 2018. 
Customer receipts during the year were lower by $64.2 million due to the timing of concentrate 
sales. Payments to suppliers and employees were $492.7 million for the year, $57.5 million lower 
than in 2018 primarily due to the reclassification of certain payments to suppliers as financing 
cashflows under AASB 16 Leases. Payments for exploration and corporate development expenditure 
increased by $28.9 million reflecting the ongoing investment in the growth pipeline during the year. 
PAYG tax payments were $104.6 million lower than the previous year which included a finalisation 
payment for the Company’s tax liability from 2017, prior to the Company’s transition to a PAYG 
regime, and lower earnings before tax for the year.

Investing cash flows

Net investing cash flows of $763.9 million were attributable to development costs at Carrapateena, 
general property, plant, equipment and mine development at Prominent Hill and the Carajás, and 
study costs associated with the West Musgrave project:

 / capitalised Carrapateena project development costs $579.2 million

 / Prominent Hill mine development costs $56.6 million and growth costs of $45.9 million  

(principally related to the Malu Paste plant)

 / Brazil including capitalised exploration and evaluation costs $9.9 million 

 / sustaining and other capital expenditure including power transmission infrastructure $46.1 million

 / West Musgrave capitalised exploration and evaluation costs $26.2 million.

DIRECTORS' REPORT

Financing activities

Cash outflows relating to financing activities comprised $74.3 million in dividend payments to 
shareholders and $47.3 million in payments to suppliers now classified as lease payments following 
the application of AASB 16 Leases. 

Since the end of the year, the Board of Directors has resolved to pay a final dividend for the 2019 
financial year amounting to $48.6 million. This final dividend will be fully franked for Australian  
tax purposes.

Balance sheet

The total equity of the Company increased by $64.7 million to $2,979.9 million. The increase resulted 
mainly from the year’s NPAT of $163.9 million, partially offset by returns to shareholders in the form 
of dividends amounting to $74.3 million and a decline in the value of open gold derivative contracts 
of $28.1 million (net of tax). The movement in the net assets of the Company since 31 December 
2018 is provided below:

OZ MINERALS 
37

At the end of the year, the Company held a cash balance of $134.0 million and undrawn debt 
facilities of $300.0 million. The reduction in the cash balance was a result of operating cash flows 
being offset by ongoing investment in Carrapateena, Prominent Hill, West Musgrave, and Property 
Plant and Equipment (‘PP&E’), as well as the payment of dividends. Inventories of $537.6 million 
at the end of the year had reduced by $140.8 million since 1 January 2019 as a result of the 
consumption of open pit ore from stockpiles, with the associated cost recognised in the income 
statement within inventory adjustments.  As open pit ore stockpiles are consumed, the previous  
costs of mining this ore and the related capitalised depreciation (collectively comprising ‘open pit  
ore inventory’) will continue to be progressively amortised through the income statement.

Trade receivables increased due to the timing of shipments, with a final shipment for the year in late 
December 2019. PP&E and Exploration assets increased during the year mainly due to the ongoing 
capitalisation of underground development expenditure at Prominent Hill, capital expenditure at 
Carrapateena, capitalised West Musgrave exploration and study costs, and general sustaining capital 
expenditure, partially offset by depreciation. 

Lease assets and liabilities were recognised during the year as the consolidated entity adopted 
the new accounting standard AASB 16 Leases from 1 January 2019. The Standard requires the 
recognition of an asset and associated liability where the lease provides certain committed use rights 
over infrastructure and equipment within contracts.

DIRECTORS' REPORT

OZ Minerals Risk Management

OZ Minerals’ operating performance and 
financial results are subject to a wide 
range of risks and uncertainties including 
financial, political, social, operational and 
environmental factors that create both threats 
and opportunities. The consolidated entity 
manages and mitigates current and emerging 
risks to minimise adverse impacts and maximise 
beneficial outcomes. Our risk management 
framework emphasises risk-aware decision-
making to achieve OZ Minerals’ Strategy.

At the centre of OZ Minerals’ Strategy is Value 
Creation. Creating Value for stakeholders is  
an outcome of effective risk management.  
Our risk impact assessment table is centred 
around five stakeholder pillars and to align 
with our strategic focus, risks are assessed to 
determine the potential impact on each pillar.

Risk management accountability and oversight 
is a central part of the OZ Minerals governance 
framework. The Board, its sub-committees and 
the Executive leadership provide oversight and 
monitoring of risk management process and 
practice. Collectively, they are responsible for 
ensuring the Company maintains an effective 
risk management standard and internal control 
environment. 

The Board has an oversight responsibility and 
determines the overall risk appetite for the 
consolidated entity. OZ Minerals’ corporate 
governance structure and communication 
channels enable timely responses to current  
and emerging risks. 

Risk Management 
Oversight and Governance

Board: The Board reviews and monitors the 
material risks of the Company and its system 
of internal compliance and controls. The 
Board oversees the risk management process 
and approves the risk management standard, 
including the Company’s risk appetite. The Board 
regularly reviews and monitors the Company’s 
risk profile and management report risks 
through the Company’s monthly Risk Report. 
The report includes an overview of Company 
risks, a summary of key changes to the risk 
profile, critical control updates, and the actions 
implemented to reduce the level of uncertainty 
and improve the manageability of risks. The 
Board requires CEO and Executive leadership to 
implement a system of control for identifying, 
assessing, managing and reporting risks in line 
with the risk management framework.

Board Committees: The Audit, Sustainability, 
and People & Remuneration Committees review 
risk management reports covering risks, controls 
and actions to manage risks to the business 
within their respective remits.

The 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, and oversight of the 
internal control and risk management system’s 
effectiveness.

The Sustainability Committee assists the Board 
in the effective discharge of its responsibilities 
in relation to safety, health, environment and 
community (SHE&C) matters including how 
the Company is reporting and managing risks 
relating to SHE&C and its requirements for 
internal notification, investigation, reporting  
and continuous improvement.

The People and Remuneration Committee assists 
the Board in discharging its responsibilities 
in relation to the remuneration of directors, 
executives and employees, succession 
planning, the establishment and monitoring 
of the Employee Value Creation Policy, and 
oversight of risk relating to people performance 
management, Company culture, succession 
planning, capacity and capability, and diversity 
and inclusion. 

The Board retains direct accountability and 
oversight of all material risks outside the 
Board Sub-Committees’ remits. These include 
risks relating to mergers and acquisitions, the 
Company’s growth strategy, sovereign uncertainty, 
Mineral Resources and Ore Reserves estimates, 
macro-economic and market-related risks.

Executive Leadership: The Executive 
Leadership team is responsible for the effective 
implementation of the risk management 
framework and system of control for identifying, 
assessing, managing, and reporting risk across 
the Company. The Executive leadership team 
reviews and approves the risk profile for the 
organisation and ensures Assets and Corporate 
Functions embed risk management process and 
practice into business systems and processes.

Corporate Risk Function: The Corporate 
Risk Function supports and coordinates the 
implementation of the risk management 
framework, embeds risk management into core 
business processes, and builds risk management 
capability and a risk-aware culture across the 
business. The Corporate Risk Function oversees 
OZ Minerals’ Risk Management Framework and 
develops, governs, supports and reports on the 
effective implementation of risk management  
to the Executive Leadership Team, the Board  
and its sub-committees.

Identify and Implement
    Risk and Control Owners apply Process and 
      Performance Standards to identify risks, 
        implement controls and verify control 
          effectiveness

The first line of defence
Process Standards define the approval  
escalations between the Board, CEO,  
Corporate Functions and Assets based on  
risk. The Risk Management Process Standard  
outlines the mandated process for escalation  
and the roles that organisational authority  
levels play. Risk responsibility for identifying, 
assessing, managing and reporting resides 
with all employees who are responsible for 
considering risks when making key decisions, 
implementing controls and monitoring risks 
during their activities. 

The second line of defence
The senior leadership of the Assets and 
Corporate Functions assure compliance  
with the minimum controls in OZ Minerals’ 
Performance and Process Standards and  
provide subject matter expertise and insights  
to support the delivery of the standards.

The third line of defence
All Process and Performance Standards are 
subject to the Audit and Assurance Process 
Standard, where compliance against the 
Standard and opportunities for improvement 
are monitored by the Corporate Audit Function 
in addition to the self-assurance activities 
undertaken by the Assets and Corporate 
Functions themselves. The Internal Audit and 
Assurance Function provides independent 
assurance over the governance, compliance  
and internal control system and processes  
across the business.

The fourth line of defence
External Audit provides an independent 
assurance that the internal control system  
is adequate, and that OZ Minerals’  
operations comply with the minimum 
requirements of relevant regulatory,  
legislative and associated standards.

The table below details inherent risks that could materially impact OZ Minerals’ ability to deliver its Strategy and Business Plans.

Risk 

Mitigation/actions

Threat
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 the 
execution of our strategy and the ability of our assets  
to operate efficiently.

Opportunity
Climate change, combined with regulatory change, also  
has the potential to be a catalyst for growth in industries 
that require copper and could result in upward pressure  
on copper prices.
Ability to proactively use lower-emission sources of  
energy, efficient production and distribution processes,  
new technologies, water and energy efficiency, and 
proactive participation in the carbon market can result  
in reduced operating costs, increased production capacity, 
an improved revenue and liquidity position. 
This can also increase reputational benefits and create 
value for our key stakeholders.

Threat
Political uncertainty, trade protectionism, and changes  
in relations between countries can impact the Company’s 
ability to access resources and markets needed to achieve 
our strategy.

Opportunity
Continue to develop the exploration pipeline and resource 
portfolio. Assess non-organic acquisitions in relatively 
politically stable jurisdictions as opportunities present.

OZ Minerals is committed to reducing the energy  
and water intensity of its operations, developing 
innovative practices in relation to chemical processing, 
and being more efficient in its transportation and 
processing activities.
The Company’s power strategy is focussed on the 
four key elements for all its operations: Distribution, 
Generation, Procurement, and Demand Management. 
Initiatives are underway across operations to reduce the 
Company’s environmental footprint, including energy 
intensity, water use, waste management, and transport 
and logistics.
OZ Minerals focuses on reducing carbon emissions, 
investing in low emissions technologies, managing 
climate-related threats and opportunities, and working 
collaboratively with others to contribute to identify 
improvements and transformational change.
OZ Minerals has published a Climate Change Statement 
on its website which commits to playing its part in 
achieving net-zero carbon emissions by 2050.
OZ Minerals has prepared a roadmap for reporting  
its integrated climate change risks and climate-related 
financial disclosures in line with the Task Force 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.

OZ Minerals regularly monitors geopolitical and 
macroeconomic trends to understand potential impacts 
on our business and seeks to identify mitigating actions 
as soon as possible, if practicable.
The Company also engages with governments and other 
key stakeholders to understand and communicate the 
impact of any potential impacts from changes in trade  
or resource policies.

Context 

Strategic

Climate change
OZ Minerals recognises that the physical 
and non-physical impacts of climate change 
may affect its assets, productivity, the 
markets in which it sells its products, and 
the communities in which we operate. Risks 
related to the physical impacts of climate 
change include acute risks resulting from 
increased severity of extreme weather events 
and chronic risks resulting from longer-term 
changes in climate patterns. 
Non-physical risks arise from a variety of 
policy, regulatory, legal, technology, financial 
and market responses to the challenges 
posed by climate change and the transition 
to a lower-carbon economy.

2019 Risk Trend Analysis

   Increasing Risk

Community, investor and regulatory 
standards and expectations in relation  
to climate change continued to increase 
during 2019.

Macroeconomics and Geopolitics
OZ Minerals currently operates in  
Australia and Brazil, has exploration  
activities in multiple countries and may 
consider operating in new locations to  
access desired resources. The Company’s 
customers and suppliers are also located  
in international markets. 
Geopolitical and macroeconomic 
developments have the potential to restrict 
our ability to access resources in certain 
countries or effectively trade in markets.  
Any restrictions will impact our ability  
to realise our strategy as competition for 
resources intensifies, existing reserves are 
depleted, and supply sources become  
more expensive to develop.

2019 Risk Trend Analysis

   Increasing Risk

OZ Minerals’ exposure to macroeconomics 
and geopolitics risks are anticipated to 
increase in the short to medium term due to 
heightened political and policy uncertainty.

Context 

Risk 

Mitigation/actions

Single material Operating Asset 
The Prominent Hill mine generates most  
of the Company’s income and cash flow. 
The occurrence of any inherent operational 
risks can interrupt the asset’s operations  
and performance to meet or exceed  
planned objectives.

Threat
Operating only one material operating asset exposes  
the Company to financial and operational risks. 
Business interruptions may arise from several 
circumstances, including major operational failures  
such as significant safety or underground incidents  
and major infrastructure failure.

2019 Risk Trend Analysis

  Decreasing Risk

Ramp-up of Carrapateena operations in 
2020 and beyond will decrease the risk. 
Brazil Hub strategy now also in place  
and execution underway. 

Opportunity
The ability to develop and execute new projects such  
as Carrapateena safely, on time, and within budget, 
enhances the Company’s income, cash flow, balance  
sheet, and reputation with all key stakeholders. 
A strong balance sheet and liquidity position allows  
the Company to pursue its growth pipeline.

Growth and development
A key element of the Company’s Strategy is 
growth through acquisition or development 
of value accretive copper assets.
OZ Minerals’ ability to create value for 
key stakeholders by successfully executing 
mergers, acquisitions and divestments  
may vary.

2019 Risk Trend Analysis
       No Change in Risk

There are no changes identified that  
are expected to significantly increase  
OZ Minerals’ exposure in this area. 

Project Execution and Delivery
Successful execution of OZ Minerals’  
growth Strategy depends on its ability  
to deliver projects on time, safely, within 
budget and scope. The Company’s ability  
to deliver projects successfully may vary.

2019 Risk Trend Analysis
       No Change in Risk

There are no changes identified in the 
risk environment that are expected to 
significantly increase OZ Minerals’ exposure. 
Whilst additional execution capability has 
been developed through delivery of the 
Carrapateena project, each project remains 
unique and carries varied and specific 
challenges. 

Threat
In an environment of prospective commodity prices  
and expected long-term shortages in copper supply,  
OZ Minerals competes with other entities to acquire and 
develop projects that generate superior stakeholder value.
Divestment and acquisition activity may result in value 
destruction by realising less than the fair value for 
divestments or paying more than fair value for acquisitions. 
This could result in pressure on the Company’s liquidity 
position and/or reduce the Company’s ability to deliver  
its growth Strategy.

Opportunity
The existence of large resources at the Prominent Hill, 
Carrapateena, Musgrave, Carajás and Gurupi Provinces, 
other exploration joint ventures, and the prospectivity  
of the Gawler Craton provide the Company with options  
to deliver on the growth Strategy.
OZ Minerals’ success in an acquisition, merger, or 
divestment on good terms will provide sustainable  
future cash flow and/or future growth optionality.

Threat
Mine development projects are inherently exposed to  
risks relating to scope definition, cost estimation accuracy, 
and a number of other external factors that present threats 
to a project’s cost, efficiency, and profitability. These are  
not all within the Company’s control.
A delay or overrun of a project schedule could negatively 
impact the Company’s profitability, cash flows, asset 
carrying values, growth opportunities, and reputation  
with key stakeholders.

Opportunity
An ability to develop projects safely, on time, and within 
budget enhances the Company’s reputation, license to 
operate, stakeholder confidence, and increases cash flow 
and returns to all stakeholders. 
An increase in cash flow enables the Company to pursue 
its growth Strategy and provide value across its five 
stakeholder pillars.

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 of available ore to the operations.
The Company has an active program that focuses on 
using trigger action response plans to maintain the 
ongoing stability of the open pit walls as the pit is now 
used for trucks carrying ore to exit the underground 
mine. The OZ Minerals maintenance and engineering 
team has developed robust procedures and practices 
to ensure they are operating the processing plant with 
minimal disruption and at high throughput levels.
Progress the development and ramp-up of an additional 
significant operating asset at Carrapateena.
The Company has also developed a strategy to develop 
the Carajás province in Brazil via a low risk, modest 
capital processing hub strategy where existing processing 
infrastructure is serviced by several small mines, one  
of which, Pedra Branca, is now in construction. 

OZ Minerals has a clear pipeline of projects and gated 
plans which ensure a disciplined approach to leverage 
the potential of the resource base.
Each opportunity is evaluated with due care and relies 
upon expert opinion, both internal and external where 
necessary, to ensure that any potential transaction is 
value accretive across all stakeholders.
OZ Minerals maintains a segregated approach to its 
identification and then subsequent review of potential 
transactions and projects to ensure appropriate 
governance is applied over the assessment of financial 
risk and returns.
OZ Minerals maintains a robust framework to deliver 
growth through Merger, Acquisition and Divestments  
and Exploration Process standards.

OZ Minerals ensures its projects go through a process  
of internal and independent external review to verify  
the engineering, technical, and financial scope definitions 
and other assumptions.
The Company manages project costs through sound 
procurement practices and governance. OZ Minerals 
maintains a strong focus on contractor management 
and undertakes rigorous third-party due diligence and 
assurance as part of its engagement.
Stakeholder management in project development is  
a focus from the start, with a clear understanding of  
who we are working with and a co-operative approach 
to engagement.
Project approval, monitoring and progress status 
evaluation are performed in line with OZ Minerals’  
project governance framework through the Process  
and Performance Standards.

Context 

Risk 

Mitigation/actions

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

2019 Risk Trend Analysis

  Decreasing Risk

While power infrastructure may be 
vulnerable to extreme weather events, 
actions have been taken by the South 
Australian Government and private 
companies to shore up generation stability 
since the weather event in 2016 which 
interrupted supply in South Australia.

International Operations

Sovereign uncertainty  
and inherent risk
The Company’s operations are located  
across several jurisdictions, which  
exposes the Company to a wide range  
of economic, political, societal, and 
regulatory environments.
OZ Minerals recognises the value of positive 
engagement with a range of stakeholders 
and seeks to develop collaborative and 
mutually beneficial partnerships through  
our partner-to-operate strategy.

2019 Risk Trend Analysis
       No Change in Risk
OZ Minerals’ exposure to sovereign 
uncertainty is expected to remain  
relatively stable.

Market

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

2019 Risk Trend Analysis
       No Change in Risk

There are no changes identified that  
are expected to significantly increase  
OZ Minerals’ exposure.

Threat
OZ Minerals competes with other power users for a 
competitively priced uninterrupted power supply within  
the prevailing environment of volatile electricity prices  
and potential power shortages. 
Unavailability of power can disrupt operational 
performance, revenue, cash flow, employee engagement, 
and value creation to stakeholders. 

The Company has developed a power strategy for the 
Gawler Craton to align with its business strategy and 
demand needs. This is focussed on four key elements: 
Distribution, Generation, Procurement, and Demand 
Management. The Hill to Hill Project will both secure  
and extend distribution options within the region. 
The Prominent Hill and Carrapateena electricity  
supply contracts ensure energy requirements are met.

Opportunity
OZ Minerals can work collaboratively with other  
companies in the region to share infrastructure or  
provide back-up arrangements.

Threat
Adverse actions by governments and others can result in 
operational/project delays or loss of our license to operate. 
Other potential actions can include expropriation, changes 
in taxation, and export or foreign investment restrictions  
- which may threaten the investment proposition, title,  
or carrying value of assets.
Legal and legislation requirements with respect to  
policies such as tailings dams operations, energy, climate 
change, and mineral law may also change in a way that 
increases costs.

Opportunity
Proactive engagement with governments, communities,  
and other stakeholders can increase access to new 
resources, support stable and predictable investment and 
operational environments, and shape mutually beneficial 
policies and legal/regulatory frameworks. 

Threat
Concentrate marketability depends on global mine  
supply, smelter demand, concentrate grades, and  
impurities in the product. OZ Minerals’ concentrate 
contains copper, 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 may impede the importation of 
concentrate into those jurisdictions and result in  
additional processing or treatment requirements  
related to the ore, tailings or concentrates, or  
challenges with selling, transporting or importing  
OZ Minerals’ concentrates in various jurisdictions.

Opportunity
Short to medium term global copper demand is forecast 
to be higher than copper mine supply due to existing and 
new uses of copper such as for electric vehicles. Increase 
in copper demand will increase the Company’s cashflow 
position and enables the Company to pursue its growth 
pipeline to create value across all stakeholders.

The Company’s operations comply with policies and 
standards which provide a core component of the 
Company’s governance framework on risk management, 
human rights, cyber threat, data privacy, business 
integrity, and external communications.
OZ Minerals continues to develop and maintain long-
term relationships with a range of international and  
national stakeholders.
OZ Minerals monitors jurisdictional, including sovereign 
risks, and take appropriate action.

OZ Minerals has developed customised solutions in 
partnership with customers. These match smelter demand 
and production from OZ Minerals’ mines to concentrate 
grade and timing, along with a range of controls to 
manage impurity levels.
OZ Minerals has a number of marketing options in 
addition to this, including, but not limited to, ore 
blending, concentrates blending, and additional flotation 
treatment in the processing plant. It also maintains 
technical know-how in relation to its concentrate 
treatment plant technology.
OZ Minerals maintains a diverse customer portfolio 
to mitigate against the risk of regulatory changes to 
importation requirements.

DIRECTORS' REPORT

Context 

Risk 

Mitigation/actions

For revenue in 2019, OZ Minerals swapped the  
average forward price on each copper concentrate  
sale to a fixed price in the period of sale. 
In 2016 OZ Minerals entered into gold forward  
contracts to fix the gold price on 75% of the  
estimated gold content of the Prominent Hill gold  
ore stockpile to mitigate downside risk. 
The remaining hedge book covers about 64% of 
estimated annual gold sales in 2020 and 2021.
OZ Minerals does not actively hedge exchange  
rate exposures.
OZ Minerals aims to operate its mines with a low cost 
of production relative to global copper producers as a 
form of natural hedge. This ensures resilience to low 
commodity prices and an ability to maximise margins 
during high commodity prices.

OZ Minerals’ clear business strategy, capital discipline, 
and a conservative capital structure encourage lenders 
and shareholders to continue investing in the business 
and to attract new capital on attractive terms and  
at competitive pricing.
OZ Minerals manages debt maturities to spread 
repayment and minimise refinancing risk.
OZ Minerals manages credit exposure to ensure the 
Group capital structure is not compromised if a finance 
counterparty fails to perform its financial obligation.

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 adopts a more collaborative and integrated 
partnership with its key contractors to ensure alignment 
and the delivery of mutual value.

Commodity prices and exchange rates
Commodity prices are driven by global 
market demand and supply. Exchange  
rates are also influenced by international 
economic activity and geopolitical factors. 
The timing, direction and the extent  
of commodity price and exchange  
rate movements is uncertain.

Threat
OZ Minerals is a price taker in the global commodities 
market and in the Brazilian Real and Australian Dollar 
currency markets.
A decrease in commodity prices or adverse foreign 
exchange rate movements will reduce cash flow, 
profitability, and total shareholder returns. Long-term  
price volatility or sustained low prices may adversely  
affect access to capital.

2019 Risk Trend Analysis
       No Change in Risk
We do not anticipate any material  
change in the Consolidated Entity’s  
exposure to commodity prices and  
exchange rates in 2020.

Capital Management

Opportunity
An increase in commodity prices and/or favourable  
foreign exchange rate movements generates positive cash 
flow and strengthens the Company’s liquidity position, 
enabling the Company to pursue value creation growth 
options and/or increase total shareholder returns.

Strong balance sheet and liquidity
The Company maintains a strong balance 
sheet and appropriate liquidity position to 
fund its operations and capital investment 
plans through the global economic cycles. 

Threat
The Company’s ability to refinance and attract sufficient 
new capital to fund operations and growth through an 
economic downturn could be compromised by a weak 
balance sheet.

2019 Risk Trend Analysis
       No Change in Risk

The risk is expected to remain relatively 
stable. The Board intends to maintain  
a conservative gearing position as debt  
is drawn.

Commercial

Contract Management
Many aspects of the Prominent Hill, 
Carrapateena and Carajás operations,  
as well as the Company’s exploration  
and development activities, are conducted  
by contractors.
Contractors play a major role in delivering 
the Company’s production and cash 
positioning - these relationships may not 
always develop as planned. The Company’s 
workforce is made up of a combination  
of permanent employees and contractors. 
OZ Minerals recognises the importance of 
appropriate contractor selection and effective 
management of contractors from a safety, 
cost, quality, schedule, and performance 
perspective to the success of our business. 

2019 Risk Trend Analysis
       No Change in Risk

There are no changes identified that  
are expected to significantly increase  
OZ Minerals’ level of exposure. 

Opportunity
Strong internal capital management and favourable  
market conditions could increase liquidity, balance  
sheet strength, and increase total shareholder returns.

Threat
The operating results of OZ Minerals is heavily  
dependent on the performance of its contractors.
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.

Opportunity
Partnering with key suppliers allows work to be  
performed within an environment of mutual trust, 
commitment to shared goals, and open communication. 
It establishes a working relationship based on a mutually 
agreeable plan of cooperation and teamwork. Through 
close communication and establishing mutually agreeable 
goals, outstanding results can be achieved. The objective  
is a shared value outcome between all parties.

Context 

Risk 

Mitigation/actions

Exploration, Resource and Reserve

Mineral Resource and Ore Reserve
Mineral Resource and Ore Reserve estimates 
involve areas of significant estimation and 
judgment that, if changed, could result in the 
need to restate Ore Reserves and mine plans. 
Also, the success of the Company’s 
exploration activity may vary due to the 
inherent risk and uncertainty involved in 
identifying new deposits and developing 
orebody knowledge to our new and  
existing operations.

2019 Risk Trend Analysis
       No Change in Risk

There are no material changes identified  
that are expected to significantly increase  
OZ Minerals’ level of exposure in 2020.   
As the Company continues to grow the risk 
level may increase commensurate with the 
quantum of resource opportunities.

Operational

Tailings Storage Facility (TSF)
Tailings Storage Facilities are dynamic 
structures and maintaining their integrity 
requires consideration of a range of factors, 
including appropriate engineering design, 
quality construction, ongoing operating 
discipline, and effective governance 
processes.

2019 Risk Trend Analysis
       No Change in Risk

There are no changes identified that  
are expected to significantly increase  
OZ Minerals’ level of exposure. OZ Minerals 
does not operate upstream tailings facilities. 

Geotechnical Failure
The open pit and underground mining 
operations are 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.

2019 Risk Trend Analysis
       No Change in Risk

There are no changes identified that  
are expected to significantly increase  
OZ Minerals’ level of exposure.

Threat
The preparation of these estimates involves the  
application of significant judgment and no assurance 
of mineral recovery levels, or the commercial viability 
of deposits can be provided. The Company reviews and 
publishes its reserves and resources annually.
The threat that new information on resource and reserves 
come to light means that the economic viability of 
some Ore Reserves and mine plans may be estimated 
downwards. As a result, operations and projects may 
be less successful and of shorter duration than initially 
anticipated, and/or the asset value may be impaired.
Also, the inability to discover new resources or  
projects could undermine the strategy of future growth.

Opportunity
The volume of ore in reported reserves/resources is based 
on the geological, commercial, and technical information 
available at the date of the report that is, by its nature, 
incomplete. As new information comes to light, the 
economic viability of some Ore Reserves and mine plans 
can be restated upwards. As a result, projects may be more 
successful and of longer duration, than initially anticipated.
In addition, the discovery of a new viable orebody can 
significantly improve future growth options.

Threat
The collapse of a TSF has the potential to impact the safety 
of employees and community in the vicinity of the area, 
Company growth, the mine operation, the environment  
and long-term Company reputation.

Opportunity
Reduction of processing plant waste into TSFs using mining 
ore preconcentration technology. In the Carajás, reducing 
the processing plant waste going into the TSF by using 
the soon to be exhausted Antas Pit as a TSF (subject to 
approvals). This will reduce the need to create and license 
a new TSF area.
Optimise the expansion of the Prominent Hill filter stack 
tailings storage capacity to reduce waste disposal into the 
TSF as the pilot for the organisation’s continuous pursuit 
for more sustainable tailings disposal methods in Australia.

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.  
Each estimate is reviewed by a committee of peers  
to challenge the applied assumptions.
The Company’s production plan is based on published 
reserves and resources.

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 license requirements, 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.

Threat
The concurrent mining of multiple underground areas  
at the Prominent Hill mine will lead to increased 
underground mining activities. 
The Carajás mine open pit depth will increase as mining 
concludes. Failure of underground operations or open pit 
walls can result in loss of life, reputational damage, loss  
of licence to operate, disruption to operations, increased 
costs or environmental damage.

OZ Minerals operates systems that prevent, monitor, 
and respond to changes in geotechnical structures in 
the open pit and underground 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.
The Company has an active program which focuses 
on using trigger action response plans to maintain the 
ongoing stability of the underground and open pit walls. 

Opportunity
Creating a safe work environment by removing people from 
unsafe activities and transforming underground mining by 
embedding digitalisation and automation technologies.

Safety, health, environment and community (SHEC)

Operational safety and health  
OZ Minerals is committed to high  
standards in the safety of its operations, 
including employees, contractors, and  
the communities in which we operate. 
Protecting the health and wellbeing of  
our workforce is vital to meet current  
and future growth requirements. 

2019 Risk Trend Analysis
       No Change in Risk

OZ Minerals’ exposure to operational  
safety and health risks is expected to  
remain relatively stable.

OZ Minerals is committed to the safety of its people, and 
all work processes have a high health and safety focus.
OZ Minerals operates in partnership with its contractors 
and is actively building a shared health and 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 health 
and safety incidents, has delivered significant successes 
and resulted in a sustained reduction in the severity  
of injuries.
OZ Minerals is continuing to build partnerships with  
local and state Governments and other miners operating 
in the regions it operates, to support projects that 
contribute to improving employee and community safety.

Threat
OZ Minerals undertakes operations in areas that may 
pose health and safety risks including, but not limited to, 
handling explosives; underground operations subject to 
rockfall; infrastructure, tailings facilities, extreme weather 
events, endangered flora or fauna, areas of cultural 
heritage significance, confined spaces; areas where  
heavy and light vehicles interact; manual handling;  
and operating at heights. 
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. Similarly, 
drive-in and drive-out operations introduce inherent  
safety travel risks to employees and contractors.
Health and safety incidents may lead to serious injuries, 
loss of life to employees, contractors and members of 
the community. Also, incidents may result in reputational 
damage, loss of license to operate, disruption to operations, 
increased costs or environmental damage.

Opportunity
Consistently exceeding or meeting our health and safety 
commitments can enhance the Company’s reputation 
and working relations across all key stakeholders and 
contributes to sustainable growth.
This can also enable the Company to gain a competitive 
advantage on minerals resources, funding, and a skilled 
workforce to sustain the Company’s growth strategy. 

Mine closure and rehabilitation
The Company operates under a range of 
environmental regulations and guidelines, 
including rehabilitation of disturbed areas 
that are no longer required for operational 
purposes (closed mines).
Determining the closure and rehabilitation 
provisions is a complex area requiring 
significant judgment and estimates, 
particularly given the timing and quantum  
of future costs, the unique nature of each 
mine site, and the long timescales involved.

2019 Risk Trend Analysis
       No Change in Risk

There are no changes identified for these 
risks that are expected to significantly 
increase OZ Minerals’ level of exposure.

Threat
The Company is required to close its operations and 
rehabilitate the land affected by the operation at the 
conclusion of mining and processing activities. 
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. 

Opportunity
Excellent performance on mine closure, rehabilitation  
and legacy management of closed sites can enhance  
OZ Minerals’ reputation and enable the Company to gain 
and maintain access to land, resources, skilled work force 
and external funding, so the Company can continue to 
pursue its growth strategy and establish new projects 
with the support of local communities and other key 
stakeholders. 

Estimates of mine closure 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.
OZ Minerals complies with the South Australian 
Government’s Program of Environmental Protection 
and Rehabilitation (PEPR) to address mine closure 
requirements in line with the Department of Energy  
and Mining regulations. In Brazil, the Company complies 
with the National Mining Agency, and the Environmental 
Agency of Para State (SEMAS) regulations to address 
mine closure requirements.
OZ Minerals maintains a strong and effective operational 
monitoring program including groundwater, cultural 
heritage sites and flora and fauna habitats.

OZ Minerals’ environmental performance and management 
of environmental impacts on the communities in which it 
operates is critical to creating sustainable social value.
Non-compliance with environmental regulation has the 
potential to impact Company growth, damage reputation, 
and could result in damaged relationships with key 
stakeholders and loss of licences to operate. 

Opportunity
Effective environmental-related risk management  
can contribute to long term business, social, and  
environmental benefits, including long term business 
resilience, improved community relations, reputational 
benefits, and maintenance of operating licences.

Threat
OZ Minerals or its partners may engage in activities  
that impact the environment, communities, human  
rights, or social wellbeing. 
This can affect OZ Minerals’ relationships with or  
be viewed negatively by the community and other 
stakeholders. A loss of stakeholder support could result  
in the inability to maintain good relationships, loss  
of social license or permit to operate, loss of business 
opportunity, land tenure or significant delay in project 
approval or delivery. 

Opportunity
Superior social performance allows the Company to  
gain and sustain land access and enables the Company  
to develop new projects and deliver its growth strategy  
to the benefit of all key stakeholders.

Managing and Protecting  
the Environment
There is growing pressure on and 
competition for environmental resources, 
such as biodiversity, water, and air. Our 
operations and growth Strategy depend  
on obtaining and maintaining the right  
to access these environmental resources. 
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 it operates.

2019 Risk Trend Analysis
       No Change in Risk

OZ Minerals’ exposure to environmental  
risks is expected to remain relatively stable. 

Maintenance of community  
relations and good title
OZ Minerals is committed to high  
standards of stakeholder engagement  
and social performance by its employees  
and contractors. 
Building and maintaining strong supportive 
relationships and partnerships with host 
communities in the areas where it operates 
drives value creation for both the business 
and communities. 
The Company seeks to deliver long-term 
benefits to local communities and other 
stakeholders by engaging and collaborating 
with local communities, understanding the 
social impacts its, and reducing the adverse 
effects of its activities.

2019 Risk Trend Analysis

   Increasing Risk

OZ Minerals’ exposure to community  
and its license to operate is assessed as 
increasing due to societal and political 
requirements generally as well as 
expectations for managing exposures  
in the Gurupi Province in Brazil.

The OZ Minerals Risk Management 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 OZ Minerals’ 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 
areas such as surface water, groundwater, 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.

The Company has a Social Performance Standards  
which sets out the minimum standards assets are 
required to meet.
Local level access, compensation and benefit  
agreements are in place with land connected and 
Indigenous stakeholders affected by exploration and 
operational mining activities. Local level agreements 
are developed in collaboration with stakeholders 
to demonstrate Free, Prior and Informed Consent. 
Agreements are updated as required.
The Company has controls in place to ensure compliance 
with the Prominent Hill 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 licenses which 
allow it to operate. 
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. The Company retains good relations with 
the local community.  
In the Carajás province, OZ Minerals works in partnership 
with stakeholders including the different municipalities 
where its project is located, in support of the local 
communities.

DIRECTORS' REPORT

Context 

People and Culture

Attracting and Retaining Talent
OZ Minerals’ competitive advantage lies in  
its agile and innovative culture. Attracting 
and retaining great people with the right 
skills and behaviours both now and for  
the future is core to our success.

2019 Risk Trend Analysis
       No Change in Risk

OZ Minerals’ exposure to this risk is  
relatively stable during FY 2019 and there  
are no indicators identified that are expected  
to significantly increase OZ Minerals’ level  
of exposure at this time.

Human rights and ethics

Human rights and ethics 
OZ Minerals’ activities are exposed to 
human rights, ethics, and social well-being 
expectations. Our operations and supply 
chain are subject to human rights, ethics,  
and employment conditions, which may  
vary from time to time.
The Company recognises the potential for 
human rights exposures and risks in all 
jurisdictions and is committed to working 
broadly to promote respect through 
stakeholder engagement, collaboration, 
advocacy, and contribution to public  
policy development. 

2019 Risk Trend Analysis

   Increasing Risk

OZ Minerals’ level of exposure to risks 
associated with human rights and ethics 
requirements has been assessed as 
increasing due to increasing community and 
political requirements and expectations, as 
well as its expansion into new jurisdictions.

Regulatory and Legislation

Compliance, regulatory and legislation
OZ Minerals’ regulatory and social licence 
are dependent upon complying with laws, 
regulations, guidelines and recommendations 
including in relation to anti-bribery and 
corruption, taxation, data privacy, land 
access, native title, health, safety and 
environment, human rights, modern  
slavery, and local regulations or standards.

2019 Risk Trend Analysis
       No Change in Risk

There are no changes identified that  
are expected to significantly increase  
OZ Minerals’ exposure, except for  
climate change and human rights.

Risk 

Mitigation/actions

Threat
The inability to attract or retain key talent would  
constrain the Company’s ability to deliver its Business  
Plan and Strategy.

Opportunity
Leveraging a powerful and purpose-driven employee value 
proposition to attract and retain a diverse, inclusive, and 
engaged workforce will deliver a competitive advantage to 
the Company, enable it to deliver its growth Strategy, and 
add value to all stakeholders.

Threat
OZ Minerals’ operations or its partners’ may engage in 
activities that may be perceived to or actually impact 
human rights or social wellbeing. 
This can affect OZ Minerals’ relationships and reputation 
with all key stakeholders. A loss of key stakeholder support 
could result in an inability to access new resources, loss 
of new business opportunity, loss of licenses, permit or 
approval, delays in project approvals, shareholder activism, 
society activism, or litigation.

Opportunity
OZ Minerals’ operations or its partners’ activities  
have the potential to improve the lives of stakeholders  
and host communities. Application of local enterprise, 
partnering-based local level agreements and health and 
wellbeing programs have the potential to contribute  
to the development of host communities and to 
improvement in key education, health and wellbeing 
performance indicators.

OZ Minerals mitigates this threat and leverages this 
opportunity through the following core People priorities:
 / A strong and purpose-driven Employee Value 
Proposition to attract and retain the best.

 / An inclusive culture that enables both demographic 

and cognitive diversity and the innovation that comes 
with it.

 / Modern, flexible working arrangements that reflect  
the future nature of work and promote wellbeing.

 / Agile performance management processes that 
promote a culture of continuous development.

 / Professional and leadership development to enable  

our people to do the best work of their careers.
 / Regular employee engagement pulse checks and  

an ongoing focus on culture.

 / A strategic workforce planning approach across all 

operations to identify and manage current and future 
workforce requirements.

Maintain an up to date human rights and modern  
slavery training and awareness program across all 
business areas.
OZ Minerals’ employees, contractors, and partners in 
all geographies are required to operate in compliance 
with the Company’s How We Work Together Principles, 
Policies, Process and Performance Standards and its  
Code of Conduct. 
Independent review of operations’ compliance with  
OZ Minerals’ Performance Standards and Company 
Policies that encompass working in a manner that is 
consistent with the following, to provide minimum 
requirements and expectations to comply with  
relevant laws: 
 / the Universal Declaration of Human Rights
 / obligations of corporations set out in the UN  

Guiding Principles on Business and Human Rights 
 / UN Voluntary Principles on Security and Human Rights.

OZ Minerals continues to improve its understanding  
and management of Modern Slavery related risks in  
its operations and supply chain.   

Threat
The Company’s activities or those of our partners could 
result in actual or perceived breaches of legal, regulatory, 
ethics or compliance obligations. 
Non-compliance with laws and regulations could lead to 
fines and penalties imposed against the Company, delay  
on projects, loss in share price value, loss of land tenure,  
or loss of social licence to operate, permits or approvals. 
Other impacts could include damage to Company 
reputation from all key stakeholders.

Opportunity
Complying with laws and regulations and maintaining  
a high ethical and social performance standard enables  
OZ Minerals to gain and maintain access to resources, 
expand provinces, investment opportunities and create 
value for key stakeholders.

OZ Minerals employees, contractors, and partners 
operate in compliance with the HWWT principles,  
Policies, Global Process and Performance Standards. 
The governance framework provides minimum 
requirements to comply with relevant laws and 
legislations.
OZ Minerals continues to improve its understanding 
and management of modern slavery related risks in its 
operations and supply chain and to identify associated 
opportunities by maintaining up to date modern slavery, 
anti-bribery and corruption, continuous disclosure and 
code of conduct training and awareness.
Continue to track and monitor key changes to legislation 
and regulations and respond to new requirements.

REMUNERATION O VERVIEW

Letter from the  
Chairman of the People  
and Remuneration committee

Dear Shareholders,

On behalf of the Board of Directors, I am pleased to provide you with the 2019 Remuneration  
Report for OZ Minerals.

2019 was another year of strong performance for the Company, including: 

 / Construction and delivery of the Carrapateena mine, which will ramp up to full production over  

the next 12 months. 

 / Continued reliable performance at the Prominent Hill mine where a significant existing resource 

supported a further mine life extension to 2031 and an expansion study which is underway.

 / Development of the Carajás Hub strategy in Brazil with construction starting in December 2020  

of the Pedra Branca underground mine which will become the first spoke in the Carajás  
processing hub.

 / The consolidation and embedding of our culture and governance processes.

 / A strong NPAT result of $163.9 million.

Shareholders benefited from the Company’s performance with dividends of 23 cents per share  
and annual shareprice growth of 20%.

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 Directors’ Report.

Remuneration outcomes in 2019
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 2019

 / Executive salaries were increased as detailed in last year’s report. 

 / In March of 2019 we were saddened and confronted by a fatal incident involving an ElectraNet 

sub-contractor who was a helicopter pilot working on stringing the power line to our Carrapateena 
project. His death has had a profound effect on the whole Company, especially the Carrapateena 
team. To acknowledge this tragedy, and pay our respects, the Board with the full support of the 
Management Team has chosen to rate the safety component of the 2019 STI plan at 0% payment.

 / The strong performance of the Company against the remaining KPIs set by the Board for the 2019 
year resulted in a score of 3.4 out of 5.0. Details of the KPI outcomes can be found in Section 3.2  
of the Remuneration Report.

 / Recognising the strong Company performance and his leadership during 2019, the Board awarded 

70% of the maximum annual short term incentive opportunity to the Managing Director and 
Chief Executive Officer, Andrew Cole. The Company score and achievement of individual stretch 
goals supported short term incentive awards to Warrick Ranson and Mark Irwin of 81% and 75% 
respectively, of their maximum annual short term incentive (STI) opportunity. 30% of STI awards  
will be paid in performance rights vesting after two years. Details of STI outcomes can be found  
in Section 3.2 of the Remuneration Report.

 / The 2017 long term incentive (LTI) plan vested at 100% in December 2019 following a strong 
relative performance of the Company and strong share price performance. This resulted in the 
vesting of 135,446 performance rights to Andrew Cole. 

 / The performance conditions of the 2018 KMP Alignment Plan were satisfied in December 2019 
resulting in the vesting at 100% of 11,400 performance rights to Warrick Ranson and 11,400 
performance rights to Mark Irwin.

Remuneration changes implemented in 2019
As communicated in last year’s Remuneration Report, 2019 saw the implementation of changes to 
our Remuneration Framework to create a greater alignment between executives and shareholders 
over the longer term.

In summary, the key changes implemented were:

 / 30% of an executive’s STI is now paid in equity subject to a two-year holding lock.

 / All-in Sustaining Costs (AISC performance) has replaced the absolute share price performance 

measure for the LTI plan.

 / A two-year holding lock on equity which vests under future LTI plans has been introduced.

 / The scope of malus and claw-back provisions were broadened to include circumstances that  

bring the Company into disrepute, or any catastrophic environmental or safety incident. 

 / 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, 100% of fixed remuneration  
for the CEO and 50% for KMPs and other senior executives. Progress against these five year  
targets can be seen in Section 2.5.5 and 6.3 of the Remuneration Report.

Over the course of 2019 we also conducted a comprehensive market benchmarking exercise in  
Brazil in order to align the Brazilian business with the OZ Minerals Remuneration Framework in  
the context of local market conditions.

Remuneration changes anticipated in 2020
The changes outlined above have had the intended effect of strengthening alignment between 
executives and shareholders and no changes are proposed for our Remuneration Framework in 2020. 

Following a benchmarking review of executive salaries against our stated remuneration positioning 
(median for fixed remuneration and upper quartile for performance against value creation stretch 
goals) we are comfortable that the 2019 adjustments for Warrick Ranson and Mark Irwin were at the 
right level. Their Remuneration will be subject to the Company wide remuneration review for 2020.

Noting that the benchmarking review indicated that the fixed remuneration of the CEO, Andrew 
Cole, was below the median, the Board has resolved to increase his fixed remuneration from 
$850,000 to $900,000 per annum reflecting market conditions and the increases in the scale and 
complexity of the Company. 

Following the 5% adjustment to Non-executive Director fees in September 2018, Director fees will be 
held at their current levels for 2020. We will benchmark Directors’ fees in 2020 with any changes to 
take effect in 2021. Details of Directors’ fees can be found in Section 6 of the Remuneration Report.

The LTI plan total shareholder return (TSR) comparator group is reviewed annually to ensure the 
group best reflects the changing nature of the Company’s operations. For the 2020 LTI plan four 
companies (Capstone Mining, Western Areas, Dundee Precious Metals and Metals X Limited) will be 
removed from the comparator group and replaced with five companies (Jiangxi Copper Company, 
KGHM Polska, Zijin Mining Group, Ero Copper Corp and Boliden AB) taking the total comparator 
group to 15.

In a year of strong performance the Board believes the 2019 remuneration outcomes demonstrate 
alignment with shareholder outcomes. The Board remains committed to a Remuneration Framework 
that develops a culture aligned with the Company’s Value Creation Policies, is performance based, 
supports the Company’s strategic objectives and long-term financial soundness and motivates 
executives to pursue the long-term growth of the Company.

Thank you for your ongoing support of OZ Minerals.

2.0 Remuneration Strategy

2.1 Remuneration Philosophy 
OZ Minerals seeks to attract and retain high performing executives and incentivise them to 
outperform. Our approach to remuneration is to provide executives with a market competitive fixed 
remuneration and to reward out performance through performance-linked, ‘at risk’ remuneration. 
Accordingly, we seek to position the fixed remuneration of our executives at around the market 
median of relevant benchmarks, with the opportunity to earn upper quartile total remuneration  
for delivering outperformance.

2.2 Remuneration Principles
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 build value for all our stakeholders with ‘Creating Shared Value’ at the  
heart of the OZ Minerals Strategy.

Table 2 – Remuneration Principles

Business needs and  
market alignment

Simplicity and equity

Performance and 
reward linkages

Market positioning  
and remuneration mix

OZ Minerals’ remuneration framework is focused on achieving our corporate objectives. 
Remuneration is set with regard to market practices and structured so that outcomes  
are aligned with shareholder returns.

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

A well-designed remuneration framework 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 into account the 
challenges of attracting and retaining high performers in business critical roles, particularly 
in the mining industry. The ‘at-risk’ components of remuneration are based on challenging 
goals designed to incentivise executive KMP to achieve business critical objectives 
and create stakeholder value including shareholder returns. A substantial portion of 
remuneration is paid in equity and ‘locked in’ to encourage focus on long term outcomes. 

Talent management

Remuneration framework 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 practices that 
promote the creation of shared value for stakeholders. We openly communicate these 
practices to shareholders and other relevant stakeholders, and will always be within 
legal, regulatory and industry requirements. The Board has absolute discretion to develop, 
implement and review all aspects of remuneration.

OZ MINERALS2019 ANNUAL & SUSTAINABILITY REPORT56

REMUNERATION O VERVIEW

2.3 Remuneration Framework
The OZ Minerals Remuneration Framework aims to attract great people to deliver the OZ Minerals 
Strategy by offering a balanced approach between fixed and variable (at-risk) pay that incentivises 
both short-term and long-term performance.

Element

Structure

Total Fixed Remuneration 
(TFR)

Base cash salary  
and superannuation.

Performance  
Measures

Link to delivery of 
corporate strategy

Total Fixed Remuneration is 
determined based on factors 
including external market 
benchmarking, relativity 
to peers and individual 
performance. 

Short Term Incentive (STI)

Mix of 70% cash and 30% 
performance rights, with a 
two-year vesting period. 

STI is determined based 
on performance against 
challenging, clearly defined 
and measurable targets.

Long Term Incentive (LTI)

Performance rights  
with a three-year  
vesting period subject to  
an additional two-year  
holding lock period.

LTI is assessed against the 
TSR 70% and AISC 30%.

Minimum Shareholding 
Requirements (MSR)

All executives and senior management are expected to 
accumulate and hold a minimum level of vested shares in 
OZ Minerals over a reasonable period. There are different 
shareholding requirements for each level of management, 
which are expressed as a percentage of their Total Fixed 
Remuneration. 

Fixed remuneration is set 
at a competitive level and 
positioned at market median 
to take into account the 
challenges of attracting and 
retaining high performers in 
business critical roles. 

The short term “at-risk” 
component of remuneration 
is focused on incentivising 
executive Leadership to 
achieve business critical 
objectives and demonstrate 
OZ Minerals desired ways  
of working.

The long term “at-risk” 
component of remuneration 
rewards the delivery of 
shareholder returns and 
a sustainable business 
whilst encouraging decision 
making aligned to long term 
shareholder value creation.

This requirement increases 
the sense of ownership of 
the Company amongst our 
executives and enhances the 
degree to which our reward 
arrangements align the 
interests of our executives 
with that of our shareholders.

2.4 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 ensures 
that executive KMP remuneration remains consistent with the Company’s remuneration framework 
and guiding principles, and considers:

 / The Company’s remuneration philosophy

 / relevant market benchmarks using salary survey data from the Australian and Brazilian 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 behaviors and 

development plans

 / Company strategy, business plans and budgets.

2.5 Executive KMP remuneration components

2.5.1 Remuneration mix

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 ‘at target’ and ‘at maximum’ at-risk remuneration is 
earned, the ratios of fixed to at-risk remuneration for KMP would be as follows.

What is included in total  
fixed remuneration?

When and how is fixed 
remuneration reviewed?

An executive KMP’s 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 from the People & Remuneration Committee. During the year,  
we updated the market benchmarking of executive remuneration conducted last year, 
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.

Changes from last year?

No changes to our approach to fixed remuneration are proposed for 2020. 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.

REMUNERATION O VERVIEW

2.5.3 Short term incentive (STI)

Why does the Board think an STI plan is 
appropriate? 

What are the performance conditions?

Variable performance-based remuneration strengthens the link between pay and performance. The purpose of this plan  
is to make a large proportion of the total 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 which deliver the Company’s Strategy. A reward structure that 
provides variable performance-based remuneration is also a necessary component of a competitive remuneration package in 
the Australian and global marketplace for executives.

The performance conditions that determined STI outcomes in 2019 were: (a) Company key performance indicators (KPIs),  
(b) Individual KPIs and (c) How We Work Together principles (HWWT). 
The Company KPIs in 2019 determined 80% of the STI award for the Managing Director and CEO with individual KPIs 
determining the balance of 20%. The Company KPIs determined 50% of the STI award for the remaining KMPs with the 
balance determined by attainment of individual KPIs (25%) and the demonstration of behaviors exemplifying the HWWT 
principles (25%).

(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 2019 included improving the Company’s operational and financial performance, sustainability 
performance and progressing strategic growth objectives. Further details of the 2019 performance against the KPIs can be 
found in Section 3.2.

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, 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.

c) HWWT 
The How We Work Together principles are the same for all executive KMP and they are based on the following elements:
 / Thinking and acting differently, 
 / Building a culture of respect that enables our people to succeed, 
 / Focusing on partnerships and collaboration, not hierarchy, 
 / Delivering superior results through effective planning and agile deployment,
 / Doing what we say we will do and taking action,
 / Acting with integrity and engaging with our stakeholders

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 any point in between threshold and maximum performance levels.

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

Target performance

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

Maximum performance represents outstanding performance, set at a stretch level.

What is the value of the STI opportunity?

The Managing Director and CEO assesses the performance of each executive KMP throughout the year for achievement 
against their personal performance targets and objectives, 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 other 
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 his direct reports and the day-to-day functioning 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.

What happens to STI awards when 
an executive ceases employment?

If an executive leaves OZ Minerals then the Good Leaver rules 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.  
If an executive leaves as a good leaver, performance rights on foot but unvested remain on foot to vest in the normal  
course. This is at the Board’s discretion and conditional upon the individual performance of the relevant executive.

Have the arrangements changed from  
last year?

Yes. As communicated in last year’s remuneration report, with effect from 2019, 30% of the STI is now awarded in 
performance rights which vest, subject to fulfillment of conditions, two years after award. 
Maximum STI opportunities were also increased for the Managing Director and CEO from 120% to 150% of fixed 
remuneration and for other KMP from 80% to 100%.
Claw back will now also apply to the STI component that is delivered as performance rights and now the Board has greater 
flexibility to claw back awards or shares. For example, the Board may lapse or forfeit awards granted under the STI or LTI plans 
in the event that there is a significant safety or environmental event.

OZ MINERALS2019 ANNUAL & SUSTAINABILITY REPORT60

2.5.4 Long term incentive (LTI)

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

The Company believes that a LTI plan can:
 / focus and motivate employees to achieve longer term outperformance outcomes 
 / 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, aligning them with shareholders  

by linking a substantial portion of their potential total reward to OZ Minerals’ shareholder returns.

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 2019?

A grant was made on 29 May 2019 to all continuing participants in the LTI plan, including the Managing Director and  
CEO. Using a face value approach the number of performance rights granted to each executive was calculated as their  
LTI dollar opportunity divided by the adjusted twenty-day volume weighted average price of OZ Minerals as at the start  
of the performance period. The performance period for the 2019 LTI grant is 1 January 2019 to 31 December 2021.

What was the value of the 2019  
grant for executive KMP?

The two performance conditions, referred to as the vesting conditions are: (a) OZ Minerals meeting the LTI performance 
conditions; and (b) the executive KMP meeting the service condition.
Performance conditions
The LTI plan performance conditions for 2019 are different from 2018 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 measure because it ensures that a proportion of each participant’s remuneration is linked to Value 
Creation and that participants only receive a benefit where there is a corresponding direct benefit to our shareholders,  
as reflected in the share price.
TSR reflects benefits received by shareholders through share price growth and dividend yield and it is the most widely used 
long term incentive measure 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.

The TSR performance hurdle accounts for 70% of the LTI award. Grants in 2018 and 2017  
were subject to the same conditions set out in the table above.

2. All-In Sustaining Costs (AISC) 
AISC is an industry accepted measure of the total operating cost of producing a unit of metal. 
Comparative data will be sourced from Wood Mackenzie’s global copper mine supply summary report, available through 
its database. The annual AISC performance will be recalculated across the full three-year period (total 3-year absolute costs 
divided by total 3-year copper metal production). The comparison will be to the average published TCPS (Total Cash Cost  
+ Sustaining Capex) across that same period. 

OZ MINERALS61

What are the performance conditions? 
(cont’d)

Performance in relation to this hurdle will be measured over the 3 year performance period and will vest in accordance  
with the following table. 

Why were the performance  
conditions chosen?

What is the comparator group?

Nil

50%

Between 50th percentile and 25th percentile (Lowest cost)

Straight line vesting between 50% and 100%

25th percentile or below

The all-in sustaining costs hurdle accounts for 30% of the LTI award. Prior to 2019 30% of the LTI award was subject to 
absolute share price growth over the performance period. Growth of 20% or greater results in 100% vesting. Less than 20% 
no rights will vest.

Service condition
The service condition is met if employment with OZ Minerals is continuous for three years commencing at the beginning  
of the performance period.

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.

The comparator companies selected for the 2019 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?

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. 
If and when these performance rights vest, shares will be allocated (or a cash equivalent amount will be paid) in accordance 
with 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. 
The Board can also adjust awards granted under the STI or LTI plans in the event that there is a catastrophic safety or 
environmental event, in which an adjustment is warranted.

OZ MINERALS2019 ANNUAL & SUSTAINABILITY REPORT62

REMUNERATION O VERVIEW

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

Under the Company’s Securities Trading requirements, 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.

Have the arrangements changed  
from last year?

Yes. As communicated in last year’s remuneration report, with effect from 2019, the absolute share price performance 
measure has been replaced with a strategic financial measure based on All In Sustaining Costs (AISC). 
A holding lock was also introduced on the LTI plan, which requires executives to hold any vested LTI for a period of two years 
beyond the initial three year performance period and thereafter shares which have vested will also be subject to minimum 
shareholding requirements.

(a) Information at 31 December 2019 based on share price at that date. With expected levels of vesting of the deferred equity element of

(b) Includes shares owned and exercisable and performance rights awarded where vesting is only contingent on a service condition being 

satisfied.

2.6 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.

Protocols
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 2019, EY was engaged to undertake an update to the market benchmarking of executive 
remuneration. Their analysis was considered by the People and 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 $27,810 (excluding GST).

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 conditions for grants 
before 2019 are the relative TSR performance consistent with the details in Table 3.7 and absolute share price growth of the Company 
over the relevant performance period as detailed beneath Table 3.8. For 2017 LTI the TSR was assessed independently at 75% and absolute 
share price had an increase of 32.86%, resulting in full vesting of the Plan. For grants from 2019 onwards the vesting conditions are the 
relative TSR and AISC performance. 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 17. Additional details  
are set out in Note 13 to the Financial Statements.

(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.

(c) Performance rights granted under 2018 alignment plan were a one off allocation for retention purposes.
(d) Expiry date does not consider holding lock periods.

4.0 Executive KMP employment arrangements

Remuneration arrangements for executive KMP are formalised in executive service agreements. Each agreement provides for the payment 
of fixed remuneration, performance-related cash bonuses under the STI plan, other benefits, and participation in the Company’s LTI plan.

(a) 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 his relocation costs.

(b) 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. 

(c) Represents direct contributions to superannuation funds. Amounts greater than the maximum superannuation level have been paid and included in cash salary.
(d) 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.
(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 as LTI and STI 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) Reflects actual value of deferred STI which is provided in the form of performance rights. The total value of the deferred STI is recognised proportionally over the period the executive is required  

to provide service.

6.0 Non-executive Director remuneration

6.1 Non-executive Director remuneration policy

SUSTAINABILITY REPORT

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

You’ll find examples of this in practice embedded 
through our 2019 Annual & Sustainability Report 
to reflect how we have integrated sustainability 
into our operations.

Stakeholder Alignment with  
Sustainability Performance Elements 

Creating value for our stakeholders is at the 
centre of OZ Minerals’ Strategy. Our 2019 
Sustainability Report shows how the elements  
of sustainability align with our stakeholders.  
This year, we have also illustrated our 
alignment with the United Nations Sustainable 
Development Goals (SDGs). The elements  
of sustainability at OZ Minerals show how  
we are contributing to specific SDGs. 

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 disclosures. These documents 
are publicly available on our website to make 
specific information more accessible.

This Sustainability Report covers the performance 
of our Prominent Hill and Carrapateena assets, 
and facilities over which OZ Minerals had 
operational control for the full 2019 calendar 
year. Joint ventures which we do not operate 
are excluded.With respect to Antas operations, 
limited data is provided as we are in the process 
of aligning Brazilian sustainability reporting with 
Australian requirements. 

Sustainability at OZ Minerals 
Sustainability management is integrated into 
The OZWay, which governs operating asset 
accountabilities within our devolved operating 
model and our Strategy.

Our Company’s governance framework  
(page 19) consists of Strategy, Performance 
Standards that set the minimum benchmarks and 
expectations of performance for global assets, 
Process Standards that support the operation 
of the business, company policies that show 
the overarching intent within the business and 
enable our stakeholders to hold us to account, 
and the annual business planning process which 
sets the priorities. These all support OZ Minerals 
in being a Modern Mining Company that creates 
value for our stakeholders.

Materiality Matrix

Our process for assessing materiality complies 
with the GRI guidance on materiality and 
completeness when identifying material  
topics and referenced a range of internal  
and external considerations and priorities. 

Methodology

In 2019, we expanded the range of material 
topics from eight to 18 to reflect the different 
operating contexts of our assets as a global 
business. We recognise some topics are 
strongly related, however to better understand 
materiality, we have intentionally separated some 
topics as individually material in our assessment, 
for example, energy, waste and water are linked 
to climate change which is discussed in detail on 
page 81.

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 page103.

Materiality
The 2019 OZ Minerals materiality assessment  
has included evaluation of local and global 
threats and opportunities based on external 
review, benchmarking, biannual internal risk 
reviews, stakeholder consultation and external 
materiality survey. We assess sustainability 
matters based on two criteria: their importance 
to our business in terms of growth, economic 
and social impact, and their importance 
to stakeholders – including shareholders, 
community, employees, governments and 
suppliers. Material topics are discussed in 
this report and many are also covered in the 
Risk section of the Directors report, including 
climate risk, with further information on other 
sustainability topics available on the OZ Minerals 
website.

address the most important global sustainability 
challenges and can stimulate worldwide 
transformational change. OZ Minerals recognises 
that global megatrends, such as climate change, 
globalisation, digitalisation and automation 
will impact our operations and inform our 
modernisation agenda. 

OZ Minerals’ vision is to become a global copper- 
core modern mining company. Creating value 
for our key stakeholders is at the heart of our 
Strategy and shapes our global focus, products, 
operations, and how we work with stakeholders. 

Member of the International  
Copper Association Australia 
OZ Minerals is a member of the International 
Copper Association Australia, the peak body 
for the copper industry in Australia whose core 
work is sustainable development. The benefits 
of copper range widely; from renewable energy

and adaptation, many global trends driving the 
sustainable-development agenda rely on copper 
and its unique properties.

How we do things is as important as what  
we do. The OZWay defines how we work,  
our culture and behaviours.

We deliver on our sustainability aspirations at  
OZ Minerals by focusing on value creation for  
our stakeholders and we report on our value

High standards and leadership

Carrapateena ‘Bring it Home’

OZ Minerals recognises that the construction phase  
of asset development is complex and statistically poses 
risks to employees and contractors. To embed safety 
performance at Carrapateena, we launched the site 
wide ‘Bring it Home’ campaign together with our  
key contract partners. The campaign was designed  
to enhance personal and professional pride, focus  
and performance as the Carrapateena construction  
and commissioning program neared its final stages. 

Safety and wellbeing are important to us and it is the 
responsibility of all employees onsite. ‘Bring it Home’ 
was developed together with a performance coach and 
included a range of activities and initiatives aimed to 
give people a positive boost and identify and promote 
best practice. 

RISKS

Operational safety and health  

OZ Minerals is committed to high standards of the safety 
of our operations, including employees, contractors, and 
the communities in which we operate. Protecting the 
health and wellbeing of our workforce is vital.

SUSTAINABILITY REPORT

Safety culture and leadership 

We understand 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 is reasonably 
practicable.

In March 2019, OZ Minerals was saddened 
and confronted by a fatal incident involving 
an ElectraNet sub-contractor associated with 
the construction of the Carrapateena Project. 
The death of the pilot who was undertaking 
helicopter stringing has had a profound effect  
on the company, and is discussed in earlier 
sections of this report.

Our target is to achieve an injury and 
occupational disease-free workplace by ensuring 
hazards are identified and managed at 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 monitored by our leadership team.

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

The number of recordable workplace injuries  
in many of our departments has been reduced 
as a result of 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, there is a focus on compliance 
with approved processes, and we implement 
additional controls where necessary.

Safety statistics are calculated per one million 
working hours and inclusive of our Prominent 
Hill and Carrapateena Mines as well as facilities 
under OZ Minerals’ operational control. In  
2019, the total recordable injury frequency  
rate (TRIFR) per million hours worked increased 
by 4% from the previous year’s TRIFR of 7.24. 
We have set a TRIFR target of 5.50 (including 
Brazil) for 2020 which will require an improved 
performance on 2019 despite ongoing 
construction activity in Australia and Brazil.

We monitor lead indicators 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 (ICAM).

Significant incidents are those deemed to have:

 / high potential or actual serious consequences, 

or 

 / recordable incidences and disabling injuries.

We released Process Standards across all 
assets in 2019 as a component of our updated 
governance framework, including the Incident 
Reporting and Investigation Process Standard 
which sets out the process for identifying, 
elevating and reporting incidents, including 
safety-related incidents.

The Risk Management Standard, and its 
supporting guidelines, is a critical Process 
Standard and its five stakeholder pillar Risk 
Specification table supports the Incident 
Reporting and Investigation Process Standard.

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 workforce safety.

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

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

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 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.

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 during a crisis event. 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 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 our emergency preparedness.

OZ MINERALS2019 ANNUAL & SUSTAINABILITY REPORTEnvironment 
Minimising our impact and 
caring for the natural environment 
is vital for our sustainability.

Shared water use for Carrapateena 

Water is essential for our stakeholders and we appreciate 
the critical importance of sustainable water management 
in the mining and resources sector. 

In the development of the Carrapateena mine we 
focused on identifying and defining a sustainable 
water supply to meet the forecast demands of the site. 
Through 2017 and 2018 we conducted extensive water 
exploration drilling in the region, which is currently 
being further explored from an advanced exploration 
viewpoint, to confirm sustainable pumping rates of 
identified wells. 

Carrapateena has developed the Northern Wellfield so 
it uses the underground mine water inflows which are 
heavily saline and not suitable to pastoralism, to enable 
application of sustainable practices for the operation and 
to access a water source independent of pastoral station 
operators. 

OZ Minerals has worked with the South Australian 
Department of Mines (DEM) and the local pastoral 
stations to provide a treated water supply to the station 
for stock operations, creating a sustainable water source 
to support local pastoral operations. 

CLIMATE RISK

OZ Minerals recognises the physical and non-physical 
(transition) impacts of climate change may affect our 
assets, productivity, the markets in which we sell our 
products, and the communities in which we operate. 
Risks related to the physical impacts of climate change 
include acute risks resulting from increased severity of 
extreme weather events and chronic risks resulting from 
longer-term changes in climate patterns. 

Non-physical risks arise from a variety of policy, 
regulatory, legal, technology, and market responses  
to the challenges posed by climate change and the 
transition to a lower-carbon economy.

Climate change, energy use and greenhouse gas emissions

Climate change was one of the highest ranking 
topics in this year’s materiality assessment. 
Climate-related risks and the control actions 
are detailed in the risk section of the Directors’ 
Report (page 41). We are a copper-core  
modern mining company and as such provide 
a metal that is in high demand in the rapidly 
growing low carbon economy. We seek to 
conduct our activities socially, ethically and in  
an environmentally responsible manner.

During the year we developed a climate  
change statement in which we support the  
Paris Agreement objectives to limit the global 
average temperature rise to below 2 degrees 
Celsius. In this statement we commited to 
playing our part in reducing carbon emissions 
and preparing for the impacts of climate change 
along with the actions needed to achieve net-
zero carbon emissions by 2050. 

We also committed to developing a Roadmap  
for reporting of integrated climate risks and 
climate-related financial disclosures in line with 
the Task Force on Climate-related Financial 
Disclosures (TCFD) framework. 

That Roadmap has been developed and is 
aligned with and will be integrated into our 
OZWay of working. Integrating climate risk 
management and TCFD within the elements of 
how we work – our strategy and our governance 
framework which includes our risk and other 
process standards, our policies and performance 
standards - ensures implementation across the 
Company and our devolved operating assets.

As the Roadmap outlines, we aim to leverage 
and modify our Risk Management Specifications 
to comprehensively accommodate opportunities 
and threats arising from climate-related risk. 
Identifying both opportunities and threats for 
our business is key to delivering our Strategy 
in which creating value for all stakeholders is 
central. We will continue to assure our responses 
to our identified climate risks are occurring and 
we will disclose progress in our annual reporting.

OZ MINERALS2019 ANNUAL & SUSTAINABILITY REPORT 
 
 
 
82

SUSTAINABILITY REPORT

Our two major operations are connected to the 
South Australia electricity grid which is estimated 
to comprise approximately 50% renewable 
energy. In Brazil, all electricity used by our assets 
is derived from renewable hydro electricity. 

In 2019, the majority of OZ Minerals’ energy 
use occurred at the Prominent Hill mine as the 
largest operating mine in the portfolio. The  
two main areas of energy consumption were  
the processing plant (electricity) and mining 
vehicles (diesel fuel).

In 2019, Prominent Hill’s mining activities  
were underground-only having successfully 
completed the transition from the open pit.

OZ Minerals’ energy demand will continue 
to increase following the commissioning and 
production ramp up of the Carrapateena mine.

Our Australian assets have reported the 
following energy use and greenhouse gas 
emissions in line with NGERS:

 / Scope 1 Emissions (mainly onsite fuel 

combustion): 77,271 tonnes of CO2-e  
(10% decrease compared to previous year)

 / Scope 2 Emissions (grid electricity):  

176,627 tonnes of CO2-e (5% increase 
compared to previous year)

 / Total Scope 1 and Scope 2 Emissions:  

253,898 tonnes of CO2-e (stable  
compared to the previous year)

 / Diesel use is Prominent Hill’s primary source  

of Scope 1 greenhouse gas emissions.

 / OZ Minerals did not sell energy in 2019.

Water 

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

Our Australian assets, Prominent Hill and 
Carrapateena, are situated in areas with  
an average annual rainfall of less than  
200 millimeters per year and depend on 
groundwater to sustain 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.

In Australia, our water monitoring program 
involves measuring and monitoring water  
levels and quality in previously-agreed pastoral 
wells on neighbouring stations. Additionally,  
we closely monitor in-use and surrounding 
groundwater sources and report results to 
relevant stakeholders. We conduct sediment 
monitoring, including metal concentrations  
and acidity, to detect any potential changes  
in downstream surface water quality. 

Our Brazilian assets are situated in the  
Carajás Province with an annual rainfall  
of over 2,286 millimeters per year.

Our Antas asset has a Water Resources 
Management Program which aims to monitor 
and evaluate surface and groundwater.

ENERGY AND MINING  COL L ABOR AT IO N   (E M C) 

In 2018, OZ Minerals embarked on an Energy 
and Mining Collaboration (EMC) initiative with 
Adelaide University, CSIRO, the Department 
of Energy and Mining, the Rocky Mountain 
Institute, SunSHIFT and the Tonsley Innovation 
Precinct. The partnership is focused on 
investigating demand for renewables adoption in 
the mining industry in preparation for a possible 
showcase of renewable energy integration. 

The EMC facilitates collaboration between these 
organisations to investigate renewable energy 
and demand management related activities 
on a mine site, with a view to developing and 
identifying opportunities for an international 
showcase that optimises electrical and fuel 
demand and the integration of renewable 
energy systems. This will be done via the 
creation of partnerships focused on testing of 
energy and technology hypotheses to unlock 
transformational value in mining.

Air Quality

The largest air quality 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. 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. All assets monitor and manage 
emissions via an Air Quality Management Plan  
as per the Air Emissions Performance Standard.

Waste and Tailings

OZ Minerals has three active tailings facilities 
(Prominent Hill, Antas and Carrapateena). In 
2019, all assets have had inspections undertaken 
by independent and qualified geotechnical 
engineering specialists with experience in the 
design, operation and auditing of tailings dams.

Mining waste is managed onsite at Prominent 
Hill, the Antas Mine in Carajás and the new 
Carrapateena mine which is ramping up to full 
production over a 12 month period following 
first concentrate production.

Prominent Hill has one Tailings Storage Facility 
(TSF) located within the Integrated Waste 
Landform (IWL) which includes the Waste Rock 
Dump (WRD). As an IWL, the TSF is surrounded 
by a wide buttress of mine waste forming 
the Southern WRD within which a clay-lined 
perimeter embankment is constructed. The TSF 
is constructed with the downstream construction 
method. Over the reporting period, Prominent 
Hill produced  951,000 tonnes of waste rock 
and 8.8 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.

The Carrapateena Mine Stage 1 is a cross valley 
starter embankment. The initial lift (Stage 2) 
has been constructed using a downstream raise 
methodology with similar construction materials 
to that of the starter embankment. Subsequent 
raises (Stages 3 – 6) will be constructed using an 
upstream raise methodology, using consolidated 
tailings with waste rock armouring of the 
downstream faces.

The Antas facility embankment has been  
raised only once using the downstream 
construction method.

Our tailings performance standard, which  
applies across the company, 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 to groundwater. 

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.

OZ Minerals’ Australian Tailings Storage Facilities 
have been designed, constructed and operated 
in accordance with ANCOLD (Australian 
National Committee on Large Dams). In Brazil, 
quality assurance and monitoring activities are 
undertaken as normal course of business with 
bi-monthly reporting provided to the Mines 
Department (ANM).

MATERI AL RISK

Land and biodiversity

In the development of the Prominent Hill mine, 
OZ Minerals committed to the establishment 
and management of a Significant Environmental 
Benefit (SEB) offset area. The SEB is 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 objectives of the SEB offset area are 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 has been continually undertaken since 
2006 and 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 (Cth), and the Chestnut-
breasted Whiteface listed as rare under the 
National Parks and Wildlife Act 1972 (SA). 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 aimed at ensuring the 
health of the preferred habitat is maintained.

At Carrapateena, the nationally-threatened 
Plains Mouse occurs within the project area.  
A further three species listed under the  
National Parks and Wildlife Act 1972 (SA) 
have been identified as occurring within or in 
proximity to the project, including the plant 
species Frankenia Subteres (rare), the Perigrine 
Falcon (rare) and the Australian Bustard 
(vulnerable). Two environmental offset areas 
are established to support the Carrapateena 
operation – a local on-ground offset on South 
Gap Pastoral Lease for the management of 
identified Plains Mouse habitat, and a larger area 
on Witchelina Pastoral Lease to offset native 
vegetation clearance associated with establishing 
the Carrapateena project.

In the Carajas region, our teams have cultivated 
a nursery to support the maintenance of local 
biodiversity.

Rehabilitation and closure

OZ Minerals’ South Australian operations have 
documents and programs detailing closure, 
including the Supporting Works Plan and 
the Program for Environment Protection and 
Rehabilitation (PEPR). 

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 80% completed.

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 liabilities. 
Closure planning is updated throughout the 
mine’s operational life to identify and reduce 
risks and unknowns 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.

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 all 
stakeholders. We support community initiatives 
and sustainable local businesses as a part of our 
community engagement program.

Stakeholder engagement

We seek to build and maintain strong, supportive 
relationships with all stakeholders (shareholders, 
suppliers, government, communities and 
employees) in the host and local communities 
where we operate. 

Our assets have stakeholder engagement 
programs that include engagement with 
regulatory bodies, suppliers, government 
agencies, communities, land owners, land  
connected Indigenous and land connected 
peoples including local landowners within the 
sphere of influence of the operations and project 
activities. This ensures input from the local 
stakeholders 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 assets’ activities to better 
understand stakeholder values and the potential 
impacts. We provide accurate and fit for purpose 
information in a timely manner, and anticipate 
and proactively address community and 
stakeholder issues and concerns as part of the 
engagement process. 

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

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. 

Our total economic contribution for 2019 was 
$895 million and included:

 / more than $81 million in wages and benefits

 / $74.3 million in dividends to shareholders

 / $57.6 million in royalties and $64.7 million  

in taxes.

Prominent Hill and Carrapateena significantly 
contributed to local and regional economies.

Operationally, significant value is generated 
through employment directly and through 
our contracting partners, 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.

All of the 194 Carajás workforce are from  
the local community.

Report (page 111) and in the socioeconomic

Community investment and sponsorship

We have contributed to a broad range of local 
and regional programs. In addition to funding, 
our employees and contract partners provided in-
kind assistance by donating time, expertise and 
resources for community events and initiatives.

We supported locally-organised initiatives 
that provide long-term benefits to our 
host communities and are aligned with the 

communities’ wishes. Our sponsorships and 
community investment initiatives strive to 
support organisations or projects to achieve 
sustainable outcomes. We contributed 
$533,000 in sponsorship to local organisations 
and programs in 2019. Direct donations are 
complemented by in-kind contributions and  
an employee volunteering program.

EDUCATING THE NE XT  G ENE RAT IO N

OZ Minerals’ flagship corporate social 
contribution program, Educating the Next 
Generation, was launched in April 2019. 
The program was designed to support our 
local communities and enable our peoples’ 
involvement through volunteering or  
mentoring with The Smith Family and  
Clontarf Foundation over the next three years,  
in addition to our continued support of the  
Royal Flying Doctor Service.

Partnering with The Smith Family and Clontarf 
Foundation, we hope to create something with 
real impact that results in positive improvements 
in the communities we are surrounded by and 
work in. 

What makes the flagship program special is  
that it was developed in consultation with: 

 / some of our community stakeholders – 
who said the education of young people  
was important to them

 / our people – many who expressed a desire  

to make more than a financial contribution to 
a cause, preferring to volunteer skills and time, 
and even mentor through the company, and 
make a difference at the grassroots level.

While the program is being implemented in 
Adelaide, it was developed to be sustainable 
and flexible enough to be extended into multiple 
states and countries, and to complement the 
localised donations and sponsorships already 
delivered by our assets. 

Continued support of  
Royal Flying Doctors Service
OZ Minerals has been a proud and ‘major’ 
partner of the Royal Flying Doctor Service  
(RFDS) Central Operations since 2007 when  
the Prominent Hill copper-gold mine was still  
in construction. In 2019, OZ Minerals and  
RFDS renewed this longstanding partnership.

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 law.

OZ Minerals formally registered with the  
Board of Taxation’s TTC in 2019 and present  
the following information in accordance with  
the TTC:

Tax governance
The objectives of OZ Minerals tax risk 
management includes the prevention of 
disputes with tax authorities 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. 
While 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.

Australian tax-related  
contribution summary
A summary of OZ Minerals’ 2019 employee  
and tax related contributions, to State and 
Federal tax authorities, is provided in the 
performance data tables on page 101.

Local enterprise and procurement

We seek to create enduring and sustainable 
value for our host communities, states and 
territories associated with 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 not competitive. 
We also help local businesses understand our 
pre-qualification processes and procurement 
standards. Local and Indigenous and land 
connected peoples are encouraged to apply  
for positions and tender for business 
opportunities with our assets.

Our activities contributed $361.6 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.

The Kokatha Aboriginal Corporation (KAC) is 
the organisation of native title holders for the 
area encompassing a significant portion of the 
Far North of South Australia, including Roxby 
Downs and the Carrapateena Mine. In 2017, 
OZ Minerals and KAC established Kokatha 
Mining Services (KMS) a 100% KAC-owned  
business at Carrapateena that operate machinery 
including water carts and graders  as part of the 
Carrapateena development activities 

The result of the partnership was the 
establishment of a road maintenance business 
and was awarded the Carrapateena Access Road 
maintenance in December 2019. This long term 
contract will allow the KAC and Carrapateena to 
leverage future long term business opportunities 
at Carrapateena, beyond the Carrapateena 
mine and outside of the resource industry. This 
continuous improvement philosophy extends  
to the partnering model currently in place within 
OZ Minerals.

Our Brazilian assets have a high level of local 
procurement.

OZ Minerals is committed to prioritising 
sustainable local procurement and employment, 
with particular attention on the Upper Spencer 
Gulf, an Outback Community. Since 2016,  
OZ Minerals has partnered with Global 
Maintenance Upper Spencer Gulf (GMUSG) 
to drive local content activities, facilitating 
connection of local businesses to the 
Carrapateena supply chain. We have actively 
facilitated lead contractor introductions to local 
suppliers and businesses, which has resulted in  
a number of Indigenous and local contractors 
and suppliers being engaged onsite. 

Carrapateena’s Australian Industry Participation 
Plan requires relationships to be fostered with 
key regional stakeholders, providing business 
and employment opportunities directly, and 
through our major contractors who are critical 
stakeholders for the project.

Voice Treaty Truth
We recognise Aboriginal and Torres Strait  
Islander Peoples as the first people of Australia 
and the importance to all of us for their voice 
to be heard. We support efforts being made to 
achieve this next step in National Recognition.

In support of the principles of Voice, Treaty and 
Truth, we undertake to continue working with 
our traditional owner partners in the spirit of 
shared value and mutual obligation to create 
sustainable benefits by leveraging, developing 
and building on our shared aspirations, while 
protecting and respecting country and culture.

We recognise and respect the unbroken cultural 
connection and cultural authority of Aboriginal 
and Torres Strait Islander Peoples in Australia. 

A value creation and partnering approach 
focused on building mutual respect and 
knowledge to recognize 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 people dedicated to regular 
liaison with Indigenous communities.

The requirements regarding engagement with 
Indigenous communities are set out in the  
Land-Connected and 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 and 
land-connected people is based on principles  
of equality, transparency and mutual benefit. 
It respects and protects the rights of Indigenous 
People and is in line with the values of Free Prior 
and Informed Consent (FPIC).

WEST MUSGRAV E RANGE R CO L LAB O RAT I ON

Between September and December 2019,  
the Ngaanyatjarra Council’s Blackstone Ranger 
team undertook a regional survey for Tjakura 
(Great Desert Skink-Egernia kintorei) in the areas 
surrounding the West Musgrave Project. Tjakura 
is listed under the Commonwealth Environment 
and Biodiversity Conservation Act 1999 
(Comm EPBC Act) and the Western Australian 
Biodiversity and Conservation Act 2016 (WA  
BC Act) as Vulnerable. The work was undertaken 
to identify whether a future copper and nickel 
project at West Musgrave may present any 
impact to this species.

This engagement represents one of the most 
significant engagements of the Blackstone 
Ngaanyatjarra Ranger team by stakeholders 
external to the Ngaanyatjarra Lands. This type 
of work leverages the Ngaanyatjarra Traditional 
Owners’ deep knowledge of the regional 
landscape, and the biodiversity within it. This  
is seen by local people to represent valuable 
work for the preservation and documentation  
of their environments.

Through this, the Blackstone Ngaanyatjarra 
Ranger team identified a further seven regional 
populations of Tjakura, representing a nationally 
important find given that the species was 
considered to be rare. These finds also confirm  
a potential future project presents minimal risk  
to the viability and persistence of this species.

Human rights

Our internal governance is guided by 
international guidelines, including 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 compliance and ethical business. Asset 
induction training raises awareness of human 
rights responsibilities with senior management, 
employees, contractors (particularly security 

personnel), 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 minimise the risk of human 
rights violations in our operations or in our 
supply chain.

Modern Slavery Act
We seek to address the risk of modern slavery 
in our operations and supply chains and comply 
with the Modern Slavery Act 2018 (Cth). 
Currently, we are working with our supply  
chains to meet the new reporting obligations. 

MATERI AL RISK

HUMAN RIG HT S AN D E THIC S 

OZ Minerals’ activities are exposed to human 
rights, ethics, and social well-being expectations.  
Our operations and supply chain are subject 
to human rights, ethics, and employment 
conditions, which may vary from time to time.

The company recognises the potential for human 
rights exposures and risks in all jurisdictions and 
is committed to working broadly to promote 
respect through stakeholder engagement, 
collaboration, advocacy, and contribution to 
public policy development. 

Anti-bribery and corruption

We carried out an internal audit of our  
Anti-Bribery and Corruption Standard and 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 our 
Brazilian assets. The primary purpose of the 
internal audit was to identify the bribery and 
corruption compliance risks we face, how 
these risks are currently managed and what 
improvements could be made to the  
governance and compliance framework.

Online training was provided to all our 
employees. 

The OZ Minerals public and internal facing  
Anti-Bribery and Corruption material was 
updated in 2019. 

The OZ Minerals public-facing ‘Whistleblower’ 
material has been released as ‘Speak Up’ 
following updates in line with the Australian 
Whistleblower Legislation introduced in 2019.

CentroGold apprentices undergo  
training at Antas Norte

OZ Minerals has a strong commitment to education 
and training for host communities. In June 2019, young 
apprentices from our CentroGold project travelled to the 
Antas mine, 1,600 km away, to undertake three months 
of onsite workplace training. The eight apprentices 
participated in onsite training designed to provide an 
authentic experience and support them in understanding 
the company’s culture, standards and safety policies. 
The training blended theoretical teachings and practical 
application of that knowledge into activities to be 
developed in the project located in Maranhão. 

“Our job was to bring qualifications training to these 
young people living in the Centro Novo (MA) community, 
home to the CentroGold project, and to provide 
experience in the mining environment. As such we hope 
they can take quality information to the community they 
live in,” said Polyanne Lima, Human Resources Supervisor.

Health and wellbeing programs

Our people’s health and wellbeing are important 
to us. People with a strong sense of wellbeing 
are more engaged at work and are better for 
their communities and families. In 2019, we 
implemented a number of programs to promote 
and support physical, mental, social and 
emotional health and wellbeing. We also actively 
promoted flexible working arrangements for 
our people, allowing them to work in ways that 
support their commitments outside of work. 

Our fitness-for-work program includes a wide 
range of activities and education in fatigue 
management, employee assistance programs, 
role-based assessments, fitness, and drug and 
alcohol programs. We provide our people with 
the necessary education and information to  
self-manage their fitness-for-work. 

We value the continued development of an 
inclusive culture where people can openly talk 
about mental health. In 2019, we implemented 
several preventative programs to support 
mental wellbeing. This included incorporating 
mindfulness through the Smiling Mind Program 
in the Adelaide Office. The team at Carrapateena 

worked with an external partner to deliver 
training that raised awareness of mental health.
Both Prominent Hill and Carrapateena assets 
have developed mental health initiatives in order 
to raise awareness of mental health and suicide 
prevention. Over 300 people have participated 
in the Carrapateena mental health awareness 
sessions with 50 personnel completing mental 
health first aid training.

OZ Minerals continues to 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 provides 
access to a network of accredited counsellors 
and psychologists that can support with both 
work and personal issues. 

Throughout the year, OZ Minerals provided  
free medical check-ups, skin cancer checks,  
flu-vaccinations and health education classes. 
Our people also have access to corporate  
health plans and income protection.

Business ethics and ethical conduct training

The Code of Conduct is our highest order 
of corporate governance and outlines the 
importance of – and our commitment to – 
maintaining an open working environment 
so our employees and contractors can report 
instances of unethical, unlawful or undesirable 
conduct without fear of intimidation or reprisal.

We have appointed STOPline as the disclosure 
line to report unacceptable conduct 
confidentially and anonymously under the  
‘Speak Up’ (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. 

Our interactive online induction program further 
reinforces our Code of Conduct, policies and 
performance standards.

Diversity and inclusion

We are committed to developing an inclusive 
culture where people are treated fairly and 
respectfully, where they feel valued and have 
a sense of belonging. This includes creating 
a psychologically safe work environment that 
empowers each person to contribute and  
express their ideas. 

We focus on, and continue to support, diversity 
for under-represented groups and provide equal 
access and opportunity for all people regardless 
of age, gender, race, national or ethnic origin, 
cultural background, experience, social group, 
marital status, religion, language, political beliefs, 
sexual orientation or physical ability. Several 
strategies are in place to increase the level of 
inclusion, demographic diversity and diversity  
of thought. 

The participation of women, Indigenous  
peoples and a multi-generational workforce 
continues to be measured. 

Women make up 21% of the workforce directly 
employed by OZ Minerals, with the Board 
and senior leadership having >30% female 
representation. There are approximately 193 
Aboriginal people working at Prominent Hill and 
Carrapateena (as employees and contractors) – 
representing 6% of our Australian workforce, 
one of the highest representations of Aboriginal 
people within Australian mining workforces.

Equal remuneration is offered for all our 
employees, reflective of the type of job,  
years of experience and the period for which 
employees have held their position. This 
continues to be annually reviewed to provide 
assurance that our employees’ remuneration 
remains equitable and in line with market trends.

(a) Scope 1 refers to emissions produced directly by operations, primarily resulting from combustion of various fuels and includes CO2-equivalent values for greenhouse gases such as CH4, N20 and SF6.
(b) Scope 2 refers to indirect emissions resulting from the import of electricity from external parties; commonly the electricity grid.

Not applicable

Criteria Used as the Basis of Reporting 
The criteria used in relation to the Sustainability 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), Prominent Hill and Antas mine sites;

 / walkthroughs of the Selected Sustainability Information to source documentation;

relevant underlying sources on a sample basis; 

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

 / reviewing the Sustainability 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 2019, 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

MINERAL RESOURCES & 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. Significant increases have been 
made due to changes in OZ Minerals’ portfolio throughout 2019, with the change in reporting for 
the Carrapateena Mineral Resources and the addition of several new estimates as a result of the 
integration of the Brazilian assets. 

OZ Minerals’ Group Mineral Resources are estimated at 9.3 million tonnes of copper and 15 million 
ounces of gold (1.6Bt @ 0.6% Cu and 0.2g/t Au) up from 4.8 million tonnes of copper and  
8.9 million ounces of gold in 2018. Group Ore Reserves are estimated at 2.1 million tonnes of  
copper and 4.3 million ounces of gold (175Mt @ 1.2% Cu and 0.8g/t Au) in comparison to  
2.1 million tonnes of copper and 3.1 million ounces of gold in 2018.

The information in this section is drawn from the following releases:

Summary of significant changes since 2018

Mining depletion of estimated underground Mineral Resources at Prominent Hill were offset through 
growth as a result of diamond drilling in the 30 June 2019 update. Similarly, depletion of the Ore 
Reserves through mining was mostly offset by additional drilling and subsequent design review.

Carrapateena Mineral Resources saw a significant increase primarily due to change of the upper half 
of the mineralisation assumed to be mineable using a block cave mining method. The Ore Reserves 
saw a minor increase in tonnes and metal, mainly due to refined mine design. 

Antas North has undergone a full year of mining depletion. 

There have been no changes to the Mineral Resource estimates of Fremantle Doctor or Chega Tudo 
throughout 2019.

The joint venture with Cassini Resources continued to progress with OZ Minerals earning 70% 
ownership of the project and releasing an updated Mineral Resource estimate for Nebo-Babel based 
on additional drilling. This saw a large amount of Inferred material increase in confidence to Indicated 
and a reduction in overall tonnes, primarily due to the estimate being confined with a pit shell.

Antas North, Pedra Branca and CentroGold are all now included in the OZ Minerals’ Group Mineral 
Resource and Ore Reserve estimate following integration and internal review.

A recent review of the 2012 stated Antas South Mineral Resource estimate has concluded that there 
are no longer reasonable prospects of economic extraction and the estimate has been withdrawn.

Note:  OZ Minerals acquired the Pantera option when it acquired Avanco Resources and its Brazilian assets in August 2018; see Avanco’s ASX Announcement “Maiden Pantera MRE pushes Avanco’s 

Carajás Resource Base Beyond 1 Mt of Contained Copper” released on 19 March 2018. This estimate is subject to further drilling and review. OZ Minerals’ interest in the tenement is subject to  
the production of a revised Resource by 2021 and OZ Minerals’ election to either purchase the tenement or return the title to Vale at that time.

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.

Mining and processing underground ore containing copper, gold and silver. The Carrapateena 
mine which is located in the Gawler Craton of South Australia was constructed during the year 
and produced first saleable concentrate in December 2019.

Mining and processing open pit ore containing copper and gold from the Antas mine and 
developing the Pedra Branca Mine in the Carajás Hub in Brazil. The Carajás hub generates 
revenue from the sale of concentrate containing copper and gold to customers in Europe and 
Asia. The Company is undertaking exploration at Pantera and other projects. 

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, 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 including CentroGold.

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 generates sales revenue primarily from the transfer of concentrate to buyers 
and in some cases, based on the commercial terms of the contract, delivering it to customers. 
The performance obligation to transfer concentrate and delivery arises as and when a shipment is 
agreed with customers against ongoing short and long-term supply contracts. 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 a deduction from the value of metal contained within the concentrate and accordingly are 
recognised as a deduction from revenue.

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, typically three months. 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 recorded in revenue and 
generally offsets movement resulting from provisional pricing.

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. 

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.

RECOVERABILITY OF DEFERRED TAX ASSETS 

The Consolidated Entity is subject to income taxes in Australia and of the 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 probable of being 
accepted by the relevant tax authorities. 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.

changed its estimate of the probability that future taxable profits will be available against which 
unused tax losses can be utilised and additional restricted tax losses of $17.8 million tax effected 
(2018: $7.4 million) were recognised on the balance sheet. Australian restricted tax losses of  
$152.9 million tax effected (31 December 2018: $170.7 million) remain unrecognised at  
31 December 2019. Capital tax losses of $595.0 million tax effected (2018: $595.0 million tax

OZ MINERALS2019 ANNUAL & SUSTAINABILITY REPORT124

FINANCIAL REPORT

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 resolved on 18 February 2020 to pay 
a fully-franked dividend of 15 cents per share. The record date for entitlement to this dividend is 
12 March 2020. The financial impact of the dividend amounting to $48.6 million has not been 
recognised in the Consolidated Financial Statements for the year ended 31 December 2019 and  
will be recognised in subsequent consolidated financial statements.

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 model 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 ore stockpiles and concentrates resulted in an adjustment to increase 
the net value of inventory by $28.3 million in 2019 (2018: $25.0 million). The increase is mainly a 
reversal of previous net realisable value write downs.

Recognition and measurement of inventories
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.

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.

(b)  Acquisition through business combinations and associated foreign currency exchange differences have been restated upon completion of purchase price allocations at fair value and exploration 

assets of $75.0 million have been recognised as at acquisition date. See Note 8 for further details.

Depreciation was $91.6 million for the year compared to $148.3 million in 2018. Depreciation expense decreased primarily due to the 
closure of the Prominent Hill open pit in the first quarter of 2018 which was partly offset by the depreciation charges associated with  
the addition of the Antas open pit mine. 

The mineral rights balance at 31 December 2019 of $479.6 million is attributable to the Carajás province ($147.6 million) and the  
Gurupi province ($332.0 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.

As at the reporting date, OZ Minerals had not reached the specified performance milestones to recognise a liability on the balance  
sheet for these further payments.

OZ MINERALS2019 ANNUAL & SUSTAINABILITY REPORT128

FINANCIAL REPORT

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 that 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 occur 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. 

Mineral rights comprise identifiable mineral resources and ore reserves which are acquired as part 
of a business combination and are recognised at fair value at date of acquisition. Mineral rights are 
subsequently reclassified as mine property and development once mine development commences.

Mine property and development assets include costs transferred from exploration and evaluation 
assets and mineral rights once technical feasibility and commercial viability of an area of interest are 
demonstrated. After transfer, all subsequent expenditures to develop the mine to the production 
phase and 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 
the development of the asset prior to it 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, rehabilitation, restoration and 
dismantling of assets after its use is included in the cost of the respective asset if the recognition 
criteria for a provision is met including revision to the expected cost.

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 the 
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.

MINERAL RESOURCE AND ORE RESERVE 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; 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  
units of ore available for extraction over which property, plant and equipment is depreciated.

OZ MINERALS129

RECOVERABILITY OF ASSETS 

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, Carajas and Gurupi 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.

When the Group reviewed impairment indicators, consideration was also 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 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.

8. Exploration assets

CARRYING VALUE OF CAPITALISED EXPLORATION EXPENDITURE

The accounting policy for exploration and evaluation expenditure requires judgement to determine whether future 
economic benefits are likely from either future exploitation or sale, or whether activities have not reached a stage that 
permits a reasonable assessment of the existence of reserves. In the event future economic benefits are unlikely or a 
reasonable assessment of the existence or otherwise of economic reserves is not possible, an impairment test may be 
required which may result in an adjustment to the carrying value of capitalised exploration expenditure. 

The ultimate recoupment of costs capitalised for exploration and evaluation phases is dependent on successful 
development and commercial exploitation or sale of the respective area of interest.

Acquisition through business combinations and associated foreign currency exchange differences have been restated upon completion of 
purchase price allocations at fair value and exploration assets of $75.0 million have been recognised as at acquisition date. Exploration assets  
of $6.9 million were included in other assets in prior year.

Recognition and measurement of exploration expenditure 
Exploration and evaluation expenditure is recognised in the Income Statement as incurred, unless it is 
expected to be recouped through successful development and exploitation of the area of interest, or 
alternatively by its sale, in which case it is recognised as an asset on an area of interest basis, or the 
exploration asset is acquired in a business combination. 

Exploration and evaluation assets are classified as tangible according to the nature of the assets. 
Exploration and evaluation assets are not depreciated and are assessed for impairment when facts 
and circumstances suggest that the carrying amount exceeds the recoverable amount. 

For the purposes of impairment testing, exploration and evaluation assets are allocated to cash-
generating units to which the exploration activity relates. A Cash Generating Unit (CGU) is not  
larger than the area of interest. Once the technical feasibility and commercial viability of the 
extraction of mineral reserves in an area of interest are demonstrated, exploration and evaluation 
assets attributable to that area of interest are first tested for impairment and then reclassified to  
mine property and development assets within property, plant and equipment.

From time to time the Consolidated Entity enters into arrangements which enable it to secure the 
opportunity to explore and potentially earn the right to mineralisation if discovered on underlying 
exploration tenements held by other entities (earn-in arrangements). Under the agreements,  
OZ Minerals does not assume any liabilities or hold any rights to other assets that the holder of 
the tenement may possess. Expenditure is accounted for under OZ Minerals accounting policy for 
exploration and evaluation expenditure.

The right-of-use (ROU) assets include office space, mining equipment leases contained in mining 
service contracts, and powerline infrastructure.

OZ MINERALS131

Recognition and measurement of right-of-use assets
AASB 16 eliminates the distinction between operating and finance leases and brings all leases  
(other than short term and low value leases) onto the balance sheet. As a lessee, the Consolidated 
Entity 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. Short term and low value leases are 
expensed in the consolidated statement of comprehensive income on a straight-line basis over the  
life of the lease.  

The Group recognises a right-of-use (ROU) asset and a lease liability at the lease commencement 
date. The right-of-use asset is initially measured at cost (present value of the lease liability, deemed 
cost of acquiring the asset and restoration or make good cost), and subsequently at cost less any 
accumulated depreciation, impairment losses and adjustments for remeasurement of the lease 
liability. The ROU assets are depreciated over the life of the lease which generally ranges between 
1 to 20 years. The lease liability is initially measured at the present value of the lease payments 
expected to be paid over the lease term, discounted using the interest rate implicit in the lease or, 
if that rate cannot be readily determined, the  entity’s incremental borrowing rate. The lease liability 
is subsequently increased by the interest cost on the lease liability and decreased by lease payments 
made. The lease liability is further remeasured if the estimated future lease payments change as a 
result of index or rate changes, residual value guarantees or the likelihood of exercising purchase, 
extension or termination options. 

EXTENSION AND RENEWAL OF LEASE 

The Consolidated Entity has applied judgement to determine the lease term for lease contracts that include renewal 
options. The assessment of whether the Group is reasonably certain to exercise such options impacts the lease term, 
which affects the measurement of lease liabilities and right-of-use assets recognised.

Where practicable, the Group seeks to include extension options in new leases to provide operational flexibility. 
The extension options held are exercisable only by the Group and not by the lessors. The Group assesses at lease 
commencement date whether it is reasonably certain to exercise the extension options. The Group also reassesses 
whether it is reasonably certain to exercise the options if there is a significant event or significant changes in 
circumstances within its control. 

The Group has estimated that the potential future lease payments, should it exercise the available 
extension options, would result in an increase in the lease liability amount of $16.9 million.

10. Provisions

MINE REHABILITATION, RESTORATION & DISMANTLING OBLIGATIONS 

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.

OZ MINERALS2019 ANNUAL & SUSTAINABILITY REPORT132

FINANCIAL REPORT

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.

11. Commitments

The Consolidated Entity has entered into an agreement with ElectraNet for the transmission of  
power and the build, own, operation and maintenance of electricity transmission infrastructure  
to Carrapateena and Prominent Hill. The total future commitment for these arrangements is  
$538.9 million. Once electricity infrastructure construction is completed it is expected that a right  
of use asset and lease liability will be recognised.

In addition, the Consolidated Entity has entered into various contracts with suppliers for the 
construction of the Carrapateena and Carajás mines and sustaining mine development at the 
Prominent Hill, Carrapateena and Carajás mines. The total capital expenditure commitment in relation 
to these contracts as at 31 December 2019 was $707.3 million (2018: $303.0 million), of which 
$207.5 million is expected to be incurred in 2020.

set on TSR and All-In Sustaining Costs, weighted at 70% and 30% respectively.

Performance rights granted under the PRPs or LTIPs do not include dividends or voting rights. All performance rights under current 
performance rights plans are automatically exercised upon vesting which is dependent upon meeting both the service condition and 
the performance condition. When issued, the shares on vesting of performance rights rank equally in all respects with previously issued, 
fully paid ordinary shares. 

The fair value of services received in return for share-based payments granted during the year is based on the fair value of the 
performance rights granted, measured using a binomial approximation option valuation model and Monte-Carlo simulation valuation 
model for performance rights plans and long-term incentive plans respectively. The models use the following inputs:

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 KPI, 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.

FINANCIAL REPORT

Risk management

14. Financial risk management

OZ Minerals’ Group Treasury Function (Group Treasury) evaluates and manages financial risks for  
the Group 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 commodity 
markets, financial markets, counterparty credit risk 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

 / counterparty 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)

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

Investments in equity securities

Trade receivables
Derivative financial instruments

Carried at amortised cost

Cash and cash equivalents(a)
Other receivables(a)
Trade payables(a)
Other payables(a)
Lease liabilities

(a) The carrying value of each of these items approximates fair value.

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 1. 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 90 days.

Other receivables are recognised initially at fair value and subsequently measured at amortised cost 
using the effective interest method.

OZ MINERALS137

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 or part of it expires 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 is recognised for any expected credit 
loss for the lifetime of the financial asset, accounted for at amortised cost or fair value through other 
comprehensive income. Credit losses are measured on the present value of all cash shortfalls between 
the cash flows due to the entity in accordance with the contract and the expected cash flows. 

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. Lease liabilities are 
recognised at net present value and reduced by the actual payment made (refer Note 9).

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.

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 reversal 
is recognised in the income statement. 

Derivative financial instruments
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 unless the 
derivative is designated as a hedging instrument in a hedge relationship.

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 a derivative financial instrument, which has been designated in a 
cashflow hedge relationship, will be recognised in other comprehensive income to the extent the 
hedging relationship remains effective and the underlying hedge item has not been recognised in 
the income statement, or will be 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 will be 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.

During the 2019 financial year, OZ Minerals aimed to realise the forward copper price at the time of 
shipment of concentrates to customers, that matched the quotation period of the underlying sale.

Gold derivative contracts

OZ Minerals has entered into gold forward contracts to fix the price in AUD of around 38% of 
forecast sales (gold oz.) in the period from 2020 to 2021 and around 38% of the gold contained  
in stockpiles at 31 December 2019.

OZ MINERALS2019 ANNUAL & SUSTAINABILITY REPORT138

FINANCIAL REPORT

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 $52.0 million was recognised in other comprehensive loss and $23.9 million was transferred 
out of Cash flow hedge reserve to profit and loss during 2019. At 31 December 2019, contracts 
for 162,450 ounces of gold were outstanding with an average strike price of $1,753 per ounce, as 
reflected in the chart below:

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

During the financial year, the Consolidated Entity managed its exposure to copper price volatility 
between revenue recognition and contractual quotation pricing by entering into copper derivative 
contracts at the time of concentrate sales. The copper derivative contracts  fix the forward price at 
the time of sale. These derivative contracts are designated as hedges and are recognised within the 
income statement as part of revenue. 

Commodity price sensitivity analysis

The analysis below reflects the impact of movements in gold prices. Variations in silver prices have 
been deemed immaterial for the purpose of this analysis. 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 a $1.2 million  
after tax impact in the income statement on the trade receivables balance of $83.1 million (2018: 
$70.9 million) and has a $35.5 million after tax impact on the derivative financial liability of  
$70.6 million (2018: $15.6 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 (primarily USD and Brazilian Real).

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 and considers 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.

All exchange differences that arise on translating results and the financial position of all entities 
within the Consolidated Entity that have a functional currency different from the presentation 
currency are recognised as a separate component of equity in the foreign currency translation reserve. 
When a foreign operation is sold a proportionate share of such exchange differences is recognised in 
the Income Statement as part of the gain or loss on sale where applicable.

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 their currency 
risk exposure at the reporting date are disclosed below.

At reporting date, if the foreign currency exchange rates strengthened/(weakened) against the 
functional currency by 5% and all other variables were held constant, the Consolidated Entity’s after 
tax profit would have changed by $3.8 million and other comprehensive income would have changed 
by $2.9 million (2018: $0.5 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 5% change in the foreign currency rate.

OZ MINERALS2019 ANNUAL & SUSTAINABILITY REPORT140

FINANCIAL REPORT

Interest rate risk management and sensitivity analysis
The Consolidated Entity did not have any debt as at 31 December 2019 and therefore is not exposed 
to interest rate risk on borrowings. However, loans and borrowings include lease liabilities recognised 
under AASB 16 which are subject to discounting. 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, investment of cash and derivative financial instruments.

The credit risk on cash and cash equivalents and derivative financial instruments is managed by 
restricting financial transactions to relationship banks which have Board approved exposure limits  
and a minimum credit rating assigned by an internationally recognised credit rating agency. 

Credit risk in trade receivables is managed by restricting trade credit to Board approved exposure 
limits with customers that have a minimum credit rating or trade credit that is secured by a letter  
of credit from a bank with an acceptable credit rating.

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% of the estimated value of each sale either promptly after vessel loading or upon the  
vessel arriving at the discharge port.

Three major customers (2018: two) who individually accounted for more than 10% of total revenue 
contributed approximately 81% of total revenue (2018: 64%). These customers also represent 94% 
of the trade receivables balance as at 31 December 2019 (2018: 88%). There were no instances 
of customer default during 2019 and there are no significant receivables which are past due at the 
reporting date.

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, the maturity profiles of term deposits and maintaining committed available bank credit 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 
derivative financial instruments, whereas for other obligations the respective undiscounted cash flows 
for the upcoming financial years are presented.

15. Contingencies

CONTINGENCIES  

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 and 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 financial 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 $369.2 million as at 31 December 
2019 (31 December 2018: $209.1 million) and are issued under bilateral bank facilities that are rolled 
forward each twelve months.

Deeds of indemnity
The Consolidated Entity has granted indemnities under deeds of indemnity with current and former 
executive and non-executive directors, current and former officers, the former General Counsel–
Special Projects, former Group Treasurers 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 Consolidated Entity 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 2019.

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

16. Subsidiary acquisition

OZ Minerals acquired 100% of Avanco Resources Limited’s (Avanco) shares in 2018 and initially 
recognised all the acquired assets and liabilities of Avanco at their fair values or provisional fair values 
as disclosed in the 31 December 2018 annual report. Subsequently the Company conducted detailed 
valuations of the assets and liabilities acquired as at the acquisition date which resulted in a change 
of classification of exploration assets and property, plant and equipment. The fair value of net assets 
acquired remains unchanged.

18. 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.

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 high availability corporate 
bonds with terms to maturity and currency that match, as closely as possible, the estimated future 
cash outflows.

21. Related party transactions

A number of KMP, or their related parties, may 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.

23. New accounting standards

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 2018 except for AASB 16 Leases as described below.

AASB 16 Leases
The Consolidated Entity has applied AASB 16 from 1 January 2019. It has adopted the modified 
retrospective approach, under which the cumulative effect of the initial application is recognised in 
retained earnings at 1 January 2019 without restatement of comparative information for 2018.

AASB 16 eliminates the distinction between operating and finance leases and brings all leases (other 
than short term and low value leases) onto the balance sheet. As a lessee, the Consolidated Entity 
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.

An assessment is made, at inception or when contract terms are changed, to determine whether  
the contract is or contains a lease. A contract is, or contains, a lease if the contract conveys a right  
to control the use of an identified asset for a period of time in exchange for consideration.

The Consolidated Entity determines the consideration attributable to the lease or a lease  
component within a contract on the basis of the standalone price of the assets for which a right  
of use is conveyed. 

The Consolidated Entity has elected to recognise lease payments associated with low value assets  
and short term leases as an expense on a straight-line basis over the lease term.

The Group presents lease liabilities in ‘Loans and borrowings’ in the consolidated balance sheet.

Transition
The Consolidated Entity has leases and embedded leases within service contracts which typically 
include the option to renew the lease for an additional period after the end of the non-cancellable 
period. Some leases also provide for additional payments based on changes in local price indices.

At transition, all lease liabilities were measured at the present value of the remaining lease payments, 
discounted using the entity’s incremental borrowing rate at 1 January 2019. The right-of-use assets 
are measured at their carrying amount as if AASB 16 had applied since the commencement date and 
the incremental borrowing rate at 1 January 2019 was used.

The Group applied the following principles when applying AASB 16:

 / Applied an exemption not to recognise right-of-use assets and liabilities for leases with remaining 

lease terms less than 12 months as at 1 January 2019.

 / Excluded initial direct costs from measuring the right-of-use asset at the date of initial application.

 / Used past experience when determining the lease term where the contract contained options to 

extend or terminate the lease.

 / The Group applied a consistent incremental borrowing rate to a portfolio of leases with similar 

characteristics.

 / The Group relied on the onerous contract assessment completed prior to transition as an  

alternative to impairment testing of the ROU assets.

Impacts on financial statements
a. Impacts on transition

On transition to AASB 16, the Consolidated Entity recognised right-of-use assets, and lease liabilities, 
reporting the net difference within retained earnings. The impact on transition is summarised below:

When measuring lease liabilities on transition, the Group discounted lease payments using an  
average rate of 3.5% at 1 January 2019.

The leases liability on transition to AASB 16 includes arrangements identified within mining 
services supply contracts ($97.5 million) and other agreements ($7.7 million). No operating lease 
commitments were disclosed at 31 December 2018.

b. Impacts for the period

As a result of initially applying AASB 16 in relation to the leases previously accounted for as operating 
leases, the Group recognised $93.8 million of right-of-use assets and $101.0 million of lease liabilities 
as at 31 December 2019.

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 2019 

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 2019;

 / 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 or 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 Consolidated Entity 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 (including Independence Standards) (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 finalisation for the purchase of Avanco Resources Limited and  

its controlled entities; 

 / Valuation of Low Grade Gold Ore Stockpiles; and

 / Adoption of the new accounting standard AASB 16 Leases.

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.

FINANCIAL REPORT

Acquisition accounting finalisation for the purchase of Avanco Resources Limited  
and its controlled entities ($467.4 million)

The key audit matter

How the matter was addressed in our audit

During 2018, the Group purchased Avanco 
Resources Limited and its controlled entities 
(Avanco). The provisional acquisition accounting 
for Avanco was finalised in 2019.

The finalisation of acquisition accounting for the 
purchase of Avanco is a key audit matter due to:

 / The pervasive impact of the acquisition on 
the Financial Report. Consequently it was a 
significant part of our audit.

 / The level of judgement and audit effort we 

applied in auditing the Group’s determination 
of the fair value of acquired mineral rights  
for each project and exploration assets,  
based on available information. The Group 
engaged an external valuation expert to 
determine the fair value of the mineral rights 
and exploration assets.

 / The complexity in accounting for deferred tax 
consequences related to mineral rights arising 
on acquisition. 

Our procedures included:

 / We evaluated the acquisition accounting 

against accounting standard requirements  
and industry practice.

 / We challenged the significant judgements 
made by the Group in determining the fair 
value of acquired mineral rights and exploration 
assets. This included comparing the value of 
mineral rights recognised for each project 
and exploration assets to the external expert’s 
valuation report. We cross checked the value 
of mineral rights and exploration assets in the 
external report to published reports by brokers 
and analysts.  

 / We assessed the scope, competence and 

objectivity of the Group’s external valuation 
expert engaged to determine the fair values of 
the mineral rights and exploration assets. 

 / We evaluated the Group’s measurement 

of the deferred tax liability arising from the 
recognition of mineral rights against applicable

Valuation of Low Grade Gold Ore Stockpiles ($224.8 million)
Refer to Note 5 to the Financial Report

The key audit matter

How the matter was addressed in our audit

Significant judgment is exercised by the Group  
in their determination of the value of low  
grade gold ore. The low grade gold ore will 
be combined with copper ore to produce 
concentrate. The valuation of low grade gold  
ore stockpiles is a key audit matter due to:

 / The significant judgment required by us to 

assess the key assumptions used in the Group’s  
valuation model.

 / The size of low grade gold ore stockpiles as a 

proportion of total assets (5.9%). 

The Group’s valuation model estimates future 
proceeds 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. 

Our procedures included:

 / We tested the Group’s key controls relevant to:

 – The valuation of low grade gold ore 

stockpiles, including board review and 
approval of key assumptions used in the 
Group’s model such as commodity prices  
and foreign exchange rates; and

 – The process for recording and monitoring 

volumes and grades of stockpiled low grade  
gold ore, such as the 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 
the accounting standards.

 / We compared the results of the Group’s 

external quantity surveyors to the volume of  
low grade gold ore stockpiles recorded in the 
Group’s model at 31 December 2019. 

OZ MINERALS155

We focused on the significant forward-looking 
assumptions the Group applied in their valuation 
model, including: 

 / Future metal production levels (ore blend rates), 
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 planned to be processed and 
sold. 

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

Assumptions are forward looking and / or not 
based on observable data and are therefore  
inherently judgmental to audit.

 / We compared grades of stockpiled low grade 
gold ore recorded in the model to the grades 
recorded in previous periods and to the 
Group’s internal surveyor’s 31 December 2019 
measurement of grades.  

 / We assessed the scope, competence and 

objectivity of the Group’s internal surveyors,  
to grade the low grade gold ore stockpiles.

 / We challenged the Group’s key assumptions 
used in the model to determine the value  
of low grade gold ore stockpiles by:

 – Comparing future processing costs of low 

grade gold ore to historical actual processing 
costs.

 – Assessing future selling costs against current 
costs, by comparing to a sample of existing 
customer sales contracts.

 – Assessing future commodity prices and 

foreign exchange rates applied by the Group 
against published analyst and broker data. 

 – Comparing forecast production of low grade 
gold ore to be processed to publicly disclosed  
mill capacity.

Adoption of the new accounting standard AASB 16 Leases (Right-of-use asset  
($176.1 million), lease liability ($183.9 million) , depreciation and amortisation  
and interest expense ($24.9 million) and adjustment to opening retained earnings 
($6.1 million)
Refer to Note 23 to the Financial Report

The key audit matter

How the matter was addressed in our audit

Adoption of the new accounting standard AASB 
16 Leases (“AASB 16”) is inherently complex, 
where specific lease features drive different 
accounting outcomes, increasing the need for 
interpretation and judgement. 

This is a key audit matter for us due to the 
following:

 / The Group was required to interpret these new 

and complex accounting requirements and 
implement new accounting policies for the first 
time in the year.  Applying a new standard to 
existing business practices is more challenging 
with little precedent. 

 / The size of the impact of right-of-use 

assets, lease liabilities and depreciation and 
amortisation on the financial statements.

The most significant area of judgement we 
focused on was leases embedded within supply 
contracts.  The Group enters into multiple service 
and supply contracts with various features, 
which increases the possibility of not identifying 
embedded leases. 

We involved our senior audit team members in 
assessing this judgement.

Our procedures included:

 / We considered the appropriateness of the 

Group’s new accounting policies against the 
requirements of the accounting standard  
and our understanding of the business and 
industry practice.

 / We obtained an understanding of the Group’s 

new processes used to calculate the lease 
liability, right-of-use asset, depreciation and 
amortisation, interest expense, and retained 
earnings adjustment. 

 / We assessed the completeness of the Group’s 
leases, taking into consideration the selected 
transition approach and practical expedients 
applied on adoption by:

 – Inspecting a sample of lease agreements 

entered into by the Group and comparing 
these to the listing of leases; 

 – Inspecting a sample of non-lease agreements 
including service and supply contracts for the 
existence of embedded leases;

 – Inspecting relevant expense accounts for 

routine payments during the year to identify 
the existence of leases not included in the 
Group’s listing of leases.

FINANCIAL REPORT

 / We compared the Group’s inputs to the 

AASB 16 lease calculation model, such as, 
key dates, fixed and variable rent payments, 
renewal options, incentives, and make good 
obligations, for consistency to the relevant 
terms of underlying source documents, 
including signed lease agreements. 

 / We considered the sensitivity of the Group’s 
AASB 16 lease calculation model by varying 
the incremental borrowing rate, within a 
reasonably possible range. We did this to 
identify the risk of bias or inconsistency in 
application.

 / We assessed the integrity of the Group’s 

AASB 16 lease calculation model, including 
the accuracy of the underlying calculation 
formulas. We recalculated the amount of lease 
liability, right-of-use asset, depreciation and 
amortisation, interest expense, and retained 
earnings relevant to this financial year using 
an independent lease calculation model and 
compared the recalculated amounts against the 
amounts recorded by the Group. 

 / We assessed the disclosures in the financial 
report against our understanding obtained 
from our testing and against the requirements 
of the accounting standard.

Carbon dioxide equivalent is a standard 
measurement used to indicate the impact of 
various greenhouse gas emissions on global 
warming relative to the same amount of  
carbon dioxide (CO2).

Copper concentrate

The Prominent Hill operation produces copper 
concentrate. This is a fine-grained material 
that contains a percentage of copper, gold and
