cent will apply to this allocation and there is no limit on the number of participating shares. 
Shares will be allocated to shareholders under the DRP for the 2020 final dividend at an 
amount equal to the average of the daily volume weighted average market price of ordinary 
shares of the Company traded on the ASX over the period of five trading days commencing 
on 11 March 2021. The last date for receipt of election notices for the DRP is 15 March 2021.  
The financial impact of the dividend amounting to $56.4 million has not been recognised in

MESSAGE 
FROM THE 
CHAIRMAN  
AND CEO
DEAR SHAREHOLDERS, 
2020 was a year that has impacted all 
of us in different ways. At OZ Minerals, 
we applied ourselves to challenges that 
emerged, to protect our people, deliver  
our plans, and harness disruption to 
accelerate our strategic aspirations. 
Our culture enabled us to quickly adapt to 
remote working and a volatile environment. 
Our devolved operating model meant our 
mine sites were able to rapidly respond to 
the changing COVID-19 restrictions, and  
the commitment of our people helped us 
deliver ahead of initial operational targets 
and to advance our strong pipeline of 
growth opportunities. 
We improved our overall safety performance 
with a Total Recordable Injury Frequency 
Rate (TRIFR) of 5.29 compared with 6.27 
in 2019 and lifted our focus on, and 
commitment to, mental health. 
The Total Recordable Injury Frequency (TRIF) 
reporting methodology was updated in 
August 2020 and all data reported from  
1 January 2020 was retrospectively adjusted 
to align with the updated methodology. The 
change (see page 83) takes into consideration 
our move to more flexible work.
GROWTH ENABLED BY CULTURE
In the Prominent Hill Province, the  
Prominent Hill mine cemented its position 
as a low-cost reliable operation while 
demonstrating the potential to increase 
underground production and extend 
mine life by accessing deeper ore with a 
shaft haulage system. With sustainable 
annualised rates at or above 4 million tonnes 
per annum (Mtpa) during the year, future 
decline development spend was brought 
forward to increase mining rates to between 
4 Mtpa and 5 Mtpa from 2022. Accelerating 
the decline development to the bottom  
of the known resource will enable us to 
mine simultaneously from the current  
and deeper levels. 
In the Carrapateena Province, the  
new Carrapateena mine ramped up to its 
4.25 Mtpa run rate and the sub-level cave 
is performing to plan. The Carrapateena 
Expansion progressed to the next study 
phase, following the release of a study 
update showing the potential value uplift  
of converting the bottom half of the sub-
level cave to a block cave, forming the basis 
of a multi-generational mining province.  
In early 2021, the Board approved the  
block cave expansion and early works  
are scheduled to begin in Q4 2021.
In the Musgrave Province, the West 
Musgrave Project increased in value over  
the course of the year. A pre-feasibility  
study (PFS) update released in December 
2020 presents a larger 12 Mtpa mine 
(previously 10 Mtpa) while maintaining the 
same 26-year mine life and powered by  
70–80 per cent renewable energy. 
We acquired our project joint venture 
partner, Cassini Resources, which provides us 
with flexibility regarding future development 
and funding options. 
Exploration activities around the world were 
on hold for most of the year but resumed in 
the latter months within a COVID-19-safe 
framework.
The Brazil team continued to operate while 
managing a much higher concentration 
of COVID-19 cases than had occurred in 
Australia. Their robust processes limited 
cases on site to low numbers at any one 
time and their test, trace and isolate regimes 
prevented widespread infection. The Carajás 
Hub is now taking shape with Pedra Branca 
ore being trucked to the Carajás East 
processing hub. In the Gurupi Province,  
we made progress, though not as much  
as we would have liked, towards removing  
the injunction on the CentroGold Project. 
Our strong operational and financial 
performance allowed for continued 
investment in growth activities, $74.6 million 
in dividends paid to shareholders, and we 
ended the year with a net cash balance 
of $31.7 million. The Board has declared 
a total, fully franked dividend for 2020 of 
25 cents per share, made up of a half year 
payment of 8 cents per share and an  
end-of-year payment of 17 cents. 2020 
earnings per share totalled 65.2 cents.
Culturally and strategically, we advanced  
our Strategic Aspirations including:
   Flexible work with work life plans  
that allowed our people to organise  
their work around their life.
   Zero Scope 1 emissions, zero net  
waste and minimising water use.
   Being Agile by implementing The OZWay 
of operating, ensuring we can adapt 
quickly to future changes. 
   Making innovation easier where our 
people are encouraged to develop ideas 
and collaborate with others outside the 
industry and with the crowd.
   Being data driven, where we gather  
and use data and create insights into 
our business for faster, better, and more 
creative decision making, and to reduce 
manual processes.
STAKEHOLDER VALUE CREATION
We further hardwired value creation for 
our Stakeholders into our governance 
framework and developed a set of metrics 
which will have the dual purpose of being a 
performance assessment tool and focusing 
our work and behaviour. The Stakeholder 
Value Creation Metrics support the 
achievement of our Purpose, ‘Going beyond 
what’s possible to make lives better’. The 
Metrics are published in the Strategy section 
of this report (page 8) and are referenced 
frequently in the Sustainability section.
OZ MINERALS2020 ANNUAL & SUSTAINABILITY REPORTOZ MINERALSMessage froM  the ChairMan and Ceo

The focus is on safe operational delivery  
at our assets, on advancing the project 
studies at Prominent Hill, Carrapateena  
and West Musgrave, and developing out  
the Carajás Hub strategy in Brazil. We’ll  
also be continuing our exploration  
activities where possible. 
We are proud of the achievements of 
our team in 2020, and we have exciting 
opportunities ahead of us including the 
further development of our Modern  
Mining Company culture. 
We thank our people for their dedication 
and energy in delivering results within an 
extremely difficult environment. We greatly 
appreciate the ongoing support of our 
Stakeholders. 
Finally, we thank you, our shareholders, 
for your continued support, trust and 
confidence. 
Rebecca McGrath  
Chairman
18 February 2021
Andrew Cole  
Managing Director and CEO 
18 February 2021
Our Strategy is centred on value creation  
for our five Stakeholder groups – employees, 
communities, governments, suppliers 
and shareholders – and stakeholder value 
creation requires performance across 
multiple dimensions. 
Similarly, the challenges associated 
with sustainable development are also 
multifaceted, involving economic, social,  
and environmental considerations. 
In this respect we created a Stakeholder 
Support Fund to help build resilience for our 
Stakeholders in a COVID-19 environment. 
It will continue into 2021. We made strong 
progress on implementing our roadmap 
for reporting integrated climate risks and 
climate-related disclosures in line with the 
Task Force on Climate-related Financial 
Disclosures framework. We also issued our 
Modern Slavery Statement (ozminerals.com/
sustainability/modernslavery) in support of 
addressing a global issue.
For OZ Minerals, Partnering is a  
strategic enabler for cross-sector and  
multi-disciplinary value creation. This will 
help us gain a greater understanding of our 
context, gain more exposure to diversity 
of thought, and better appreciate what 
constitutes value for our Stakeholders.
LOOKING AHEAD 
Much of the world moved into recession 
in 2020, induced by COVID-19. Many 
countries provided support to their people 
and their economies during 2020. It is not 
known what the full effect will be on the 
individual and world economies when this 
support is withdrawn. However, as countries 
emerge from the pandemic, a period of 
growth is expected. The consensus is that 
the focus on decarbonisation and reducing 
the environmental footprint of business  
will continue, and likely accelerate. 
In this regard, as a producer of copper, 
an important mineral in the renewables 
industry, we are well placed to take 
advantage of potential growth in demand. 
We remain confident about the long-term 
fundamentals of copper. It has seen price 
growth over the course of 2020 reflecting 
supply issues during the year and also 
potential future demand growth, with  
both copper and nickel being key elements 
for the transition to fossil-free electric  
energy production. 
2021 will see OZ Minerals moving into our 
next phase of growth. We have a range of 
greenfield and brownfield options in the 
mature mining regions of Australia and 
Brazil, and our strong balance sheet provides 
financial flexibility for growth opportunities.

STRATEGY
the oZWaY
Creating value for all our Stakeholders – shareholders, 
employees, communities, governments, and suppliers 
– is at the heart of our Strategy. This concept of value 
creation has been embedded into our governance 
systems through our process standards and how we 
assess risk. It drives us to deliver on our Purpose of 
‘Going beyond what’s possible to make lives better’.
OUR STRATEGY
Every year, we review our Strategy to 
ensure it continues to enable us to create 
stakeholder value and be a modern mining 
company. Our Strategy focuses on HOW we 
deliver, and two important elements are:
   Our Purpose – Going beyond what’s 
possible to make lives better which  
was developed in consultation with  
our people.
   The OZWay –  a simple model  
that explains how all the parts of  
OZ Minerals fit together. 
STRATEGIC ASPIRATIONS  
AND ACCELERATION PRIORITIES 
This year, we focused on describing  
OZ Minerals’ Strategic Aspirations. These 
Strategic Aspirations challenge our people  
to realise our full competitive advantage 
in an ever-changing world. Together, 
our Strategy and its embedded Strategic 
Aspirations, support achieving our Purpose 
which is a collective vision for the business 
to work towards. 
These Strategic Aspirations align with 
the Strategy elements. These aspirational 
statements guide our planning and our work. 
They give people permission to stretch their 
thinking and experiment. As we work to 
deliver the Strategic Aspirations, we expect 
to see value created for our five Stakeholder 
groups. 
A Modern Mining Company
During the depths of COVID-19 we 
established a project, Project Beyond, to 
ensure we emerged from the pandemic 
stronger and closer to achieving our 
Strategic Aspirations. Over 450 ideas were 
gathered from across our business which 
were combined with external multi-sector 
benchmarking. These were then refined  
and distilled into our Acceleration Priorities. 
These Acceleration Priorities will help 
modernise how we work, fast-track our 
ethical and sustainable aspirations and  
refine and prioritise the fundamentals  
of our business. They are short to  
medium-term priorities that we would  
have done eventually but have chosen  
to accelerate now. 
The Priorities include:
   normalising and systemising flexible  
and remote work for our people
   moving to the use of agile work 
methodologies 
   removing bureaucracy so innovation  
can occur more freely
   accelerating the implementation of  
a whole-of-value chain, real time,  
data-driven decision-making tool set 
   greater inclusion of our external 
stakeholders in our design teams  
and decision-making processes.

STAKEHOLDER VALUE  
CREATION METRICS
We also developed a set of Stakeholder 
Value Creation Metrics during the year that 
provides a tangible assessment of how 
and where we create value. Reporting on 
these Metrics is aligned with the different 
elements of The OZWay. It also flows 
through to our Purpose, further embedding 
a focus on value creation into what we do. 
Our Stakeholder Value Creation Metrics 
consider:
   what constitutes value from our 
Stakeholders’ perspectives
   the data we currently collect
   how The OZWay applies
   our Strategy, Aspirations and Priorities
   our Purpose. 
We have referenced our Stakeholder 
Value Creation Metrics throughout this 
year’s Annual and Sustainability Report, in 
particular, within our Sustainability Report 
(page 70). The Metrics harness data we 
already collect as part of our operations,  
and presents them in a way that allows 
for clear, consolidated tracking of progress 
against each metric.
In articulating our Stakeholder Value 
Creation Metrics, we can demonstrate 
whether we are creating value for our 
Stakeholders and the Metrics will drive 
behavior within the Company. They  
support our Policies and achievement  
of our Strategic Aspirations and  
Acceleration Priorities.

PROMINENT 
HILL
The Prominent Hill mine 
has met or exceeded 
copper guidance for  
six consecutive years.  
The positive findings 
of the Prominent Hill 
Expansion Study increase 
confidence in Prominent 
Hill’s longevity and 
ongoing performance.
OVERVIEW
   Location: 650 km north-west  
of Adelaide, 130 km south-east  
of Coober Pedy
   Product: Copper concentrate  
(containing gold and silver)
   Mining method: Underground mine
   Processing method: Conventional 
crushing, grinding and flotation
   Mineral Resources: 150 Mt at  
0.9% copper and 0.7g/t gold(a)
   Ore Reserves: 56 Mt at 0.9% copper  
and 0.7g/t gold(a)
(a)  Please refer to the Mineral Resources and Ore 
Reserves section (page 120) for full disclosure.
Prominent Hill is a well established underground 
copper, gold and silver mine located 650 km north-
west of Adelaide in South Australia. Prominent Hill  
is currently operating in the lowest cost quartile 
globally and has delivered on its annual production 
guidance for the past six years. 
In 2018, the mine converted from open pit 
to underground-only operations and ramped 
up to 4 Mtpa in 2020. Plans to increase 
production to between 4 and 5 Mtpa by 
2022 were announced in August 2020 
by accelerating the decline development 
towards the bottom of the known reserve 
to begin mining simultaneously from the 
current and deeper levels. Work started on 
the accelerated development activities in 
September 2020.
A study is progressing into expanding the 
operation further by accessing deeper 
inferred resources via a vertical hoisting 
shaft. A study update released in November 
2020 showed that converting from truck 
haulage to a vertical shaft would lower 
the operational risks and costs of mining 
at depth, be NPV and cashflow positive 
compared to the current truck haulage 
mining operation and create a platform to 
potentially mine deeper mineral resource yet 
to be converted to reserve. 
The positive economics supported continued 
investment in the expansion study with 
further infill drilling to be undertaken to 
increase resource confidence, and to provide 
the basis for a final investment decision 
expected in mid 2021. 
In 2020 Prominent Hill again met its copper 
production guidance. It also met its increased 
gold production targets, and its lower C1 
cost targets, both of which were improved 
mid-COVID-19. In 2020, the team achieved 
a negative C1 cost performance of 54.0 c/lb 
and All-In Sustaining Costs (AISC) of 14.7 c/lb 
assisted by higher gold production and higher 
gold by-product credits. 
Importantly, we continued to focus on how 
we can improve safety, health and wellbeing 
outcomes. The TRIFR of 5.63 was lower at 
Prominent Hill than last year (8.45). Safety 
continues to be a focus for the team into 
2021.

TRANSFORMING  
FOR THE FUTURE
The new 270 km transmission line to 
Prominent Hill via Carrapateena was 
commissioned during the year. It provides 
reliable, secure and affordable power 
transmission for OZ Minerals’ South 
Australian mining assets. The new 
transmission line will also support our  
future expansion aspirations and will  
be available for third party use.
The update on our Prominent Hill Expansion 
Study demonstrated that the installation 
of a vertical hoisting shaft to replace truck 
haulage is technically and economically 
feasible, and has the potential to reshape 
our future. The shaft would have lower 
material handling costs, a higher mine 
production rate and enable development of 
the deeper zones of the known resource  
and potential extensions.
Our understanding of the orebody and the 
mining methods to be used, means we 
are well positioned to de-risk development 
options for this potential expansion. 
OUR FOCUS IN 2021 IS TO: 
   embed our refreshed Critical Risk 
Management Safety Program 
   ramp up underground mining  
rates to 4-5 Mtpa 
   complete the Prominent Hill  
Expansion Study
   continue the conversion of our inferred 
resources to indicated or measured 
   maintain strong operating discipline  
to reliably deliver results in the bottom 
half of the cost curve
   accelerate our drive to embed the strong 
and successful culture of Prominent 
Hill in all our community and supplier 
partnerships
   engage stakeholders in the Prominent Hill 
Expansion and our vision for the Asset, 
and seek their active participation to 
support them.
During the challenging COVID-19-affected 
environment of 2020, we:
   introduced annual programs to support 
health and wellbeing, including mental 
health first aid training to raise awareness 
and reduce the stigma associated with 
mental health issues
   partnered with our Employee Assistance 
Program provider to introduce Yarning 
Circles to provide Indigenous team 
members additional access to peer 
support during the height of COVID-19 
   partnered with Inventium to implement 
their Workday Reinvention Program for 
our workforce, particularly those who 
were transitioning to remote work
   implemented the Keil Centre Resilience 
Program, which helped us understand  
and apply effective coping strategies  
that build personal resilience.
HIGHLIGHTS FOR 2020
   We delivered the targeted 4 Mtpa  
mining rate and accelerated decline 
development to support increased mining 
rates to 4-5 Mtpa from 2022 while 
maintaining mine life.
   We doubled the size of our underground 
resource drilling fleet and completed  
15 km of drilling, with results indicating 
a continuation of the Malu and Kalaya 
mineralisation.
   We delivered an update on the  
Prominent Hill Expansion Study with 
works expected to continue in 2021 
with a view of a mid-2021 investment 
decision. We began Stage 2 drilling of 
the Mount Woods Unearthed Challenge 
targets, drawn from some of the more 
unconventional approaches from the 
2019 Explorer Challenge. 
   We safely and successfully completed 
construction of a new 270 km 
transmission line to Prominent Hill  
via Carrapateena to enable energy  
self-sufficiency for current operations  
and all contemplated expansion  
options from previous reliance on  
Olympic Dam’s power line.
   We commissioned and successfully 
ramped up the Malu Paste Plant 
to nameplate capacity, to enable 
underground performance.
   We transitioned mining into the eastern 
lenses of the Malu underground deposit 
and opened additional mining fronts.
   We upgraded the remote surface 
telemetry systems for the underground 
mining fleet, with associated productivity 
increases.
CLOSING THE LOOP 
ON FOOD WASTE – 
PROMINENT HILL
For the last two years, we have used the 
BioBin© waste management system to 
capture food waste from the camp mess 
and kitchen. Instead of going to landfill,  
this waste is processed to become mulch 
and potting mix. 
This year, we were able to close the loop 
and used this potting mix in a series of 
wicking beds that have been installed along 
one of the camp’s main walkways. The 
plants for the wicking bed were selected in 
consultation with science students from the 
Coober Pedy Area School, who chose local 
plants with medicinal or bush food uses. 
Information plaques have been designed by 
the students and installed to provide some 
local traditional knowledge to camp users.

CARRAPATEENA
Carrapateena is a  
4.25 Mtpa underground 
sub-level cave mine, with 
an estimated mine life of  
20 years. Carrapateena is 
located in a region highly 
prospective for additional 
resources, with known 
mineralisation at nearby 
Khamsin. 
OVERVIEW
   Location: 250 km south-east of Prominent 
Hill, 160 km north of the regional centre 
of Port Augusta, in South Australia
   Product: Copper concentrate  
(containing gold and silver)
   Mine life: ~20 years
   Mining method:  
Underground – sub-level caving
   Processing method: Conventional 
crushing, grinding and flotation
   Mineral Resources: 950 Mt at  
0.57% copper and 0.25g/t gold(a)
   Ore Reserves: 220 Mt at  
1.1% copper and 0.45g/t gold(a)
(a)  Please refer to the Mineral Resources and Ore 
Reserves section (page 120) for full disclosure.
Carrapateena is located in the highly prospective 
Gawler Craton in South Australia, approximately  
250 km from the Prominent Hill mine. It is an  
iron–oxide–copper–gold (IOCG) underground  
mine that first produced concentrate in December 
2019 and has since ramped up to the designed  
steady state production rate of 4.25 Mtpa. 
Carrapateena was officially opened in 
2020 by South Australian Premier, Steven 
Marshall, and the Minister for Energy  
and Mining, Dan van Holst Pellekaan.  
A small number of stakeholders joined  
the ceremony onsite and a much larger 
group of stakeholders joined in real time 
online, as COVID-19 travel and physical 
distancing restrictions were in place. 
The biggest mining project in South Australia 
in the last decade, Carrapateena produced 
27,632 tonnes of copper and 53,089 ounces 
of gold during the year and met copper  
and gold production and cost guidance  
for 2020.
In 2020, Carrapateena achieved a C1  
cost performance of 77.8 c/lb and AISC  
of 122.0 c/lb in its ramp up year. 
We continue to focus on ensuring the safety 
and wellbeing of our people on site through 
training and hazard management. Through 
this work we have reduced the site’s TRIFR 
from 7.24 in 2019 to 6.67 in 2020.
OZ MINERALSCarraPateena

We withdrew from the Maslins JV with 
Investigator Resources during the year, as 
the project failed to intersect any significant 
mineralisation. The Maslins prospect was 
located on the Stuart Shelf approximately  
55 km south of Carrapateena.
OUR FOCUS IN 2021 IS TO:
   continue Carrapateena expansion studies 
and update the Life of Province Plan, 
furthering our province approach
   begin Carrapateena Block Cave early 
works in Q4
   continue construction of the Western 
Access Road
   complete and commission the tailings 
pump upgrade project. This will provide 
critical duty/standby functionality of 
the tails disposal system and increase 
pumping capacity to support milling  
rates up to 5 Mtpa
   continue to improve and optimise  
the processing plant to increase 
throughput and recoveries
   continue to improve our understanding 
of the orebody, with drilling programs 
scheduled to update the ore reserves
   explore additional revenue stream 
opportunities through ongoing studies,  
to extract maximum value from all  
metals and minerals in the ore body 
   start construction of phase two of 
the materials handling system and 
underground mining infrastructure 
   prepare for the second lift of our  
tailings storage facility 
   explore opportunities for automation  
and electrification of mining equipment.
CARRAPATEENA BLOCK  
CAVE EXPANSION
We completed the Carrapateena Block Cave 
Expansion PFS in 2020, and it demonstrated 
that converting the lower portion of the 
current sub-level cave to a series of block 
caves could significantly increase value, ore 
reserves and mine life. 
This expansion would unlock Carrapateena’s 
potential to be a multi-generational, 
lowest quartile cash cost producing 
province, bringing long-term value to our 
Stakeholders. Stage 1 of the Block Cave 
Expansion Feasibility Study is underway and 
is expected to be completed in late 2021. 
LIFE OF PROVINCE PLAN 
We also released the Carrapateena Life of 
Province Plan Scoping Study during the year, 
which considered the future potential of 
resource extensions, satellite deposits and 
exploration targets, including Carrapateena, 
Fremantle Doctor, The Saddle, and Khamsin; 
known collectively as the Carrapateena 
Province. 
The Life of Province Plan Scoping Study 
showed that Block Cave 1 and Block Cave 2 
unlock the broader Carrapateena Province 
potential, including realisation of lower 
grade resources around Carrapateena and  
at Fremantle Doctor. The Life of Province 
Plan is a material opportunity to further 
unlock the Carrapateena Province for many 
decades after Block Cave 2 and provide 
the region with the potential for a multi-
generational mine. 
HIGHLIGHTS FOR 2020 
   We achieved mine nameplate run rate  
six months earlier than planned and the 
cave continued to propagate as planned 
into the Upper Whyalla Sandstone.
   We released the Carrapateena Block Cave 
Expansion PFS and the Life of Province 
Scoping Study, showing that the block 
cave expansion will unlock the potential 
of the broader Carrapateena Province.
   We successfully completed the first major 
mill shutdown and relining without 
incident or injury and ahead of schedule. 
   We completed the cleaner circuit project 
and are awaiting final tie-ins. 
   We commissioned the Jameson Cell 
steelwork, which will increase concentrate 
grade and quality. 
   We commissioned the underground 
crusher and materials handling system 
and both are operating to design 
expectations.
   We began early works on the Western 
Access Road, following pastoralist and 
Traditional Owner consultation. Our land-
connected stakeholders played an integral 
role in determining the best alignment for 
a safe, all-weather, fit-for-purpose road 
that will reduce pastoral interactions and 
avoid cultural heritage sites.
HYBRID ENERGY PLANT
Mining consumes lots of energy, so 
variability, uncertainty and complexity of 
energy supply needs to be well managed. 
Our hybrid energy plant is a unique facility 
located at Carrapateena that is designed 
to host experiments on how various 
equipment and energy technologies  
interact on an operating mine site. 
Our hybrid energy plant serves as a ‘living 
lab’ to attract global organisations into 
South Australia, who wish to test their 
research at an operational mine. The ability 
to do this work remotely also makes the 
option more accessible to collaborators 
from across the globe. 
The hybrid energy plant’s initial setup 
includes solar PV, battery storage, diesel 
generation and a micro-grid controller. 
Additional generation and demand can  
be integrated for testing. 
ENERGY AND MINING 
COLLABORATION 
In 2018, OZ Minerals established the 
Energy and Mining Collaboration (EMC) 
by bringing together a group of individuals 
interested in the challenge of maximising 
the use of renewable energy on a mine 
site. Members of the initiative included 
Adelaide University, CSIRO, the Department 
for Energy and Mining, the Rocky Mountain 
Institute, SunSHIFT and the Tonsley 
Innovation Precinct. Together, this group 
has an extended global reach in terms of 
understanding current and future trends  
in low emissions technologies.  
The purpose of the collaboration was to 
understand how a diverse group of people 
could work together to approach this 
challenge. We know that to achieve real 
breakthroughs, we need to think about, 
and design mines, very differently and 
collaborate widely.  
The group was able to work together to 
understand and highlight the challenges 
and opportunities of multi-stakeholder 
collaborations. Open and honest 
conversations enabled members to gain 
valuable insights into the benefits of this 
way of working, with new relationships 
created and several spin-off opportunities 
being explored. This way of working has 
been recognised by other groups as being 
valuable and we are currently exploring  
this approach with METSIgnited to  
facilitate supplier clusters. 
Importantly, what we have learnt through 
this collaboration has been instrumental 
to the development of frameworks and 
establishment of the new OZ Minerals 
discovery-driven-incubator called Think and 
Act Differently. The EMC will continue to 
contribute to a low emission future through 
the Energy and Emissions accelerator 
program of the incubator.

WEST 
MUSGRAVE 
The West Musgrave Project is a major copper–nickel 
sulphide deposit located in the Musgrave Province of 
Western Australia, approximately 1,300 km north-east 
of Perth. It includes the Nebo-Babel copper–nickel  
and Succoth copper deposits and is currently at 
advanced study stage.  
OZ Minerals now owns 100 per cent of the  
West Musgrave Project after the successful 
friendly acquisition of former joint venture 
partner, Cassini Resources, in October 2020. 
The acquisition gives us more flexibility 
around future development and funding 
options. 
A LOW CARBON, LONG LIFE,  
LOW COST MINE
During the year, we advanced the project 
significantly, producing a PFS in February 
2020 and an updated PFS in December 
2020. Both studies were based on a long-
life, large scale open cut mine producing 
separate nickel and copper sulphide 
concentrates. In the updated PFS, the 
processing plant throughput was increased 
from 10 Mtpa to 12 Mtpa over the same  
26 years, which resulted in an improvement 
to key project metrics with a net present 
value now at ~$1 billion and a life of  
mine undiscounted cashflow in excess of  
$4 billion. This project has the potential 
to be the first development opportunity 
within the broader Musgrave Province, 
which includes several additional, highly 
prospective opportunities. 
West Musgrave is a greenfield site, where 
the existing infrastructure is only sufficient 
for exploration and field work. 
Additional infrastructure will be required  
to support future mining activities and  
we included the following in our PFS: 
   design and costing of site access
   site development and major civil 
infrastructure
   an aerodrome
   450 person village
   a hybrid solar–wind–diesel battery 
solution
   water supply, control systems,  
onsite services
   a full suite of facilities to enable efficient 
construction, mining and ore processing.
To protect the health and welfare of 
our remote community during the early 
COVID-19 period and following subsequent 
restrictions to Ngaanyatjarra Lands imposed 
by the Western Australian Government, we 
paused work at the site in early 2020. 
OZ Minerals is  
aiming to establish  
the West Musgrave  
Project as a scalable,  
low cost, long life, open 
pit mining operation.
OVERVIEW
   Location: Western Australia,  
near the South Australia and  
Northern Territory border
   Product: Copper and nickel

   We sought to crowdsource new solutions, 
systems and approaches to accelerate 
how West Musgrave may become a  
100 per cent renewable-powered  
mine. The Capture the Spark challenge 
helped us identify potential partners  
and pathways.
   We received stakeholders’ endorsement  
of our EPA Part IV submission.
OUR FOCUS IN 2021 IS TO:
   gain EPA Part IV and Part V approval
   progress the project to the next study 
stage
   negotiate a mining agreement with  
the Ngaanyatjarra Group
   trial a fit-for-purpose power generation 
solution and, if successful, incorporate  
it into the West Musgrave Project plan.
We only resumed activities on site when 
restrictions eased, and after the Traditional 
Owners, stakeholders and our team agreed 
it was safe to return. This return to site 
enabled us to consult with the Ngaanyatjarra 
people on our Environmental Protection 
Authority (EPA) Part IV referral and include 
their feedback in the submission. 
This submission to the EPA represents the 
first primary approval to be sought from  
the Western Australian Government. In 
addition, planning and discussions with  
the Ngaanyatjarra Group are ongoing with  
a view to developing a mining agreement 
and progress to the next study phase.  
HIGHLIGHTS FOR 2020
   We acquired Cassini Resources.
   We released the West Musgrave PFS  
that demonstrated a long life ~26-year 
open pit copper and nickel sulphide  
mine with bottom quartile cash costs 
and an average concentrate production 
of 28,000 tonnes per annum copper and 
22,000 tonnes per annum nickel.
   We released a PFS update which saw  
the processing plant increase throughput 
to 12 Mtpa and improvements to key 
project metrics while maintaining the  
26-year mine life.
   We further investigated our innovative 
off-grid renewable power and processing 
solutions, underpinned by up to  
80 per cent renewable electricity 
generation from solar and wind. 
CAPTURE THE SPARK 
CHALLENGE
This year we partnered with Unearthed, 
an energy and resources open innovation 
platform, to create the Capture the  
Spark challenge – where the largest 
community of startups, developers and  
data scientists helped to fast track our  
plans for a 100 per cent renewable  
powered West Musgrave Project. 
The project already has strong sustainability 
credentials. The copper and nickel to be 
mined is critical to the low-carbon economy 
and the project has some 70–80 per cent 
of power generated through renewable 
sources including solar and wind. 
149 participants from 25 countries 
participated in the challenge, and we 
received a total of 31 submissions! 
We’re now bringing these ideas to life in 
partnership with the winning companies 
and co-creating a fit-for-purpose solution. 
This will be trialled at an OZ Minerals site 
where, if successful, it will be incorporated 
within the West Musgrave Project plan.

PEDRA BRANCA 
OVERVIEW
   Location: Carajás Province in the state of 
Pará, northern Brazil, ~100 km south of 
Parauapebas and 30 km east of Canaã 
   Project: High grade copper–gold 
underground mine
   Status: Construction phase, first

(a)  Please refer to the Mineral Resources and Ore 
Reserves section (page 120) for full disclosure.
The Carajás region, in the State of Pará in Brazil, is 
host to a number of large copper–gold mines, and is 
one of the world’s premier IOCG mineral provinces. 
We are pursuing a hub approach to our 
activities in the Carajás whereby a number 
of relatively modest satellite mines produce 
ore which is then trucked to a central 
processing site. The first Hub is at Carajás 
East, where the open pit mine at Antas 
is drawing to the end of its life and the 
existing processing plant will continue to 
be used to process ore from new satellite 
mines. The first new satellite mine is the 
underground mine at Pedra Branca that is 
under construction, with first development 
ore produced in mid-2020. 
Potential additional high-grade copper–gold 
satellite mines are being explored at Santa 
Lúcia and Clovis. A second potential hub has 
been identified at Pantera, which is another 
of our projects in the west of the Carajás. 
Santa Lúcia is one of two earn-in 
agreements we have with Vale S.A. for 
exploration projects in Carajás East. Santa 
Lúcia is approximately 40 km trucking 
distance from Antas; and the less advanced 
but highly prospective Circular North which 
is proximate to Antas.

The Carajás East Hub produced  
8,613 tonnes of copper and 6,312 ounces 
of gold to meet its annual production 
guidance in 2020. 
The Carajás East Hub achieved a C1  
cost performance of 95.4 c/lb and  
AISC of 149.4 c/lb.
At Pedra Branca, milestones were met  
with first developmental ore processed  
into concentrate at the Carajás East Hub  
and concentrate delivered for export using 
Vale’s logistics network to realise  
operational and cost efficiencies.
Ore sorting equipment was installed and 
commissioned at Antas during the year to 
determine the optimal mass versus grade 
ratio for the sorter and for processing. This 
equipment will relocate to Pedra Branca 
once trials are complete.
Our Brazilian operations have not 
experienced major disruptions due to 
COVID-19. 
We implemented many response measures 
to protect the health and wellbeing of our 
people. All non-essential frontline teams 
began working from home while social 
distancing, and health screening and fever 
monitoring programs were implemented 
for incoming site teams. We developed 
processes for contact and environment 
tracing as well as testing, self-isolation  
and quarantine systems and shifted the 
focus of our Health and Wellbeing  
program to COVID-19 related issues, 
including mental health. 
Decline development and the 
implementation of facilities at Pedra Branca 
commenced, resulting in a significant 
increase in the number of employees and 
contractors. A corresponding increase was 
reflected in the TRIFR at Carajás of 4.08, 
which is higher than the previous year 
(1.34).
HIGHLIGHTS FOR 2020
   We implemented a COVID-19 
management plan to minimise the  
risk to our people, visitors, sites and 
broader community.
   The Carajás Hub at Antas received its  
first developmental ore from Pedra Branca 
for processing.
   We began the first phase of the 
strategic Vale–OZ Minerals Cooperation 
Agreement. 
   We installed and commissioned ore 
sorting equipment at Antas and trials 
began to help determine the optimal  
mass versus grade ratio. 
   We conducted resource drilling programs 
at Pantera and Santa Lúcia, with 
encouraging results from Santa Lúcia. 
   We completed eight diamond drill holes 
(~900 m) south of the Antas mine at the 
Paes Carvalho prospect. Results included 
a 15 m zone of strongly altered volcanics 
hosting chalcopyrite and pyrrhotite. 
   We received geophysical results from 
Estrella and numerous prospects within 
the Paes Carvalho prospect.
Through our Stakeholder Support Program, 
we also funded a robust program to support 
the communities where we operate in Brazil 
which were impacted by the pandemic. 
Resource drilling programs began later in the 
year at Pantera and Santa Lúcia after careful 
planning so that we could safely operate in 
a COVID-19 environment. Encouraging early 
results were seen from drilling at both Paes 
Carvalho and Santa Lúcia. We also signed 
a joint venture-type asset agreement with 
Vale and developed a go-forward plan to 
progress various government interactions. 
OUR FOCUS IN 2021 IS TO:
   complete construction and operational 
ramp up at Pedra Branca
   continue to develop the Carajás East  
Hub using the Antas processing plant
   begin the resource definition drill  
program at the Clovis deposit
   maintain processing plant  
performance at Antas
   begin preparations to use the  
de-commissioned Antas pit as  
a tailings storage facility.
SUPPORTING OUR 
COMMUNITIES
COVID-19
We are active members of the communities 
in which we operate, including the cities 
of Água Azul do Norte, Canaã dos Carajás, 
Curionópolis, Ourilândia do Norte and 
Parauapebas. 
At the start of the pandemic, we supported 
these communities with materials and 
equipment and assembled over 7,000 rapid 
tests. We also donated medicine as well as 
personal protection equipment, hygiene and 
cleaning items to our communities. 
Education
In partnership with the professional training 
school Senai, we held courses for the 
Professional Qualification Program, which 
has been running since 2017, and trained 
40 people in the Curionópolis municipality. 
57 people also received their certificates 
of completion for the Project Development 
and Fundraising Course, which took place 
from September to November this year. The 
Course is a joint initiative of OZ Minerals 
and the municipality of Água Azul do 
Norte, in the state of Pará and is aimed 
at providing continuous and free training 
for people working in the social, sports, 
education, tourism and culture sectors. In 
addition, we are working towards offering 
training in mine mechanics and operation  
at Vila Canadá in Água Azul do Norte.

GURUPI
CENTROGOLD 
OVERVIEW
   Location: Gurupi region, in the state of 
Maranhão in northern Brazil, between 
the cities of Belém and São Luis and close 
to existing infrastructure including sealed 
roads, power, water and skilled labour
   Status: Awaiting injunction removal  
to begin feasibility study
   Project: Open pit gold project
   Proposed method: Open pit mine, 
flotation and carbon-in-leach  
processing plant
   Mineral Resource: 28 Mt at 1.9 g/t gold 
(excludes Chega Tudo deposit)(a)
   Ore Reserve: 20 Mt at 1.7 g/t gold(a)
   Mine life: ~10 years
   Estimated annual production:  
100,000–120,000 oz gold(a)
(a)  Please refer to the Mineral Resources and Ore 
Reserves section (page 120) for full disclosure.
The Gurupi Province is in 
the state of Maranhão in 
northern Brazil, between 
the cities of Belém and 
São Luis. Our CentroGold 
project is located in this 
province, close to existing 
infrastructure. It is one of 
the largest undeveloped 
gold projects in Brazil, 
with three main deposits: 
Blanket; Contact; and 
Chega Tudo.
The surrounding CentroGold area is 
considered to host exciting exploration 
potential. Interpretation of a vast database 
of historical information, including 
geophysical, soil geochemistry and drilling 
also suggests potential associated with 
the proximal Cipoeiro deposit and eight 
other known targets including Mandiocal, 
Sequeiro (CentroGold Project) and Mina 
Nova, Vai-e-Volta and Caramujinho  
(Jibóia Project). 
CENTROGOLD
CentroGold’s PFS indicated that a circa 
10-year operation could be developed for 
low capital investment with industry bottom 
half operating costs. Gold production was 
estimated at 190,000–210,000 ounces  
per year for the first two years and 
100,000–120,000 ounces per year on 
average for the life of the mine.
CentroGold has the potential to  
become a Gurupi processing hub, servicing 
nearby deposits such as Chega Tudo and 
Mandiocal, should future drilling and  
studies prove them viable.
This year we continued our focus on 
working to lift the historical injunction 
placed on developing the CentroGold 
project. A Federal Court judge granted 
the injunction in 2013 against the then 
tenement holder citing irregularities in  
the grant of the environmental licence. 
We have been working to gain approval  
for the CentroGold development and 
relocation plan through ongoing discussions 
with INCRA (the Colonization and Rural 
Reform Institute) Brazilia after the local 
INCRA provided their support last year. 
Central INCRA approval has now been 
granted enabling the development and 
relocation plan to be submitted to the 
Brazilian Courts to enable them to lift  
the injunction on the project. 
In parallel to this process, we have worked 
to gain approval for the CentroGold 
environmental update studies with SEMA-
MA (the Environmental State Agency of  
the Maranhão state).
COVID-19 constraints have slowed  
progress in both areas throughout the  
year, as the regulator suspended its 
administrative activities for 60 days in 
response to the pandemic. Planning 
and preparatory work continued so the 
application could progress when the 
regulator resumed administrative activities. 
We are currently updating the CentroGold 
Pre-Feasibility Resource, Reserve and 
Study to include all previous drilling. Once 
complete, the next phase of study for the 
CentroGold project and further regional 
exploration are anticipated to begin when 
the injunction over the project is removed. 
HIGHLIGHTS FOR 2020
   We developed and ran a successful 
COVID-19 management and control plan.
   INCRA’s technical team issued a report 
recommending that authorisation to  
re-establish our environmental license  
be granted.
   INCRA Brazilia granted their approval  
for the relocation plan.
   We progressed updating environmental 
studies in line with the new project 
design.
   We conducted trenching and sampling 
of six targets at Sequeiro, Faixa and other 
targets in Jiboia. 
   We mapped, sampled and augured 
numerous early stage prospects 
throughout the region. 
OUR FOCUS IN 2021 IS TO:
   continue efforts to lift the judicial 
injunction following INCRA approval of 
the relocation plan in December 2020
   complete environmental update studies 
and relocation plan studies
   achieve grant of the installation licensing
   implement the relocation plan
   continue our regional exploration program
   begin an expanded drilling program 
over the CentroGold project and ranked 
exploration targets
   update the Mineral Resource and 
Ore Reserve to support the Definitive 
Feasibility Study metrics
   progress the next study phase of the 
project.

EXPLORATION 
AND GROWTH
We are a growth-
oriented company and 
exploration is central 
to our growth strategy. 
Exploration projects 
allow us to advance 
our strong pipeline of 
opportunities and are key 
to creating value for our 
Stakeholders. 
We hold many exploration projects at 
different stages of maturity, which gives 
us options for how we grow, with capital 
being allocated to the most value-accretive 
projects assessed across our five stakeholder 
pillars. We have a mix of different projects 
like the more mature opportunities from the 
Carrapateena and Prominent Hill expansion 
projects and longer-dated, lower maturity 
ones at a more exploratory stage such as 
Pantera and Paraiso.
We have multiple exploration earn-in 
agreements in place with highly respected 
explorers who offer exploration expertise 
in specific geologies or locations, as well as 
our own exploration programs. In turn, our 
exploration partners gain access to capital 
from us and our more agile approach to 
decision making and execution, to support 
drilling and development programs. We 
typically work with our partners to oversee 
projects, in particular, the technical program 
and stakeholder engagement, while they 
manage on the ground activities.
COVID-19 saw us temporarily restrict 
exploration drilling in 2020 to protect the 
health of our people and communities. 
Much of our exploration work is undertaken 
in regional and remote communities, who 
are among the most vulnerable. When 
conditions eased, we progressively started 
exploration drilling under strict safety 
management plans and in accordance with 
the restrictions of the different jurisdictions. 
During the year we entered into two new 
earn-in agreements. 
We withdrew from the Maslins joint venture 
with Investigator Resources in South 
Australia, where the stage one drill program 
on the Maslins prospect, located on the 
Stuart Shelf approximately 55 km south 
of Carrapateena, was completed. We also 
withdrew from the Nullabor project within 
our multi-site exploration alliance with Red 
Metal Limited after drilling failed to find 
evidence of IOCG mineralisation. 
EXPLORATION PORTFOLIO
Mt Woods
Continuing to push the boundaries of 
exploration the company completed five 
holes during the year, for ~2,000 m, 
testing some of the unconventional targets 
generated by the Unearthed Challenge. 
Targeting methodologies included using 
geophysical software associated with the 
oil and gas industry, data science near miss 
algorithms and 3D seismic interpretations. 
Information generated in this phase of 
drilling will be utilised to generate/validate 
drill targets for the 2021 field program.
Eloise joint venture  
with Minotaur Exploration
In December 2015, we entered into a 
binding Heads of Agreement with Minotaur 
Exploration for the Eloise Project, located 
near Cloncurry, Queensland.
The Cloncurry Mineral District contains 
strong mineral endowment in a variety 
of commodities, including copper–gold 
(Ernest Henry, Eloise, Osborne and Mount 
Elliot/Swan deposits) and zinc–lead–silver 
(Cannington, Pegmont). The geology of the 
tenements indicates excellent prospectivity 
for high-grade Eloise-style copper–gold and 
Cannington-style zinc–lead–silver deposits.
Minotaur Exploration collected 
electromagnetic (EM) data at Eloise and 
identified two significant anomalies, named 
Little Foot and Big Foot. The prospects are 
located along strike of previously identified 
copper and gold mineralisation at the Electra 
and Iris prospects. The Seer, Little Foot, and 
Big Foot targets were tested and minor 
intervals of visible sulphide mineralisation 
were encountered on all prospects. 
Jericho joint venture with 
Minotaur Exploration
We have an 80 per cent beneficial 
interest in the Jericho project undertaken 
with Minotaur Exploration. The 2020 
field program began with a ground 
electromagnetic survey focused on targets 
north-east of the Iris/Electra prospects. 
More than 28 line kilometres of data were 
acquired over 10 lines (on 400 m and 800 m 
apart) before the program was suspended 
due to COVID-19. 
Minotaur Exploration published the maiden 
resource for the Jericho project early in July. 
However, we have determined the present 
resource is not viable as a standalone 
underground mining operation. Exploration 
efforts will now focus on other high priority 
targets within the tenure.

Multi-site exploration alliance 
with Red Metal Limited
This alliance gives OZ Minerals a two-year 
option to fund a series of mutually agreed, 
proof-of-concept work programs on Red 
Metal’s early-stage projects, which include:
   Yarrie for copper–gold and copper 
–cobalt in Western Australia
   Gulf for copper–gold in Queensland 
   Three Ways for zinc–lead–silver  
in Queensland 
   Lawn Hill for zinc–lead–silver  
in Queensland
   Mount Skipper for zinc–lead–silver 
–copper in Queensland.
Red Metal Exploration Alliance completed 
drilling of one hole at the Mt Skipper project 
and two holes at the Three Ways project. 
Mt Skipper returned no visually significant 
intersections and minor vein-hosted and 
disseminated chalcopyrite was encountered 
at Three Ways. Drill rigs have demobilised 
from both projects and magnetotelluric (MT) 
surveying is currently underway at Lawn Hill.
One diamond drill hole (666.3 m) was 
completed on the Nullarbor Plain. No 
evidence of an IOCG mineralising system 
was detected and we subsequently 
withdrew from the agreement. 
Lannavaara with Mineral 
Prospektering i Sverige AB
We entered into an agreement in 2018 
with private explorer Mineral Prospektering 
i Sverige (MPS) to explore for IOCG 
mineralisation in the Norrbotten district  
of northern Sweden.
Historic exploration on the leases by 
previous explorers intersected a copper and 
zinc skarn system on the Huornaisenvuoma 
prospect in the south-west of the license 
and they also defined two small magnetite-
hosted iron occurrences, Kevus and Teltaja. 
Subsequent gravity and EM surveying by the 
Swedish Geologic Survey (SGU) revealed a 
continuous, 3.8 km long, untested gravity 
anomaly between Kevus and Teltaja with a 
coincident EM response.
Late in the quarter Mineral Prospektering 
i Sverige commenced a winter drilling 
program at the Lannavarra project in 
Sweden. Two holes were completed for  
315 m before breaking for the festive  
period and drilling recommenced in  
early January 2021.
Painirova project with Mineral 
Prospektering i Sverige AB
Painirova is located between the Mertainen 
iron–oxide–apatite deposit and the active 
Leveäniemi mine at Svappavaara in Sweden’s 
most prolific mining belt. On the back 
of airborne electromagnetic (AEM) data 
collected over the tenement (2019) we 
elected to proceed with the project into 
2020 and have committed to drilling a 
number of high ranked targets.
Paraiso with private Peruvian 
company Inversiones Mineras  
La Chalina S.A.C.
We entered into an earn-in agreement 
in 2018 with private Peruvian company 
Inversiones Mineras La Chalina S.A.C. to 
explore for IOCG deposits in the Arequipa 
district of southern coastal Peru. At the 
Esmeralda target zone, surface copper oxide 
mineralisation has been traced over a strike 
length of 400 m. At the Casper target a 
400 m by 300 m copper-in-soil anomaly has 
been outlined by previous explorers. Neither 
target has been drill-tested. The initial work 
program is planned to include geological 
mapping, rock chip and soil sampling, 
ground geophysics and an airborne 
magnetic survey.
Brazil – Carajás Exploration
We have an extensive portfolio of 
exploration projects centred around our 
operating copper mines, Antas and Pedra 
Branca. Although the field program in Brazil 
was significantly impacted by the COVID-19 
pandemic, 17 holes were completed during 
the year. The exploration team successfully 
completed drill programs on the Gueroba, 
Tapuia, Campo Grande and the Canaã West 
targets. Encouraging results were returned 
from both Gueroba and Canaã West, areas 
identified for further work.
Brazil – Pantera
Pantera is a high-grade copper–gold 
exploration project covering approximately 
100 km2 in the western part of the Carajás. 
Drilling, with more than 4,200 m completed, 
was undertaken in 2020 with the aim of 
identifying a maiden JORC Mineral Resource.
Brazil – Santa Lúcia
The Santa Lúcia project is a small high  
grade copper–gold deposit located south 
of the Antas mine in the Carajás. Acquired 
from Vale in 2019, the project team has 
focused on infilling the existing drilling  
and has completed over 40 holes for  
more than 5,700 m. The team is working 
towards delivering a maiden resource 
estimate in 2021. 
THE POWER  
OF THE CROWD
We believe that great innovations can 
be unleashed when industries and 
people come together and collaborate. 
Crowdsourcing and collaboration are great 
ways for us to build business capability and 
challenge the status quo while working to 
solve some of our most complex problems 
in exploration and growth. 
We have applied this to our exploration 
approaches, starting with the Explorer 
Challenge in 2018. In 2020, we took  
this approach further, to expand our 
exploration toolkit. 
Drillanthropy
Drillanthropy is an initiative aimed at 
science-driven exploration across South 
Australia more broadly. Drillanthropy 
provides funding for tenement holders to 
drill test artificial intelligence and machine 
learning generated targets and models  
on their tenements. With a successful 
discovery, tenement holders could  
secure a partnership with us.
Data-driven exploration models have been 
multiplying across South Australia as a 
direct result of the Explorer Challenge,  
the SA Government’s Gawler Challenge,  
and renewed interest in machine learning 
across the mining industry. 
Drillanthropy is our way of connecting  
these new ideas to the funding needed  
to test them.
Copa de Cobre 
Our Copa de Cobre Challenge sought 
to define new search spaces for copper 
exploration in Peru by generating a  
data-driven domain map of Peru using 
satellite data, and supplements our  
existing exploration strategy in-country. 
A significant amount of country-scale 
satellite data was collected and made 
publicly available. Participants in the Copa 
de Cobre Challenge then used the data 
and applied machine learning to generate 
feature maps that highlight geological 
patterns, which could then be used for 
exploration and identifying new regions  
in Peru that potentially host copper 
deposits. This challenge was truly global 
with winners of the Challenge coming from 
France, South Korea, USA, Brazil, and Russia.

accountability and provide criteria for 
measuring value creation performance.
The Global Performance Standards are used 
to audit Asset performance and set the 
minimum standards for any new Assets.  
They are provided to contractors and 
partners to outline what we expect when 
working at an OZ Minerals Asset. These 
documents are designed so that Assets, 
contractors or partners 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 this model by defining 
the accountabilities and authorities of our 
Board, CEO, Executive Leads and Leads of 
the Corporate Functions and Assets relating 
to key business processes and management 
activities that are unique to us. The Global 
Process Standards are internal documents. 
OUR PERFORMANCE
Internal and external audits
Risk management, audit and assurance 
underpin the Global Process and 
Performance Standards as critical elements 
of our Audit and Assurance Governance 
Framework.
We conduct regular audits and assurance 
reviews commensurate with our risk 
profile as part of our Four Lines of 
Defence approach to systematically and 
objectively verify our compliance with 
Global Performance and Process Standard 
accountabilities and legal requirements. We 
apply learnings from audit and assurance 
reviews to continuously improve our safety, 
health and wellbeing, along with our 
environmental and social performance.
Our governance framework enables 
lean business processes that drive clear 
accountabilities and create room for 
innovation. It is explained through  
The OZWay. The OZWay model includes 
our Purpose, desire to be a modern mining 
company and Strategy to create value for 
our Stakeholders.
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 Assets, partners, suppliers and 
employees of 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 outlines what  
is expected of everyone who works at 
OZ Minerals. It is designed to ensure that 
everything we do at OZ Minerals creates 
value for our Stakeholders and business  
is conducted with honesty and integrity  
so we can achieve our Purpose of ‘going 
beyond what’s possible to make lives  
better’. It addresses issues such as conflicts 
of interest, gifts, entertainment and 
hospitality, anti-bribery and corruption, 
professional behaviour and fair dealing,  
and speaking up.
We are 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 it 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.

SIGNIFICANT CHANGES IN STATE OF AFFAIRS
   Carrapateena is an underground copper mine in South Australia which has a long mine 
life and growth prospects. OZ Minerals produced first saleable concentrate at the end of 
the prior year at the Carrapateena copper–gold mine which ramped up to full capacity by

through the acquisition of Cassini Resources Limited consolidating OZ Minerals’  
ownership of West Musgrave to 100 per cent providing full optionality in determining  
its development.

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 Leadership Team and the 
Sustainability Committee of the Board 
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 reasonable assurance over  
OZ Minerals’ energy and emissions report.
KPMG has also provided limited assurance 
over selected metrics and disclosures in 
this document against the requirements of 
the Global Reporting Initiative Standards. 
KPMG’s assurance report is available on 
pages 118 and 119.
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  
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.

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 127 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.

In addition to the amounts disclosed above, Cassini Resources Pty Ltd incurred $216,816 in relation to the tax compliance and 
advisory services provided by KMPG prior to the acquisition by OZ Minerals.
Following the Audit Committee’s 
consideration of KPMG providing non-audit 
services and its subsequent recommendation 
to the Board, 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; and
   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 
resolved on 18 February 2021 to pay a fully-
franked dividend of 17 cents per share. The 
record date for entitlement to this dividend 
is 12 March 2021. 
OZ Minerals offers a Dividend Reinvestment 
Plan (DRP) and eligible shareholders may 
participate in the DRP in respect of all or  
part of their shareholding. A discount of 
1.5 per cent will apply to this allocation  
and there is no limit on the number of 
participating shares. Shares will be allocated 
to shareholders under the DRP for the 
2020 final dividend at an amount equal to 
the average of the daily volume weighted 
average market price of ordinary shares of 
the Company traded on the ASX over the 
period of five trading days commencing on 
11 March 2021. The last date for receipt 
of election notices for the DRP is 15 March 
2021.
The financial impact of the dividend 
amounting to $56.4 million has not been 
recognised in the Consolidated Financial 
Statements for the year ended 31 December 
2020 and will be recognised in subsequent 
consolidated financial statements.

FINANCIAL 
REVIEW
OZ Minerals’ net profit after tax (NPAT)  
for the year was $212.6 million compared  
to $163.9 million for 2019, assisted by 
higher gold volumes accompanied by a 
stronger gold price. While the volume of 
copper sold was lower following depletion 
of the high-grade copper ore stockpiles at 
Prominent Hill, the addition of Carrapateena 
in its first year of operation, offset some of 
this reduction and contributed to the full 
year result.
While the fundamentals for copper remain 
solid, the COVID-19 pandemic induced 
economic uncertainty through the year, 
initially impacting price adversely before 
recovering towards the end of the year. The 
ensuing economic uncertainty drove a surge 
in demand for gold, beneficially impacting 
its price in a volatile market. 
OZ Minerals’ customers continued to 
operate during the year with minimal 
interruption and movement of concentrates 
remained unhindered. With limited exposure 
to the Chinese market, no disruptions were 
experienced as a result of current trade 
tensions between Australia and China.
The Company’s margin for earnings  
before interest, tax, depreciation and 
amortisation (EBITDA) remained robust  
at 45 per cent (2019: 42 per cent).
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. 
The operation also benefitted from a positive 
reconciliation of stockpiled gold ore grades 
and better than expected metal recovery. 
At the Carrapateena mine, performance of 
the processing plant and underground mine 
exceeded original construction expectations 
and ramped up to full production within 
12 months of commissioning. Expansion 
studies beyond the initial sub-level cave 
progressed during the year, culminating in 
the Board providing its approval, following 
the end of the year, to proceed with the 
next stage for developing the larger resource 
at Carrapateena. 
The Antas mine in the Carajás Hub 
continued production through the year  
as it approaches end of mine life, while 
the Pedra Branca mine transitioned to 
operational status in the fourth quarter of 
the year as it reached the primary orebody. 
Exploration and corporate development 
expenditure decreased following the 
decision to conserve cash in response 
to the COVID-19 pandemic and access 
to exploration sites was restricted. 
Nevertheless, significant milestones were 
achieved with the completion of the West 
Musgrave PFS in February, the Carrapateena 
Expansion Pre-feasibility and Carrapateena 
Province Scoping studies in June and the 
West Musgrave PFS Update in December. 
In the second half of the year, OZ Minerals 
consolidated its ownership of the West 
Musgrave Project through the acquisition 
of Cassini Resources Limited and now fully 
owns the project.
OZ Minerals extended its revolving debt 
facility to circa $480 million in response to 
COVID-19 uncertainty, providing sufficient 
liquidity headroom for the business to 
continue operating and against which the 
balance drawn down at the end of the year 
was $100.0 million. 
As a result of strong operating cashflows in 
the second quarter, the Company concluded 
the year with a pre-debt cash balance of 
$131.7 million. During the year ongoing 
investments were made at Carrapateena, 
Prominent Hill underground and Pedra 
Branca, along with tax payments to the 
government and dividend payments to 
shareholders.

At the Carajás Hub, following completion of 
the open pit cutback in 2019, mining costs 
reduced significantly resulting in production 
costs being lower by $15.5 million. Costs 
relating to the Pedra Branca project were 
capitalised through until the end of October 
in line with its development schedule. 
A positive net realisable value (NRV) 
adjustment of $66.5 million was recognised 
in relation to inventory, which also included 
a write down of obsolescent stores and 
ore. This compared to an NRV write up of 
$27.8 million in the comparative period. 
The write up of NRV during the year was 
mainly due to assumed gold price and earlier 
anticipated processing of ore stockpiles.
EXPLORATION AND CORPORATE 
DEVELOPMENT EXPENDITURE
Exploration and corporate development 
expenditure of $50.5 million was 
incurred during the year to progress the 
Carrapateena expansion study; drilling and 
development studies in the Carajás and 
Gurupi provinces; and other exploration 
earn-in arrangements in the growth 
pipeline. Key spend areas included:
   Carrapateena expansion $16.9 million
   Carajás and Gurupi study costs and 
exploration $9.9 million
   other exploration and development 
expenditure $23.7 million.
OTHER EXPENDITURE
Corporate general and administration 
costs of $56.0 million were largely related 
to direct corporate activities. The increase 
of $5.8 million over the comparative 
period was mainly due to an increase in 
depreciation and amortisation following 
a review of information technology assets 
which have a relatively shorter useful life. 
A provision for potential one-off legal costs 
was also recorded.
The income tax expense of $83.2 million 
was $18.5 million higher than the previous 
year as a result of the higher profit and 
partly offset by the benefit of restricted prior 
year tax losses recognised during the year.
Finance expense of $27.1 million was  
$22.2 million higher than the previous year 
with debt facility charges and lease finance 
expenses also being recognised under  
AASB 16 Leases.
REVENUE
Gross revenue of $1,377.8 million  
was higher than the previous year by  
$203.8 million, mainly due to a higher 
volume of gold sales, which more than 
offset a reduction in copper sales during the 
year. The volume of contained copper sold 
during the year was circa 19,000 tonnes 
lower while contained gold sold was circa 
101,000 ounces higher. The realised $A 
copper price was 11 per cent higher than 
in the comparative period while the net $A 
gold price was 20 per cent higher. Revenue 
includes $92.7 million in realised losses on 
gold hedges. The net proceeds from the sale 
of concentrate attributable to ore mined 
during development of the underground 
mine at Carrapateena of $37.2 million and 
Pedra Branca of $5.8 million was recorded 
as a reduction against the previously 
capitalised costs of developing each  
mine and not recognised in revenue.
REALISATION COSTS
Treatment charges and refining costs 
(TCRCs) were $31.1 million lower as a 
result of improved trading terms and lower 
refining charges in the global market.
Royalty expense increased by $10.1 million 
due to the increase in net revenue, partially 
offset by a lower state royalty rate applicable 
to Carrapateena for the first five years.
PRODUCTION COSTS
Total production costs of concentrate 
sold were $151.6 million higher than the 
comparative period mainly due to the 
inclusion of Carrapateena which added 
$251.4 million to production costs following 
first saleable concentrate production 
towards the end of 2019. This was partially 
offset by a reduction of $99.8 million 
predominantly at Prominent Hill.  
Lower processing volumes year on year 
contributed to production costs for 
Prominent Hill being $73.3 million lower 
than the comparative period, despite offsets 
from a higher proportion of underground 
ore and an increase in power infrastructure 
costs following the activation of the new 
power line in the last quarter of the year. 
While continued processing of open pit 
ore stockpiles to supplement high grade 
underground ore contributed to a lower 
cash cost outcome for the mine, the cost  
of ore inventories processed from stockpiles 
was included within total production costs.
During the year, costs attributable to the 
processing of ore extracted during the 
development of the Carrapateena and Pedra 
Branca mines were capitalised. Following the 
commencement of operations, production 
costs were subsequently recognised within 
the Income Statement.

OPERATING CASH FLOWS
Operating cash flows of $550.4 million  
for the year were $39.8 million higher  
than in 2019 mainly due to higher receipts 
from customers from higher revenues 
and lower payments for exploration and 
corporate development activities.  
Customer receipts during the year were 
higher by $113.1 million with higher  
gold volumes and price driving revenue. 
Payments to suppliers and employees  
were $589.2 million for the year,  
$96.5 million higher than in 2019 with 
the inclusion of operating costs relating 
to Carrapateena production. Payments for 
exploration and corporate development 
expenditure decreased by $49.4 million 
reflecting the impact of reduced activity 
following access restrictions due to the 
COVID-19 pandemic. PAYG tax payments  
of $43.8 million were in line with the 
previous year.
Financing costs included in operating 
cashflow increased during the year by  
$20.7 million because of debt servicing 
facility commitment fees and interest 
charges which were incurred following the 
extension of the revolving debt facility and 
draw down of debt during the year.
INVESTING CASH FLOWS
Net investing cash flows of $520.2 million 
were attributable to development costs at 
Carrapateena, property, plant, equipment 
and mine development at Prominent Hill  
and the Carajás, and study costs associated 
with the West Musgrave Project. These 
cashflows were partially offset by net 
proceeds from the sale of concentrate 
attributable to ore mined during the 
development of Carrapateena and Pedra 
Branca. The payments incurred related to:
   capitalised Carrapateena development 
costs of $392.6 million, including net 
proceeds from the sale of concentrate  
of $37.2 million
   Prominent Hill mine development  
costs $43.3 million
   site sustaining capital expenditure  
$31.9 million
   Carajás capital expenditure $32.6 million 
including Pedra Branca mine development 
expenditure of $22.2 million and net 
proceeds from sale of concentrate of  
$5.8 million
   West Musgrave capitalised exploration 
and evaluation costs $16.2 million
   other capital expenditure $3.6 million.
FINANCING ACTIVITIES
Cash outflows relating to financing activities 
were $28.4 million comprising $73.2 million 
in dividend payments to shareholders,  
$55.2 million in payments to suppliers 
classified as lease payments under AASB 16 
Leases and a $100.0 million net drawdown 
of the debt facility.
Since the end of the year, the Board has 
resolved to pay a final dividend for the 2020 
financial year amounting to $56.4 million. 
This final dividend will be fully franked for 
Australian tax purposes and eligible for the 
dividend reinvestment plan.

BALANCE SHEET
The total equity of the Company increased by $231.5 million to $3,211.4 million. The increase resulted mainly from the year’s NPAT of 
$212.6 million and share capital issued to acquire the residual interest in the West Musgrave Project from the shareholders of Cassini 
Resources Limited. Movement in gold derivative contracts of $24.1 million, partially offset by returns to shareholders in the form of dividends 
amounting to $74.6 million and a decline in foreign currency translation reserve of $37.4 million, reduced total equity. The movement in the 
net assets of the Group since 31 December 2019 is provided below.

2020
At the end of the year, the Company held a cash balance of $131.7 million and a debt balance of $100.0 million on its credit revolver.  
The increased debt facility of circa $480.0 million provided added liquidity and flexibility during COVID-19 as well as enabled the continued 
execution of the Company’s growth Strategy. 
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 general Property Plant and Equipment (PP&E), as well as the payment of dividends. Inventories of $518.7 million at  
the end of the year had reduced by $18.9 million since 1 January 2020. As open pit ore from stockpiles were consumed in the production  
of concentrate, the associated costs were recognised in the income statement within inventory adjustments. 
The net NRV adjustment of $66.5 million increased the value of the remaining inventory.
Trade receivables increased due to the timing of shipments, with shipments for all three operations occurring in the second half of 
December.
PP&E and exploration assets increased during the year mainly due to capital expenditure at Carrapateena; the acquisition of the remaining 
30 per cent interest in the West Musgrave Project; capitalisation of underground development expenditure at Prominent Hill; capitalised 
West Musgrave exploration and study costs; and general sustaining capital expenditure. This was partially offset by depreciation and net 
proceeds received from the sale of concentrate attributable to ore mined during the initial development of both the Carrapateena and  
Pedra Branca mines.
Additional right-of-use (ROU) lease assets and liabilities were recognised during the year associated with the extended Prominent Hill  
mining services contract and the power infrastructure contract. The amounts are included as part of Borrowings on the balance sheet.

RISK MANAGEMENT OVERSIGHT 
AND GOVERNANCE
Board 
The Board sets the Company’s risk appetite 
and oversees the management framework 
and effectiveness of the systems of internal 
control and risk management. It also reviews 
and monitors the material risks of the 
Company.  
Reporting of material risks to the Board 
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 the CEO and 
Executive leadership to implement a system 
of controls 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, audit, 
disclosure processes, internal financial 
controls, cyber and digital risk, funding 
and financial risk management (including 
internal and external audit functions).
The Sustainability Committee assists the 
Board in the effective discharge of its 
responsibilities in relation to safety, health, 
environment, and community (SHE&C), 
and oversight of the risks relating to those 
matters. This includes risks relating to

  The first line of defence  
– Identify and Implement
Global Process Standards define the 
approval escalations between the Board, 
CEO, Assets and Corporate Functions 
based on risk. The Risk Management 
Process Standard outlines the mandated 
process for escalation and the roles 
of organisational authority levels in 
risk reduction. 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  
– Enable and Monitor
The senior leadership of the Assets and 
Corporate Functions ensure compliance 
with the minimum controls in OZ Minerals’ 
Global Performance and Process Standards 
and provide subject matter expertise and 
insights to support the delivery of the 
standards.
  The third line of defence  
– Independent Internal Audits
All Global 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 Audits
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.
Managing risk 
Our risk framework commits us to managing 
risks in a proactive and effective manner.
Effective risk management requires the 
identification and assessment of the 
risks that matter most in achieving the 
Company’s strategic objectives, so resources 
can be prioritised in the most efficient and 
effective way. 
Material risks are managed in the context  
of supporting the successful delivery of  
OZ Minerals’ Strategy. Risks are initially 
assessed to determine their Highest 
Credible Impact (HCI) without critical 
controls, through the lens of OZ Minerals’ 
Stakeholder Value Creation, using Impact 
Assessment criteria. The effectiveness of 
current critical controls – to prevent threats, 
enable opportunities and respond to HCIs 
– are assessed to determine the Current 
Residual Risk Rating.
Where controls for a risk are assessed as 
requiring improvement, management plans 
are developed and implemented to improve 
those controls and to ultimately achieve a 
Target Residual Risk Rating – moving the 
risk to a ‘Well Controlled’ status. Current 
material risks are required to be reviewed 
every six months at a minimum to determine 
whether our exposure to the risk continues 
to remain within our risk appetite.
42
Risk movements
Changes in geopolitics, macroeconomics, 
the impact of COVID-19, an enhanced ESG 
focus, and the continued evolution of our 
risk management processes themselves have 
changed our material risks since 2019.
In particular, we continue to consider the 
implications of the COVID-19 pandemic 
on our business, including assessing its 
potential short and long-term effect on 
the Company’s risk profile, heightening a 
number of the risks listed on the following 
pages. These include supply-chain 
interruptions, mobility, workforce flexibility, 
the commodity market cycle, resource 
nationalism, trade flow impacts, and the 
resilience of global financial markets to 
support recovery outcomes. Each of these 
could materially affect our communities, 
suppliers, shareholders, governments,  
and employees, impacting our ability to 
create value.
Company risk categories  
and material risks
The allocation of our material risks against 
the Company’s primary risk categories is 
shown in the table on the following page, 
with further analysis described in the 
subsequent risk descriptions. 
In identifying our material risks, we have 
considered the likelihood and potential 
impact of the related events. Key changes 
to our inherent material risks, primarily due 
to the external environment and ongoing 
global political instability, are presented 
within the table. Changes are determined 
based on the inherent risks before the 
application of controls and response plans 
to reflect these uncertainties. Company 
strategic controls and actions to prevent, 
reduce, or mitigate downside risk events 
and increase the likelihood of opportunities 
being realised are provided against each  
risk item. 
Our process for identifying, assessing, 
managing, and reporting material risks is 
designed to manage opportunities that 
facilitate or exceed, and threats that may 
hinder, the achievement of the Company’s 
Strategy and, where appropriate, to accept 
a degree of risk to create value for key 
stakeholders. We have an enterprise-wide 
digital risk management information system 
where all material risks, controls and actions 
are documented and kept current for 
managing and reporting purposes.
The Board and Committees review and 
consider the Company’s risk profile, 
including strategic, operational, new, and 
emerging risks based on the monthly, 
quarterly, and annual material risk reports. 
The reports include an overview of the risk 
profile, summary of material changes to the 
profile, key risks in focus, and updates on 
emerging Company and sector risk themes.
The ELT reviews, and the CEO approves, 
new (or changes to) material risks, a process 
facilitated by the enterprise-wide digital 
risk management information system. On a 
regular basis, members of the ELT deep dive 
into selected topical material risks with risk 
owners to validate the adequacy of critical 
controls and to continue elevating our risk 
maturity journey. 
Emerging risks and uncertainties
There remain significant implications for 
the Company that arise from periodic 
and sometimes ever-growing geopolitical 
tensions impacting market sentiment. 
Examples include rising trade tensions 
between nations, geopolitical friction, and 
the potential for the COVID-19 pandemic 
to slow global growth and impact demand 
for our products. Additionally, there is a 
continuing focus on resource nationalism. 
This has the potential to adversely affect 
Company earnings and value creation for 
other stakeholders. 
During the year, we again saw a rise 
in societal expectations regarding the 
potential impact of the mining sector, 
including our business, on the local 
economy, communities, and environment. 
There has also been an increase in focus 
by investment firms on environmental, 
social and governance (ESG) issues when 
reviewing their investment criteria. Risk 
management, including on ESG issues, has 
formed part of our governance framework, 
strategic thinking, and investment decision 
criteria throughout the year. We continue to 
enhance our monitoring and management 
of greenhouse gas (GHG) emissions, water 
and land use, waste, and rehabilitation.

mergers, acquisitions and divestments.
Threat: Ability to create value for key stakeholders 
by successfully executing mergers, acquisitions and 
divestments may vary and could result in value 
destruction by realising less than the fair value 
for divestment or paying more than fair value for 
acquisitions.
Opportunity: Ability to successfully acquire and 
integrate businesses on favourable terms provides 
sustainable future cash flow and future growth 
optionality.

Project development, execution, and delivery
Threat: The Company’s ability to deliver projects 
successfully and safely may vary due to changes  
in technical requirements, or through commercial  
or economic assumptions proving inaccurate  
through the execution phase.
Opportunity: An ability to develop projects  
safely, on time, and within budget enhances 
the Company’s reputation, demonstrate social 
performance, stakeholder confidence, and increases 
cash flow and returns to all stakeholders.

Threat: The ability to prepare for and manage 
potential physical impacts (acute and chronic)  
such as increased extreme weather events and 
transition impacts including increased regulation, 
market shifts or changes to technology and  
energy sources.
Opportunity: Climate change has the potential  
to be a catalyst for growth in low-carbon industries

Governance and Relations
Geopolitical stability
Threat: Political uncertainty, trade protectionism, 
increase in stakeholder expectations, and changes  
in relations between countries in which we operate,  
or where our customers or supplies operate, can 
impact our ability to access resources and markets 
needed to achieve our Strategy.
Regulatory, regulation & compliance
Threat: The Company’s activities by employees, 
directors or partners could result in actual or  
perceived breaches of legal, regulatory, ethical,  
or human rights compliance obligations or 
inappropriate business conduct.
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 our Stakeholders.

Threat: The underground mining operations are 
subject to geotechnical uncertainty, adverse ground 
conditions, decline/mine collapse, cave-ins, rock falls, 
fire, and uncontrolled explosion incidents. 
Production and Operations
Third Party Performance
Threat: Contractors, suppliers, and strategic 
partnerships play a significant role in delivering the

Commercial and Market
Commodity Market Cycle
Opportunity: An increase in demand for emission free 
energy, 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 Stakeholder support.

Threat: 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. 
Also, the inability to discover new resources or 
projects could undermine the future growth pipeline.
Opportunity: The discovery of a new viable orebody 
can significantly improve future growth options. In 
addition, the economic viability of some Ore Reserves 
and mine plans can be restated upwards.

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 2020 
Remuneration Report for OZ Minerals.
We are proud of the Company’s exceptional 
performance in 2020 with strong financial, 
operational and strategic outcomes 
notwithstanding the unprecedented 
challenges that the COVID-19 pandemic 
presented. Highlights include:
   our agile, innovative and collaborative 
culture enabling us to quickly adapt to 
remote and new ways of working to 
ensure that our people, contractors, 
suppliers and the communities in which 
we work were safe whilst continuing 
to deliver on challenging operational 
budgets and strategic plans
   Prominent Hill meeting production 
targets and the underground mine 
demonstrating a 4 Mtpa run rate, whilst 
reducing unit costs from $95/t to $85/t; 
with an expansion study demonstrating 
the viability of a shaft haulage system to 
access deeper ore enabling an increase in 
underground production and an extended 
mine life
   Carrapateena meeting production targets 
and safely completing the successful 
ramp up to its 4.25 Mtpa run rate ahead 
of plan and without compromise to the 
sub-level cave performance; and a PFS 
demonstrating a material value uplift 
through a block cave expansion which 
will increase production to 12 Mtpa and 
significantly extend mine life
   acquisition of our West Musgrave  
Joint Venture partner, Cassini, and a  
25 per cent increase in NPV of the  
West Musgrave Project to circa  
$1.0 billion, reflecting a PFS update  
which indicates a 12 Mtpa mine versus 
previous projections of 10 Mtpa whilst 
maintaining the same mine life
   first ore trucked from Pedra Branca to 
the Carajás East Hub and maintaining 
continuity of operations in Brazil whilst 
managing the high concentration of 
COVID-19; encouraging early drilling 
results received at Paes Carvalho and 
Santa Lúcia
   completion of the 270 km power 
transmission line to Prominent Hill via 
Carrapateena providing sufficient power 
for all new future regional expansions
   exceeding original budget expectations 
for metal production and group financial 
results (after adjustment for currency and 
metal prices), with a strong net profit after 
tax result of $212.6 million.
The value created for Shareholders in  
2020 included an annual share price 
increase of 79 per cent and dividends  
of 25 cents per share.
REMUNERATION OUTCOMES  
IN 2020
We believe the remuneration outcomes  
for 2020 are a good reflection of the 
Company performance and are aligned  
with the experience of shareholders.
Key remuneration outcomes for 2020:
   Executives’ salaries were increased as 
communicated in last year’s report, in line 
with our remuneration philosophy and 
supported by market data.
   Strong performance outlined above and 
in the Annual and Sustainability Report 
resulted in a Corporate Performance score 
of 4.2 out of 5. The details can be found 
in Section 3.2 (Table 6).
   Strong corporate and individual 
performances resulted in the award to 
the CEO, Andrew Cole, of 88.3 per cent 
of his maximum short term incentive (STI) 
opportunity; to the CFO, Warrick Ranson, 
of 88.0 per cent; and to CCO, Mark Irwin, 
of 87.3 per cent. 30 per cent of the 
STI will be paid in performance rights 
vesting after two years. STI outcomes are 
calculated after adjusting, where relevant, 
for the impact of changes in metal prices 
and currencies so that Executives do not 
receive windfall gains or losses for market 
related movements. Details can be found 
in Section 3.2 (Table 7).
   The 2018 long term incentive (LTI) plan 
vested at 100 per cent in December 2020 
following strong relative performance of 
the Company and strong absolute share 
price performance over the three year 
performance period. This resulted in the 
vesting of 130,285 performance rights for 
Andrew Cole; 51,300 for Warrick Ranson; 
and 51,300 for Mark Irwin. Details can be 
found in Section 3.3 (Table 10).
STAKEHOLDER VALUE CREATION
Our focus on value creation across all 
five Stakeholder groups – shareholders, 
government, communities, employees and 
suppliers – is a key differentiator for  
OZ Minerals and has been at the core of  
our Strategy since 2015. It is described 
more fully in the Governance section. We 
believe that we cannot create sustainable 
value for shareholders unless we also deliver 
accretive value for our other Stakeholders 
concurrently and in a complementary way.
We create financial value for shareholders 
by building the current and future income 
streams of the Company. We generate 
current income through the cost-efficient 
production and sale of concentrate from 
our operating mines. We build longer 
term value through creation of sustainable 
future income streams through the 
identification of additional resources at our 
current operations and in new projects, 
by developing deliverable plans for their 
profitable extraction and ultimately by their 
successful delivery and commissioning.

to $579,000 in September 2020
Note: Letter from the Chairman of People &  
Remuneration Committee is unaudited.
At the same time, we create value 
for our other Stakeholders in various 
complementary ways, for example, by 
reducing our environmental impact; by 
working respectfully with traditional owners 
of the lands on which we operate to protect 
their heritage and achieve their ambitions 
for their communities; by creating local 
employment opportunities; using local 
suppliers; and supporting our employees  
in their leadership development and  
work-life plans. 
For 2021 we will further embed our focus 
on Stakeholder Value Creation in the way 
we set our key performance indicators 
(KPIs) for STI awards for senior executives. 
We will move from KPIs to Stakeholder 
Value Creation Metrics and hold ourselves 
accountable for their achievement. Whilst 
not all the metrics will be financial in 
nature, all ultimately impact our financial 
performance. We will provide further 
transparency with our goals and our 
performance against those goals in  
our 2021 Remuneration Report.
REMUNERATION  
CHANGES FOR 2021
Other than the evolution of the approach  
to the measurement of performance for  
STI purposes outlined above, no changes are 
proposed to the remuneration framework 
for Executives in 2021. The Committee will 
continue to monitor whether the changes 
made in previous years are creating value 
and driving the right performance and 
cultural outcomes ahead of any further 
amendments. 
Following a benchmarking review of 
executive salaries against our stated 
remuneration positioning, the Board 
resolved:
   to increase the fixed remuneration of 
CEO, Andrew Cole, from $900,000 to 
$1,000,000 to bring him in line with 
peers of local and international mining 
companies of similar scale and complexity
   to increase the fixed remuneration of the 
CFO, Warrick Ranson, from $579,000 to 
$610,000 and of the CCO, Mark Irwin, 
from $559,000(a) to $600,000; both 
increases reflecting the critical role they 
play in value creation for the Company 
and their depth of expertise and talent 
at this important time in the Company’s 
growth. 
Further, in accordance with our 
remuneration framework in 2021,  
key management personnel (KMP) will  
be issued performance rights under a 
2021–23 LTI scheme.
As foreshadowed in our Remuneration  
Report last year, during the year, we 
undertook an independent review of Board 
fees. Following that review the Board 
determined that Board Chairman fees  
and Directors fees, which have not been 
increased since 2018, will be increased by  
9 per cent and 5 per cent respectively.  
People and Sustainability Committee Fees will 
increase by 5 per cent with no adjustment 
to Audit Committee fees. Changes to Board 
Fees and KMP remuneration took effect from 
1 January 2021.
The LTI scheme rules require the comparator 
group used to calculate the relative total 
shareholder return (TSR) to be reviewed 
annually for relevance. Following the review, 
two companies (Taseko Mines Limited and 
Central Asia Metals Plc) will be removed 
from the comparator group for the  
2021–23 LTI scheme and replaced with one 
new company (Nickel Mines) taking the  
total comparator group to 14 companies.
Finally, with effect from the 2019 LTI scheme 
and as previously advised, AISCs will form 
part of the measure for determining the 
vesting of LTI rights. Following a review of 
data providers, it has been decided to utilise 
the global rankings measured by CRU as the 
basis for determining relative performance. 
CRU’s global copper mine database and 
their ranking methodology is considered a 
more comprehensive and aligned measure. 
Whilst a challenging year in many respects, 
we are pleased that our commitment to 
value creation yielded strong returns for 
shareholders and other Stakeholders. We 
remain committed to the remuneration 
framework, believing that it is working 
in the interests of the Company and 
shareholders. It is driving performance and 
behaviors that we are proud of and creating 
value in both the short and long term.
Thank you for your ongoing support of  
OZ Minerals.

REMUNERATION 
OVERVIEW
REMUNERATION TO EXECUTIVE KEY MANAGEMENT PERSONNEL  
IN 2020
Full details of the audited cost to the Company of Executive KMP remuneration,  
calculated in accordance with the accounting standards and the Corporations Act 2001,  
are available in Table 12 of the Remuneration Report (page 67).
The table below (unaudited) which includes details of remuneration actually delivered 
to Executive KMP in 2020, has been prepared to be transparent with our shareholders 
regarding remuneration outcomes.
The uplift in the KMP remuneration received in 2020 is predominantly driven by the value  
of shares that vested through the 2018 Long Term Incentive Scheme. This outcome reflected 
the strong performance of the Company and the doubling of the share price over the three 
year period. Shareholders who were invested with the Company over that period have 
experienced the same share price growth.

(a)  This amount represents 70 per cent of total STI which was paid in cash for 2020. In addition, 30 per cent of total STI will be 
granted in performance rights, which vest after 2 years provided certain conditions are satisfied (refer Section 3.2). 18,029 
performance rights will be awarded to Andrew Cole, 7,706 to Warrick Ranson and 7,641 to Mark Irwin.
(b)  The value of the long term incentives which vested during the year is calculated by multiplying the number of performance 
rights vested by the volume weighted average price (VWAP) of $18.64 over the period 2 December to 31 December 2020. On 
31 December 2020, the 2018 LTI plan vested resulting in the award of 130,285 shares to Andrew Cole (see Section 3.3) and 
51,300 shares to each of Warrick Ranson and Mark Irwin. The performance rights were awarded on the basis of a VWAP (5 
trade days from 2 to 8 January 2018) share price of $9.21. The VWAP 20 trade days from 2 to 31 December 2020 at vesting of 
$18.64 demonstrates an increase of 102.4 per cent over the 3 year vesting period. 
(c)  Represents direct contributions to superannuation funds based on quarterly contribution limits under Super Guarantee Charge 
regulations. Amounts greater than the maximum superannuation level have been included in cash salary.

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 outperformance 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
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 stakeholder value creation.
Simplicity  
and equity
Performance  
and reward 
linkages
Market 
positioning and 
remuneration  
mix
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 Executives 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.

2.3 Remuneration framework
The OZ Minerals Remuneration Framework aims to attract great people to deliver the  
OZ Minerals Strategy, offering a fixed and variable (at-risk) pay that incentivises both short 
term and long term performance.
Element
Structure
Performance Measures
Total Fixed 
Remuneration 
(TFR)
Base cash salary  
and superannuation.
TFR is determined based on 
factors including external market 
benchmarking, relativity to peers 
and individual performance.
Short Term 
Incentive (STI)
Mix of 70 per cent 
cash and 30 per cent 
performance rights, 
with a two-year vesting 
period.
STI is determined based on 
performance against challenging, 
clearly defined and measurable 
corporate and individual 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 TSR  
70 per cent and AISC 30 per cent.
Link to delivery of corporate 
Strategy
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 Executives 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.
Minimum 
Shareholding 
Requirements 
(MSR)
All Executives 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 TFR.
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.
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 expectations, 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.

2.5.2 Total fixed remuneration (TFR)
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 the 50th percentile.
Changes from last year?
No changes to our approach to determine fixed remuneration were implemented in 2020 and none are 
proposed for 2021. 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.
2.5.3 Short term incentive (STI)
Why does the Board think  
an STI plan is appropriate?
Variable performance-based remuneration strengthens the link between pay and performance. The purpose 
of 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.
What are the performance 
conditions?
The performance conditions that determined STI outcomes in 2020 were: (a) Company KPIs, (b) Individual 
KPIs and (c) HWWT principles.
The Company KPIs in 2020 determined 80 per cent of the STI award for the Managing Director and CEO with 
individual KPIs determining the balance of 20 per cent. The Company KPIs determined 50 per cent of the STI 
award for the remaining KMP with the balance determined by attainment of individual KPIs (25 per cent) and 
the demonstration of behaviors exemplifying the Company’s HWWT principles (25 per cent).

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.
What is the value of  
the STI opportunity?
How is STI assessed?
   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.

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.
60
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 unvested remain on foot to 
vest in the normal course. 
How is the STI settled?
70 per cent of STI is paid in cash and 30 per cent of STI awarded in performance rights which vest, subject 
to fulfillment of conditions, two years after award.
Have the arrangements 
changed from last year?
No.
2.5.4 Long term incentive (LTI)
Why does the Board consider 
an LTI plan to be appropriate?
How is the award delivered?
Was a grant made in 2020?
What was the value  
of the 2020 grant for  
Executive KMP?
The Board believes that an LTI plan can:
   focus and motivate Executives 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 Executives, aligning them with shareholders by 
linking a substantial portion of their potential total reward to OZ Minerals’ shareholder returns.
The LTI is granted using performance rights under the OZ Minerals LTI Plan (detailed below). The 
performance rights have a three-year performance period. Post vesting they are subject to a two-year 
holding lock period.
A grant was made to all continuing participants in the LTI plan (Table 10, page 66), 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 (VWAP) of OZ Minerals as at the start of the performance period of $10.52. The performance 
period for the 2020 LTI grant is 1 January 2020 to 31 December 2022.

What are the performance 
conditions?
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 2020 are the same from 2019 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 relative 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.

Between 50th percentile and 75th percentile
Straight line vesting between 50% and 100%
75th percentile or above

The TSR performance hurdle accounts for 70 per cent of the LTI award. Grants in 2018 and 2019 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 CRU’s global copper mine database. The annual AISC performance 
will be recalculated across the full three-year period (total three-year absolute costs divided by total three-
year copper metal production). The comparison will be to the average published AISC benchmark across 
that same period. 
Performance in relation to this hurdle will be measured over the three-year performance period and will vest 
in accordance with the following table.
taBLe 3.6 – PerforManCe rights Vesting aCCording to aLL-in sUstaining Costs

Nil
50%
Between 50th percentile and 25th percentile (Lowest cost)
Straight line vesting between 50% and 100%
25th percentile or below
100%
The AISC hurdle accounts for 30 per cent of the LTI award. Prior to 2019, 30 per cent of the LTI award 
was subject to absolute share price growth over the performance period. Growth of 20 per cent or greater 
results in 100 per cent vesting. No rights vest at less than 20 per cent.
Service condition
In general, if executives cease employment as a ‘good leaver’ prior to vesting of their rights at the end of 
the performance period, a pro rata portion of their rights, having regard to the portion of the performance 
period that has elapsed, will continue on foot and be subject to their original terms as though they had not 
ceased employment. Any remaining rights will lapse immediately. Their shares still subject to a holding lock, 
will continue on foot and be subject to their original terms as though they had not ceased employment.
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 returns for shareholders.

What is the comparator 
group?
The comparator companies selected for the 2020 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?
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.
What happens in the event  
of a change of control?
In the event of a takeover or change of control at OZ Minerals, the Board has the discretion to determine 
that the vesting of all or some of the performance rights should be accelerated. If a change of control 
occurs before the Board has exercised its discretion, a pro rata portion of the performance rights will vest, 
calculated on the portion of the relevant performance period that has elapsed up to the change of control. 
The Board retains discretion to determine if the remaining performance rights will vest or lapse.
Is there any ability for  
the Company to ‘clawback’  
LTI awards?
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.
Does the Company have a 
policy in relation to margin 
loans and hedging at risk 
remuneration?
The Board can also adjust awards granted under the STI or LTI plans in the event that there is a catastrophic 
safety, environmental, or other event, in which an adjustment is warranted.
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?
No.

2.5.5 Minimum shareholding requirement
All Executives and certain senior management are expected to accumulate and hold a minimum level of vested shares in OZ Minerals over a 
reasonable period. Table 3.8 shows the extent of compliance.

(a)  Information at 31 December 2020 based on share price at that date. With expected levels of vesting of the deferred equity element of the STI and LTI, it is anticipated that all Executive KMP should 
meet their minimum shareholding requirement within the required timeframe.
(b)  Includes shares owned and vested and exercisable performance rights 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 2020, EY was engaged to undertake market benchmarking for the CEO’s remuneration and Guerdon Associates to undertake the 
market benchmarking for the NEDs. Their analysis was considered by the People & 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 fees for work conducted was respectively $10,000 and $26,542 (excluding GST).

(a)  EBITDA of $606 million exceeded the Plan EBITDA target, after flexing for commodity price and exchange, of $557 million (9 per cent above the target).
(b)  Metal volumes: Prominent Hill achieved full year underground production of 3.9 Mt ore whilst reducing unit costs and Carrapateena achieved its full year production of 2.93 Mt with a strong 
ramp up performance to 4.25 Mtpa from initial production early in the year. We assess this on CuEq basis. The criteria was ‘produce Plan volumes and achieve Carrapateena ramp up’ – which we 
exceeded.
(c)  Value creation in base and growth cases delivered across the business included: Prominent Hill commenced uplifting production from a 4 Mtpa Base Case to 4–5 Mtpa by 2022 through study for 
shaft haulage; Carrapateena has delivered an extremely strong, world-leading ramp-up and building long term value through expansion study which will expand production through a block cave to 
12 Mtpa; Pedra Branca decline progressed and first ore processed; and West Musgrave uplifted project value with the acquisition of Cassini Resources and an update of its initial study results which 
saw an uplift in NPV to $1.0 billion. The market reflected the increase in value of the assets of the business through an increase in the share price over the year.
(d)  The initial TRIF target of 5.50 improved 3.8 per cent, achieving a final TRIF of 5.29 on a rolling 12 month basis.

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 3.5 and absolute share price growth of the Company  
over the relevant performance period as detailed beneath Table 3.6. For 2018 LTI the TSR was assessed independently at 92.3 per cent  
and absolute share price had an increase of 121.01 per cent, resulting in full vesting of the Plan. For grants from 2019 onwards the  
vesting conditions are the relative TSR and AISC performance. In general, if executives cease employment as a ‘good leaver’ prior to vesting 
of their rights at the end of the performance period, a pro rata portion of their rights, having regard to the portion of the performance 
period that has elapsed, will continue on foot and be subject to their original terms as though they had not ceased employment. Any 
remaining rights will lapse immediately. Their shares still subject to a holding lock, will continue on foot and be subject to their original terms 
as though they had not ceased employment. 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 weighted average fair values were calculated proportional to the fair value of  each hurdle in the plan. 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 the 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)  Annual leave has been separately categorised and is measured on an accrual basis and reflects the movement in the accrual over the 12 month period. Any reduction in accrued annual leave 
reflects more leave taken/cashed out than that which accrued in the period.
(b)  Represents direct contributions to superannuation funds. Amounts greater than the maximum superannuation level have been paid and included in cash salary.
(c)  Represents the net accrual movement for Long Service Leave (LSL) over the 12 month period which will only be paid if Executive KMP meets the required service conditions.
(d)  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.
(e)  The fair 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
NED remuneration is reviewed annually by the Board. NEDs receive a fixed remuneration consisting of a base fee and additional  
fees for committee roles.
Consistent with best practice, NEDs do not receive any form of equity incentive entitlement, bonuses, options, other incentive payments

SUSTAINABILITY 
REPORT
OZ MINERALS2020 ANNUAL & SUSTAINABILITY REPORTsUstainaBiLit Y rePort

THEME 
The sustainability section of this report is presented 
around the theme of Creating Value for our 
Stakeholders. Creating Value has long been at the 
centre of OZ Minerals’ Strategy. However, this year  
we have developed a set of Stakeholder Value Creation 
Metrics to enable assessment of our performance. The 
Metrics provide transparency for our Stakeholders as 
to what we are measuring and how we are performing. 
They set the priorities and drive performance and 
behaviour within the Company. 
FORMAT
We have been reporting on our sustainability performance since 2008. In 2016, we  
began publishing our sustainability performance in a combined Annual and Sustainability 
Report to demonstrate the interconnectivity and interdependency of sustainability with 
company performance. It also enables us to integrate, across the whole report, the  
concept of creating value for our Stakeholders – shareholders, communities, suppliers, 
governments, and employees – which is at the centre of our Strategy.
Examples of this in practice are embedded throughout the report to reflect the integration  
of sustainability into our Assets and corporate functions, which we do through The OZWay,  
a simple model that explains how all the parts of OZ Minerals fit together. 
ORGANISATIONAL SCOPE AND BOUNDARY
We disclose sustainability data in accordance with the Global Reporting Initiative (GRI) 
and Sustainability Accounting Standards Board (SASB) Metals and Mining Sustainability 
Accounting Standard. Supporting documents that form part of our sustainability disclosures 
are available on our website. We have also developed our 2020 Sustainability Report 
Navigator Tool (ozminerals.com/sustainability) to make specific information more  
accessible via our website.
Our 2020 Sustainability Report covers the performance of our Australian Assets:  
Prominent Hill, Carrapateena and West Musgrave and our Brazilian Assets in the Carajás 
Province. These are facilities over which OZ Minerals had or gained operational control(a) 
during the 2020 calendar year. Joint ventures which we do not operate are excluded.
STAKEHOLDER ALIGNMENT WITH SUSTAINABILITY  
PERFORMANCE ELEMENTS
As creating value for our Stakeholders is at the centre of our Strategy, our 2020 
Sustainability Report shows how the elements of sustainability align with our  
Stakeholders. This year, we have also illustrated our alignment with select United  
Nations Sustainable Development Goals (SDGs) and discuss how our Company  
Strategic Aspirations align with specific SDGs.
ASSURANCE
OZ Minerals engaged KPMG to undertake Reasonable Assurance over our energy  
and emissions data for our Australian assets and Limited Assurance over selected 
information in this report. The full details of the process, scope of assurance and  
outcome are detailed in KPMG’s assurance statement on page 118-119.

STAKEHOLDER VALUE CREATION METRICS
The Stakeholder Value Creation Metrics were developed during 2020. The Metrics provide 
the reader, including our Stakeholders, with transparency on how we are creating value 
for our five Stakeholder Groups – employees, community, shareholders, government and 
suppliers – and the progress we are making. 
Stakeholder value creation is at the centre of our Strategy. Over the past two years, we 
have been embedding and systematising Stakeholder value creation into our governance 
processes so it is always part of how and what we do, and is not dependent on human 
drivers. For example, our Risk Specification impact table is structured around an assessment 
of the level of impact on each of our five Stakeholders. 
In developing the Stakeholder Value Creation Metrics, we provide transparency on 
our performance, and they also form the basis of our Company goals; thereby driving 
performance and behaviour in support of Stakeholder value creation within the Company.  
An assessment of performance against the Metrics shows where we are performing well and 
where we have scope for improvement. Our performance should be considered over time 
and in the context of the accompanying commentary, which we will publish annually.
It is only when we are creating value for all our Stakeholders that we will have a successful 
company delivering against our sustainability strategy and achieving our Purpose, ‘Going 
beyond what’s possible to make lives better’.

MATERIALITY ASSESSMENT
Our annual materiality assessment identifies the topics most important to our Stakeholders 
and our Performance. Outcomes of the materiality assessment allow us to better understand 
our context and inform the choices that drive delivery of our Strategy. 
We assess the importance of sustainability topics using two criteria: importance to our 
Stakeholders and importance to our business in terms of growth, economic and social 
impact. Material topics are discussed in this report and in the risk section of the Annual 
Report (page 40). Further information on sustainability is available on the OZ Minerals 
website (ozminerals.com/sustainability). 
UNDERSTANDING OUR STAKEHOLDERS’ INTERESTS: METHODOLOGY
We use a wide range of inputs to develop our assessment of what is material. These 
inputs include consultation with stakeholders, surveys of stakeholders, market intelligence, 
developments in operating jurisdictions, material Company risks, and internal reviews, 
including feedback from the Sustainability Committee. 
This year, 113 responses to our stakeholder survey were received from Australia and Brazil 
and across all five Stakeholder groups. The survey asked respondents what level of value 
each material topic had on their decisions to invest, take a job or partner with us, as well 
as the impact of our performance across the topics on them. The results of the survey are 
supplemented with analysis of media reports featuring OZ Minerals, which include the 
material topics. The survey and media analyses are further supplemented by analysis of 
industry trends among the material topics, for which we use industry risk reports, peer 
sustainability reporting and broader internationally recognised risk and sustainability 
insights, including the World Economic Forum’s Global Risk Report and the United Nations 
Sustainable Development Agenda. 
In 2020, 16 material topics were identified from the above process to reflect the different 
operating contexts of our Assets as a global business. We recognise that some topics  
are 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 from page 87 and cultural 
heritage, human rights and Land Connected and Indigenous Peoples are linked to our  
Social Performance (page 96).

SAFETY 
PERFORMANCE
High standards of 
leadership in the  
area of Safety for  
all Stakeholders.
Our target is to achieve an injury and 
occupational disease-free workplace 
by ensuring hazards are identified and 
managed at source.
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. 
We combine safety leadership with 
our governance framework, including 
the safety category of our Global 
Performance Standard which enable 
us to effectively manage material 
sustainability risks that are common 
across OZ Minerals. They set out for 
our workforce our minimum mandatory

Stakeholder Value Creation 
Metric: Total Recordable Injury  
Frequency Rate (TRIFR)
In 2020, the TRIFR rate of 5.29 per  
million hours worked represented  
an improvement of 30 per cent from  
the previous year’s TRIFR of 7.52*.
We have set a TRIFR target of 4.90 
(including Brazil) for 2021.
All safety incidents are thoroughly 
investigated, we share what we have 
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, through our real time Insights 
Hub. Our performance is monitored by our 
Executive 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 reduced 
as a result of active engagement from our 
senior leadership, and activities focused on 
identifying and eliminating the causes of 
incidents. The outcomes of investigations 
into significant incidents and incident trends 
are comprehensively reviewed by the Board’s 
Sustainability Committee to confirm that we 
learn from incidents, that there is a focus 
on compliance with approved processes, 
and that we implement additional controls 
where necessary. 
Safety statistics are calculated per one 
million working hours and inclusive of our 
Prominent Hill and Carrapateena mines 
in Australia, our Antas and Pedra Branca 
Brazilian operations, as well as facilities 
under OZ Minerals’ operational control, 
including the West Musgrave Project, 
exploration sites and our corporate offices.  
We continually monitor key indicators to 
track workplace incidents and injuries. 
Our governance framework includes 
the Learning Through Incidents Process 
Standard, which sets out the process 
for identifying, elevating and reporting 
incidents, including safety-related incidents. 
The Risk Management Process Standard, 
and its supporting Specification, is a critical 
Process Standard. Its five Stakeholder Pillars 
(shareholders, communities, suppliers, 
governments, and employees) Risk 
Specification Table supports the Learning 
Through Incidents Process Standard. 
Incidents and near misses are internally rated 
against potential or actual consequence 
and likelihood and assessed for their 
impact on our Stakeholders. This helps us 
identify significant incidents that warrant 
in-depth review and analysis. All actual and 
potential significant safety incidents are 
thoroughly investigated using the Incident–
Cause–Analysis Method (ICAM). Significant 
incidents are those deemed to have a high 
potential or actual serious consequence for 
our Stakeholders and include all recordable 
incidents and disabling injuries. 
2020 Safety Assurance  
Process update
To reflect our Employee Value Creation 
policy, OZ Minerals’ TRIF reporting 
methodology was updated in August 2020 
to include, where an incident is required 
to be reported, the associated work hours 
(Exposure Hours) in the TRIF rate calculation. 
All data reported from 1 January 2020 
was retrospectively adjusted to align with 
the updated methodology. Incidents and 
Exposure Hours associated with remote 
work in line with the Company’s move to 
more flexible work (i.e. working from home) 
and OZ Minerals-controlled business travel 
are now both included in the TRIF rate 
calculation.
Case Study: Insights HubAn OZ Minerals Strategic Aspiration is that We use data and technology for tactical decision making, repetitive work and to improve safety, allowing our people to focus on complex and innovative thinking. To inform our safety choices and proactively identify material trends in 2020, OZ Minerals developed an ‘Insights Hub’ that brings key datasets from all assets into a single platform to help us optimise data-based decision making. These data have the ability to provide rigorous scenario analysis to inform data-driven decisions for all elements of our Assets.84
CONTRACTOR MANAGEMENT
Stakeholder Value Creation 
Metric: Zero fatalities
In 2020 there were no fatalities within  
our direct and contractor workforces. 
Our projects are delivered in collaboration 
with contractors and suppliers, as we 
rely in part on their capabilities in the 
management of our operations. All contract 
partners must meet OZ Minerals’ Global 
Performance Standards and our Global 
Process Standards define the requirements 
and practices for working with contractors 
and suppliers. Major contractors are 
contractually obliged to comply with 
our Code of Conduct, relevant Value 
Creation Policies, standards and local level 
agreements. Contractors must respect our 
HWWT Principles 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, social and environment) and 
performance criteria (including operating 
performance and site management) are 
developed and applied to our contracts.
SAFETY PROGRAMS
We are committed to protecting the 
safety of our employees, suppliers and 
communities. We actively collaborate with 
all Stakeholders to prevent work-related 
injuries, incidents and illnesses. In 2020, in 
response to our changing context due to 
COVID-19, and flexible work, we introduced 
a number of initiatives to mature our 
safety culture with a focus on safety and 
wellbeing programs. Leadership plays an 
important part in our safety culture through 
demonstrating and promoting safety in 
our workplaces. 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 Global 
Performance Standards and identifying 
opportunities for continuous improvement 
through our risk management Process 
Standard that is centred around impacts  
on our Stakeholders.
Effective safety management means we: 
   take a risk-based approach to decision 
making based on impacts to OZ Minerals 
and our Stakeholders
   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.
Case Study: Prominent Hill Underground Mining  Services ContractIn 2020, the Prominent Hill Underground Mining Services Contract was awarded to Byrnecut Mining Services under an alliance contract model. A partnering approach was taken to inform the development and co-management of the Alliance. The Alliance model provides a platform and process for value creation, by structuring collaboration between the project teams to deliver alignment on measurement, and to set the priorities to drive performance and the behaviors within the Asset to optimise safety, production, environment and social performance.OZ MINERALS2020 ANNUAL & SUSTAINABILITY REPORTsUstainaBiLit Y rePort

TRAINING AND EMERGENCY 
PREPAREDNESS
We continuously explore and adopt 
methods to ensure we grow the capability 
of our leaders and employees. Our Crisis 
Management Plan outlines the roles, 
responsibilities and processes that our 
corporate Crisis Management Team (CMT) 
would follow during a crisis event. 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 CMT. We hold 
regular emergency exercises, both desktop 
and practical, to test our emergency 
preparedness. 
Case Study: Crisis Management Team  At the onset of the COVID-19 pandemic, OZ Minerals activated our CMT in accordance with our Crisis Management Plan. The CMT is chaired by the CEO and includes representatives from operations, legal, commercial, safety, environment, community, communications and government relations. The CMT met multiple times per week over the course of the pandemic to evaluate the public health risk and coordinate our response in line with government restrictions in Australia and Brazil. Our sites quickly reduced onsite workforce to critical roles only, minimising the movement of people to and from the sites and within the community. Each site established disease transmission prevention protocols including travel pre-approvals, health screening, physical distancing, single-serve food, and onsite testing capabilities to minimise the risk  to those remaining on site.Case Study: Pedra Branca Underground Mine Development The Pedra Branca mine under construction is one of the only underground mines in the Carajás region of northern Brazil. In 2020, new Refuge Chamber Technology was installed that contains the ability to monitor occupants within the chamber closely during an emergency on site. When activated, the cameras send a live, recorded  stream of both the interior and exterior of the refuge chamber.86
ENVIRONMENTAL 
PERFORMANCE
Minimising our impact 
and caring for the 
natural environment.
We understand that how we manage 
our impact on the natural environment 
can directly, indirectly, or cumulatively 
impact our Stakeholders, in particular 
the values and livelihoods of our host 
communities and Land Connected 
and Indigenous Peoples. In 2020, 
we increased our focus on climate 
change and emissions, with significant 
progress made on implementing the 
Task Force on Climate-related Financial 
Disclosures (TCFD) framework. We have 
also increased our efforts regarding 
management of tailings storage facilities, 
in line with developments in industry 
standards and Stakeholder expectations. 
Reducing our emissions, water usage and 
waste generation to optimise our assets 
and reduce our impacts on Stakeholders 
are key areas for OZ Minerals that are 
supported by our Strategic Aspirations.

Stakeholder Value Creation 
Metric: Scope 1 & 2 absolute 
emissions
There was a slight decrease in Scope 1 
emissions (~1,800 tCO2-e) at our Australian 
assets and a small increase in Scope 2 
emissions (~11,500 tCO2-e). Our overall 
Scope 1 and 2 emissions footprint is higher 
in 2020 as we have included emissions from 
our Brazilian assets for the first time. 
Overview
We are a copper-core modern mining 
company providing a metal that is central 
to the transition to a low carbon economy. 
Where practicable, we use underground 
mining methods at our Assets which are 
currently less emissions intensive than open 
pit operations and provide a wider range 
of opportunities for emissions reduction. 
We seek to conduct our activities socially, 
ethically and in an environmentally 
responsible manner. Our operating assets 
in South Australia are connected to a grid 
that is forecast to reach 100 per cent net 
renewable energy by 2030 (currently circa 
56 per cent). Electricity used by our Brazilian 
Assets is already over 80 per cent renewable. 
Our West Musgrave Project maintains 
an ongoing commitment to an off-grid 
renewable power solution with a future 
focus on developing a roadmap to 100 per 
cent renewable electricity generation and 
reducing dependency on fossil fuels.
In 2020, we continued our focus on 
incorporating climate change opportunities 
and threats into our Strategy and business 
planning. We released 18 Strategic 
Aspirations which include emitting zero 
Scope 1 emissions and systematically 
reducing Scope 2 and 3 emissions. These 
Strategic Aspirations are supported by our 
Acceleration Priorities. In this year’s Annual 
and Sustainability Report, we released our 
Stakeholder Value Creation Metrics – which 
include energy and emissions – to illustrate 
our performance against our Strategy. 
We continued to deliver against our TCFD 
Action Plan, building on commitments made 
in 2019 to implement the framework. As 
outlined in the Action Plan, implementing 
the TCFD framework is a multi-year process. 
The following sections outline our progress 
against the TCFD categories in 2020. 
Stakeholder Value Creation 
Metric: Net energy intensity  
(per t Cu Eq) 
Energy intensity is similar across our assets, 
ranging from 16 to 18 GJ per t Cu Eq.  
Our overall group energy intensity is  
16.8 GJ per t Cu Eq.
Stakeholder Value Creation 
Metric: Scope 1 & 2 emissions 
intensity
Combined Scope 1 and 2 emissions 
intensity is fairly consistent across our 
assets, ranging from 1.4 tCO2-e per t Cu Eq 
to 1.7 tCO2-e per t Cu Eq.
Stakeholder Value Creation 
Metric: Renewable energy 
percentage
Our Assets are in jurisdictions with  
high renewable penetration, particularly  
in Brazil where over 80 per cent of  
grid electricity is renewable. Our  
South Australian assets operate on  
57 per cent renewable energy.

Governance 
The Board Sustainability Committee, 
which met quarterly in 2020, maintains 
oversight of material sustainability risks 
(both opportunities and threats), including 
climate change. The Committee also 
supports the Board by maintaining oversight 
of strategy, governance and compliance 
relating to sustainability matters. In addition, 
the Committee monitors trends and 
developments in legislation and regulation 
(refer to Governance Section of the Annual 
and Sustainability Report, page 26).
Management implements OZ Minerals’ 
Governance structure and Risk Management 
Framework, which encompasses 
opportunities and threats associated 
with climate change. To further support 
management’s role in assessing and 
managing climate-related risks, a ‘deep dive’ 
was undertaken in 2020 with the Executive 
Leadership Team, led by the Group Manager 
Government Relations & Climate. The deep 
dive was designed to build understanding 
of physical and transition risks, and the 
context in which these are managed 
for OZ Minerals’ global business. Senior 
management also participated in a series of 
dedicated asset and project climate-related 
opportunity and threat workshops (see 
Strategy and Risk Management below). 
Strategy
The global energy system is shifting as 
the world decarbonises. Copper is an 
essential enabler of this transition as a 
core component of electric mobility and 
renewable energy, as well as the networks 
which connect them. As a modern mining 
company with a copper focus, we provide 
this critical element of the low carbon 
transition. Our Stakeholders are increasingly 
focused on sustainable production of copper 
and we are well placed to continue to meet 
these expectations.  
88
In 2020, OZ Minerals released our Strategic 
Aspirations and Acceleration Priorities. 
Climate change issues served as a key input 
in this process, resulting in our Aspirations 
to emit zero scope 1 emissions and strive 
to systematically reduce scope 2 and 3 
emissions across our value chain, strive 
to minimise water use and adding value 
when we do and consume and produce 
in a way that generates zero net waste 
and creates value for Stakeholders. These 
Aspirations are supported by Acceleration 
Priorities including reducing high-emissions 
energy use and baselining our Scope 3 
emissions.
CLiMate-reLated oPPortUnities  
and threats
As outlined in the Risk Management 
section of our TCFD disclosures, dedicated 
workshops were conducted with our 
Australian assets and projects to assess 
climate-related opportunities and threats 
in line with OZ Minerals’ Risk Management 
Framework. Assets and projects have 
developed specific controls and actions to 
progress the opportunities and manage the 
threats to suit their context, in line with 
the devolved operating model and Risk 
Management Framework.
sCenario anaLYsis
In 2020, we began scenario analysis with 
our Australian Assets, Prominent Hill and 
Carrapateena, to conduct assessments of 
physical climate-related risks. Assessments 
were based on a high-warming climate 
change scenario consistent with ~4°C above 
pre-industrial levels by 2100, with a ~2°C 
warming scenario used to test sensitivity. 
Specifically, climate change scenarios  
were developed using several inputs:
   Intergovernmental Panel on Climate 
Change (IPCC) Assessment Report 5 (AR5) 
Representative Concentration Pathways 
(RCPs) as a basis. In particular RCP 8.5  
and RCP 4.5. 
   The CSIRO’s Australian Climate Futures 
tool was used to project changes in 
climate variables (e.g. temperature, 
rainfall, extreme rainfall, solar radiation, 
etc.) at a scale relevant to OZ Minerals’ 
Australian assets.
   The results of the Climate Futures 
Tool were further supplemented with 
projections from the SA Climate Ready 
project, which provides dynamically 
downscaled climate projections for South 
Australia across six regions. Projections for 
the SA Arid Lands and Alinytjara Wilurara 
and Northern and Yorke regions are 
relevant to OZ Minerals.
Given the limited divergence between 
climate change scenarios over the next 
10–20 years, timeframes were not limited to 
current life of mine, but more appropriately 
reflective of life of province.
oPPortUnities – redUCing greenhoUse 
gas eMissions (transition)
Opportunities to reduce GHG emissions 
identified by OZ Minerals’ Assets and 
Projects included:
Intense rainfall events
   Potential impacts: Site access for supplies 
and shipment of product, direct impacts 
to infrastructure and operations, increased 
infrastructure maintenance requirements.
   examining options to increasingly  
   Mitigating controls: Reviewing road 
design specifications and maintenance 
arrangements to consider future extreme 
rainfall predictions, review of site 
drainage infrastructure, review supply 
chain inventory management considering 
potential for disruptions, consideration of 
potential extreme rainfall events in TARPs.
Risk Management 
Climate change has been identified as 
a strategic risk (both opportunities and 
threats) by OZ Minerals since 2017. In 
2020, a series of dedicated workshops 
with operational personnel and senior 
management were conducted with  
OZ Minerals Australian Assets and projects 
to Assess climate-related opportunities  
and threats in line with OZ Minerals’  
Risk Management Specification. In 2021, 
this work will be undertaken across all  
OZ Minerals’ Assets and projects. 
Risk assessment workshops provided a 
platform to build understanding of climate-
related risk in the context of the individual 
Assets. Threat workshops utilised scenario 
analysis based on IPCC AR5 (refer to 
Strategy section of our TCFD disclosures), 
while opportunity workshops focused 
on identifying greenhouse gas reduction 
initiatives to support OZ Minerals’ Strategic 
Aspirations. 
Consistent with OZ Minerals’ Risk 
Management Specification, climate-related 
risks (opportunities and threats) are captured 
in Asset and project risk registers. Controls 
and actions are captured against each risk, 
with regular review of progress. Risks are 
also reviewed regularly. 
As part of a review of OZ Minerals’ suite 
of Global Performance Standards in 2020, 
several Environment Performance Standards 
were updated to include considerations 
relating to assessment and management of 
climate-related threats and opportunities. 
Our Global Performance Standards enable 
us to effectively manage the material threats 
and opportunities that are common across 
OZ Minerals. The Standards apply to our 
employees, directors, officers, contractors, 
consultants, and any other party when 
undertaking work for or on behalf of  
OZ Minerals.

Change (PhYsiCaL)
Scenario analysis revealed extreme summer 
temperatures and intense-rainfall events 
to be the key potential climate-related 
physical impacts for Prominent Hill and 
Carrapateena. These impacts are managed 
as components of broader extreme weather 
threats by our Assets which maintain a 
suite of controls to reduce the impact. The 
threat of extreme weather was rated as 
Material for the Company according to the 
Risk Management Specification. Consistent 
with our risk management processes, re-
assessments are undertaken on a regular 
basis to capture changes in operations  
and climate over time.
The potential impacts and mitigating 
controls for extreme heat and intense  
rainfall events include:
Extreme heat
   Potential impacts: Employee safety 
(heat exposure), plant and equipment 
operation, power supply reliability, 
potential flight payload restrictions.
   Mitigating controls: Working in 
thermal conditions health and safety 
protocols, increased cooling capacity for 
underground ventilation, Trigger-Action-
Response-Plans (TARPs) and design 
specifications and standards to include 
predicted temperature increases.

Metrics and Targets
In 2020, we released our Stakeholder Value Creation Metrics which illustrate how we create value for our Stakeholders in line with our 
Strategy, building on our existing disclosures. We established a broader suite of metrics on which our Assets report monthly, including 
metrics associated with climate-related issues. These metrics complement our Strategic Aspirations and Acceleration Priorities released 
in 2020. As outlined in the Strategy section of our TCFD disclosures, our Strategic Aspirations and Priorities include emitting zero Scope 
1 emissions, striving to systematically reduce Scope 2 and 3 emissions across our value chain, minimising water use and consuming and 
producing in a way that generates zero net waste.

Case Study: Australia’s first battery powered  
vehicle for underground explosive charging
As part of realising our Strategic Aspirations, Carrapateena is committed to 
investigating various technologies and strategies to reduce GHG emissions at site. 
This commitment has seen the Asset trial a variety of electric vehicles in 2020, one of 
which is the Charmec MC 605 VE SmartDrive. It is Australia’s first battery-powered 
zero emissions vehicle for underground explosive charging. This has complemented 
the ongoing Zero Automotive partnership that is developing the ZED70 Ti electric light 
vehicle. The new, street-legal ZED70 Ti includes a specifically selected Li-Ion battery 
chemistry, battery housing, control systems and charging capability to endure the  
hyper saline underground environment at Carrapateena.

WATER
* Water stress as defined by the World Resources Institute 
Aqueduct Water Risk Atlas.
AIR QUALITY
Stakeholder Value Creation 
Metric: Water consumed per 
tonne copper equivalent  
In 2020, our Australian assets consumed 
between 0.06 and 0.08 ML per t Cu Eq. 
Carrapateena recycled 59 per cent of water, 
while Prominent Hill recycled 22 per cent.
Water is an essential component for our 
operations and a resource our Stakeholders 
rely on. Each of our assets and the context in 
which they operate is unique. As such, they 
independently monitor and work to optimise 
the net water consumed per equivalent 
copper tonne, conscious of the need to 
protect life on land and to responsibly 
consume a critical and potentially shared 
resource. We recognise the need to manage 
our use of water and have incorporated 
this in our Strategic Aspiration to strive to 
minimise water use and add value when  
we do. 
Our Australian assets, Prominent Hill and 
Carrapateena, are located in arid areas 
and are dependent on groundwater to 
sustain operations. Groundwater wellfields 
at Prominent Hill are located on nearby 
pastoral stations, where pastoralists draw 
water from shallower or discrete aquifers in 
the majority of cases. Carrapateena utilises 
hypersaline water that is not suitable for 
pastoral activities. 
This hypersaline water is processed via a 
reverse osmosis water treatment plant to 
provide potable water. The Carrapateena 
Tjungu Camp provides treated greywater 
suitable for livestock consumption to the 
local pastoralist to add value to the pastoral 
operations. 
Our water monitoring program involves 
measuring and monitoring water levels and 
quality in previously agreed pastoral wells, 
as well as conducting sediment monitoring, 
including metal concentrations and 
acidity, to detect any potential changes in 
downstream surface water quality. 
Our Carajás Hub Assets in Brazil are 
situated in a region with a high annual 
rainfall of over 1,800 mm. Our Antas 
mine in the Carajás manages a Water 
Resources Management Program which 
aims to monitor and evaluate surface and 
groundwater. 
Stakeholder Value Creation 
Metric: Water withdrawal in areas 
of extreme water stress (%)
No OZ Minerals assets withdraw water  
in areas of extreme water stress.*
Dust is among the largest air quality 
emissions from the majority of our 
operations, generated by stockpiling 
materials and vehicles moving over 
unsealed surfaces. All assets monitor 
and manage air quality via an Air Quality 
Management Plan as per the Air Emissions 
Performance Standard. As our operations 
transition to underground, our dust 
impacts have reduced. Control measures 
to reduce the amount of dust we generate 
include active dust suppression on roads, 
speed restrictions, and regular road 
maintenance. Sampling verifies that our 
air quality management has effectively 
mitigated adverse impacts on workers, 
the community and the environment at 
Prominent Hill, Carrapateena and Carajás 
Province. There are no ozone-depleting 
substances, persistent organic pollutants or 
stack emissions produced at these Assets. 
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. 
92
WASTE AND TAILINGS
Stakeholder Value Creation 
Metric: Non-mineral waste 
produced per tonne of copper 
equivalent 
Non-mineral waste intensity across our 
assets ranges from 0.02 t per t of Cu Eq to 
above 0.1 t per t Cu Eq. Generally waste 
intensity is higher at newly constructed 
assets as more materials are utilised in 
bringing the operation to production.
OZ Minerals has active tailings facilities 
at Prominent Hill and Carrapateena in 
Australia, and at the site of the Antas 
mine in the Carajás East Hub in Brazil. The 
Carajás East Hub also processes ore from 
the Pedra Branca satellite mine. In line with 
our Global Performance Standards, in 2020 
all tailings facilities underwent inspections 
by independent geotechnical engineering 
specialists with experience in the design, 
operation and auditing of tailings dams. The 
results of inspections were reported to the 
Board Sustainability Committee.
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. 
Carrapateena ramped up to reach a mine 
production rate of 4.25 Mtpa during 
November 2020, following achievement of 
the milling nameplate rate in March 2020. 
The Carrapateena Mine Stage 1 TSF is a 
cross valley starter embankment. The initial 
lift (Stage 2) has been constructed using 
a downstream raise methodology with 
similar construction materials to 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 mine TSF embankment has been 
raised only once using the downstream 
construction method.
Our Tailings Global Performance Standard 
applies across the Company and sets 
out our approach to managing tailings 
within the TSFs. The Standard is written 
to ensure TSFs are designed, constructed 
and managed to provide for the safe, 
long term impoundment of mine tailings 
and residues to prevent uncontrolled 
releases and seepage to groundwater. We 
conduct groundwater sampling to monitor 
parameters such as depth to water, salinity, 
pH, and metal concentrations as part of 
our tailings management. OZ Minerals’ 
Australian TSFs have been designed, 
constructed and operated in accordance 
with ANCOLD (Australian National 
Committee on Large Dams) requirements. 
In Brazil, quality assurance and monitoring 
activities are undertaken as normal course of 
business with bi-monthly reporting provided 
to the Mines Department (ANM).
We are currently completing reviews of 
our Tailings Global Performance Standard 
and are considering the recently-published 
Global Industry Standard on Tailings 
Management as part of that review.
No potential acid-forming (PAF) material  
was mined at Prominent Hill or Carrapateena 
over the reporting period, with the Assets 
producing 3,483,354 tonnes and 1,574,528 
tonnes of waste rock, respectively. Most 
of the waste rock generated is placed in 
rock dumps, with a proportion of non-
acid forming (NAF) rock used to construct 
mine infrastructure, such as the TSF 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. 
Case Study: Commissioning of Prominent Hill Malu Paste PlantThe management of mine tailings has been associated with significant safety incidents globally impacting stakeholders. In 2020, Prominent Hill commissioned the Malu paste plant to utilise this waste stream as a valuable resource to support the mining process by using it in underground mining areas that require backfilling. This utilisation of tailings as a substitute has reduced reliance on the Prominent Hill TSF, reducing risks for all stakeholders associated with storage, management, closure and licensing.OZ MINERALS2020 ANNUAL & SUSTAINABILITY REPORTsUstainaBiLit Y rePort

LAND AND BIODIVERSITY
Stakeholder Value Creation 
Metric: Area (ha) disturbed in 
high biodiversity conservation 
areas
No land was disturbed in high biodiversity 
conservation areas at our Assets during 
2020.
OZ Minerals has established and continues 
to manage Significant Environmental Benefit 
(SEB) offset areas at our Prominent Hill and 
Carrapateena mines. The SEB offset areas 
support habitat by managing threatening 
processes during operations and restoration 
of selected onsite areas cleared to enable 
mining activities. Flora and fauna monitoring 
of the SEB offset area at Prominent Hill 
has been continuously 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. At 
Carrapateena, the nationally threatened 
Plains Mouse occurs within the project area, 
while 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 mine. In the Carajás region, 
our teams have cultivated a nursery to 
support the maintenance of local biodiversity 
and revegetate disturbed areas.
Case Study: Plains Mouse Motion Capture In 2020, OZ Minerals Carrapateena established a low impact, year-round surveillance for the nationally protected species, the Plains mouse. The project is a partnership between OZ Minerals, engineering consultancy Jacobs and our pastoralist neighbours  at South Gap Pastoral Station. Camera traps were set up at eight locations in the Northern SEB offset. Each location featured a night-active motion sensor camera and a bait to attract the Plains mouse and any other small marsupials or larger mammals. The aim of this first phase was to gain a greater understanding of the gilgai habitat while also gathering data on Plains mouse populations in the area. This project involved a high level of collaboration with ecologists and landowners and will provide a greater understanding of Plains mouse distribution in a broader regional sense. The OZ Minerals detection methodology, which aligns to objectives within the National Recovery Plan, has been revised to provide a more accurate understanding of population response dynamics following large rain events which are the catalyst for boom cycles.94
REHABILITATION  
AND CLOSURE
The potential social and environmental 
impacts of mine closure are considered 
throughout mine life through regular 
engagement with Stakeholders. To further 
understand these impacts and identify 
new opportunities, OZ Minerals joined 
the Cooperative Research Centre for 
Transformations in Mining Economies 
(CRC TiME) in 2020. CRC TiME brings 
together over 70 leading mining and mining 
service companies, regional development 
organisations, State and Commonwealth 
governments and research partners. 
This unique coalition brings scale and 
coordinated investment into innovative 
research that addresses the complex 
challenges associated with mine closure  
and relinquishment.
OZ Minerals’ South Australian operations 
have documents and programs detailing 
closure, including the Supporting Works 
Plan and the Programs for Environment 
Protection and Rehabilitation (PEPRs). 
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, and 
progressive rehabilitation is undertaken 
where possible. At Prominent Hill, a 
mature mine, rock armouring of the North 
Waste Rock Dump has been completed 
and the rock armouring of the South 
Waste Rock Dump is nearing completion. 
Rock armouring of the TSF is 85 per cent 
complete. 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.
Case Study: Cooperative Research Centres (CRC) Transformation in Mining Economies (TiME) CollaborationA Life of Mine plan for resource extraction can effectively integrate progressive closure and rehabilitation into mine development, expansion and operation while retaining the opportunity to create a ‘second life’ for assets. OZ Minerals is partnering with Cooperative Research Centres for Transformation in Mining Economies (CRC TiME) which brings together over 70 partners across all stakeholder groups to help inform  our closure and rehabilitation planning and processes. In December 2020, OZ Minerals in conjunction with CRC-TiME, Adelaide University, University of South Australia and the University of Western Australia held workshops to collaborate on opportunities to build these concepts into the scopes for the Prominent Hill Expansion (PHOX) study  and Carrapateena Expansion (CarraX) study.OZ MINERALS2020 ANNUAL & SUSTAINABILITY REPORT95

of our Stakeholders informs our Choices 
and how we can create value. We 
understand that every stakeholder, 
context and host community is unique. 
Our Risk Management Specification 
considers opportunities and threats and 
focuses our decisions on the impact 
of our actions on our Stakeholders. 
Our Global Performance Standards set 
out our minimum mandatory control 
requirements, encourage co-development 
with Land Connected and Indigenous 
Peoples and other Stakeholders. They 
also provide processes to ensure all 
decisions are underpinned by Free Prior 
and Informed Consent (FPIC).

Stakeholder Value Creation 
Metric: Number and average 
duration for resolution of 
concerns, complaints and 
grievances
We recorded two complaints in our 
Stakeholder Management System for 2020. 
The average resolution time was 7 days.
We seek to build and maintain strong, 
transparent, supportive relationships with 
all Stakeholders. We operate in host and 
local communities based on the principles 
of quality contact, and procedural and 
distributional fairness. Our Assets have 
Stakeholder engagement programs based 
on sustained, ethical and context specific 
engagement processes with regulatory 
bodies, suppliers, government agencies, 
communities, Land Connected and 
Indigenous Peoples on which we may have  
a direct, indirect or a cumulative impact. 
We understand our activities will have 
an impact and each host community has 
unique knowledges, experiences, histories 
and values. Our approach is to work 
collaboratively to identify shared aspirations 
and benefit from our activities. Working this 
way ensures collaboration, input and co-
design from local Stakeholders and provides 
the opportunity for us to understand 
the environmental, social and economic 
implications of our work, and minimise 
adverse impacts. We also engage with key 
special interest groups and stakeholders 
who may potentially be affected by Asset 
activities to better understand stakeholder 
values and 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. Our Global 
Performance Standards require culture 
and context specific mechanisms to be 
in place, to capture feedback, concerns, 
complaints and grievances so they are 
promptly and appropriately addressed. 
Our Asset local level agreements contain 
no clauses restricting Stakeholders’ rights 
or ability to escalate concerns. Our Asset 
general managers have structured and 
direct relationships with Land Connected 
and Indigenous Stakeholders. Each Assets’ 
community relations function monitors 
and reviews major communication and 
consultation activities to assess their 
effectiveness and promote internal and 
external stakeholder feedback.
Case Study: Stakeholder Engagement How we engage and maintain our stakeholder relationships is important to us.  In 2020, OZ Minerals hosted visitors to our Prominent Hill site from the Woomera Prohibited Area (WPA) Advisory Board. The WPA Advisory Board provides guidance around coexistence arrangements in the WPA and is supported by the relevant Commonwealth and South Australian Government agencies.98

Partnering has been an element of  
OZ Minerals’ Strategy since 2019. We 
believe Partnering provides us a process 
by which we can collaborate and draw 
upon expanded skills and competencies for 
mutual benefit enabling us to create value in 
different contexts with diverse Stakeholders.
In 2020, developing a partnering framework 
for application across the Company was 
identified as an Acceleration Priority. The 
focus on partnering follows successful 
partnerships established with Traditional 
Owner groups at Prominent hill and 
Carrapateena, and the partnership with 
Global Maintenance Upper Spencer Gulf 
(the local industry body).
As each community and Asset is unique,  
a comprehensive understanding of the 
history, knowledge systems, world views, 
values, beliefs and experiences of host 
communities is required to underpin 
ethical, respectful, inclusive and effective 
engagement. At our Prominent Hill and 
Carrapateena Assets, the general managers 
have a direct, structured, regular and 
sustained liaison with Traditional Owners. 
Our current Brazilian Assets’ workforces 
reside locally and are not located in 
areas occupied by Land Connected and 
Indigenous Peoples. The requirements 
regarding engagement with Land Connected 
and Indigenous Peoples are set out in the 
OZ Minerals Land Access, Acquisition and 
Resettlement Global Performance Standard. 
In line with the Standard, each asset must 
operate in accordance with the principles of 
the United Nations Declaration of the Rights 
of Indigenous Peoples (UNDRIP). 
In Australia, we recognise and respect the 
unbroken cultural connection and cultural 
authority of Aboriginal and Torres Strait 
Islander Peoples. Our value creation and 
partnering approach is based on our ability 
to ensure all decisions are underpinned by 
FPIC, equity, transparency, reciprocity, and 
respect. Partnering has provided us with a 
process to collectively build sustained mutual 
respect and knowledge to deliver genuine 
partnerships with our Traditional Owners. 
Partnering has enabled relationships 
underpinned by trust, transparency, ethical 
listening, respect and integrity. It allows 
us to build a common understanding 
and language, identify opportunities and 
continually learn from each other to work 
towards shared goals. 
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. 
Our commitment is enshrined in our 
partnering agreements that inform the 
management of our production Asset 
specific Native Title Mining Agreements.

Case Study: Tjunguringanyi (working together) Antakirinja Matu-Yankunytjatjara Aboriginal Corporation (AMYAC) and OZ Minerals Prominent Hill’s Native Title Mining Agreement (NTMA) was established with the Antakirinja Matu-Yankunytjatjara Aboriginal Corporation (AMYAC) in 2006. Since then, the goals and aspirations of AMYAC and OZ Minerals have evolved significantly. This passage of time prompted a re-examination of our Agreement in early 2019 to ensure it is fully realising the mutual benefits of mining through collective commitment and investment. A three day ‘health check’ workshop was held to share lessons from the past, our mutual aspirations, and agree on how to best achieve our goals. The process that emerged from the health check was Tjunguringanyi or ‘Working Together’. The health check workshop was attended by the AMYAC Board, senior community members and OZ Minerals’ CEO and executive team members. We have now developed a shared vision and values that have become the benchmark for how we work together. They shape our expectations for how we operate at Prominent Hill and promote a diverse and inclusive workplace for AMYAC workers  and Indigenous employees more broadly. Tjunguringanyi has enabled an increase in Indigenous employment at Prominent Hill, from five per cent in 2018 to more than 9 per cent in December 2020. The shared values of Tjunguringanyi are:  Kulini – listening to each other   Ngarpartji Ngarpartji – reciprocity   Kunpun – sustainability  Nintiringanyi – making informed decisions.Tjunguringanyi is centred around our collectively agreed values illustrated in the graphic above, and functions with structured meetings held quarterly with the leaders of each organisation. This process has contributed to a much deeper understanding of each organisation’s values and of the impacts of our actions. Open honest and transparent dialogue has challenged assumptions and broken barriers that have been critical in maintaining and enhancing how we work together during the disruption of COVID-19.In 2020 the Antakirinja Matu-Yankunytjatjara Aboriginal Corporation (AMYAC) and OZ Minerals were jointly recognised and received the Premiers Award for Energy and Mining for Community – See short video youtube.com/watch?v=tdSTiV-plI4100
CULTURAL HERITAGE
Stakeholder Value Creation 
Metric: Unauthorised cultural 
heritage breaches/significant 
environmental and social 
incidents
In 2020, we did not record any 
unauthorised cultural heritage breaches 
or significant social or environmental 
incidents at our operations
We recognise that cultural heritage is 
the endowment that each generation 
receives and passes on. We understand 
the fundamental role the respect and 
preservation of culture and heritage plays in 
how we partner with Land Connected and 
Indigenous Peoples in Australia and globally. 
We understand that in many contexts, the 
land and natural resources with which we 
interact are tied to the Land Connected 
Peoples’ culture and can be the basis of all 
social identity and development. 
When developing local level agreements to 
enable resource extraction, we consider that 
protecting and managing cultural heritage 
assets jointly with communities contributes 
to the quality of our relationships and 
is a foundation for creating value for all 
stakeholders. 
Our Cultural Heritage Global Performance 
Standard requires all Assets to work with 
Land Connected and Indigenous Peoples 
to proactively respect and protect heritage. 
At all stages of our project development 
lifecycle, we seek to collaborate and partner 
with Land Connected and Indigenous 
Peoples to co-develop the Asset footprint 
and fit for purpose cultural heritage 
management plans and awareness training. 
Cross-cultural awareness training programs 
are offered to all contractors and employees. 
The training includes raising awareness on 
heritage and artefact finds and the protocols 
for working in areas of cultural significance.
Case Study: Partnering on Cultural Heritage Management  for Carrapateena Project Development OZ Minerals and the Kokatha Aboriginal Corporation (KAC) partnered to inform the development of the Carrapateena mine. Since 2016, extensive cultural heritage survey works have been completed to define the location and construction methodology of the project infrastructure including but not limited to the Tjungu village and airstrip, bore fields, processing infrastructure, Tailings Storage Facility, communications infrastructure, electricity infrastructure and access roads. To enable this extensive development of the Carrapateena Project, teams and representatives from the Kokatha Aboriginal Corporation established a cultural heritage services business that completed over 210 days of cultural heritage surveys, equating to over 17,800 hours of field work.This early engagement and collaborative fieldwork enabled Stakeholder values to inform the design of the project and was enshrined in the Partnering Agreement, Nganampa palyanku kanyintjaku ‘Keeping the future good for all of us’. This Partnering orientation to project development created value for all stakeholders by embedding the joint values of both organisations to ensure all decisions were based on FPIC. During construction of the Carrapateena mine, Kokatha Aboriginal Corporation cultural heritage monitors were on site for over 418 days pre-pegging work areas prior to land disturbance activities and monitoring land disturbance works. This collaboration with the Kokatha Aboriginal Corporation and the Carrapateena Project team enabled the completion of construction on schedule with no cultural heritage breaches and no unauthorised land disturbance activities. During the project duration, over 26,000 hours of field work was completed with no lost time injuries.OZ MINERALS2020 ANNUAL & SUSTAINABILITY REPORTsUstainaBiLit Y rePort

Stakeholder Value Creation 
Metric: Number of human rights 
incidents
In 2020, we did not identify any Human 
Rights incidents or instances of Modern 
Slavery in our operations or supply chains.
Our Human Rights Global Performance 
Standard 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, contractors and suppliers 
through our Code of Conduct and 
Stakeholder Value Creation Polices. 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. Maintaining and improving our 
systems and processes helps to minimise  
the risk of human rights abuses in  
our operations or in our supply chain  
(Modern Slavery).

In 2020, we undertook the pre-work 
required in order to release in conjunction 
with this report our first Modern Slavery 
Statement (February 2021) as part of how  
we protect and manage human rights in 
our Assets and supply chains.
We seek to address the risk of Modern 
Slavery in our operations and supply chains 
and comply with the Modern Slavery Act 
2018 (Cth). Our people are our best defence 
in identifying and helping us to address any 
instances of modern slavery. It is therefore 
critical they understand what modern slavery 
is and how to detect it. We also want them 
to understand how our modern slavery 
risk management fits into our broader risk 
management activities. We use a variety 
of different forums and tools to raise this 
awareness. For example, our online modern 
slavery training includes defining what 
Modern Slavery is, what our responsibilities 
are and how to identify instances of modern 
slavery.
We continue to work with our supply chains 
to meet the new reporting obligations.
The OZ Minerals public and internal facing 
Anti-Bribery and Corruption material was 
updated in 2020. OZ Minerals has public-
facing speak-up material, which is supported 
by an internal ‘Speak Up’ Global Process 
Standard, to provide people with pathways 
and options to elevate concerns about 
ethical and appropriate behaviour.

ECONOMIC PERFORMANCE 
AND SOCIO-ECONOMIC 
CONTRIBUTIONS
Stakeholder Value Creation 
Metric: Social contribution – 
quantity and case studies
Our total economic contribution for  
2020 was more than $1.39 billion  
and included: 
   more than $79.2 million in wages and 
benefits in Australia and Brazil
   payments to Suppliers of over  
$1.13 billion
   $74.6 million in dividends to shareholders 
   $57.8 million in royalties and  
$48.3 million in taxes
   $2.3 million in social contributions 
including ongoing partnerships, bushfire 
relief and through our COVID-19 
Stakeholder Support Program.
Operating a sustainable and 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, 
income taxes, social investment, payment of 
dividends, and payments to our workforce 
and suppliers. 
Prominent Hill and Carrapateena 
significantly contribute to local and regional 
economies. Operationally, significant 
value is generated through employment 
both 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. The vast majority of 
the Carajás workforce are from the local 
community. More details are available in

Case Study: COVID-19 Stakeholder Support ProgramThe COVID-19 pandemic has had an immense global impact. To support our Stakeholders in building capability and resilience, and to protect and enhance our communities’ health and wellbeing, OZ Minerals established a $4 million Stakeholder Support Program. The COVID-19 Stakeholder Support Program is designed to support our Stakeholders to build resilience and protect and enhance community wellbeing throughout the COVID-19 period and to support their sustainability post COVID-19. The Program is continuing into 2021.The Program has been designed to actively respond to material local needs to identify support opportunities, so our resources and contributions are aligned with, and amplify, existing COVID-19 programs and initiatives.In Brazil support has included:  local hygiene awareness campaigns  Personal Protective Equipment (PPE) for local health care workers, employees and their families  testing kits for the local municipalities. In Australia support has included:  funds for the South Australian local industry association, Global Maintenance Upper Spencer Gulf, to increase member marketing capability and grow their businesses  Kokatha Aboriginal Corporation support for food for people unable to return to their lands due to restrictions on movement  funds for a health coordinator for the Ngaanyatjarra Council in Western Australia.OZ MINERALS2020 ANNUAL & SUSTAINABILITY REPORTsUstainaBiLit Y rePort

COMMUNITY INVESTMENT 
AND SPONSORSHIP
In 2020, we contributed to a 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. In 2020, we 
contributed $1.9 million in sponsorships and 
donations. Our social contribution program, 
Educating the Next Generation, provides 
ongoing support to the Clontarf Foundation 
which encourages Aboriginal boys to remain 
in secondary school through sport and to 
The Smith Family to provide educational 
support to girls predominantly in the areas 
near our South Australian Assets. We also 
provide ongoing support to the Royal Flying 
Doctor Service, which in turn provides 
medical assistance to our remote mine sites 
and the surrounding remote communities. 
In early 2020, we donated to the Country 
Fire Service and the Nature Foundation 
following the bushfires in South Australia. 
At the onset of the COVID-19 pandemic, 
we established a Stakeholder Support Fund 
which provided over $1.1 million in funds to 
support communities and organisations in 
the areas where we operate in Australia and 
Brazil. Direct donations are complemented 
by in-kind contributions and employee 
volunteering.
Case Study: Royal Flying Doctor ServiceOZ Minerals has continued our partnership with RFDS — OZ Minerals is committed  to promoting a culture that ensures communities close to our operations benefit from our presence.In developing sponsorships and community investment initiatives, we try to  avoid creating dependency; rather support organisations or projects to achieve  self-sustaining outcomes.Case Study: Brazil COVID-19 Response As the world comes together to combat the COVID-19 pandemic, supported by the OZ Minerals COVID-19 Stakeholder Support Program, the OZ Minerals Brazil team has been working with employees, suppliers and host communities in the donation  of COVID-19 tests, PPE, hygiene kits and medicine to local communities. 104
TAX TRANSPARENCY
LOCAL ENTERPRISE  
AND PROCUREMENT
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 2020 and provides the following 
information in accordance with the TTC: 
Tax governance 
The objectives of OZ Minerals’ tax risk 
management include 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 
are maintained at insignificant levels for 
tax exposures across our global business. 
While OZ Minerals is entitled to certain 
tax concessions in the ordinary course of 
our business, we have no appetite to seek 
concessions that are motivated by the 
avoidance of tax.

contribution summary 
A summary of OZ Minerals’ 2020 employee 
and tax related contributions to State and 
Federal tax authorities is provided in the 
performance data tables on page 115-116.
Stakeholder Value Creation 
Metric: Supplier value by 
jurisdiction – local, state, 
national, international, total
We seek to create enduring and sustainable 
value for our host communities, states 
and territories associated with our assets 
and seek to employ local people and 
engage local 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, Land 
Connected and Indigenous Peoples are 
encouraged to apply for positions and 
tender for business opportunities with  
our Assets. 
OZ Minerals directly procured the following:
   $20.7 million locally (Upper Spencer Gulf)
   $276.7 million South Australia
   $1.071 billion Australia
   $51.7 million internationally (inc. Brazil)
   $1.135 billion total.
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 contract 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 and Brazil. 
Stakeholder Value Creation Metric: Value spent  with local suppliers through supply chainsCase Study: Local content and supplier capability Since 2016, OZ Minerals has been partnering with Global Maintenance Upper Spencer Gulf (GMUSG) to co-design and facilitate local supplier capability services. During this period, GMUSG has supported contractors at Carrapateena to procure $268 million of goods and services from South Australia, of which at least $44.3 million was from and the Upper Spencer Gulf Region. In 2018, this partnership was expanded to support our Prominent Hill mine and development of the Hill to Hill (H2H) power transmission line construction.In 2020, in response to COVID-19 restrictions, GMUSG and OZ Minerals partnered as part of our COVID-19 Stakeholder Support Program to enable local business and community continuity, resilience and adaptation following the disruption of lockdowns and restrictions. The Program has helped to deliver an intensive service for small and medium enterprises across the Upper Spencer Gulf who do not have the documentation to best place them to win bids through online and competitive channels.  It has increased the confidence of businesses to promote their capabilities,  as well as compete and win work within and beyond their region. This reflects  OZ Minerals’ commitment to developing more resilient and adaptive businesses  who continue to employ and support local communities. OZ MINERALS2020 ANNUAL & SUSTAINABILITY REPORT105

HEALTH AND 
WELLBEING
OUR CONTEXT: 
The criticality of health and wellbeing 
were elevated for our people and their 
family and friends during COVID-19. 
Mental as well as physical health was a 
high priority as our people adjusted to 
changes in work rosters, working from 
home and the effects of restrictions on 
social interaction, movement and travel. 
Activities that enhanced wellbeing 
included the requirement for our people 
to develop work–life plans, enabling 
them to build their work around their 
life with flexible working arrangements 
encouraged. 
Other activities include:
   Progressing initiatives to increase 
the diversity of people within the 
organisation.
   Supporting the employment of  
local and Aboriginal people. 
   Approaches that improve gender  
pay equity and representation. 
   Targeted training programs to increase 
participation and retention of people 
of diverse backgrounds.
OUR CHOICES:
Strategic Aspirations
   We work with the best talent and capability 
no matter where it resides, driving an 
outcome-based organisation.
   We deliberately weave personal and 
professional growth into our everyday  
work, enabling people to do the best  
work of their lives. 
   We are a virtual organisation, bound by  
our Purpose and Aspirations, not by 
geography or physical infrastructure.
   We challenge all assumptions about  
how and where work needs to be done  
and what’s possible.

Stakeholder Value Creation 
Metric: Engagement Survey 
Results above industry 
benchmark
In 2020, OZ Minerals’ engagement  
survey score was 8.2, placing us in the  
top five per cent of the industry (energy 
and utilities). 
Our people’s health and wellbeing is 
important to us. People with a strong 
sense of wellbeing are more engaged at 
work and are better participants in their 
communities and families. In 2020, 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. Mental health was 
a core focus in 2020 within the COVID-19 
environment with dedicated programs at 
all of our Assets and our corporate office 
in Adelaide. 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. Our people also 
have access to corporate health plans and 
income protection.
Case Study: Inclusion and WellbeingOZ Minerals has continued our cultural journey to become a modern mining company. Integral for us to build this culture was a sustainably inclusive environment. Our focus on inclusion and diversity drives systemic, long term change focused on shifting mindsets, systems and symbols rather than only targeting diversity. This gave rise to  the development of activities aimed at deeply embedding inclusion and diversity into how we work so the inclusive environment created is unaffected by natural attrition of people, and is  an ingrained part of the Company. Key activities include:   our inclusive, bottom-up approach in evolving our HWWT behavioural framework that intentionally integrates and calls out inclusive behaviours   company-wide, immersive HWWT training focused on building an inclusive culture   measuring and tracking inclusion maturity   leveraging learnings from COVID-19 to accelerate flexible working so our jobs are more accessible   delivering annual mental and physical wellbeing programs   bi-monthly anonymous employee engagement surveys, and subsequent quarterly updates to the ELT. During COVID-19 for example, we were able to track our people’s wellbeing and mental health through our existing engagement survey and respond to a number of concerns raised. In 2020, each of the Assets has implemented programs to support mental health  and inclusion. This has included ‘Yarning Circles’ at Prominent Hill for Aboriginal employees; the Women’s working group and support networks at Carrapateena; transitioning participants in pre-employment and apprenticeship programs at Carrapateena focused on supporting young women and young Indigenous people; the completion of a mentoring pilot program; and providing education and support regarding mental health.108
BUSINESS ETHICS AND 
ETHICAL CONDUCT TRAINING
CODE OF CONDUCT
ozminerals.com/uploads/docs/201113_ 
OZ_Minerals_Code_of_Conduct.pdf
TRAINING AND DEVELOPMENT
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) Global Process Standard. 
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.
We are committed to ensuring our 
employees have access to career 
development while working at OZ Minerals. 
It is a requirement for each employee 
to have a development plan in place to 
support their career aspirations. This year, 
employees across the company undertook 
secondments to different areas of the 
business, participated in mentoring and 
coaching programs and attended formal 
training and conferences. Secondments 
between Brazil and Australia were curtailed 
due to COVID-19 restrictions, but technical 
engagement continued using virtual 
meetings. 
Our Leadership Development Programs 
focus on developing exceptional leaders 
who are inclusive, collaborative and 
innovative. Our HWWT principles and 
behaviours provide the foundation for 
how we conduct our activities. This 
year our workforce undertook a total of 
36,032 hours of training across Prominent 
Hill, Carrapateena, West Musgrave, the 
Corporate office and the Carajás Hub, an 
average of 12 hours per person. Training 
across the company spans inductions, safety, 
business ethics, role specific, technical, and 
compliance training, designed to lift the 
capability of our workforce.
Case Study: Adam Freeling Chemical Engineering Student Adam Freeling had the opportunity to present his Honours research, supported by  OZ Minerals, at the University of Adelaide mini-Ingenuity forum. Adam’s project in partnership with Hai Huy Vo Ho unlocks value by reducing electricity usage in copper extraction during periods of higher power prices. Case Study: Exceptional Leaders Program The program’s multi-dimensional learning approach involves a four-month, iterative cycle of learning, application, and reflection so our leaders learn to:  deliver value through thinking  and acting differently  support the building of an  inclusive, psychologically safe  culture at OZ Minerals  lead complex change and establish resilience in periods of uncertainty  grow new perspectives and a greater ability to work across difference  improve decision making skills and fight ambiguity with agility  improve contextual thinking and increase cognitive habits of examining behavioural root causes outside of people and within the  OZ Minerals context.OZ MINERALS2020 ANNUAL & SUSTAINABILITY REPORTsUstainaBiLit Y rePort

INCLUSION  
AND DIVERSITY
Stakeholder Value Creation 
Metric: Inclusion maturity  
above industry benchmark 
In 2020 OZ Minerals recorded an inclusion 
maturity score of 8.2. 
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 23 per 
cent of the workforce directly employed  
by OZ Minerals, with the Board and ELT 
both having more than 30 per cent female 
representation. There are approximately 155 
Aboriginal people working at Prominent 
Hill and Carrapateena (as employees and 
contractors) – representing 9 per cent of our 
Australian workforce. 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. Annual reviews are conducted 
to provide assurance that our employees’ 
remuneration remains equitable and in line 
with market trends.
Case Study: Inclusion and Diversity This year, we saw a strong uplift in our capability to measure inclusion and diversity, through the creation of dashboards and live reporting. We ran a series of workshops embedding our company culture, of which inclusion is a key pillar.We implemented leadership programs focused on equipping our leaders with the skills to be more inclusive and continued to explore how we can support under-represented groups, with pre-employment and apprenticeship programs in place focused on increasing gender and Indigenous representation.A women’s network and support group was established at our Carrapateena mine, focused on improving working conditions and creating a network of support for women at site. We also continued our partnership with Work180, focusing on how  we can better recruit and support women. Pleasingly, we also introduced new leave entitlements, effective from 1 January 2021 that support men to take more time off to step into caring roles (as an extension of secondary carers’ leave); extend primary carers’ leave to also apply in the event of a stillbirth; introduce paid superannuation while women are on unpaid maternity leave; and incorporate the option to swap public holidays and purchase additional leave.Case Study: Gabrielle Iwanow, winner of Telstra Business Women’s AwardsIn 2020, Gabrielle Iwanow, General Manager Prominent Hill, was recognised by the Telstra Business awards in the Medium and Large Business Award. Gabrielle is a member of the OZ Minerals ELT, and looks after the mining operations, processing and all associated infrastructure at site.110
Case Study: Flexible Workforce / Work life PlanWe aspire to:  be a virtual organisation, bound by our Purpose and Strategic Aspirations,  not by geography or physical infrastructure  challenge all assumptions about how and where work needs to be done  and what’s possible  work with the best talent and capability no matter where it resides,  driving an outcome-based organisation.In working towards achieving these aspirations, we introduced work–life plans to  break the traditional assumption (and even expectation) that all Fly In Fly Out (FIFO)  jobs in mining need to be solely based onsite in a remote location for however long  a single swing might be. The introduction of work–life plans demonstrates a rethink of assumptions around when, where, and how work is done. Inextricably, it also encompasses a rethink of who the work can be done by. We’re at the start of the journey with the implementation of work–life plans, with 96 per cent of our people currently having one in place. We are also navigating what a work–life plan looks like for our people who need to be onsite to complete their work. These roles are being re-conceptualised, challenging norms and assumptions around rosters, shift start and finish times, through to the development of remote operating centres. We’ve introduced additional flexibility into our FIFO roles with a 100 per cent remote work model (working from home or off-site), 100 per cent site-based model, or a hybrid model (remote and onsite combination). Including the option of working flexibly into traditionally site-based roles has made these jobs more accessible to a wider and more diverse talent pool, increasing the quality of applicants.The work–life plans are a symbol of trust and empowerment for our people. The plans must be personalised and developed in consultation with the person’s manager, and the business does not dictate that one-size-fits-all so they can be easily tailored to suit individual needs. The plans are also reviewed regularly and on an as-needs basis to make sure they still suit each person’s circumstance, in recognition that our lives  change and each person’s situation is different. In 2021, we will continue supporting flexible and remote working through the development of remote operating centres and transforming our offices into collaborative spaces that foster connection, inclusion, and innovation.OZ MINERALS2020 ANNUAL & SUSTAINABILITY REPORT111

Operational Control on 1 January 2020.
(a)  Scope 1 refers to emissions produced directly by operation, primarily resulting from combustion of various fuels and includes CO2-equivalent values for GHGs 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.
Note: The reporting period is July 2019 to June 2020 for all Assets. The energy and emissions boundary is based on operational control as defined by the National Greenhouse and Energy Reporting 
(NGER) Act 2007. The applied global warming potential (GWP) rates and emissions factors are based on the NGER Act (2007) and the National Pollutant Inventory.

Criteria Used as the Basis of Reporting 
The criteria used in relation to the Selected Sustainability Information are the GRI Standards 
published by the GRI, Recommendations of the TCFD and Company specific definitions 
outlined in the Sustainability Report. 
Basis for Conclusion
We conducted our work in accordance with Australian Standard on Assurance Engagements 
ASAE 3000 Assurance Engagements Other than Audits or Reviews of Historical Financial 
Information and ASAE 3410 Assurance Engagements on Greenhouse Gas Statements (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;
   remote discussions with Corporate Head Office (Adelaide), Prominent Hill, Carrapateena 
and Brazil Assets;
   walkthroughs of the Selected Sustainability Information to source documentation;
   agreeing the Selected Sustainability Information included in the Sustainability Report  
to relevant underlying sources on a sample basis;
   an assessment that the Selected Sustainability Information indicators reported were  
in accordance with the criteria used as the basis of reporting; and
   reviewing the OZ Minerals Annual and Sustainability Report 2020 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 Limited. 
Use of this Assurance Report
This report has been prepared for the Directors of OZ Minerals Limited 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 Limited, 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 Limited 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 2020, and to issue an assurance 
report that includes our conclusion.
Our Independence and Quality Control
We have complied with our independence and other relevant ethical requirements of 
the Code of Ethics for Professional Accountants issued by the Australian Professional 
and Ethical Standards Board and complied with the applicable requirements of Australian 
Standard on Quality Control 1 to maintain a comprehensive system of quality control.

MINERAL 
RESOURCES 
AND ORE 
RESERVES
OZ Minerals updates its Mineral Resources and 
Ore Reserves estimates at 30 June each year, or as 
necessitated by material changes to projects. 
In 2020, estimated Ore Reserves increased from approximately 175 Mt to 550 Mt primarily 
from the inclusion of Ore Reserves from the West Musgrave Province and the change of 
the assumed mining method at Carrapateena from sub-level caving to block caving. Total 
estimated Mineral Resources increased in 2020 from approximately 1,600 Mt to 1,800 Mt, 
mostly due to a changed cut-off grade for the West Musgrave Project.
The information in this section is drawn from the following releases:

SUMMARY OF SIGNIFICANT CHANGES SINCE 2019
Prominent Hill 
Prominent Hill estimated Mineral Resource tonnes increased by 8 per cent mostly due to a 
change in cut-off grade and the inclusion of marginal grade stockpiles, offset by mining and 
stockpile depletion.
Prominent Hill estimated Underground Ore Reserve tonnes decreased by 3 per cent mostly 
due to mining depletion.
Carrapateena
In 2020 a PFS was completed on an expansion of the Carrapateena Asset and the study 
identified that it was economically and technically viable to convert from a sub-level caving 
method to a block cave mining methodology, resulting in an increase of estimated Ore 
Reserves of 91 Mt to 220 Mt.
West Musgrave Project 
In December 2020 an update to the PFS resulted in an improvement to key project  
metrics relative to the PFS release on 12 February 2020, with an increase of Ore Reserve of 
15 per cent, which remained at a Probable Ore Reserve classification exclusively. A reduction 
in operating costs subsequent to an increase in processing throughput was the ultimate 
driver for this change.
Carajás Province
An Ore Reserve estimate for Antas North was declared in 2020. 
Mining at Antas North will cease in early 2021, while the Carajás Hub will continue  
to process ore from Pedra Branca. 
Others
There have been no changes to the Mineral Resource estimates of Fremantle Doctor, 
Succoth, Pedra Branca, Cipoeiro or Chega Tudo throughout 2020.

NOTES TO THE CONSOLIDATED FINANCIAL 
STATEMENTS 
INTRODUCTION 
The principal business activities of OZ Minerals Limited (OZ Minerals or the Company) and its controlled entities (collectively the 
‘Consolidated Entity’ or the ‘Group’) were the mining and processing of ore containing copper, gold and silver; undertaking exploration 
activities; and the development of mining projects.
The Company is incorporated and domiciled in Australia and limited by shares which are traded on the Australian Securities Exchange.  
OZ Minerals’ registered office is located at 2 Hamra Drive, Adelaide Airport, South Australia 5950, Australia. 
The Consolidated Financial Statements of OZ Minerals Limited and its controlled entities for the year ended 31 December 2020:
   are general purpose financial statements prepared in accordance with Australian Accounting Standards (AASBs) and the Corporations Act 
2001 and comply with International Financial Reporting Standards (IFRS)
   are presented in Australian dollars which is also the functional currency of its major operations. The controlled entities of the Company 
have the functional currency of Australian dollars and US dollars. The financial statements of the Company include consolidation of its 
subsidiaries referred to in Note 17
   have amounts rounded off to within the nearest million dollars to one decimal place unless otherwise stated, in accordance with 
Instrument 2016/191, issued by the Australian Securities and Investments Commission.
The Consolidated Financial Statements have been prepared on a going concern basis and under the historical cost convention, except for  
the following items which are measured at fair value, or otherwise, in accordance with the provisions of applicable accounting standards:
   financial instruments, including trade receivables
   derivative financial instruments
   items of inventory and property, plant and equipment which have been written down in accordance with applicable accounting standards.
Significant judgement has been applied for the commissioning of mine development projects during the year (see Note 7):
   the Carrapateena mine commissioned on 1 January 2020
   the Carrapateena processing plant and infrastructure commissioned on 1 March 2020
   the Pedra Branca mine commissioned on 1 November 2020.
Subsequent to commissioning, revenue and associated costs of production of operating each project are recognised in the Consolidated 
Statement of Comprehensive Income and depreciation of assets is commenced. 
The COVID-19 pandemic impacted OZ Minerals’ stakeholders including its customers, suppliers and employees as measures were taken by 
governments both locally and overseas to manage the pandemic. The pandemic did not materially impact the financial results of OZ Minerals 
during the year except for minor expenditure incurred to support our stakeholders and to keep operating our Assets with the restrictions 
imposed on the movement of people. The going concern assumption remains appropriate and while asset recoverability was not adversely 
impacted, future long term impacts of the pandemic on commodity prices, foreign exchange rates, the well-being of people and material 
movements remain uncertain and could have adverse impacts in future financial reporting periods. 
Subsequent to 31 December 2020, the Board of Directors approved the Block Cave Expansion, which will unlock Carrapateena’s potential to 
be a multi-generational, lowest quartile cash cost producing province, bringing long term value to our Stakeholders. The Board of Directors 
has also resolved to pay a final dividend for the 2020 financial year, as discussed in Note 4. There were no other events that occurred 
subsequent to the reporting date which have significantly affected or may significantly affect the Consolidated Entity’s operations or results 
in future years.

GROUP PERFORMANCE
1. OPERATING SEGMENTS
Segment
Principal activities
Prominent Hill
Carrapateena
Carajás
Exploration &  
development
Mining and processing underground ore containing copper, gold and silver along with residual lower grade 
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 2019. The Carrapateena mine 
generates revenue from the sale of concentrate containing copper, gold and silver to customers in Asia,  
Europe and Australia.
Mining and processing ore containing copper and gold from the Antas open pit mine and the underground 
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.
Exploration and evaluation activities associated with other projects, including exploration arrangements  
with Minotaur Exploration Ltd, Mithril Resources, Red Metal, Mineral Prospektering i Sverige, Inversiones 
Mineras La Chalina S.A.C. and corporate development activities.
During the year, OZ Minerals acquired the residual 30 per cent interest in the West Musgrave project providing  
OZ Minerals with a 100 per cent interest in the West Musgrave project. Further details are set out in Note 8.
The Company undertakes its own exploration on tenements around existing operating and development 
Assets, including at the CentroGold project in the Gurupi province in Brazil.
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), 
and treasury activities.
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 when the associated instrument matures.

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.136
Group taxation
The Consolidated Entity’s principal operations are located in Australia and Brazil. Income tax expense, current tax and deferred tax balances 
have been determined based on the tax laws and tax rates applicable in the relevant jurisdiction.
OZ Minerals Limited and its wholly owned Australian-controlled entities are part of a tax consolidated group. OZ Minerals Limited is the head 
company of the Australian tax consolidated group. No foreign operating affiliates are consolidated for tax purposes.

Unrecognised tax losses
A review of unrecognised tax losses was undertaken during the year and additional restricted tax losses of $14.3 million tax effected  
(2019: $17.8 million) were recognised on the balance sheet. Restricted tax losses are subject to an available fraction, which limits the 
amount of loss utilisation each year. During the financial year, $8.3 million tax losses (tax effected) were transferred to the Australian  
tax consolidated group upon acquisition of Cassini Resources Limited. Australian restricted tax losses of $146.9 million tax effected  
(2019: $152.9 million) remain unrecognised at 31 December 2020, inclusive of the Cassini Resources Limited transferred losses.  
Capital losses of $595.9 million tax effected (2019: $595.0 million tax effected) remain unrecognised at 31 December 2020.

Recognition and measurement of income taxes
Current tax
The tax 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 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 period 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 2021 to pay a fully-franked dividend of 17 cents per 
share. The record date for entitlement to this dividend is 12 March 2021. 
OZ Minerals offers a Dividend Reinvestment Plan (DRP) and eligible shareholders may participate in the DRP in respect of all or part of their 
shareholding. A discount of 1.5 per cent will apply to this allocation and there is no limit on the number of participating shares. Shares will 
be allocated to shareholders under the DRP for the 2020 final dividend at an amount equal to the average of the daily volume weighted 
average market price of ordinary shares of the Company traded on the ASX over the period of five trading days commencing on 11 March 
2021. The last date for receipt of election notices for the DRP is 15 March 2021. 
The financial impact of the dividend amounting to $56.4 million has not been recognised in the Consolidated Financial Statements for the 
year ended 31 December 2020 and will be recognised in subsequent consolidated financial statements.
The details in relation to dividends announced or paid since 1 January 2019 are set out below:

An assessment of the NRV of ore stockpiles resulted in a net adjustment to increase the value of inventory by $66.5 million in 2020  
(2019: $28.3 million). This increased the total ore stockpiles held at NRV to $296.4 million. The increase is mainly a reversal of previous 
net realisable value write downs due to price assumptions partially offset by an ore inventory adjustment of $14.4 million following the 
reassessment of the low grade gold ore stockpile quantities at Prominent Hill.
Recognition and measurement of inventories
Costs are assigned to individual items of inventory on the basis of weighted average costs. Costs comprise direct materials, 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.
Net Realisable Value of InventoriesInventories 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 calculation 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 positively or negatively.OZ MINERALS2020 ANNUAL & SUSTAINABILITY REPORT

Depreciation for the year of $176.8 million (2019: $91.6 million) increased primarily due to the commencement of depreciation of the 
Carrapateena operations during 2020, following commissioning.
The mineral rights balance at 31 December 2020 of $317.2 million (net of foreign currency exchange differences) is attributable to the 
Gurupi province (2019: $332.0 million). Mineral rights of $129.5 million attributable to the Carajás province have been reclassified to mine 
development assets upon development of the Pedra Branca mine. 
(a) During the year OZ Minerals paid US$50 million (A$62.2 million) upon meeting the production milestone of copper, gold or silver  
under the original acquisition agreement of Carrapateena. This amount has been included within Mine Property and Development  
in accordance with the Group’s accounting policy. The Group did not reach the milestone of production of rare earths, iron or  
any other commodity which requires a milestone payment of US$25 million.
(b) Pre commissioning adjustment relates to Carrapateena and Pedra Branca mine pre production revenue of $37.2 million and  
$5.8 million respectively. 
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.
OZ MINERALS2020 ANNUAL & SUSTAINABILITY REPORTfinanCiaL  rePort
141
The recoverable amount is the higher of an asset’s fair value, less the cost 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 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 who would use the asset in its highest and best use.

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 date 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.
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.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, Carajás 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.142
8. EXPLORATION ASSETS
On 5 October 2020, OZ Minerals acquired the residual 30 per cent interest in the West Musgrave Project thereby consolidating its 
ownership of the project to 100 per cent. The purchase was effected by acquiring Cassini Resources Limited (Cassini) under a Scheme of 
Arrangement which included a pre-acquisition spinoff and capital return by Cassini. OZ Minerals issued 6,446,511 shares on 5 October 
2020 to shareholders of Cassini, valuing the purchase at $89.6 million. The Company also incurred $9.4 million in transaction costs directly 
attributable to the purchase which were capitalised resulting in the total cost of acquisition of $99.0 million.
The Scheme of Arrangement allows for contingent payments up to an aggregated cap of $20 million, which are payable in two scenarios:
   $10 million (or pro-rata) if OZ Minerals sells 30 per cent or more of the West Musgrave project where the implied sale value for 30 per 
cent of the project exceeds $76 million and $10 million (or pro-rata) calculated at 20 per cent of the value exceeding the implied value. 
   $10 million if OZ Minerals sells 30 per cent or more of the nickel stream to a mining company which produces, sells or markets base 
metals.
The Company also inherited a deferred payment of:
   a production milestone payment of $10 million, payable 12 months after commencement of production from the West Musgrave Project.
   a 2 per cent net smelter royalty payable from future production from the tenements within the West Musgrave and Yarawindah Project. 
The Contingent Payment and Deferred Payments are not recognised as liabilities as their payment remains wholly within the control  
of the Group.

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 via an asset purchase or 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 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 these 
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.
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.OZ MINERALS2020 ANNUAL & SUSTAINABILITY REPORTfinanCiaL  rePort

The right-of-use (ROU) assets include office space, mining equipment leases contained in mining service contracts, and powerline 
infrastructure. During the year, the electricity transmission infrastructure built to transmit electricity to Carrapateena and Prominent Hill and 
enable further expansion was commissioned by ElectraNet. The power transmission agreement was deemed to be a lease and accordingly, a 
ROU asset of $521.4 million was recognised. Corresponding lease liabilities are recognised within ‘Loans and borrowings’ in the consolidated 
balance sheet (refer to Note 14).
Recognition and measurement of ROU assets
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. However, for the leases of Powerline Infrastructure the 
Consolidated Entity has elected not to separate non-lease components and account for the lease and non-lease components as a single 
lease component.
As a lessee, the Consolidated Entity recognises a ROU 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 ROU asset and a lease liability at the lease commencement date. The ROU 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. 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. 
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 $3.7 million.
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 ROU 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. 144

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.
Mine Rehabilitation, Restoration & Dismantling ObligationsThe 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.OZ MINERALS2020 ANNUAL & SUSTAINABILITY REPORT 
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.

(a)  The increase in equity associated with employee share plans is accounted for as set out in Note 13. Shares granted are valued on grant date and accounted under the share-based payment 
expense.
Ordinary shares entitle the holder to participate in dividends and the proceeds on the winding up of the Company in proportion to the 
number of shares held. On a show of hands, every holder of ordinary shares present at a meeting in person or by proxy is entitled to one 
vote, and upon a poll each holder is entitled to one vote per share.
Recognition and measurement of issued capital
Ordinary shares are classified as equity. Incremental costs directly attributable to the issue of new shares or options are shown within equity 
as a deduction.
Shares bought and held by the Employee Share Plan Trust to meet the Consolidated Entity’s obligation to provide shares to employees in 
accordance with the terms of their employment contracts and employee share plans as and when they may vest, are classified as treasury 
shares and are presented as a deduction from total equity, until the shares are cancelled or reissued.
The Company may also issue securities as consideration for asset acquisitions in lieu of cash. The fair value of assets acquired is measured 
with reference to market observable prices adjusted for any matters specific to the arrangement. The value recognised as an increase in 
issued capital reflects the fair value of assets acquired.

(applicable to 2019 and subsequent years) was set on TSR and AISC, weighted at 70 per cent and 30 per cent respectively.
The total employee benefits expense for 2020 was $121.0 million of which $10.6 million was share-based payment (2019: $81.7 million, 
share-based payment $8.0 million).
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 conditions. When issued, the shares on vesting of performance rights rank equally in all respects with previously issued, fully 
paid ordinary shares.

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 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 is 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.

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
   interest rate 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)
(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.
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. 
150
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, gold and silver which 
are priced on, or benchmarked to, open market exchanges.
Gold derivative contracts
OZ Minerals had entered into gold forward contracts to fix the price in AUD of a portion of its forecast gold sales which were designated as 
cash flow hedges under AASB 9 and were assessed to be fully effective in managing the underlying risk. Accordingly, a fair value reduction 
of $68.6 million was recognised in other comprehensive loss and $92.7 million was transferred out of Cash flow hedge reserve to profit and 
loss during 2020. At 31 December 2020, contracts for 54,207 ounces of gold were outstanding with an average strike price of $1,782 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.
Commodity price sensitivity analysis
The analysis below reflects the impact of movements in copper and 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 per cent movement in copper and 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 $6.7 million and $4.4 million after tax impact respectively in the 
income statement on the trade receivables balance of $160.3 million (2019: $83.1 million) and 10 per cent movement in gold prices also 
has a $13.3 million after tax impact on the derivative financial liability of $36.2 million (2019: $70.6 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 per cent and all 
other variables were held constant, the Consolidated Entity’s after tax profit would have changed by $9.0 million and there would have been 
no impact to the other comprehensive income (2019: $3.8 million after tax profit; $2.9 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 per cent change in the foreign currency rate.
Interest rate risk management and sensitivity analysis
The Consolidated Entity drew down a maximum of $150.0 million, at any one time, of the available credit facility during the year with  
$100.0 million outstanding at the end of the year. The Consolidated Entity is exposed to changes in the Australian bank bill interest rate,  
as the interest on the drawn amount is based on the Bank Bill Swap Bid Rate (BBSY) plus a margin. Loans and borrowings also include  
lease liabilities recognised under AASB 16 which are subject to discounting. 
At reporting date, if the Australian bank bill interest rates increased/(decreased) by 1 per cent, the Consolidated Entity’s after tax profit would  
have not changed materially (2019: Nil). The sensitivity analysis includes impact of change in interest rates on interest bearing liabilities  
such as borrowings at the reporting date and excludes lease liabilities and mine rehabilitation provisions which are non-interest bearing 
liabilities.
152
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 per cent of the estimated value of each sale either promptly after vessel 
loading or upon the vessel arriving at the discharge port.

Three major customers (2019: three customers) who individually accounted for more than 10 per cent of total revenue contributed 
approximately 78 per cent of total revenue (2019: 81 per cent). These customers also represent 95 per cent of the trade receivables balance 
as at 31 December 2020 (2019: 94 per cent). There were no instances of customer default during 2020 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.

In the first quarter of the year, in response to the COVID-19 pandemic, the Consolidated Entity increased its unsecured revolving credit  
facility by $183.0 million to $483.0 million (2019: $300.0 million), expiring 10 April 2023. The revolving credit facility is subject to 
maintaining certain financial covenant ratios. The Company was not in breach of its financial covenants as at 31 December 2020.
The Consolidated Entity entered into additional bank guarantee facilities for a total credit amount of $150.0 million. At 31 December 2020 
bank guarantees totalling $438.5 million had been issued to support the Consolidated Entity’s contingent obligations which primarily relate 
to power infrastructure agreements and mine rehabilitation obligations, both of which are recognised as a liability as set out in the respective 
notes.
15. CONTINGENCIES
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 $438.5 million as at 31 December 2020 (2019: $369.2 million) and are issued under bilateral bank facilities that are rolled 
forward every twelve months.
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.154
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 entities, 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, certain 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
A minor legal provision has been raised in relation to the investigation into the Company’s former Cambodian operations and the events of 
2009, however the final outcome of this investigation has still not been determined.
Other
OZ Minerals Limited and its controlled entities are defendants from time to time in other legal proceedings or disputes, arising from the 
conduct of their business. OZ Minerals does not consider that the outcome of any of these proceedings or disputes is likely to have a 
material effect on the Consolidated Entity’s financial position.

17. 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 any contractual arrangements with other vote 
holders, rights arising from other contractual arrangements, 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.
Subsidiaries
During the year OZ Minerals Musgrave Holdings Pty Ltd (ACN: 640 209 392) and OZ Minerals Musgrave Operations Pty Ltd (ACN: 640 213 
341) were incorporated as wholly owned subsidiaries on 8 April 2020. Cassini Resources Pty Ltd (ACN: 149 789 337) and its subsidiaries 
Crossbow Resources Pty Ltd (ACN: 161 472 788) and Wirraway Metals & Mining Pty Ltd (ACN: 142 690 346) were acquired under the 
Scheme of Arrangement to acquire the West Musgrave exploration and evaluation assets (refer Note 8). The above mentioned entities all 
have Australian dollar functional currency.

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.
20. 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. 
During the year the Group did not enter into any related party transactions (2019: None).

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 Group’s financial position as at 31 December 2020 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:

   Consolidated statement of comprehensive income, Consolidated statement of changes in 
equity, and Consolidated statement of cash flows for the year then ended;

   Directors’ Declaration. 
The Group 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

Valuation of Low Grade Gold Ore Stockpiles ($296.4m)
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 (6.2%).
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.
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.
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 attended the Group’s internal stockpile 
survey and compared the results of the 
quantity surveyors to the volume of low 
grade gold ore stockpiles recorded in the 
Group’s model at 31 December 2020.
   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 2020 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.

OTHER INFORMATION
Other Information is financial and non-financial information in OZ Minerals Limited’s annual 
reporting which is provided in addition to the Financial Report and the Auditor’s Report. The 
Directors are responsible for the Other Information.
Our opinion on the Financial Report does not cover the Other Information and, accordingly, 
we do not express an audit opinion or any form of assurance conclusion thereon, with 
the exception of the Remuneration Report, defined sustainability information within the 
Sustainability Report and our related assurance opinions.
In connection with our audit of the Financial Report, our responsibility is to read the 
Other Information. In doing so, we consider whether the Other Information is materially 
inconsistent with the Financial Report or our knowledge obtained in the audit, or otherwise 
appears to be materially misstated.
We are required to report if we conclude that there is a material misstatement of this Other 
Information, and based on the work we have performed on the Other Information that we 
obtained prior to the date of this Auditor’s Report we have nothing to report.
RESPONSIBILITIES OF THE DIRECTORS FOR THE FINANCIAL REPORT
The Directors are responsible for:
   preparing the Financial Report that gives a true and fair view in accordance with 
Australian Accounting Standards and the Corporations Act 2001;
   implementing necessary internal control to enable the preparation of a Financial Report 
that gives a true and fair view and is free from material misstatement, whether due to 
fraud or error; and
   assessing the Group and Company’s ability to continue as a going concern and whether 
the use of the going concern basis of accounting is appropriate. This includes disclosing, 
as applicable, matters related to going concern and using the going concern basis of 
accounting unless they either intend to liquidate the Group and Company or to cease 
operations, or have no realistic alternative but to do so.
AUDITOR’S RESPONSIBILITIES FOR  
THE AUDIT OF THE FINANCIAL REPORT
Our objective is:
   to obtain reasonable assurance about whether the Financial Report as a whole is free from 
material misstatement, whether due to fraud or error; and 
   to issue an Auditor’s Report that includes our opinion. 
Reasonable assurance is a high level of assurance, but is not a guarantee that an audit 
conducted in accordance with Australian Auditing Standards will always detect a material 
misstatement when it exists.
Misstatements can arise from fraud or error. They are considered material if, individually or 
in the aggregate, they could reasonably be expected to influence the economic decisions of 
users taken on the basis of the Financial Report.
A further description of our responsibilities for the audit of the Financial Report is located 
at the Auditing and Assurance Standards Board website at: auasb.gov.au/admin/file/
