Message from the Chairman and CEO
Board renewal program
This phase of the Board renewal program is
drawing to a close. In 2017, Neil Hamilton
stepped down as Chairman after seven years
on the Board. Paul Dowd also stepped down
after eight years of service. Charles Lenegan
is to retire at the Annual General Meeting
in April 2018 after eight years’ service.
We thank Neil, Paul and Charles for their
valuable support and guidance.
Rebecca McGrath, who has been a director
of OZ Minerals since 2010, was appointed
Chairman. Three new non-executive directors
– Tonianne Dwyer, Peter Tomsett and Peter
Wasow – were appointed during the year,
and together they bring a depth of technical,
operational and senior management
experience from the resources sector and
other industries.
Shareholder returns
The Board’s current policy is to target a
minimum dividend payment of 20 per cent
of net cash generation, while maintaining a
strong balance sheet for investments such as
Carrapateena, buyback or other investment
opportunities. As a result of another strong
year, the Board declared a total, fully-franked
dividend for 2017 of 20 cents per share,
made up of a half year payment of six cents
per share and an end-year payment of
14 cents. 2017 earnings per share totaled
77.4 cents.
2018 priorities
The outlook for copper is optimistic with
demand coming from traditional uses for
copper such as infrastructure and transport.
New uses for copper, stemming from a
global focus on the environment, also
contribute to the projected growth in
demand. These new uses include electric
vehicle batteries and cabling, renewable
energy generation and storage, and the
need for efficient and reliable transmission
of power; all of which require high usage
of copper by weight. These innovations
with a need for copper, combined with a
projected global mine supply shortfall due
to declining head grades and a lack of new
mines being developed in the coming years,
suggest that copper will remain a sought
after commodity.
Dear Shareholders,
2017 was a positive year for OZ Minerals,
achieving or exceeding our production
and cost guidance, advancing our growth
strategy and growing our cash balance
to $729 million. This positions us strongly
to support our growth strategy whilst
rewarding our shareholders with a 14 cents
final dividend. These achievements were
supported by our lean and agile approach
to delivery, our focus on building a culture
of innovation, and our capacity to work
together with our stakeholders to create
value for all.
Growing the company
and delivering to strategy
Prominent Hill demonstrated its ability to
deliver reliable and predictable results as
it achieved annual production and cost
guidance for the third consecutive year.
Its mine life was further extended to 2029
as a result of an 18 per cent increase in
underground ore reserves, underlining its
pedigree as a long life asset.
A financially robust Carrapateena copper–
gold project progressed to construction and
the West Musgrave copper–nickel project
advanced to pre-feasibility.
These developments and the broader
execution of our growth strategy will
see OZ Minerals become a multi-mine
company within the next five years and
allow us to leverage a more robust
foundation to grow shareholder value.
Innovation, safety and community
This year we pursued innovation to drive
results. We took inspiration from within
and outside our industry to learn lessons
in technology and culture that we could
adapt and apply.
There was marked progress in safety
performance at Prominent Hill during the
year, after we implemented a number of
safety improvement programs. Our overall
total recordable injury frequency (TRIF)
rate was 6.39 compared to 6.8 in 2016.
We continue to strengthen our approach
to safe work.
We completed a Native Title Mining
Agreement with the Kokatha Aboriginal
Corporation and the Partnership
Management Committee is meeting
quarterly to ensure progress is made on
our commitments, including employment
and business opportunities, as the
Carrapateena project progresses.
Looking ahead, we will continue to deliver
value for shareholders, enable growth and
position ourselves well to capitalise on the
encouraging macroeconomic sentiment
through:
/ strengthening our reputation through
the reliable delivery of the Prominent Hill
mine plan
/ on-budget and on-schedule construction
of Carrapateena
/ completing the West Musgrave
pre-feasibility study
/ continuing to strengthen our approach
to safe work
/ enhancing organisational culture by
leveraging agility, lean operations and
an innovative mindset
/ maintaining our future growth pipeline
by increasing the number of exploration
and study opportunities, and seeking
acquisitions that provide foot-holds
into priority mineralised belts
/ drilling of the Khamsin and Fremantle
Doctor mineralised systems and developing
a Carrapateena ‘phase two’ expansion plan
/ simplifying our governance systems
/ maintaining our focus on fostering
innovation and collaboration through
the business.
Finally, we would like to close by thanking
our employees, community and contract
partners, and other stakeholders for their
contribution in the past year. Their effort,
support and interest are vital to the success
of your company. Thank you.

Company Strategy
In 2017, we made major progress towards
our vision of becoming a copper-core,
global modern mining company that
delivers superior value with multiple
operating assets and a diverse exploration
and project pipeline. Our alignment with
our vision and strategy translated into
performance and achievement.
Lean business
Running a lean and agile business allows us to improve productivity
and channel the right resources to support growth and innovative
thinking. We support this way of working through simplified systems,
processes and technology, and we continuously seek ideas from our
people to improve the way we operate.
In 2017, Prominent Hill delivered at the top end of production
guidance and at the bottom of cost guidance, enabling us to take
advantage of improved copper prices and grow revenue to over
$1 billion.
Another example of lean business is our agile project evaluation at
Carrapateena. This enabled the mine’s design to be updated during
the feasibility study to relocate all underground development to
footwall host rocks in the south-west from the north-east. This move
allows the ore body to be reached earlier and for infrastructure to be
established completely outside of the mineralised zone.
Copper core
Our focus on a copper core means we leverage our existing
capabilities to promote copper as a key driver of earnings and
opportunistically target base metal assets.
Prominent Hill and Carrapateena are examples of projects that are
well aligned to our strategy, with both assets producing some of the
highest grade copper concentrates in the world. West Musgrave also
demonstrates how we can apply our in-house competencies, skillsets
and cumulative knowledge to other base metals.
Safe
Our overall total recordable injury frequency (TRIF) rate is 6.39. We
achieved a 41% TRIF reduction at Prominent Hill. We implemented
several improvement initiatives at Prominent Hill in 2017 including
a site Leadership Development Program to promote safety leadership
and a changed mindset of the importance of safety outcomes.
We also recorded 104 consecutive days injury free during the year.

Customer focus
Our proposed, innovative Concentrate Treatment Plant (CTP) would
enable the secondary processing of copper concentrate to remove
iron and other impurities, increasing the percentage of copper in
concentrate from between 30 and 40 per cent to between 55 and
60 per cent.
The CTP could be a potential strategic differentiator for OZ Minerals
that would allow us to produce high quality concentrate for our
customers against a backdrop of increasing impurities and decreasing
global concentrate grades in the copper concentrate market.
Port Augusta in South Australia has been identified as the preferred
location. Study work has also included geotechnical investigations,
cultural heritage and environmental works. Studies and test work
are continuing in 2018.
Multiple assets
Exploration and building a pipeline of growth and exploration
opportunities are important parts of our growth strategy. Our
approach to exploration sees us partnering with highly-regarded
explorers with potential opportunities that suit our portfolio.
We’ve been working hard on our exploration growth pipeline
and strategic projects with the aim of becoming a multi-asset
company.
We began development on Carrapateena, our copper–gold
project north of Port Augusta in South Australia.
West Musgrave also progressed from an exploration project to a
pre-feasibility study (PFS). This followed positive results from the
further scoping study that showed an investable base case for
Nebo-Babel and a potential upside through resource conversion.
The focus of the PFS is on regional potential as West Musgrave,
much like Carrapateena, is a new mineral province with attractive
near-mine and district opportunities.
How we work together
How we work together – how we deliver results – is as important to
us as what we deliver. A strong set of behavioural principles helps us
to build a culture that embraces change and allows us to operate in
an agile way and set up for the next phase of our growth journey.
In 2017, we made the decision to relocate our head office to the
Adelaide Airport business district. The move, scheduled for mid-
2018, reflects the next phase of our growth and will provide a
modern work environment that will improve collaboration.
Capital discipline
One of the ways we leverage capital discipline is to look at where
capital can be used efficiently to develop projects and operate assets.
We adopted an early contractor involvement (ECI) model with the
Carrapateena project to further accelerate construction readiness,
reduce project delivery risk, and drive cost and schedule certainty.
This model enabled us to proactively manage risk, particularly in
relation to minimising contract or contractor interfaces,
maintaining capital discipline and leveraging the specialist capability
of contractors.
We are continually looking for opportunities to control costs.

Prominent Hill
Prominent Hill is a copper–gold-silver mine
located 130 km south-east of Coober Pedy
in South Australia, with a mine life that
currently extends to 2029.
Prominent Hill consistently and reliably
delivers results. It met copper and gold
production and cost guidance for the third
consecutive year in 2017 and generated
$452 million in free cash.
Highlights for 2017 included:
/ achieving annual copper and gold guidance
despite severe weather early in the year
/ improved safety performance with a 41%
reduction in TRIF
/ entering into an 18-month power purchase
agreement to provide price certainty for
Prominent Hill’s power supply until the end
of 2018
/ breaking through the second permanent
access decline from the underground
mine into the open pit, which yielded
improvements to underground operations,
enhanced productivity and reduced costs
/ partnering with technology specialists
to evaluate advanced analytics and machine
learning to optimise plant effectiveness
/ achieving the milestone of mining one
million tonnes of ore from the open pit
since it began its life in 2009.
Prominent Hill’s transition to an
underground-only mining operation steadily
progressed through the year. The open pit
closure has been brought forward to the
first quarter of 2018 as we implemented
opportunities to accelerate open pit mining.
In 2017, decommissioned equipment from
the open pit was progressively removed
from site and open pit activities began
transitioning to the underground team.
Safety is an ongoing priority at Prominent Hill
and we implemented several improvement
strategies during the year. These
improvements have significantly reduced
Prominent Hill’s TRIF rate and we set a new
site record of 104 days recordable injury free.
The Prominent Hill mine
has achieved copper
guidance for three
consecutive years and
continues to generate
value through strong
operational discipline and
the delivery of consistent,
safe, cost effective
production.
Our focus for 2018 is on:
/ enhancing operational risk management
with a focus on leadership and safe
behaviours
/ maintaining strong operating discipline
to reliably deliver results in the bottom
half of the cost curve
/ continuing to extend mine life year
on year
/ completing the demobilisation of the
open pit and ensuring an uninterrupted
transition to underground-only production
/ completing work on waste dump
rehabilitation as part of a continuous
mine closure strategy
/ establishing increased opportunities to link
local businesses and the traditional owners
of the land where the Prominent Hill mine
is based.
Safety improvement
initiatives included:
/ focusing on safety behaviour in the
underground
/ implementing new safety, health,
environment and community
performance standards
/ embedding a Critical Risk Observation
program into ours and our contractors
work practices across site. Critical risks
and their controls were derived from an
extensive risk assessment process
/ establishing an updated Principle Hazard
Management Plan for Vehicle Operations
with higher standards for equipment,
road design and operator requirements
/ continuing programs to reduce
musculoskeletal injury; revising the
occupational hygiene management plan;
and establishing an improved targeted
monitoring program
/ improving access and response to medical
emergencies on site, with the merger and
relocation of the Medical and Emergency
Response facility.
Power was a focus this year. In mid-2017, we
entered into an 18-month power purchase
agreement, securing price certainty to the
end of 2018. Energy supply and transmission
options are currently in design and a range
of energy saving programs are underway.
In August 2017, BHP advised it intended to
end Prominent Hill’s access on 30 August
2020 to BHP’s transmission line from
Davenport to Olympic Dam. OZ Minerals
power strategy will be announced to the
market in Q1 2018 and will encompass
approaches to power transmission.
The year also saw Prominent Hill’s mine
life further extended to 2029, following an
18 per cent increase in underground ore
reserve to 39 Mt. Our aim is to continue
extending Prominent Hill’s underground
mine life year on year. An estimated 80 Mt
of underground mineral resource has not
been converted to ore reserve and this
could further extend mine options.
Underground mining, combined with
stockpile processing, will maintain the
plant at full capacity to 2023. With open
pit related costs already incurred, we
expect to realise substantial cash flow
through this period.

Carrapateena
Phase one construction of the Carrapateena
project began in 2017 following the Board’s
decision in August to approve development
of the $916 million copper–gold mine.
Carrapateena is one of Australia’s largest
new mining developments. It is an iron-
oxide, copper–gold deposit, located in South
Australia’s highly prospective Gawler Craton
region. The ore reserve tonnage estimate is
79 million tonnes with a copper equivalent
grade of 2.31 per cent.
A feasibility study update informed the
Board’s development decision. The study
confirmed an estimated 20-year mine life
and a Q4 2019 commissioning date, after
which Carrapateena’s plant will progressively
ramp up over an 18-month period to a
throughput rate of 4.25 Mtpa. The life of
mine average annual production is estimated
to be 65,000 tonnes of copper and 67,000
ounces of gold.
2017 project highlights included:
/ successfully delivering all works
scheduled on-time and on-budget
/ jointly receiving the Premier’s Award for
Social Inclusion 2017 for our partnering
agreement with the Kokatha Aboriginal
Corporation, traditional owners of the
land on which the project is built
/ successfully using an early contractor
involvement model to secure approximately
50 per cent of pre-production capital
for construction contracts in lump sum
contracts
/ partnering with the Industry Capability
Network and appointing a local community
relations contact to facilitate local access
to information on contract packages and
sustainable local procurement
/ commencing phase one construction
of a staged work program. Phase two
construction is scheduled to start in Q2
2018. Subject to mining lease approval,
phase two will see the construction of the
on-site processing plant and other major
operational infrastructure.
We identified multiple improvements
through the feasibility study and our agile
project evaluation and delivery meant
that these were implemented quickly to
improve the project’s economics and risk
management.
The mine design was updated during the
feasibility study to allow all underground
capital development to be moved to footwall
host rocks in the south-west from the north-
east. This is an example of our agile project
evaluation and delivery in action – we can
now reach the ore body earlier and establish
infrastructure out of the mineralised zone.
Our ongoing relationships and engagement
with the traditional owners, pastoralists
and local communities are based on mutual
respect, understanding and trust. These have
been instrumental in progressing the project.
By way of example, the Native Title Mining
Agreement (NTMA) was reached with the
Kokatha Aboriginal Corporation in just
12 months. The strong relationships
established between senior members of
OZ Minerals and Kokatha in 2016, during
development of a partnering agreement,
made the formal NTMA’s rapid development
possible. A Partnering Management
Committee with representatives of Kokatha
and OZ Minerals now meets quarterly to
operationalise the NTMA.
We also received valuable feedback on
Carrapateena’s Mining Lease Proposal from
engagement and consultation activities
with local communities, landowners and
businesses in the Upper Spencer Gulf.
One of Australia’s largest
undeveloped copper
deposits, Carrapateena,
will be a 4.25 Mtpa
underground sub-level
cave operation, with an
estimated mine life of
20 years.
Carrapateena is expected
to generate operating
cash flow by Q4 2019.
Carrapateena is located
in a region highly
prospective for additional
resources, with known
mineralisation at Khamsin
and Fremantle Doctor.

West Musgrave
The West Musgrave copper–nickel project is
the first project in our exploration pipeline
to advance through the stages to a pre-
feasibility study.
The Project is located in the highly
prospective Musgrave Province of Western
Australia near the South Australian and
Northern Territory borders and it is Australia’s
largest undeveloped copper–nickel deposit.
OZ Minerals decided to proceed to the next
stage of our earn-in agreement, following
the November release of the further scoping
study results from our joint venture partner,
exploration company, Cassini Resources.
Under this agreement we can earn 51 per
cent of the Project by spending $19 million
within 18 months and up to 70 per cent by
spending a total of $36 million.
The further scoping study demonstrated
an investable base case for the Nebo-Babel
deposits with upside potential through
resource conversion. We are looking to
develop the Nebo-Babel deposits into a low
cost, scalable, long life operation. It presents
as a gently-dipping orebody conducive to
large-scale open pit mining.
The further scoping study evaluated
several development scenarios ranging
from six to 12 Mtpa throughput. The study
demonstrated the Project’s economic viability
at all of the throughput scenarios with strong
annual nickel and copper production and
low operating costs. The 10 Mtpa scenario
presented the most financial potential.
At 10+ Mtpa, the Project has an estimated
annual production rate of 20,000–25,000
tonnes of nickel, 25,000–30,000 tonnes of
copper and 700–1,000 tonnes of cobalt.
The project has an eight-year mine life but
as the confidence of the resource improves,
it is likely to extend to beyond 15 years.
Its average net cash flow is expected to
be $120-$150 million(d).
Nebo and Babel contain a combined
indicated and inferred mineral resource
estimate of 283 million tonnes at 0.39
per cent copper and 0.36 per cent nickel.
The copper equivalent grade is 1–1.2 per
cent. The Succoth inferred mineral resource
estimate is 156 million tonnes at 0.6 per
cent copper(e). A significant amount of the
Nebo-Babel mineral resource occurs beneath
shallow cover of less than 50 metres.
The Musgrave area is an exciting new
mineral province with attractive near-mine
and district opportunities.
OZ Minerals will be managing the PFS
which will focus on improving metallurgical
recoveries, lower cost non-process
infrastructure, and resource conversion.
Cassini will manage a four million dollar
exploration program that will focus on
regional potential, including the One Tree
Hill prospect and Succoth copper deposit.

Exploration and Growth
OZ Minerals’ dynamic pipeline of potential
growth opportunities advanced and
expanded in 2017.

mineralisation and alteration consistent with
a magnetite-hosted IOCG system.
/ 35 metres at 0.35% Cu and 0.05 g/t Au
from 197 metres at J1 conductor, Hole
EL17D06
Two new international earn-in agreements
were signed, Oaxaca in Mexico and Alvito
in Portugal, and one new Australian
agreement was established for Punt Hill near
our Carrapateena project in South Australia.
The Yandal One exploration joint venture
with Toro Energy, and the Intercept Hill
exploration joint venture with Red Tiger
were exited when drilling programs did
not meet the required technical hurdles.
We conducted drilling and geophysics
programs during the year to progress
projects in our exploration portfolio with
some encouraging results from Eloise,
including 27 metres at 2.42% Cu and
0.71 g/t Au from 435 metres in Hole
EL17D06(f).
In a major undertaking, we made our
extensive and growing bank of exploration
and growth data more readily accessible.
We partnered with Amazon Web Services
to consolidate and simplify the way these
large and complex exploration data sets
are stored, accessed and analysed.
We anticipate spending $10–$15 million
on exploration in 2018, which excludes
expenditure on the West Musgrave project
($20–$30 million) and the Carrapateena
district ($8–$10 million).
Oaxaca with Acapulco Gold Corp
comprises three newly-identified base
metal properties in Oaxaca, South Mexico.
Acapulco Gold is a private exploration
company based in Canada with significant
experience and a discovery track record
in Mexico.
The sites being targeted have the potential
for volcanic-hosted massive sulphide (VHMS)
deposits. VHMS deposits are significant
contributors to the global production of
copper, zinc, lead and silver.
Geological mapping and geochemical
sampling were undertaken in 2017 to
identify high priority targets. Subsequent
reconnaissance mapping and sampling
resulted in the discovery of surface copper
mineralisation. Drill hole permitting for
Riqueza Marina is currently underway,
with a drill program expected to commence
in mid-2018.
Alvito with Avrupa Minerals targets iron-
oxide copper–gold (IOCG) mineralisation at
the Alvito site, located 60 km south-east of
Lisbon. Avrupa Minerals is a Canadian-listed
exploration company.
The Alvito project is characterised by a 24
km long copper-in-soil anomaly with limited
In 2017, a ground geophysics program was
completed across the entire project area,
highlighting numerous targets, including a
positive gravity anomaly that coincides with
a key geological contact. Drilling of priority
targets is set to commence in the first half
of 2018.
Intercept Hill with Red Tiger Resources
is an IOCG exploration project located 30 km
north-west of the Carrapateena project.
Targets were generated from reprocessed
geophysical data and the work indicated
that significant anomalies may have been
overlooked. Four drill holes were completed
during 2017 with no significant results.
This project was subsequently exited.
Coompana with Mithril Resources
consists of seven exploration licences in
South Australia’s far western Coompana
Province. Mithril is an experienced nickel
and copper exploration company based
in South Australia.
A significant amount of airborne and ground
geophysics has been conducted in the area
by the South Australian Department of State
Development in collaboration with PACE
Copper. A scientific drill program sponsored
by Geological Survey of South Australia in
conjunction with Geoscience Australia was
undertaken in 2017 and results are expected
in 2018.
Eloise with Minotaur Exploration
focuses on Cannington-style lead–zinc–silver
mineralisation and Eloise-style high grade
copper–gold mineralisation in the highly
prospective Eastern Succession of the
Mount Isa block in Queensland.
A drilling program in 2017 completed four
additional diamond drill holes (~3,000 m)
that tested the Iris and Electra anomalies,
with all holes intercepting low-grade
copper–gold mineralisation.
The focus of work has now moved to the
southern portion of the licences, which hosts
the eastern flank of the Levuka shear zone.
A 90 line-kilometre electromagnetic survey
completed over this area identified a large
number of interpreted bedrock conductors,
including the large Jericho anomaly.
The Jericho prospect comprises two linear,
multi-plate conductive zones 3–4 km in
length, modelled to be 50–275 m below
surface. The prospect was tested by
eight diamond drill holes and copper
was intersected in all holes. Some of the
better intersections returned include:
/ 27 metres at 2.42% Cu and 0.71 g/t Au
from 435 metres at J2 conductor, Hole
EL17D06
/ 46 metres at 0.74% Cu and 0.17 g/t Au
from 214 metres at J1 conductor, Hole
EL17D09
/ 4.4 metres @ 1.6% Cu and 0.5 g/t Au from
456 metres at J2 conductor, Hole EL17D09.
A single drill hole was completed at the
Arlington and St Louis prospects. Pyrrhotite
and minor chalcopyrite were returned in
both holes. Exploration in 2018 will continue
to focus on the southern licence area,
and will include further drill testing of the
Jericho conductor.
Mount Woods with Minotaur
Exploration targets copper resources in
the tenements surrounding OZ Minerals’
Prominent Hill mine. It is focused on
identifying and drilling IOCG and iron
sulphide–copper–gold (ISCG) targets.
This innovative agreement gave Minotaur
access to OZ Minerals’ repository of
exploration data from over 15 years so
they can use their regional expertise to
interrogate the database for new drill testing
targets. This also provides an opportunity
to accelerate the search for new copper
resources in the Prominent Hill district.
Four priority conductors were identified and
drilled in late 2017, with only minor skarn
related mineralisation intersected at the
Maverick prospect.
Punt Hill with Red Metal targets IOCG
mineralisation in the area adjacent to
Carrapateena. Red Metal is an ASX-listed,
Australian mineral explorer with exploration
experience in Australia’s most productive
mineral provinces.
Previous work on Punt Hill uncovered many
examples of IOCG mineralisation and one
of the new prospects shows a number of
geophysical similarities to the deposits at
Carrapateena. Subject to the successful
negotiation of a Native Title Mining
Agreement, drilling is expected to take
place in the second half of 2018.

Governance Framework
All corporate and further-developed asset
documents comply with the laws and
regulations of the jurisdiction in which
each asset operates.
Internal and external audits
OZ Minerals conducts regular audits to
systematically and objectively verify that
it conforms to performance management
standards and legal requirements, and
in order to recommend ways to improve
safety, health and wellbeing along with
environmental and social performance.
Further audits are undertaken commensurate
with the risk profile.
The governance
framework at OZ Minerals
has been designed to
enable lean business
processes that drive
clear accountabilities
and create room for
innovation.
We focus on what matters, and set processes
that create value, embrace the devolved
business model and provide clarity for new
assets, partners, suppliers and employees
coming into OZ Minerals.
Our values and behaviours drive transparency
and fair dealing, and propagate a culture of
performance and devolved accountability
– this allows us to deliver on our Company
strategy. OZ Minerals’ Code of Conduct
applies standards for appropriate ethical
and professional behaviour and guides
OZ Minerals’ employees, directors,
contractors and partners.
The Code of Conduct reinforces the
importance of our values in carrying out our
responsibilities to shareholders, employees,
customers, suppliers, consumers and
the broader community. It provides clear
guidelines as to our expectations in regards
to a number of specific issues, such as
conflict of interest, gifts, entertainment and
gratuities, anti-bribery, fraud and corruption,
equal opportunity, whistleblowing and
conflicts of interest.
OZ Minerals’ nine Company policies
work synergistically to provide a clear
representation of our intent while providing
a platform for multiple assets to work
together under a devolved model. Policy
documents, our Securities Trading Standard
and our Continuous Disclosure Standard
are available both internally and externally
and are used to clearly articulate what we
strive for to all stakeholders, partners and
communities.
Underpinning the policies are performance
standards that are grouped into four key
areas. These are safety, environment, health
and wellbeing, and social. They define the
minimum required performance to manage
sustainability opportunities and threats.
These standards will be used to audit asset
performance and set the standards for any
new assets to achieve. They are provided to
contractors and partners to outline what we
expect when they work at an OZ Minerals
asset. These documents are structured
so that each asset, contractor or partner
can use or develop their own business
standards and processes to meet our
standards, in keeping with our lean,
devolved business model.
OZ Minerals is revising its business process
standards so that they describe, in the
simplest possible way, processes or the
management activities that occur across
the business in a repeatable manner. They
are the activities that we undertake that
are unique to OZ Minerals, and they will be
used by OZ Minerals’ employees and assets.
They define the inputs and outputs required,
the processes people must follow and the
delegations that they can work within.

Environmental regulation
OZ Minerals and its activities in Australia and overseas are subject to environmental
regulations. OZ Minerals’ Prominent Hill operations, Carrapateena project, Australian
exploration activities and concentrate shipping activities operate under various licences and
permits under Commonwealth, state and territory laws, in addition to the licensing and
permit arrangements which apply to its overseas activities.
OZ Minerals regularly monitors its compliance with its licenses and permits in various ways,
including through its own environmental audits as well as those conducted by regulatory
authorities and other third parties. OZ Minerals uses a documented process to classify and
report any exceedance of a licence or permit condition, as well as any incident reportable
to the relevant authorities. All instances of reportable environmental non-compliance
and significant incidents are reviewed by the Executive Committee and the Sustainability
Committee of the OZ Minerals Board of Directors as a part of this process. A formal report is
also prepared to identify the factors that contributed to the incident or non-compliance and
the actions taken to prevent any reoccurrence.
During the year, OZ Minerals completed its ninth report under the National Greenhouse and
Energy Report Act 2009 (NGERS). Prior to the submission of the report, a comprehensive
independent audit was conducted on OZ Minerals’ processes that were developed to meet
the Act’s requirements to assure that the reported emissions, energy production and energy
consumption were prepared in accordance with the Act.
2 6
Insurance and indemnity
During the financial year, OZ Minerals Limited paid premiums with respect to a contract
insuring its directors, officers and related bodies corporate against certain liabilities incurred
while acting in that capacity. The insurance contract prohibits disclosure of the liability’s
nature and the amount of the insurance premium.
The Company’s constitution also allows OZ Minerals to provide an indemnity, to the extent
permitted by law, to officers of the Company or its related bodies corporate in relation to
liability incurred by an officer when acting in that capacity on behalf of the Company or a
related body corporate.
The Consolidated Entity has granted indemnities under deeds of indemnity with current and
former Executive and Non-executive Directors, former officers, the former General Counsel –
Special Projects, the former Group Treasurer and each employee who was a director or officer
of a controlled entity of the Consolidated Entity, or an associate of the Consolidated Entity, to
conform with Rule 10.2 of the OZ Minerals Limited Constitution.
Each deed of indemnity indemnifies the relevant director, officer or employee to the fullest
extent permitted by law for liabilities incurred while acting as an officer of OZ Minerals, its
related bodies corporate and any associated entity, where such an office is or was held at the
request of the Company. The Consolidated Entity has a policy that it will, as a general rule,
support and hold harmless an employee who, while acting in good faith, incurs personal
liability to others as a result of working for the Consolidated Entity.
No indemnity has been granted to an auditor of the Consolidated Entity in their capacity
as auditor of the Consolidated Entity.
Proceedings on behalf of the Consolidated Entity
At the date of this report there are no leave applications or proceedings brought 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 92 as required under section 307C of
the Corporations Act 2001 and this forms part of the Directors’ Report.
OZ Minerals Limited, with the approval of the Audit Committee, may decide to employ the
external auditor on assignments additional to their statutory audit duties where the auditor’s
expertise and experience with the Consolidated Entity are important, and where these
services do not impair the external auditor’s independence.
The Audit Committee has, following the passing of a resolution by the Committee,
provided the Board with advice in relation to KPMG providing non-audit services.
In accordance with the advice received from the Audit Committee, the Board is satisfied
that the provision of the non-audit services is compatible with the general standard of
independence for auditors imposed by the Corporations Act 2001. The directors are
satisfied that the non-audit services provided by the auditor did not compromise the
auditor independence requirements of the Corporations Act 2001 because:
/ all non-audit services were reviewed by the Audit Committee to ensure they did not impact
the integrity and objectivity of the external auditor
/ none of the services undermined the general principles relating to auditor independence as
set out in APES 110 Code of Ethics for Professional Accountants. These include reviewing or
auditing the auditor’s own work, acting in a management or a decision-making capacity for
OZ Minerals Limited or its controlled entities, acting as advocate for the Company or jointly
sharing economic risk and rewards.

/ Underlying EBITDA(a) of $539.4 million
and EBITDA margin of 53 per cent
/ Net assets of $2.52 billion, with cash

OZ Minerals net profit after tax for the year was $231.1 million, which was an increase of
$123.3 million (or 114%) compared to 2016. Strong production performance at Prominent
Hill in 2017 enabled OZ Minerals to fully capitalise on the buoyant copper price and deliver an
underlying net annual profit after tax of $231.1 million, an increase of $96.8 million (or 72%)
compared to 2016. EBITDA margins improved 18 per cent year on year despite the marginally
lower volume of copper sold. OZ Minerals’ cash balance of $729.4 million, an increase of
$73.7 million compared to 2016 after capital investment at Carrapateena, expenditure on
exploration activities, tax payments, and dividend payments to shareholders.

Net revenue
2017 revenue was $188.2 million higher when compared to 2016 as solid production
from Prominent Hill benefited from buoyant copper prices. Contained copper sold of
112,288 tonnes was comparable to 2016 while gold sales of 132,285 ounces were
21 percent higher.
In 2017 the average A$ copper price was 25 per cent higher than in 2016, while the
average A$ gold price was two per cent higher.
Treatment charges and refining costs (TCRC) were lower by $12.0 million as a result
of improved trading terms and lower refining charges.
Cost of goods sold
Cost of goods sold in 2017 was higher than the previous year by $59.8 million resulting from
an increased proportion of underground ore, higher power costs and royalties attributable to
the higher revenue base.
Mining costs were $20.6 million lower in 2017 as a result of the reduction in open pit mining
activity ($41.0 million), offset by increased higher grade underground mining of $20.4
million. As a result of the declining open pit mine strip ratio (approximately 0.5:1 in 2017
compared to 1:1 in 2016), the deferral of mining costs to the balance sheet was also lower
by $32.6 million in 2017.
Processing costs increased by $7.7 million, primarily due to higher power prices.
Royalties expenses increased by $10.7 million due to higher sales compared to the
prior period.
During the year, 10 million tonnes of ore were milled (2016: 9.8 million tonnes), including
2.5 million tonnes of underground ore (2016: 2.1 million tonnes). The cash inventory
adjustment of $68.7 million in 2017 was $16.7 million lower than 2016 as open pit
mining concluded in line with the mine plan and was partially displaced by increased
underground ore production. 6.1 million tonnes of open pit ore was stockpiled compared
to 7.7 million tonnes in 2016.

Other costs
Exploration and evaluation costs of $16.3
million were incurred during the year in
progressing the West Musgrave Project and
other exploration earn-in arrangements
and $5.0 million was incurred in relation
to corporate development, including
due diligence costs associated with other
non-organic growth opportunities. During
the year $3.0 million in government grant
funding was received relating to the
development of the Concentrate Treatment
Plant (CTP) technology.
Corporate general and administration costs
of $31.5 million comprise costs incurred
in direct support of operating activities
($11.0 million) and those related to largely
corporate activities ($20.5 million). Costs
allocated to support operating activities
cover a range of services and expenditure
provided at the corporate office to
the Prominent Hill, Carrapateena, and
Exploration and Development operating
segments. These include costs for sales
and marketing, strategic sourcing, business
services, information technology and
insurance.
The income tax expense of $98.3 million
was higher than the previous year as a
result of the higher profit and the benefit
of tax losses recognised in the previous year.
Net depreciation and amortisation expense
increased by $10.0 million compared to
2016. This was predominantly due to the
higher value ore milled.

Operating cash flows
Operating cash flows of $342.9 million for the year were $18.8 million higher than in 2016,
with the benefit of higher commodity prices partially offset by tax payments. Customer
receipts were $126.3 million higher as a result of the higher copper price realised during the
year. Income tax payments of $79.2 million were made during the year representing the tax
payment for 2016 of $65.5 million and the commencement of PAYG instalments for 2017
at the end of the year of $13.7 million.
Investing cash flows
Net investing cash flows of $197 million represent payments for property plant and
equipment and mine development at Prominent Hill, development costs at Carrapateena,
and receipts from the sale of surplus mining equipment.
The payments incurred related to:
/ $118.7 million in capitalised Carrapateena mine development costs
/ $16.7 million in CTP study costs
/ $46.9 million in underground operation mine development costs
/ $19.6 million of other sustaining capital expenditure
/ $4.9 million in receipts from equipment sales.
Financing activities
Cash outflows relating to financing activities of $67.0 million comprised $59.7 million in
dividend payments to shareholders and $7.3 million relating to the purchase of shares to
settle the Company’s share based compensation liabilities.
Since the end of the financial year, the Board of Directors have resolved to pay a final
dividend amounting to $41.8 million in respect of the 2017 financial year. This final dividend
will be fully franked for Australian tax purposes.

Balance sheet
Total equity increased by $162.0 million during the year to $2,516.3 million. This was mainly
due to the current year profit of $231.1 million, which was partially offset by $59.7 million of
dividends and a $7.2 million (net of tax) decrease in the value of gold derivative contracts.

The Company ended the year with a cash balance of $729.4 million and undrawn debt
facilities of $100 million, with an uncommitted facility for $300 million, providing the liquidity
and flexibility for the Company to execute its growth strategy.
Inventories at 31 December 2017 were $746.9 million, of which non-current ore stockpiles
increased by $124.4 million in line with the accelerated open pit mining strategy. A net
realisable value write back of $16.8 million was applied to the low grade gold ore stockpiles
(the estimated net realisable value is based on revenue expected to be derived from metal
contained in the ore stockpiles, based on the processing operational plan, after adjustment
for incremental costs). As open pit ore stockpiles are consumed following pit closure in
2018, the costs of mining open pit ore and the related capitalised depreciation (collectively
comprising open pit ore inventory) will be amortised progressively and recognised in the
income statement.
Trade receivables at the end of the year of $121.9 million were higher at 31 December 2017
due to the timing of shipments.
Property plant and equipment (PP&E) decreased during the year mainly due to depreciation
of Prominent Hill PP&E assets by $323.5 million which was partially offset by capitalised
underground development costs of $46.9 million, development capital expenditure at
Carrapateena of $145.4 million and sustaining capital expenditure of $19.6 million. The
Carrapateena Exploration assets of $284.9 million were reclassified as PP&E in 2017.

Risks
OZ Minerals’ operating results, financial results and performance are subject to a wide range
of risks and uncertainties (both opportunities and threats) that can be financial, political,
operational and environmental. The Consolidated Entity manages and mitigates these
risks, where appropriate, to minimise adverse impacts from threats and maximise beneficial
outcomes from opportunities. OZ Minerals’ flat corporate governance structure and direct
communication channels ensures timely responses to emerging risks. Our risk management
framework emphasises risk aware decision-making to achieve enhanced business outcomes.
The Board has oversight responsibility and determines the overall risk appetite for the
Consolidated Entity. OZ Minerals operates a risk management system with multiple lines of
defence. Line managers, operational staff and corporate functions establish standards for
managing risk and the Board and its committees review risk management as a part of their
oversight and inspection role. The Company identified risks and mitigating factors that have
the potential to affect future operating and financial performance (provided in the table
below). Developing mitigating controls for threats minimises the adverse impact on the
Company’s performance, but the Company’s future operations and financial performance
may be significantly impacted should any of these elements fail or be disrupted.
Risks and mitigating factors that could affect oZ Minerals’ future operating and financial performance
Context
Strategic risks
One operating asset
Operating only one producing
asset exposes the Consolidated
Entity to concentration risks.
Risk
Mitigation/actions
The Prominent Hill mine generates most of the
Company’s income and cash flow.
Prominent Hill now operates an integrated underground mine with multiple
areas. This mitigates sole dependence on the open pit.
The Company has an active program which focuses on using trigger action
response plans to maintain the ongoing stability of the open pit walls. The
OZ Minerals maintenance and engineering team have developed robust
procedures and practices to ensure they are operating the processing plant
with minimal disruption and at high throughput levels.
Concentrate is transported to Australian destinations using road and
rail and it is shipped to overseas destinations from the port of Adelaide.
Spillage risks (and environmental impact) are mitigated by using customised
containers with lids and rotainers to load concentrate onto ships.
The Company is developing a power strategy to align with its business
strategy, particularly in the Gawler Craton.
OZ Minerals has a clear pipeline of projects and gated plans which ensure a
disciplined approach to leverage the large resource base.
OZ Minerals evaluates each opportunity with due care and relies on expert
opinion, both internal and external where necessary, to ensure that any
potential transaction will be value accretive to the Company’s shareholders.
OZ Minerals’ maintains a segregated approach to the identification
and review of potential transactions and projects to ensure appropriate
governance is applied over the assessment of financial risk and returns.
Continuity of power supply
The Prominent Hill mine and
Carrapateena project are both
located in South Australia, which
experienced significant power
disruption in 2016.
Growth strategy
A key element of the Company’s
growth strategy is growth through
acquisition or development of
value accretive copper assets.
OZ Minerals competes with other power users for
competitively-priced uninterrupted power supply within
the prevailing environment of volatile electricity prices
and power outages in the state.
Prominent Hill power supply contracts will be
renegotiated in 2018. The Carrapateena power
infrastructure and supply agreements are currently
being developed.
The existence of a large resource at the Prominent Hill
operation, Carrapateena, Khamsin, Fremantle Doctor,
West Musgrave (JV), other exploration joint ventures
and prospectivity of the Gawler Craton.
In a climate of prospective commodity prices and
expected long-term shortages in copper supplies,
OZ Minerals competes with other entities to
acquire and develop projects that generate superior
shareholder value.
3 4
Context
Risk
Mitigation/actions
Operational risks
Project execution
Successful execution of OZ
Minerals’ growth strategy depends
on its ability to deliver projects on
time and within budget and scope.
Mine development projects are inherently exposed
to risks of scope definition, cost estimation accuracy
and other external factors which present threats
and opportunities to a project’s cost, efficiency
and profitability. These are not all within the
Company’s control.
OZ Minerals ensures its projects go through a process of internal and
external independent review to verify the engineering, technical and
financial scope definitions and other assumptions.
The Company manages project costs by sound procurement practices
and governance.
Contract management
Many aspects of the Prominent Hill
operations, Carrapateena project
and the Company’s exploration
and development activities are
conducted by contractors.
The production and capital costs incurred by OZ
Minerals are subject to a variety of factors, including
and not limited to:
/ fluctuations in input costs determined by global
markets (e.g. electricity, fuel and other key
consumables)
OZ Minerals engages with reputable contractors who have the technical
ability, proven track record and financial capability to execute its projects.
Competitive procurement processes and embedded performance
structures in contracts ensure that the Consolidated Entity mitigates
risks of non-performance by contractors, while deriving the highest value
for shareholders.
Geotechnical failure
The open pit and underground
mining operations remain subject
to geotechnical uncertainty and
adverse weather conditions.
These could manifest as pit wall
failures or rock falls, mine collapse,
cave-ins or other failures to
mine infrastructure and reduced
productivity.
Estimates of reserves
and resources
Reserve and resource assessments
involve areas of estimation and
judgement.
Customer management
OZ Minerals markets high
grade copper concentrate to
overseas and local customers.
Any disruption to the logistics
chain from production through to
delivery to the customer can result
in significant financial impact.
Market risks
Commodity prices and
exchange rates
/ changes in economic conditions that impact on
the margins required by contracting partners
/ changes in mining assumptions, such as ore
grades and pit designs.
The operating results of OZ Minerals depend
on the performance of contractors.
The open pit depth will increase until mining ceases
in 2018 and the concurrent mining of multiple
underground areas will lead to increased underground
mining activities.
OZ Minerals operates programs that monitor and respond to changes
in geotechnical structures in the open pit, underground, and tailings
storage facility to ensure the safety of personnel working in the affected
areas. Where possible, activities are undertaken to reduce the risk of
geotechnical failure.
The preparation of these estimates involves application
of significant judgment and no assurance of mineral
recovery levels or the commercial viability of deposits
can be provided. The Company reviews and publishes
its reserves and resources annually.
A concentrate’s marketability depends on global mine
supply, smelter demand, concentrate grades and
impurities in the product. Prominent Hill concentrate
has a high copper grade, containing gold and silver as
well as fluorine and uranium impurities.
Regulators in various jurisdictions may change limits
or their approach to impurity assessment guidelines
in concentrate. This can impede the importation of the
concentrate into those jurisdictions. These changes
may result in additional requirements related to the
ore, tailings or concentrates, or result in challenges
with selling, transporting or importing Prominent Hill
concentrates in various jurisdictions.
OZ Minerals does not control copper, gold, silver or
other base metal prices in the global commodities
market or the Australian/US dollar exchange rate.
The reserve and resource estimates and mine plans have been carefully
prepared by the Company in compliance with the Joint Ore Reserves
Committee (JORC) guidelines and in some instances are verified by
independent mining experts or experienced mining operators.
The estimation of the Company’s reserves and resources involves analysis
of drilling results, associated geological and geotechnical interpretations,
operating cost and business assumptions, and a reliance on commodity
price and exchange rate assumptions.
The Company’s production plan is based on the published reserves
and resources.
OZ Minerals has developed customised solutions in partnership with
customers. These match smelter demand and production from the
Prominent Hill mine to concentrate grade and timing, along with a range
of controls to manage the fluorine and uranium impurities.
OZ Minerals has multiple marketing options including, but not limited to,
ore blending, concentrates blending and additional flotation treatment in
the processing plant.
OZ Minerals maintains a diverse customer portfolio to mitigate against the
risk of regulatory changes to importation requirements.
OZ Minerals manages its exposure to copper price on sales by entering into
derivative contracts that settle at the same time as the contractual quotation
period for the sale.
OZ Minerals has entered into gold derivative contracts to fix gold price on
60 per cent of the gold expected to be sold from Q3 2018 to 2021.
OZ Minerals’ functional currency is the Australian dollar and US dollars are
only held to meet US dollar commitments.
OZ Minerals does not take active steps to hedge currency risk.
OZ Minerals operates mines with a low cost of production relative to global
copper producers. This ensures resilience to low commodity prices and an
ability to maximise margins during high commodity prices.

Risk
Mitigation/actions
Safety, health, environment, and community (SHEC )
Operational safety failures
resulting in injury or fatality
OZ Minerals undertakes operations in areas which
may pose a safety risk including, but not limited to,
handling explosives, underground operations subject
to rock fall, confined spaces, areas where heavy and
light vehicles interact, manual handling and operating
at height.
A fly-in fly-out operation also introduces risk that is
inherent in air travel, as contractors and employees are
regularly required to commute by aircraft.
OZ Minerals is committed to the safety of its people and all work processes
have a high safety focus.
OZ Minerals operates in partnership with its contractors and is actively
building a shared safety culture between employees and the contractors
who work at our sites.
Active engagement at all levels of operations and with senior leadership
teams, combined with activities focused on identifying and eliminating
drivers of safety incidents, has delivered significant successes and resulted
in a sustained reduction in the severity of injuries.
Mine rehabilitation
The Company operates under
a range of environmental
regulations and guidelines.
Environmental regulations and occupational health
and safety guidelines for certain products and by-
products produced or to be produced are generally
becoming more onerous.
Maintenance of community
relations and good title
The Company works closely with local communities,
particularly the Indigenous communities in South
Australia.
Agreements with the Commonwealth of Australia
govern the terms of access to areas located within
the ‘green zone’ of the Woomera Prohibited Area.
Climate change
Severe climate change can cause disruption to mine
production, logistics and water supply as a result of
extreme weather events.
As regulatory agencies respond to climate change
over the medium term, costs of inputs may rise and
restrictions may be placed on how certain resources
are provided, transported and used, which may impact
our licence to operate.
Climate change combined with regulatory changes
also has the potential to be a catalyst for growth
in industries that require copper and could result in
upward pressure on copper prices.
The Company is required to close its operations and rehabilitate the land
affected by the operation at the conclusion of mining and processing
activities.
Estimates of these costs are reflected in accordance with AASB 137
Provisions, Contingent Liabilities and Contingent Assets as provisions in the
financial statements. Management seeks external assistance and review,
where appropriate, to estimate these costs.
However, actual closure costs may be higher or lower than estimated as
these are costs to be incurred following the closure of mining operations
over a long time period.
Access and compensation agreements are in place with communities
affected by mining activities. These are reviewed and updated from time
to time.
The Company actively engaged with the traditional owners of Carrapateena
and this culminated in a partnering agreement with the Kokatha Aboriginal
Corporation.
The Company has controls in place to ensure compliance with the Deed and
relies on good relations with the Australian Defence Department regarding
defence operations in the Woomera region and any potential impact these
may have on our mining operations.
The Company also relies on the maintenance of good title over the
authorisations, permits and licences which allow it to operate. Loss of good
title or access due to challenges instituted by issuers of authorisations,
permits or licences, such as government authorities or land owners, may
result in operational disruptions.
The Company’s governance structure and risk management process
specifically focus on climate change risks to identify key risks and develop
response plans.
OZ Minerals is committed to reducing the energy intensity of our operations,
developing innovative practices in relation to chemical processing and being
more efficient in our transportation and processing activities.
The Company’s power strategy will consider renewable energy, power
security and reliability for its operations.
Business strategies, prospects and likely developments
This report sets out our business strategies and prospects for future financial years; likely
developments in OZ Minerals’ operations; and the expected results of our operations in
future financial years. We provide this information to help shareholders make an informed
assessment about the business strategies and prospects for the Consolidated Entity’s future
financial years. We have not included details that could give rise to a likely material detriment
to OZ Minerals, such as information that is commercially sensitive, confidential or could give
a third party a commercial advantage.

Letter from the Chairman of the Human
Resources and Remuneration Committee
Dear Shareholders,
On behalf of the Board of Directors, I am
pleased to provide you with the 2017
Remuneration Report for OZ Minerals.
2017 was a successful year for the Company.
We achieved or bettered our production
and cost guidance, extended the mine
life at Prominent Hill and commenced the
development of Carrapateena. We also
advanced our growth strategy whilst at
the same time ensured that the company’s
balance sheet remained strong. The success
of the Company during the year was a
direct result of the talent, hard work and
dedication of the Company’s employees
and stakeholders. More detail on the
Company’s performance is contained in
the Directors Report.
Remuneration outcomes in 2017
As in previous years, we have continued to
seek to ensure that remuneration outcomes
reflect the performance of the Company
and are aligned to shareholder’s experience.
In addition we sought to ensure that
executive remuneration remained market
competitive, easy to understand and could
be clearly communicated to executives and
shareholders.
Key outcomes for 2017 include:
/ Executive salaries were held at 2016 levels
during 2017
/ The strong performance of the Company
against the KPIs set by the Board for the
2017 year supported short term incentive
awards to KMPs on average 84.5% of
their maximum annual short term incentive
opportunity. Details of the KPI outcomes
can be found in section 3.2 of the
Remuneration Report
/ Reflecting the strong performance of the
Company and his leadership during 2017,
the Board determined to award 83.5% of
the maximum annual short term incentive
opportunity to the Managing Director and
Chief Executive Officer, Andrew Cole
/ The lapsing of 382,251 performance rights
following the resignations of KMPs Luke
Anderson and Robert Fulker.
Developments for remuneration
for 2018 and beyond
As activity picks up in the mining sector
and the Company enters the next phase of
its growth journey, we recognise the need
to continue to ensure reward mechanisms
are appropriately aligned. The Board also
considers it vital that Key Management
Personnel and other critical senior
management in the business are retained
during the construction and commissioning
of Carrapateena.
Accordingly the Board approved:
/ a remuneration review for the Company
for 2018. The last company-wide review
was in 2012
/ fixed remuneration increase for Managing
Director and CEO, Andrew Cole to
$800,000 per annum. This recognises
the increased scale and complexity of
the Company and its operations, and
positions his remuneration competitively
with comparable companies. His short term
incentive opportunity was also increased
from 100% to 120% for 2018. His fixed
remuneration has not been increased since
joining the Company in 2014
/ fixed remuneration increase for Head of
People and Performance, Mark Rankmore,
to $470,000 per annum to reflect increases
in the scope of his role
/ no other increases to KMP fixed
remuneration
/ one-off issue of performance rights in 2018
to ongoing KMP (other than Andrew Cole)
under an Alignment Plan. The number of
rights issued will represent 20% of the
KMP’s fixed remuneration with vesting
subject only to continuing employment on
the second anniversary of the award.
During 2017 the Company also commenced
a review of its executive remuneration
incentive structure to ensure that it continues
to align the interests of executives with those
of shareholders. This review has highlighted
some opportunities for improved alignment
which will be further developed during 2018
with a view to implementation in 2019. We
intend to consult with shareholders on these
proposals prior to implementation.
Meanwhile, following a review of the
existing Long Term Incentive plan Total
Shareholder Return comparator group
the Board has determined to amend the
comparator group of companies to give
better alignment to the Company.
Seven new comparator companies will
be added to the peer group consisting
of Independence Group, Western Areas,
Avanco Resources, First Quantum Minerals,
Antofagasta, Freeport McMoRan and
Dundee Precious Metals. Two companies
will be removed from the peer group, being
MMG Limited and Katanga Mining. These
changes will apply to the 2018 award.
The Board considers this group better reflects
the growth in the scale and complexity of
the operations of the Company. The Board
also recognises that a larger comparator
group is more reflective of shareholder
opportunity whilst also reducing the volatility
of the outcome for executives.
Finally, the Board decided not to increase the
fees paid to Non-executive Directors in 2017.
During 2018 it is intended to undertake
a review of the roles and responsibilities
of the Board and its committees and their
respective fees. Board and committee fees
have not been increased since 2012.
The Board is determined to continue our
focus on the longer-term business strategy
and deliver consistent, well-aligned and
transparent remuneration outcomes.
Thank you for your ongoing support
of OZ Minerals.
Yours sincerely,
Tonianne Dwyer
Chairman Human Resources and

2.0 Remuneration policy
table 2 – Remuneration principles
2.1 Overview of remuneration
policy and practices
The remuneration principles outlined in
Table 2 demonstrate the links between
remuneration and business strategies
and their impact on OZ Minerals actual
remuneration arrangements. The overriding
business objective is to achieve superior
returns compared to the Company’s peers
in the resources sector.
Business needs and
market alignment
OZ Minerals remuneration policy is focused on achieving our corporate objectives.
Remuneration is set having regard to market practices and aligned with achieving
shareholder returns.
Simplicity and equity
OZ Minerals remuneration philosophy, policy, principles and structures are simple to
understand, communicate and implement, and are equitable across the Company
and its diverse workforce.
Performance and
reward linkages
Market positioning
and remuneration mix
Well-designed remuneration policy supports and drives Company and team
performance and encourages the demonstration of desired behaviours. Performance
measures and targets are few in number, outcome-focused and customised at an
individual level to maximise performance, accountability and reward linkages.
Fixed remuneration is set at a competitive level and positioned to take in to account
the challenges of attracting and retaining high performers in business critical roles,
particularly in the mining industry. The ‘at-risk’ components of remuneration depend
on challenging goals and are focused on incentivising executive KMP to achieve
business critical objectives and shareholder returns.
Talent management
Remuneration policy is tightly linked with our performance and talent management
frameworks to reward and recognise employees who achieve their role
accountabilities and to engage future leaders.
Governance,
transparency and
communication with
shareholders
OZ Minerals is committed to developing and maintaining remuneration policies and
practices that maximise value. We will openly communicate these to shareholders
and other relevant stakeholders, and will always be within legal, regulatory and
industrial requirements. The Board has absolute discretion to develop, implement and
review key aspects of remuneration.

2.2 Remuneration consultants
The Board of Directors and Human Resources and Remuneration Committee seek and
consider advice from independent remuneration consultants to ensure that they have all
the relevant information at their disposal to determine executive KMP remuneration. The
engagement of remuneration consultants 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.
PROTOCOL S
Under the protocols adopted by the Board and Human Resources and Remuneration
Committee:
/ remuneration consultants are engaged by and report directly to the Board or the Human
Resources and 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 Human Resources and
Remuneration Committee must be obtained in certain circumstances where the consultant
continues to be engaged to provide remuneration recommendations.
The Board and the Human Resources and 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 Human Resources and Remuneration
Committee and consultants.
During 2017, PwC were engaged to review the Company’s executive remuneration
framework. Their observations will form the basis of further work to be undertaken during
2018 to ensure that remuneration arrangements continue to align with shareholder interests
in pursuit of the Company’s strategy. The work completed did not constitute a remuneration
recommendation in accordance with the Corporations Act 2001. The fee for work conducted
was $108,834 (including GST).
4 2
2.3 Review of executive KMP remuneration
Executive KMP remuneration levels are reviewed annually by the Board with help from the
Human Resources and Remuneration Committee and external remuneration consultants as
required. The review makes sure that executive KMP remuneration remains consistent with
the Company’s remuneration policies and guiding principles, and considers:
/ the Company’s remuneration policy and practices
/ relevant market benchmarks using salary survey data from the Australian industrial
and resources sectors
/ the skills and experience required of each role in order to grade positions accurately
and attract high calibre people
/ individual performance against role expectation, set objectives, leadership behaviours
and development plans
/ Company strategy, business plans and budgets.
2.4 Executive KMP remuneration components
table 3 – Remuneration mix
Total fixed remuneration (TFR)
At-risk remuneration
Short term incentive (STI)
Long term incentive (LTI)
The regular base reward that reflects the job size, role,
responsibilities and professional competence of each
executive, according to their knowledge, experience
and accountabilities and considering external market
relativities.
A variable, performance based, annual cash incentive
plan designed to reward high performance against
challenging, clearly defined and measurable objectives.
These are based on a mixture of targets and are set to
incentivise superior performance with specific targets or
metrics in each category.
The equity component of the at-risk reward opportunity
which is linked to the Company’s medium to long
term TSR and share price performance. A three-year
performance period applies.
The mix of fixed and at-risk remuneration varies depending on the role and grading of
executives as well as the performance of the Company and individual executives. More senior
positions have a greater proportion of at-risk remuneration. If maximum at-risk remuneration
is earned, the ratio percentage of fixed to at-risk remuneration would be as follows.

What is included in total fixed remuneration?
When and how is fixed remuneration reviewed?
Short term incentive (STI)
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 by the Human Resources
and Remuneration Committee. The Company seeks to position the fixed remuneration between the 50th and 75th
percentile (or higher) of remuneration for business critical roles in comparable companies within the mining market and
where appropriate, the broader general industry market.
Why does the Board think an STI plan is appropriate? Variable performance based remuneration strengthens the link between pay and performance. The purpose of these
What are the performance conditions?
programmes is to make a large proportion of the total market reward package subject to meeting various targets
linked to OZ Minerals’ business objectives. The use of variable performance based remuneration avoids much higher
levels of fixed remuneration and is designed to focus and motivate employees to achieve outcomes beyond the
standard expected in the normal course of ongoing employment. A reward structure that provides variable performance
based remuneration is also necessary as a competitive remuneration package in the Australian and global marketplace
for executives.
The performance conditions that determined STI outcomes in 2017 were: (a) Company key performance indicators (KPIs)
and (b) individual KPIs.
The Company KPI hurdle in 2017, accounts for 90% of the STI award for the Managing Director and CEO and
50% of the STI award for other KMP and the balance was attributable to individual KPIs.
(a) Company KPIs
Company KPIs are set and weighted at the beginning of each year. They are designed to drive successful and sustainable
financial and business outcomes, with reference to the Board approved corporate objectives, plans and budget for
the year. The key areas of focus in 2017 included improving the Company’s operational and financial performance,
sustainability performance and progressing strategic growth objectives.

b) Individual KPIs
Individual KPIs vary for each executive KMP based on their accountabilities.
The Board assesses and sets the KPIs for the Managing Director and Chief Executive Officer award, and the Managing
Director and Chief Executive Officer assesses and sets the KPIs for each of the other executive KMP in consultation with
the Board.
Is there an overriding financial performance
condition or other condition?
Yes. The availability of the STI Pool is at the discretion of the Board, which takes into account the interests of the
Company and shareholders. The Board can choose not to pay or reduce the amount of the STI otherwise payable.
How is the STI structured to reward
exceptional performance?
The STI plan is designed to reward executive KMP at three pre-determined performance levels – threshold,
target and maximum.
Threshold performance represents the minimum level of performance required for an STI award to vest.
Target performance
represents the achievement of planned or budgeted performance,
set at a challenging level.
Maximum performance represents outstanding performance, set at a stretch level.

The Managing Director and CEO assesses the business performance of executive KMP throughout the year for progress
and improvement, to arrive at a summary assessment at year end for discussion with the Human Resources and
Remuneration Committee and the Board. The Board also reviews the performance assessment of all executives who
report directly to the Managing Director and CEO, with a view to understanding, endorsing and/or discussing individual
circumstances, performance, leadership behaviours and future development. The Human Resources and 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 function of the Company, whilst the Board and Human
Resources and Remuneration Committee have overall responsibility for determining whether Executive KMP have
met the performance targets and objectives set for that year.
If an executive leaves OZ Minerals then the Good Leaver Policy may apply (subject to the executive’s contract) and,
if the requirements are met, the STI may be granted on a pro rata basis in relation to the period of service completed.
This is at the Board’s discretion and conditional upon the individual performance of the relevant executive.
The Company believes that a LTI plan can:
/ focus and motivate employees to achieve outcomes beyond the standard expected in the normal course of ongoing
employment
/ ensure that business decisions and strategic planning take into account the Company’s long term performance
/ be consistent with contemporary remuneration governance standards and guidelines
/ be consistent and competitive with current practices of comparable companies
/ create an immediate ownership mindset among the executive participants, linking a substantial portion of their
potential total reward to OZ Minerals’ ongoing share price and shareholder returns.
How is STI assessed?
What happens to STI awards when
an executive ceases employment?
Long term incentive (LTI)
Why does the Board consider
a LTI Plan to be appropriate?
How is the award delivered?
The LTI is granted using performance rights under the OZ Minerals LTI plan (detailed below).
Was a grant made in 2017?
A grant was made on 27 January 2017 to all continuing participants in the LTI plan. The number of performance
rights granted to each executive was calculated as their LTI dollar opportunity divided by the adjusted five-day volume
weighted average price of OZ Minerals as at the start of the performance period. The performance period for the 2017
LTI grant is 1 January 2017 to 31 December 2019.

grant for executive KMP?

What are the performance conditions?
The two performance conditions, referred to as the vesting conditions are: (a) the executive KMP meeting the service
condition; and (b) OZ Minerals meeting the LTI performance conditions.
Service condition
The service condition is met if employment with OZ Minerals is continuous for three years commencing on or around
the grant date (performance period).
Performance conditions
The LTI plan performance conditions for 2017 were as follows:
1. Total shareholder return (TSR)
Relative TSR is the primary LTI performance hurdle measured against a comparator group. The Board considers TSR
to be an appropriate performance hurdle because it ensures that a proportion of each participant’s remuneration is
linked to shareholder value and that participants only receive a benefit where there is a corresponding direct benefit
to shareholders.
TSR reflects benefits received by shareholders through share price growth and dividend yield and it is the most widely
used long term incentive hurdle in Australia. The Company employs an independent organisation to calculate the TSR
ranking to ensure an objective assessment of the relative TSR comparison. Performance rights in respect to this hurdle
will vest in accordance with the following table.

The TSR performance hurdle accounts for 70% of the LTI award.
2. Absolute share price growth
Absolute share price growth is the second LTI performance hurdle. This hurdle will be satisfied if the OZ Minerals share
price has increased by at least 20% over the performance period. Performance rights in respect to this hurdle will vest in
accordance with the following table.
table 4.5 – Performance rights vested according to absolute share price growth
OZ Minerals share price growth

Proportion of performance – related
performance rights that vest
Less than 20%
20% or greater
0%
100%
The absolute share price growth hurdle accounts for 30% of the LTI award.
Why were the performance conditions chosen?
It is standard market practice to link individual executive performance (including mandatory service periods) and
Company performance to the vesting of performance rights. The conditions link executives’ retention and performance
directly to rewards, but only where shareholder returns are realised. The focus on employee-held equity is also part of a
deliberate policy to strengthen engagement and direct personal interest to achieve shareholders returns.

What is the comparator group?
The comparator companies selected for 2017 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.

What happens to performance rights granted under
the LTI plan when an executive ceases employment?
What happens in the event of a change of control?
Is there any ability for the Company to ‘clawback’
LTI awards?
Do shares granted upon vesting of performance
rights granted under the LTI plan dilute existing
shareholders’ equity?
Does the Company have a policy in relation to
margin loans and hedging at risk remuneration?
If the executive’s employment is terminated for cause, or if they resign, all unvested performance rights will lapse
unless the Board determines otherwise. In all other circumstances, unless the Board determines otherwise, a pro rata
portion of the executive’s performance rights, calculated by reference to the portion of the performance period that has
elapsed, will remain on foot, subject to the performance condition as set by the Board. If and when these performance
rights vest, shares will be allocated (or a cash equivalent amount will be paid) in accordance with the OZ Minerals’
Equity Incentive Plan Rules and any other conditions of grant.
In the event of a takeover or change of control at OZ Minerals, the Board has the discretion to determine that vesting
of all or some of the performance rights should be accelerated. If a change of control occurs before the Board has
exercised its discretion, a pro rata portion of the performance rights will vest, calculated on the portion of the relevant
performance period that has elapsed up to the change of control. The Board retains discretion to determine if the
remaining performance rights will vest or lapse.
In the event of fraud, dishonesty, gross misconduct or material misstatement of the financial statements, the Board may
make a determination that could include the lapsing of unvested performance rights the forfeiture of shares allocated
on vesting of performance rights and/or repayment of any cash payment or dividends to ensure that no unfair benefit
was obtained.
Generally, there is no dilution of shareholders’ pre-existing equity as shares allocated to LTI plan participants upon
vesting of performance rights are usually satisfied by purchases by the plan trustee on market.
Under the Company’s Securities Trading Policy, all executives, directors and officers are prohibited from entering into
financing arrangements where the monies owed to the lender are secured against a mortgage over OZ Minerals’
shares. The Company’s Securities Trading Policy also prohibits executives and employees from entering into any hedging
arrangement over unvested securities issued pursuant to any share scheme, performance rights plan or option plan.

3.3 LTI performance and outcomes
Performance rights granted under the OZ Minerals LTI Plan are granted for no consideration. Performance rights carry no dividend or voting
rights. One ordinary share in the Company will be allocated on vesting of a performance right. The vesting condition for each grant is the
relative TSR performance and absolute share price growth of the Company over the relevant performance period. In general, the executive
must also remain employed with OZ Minerals for a continuous period of three years from the grant date. Details of the prior awards for
relevant executive KMP are set out in the Remuneration Report for the year in which they were granted.
Details of the performance rights held by executive KMP that lapsed during the year are set out in Table 15. Additional details are set out in

(a) The maximum value of the grants has been estimated based on a 52-week high closing share price in the calendar year of the grant. For the 2017 grant, this was $9.99 per instrument. The minimum
total value of each grant, if the applicable performance conditions are not met, is nil.
(b) The fair values were calculated as at the grant dates. In accordance with the requirements of applicable accounting standards, remuneration includes a proportion of the notional value of performance
rights as compensation granted or outstanding during the year. The notional value of performance rights granted as compensation is determined as at the grant date and progressively allocated over
the vesting period. The amount included as remuneration is not related to or indicative of the benefit (if any) that individual executives may in fact receive. The values were calculated by an external
third party based on a Monte-Carlo simulation model.

(a) Annual leave has been separately categorised and is measured on an accrual basis and reflects the movement in the accrual over the twelve-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 based on quarterly contribution limits under Super Guarantee Charge regulations (in 2016 contributions were based on annual contribution
limits). 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 twelve-month period which will only be paid if executive KMP meets the required service conditions.
(d) Termination benefits include the value of benefits such as payment for notice period and leave balances paid upon termination.
(e) The fair values were calculated as at the grant dates. In accordance with the requirements of applicable accounting standards, remuneration includes a proportion of the notional value of equity rights
compensation granted or outstanding during the year. The notional value of equity rights granted as compensation which do not vest during the reporting period is determined as at the grant date and
progressively allocated over the vesting period. The amount included as remuneration is not related to or indicative of the benefit (if any) that individual executives may in fact receive. The values were
calculated by an external third party based on a Monte Carlo simulation model.
(f) Appointed 4 December 2017.
(g) Resigned 29 September 2017. Benefits include the termination benefits.

6.1 Non-executive director
remuneration policy
Non-executive director (NED) remuneration
is reviewed annually by the Board. NEDs
receive a fixed fee remuneration consisting
of a base fee rate and additional fees for
committee roles.
Consistent with best practice, NEDs do not receive any form of equity incentive entitlement,
bonuses, options, other incentive payments or retirement benefits. As approved at the
OZ Minerals General Meeting on 18 July 2008, the maximum fees payable per annum
is $2,700,000 in total. The Board decided not to increase the fees paid to non-executive
directors in 2017 based on the Human Resources and Remuneration Committee’s
recommendation.
The Board intends to review the Board and Committee fees as part of its review of the Board
and committee structure during 2018.

Sustainability
Report

Format and scope
This is our second year of publishing a
combined annual and sustainability report
to support our approach to creating
value in a financially, environmentally
and socially responsible manner for our
shareholders and other stakeholders.
You’ll find examples of sustainability in
practice embedded throughout the report
to reflect how sustainability is integrated
into our operations.
We disclose sustainability data in accordance
with selected Global Reporting Initiative (GRI)
Standards (version G4), a comprehensive set
of guidelines that cover all dimensions of
sustainability. We also reference supporting
documents which form part of our
sustainability disclosure. These documents
are publicly available on our website to
make specific information more accessible.
We use a materiality assessment to
determine key topics that matter most to
our stakeholders and us. The sustainability
section of this report focuses on these
topics. The material topics have not
changed substantially from last year.
We prioritise sustainability topics based on
the significance of economic and social
impact and the relevance to our stakeholders
and the decisions they make. Material topics
identified as having a high priority for both
the business and stakeholders are discussed
in this report. Other topics are mentioned in
the report and on the Company website.
We identified material topics in compliance
with the GRI guidance on materiality and
completeness, and with reference to a range
of internal and external considerations and
priorities. The process included extensive
document review, surveys, and dialogue
with internal and external stakeholders.
We report on all aspects of OZ Minerals’
operations and our operating subsidiaries,
including joint ventures where we have
operational control, for the 2017 calendar
year (unless otherwise stated).
OZ Minerals’ sustainability
performance is recognised
OZ Minerals was selected as member of the
Dow Jones Sustainability Indices (DJSI) in 2017.
This recognises our corporate sustainability
leadership within our industry. Since
RobecoSAM launched the globally renowned
DJSI series in 1999, it has driven innovation
in environmental, social and corporate
governance (ESG) investment.
FTSE Russell confirms that OZ Minerals Ltd
has been independently assessed according
to the FTSE4Good criteria, and has satisfied
the requirements to become a constituent
of the FTSE4Good Index. The FTSE4Good
Index Series is designed to measure the
performance of companies demonstrating
strong environmental, social and governance
practices. The FTSE4Good indices are used by
a wide variety of market participants to create
and assess responsible investment funds and
other products.

Energy use and greenhouse gas emissions
The majority of OZ Minerals’ energy use
occurs at the Prominent Hill mine. The
two main areas of energy consumption
are the processing plant (electricity) and
mining vehicles (diesel fuel). Prominent Hill’s
mining activities are transitioning as the
open pit approaches the end of its life. As
mining transitions underground there will
be less waste, fewer trucks operating and
less diesel consumption.
We have reported energy use and
greenhouse gas emissions in line with
National Greenhouse and Energy
Reporting Scheme (NGERS):
/ Overall Scope 1 emissions decreased
by 26 per cent compared to the
previous year
/ Diesel use is Prominent Hill’s primary source
of Scope 1 greenhouse gas emissions
/ 300,000 tonnes of Scope 1 and
Scope 2 carbon dioxide equivalent
emissions were generated in total,
a 15 per cent reduction compared
to the previous year.
OZ Minerals is committed to reducing
the energy intensity of our operations;
developing innovative practices in relation
to chemical processing; and being more
efficient in our transportation and processing
activities. A statement on OZ Minerals’
climate change risks is provided on page 35.

Air quality
Dust is the main air emission relevant to
our assets. It is generated by stockpiling
and moving materials with vehicles that
are driven on unsealed surfaces. We use
a range of control measures to reduce the
amount of dust we generate, including
regular road maintenance and speed
restrictions. We have verified that air
quality management has effectively
prevented adverse impacts on workers,
the community and the environment,
through comprehensive sampling at
Prominent Hill and Carrapateena. There
are no ozone-depleting substances,
persistent organic pollutants or stack
emissions produced at Prominent Hill and
Carrapateena. Air quality is also affected
by sulphur and nitrogen oxides that are
generated by burning fuels. During blasting,
gases like carbon monoxide and oxides of
nitrogen are generated.

Water
Prominent Hill and Carrapateena are situated
in areas with an average annual rainfall
of less than 200 millimetres per year and
they depend on groundwater to sustain
operations. Our wellfields are located on
nearby pastoral stations and, in the majority
of cases, the pastoralists draw water from
a shallower or discrete aquifer. Our water
monitoring program monitors water levels
and quality in previously-agreed pastoral
wells on neighbouring stations. We closely
monitor the surrounding groundwater
sources and report these results to the
relevant stakeholders. To ensure our control
measures are effective, we conduct ongoing
surface water monitoring to detect any
potential changes in downstream surface
water quality from baseline values, including
acidity, salinity and water level.
Waste
Waste is managed on site at the integrated
waste rock and tailings storage facility at
Prominent Hill. Over the reporting period,
Prominent Hill produced six million tonnes
of waste rock and eight million tonnes of
tailings. No potential acid-forming (PAF)
material was mined. Most of the waste rock
generated is placed in the rock dumps, with
a proportion of non-acid forming (NAF) rock
used to construct mine infrastructure, such
as the tailings storage facility and roads.
When PAF rock is encountered, it is
encapsulated in designated PAF cells
within the waste landform. These PAF
cells are then encapsulated within NAF
rock to prevent surface water runoff
using physical control measures to
prevent impact to the environment.
Our tailings performance standard sets out
our approach to manage waste within the
Tailings Storage Facility (TSF). These standards
are written to ensure the TSF is designed,
constructed and managed to achieve the
following outcomes: prevent seepage rates
to groundwater, ensure that the tailings
are both physically and chemically stable,
be protective of terrestrial and avian life,
and comply with regulatory and licence
requirements. The facility is run under a
TSF Operations Management Plan which
has been developed to comply with these
standards.
As part of our tailings management,
we conduct water sampling to monitor
parameters including depth to water, salinity,
pH, and metals at and surrounding the
tailings storage facility and open pit.

Land and biodiversity
Prominent Hill has formal management and
monitoring plans for two bird species, the
chestnut-breasted whiteface and the thick-
billed grasswren (eastern subspecies). Both
of these species are on the International
Union for Conservation of Nature (IUCN)
Red List of Threatened Species. OZ Minerals
has established a Significant Environmental
Benefit (SEB) offset area to protect and
enhance the birds’ habitat.
At Carrapateena, three IUCN species are
listed within the area – two vulnerable
species (the Malleefowl and plains rat) and
one endangered species (Pernatty knob-
tailed gecko). The plains rat is the only
species within the local area of proposed
operations. Our monitoring continues to
indicate that mining activities will have
minimal impact on the surrounding natural
environment.

Rehabilitation and closure
OZ Minerals’ operations have conceptual
mine closure plans and several documents
and programs detailing closure, including the
Supporting Works Plan and the Program for
Environment Protection and Rehabilitation.
The Supporting Works Plan is reviewed
annually to ensure closure assumptions are
in line with current operational activities.
The documents include rehabilitation and
closure completion criteria to achieve post-
mining designated land use and to minimise
environmental liability. A mine’s closure
plan is updated throughout its operational
life so that the risks and unknowns are
identified and reduced over time. We provide
for the estimated costs of rehabilitating,
decommissioning and restoring the areas
disturbed during the mine’s operation.
SU STAINABILITY IN PRACTICE
Progressive rehabilitation has been taking
place at Prominent Hill. With the imminent
closure of the open pit, rock armouring of
the north dump was completed during the
year and rock armouring of the south dump
was 97 per cent complete at year’s end.
Stakeholder engagement on mine
closure occurs throughout a mine’s life.
The potential social and environmental
impacts of mine closure are considered in
our conversations with governments and
local communities. We keenly support
community initiatives and sustainable local
businesses as a part of our community
engagement program.

Energy efficiency program
at Prominent Hill
OZ Minerals conducted an energy efficiency
audit at Prominent Hill with support
from the South Australian Government
Energy Productivity Program. Two energy
productivity opportunities were identified
as immediate opportunities and will form
part of our energy program in 2018. The
initiatives will improve the energy efficiency
of our mining operation and reduce
greenhouse gas emissions.
We are committed to developing and
shaping a modern energy landscape for
all our mining operations. A company-wide
power strategy is being developed and will
be released in Q1 2018.

Stakeholder engagement
We seek to build and maintain strong,
supportive relationships with the local
communities where we operate. Our assets
have community engagement programs
that include engagement with regulatory
bodies, government agencies, communities,
land owners, traditional owners and local
pastoralists within the sphere of influence
of the operational and project activities.
These programs ensure input from the local
community and government and provide
the opportunity for us to understand
the environmental, social and economic
implications of our projects.
We also engage with key community groups
and stakeholders who may potentially be
affected by the asset’s activities to better
understand the risks and social impacts.
We provide accurate and relevant
information in a timely manner, and
anticipate and proactively address
community and stakeholder issues and
concerns when consulting with them.
Mechanisms are in place to capture
complaints and grievances and ensure they
are promptly addressed. Our assets also
monitor and review major communications
and consultation activities to assess their
effectiveness and promote employee and
external stakeholder feedback.

Socioeconomic contributions
We make significant contributions to local,
regional and national economies directly
through the payment of taxes and royalties
to governments, as well as payments to
our workforce and suppliers. In 2017 we:
/ paid more than $56.0 million in
wages and benefits
/ spent $736 million on goods
and services
/ contributed approximately $52.9 million
in royalties.
Activities at Prominent Hill and
Carrapateena significantly contributed
to local and regional economies in
South Australia, by $161 million in total.
Operationally, significant value is generated
through employment with our contracting
partners and ourselves, 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.

Socioeconomic data table, p. 75
Community investment and sponsorship
We have contributed to a broad range of
local and regional programs. In addition
to funding, our employees and contract
partners provided in-kind assistance through
the donation of 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
community’s wishes. Our sponsorships and
community investment initiatives strive to
support organisations or projects to achieve
sustainable outcomes.
Community investment
We contributed $0.27 million to sponsorship
of local organisations and programs in 2017,
including the Royal Flying Doctor Service
(see also Sustainability in practice on page
70), SA School of the Air, Coober Pedy Area
School and the Umoona Tjutagku Health
Service. We have assisted the sustainability of
our smaller host communities by sponsoring
key local events in communities including
Coober Pedy, Carrieton, Glendambo, William
Creek, Oodnadatta and Marree.

Our greatest supply impact is through
contracting mining and other services.
The largest material inputs include diesel
fuel, explosives, grinding media used in
the processing plant, and cement used in
the underground mine. These materials are
sourced from large, reputable organisations
with operations in Australia.
At the Carrapateena project, where
construction is currently ramping up, we
have employed a community relations
team to engage with local businesses
and communities and encourage local
participation. We are also collaborating with

content activities and facilitate connecting
local businesses to the Carrapateena project
supply chain.
Tax transparency
The Board of Taxation’s voluntary Tax
Transparency Code (TTC) was endorsed
by the Australian Government in 2016
and is designed to encourage greater
transparency within the corporate sector
of its compliance with Australian tax laws.
We support the initiative to ensure Australian
businesses and subsidiaries of multinational
companies operating in Australia pay tax
on their profits, as required under Australian
tax legislation.
Local procurement
We seek to create sustainable benefits for
the regions around our assets and source
local employees and suppliers where possible.
We preferentially purchase goods and services
locally, within the region or within the state.
National or international procurement is
only considered when local procurement is
not available or not competitive. We also
help local businesses to understand our
pre-qualification processes and procurement
standards. Local and Aboriginal and Torres
Strait Islander peoples are encouraged to
apply for positions and tender for business
opportunities with our assets.
In 2017, OZ Minerals’ spent $161 million
with South Australian regional and local
suppliers and contractors. These figures do
not include wages and salaries paid to major
contractors or expenditure by contractors
in the local region.

Indigenous peoples and cultural heritage
A genuine partnership with land-connected
Aboriginal and Torres Strait Islander peoples
is built on trust, respect and integrity. It
allows us to build a common understanding
and language, identify opportunities, learn
from each other and work towards shared
goals. A comprehensive understanding
of the culture and social structure of host
communities is required to ensure respectful,
inclusive and effective engagement. Each
asset has dedicated personnel to ensure
regular liaison with Indigenous communities.
The requirements regarding engagement
with Indigenous communities are set out
in the Land-Connected Indigenous Peoples
Performance Standard. In line with the
standard, each asset must operate in
accordance with the principles of the UN
Declaration of the Rights of Indigenous
Peoples (UNDRIP). Our partnering approach
with Indigenous peoples is based on
principles of equality, transparency and
mutual benefit. It respects and protects
the rights of Indigenous peoples and is in
line with the values of ‘Free prior and
informed consent’.
Ethics and human rights
Our internal governance is guided by
international guidelines, such as the UN
Guiding Principles on Business and Human
Rights, United Nations Universal Declaration
on Human Rights, Voluntary Principles on
Security and Human Rights, International
Labour Organisations Conventions and
the International Council on Mining and
Metals principles. We further reinforce our
expectations of employees through our Code
of Conduct. We have a variety of programs
to promote a culture of compliance
and ethical business. Asset induction

We provide cultural heritage and awareness
training and information on how to avoid
damage to cultural heritage, along with
project obligations and requirements.
Cross-cultural awareness training programs
are offered to employees and selected
contractor representatives at Prominent
Hill, with a new training program under
development specifically for Carrapateena
operations. The training includes raising
awareness on heritage and artefact finds and
working in areas of cultural significance.
Prominent Hill continues to actively engage
with the Antakirinja Matu – Yankunytjatjara
traditional owners to collaborate on matters
of shared ownership and shared value,
such as cultural heritage management
and cultural awareness training for OZ
Minerals employees and contractors. We
also support training programs, identify
employment opportunities and identify
business development programs.
training raises awareness of human rights
responsibilities with senior management,
employees, contractors (particularly
security forces and human resources), and
other stakeholders in the asset’s sphere of
influence. From time to time, we also provide
our employees with training on topics
covered within the human rights standards.
Maintaining and improving our systems
and processes helps to ensure there are no
human rights violations in our operations or
in our supply chain.

Keeping the future good for all of us
The relationship between OZ Minerals and the traditional owners of the
land where we operate is critical to the long-term success of our operations.
The Kokatha people are the traditional owners of a large section of the
land in South Australia’s north, including land on which the Carrapateena
project is located. OZ Minerals and the Kokatha Aboriginal Corporation
developed a Partnering Agreement which provided the basis for a Native
Title Mining Agreement for the Carrapateena project. This informs and
underpins the relationship and determines the nature, parameters and values
of the partnership over the mine’s life and beyond. The partnering approach
adopted by OZ Minerals and the Kokatha Aboriginal Corporation is based
on principles of equity, transparency and mutual benefit.
“This approach makes us partners, working together to co-design solutions.
While this process is more challenging to undertake than transactional
partnering, it offers far greater strategic value. Our partnering agreement
NGANAMPA PALYANKU KANYINTJAKU translated, means keeping the
future good for all of us in Kokatha. This encapsulates the outcome of
the process and the feelings of my community.” Chris Larkin, Chairman,
Kokatha Aboriginal Corporation

Safety culture and leadership
We understand that mining activities
may involve additional hazards which can
impact people’s safety. We’re committed
to identifying, evaluating and managing all
of the associated threats for the actual and
potential adverse impacts of mining activities
as far as reasonably practicable.
Our target is to achieve an injury and
occupational disease-free workplace,
by ensuring hazards are identified and
managed at the source. All safety incidents
are thoroughly investigated, we share what
we’ve learned and we implement corrective
action. Safety data is collected for the entire
workforce, including employees, contractors
and visitors working on our sites, and it is
reported to management, including to the
Managing Director and Chief Executive
Officer. We also conduct yearly internal
audits against select company processes
and standards.
Active engagement from our senior
leadership, combined with activities
focused on identifying and eliminating
causes of incidents. However, Carrapateena
experienced an increase in recordable
injuries during ramp-up of work in 2017.
Significant incidents and incident trends are
comprehensively reviewed by the Board’s
Sustainability Committee, to ensure we
learn from incidents, we comply with our
approved processes, and we implement
additional controls where necessary.
Safety programs
Effective safety management means we:
/ provide a safe working environment
with supportive processes and systems
/ empower our workforce to raise
safety issues before there is potential
for an incident
/ thoroughly investigate incidents when
they occur
/ implement controls to prevent the
likelihood of reoccurrence using sound
risk management practices.
Safety statistics are calculated per one
million working hours. In 2017, the total
recordable injury frequency rate (TRIFR) per
million hours worked decreased from 6.80
in 2016 to 6.39.
Our lead indicators are monitored to reduce
workplace hazards and injuries. Incidents
with potential or actual consequences are
internally rated and assessed for their
impact on safety, health, environment,
community and financial metrics. This
classification helps us to identify significant
incidents that warrant an in-depth review
and analysis. Significant incidents are those
deemed to have:
/ potential or actual consequences
rated at level four or above
/ actual consequences rated at level four
or above for injury and illness incidents
and at level three and above for all other
incident types.
Potential and actual significant safety
incidents are thoroughly investigated
using the incident–cause–analysis method.
In 2018, we will continue our focus on
health and safety communications, with
visible leadership, accountability and
continuous reinforcement from all levels of
management. This will help to drive a strong
safety culture.
We have a number of initiatives in place
to mature our safety culture. Our focus is
on developing strong leaders and promoting
safety leadership across our business and
with our contracting partners. All of 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 accidents, injuries and illnesses.
Our key safety programs include a Critical
Risk Program and Byrnecut’s Under Ground
Safety Improvement Program.
In 2018, we will
continue our focus
on health and safety

Contractor management
Our projects are delivered in partnership
with contractors and suppliers, and we
rely in part on their capabilities to carry out
our operations. Our management system
defines the requirements and practices for
working with contractors and suppliers.
Major contractors sign agreements with
requirements consistent with our Code of
Conduct, policies and standards. They must
share our values and exhibit behaviour that
ensures the safety of the workforce.
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 performance criteria (safety
and environment) and performance criteria
(including operating performance and site
management) are developed and applied
to our contracts.
Major contractors
must share our values
and exhibit behaviour
that ensures the safety
of the workforce.
Training and emergency preparedness
We offer a wide range of development
opportunities including formal programs,
technical and compliance training, online
learning and mentoring. This year, our
workforce undertook 11,363 hours of
employee training, mostly at Prominent
Hill where the greatest number of our
employees are based.
Our crisis management procedures detail
the roles, responsibilities and processes our
corporate crisis management team would
follow in the event of a crisis. The team
includes representatives from operations,
legal, commercial, safety, environment,
community, media and government relations.
We define a crisis as an event that seriously
threatens people, operations, assets, the
environment or our long-term prospects and
reputation. Our assets have specific crisis
management plans that outline the response
to be initiated in the event of a crisis. We
hold regular crisis training events and
simulation exercises involving both the mine
and the corporate crisis management teams.

Royal Flying Doctor Service
OZ Minerals is proud to be an ongoing
financial supporter of the Royal Flying
Doctor Service (RFDS). The RFDS is an
invaluable support in times of need as
our assets and exploration projects are
located in remote and regional locations
with limited infrastructure and access.
In 2016–17, the RFDS central operations
conducted over 320 aeromedical retrievals
for emergency evacuations and primary
health care in the communities surrounding
Prominent Hill. The RFDS has been saving
lives in outback Australia for 90 years,
retrieving the critically ill or injured and
providing urgent transfers of patients
between regional and metropolitan
hospitals to higher levels of care.

People and performance
In 2017, we changed the name of our
human resources department to People
and Performance. This better reflects our
focus on innovation and recognises that our
people drive performance, which is central
to OZ Minerals’ success.
“This is part of being a modern mining
company. This change to People and
Performance reinforces our strategy
and How We Work Together principles. By
demonstrating these principles, we enable
growth, innovation and collaboration.”
Mark Rankmore, OZ Minerals’
Head of People and Performance.
Health and wellbeing programs
We have implemented a series of programs
that promote, maintain and enhance a
healthy lifestyle, in view of the impact of
physical, mental, emotional and social
health on overall employee wellbeing.
Our fitness-for-work program includes a
wide range of activities and education in
fatigue management, employee assistance
programs, role-based assessments,
ergonomic assessments, fitness, and drug
and alcohol programs. We intend to provide
employees with the necessary education
and information to self-manage their own
fitness-for-work. All our workplaces have a
zero alcohol and drug policy.
Mental health is an important health risk that
continues to be a concern across the mining
industry. We offer an employee assistance
program (EAP) with free, professional and
confidential counselling to all employees,
contractors, and their immediate family
members. The EAP is provided through a
leading global health and wellness company
and helps to address work or personal issues
through a network of accredited counsellors.
We offer an array of benefits to our
employees including performance-based
incentive plans, career development
opportunities, paid parental leave and
health and wellbeing services, such as health
insurance, medical check-ups and health
education programs.

Ethical conduct training
Employment
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 open pit mining contractor is gradually
demobilising as Prominent Hill transitions
to an underground-only operation in
2018. This transition will have an impact
on the number of people working at the
mine and we are supporting the affected
personnel with redeployment opportunities,
redundancy packages and outplacement
services. The greatest impact will be on the
open pit mining contracting company and
its employees.

Diversity and inclusion
Women comprise 20 per cent of the
workforce directly employed by OZ Minerals.
Some individual contributors and functional
leadership areas have more than 23 per cent
female representation.
All employees are entitled to parental leave.
In 2017, four women took parental leave
and three returned to work after their
parental leave had ended. A retention rate of
85 per cent was maintained after 12 months.
We offer competitive remuneration for
our employees that reflects the job type,
years of experience, and the length of time
employees have held their position. We
review earnings annually by gender and
job band level to make sure that employee
remuneration remains equitable and in line
with market trends.
Twenty five per cent of our total workforce is
covered by collective bargaining agreements.
We value diversity in our workforce as it
helps us innovate and do things differently.
We believe diversity and inclusion provides
us with a strategic advantage that stems
from applying a variety of capabilities,
ideas and insights into problem solving
and decision making.

Criteria Used as the Basis of Reporting
The criteria used in relation to the Sustainability Report content are the GRI G4
Sustainability Reporting Guidelines published by the Global Reporting Initiative (GRI) and
Company-specific definitions.
Basis for Conclusion
We conducted our work in accordance with Australian Standard on Assurance
Engagements ASAE 3000 (Standard). In accordance with the Standard 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 Limited personnel to understand the internal controls,
governance structure and reporting process of the Selected Sustainability Information;
/ reviews of relevant documentation;
/ analytical procedures over the Selected Sustainability Information;
/ site visits to Corporate Head Office (Adelaide) and Prominent Hill mine site;
/ walkthroughs of the Selected Sustainability Information to source documentation;
/ agreeing the selected information included in the Sustainability Report 2017 to
relevant underlying sources on a sample basis for mine closure;
/ agreeing the selected claims included in disclosures to source documentation
/ an assessment that the indicators reported were in accordance with the GRI G4
Core level of disclosures
/ reviewing the Sustainability Report in its entirety to ensure it is consistent with our
overall knowledge of the assurance engagement.

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.

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:
/ Determine that the criteria is appropriate to meet the needs of intended users, being OZ
Minerals Limited and their stakeholders.
/ Prepare and present the information subject to assurance in accordance with the criteria.
This includes disclosing the criteria, including any significant inherent limitations.
/ Establish 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.
/ Tell us of any known and/or contentious issues relating to the information subject to
assurance.
/ Maintain 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 2017, and to issue an assurance
report that includes our conclusion.

Prominent Hill 2017 Mineral Resources and Ore Reserves
The Prominent Hill Mineral Resource as at 30 June 2017 has been estimated at 163 million
tonnes of copper-gold mineralisation grading 1.0 percent copper, 0.7 grams per tonne gold
and 2.7 grams per tonne silver. The Mineral Resource contains 7% fewer copper tonnes
and 6% fewer gold ounces than the previous Mineral Resource estimate.
Open pit mineral resources
/ The Prominent Hill Open Pit Mineral Resource estimate decreased by 14 million tonnes
(64 per cent), 140 thousand tonnes of copper metal (62 per cent) and 290 thousand
ounces of gold metal (66 per cent) as a result of mining depletion.
Underground mineral resources
/ The Prominent Hill Underground Mineral Resource estimate decreased by 1.4 million tonnes
(1 per cent), 30 thousand tonnes of copper metal (2 per cent) and 70 thousand ounces
of gold metal (2 per cent). However relative to the 2016 estimate, the estimated Mineral
Resource has now increased in confidence with increased Measured (+15%) and Indicated
(+23%) classified material tonnages and decreased Inferred (-17%) classified material
tonnage.
/ Diamond drilling activities, mostly in the southern Prominent Hill Shear Zone and Volcanics,
resulted in the addition of approximately 3 million tonnes of new copper mineralisation at
1.2 per cent copper and 0.7 grams per tonne gold to the Mineral Resource, predominantly
into the Measured and Indicated estimation classifications. In addition, drilling also
upgraded approximately 5 million tonnes of existing 2016 Inferred Mineral Resource
estimation to the Measured and Indicated estimation classification in 2017.
/ Additional tonnage due to diamond drilling fully offset underground mining tonnage
depletion for the twelve month period. Reductions in the estimated Inferred Mineral
Resources were driven by re-evaluated geological and grade continuity interpretations,
influenced by updated diamond drilling information, changes to the NSR calculation’s metal
recoveries and updated estimation parameters.
Stockpiles
/ Surface ore stockpiles as of 30 June 2017 had increased by 6.8 million tonnes (30 per cent),
45 thousand copper metal tonnes (68 per cent) and 140 thousand gold ounces (33 per
cent). 6.7 million tonnes (98 per cent) of the stockpile growth was directly attributable to
Open Pit ore mining.

Prominent Hill Ore Reserves
The Ore Reserves at 30 June 2017 were
estimated to be 74 million tonnes at 1.0
percent copper and 0.6 grams per tonne
gold for 730 thousand tonnes of contained
copper and 1.5 million ounces of contained
gold. The 2017 Ore Reserve contains 1%
less copper tonnes than the previous Ore
Reserve estimate.
Open Pit Ore Reserves
/ The Ore Reserves decreased due to
mining depletion almost exclusively.
Underground Ore Reserves
/ Underground Ore Reserve copper and
gold metal has increased by ~13 and
~27 per cent respectively, driven by
increased confidence in the Mineral
Resource estimate, improved design
inputs and lateral (across and along
strike) mining area expansions.

The Mineral Resource statement includes additional drilling from 2016 which focused on the
upper part of the deposit between 4200mRL – 4600mRL. The aims of the drilling were to
confirm grade and geological continuity across the deposit and upgrade a proportion of the
Mineral Resource to Measured Resources.
The differences in resource tonnages and grades between the November 2016 Mineral
Resource and the October 2016 Mineral Resource are immaterial although the November
2016 Mineral Resource has a higher level of confidence.

Carrapateena Ore Reserves
The Pre-feasibility Study and Ore
Reserve estimate has been updated for
the 2016 Mineral Resource Estimate as at
18 November 2016. The update includes
a revision to the mine access and material
handling system, and modifications to the
mining footprint where required. Based
on the mining and processing schedules
completed for the study update, together
with ongoing metallurgical test-work, the
Carrapateena Project is no longer reliant
on the incorporation of a Concentrate
Treatment Plant (CTP), and has not
been included.

/ include general purpose Financial
Statements prepared by a for profit entity
in accordance with Australian Accounting
Standards (‘AASBs’) and the Corporations
Act 2001, and comply with International
Financial Reporting Standards (‘IFRS’)
/ are presented in Australian dollars which
is also the functional currency of the
Company and all its controlled entities
/ 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
/ investments in equity securities
/ derivative financial instruments
Recognition and measurement of revenue
Revenue from sale of concentrates is recognised upon transfer of risks and rewards to the
customer when the price is fixed or determinable, no further processing is required, the
quantity and quality of the goods has been determined with reasonable accuracy, and
collectability is probable. This is generally when the concentrates are loaded on to the vessel
at the port of shipment or in the case of domestic sales when the concentrates are delivered
to the customer’s premises.
Measurement of sales revenue is based on the most recently determined estimate of product
specifications with a subsequent adjustment made to revenue upon final determination of
metal content in concentrates by customer. These adjustments are typically insignificant
relative to the total sales value.
The terms of concentrate sales contracts contain provisional pricing arrangements. The
commodity price for metal in concentrate is based on prevailing prices at the time of
shipment to the customer. Adjustments to the commodity price occur based on movements
in quoted market prices up to the date of final settlement. Receivables arising from sales
contracts are initially recognised at fair value, with subsequent changes in fair value
recognised in the Income Statement in each period until final settlement, as an adjustment
to revenue. Changes in fair value over the quotation period and up until final settlement are
estimated by reference to forward market prices.
Revenue is reported net of treatment and refining charges, other commercial costs, pricing
adjustments, and gains/losses from copper derivative contracts.
net Revenue by geographical region
/ items of inventory and property, plant
and equipment which have been written
down in accordance with applicable
accounting standards.
Other than the final dividend for the year
ended 31 December 2017, as discussed in
Note 4, no events have occurred subsequent
to reporting date which have significantly
affected or may significantly affect the
Consolidated Entity’s operations or results
in future years.

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

RE C OVERABILITY OF
DE FE RRED TAX ASSETS
The Consolidated Entity is subject to income
taxes of Australia and jurisdictions where it
has foreign operations. Significant judgement
is required in the application of income tax
legislation to determine the provision for
income taxes. There are many transactions
and calculations undertaken during the
ordinary course of business for which the
ultimate tax determination is uncertain, and
for which provisions are based on estimated
amounts. Where the final tax outcome of
these matters is different from the amounts
that were initially recorded, such differences
will impact the current and deferred tax
provision in the period in which the
determination is made.
Assumptions about the generation of future
taxable profits influence the ability of the
Consolidated Entity to recognise (or continue
to recognise) deferred tax assets. Taxable
profit estimates are based on estimated
future production and sales volumes,
commodity prices, foreign exchange rates,
operating costs, restoration costs and capital
expenditure. A change in these assumptions
may impact the amount of deferred tax
assets recognised in the balance sheet in
future periods.

Recognised restricted tax losses are subject to an available fraction which limits the amount of these losses that can be utilised each
year and may only be utilised after unrestricted tax losses are utilised.
Unrecognised tax losses
During the year, a review of unrecognised tax losses was undertaken and as a result no
additional restricted tax losses were recognised in the Balance Sheet. Restricted tax losses of
$178.1 million tax effected (2016: $178.1 million tax effected) remain unrecognised in the
Balance Sheet at 31 December 2017. Capital tax losses of $595.0 million tax effected (2016:
$592.5 million tax effected) remain unrecognised in the Balance Sheet at 31 December 2017.

Recognition and measurement of income taxes
Current tax
The tax currently payable is based on taxable profit for the year, using rates enacted or
substantively enacted at reporting date, and any adjustments to tax payable in respect of
previous years.
Deferred tax
Deferred tax assets and liabilities are determined using the balance sheet method which
calculates temporary differences based on the difference between the carrying amount of the
Consolidated Entity’s assets and liabilities in the balance sheet and their associated tax bases.
Deferred tax assets and liabilities are not recognised for temporary differences arising from
investments in subsidiaries where the consolidated entity is able to control the reversal of
the temporary differences, and it is probable they will not reverse in the foreseeable future.
Deferred tax assets are recognised to the extent that it is probable that future taxable income
will be available to utilise them.
The carrying amount of deferred tax assets is reviewed at the end of each reporting date and
adjusted based on estimates of future taxable income and or capital gains against which the
deferred tax asset could be utilised.
Deferred tax assets and liabilities are measured at the tax rates applicable to each jurisdiction
which are expected to apply in the period when the assets are realised or liabilities discharged
and are offset where they relate to the same tax authority and there is a legally enforceable
right to offset.
4. Dividends
Since the end of the financial year, the Board of Directors has resolved to pay a fully franked
dividend of 14 cents per share, to be paid on 26 March 2018. The record date for entitlement
to this dividend is 12 March 2018. The financial impact of the dividend amounting to $41.8
million has not been recognised in the Consolidated Financial Statements for the year ended
31 December 2017 and will be recognised in subsequent Consolidated Financial Statements.

5. Inventories
Inventories are recognised at the lower
of cost and net realisable value (‘NRV’).
Net realisable value of ore is based on
the estimated amount expected to be
received when the ore is processed and
sold, less incremental costs to convert the
ore to concentrate and selling costs. The
computation of net realisable value 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 net
realisable value and may therefore impact
the carrying value of inventories.

An assessment of the net realisable value of non-current ore resulted in an adjustment to increase
the value of inventory by $16.8 million in respect of low grade gold ore stockpiles being recognised
in 2017 (2016: reduce by $10.5 million). The increase is a reversal of previous impairment.
Recognition and measurement of inventories
Inventory is valued at the lower of cost incurred in bringing product to its present location
and condition and net realisable value.
Costs are assigned to individual items of inventory on the basis of weighted average costs.
Cost comprises direct materials and labour, and a proportion of overhead expenditure directly
related to the production of inventories. Expenditure directly related to the production
of inventories includes processing costs, transportation costs to the point of sale, and
depreciation of plant and equipment and mining property and development assets, the latter
of which includes deferred stripping assets and mine rehabilitation costs incurred in the
mining process.
Net realisable value is calculated by estimating the value that is expected to be realised upon
sale of concentrate after deducting estimated costs of processing, and selling costs. This
estimation is based on assumptions of future prices and costs, as well as expected future ore
blend rates and timing of processing.
Inventories expected to be processed or sold within twelve months after balance date are
classified as current assets, all other inventories are classified as non-current.

The original acquisition of Carrapateena provided for two further payments upon commercial
production being reached.
/ US$50 million on production of copper, uranium, gold or silver.
/ US$25 million on production of rare earths, iron or any other commodity.
The further payments amounting to US$75 million do not constitute a liability and are not
recognised in OZ Minerals balance sheet because OZ Minerals ha not reached the specified
performance milestones on which payment is required.
Recognition and measurement of property, plant and equipment
Items of property, plant and equipment are stated at cost less accumulated depreciation
and accumulated impairment losses. Cost includes expenditure that is directly attributable
to the acquisition of the items and costs incurred in bringing assets into use.
Mine property and development assets include costs transferred from exploration and
evaluation assets once technical feasibility and commercial viability of an area of interest
are demonstrable. After transfer, all subsequent expenditures to develop the mine to the
production phase which are considered to benefit mining operations in future periods
are capitalised.
The proceeds from sale of any concentrate produced from ore extracted and processed as
part of development of the asset prior to it being deemed ready for use, less any further
processing and selling costs incurred, is deducted from the cost of the asset.
The present value of the expected cost of decommissioning an asset after its use is included
in the cost of the respective asset if the recognition criteria for a provision are met.

RE C OVERABILITY
OF A SSETS
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 and Carrapateena CGU’s to
determine whether there was any indication
that these CGU’s had suffered an impairment
loss. The Consolidated Entity concluded that
there was no such indicators that either CGU
was impaired at reporting date.
In reviewing for impairment indicators,
the group assessed for negative trends in
the significant judgements and assumptions
which may impact the CGU’s valuation in
future periods, including:
/ Future cash flows based on 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, operating and capital costs.
/ The value of Mineral Resources not
modelled in Board approved budgets
based on the use of an appropriate
resource valuation multiple to the
contained copper equivalent within
the Resources applicable to the CGU.
/ The discount rate applied to the cash flows
which reflects current market conditions.
In addition, the Consolidated Entity
monitors for impairment indicators by
considering the impact of the above
judgements and assumptions on the
valuation of CGU’s 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 CGU’s may differ in future years
if assumptions made do not eventuate
and actual outcomes are less favourable
than present assumptions.
Property Plant and Equipment is tested for impairment when there is an indication of
impairment. For the purposes of assessing impairment, assets are grouped at the lowest levels
for which there are separately identifiable cash inflows. An impairment loss is recognised for
the amount by which the asset or Cash Generating Unit (CGU) carrying amount exceeds its
recoverable amount. The recoverable amount is the higher of an asset’s fair value less costs to
dispose and value in use. Assets that have been impaired are reviewed for possible reversal of
impairment at each reporting date.
Value in use is the net amount expected to be recovered through cash flows arising from
continued use and subsequent disposal of an asset (or group of assets). In assessing value
in use, estimated future cash flows are discounted to their present value using a pre-tax
discount rate that reflects current market assessments of the time value of money and risks
specific to the asset.
The asset’s fair value less costs to dispose is the amount obtainable from the sale of an asset
or cash-generating unit in an arm’s length transaction between knowledgeable, willing
parties, less the estimated costs of disposal.
A fair value measurement of a non-financial asset takes into account a market participant’s
ability to generate economic benefits by using the asset in its highest and best use or by
selling it to another market participant that would use the asset in its highest and best use.
The depreciation methods adopted by the Consolidated Entity are provided
in the table below:
Category
Freehold land
Depreciation method
Not depreciated
Buildings and other infrastructure
Straight line over life of mine
Short term plant and equipment
Straight line over life of asset
Processing plant
Units of ore milled over mining inventory
Mine property and development
Units of ore extracted over mining inventory
applicable to the development
Depreciation of assets commences when the assets are ready for their intended use. The
depreciation of mine property and development commences when the mine is commissioned
or deemed ready for use.
The residual values, useful lives and methods of depreciation of property, plant and
equipment are reviewed at each reporting period and adjusted prospectively, if appropriate.
Where depreciation rates are changed, the net written down value of the asset is depreciated
from the date of the change in accordance with the new depreciation rate, with the change
accounted for as a change in accounting estimate.
During 2017, the useful life of mine property and development and processing plant assets
depreciated on a units of production basis were reassessed and are now based on mining
inventory (previously reserves), which includes all reserves and a portion of resources which are
expected to be mined or processed in the course of the current mine plan. This more closely
aligns to the benefits received by the assets from their use.

The estimated quantities of economically recoverable reserves and resources 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 reserves and resources estimates can impact the carrying value of
property, plant and equipment including deferred mining expenditure, intangible assets,
capitalised exploration, provisions for mine rehabilitation, restoration and dismantling
obligations, recognition of deferred tax assets, as well as the amount of depreciation
charged to the Income Statement.
Changes in the carrying value of the assets may arise principally through changes in the
income that can be economically generated from each project. Changes in depreciation
expense may arise through a change in the useful life over which property, plant and
equipment is depreciated.
CARRYING VALUE OF CAPITALISED
EXPLORATION EXPENDITURE
Exploration assets
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 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 areas of interest.

Following the decision to proceed with development of the Carrapateena mine, the Consolidated
Entity transferred the balance of exploration assets related to the Carrapateena project to Property
Plant and Equipment in accordance with the accounting policy described below.
Recognition and measurement of exploration expenditure
Exploration and evaluation expenditure is recognised in the Income Statement as incurred,
unless the expenditure 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.
Exploration and evaluation assets are classified as tangible or intangible according to the
nature of the assets. Exploration and evaluation assets are not depreciated and are assessed
for impairment if:
/ sufficient information exists to determine technical feasibility and commercial viability; or
/ other 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
CGUs 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 demonstrable, 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). Expenditure
incurred under earn-in arrangements is expensed as incurred. 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.

Assets held for sale
The Tunnel Boring Machine previously classified as Non-current Assets Held for Sale and
Discontinued Operations in accordance with AASB 5 was sold during the year.
8. Lease receivable
Recognition and measurement of finance lease receivable
Leases which transfer substantially all the risk and rewards of ownership of an asset are
classified as finance leases. Where a finance lease is provided, the item of equipment is
derecognised and the present value of the minimum lease payments receivable are recognised
as a lease receivable. Contingent rents are recognised as revenue in the period in which they
are earned.
The finance lease receivable represents the consideration paid by OZ Minerals to acquire
mining equipment which was leased back to Thiess on an interest free basis. OZ Minerals
benefits progressively over the mining services contract from reduced mining services
charges by Thiess. Upon termination of the mining services contract, any carrying value
of lease receivable is expected to be recovered by OZ Minerals from a resale of the
equipment to Thiess.
The finance lease receivable of $19.6m as at 31 December 2017 comprises $27.5m from
the comparative year, less a $7.9 million (2016: $7.3 million) amortisation charge against
the finance lease receivable during the year.
9. Provisions
MINE REHA BILITATION , RE S TO RATIO N
AND DISMA NTL IN G OBLIGATION S
The provision for mine rehabilitation includes future cost estimates associated with
reclamation, plant closures, waste site closures, monitoring, demobilisation of equipment,
decontamination, water purification and permanent storage of historical residues.
Uncertainty exists as to the amount of rehabilitation obligations which will be incurred due
to the impact of changes in environmental legislation, and many other factors, including
future changes in technology, price increases and changes in interest rates. The calculation
of these provision estimates requires assumptions such as application of environmental
legislation, plant closure dates, available technologies, engineering cost estimates and
discount rates. A change in any of the assumptions used may have a material impact on
the carrying value of mine rehabilitation, restoration and dismantling provisions.
Recognition and measurement of provisions
Provisions are measured at the present value of the best estimate of the expenditure required
to settle the present obligation at balance sheet date. The discount rate used to determine
the present value reflects current market assessments of the time value of money and the
risks specific to the liability. The increase in provisions due to the passage of time is recognised
in the Income Statement as financing expenses.
Provisions are made for the estimated cost of rehabilitation, decommissioning and restoration
relating to areas disturbed during mining and exploration operations up to the reporting date
but not yet rehabilitated. Provisions for mine rehabilitation are based on current estimates of
costs 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 twelve months) and non-current components based on the expected timing of these
cash flows.

Ordinary shares are classified as equity. Incremental costs directly attributable to the issue of new shares or options are shown in equity as a
deduction.
Shares bought and held by 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.
Shares acquired as part of an on-market share buyback programme are cancelled and presented as a deduction to issued capital, and
measured at the amount paid 2017: nil (2016:$29.9m).
12. Share-based payments
Total expenses arising from share-based payment transactions recognised during the year as part of employee benefit expenses was $5.3m

Performance rights granted under the PRPs or LTIPs are not entitled to dividends nor have voting rights. All performance rights under current
performance rights plans are automatically exercised upon vesting which is dependent upon meeting both the service condition and the
performance condition. The shares on vesting of performance rights rank equally in all respects with previously issued fully paid ordinary
shares when issued.
The fair value of services received in return for share-based payments granted during the year is based on the fair value of the performance

Recognition and measurement of share-based payments
The fair value of share-based payment transactions measured at grant date are recognised as an employee benefit expense with a
corresponding increase in equity over the period during which the employees become unconditionally entitled to the instruments. If the
employee does not meet a non-market condition, such as a service condition or internal KPI’s, any cumulative previously recognised expense
is reversed.
The fair value of the share-based payment transactions granted are adjusted to reflect market vesting conditions at the time of grant, and are
not subsequently adjusted. Non-market vesting conditions are included in assumptions about the number of instruments that are expected to
become exercisable and are updated at each balance sheet date. The impact of the revision to original estimates for non-market conditions,
if any, is recognised in the Income Statement with a corresponding adjustment to equity. Changes as a result of market conditions are not
adjusted after the initial grant date.

Risk Management
13. Financial risk management
OZ Minerals’ Group Treasury Function (‘Group Treasury’) manages the financial risks of the
Consolidated Entity. Group Treasury identifies, evaluates and manages financial risks in close
co-operation with OZ Minerals’ operating units. The Board approves principles for overall
risk management, as well as policies covering specific risk areas, such as market, credit and
liquidity risk.
This note presents information about the Consolidated Entity’s financial assets and liabilities,
its exposure to financial risks, as well as its objectives, policies and processes for measuring
and managing risks. The Consolidated Entity’s activities expose it primarily to the following
financial risks:
/ Commodity prices
/ Foreign currency exchange rates
/ Credit Risk
/ Liquidity Risk.
The Consolidated Entity holds the following financial instruments as presented on the face
of the Balance Sheet:
Carried at fair value using level
1 valuation technique (based
on share prices quoted on the
relevant stock exchanges)
Carried at fair value using level 2
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
Other receivables
Trade payables
Other payables
The carrying value of each of these items approximates fair value.
ACCOUNTING FOR INVESTMENTS
IN EQUITY SECURITIES
Investments in equity securities
The Consolidated Entity holds investments in equity instruments $18.0m (2016: $18.2m).
Judgement is required in assessing whether
power over an investee exists where the
Consolidated Entity holds less than a majority
of the voting rights. Factors considered
include rights arising from other contractual
arrangements, any contractual arrangements
with other vote holders as well as the
Consolidated Entity’s voting and potential
voting rights.
Despite holding 21.1 per cent of Toro
Energy Limited’s (‘Toro’) voting rights it
was determined that OZ Minerals does
not exert significant influence over Toro
considering the distribution of voting rights
amongst Toro’s other shareholders and
given OZ Minerals does not have board or
management representation and does not
participate in the financial or operating
policies of Toro.
Financial assets measured at fair value include investments in equity instruments which
are not held for trading. The Consolidated Entity recognises fair value changes in Other
Comprehensive Income based on an irrevocable election at initial recognition. Amounts
related to the change in fair value of equity securities are classified in Other Comprehensive
Income and are never reclassified to the Income Statement at a later date.
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 into the following categories:
/ Financial assets at fair value through Other Comprehensive Income;
/ Financial assets at fair value through profit and loss; and
/ 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. On adoption of AASB 9, the embedded derivative and the receivables are accounted
for as one instrument and measured at fair value through profit or loss and recognised in
the Income Statement as part of ‘Revenue’.
ANNUAL AND SUSTAINABILITY REPORT 2017 f InAnC I A L R ePoR
t
1 1 3
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 60 days. Other receivables are recognised initially at fair value and subsequently
measured at amortised cost using the effective interest method.
The Consolidated Entity derecognises a financial asset or part of it when, and only when,
the contractual rights to the cash flows from the financial asset expire or the financial asset is
transferred to another party without retaining control or substantially all risks and rewards of
the asset. On de-recognition of a financial asset, the difference between the carrying amount
(measured at the date of de-recognition) and the consideration received (including any new
asset obtained less any new liability assumed) and any cumulative gain or loss that had been
recognised in equity is recognised in the Income Statement.
A financial asset measured at amortised cost is assessed at each reporting date as to whether
there is any objective evidence of impairment as a result of one or more events having an
impact on the estimated future cash flows of the asset.
An impairment loss in respect of financial assets measured at amortised cost is recognised
in the Income Statement and is measured as the difference between the asset’s carrying
amount and the present value of estimated future cash flows discounted at the asset’s
original effective interest rate. The carrying amount of the asset is reduced through the use
of an allowance account.
In the event that an impairment loss is reversed, the asset’s carrying amount can not exceed
what the carrying amount would have been had the impairment not been recognised. The
amount of the reversal is recognised in the Income Statement.
Non-derivative financial liabilities
All financial liabilities are recognised initially at fair value and net of directly attributable
transaction costs. Trade and other payables represent liabilities for goods and services
provided to the Consolidated Entity prior to the end of the financial year which are
unpaid. The amounts are non-interest-bearing, unsecured and are usually paid within
30 days of recognition.
The Consolidated Entity derecognises financial liabilities when its obligations are discharged,
cancelled or expire. The difference between the carrying amount of the liability derecognised
and the consideration paid and payable is recognised in the Income Statement.
Derivative financial instruments
Recognition and measurement
Derivative financial instruments are initially recognised at fair value on the date the derivative
contract is entered into and are subsequently remeasured to their fair value at each reporting
date. Changes in the fair value of any derivative instrument are recognised in the Income
Statement, or Other Comprehensive Income, based the designation and effectiveness of the
hedge instrument.
Derivative financial instruments that have been designated as a hedge instrument 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. Formal designation of
the hedge and documentation of the relationship between the hedging instrument and the
hedged item is finalised at the inception of the transaction.
Changes in the fair value of the derivative financial instrument which has been designated
in a hedge relationship will be recognised in Other Comprehensive Income if the hedging
relationship remains effective and the underlying hedge item has not been recognised in the
Income Statement, or recognised in the Income Statement if the hedge relationship is no
longer effective or the underlying hedged item has been recognised in the Income Statement.
Any ineffective portion of changes in the fair value of derivative financial instruments
is recognised immediately in the Income Statement. The amount recognised in Other
Comprehensive Income is reclassified to the Income Statement in the same period as the
underlying item is recognised in the Income Statement.

Commodity price risk management and sensitivity analysis
The Consolidated Entity is exposed to commodity price volatility on the sale of metal in
concentrates such as copper and gold, which are priced on, or benchmarked to, open market
exchanges. OZ Minerals aims to realise the prevailing forward copper price at the time of shipment
of concentrates to customers which matches the quotation period of the underlying sale.
Gold derivative contracts
OZ Minerals has entered into gold forward contracts to manage its risk of fluctuations in
cash flows arising from forecast gold sales in US$ due to movements in gold prices and
the AUD:USD foreign exchange rates. The Company has designated these gold derivative
contracts as cash flow hedges.
The hedged gold sales represent around 54 per cent of forecast sales (gold oz.) in the
period from 2018 to 2021 and around 60 per cent of the gold contained in stockpiles at
31 December 2017. This programme is reviewed on a quarterly basis.
The forward contracts have been designated as cash flow hedges under AASB 9 and were
assessed to be fully effective in managing the underlying risk. Accordingly, a tax-effected fair
value reduction of $7.2 million (net of tax) was recognised in Other Comprehensive Loss. At
31 December 2017, contracts for 267,137 ounces of gold were outstanding with an average
strike price of $1,736 per ounce, as reflected in the chart below:

HEDGE EFFE CT IVE N E SS
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. Determination
of effectiveness requires the exercise of significant judgement regarding mine plans, sales
forecasts and recoverable metal contained in mineral resources and reserves.

Copper derivative contracts
The consolidated entity manages the exposure to volatility in copper price on completed sales
from contractual Quotation Pricing adjustments, by entering into copper derivative contracts
at the time of concentrate shipments which fix the forward price at the time of shipment.
These derivative contracts are designated as hedges and are recognised within the Income
Statement as part of ‘Revenue’. As a result of these hedges, the impact of changes in copper
price after the date of sale on the Income Statement is expected to be negligible.
Commodity price sensitivity analysis
Due to the copper price hedging activity, if copper prices were to vary, the expected impact
on the Income Statement would be negligible. As such, the below analysis focuses on
the impact of movements in gold prices, as variations in silver prices have been deemed
immaterial for the purpose of this analysis. In accordance with Australian Accounting
Standards, the sensitivity analysis is on all financial assets and liabilities deemed material to
the Consolidated Entity.

A 10% movement in gold prices, which is based on reasonably possible changes over a
financial year and reflects the variability management applies in forecasting sensitivity, results
in a $1.6 million after tax impact on the Income Statement on the trade receivables balance
of $121.9 million (2016: $69.4 million) and $0.4 million after tax impact on the derivative
financial liability of $16.3 million (2016: $11.4 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.
All OZ Minerals operations have a functional currency of Australian dollars. An entity’s
functional currency is the currency of the primary economic environment in which the entity
operates. Determination of an entity’s functional currency requires management’s judgement
when considering a number of factors including the currency that mainly influences revenue,
costs of production, and competitive forces and regulations which impact revenue. In
addition, consideration must be given to the currency in which financing and operating
activities are undertaken.
Foreign currency transactions are translated into the functional currency using exchange rates
prevailing at the date of the transaction. Foreign exchange gains and losses resulting from
the settlement of such transactions and from the translation at year end exchange rates of
financial assets and liabilities denominated in foreign currencies are recognised in the Income
Statement except for gold derivative contracts which are recognised in Other Comprehensive
Income. The carrying amount of the Consolidated Entity’s financial assets and financial
liabilities by its currency risk exposure at the reporting date is disclosed below.

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 $5.7 million, and Other
Comprehensive Income would have changed by $0.6 million (2016: after tax profit
$4.7 million, and Other Comprehensive Income $0.6 million).
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 does not have any borrowings at 31 December 2017 and therefore is
not exposed to interest rate risk on borrowings. The Consolidated Entity carries term deposits
with fixed interest rates. The effect of a change in interest rates at balance date would not
have a significant impact on the after tax profit as substantially all cash deposits have fixed
interest rate terms.
Credit risk management
Credit risk refers to the risk that any counterparty will default on its contractual obligations
resulting in financial loss to the Consolidated Entity. Counterparty credit risk arises through
sales of metal in concentrate on normal terms of trade, through deposits of cash, finance
lease receivables and derivative financial instruments.
At the reporting date, the carrying amount of financial assets in the balance sheet represents
the maximum credit exposure on cash and cash equivalents, trade receivables, other
receivables, derivative assets and lease receivables.
The credit risk on cash and cash equivalents is managed by restricting financial transactions
to banks which are assigned S&P equivalent of A-1 short term credit ratings by international
credit rating agencies and limiting the amount of funds that can be invested with a single
counterparty in accordance with OZ Minerals’ Credit Risk Management Policy.
Credit risk in trade receivables is managed by undertaking regular risk assessment and
reviewing credit limits of customers. As there are a relatively small number of transactions,
they are closely monitored to ensure risk of default is kept to an acceptably low level. Sales
contracts require a provisional payment of at least 90 per cent of the estimated value of each
sale either promptly after vessel loading or upon the vessel arriving at the discharge port.
Where applicable, sales are covered by letter of credit arrangements with approved financial
institutions.
The maximum exposure to credit risk for trade receivables at the reporting date by geographic
region of the customer was:

Major customers who individually accounted for more than 10 per cent of total revenue
contributed approximately 75 per cent of total revenue (2016: 69 per cent). These customers
also represent 89 per cent of the trade receivables balance as at 31 December 2017 (2016:
96 per cent). There have been no instances of customer default during 2017 and there are
|no significant receivables which are past due at the reporting date.
Credit risk on derivative financial instruments is managed by restricting transactions only with
counterparties who are at least Category Two members of the LME, or which are assigned
S&P equivalent of A-1 short term credit ratings by international credit rating agencies.

Liquidity risk management
Liquidity risk is the risk of encountering difficulty in meeting obligations associated with
financial liabilities. OZ Minerals manages liquidity risk by conducting regular reviews of the
timing of cash outflows and the maturity profiles of term deposits in order to ensure sufficient
funds are available to meet its obligations.
The following table reflects all contractual repayments from recognised financial assets and
liabilities at the reporting date, including derivative financial instruments. For derivative

events occur or fail to occur. Determination
of contingent liabilities disclosed in the

14. Contingencies
Bank guarantees
OZ Minerals Group Treasury Pty Ltd has provided certain bank guarantees to third parties,
primarily associated with the terms of mining leases, 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 are backed by deposits which
amounted to $52.9 million as at 31 December 2017 (31 December 2016: $34.6 million).
Presently, all guarantees are voluntarily cash backed by deposits in order to reduce the
bank fees payable, however, should the need arise all funds can be withdrawn as and
when required.
Deeds of indemnity
The Consolidated Entity has granted indemnities under Deeds of Indemnity with current and
former Executive and Non-executive Directors, former officers, the former General Counsel –
Special Projects, the former Group Treasurer and each employee who was a director or officer
of a controlled entity of the Consolidated Entity, or an associate of the Consolidated Entity, in
conformity with Rule 10.2 of the OZ Minerals Limited Constitution.
Each Deed of Indemnity indemnifies the relevant director, officer or employee to the fullest
extent permitted by law for liabilities incurred while acting as an officer of OZ Minerals, its
related bodies corporate and any associated entity, where such an office is or was held at
the request of the Company. Under these indemnities, the Company meets the legal costs
incurred by Company officers in responding to investigations by regulators and may advance
funds to meet defence costs in litigation, to the extent permitted by the Corporations Act

Warranties and indemnities
The Company has given certain warranties and indemnities to the purchasers of assets and
businesses that have been sold. Warranties have been given in relation to various matters
including the sale of assets, taxes and information. Indemnities have also been given by the
Consolidated Entity in relation to matters including compliance with law, environmental
claims, a failure to transfer or deliver all assets and payment of taxes.
Former Cambodian operations
The Australian Federal Police (AFP) advised OZ Minerals in September 2014 that it was
conducting an investigation of OZ Minerals’ 2009 acquisition of the remaining equity holding
in the Okvau exploration joint venture in Cambodia in relation to foreign bribery claims. Since
that time, the Company has been advised by the AFP that the scope of the AFP’s investigation
has been extended to OZ Minerals’ former Cambodian operations generally. OZ Minerals
understands that the AFP is continuing its investigation and OZ Minerals is continuing to fully
cooperate with the AFP. OZ Minerals has concluded that it is not probable that a present
obligation exists and, accordingly, no provision has been recognised in the balance sheet at
31 December 2017.
Other
OZ Minerals Limited and its controlled entities are defendants from time to time in other legal
proceedings or disputes, arising from the conduct of their business. OZ Minerals does not
consider that the outcome of any of these proceedings or disputes is likely to have a material
effect on the Company’s or the Consolidated Entity’s financial position.

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

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 twelve 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 twelve months from balance date and long service leave liabilities.
Other long term benefits are recognised in the provision for employee benefits and measured
as the present value of expected future payments to be made in respect of services provided
by employees up to the reporting date using the projected unit credit method. Consideration
is given to the expected future wage and salary levels, experience of employee departures
and periods of service. Expected future payments are discounted using market yields at the
reporting date on national government bonds with terms to maturity and currency that
match, as closely as possible, the estimated future cash outflows.
Transactions with related parties
A number of KMP, or their related parties, hold positions in other entities that may result in
them having control or significant influence over the financial or operating policies of those
entities. Where the Consolidated Entity transacts with the KMP and their related parties,
the terms and conditions of these transactions are no more favourable than those available,
or which might reasonably be expected to be available, on similar transactions to non-KMP
related entities on an arm’s length basis.

19. New accounting standards
(i) Changes in accounting policies and mandatory standards adopted during the year
The accounting policies applied by the Consolidated Entity in these Consolidated Financial Statements are consistent with those applied
by the Consolidated Entity in its Annual Report for the year ended 31 December 2016. The Consolidated Entity has adopted all of the
new, revised or amending standards that are mandatory. The adoption of these new and revised Australian Accounting Standards has not
had a significant impact on the Consolidated Entity’s accounting policies or the amounts reported during the year.
(ii) Early adoption of Standards
The Consolidated Entity has not early adopted any standards in the Annual Report during the year ended 31 December 2017.
During 2016 the Consolidated Entity elected to early adopt AASB9 Financial Instruments.
(iii) Issued Standards and pronouncements not early adopted
At the date of authorisation of the Financial Statements the following has been issued but were not yet effective.
AASB 15 Revenue from Contracts with Customers
AASB 15 changes the timing (and in some case, the quantum) of revenue recognised from customers. Currently revenue for domestic sales
is recognised when the concentrates are delivered to the customers’ premises, which is the point when the customer takes over the risk and
rewards of ownership transfer. The Consolidated Entity’s assessment indicates that under AASB 15, revenue will continued to be recognised
on the same basis when the customer obtains control of the concentrates.
Revenue for export sales is currently recognised when shipments of concentrates are loaded on to the vessel as the risk and reward of
ownership is transferred to the customer at that point. The Consolidated Entity’s assessment under AASB 15 indicates that the export
contracts are made up of two performance obligations. The first obligation to deliver the concentrates to the port of shipment and the
second obligation is to organise shipping of the concentrate, which will be satisfied when concentrates are delivered to the destination port.
The Consolidated Entity assessed that revenue relating to the first obligation of delivery of the concentrates to the port of shipping will be
recognised at that point and revenue relating to the shipping obligation will be recognised in future periods upon delivery of concentrates.
On the basis of the above the new standard is not expected to materially impact the Consolidated Entity’s net profit after tax. The
Consolidated Entity will adopt this standard effective 1 January 2018.
AASB 16 Leases
AASB16 eliminates the distinction between operating and finance leases and brings all leases (other than short term and low value leases)
onto the balance sheet. The standard does not apply mandatorily before 1 January 2019. The Consolidated Entity is currently undertaking
an analysis of transition options and the on-going financial reporting impact.

Independent
Auditor’s Report
Report on the audit of the Financial Report
To the shareholders of OZ Minerals Limited
Opinion
We have audited the Financial Report of the Consolidated Entity.
In our opinion, the accompanying Financial Report of OZ Minerals Limited is in accordance
with the Corporations Act 2001, including
/ giving a true and fair view of the Consolidated Entity’s financial position as at
31 December 2017 and of its financial performance for the year ended on that date; and
/ complying with Australian Accounting Standards and the Corporations Regulations 2001.
The Financial Report comprises the:
/ Consolidated balance sheet as at 31 December 2017;
/ Consolidated statement of comprehensive income, consolidated statement of changes
in equity, and consolidated statement of cash flows for the year then ended;
/ Notes including summary of significant accounting policies; and
/ Directors’ Declaration.
The Consolidated Entity consists of OZ Minerals Limited (the Company) and the entities
it controlled at the year end and from time to time during the financial year.
Basis for opinion
We conducted our audit in accordance with Australian Auditing Standards. We believe
that the audit evidence we have obtained is sufficient and appropriate to provide a basis
for our opinion.
Our responsibilities under those standards are further described in the Auditor’s
responsibilities for the audit of the Financial Report section of our report.
We are independent of the Consolidated Entity in accordance with the Corporations Act
2001 and the relevant ethical requirements of the Accounting Professional and Ethical
Standards Board’s APES 110 Code of Ethics for Professional Accountants (the Code).
We have fulfilled our other ethical responsibilities in accordance with the Code.
Key audit matters
The Key Audit Matters we identified are:
/ Carrying value of Prominent Hill Property, Plant and Equipment (PP&E)
/ Valuation of Low Grade Gold Ore Stockpiles
Key Audit Matters are those matters that, in our professional judgment, were of most
significance in our audit of the Financial Report of the current period.
These matters were addressed in the context of our audit of the Financial Report as a
whole, and in forming our opinion thereon, and we do not provide a separate opinion
on these matters.

Carrying value of Prominent Hill PP&E (contained within total PP&E $1,175.8m)
Refer to Note 7 to the Financial Report
The key audit matter
The carrying value of Prominent Hill PP&E is a key audit matter due to the audit effort
involved in assessing the Group’s determination that no impairment indicators existed
in relation to the Prominent Hill PP&E.
Important factors included:
/ The significance of this determination and its effect on the extent and granularity of
the Group’s assessment of the carrying value. The presence of impairment indicators
would necessitate a detailed analysis by the Group of the recoverable amount of
Prominent Hill PP&E. In light of the quantum of the Prominent Hill PP&E (being 25%
of total assets), the presence of impairment indicators would impact the scope of
our work.
/ The historic sensitivity of the Group’s modelling to external and internal conditions.
This heightens the likelihood of small changes in conditions from previous years
leading to indicators of impairment.
In assessing the presence of impairment indicators, we particularly focused on the
external and internal conditions listed below. We assessed each condition against the
equivalent in the previous impairment assessment and the Group’s mine plan (where
applicable), for inconsistent or negative trends, which may indicate impairment of the
carrying value.
/ Commodity price and foreign exchange rate forecasts.
/ Prominent Hill operational plans and budgets, in particular:
> Metal production levels planned: these are dependent on extraction of ore from
the mine, estimated grades of metal in the ore body, and ability to recover metal
contained in the ore extracted.
> Capital expenditure and operating costs: such as underground mining costs,
processing costs, freight and TCRC (treatment costs and refining charges).
/ Discount rate based on market evidence of comparable organisations within the
same industry.
/ The valuation multiples used by the Group to ascribe value to the ore bodies
known to exist at Prominent Hill but have not been included in the Group’s primary
impairment indicator assessment.
We involved senior audit team members, including KPMG valuations specialists,
with experience in the industry for this key audit matter.
How the matter was addressed in our audit
Involving our valuations specialists, our procedures included:
/ We tested the controls for the Group’s compilation of their operational plans and
budgets for Prominent Hill PP&E into their primary impairment indicator assessment,
including board authorisation of key inputs. In assessing the due process involved
into its compilation, we critically evaluated the following key forecast inputs for
accuracy:
> Metal production levels against historical production levels and the capacity to
achieve forecast production;
> Capital expenditure against historical capital expenditure and for consistency
with the planned activities that may require capital; and
> Operating costs, against historical amounts and for consistency with the mine
plan.
/ In assessing for negative trends in the forecast cash flows of Prominent Hill PP&E, we
challenged the Group’s key internal inputs from above against those in the previous
impairment assessment. Specific to Prominent Hill’s future production levels we used
our knowledge of previous production levels and evaluated against:
> Board approved current business model.
> The Mineral Resources and Ore Reserves Statements prepared by the Group in
accordance with Joint Ore Reserves Committee (JORC) requirements for ore to be
mined and processed. These requirements govern evaluation and reporting of the
existence of mineral resources.
> Findings from external specialists, engaged by the Group in prior years that
remain relevant, to assess the accuracy of JORC Resource and Reserve estimates
for information which may indicate that estimates of ore to be mined and
processed are not achievable.
/ We assessed the relevant discount rates sourced from comparable market rates for
negative trends against the previous impairment assessment;
/ We compared forecast commodity prices and foreign exchange rates applicable to
the Group’s businesses, via published analyst and broker data, for negative trends
against the previous impairment assessment;
/ In assessing for negative trends in the value ascribed to the ore bodies known to
exist at Prominent Hill but have not been included in the impairment indicator
assessment calculation, we compared the valuation multiples used to market data
for comparable transactions and prior period valuation multiples.

Valuation of Low Grade Gold Ore Stockpiles ($163.4 million)
Refer to Note 5 to the Financial Report
The key audit matter
Significant judgment is required to be exercised by the Group in their assessment of
the value of low grade gold ore which will be combined with copper ore to be mined
in the future to produce concentrate. The valuation of low grade gold ore stockpiles
is a key audit matter because significant judgment is required by us in evaluating the
Group’s assessment of the value. The Group’s assessment is based on a model which
estimates future revenue expected to be derived from low grade gold ore contained
in existing ore stockpiles, less selling costs and further processing costs to convert ore
into concentrate. We particularly focus on those judgments listed below which impact
the valuation model:
How the matter was addressed in our audit
Our procedures included:
/ We tested the controls relevant to:
> the Group’s valuation of low grade gold ore stockpiles, including board
authorisation of key inputs to the assessment such as commodity prices, foreign
exchange rates, and processing costs; and,
> the Group’s process for recording and monitoring volumes and grades of
stockpiled low grade gold ore such as the use of quantity surveyors and
management review and approval of grades.
/ Future metal production levels which are dependent on the volume and grade of
/ We assessed the methodology applied by the Group in determining the value of
existing low grade gold ore stockpiles.
/ Future processing costs of low grade gold ore, and related selling costs.
/ Future commodity prices and foreign exchange rates expected to prevail when the
concentrate containing gold from existing low grade gold ore stockpiles is processed
and sold.
/ The timing of production which depends on the available capacity of the mill.
In assessing this key audit matter, we used team members who understand the
Group’s business, industry and the relevant economic environment.
low grade gold ore stockpiles against the requirements of Accounting Standards for
determining the net realisable value of inventories which are yet to be converted into
finished goods.
/ We compared the results of quantity surveyors to volume of low grade gold ore
stockpiles.
/ We compared grades of stockpiled low grade gold ore to stockpiled low grade
gold ore in previous periods, and against grades reported in the JORC Ore Reserves
Statement.
/ We evaluated the Group’s key assumptions used to determine the value of low grade
gold ore stockpiles by:
> comparing forecast processing costs of low grade gold ore against historical
actual processing costs to assess forecast processing cost assumptions;
> assessing forecast selling costs by comparing to trends from evaluation of
existing customer sales contracts;
> assessing commodity prices and foreign exchange rates applied by the Group
against published analyst and broker data about commodity prices and foreign
exchange rates expected to prevail in the future; and,
> checking that low grade gold ore was only forecast to be processed when there
was capacity in the mill.

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 this
Financial Report.
A further description of our responsibilities
for the Audit of the Financial Report is

Standards Board website at: http://www.
