CARRAPATEENA PRE-FEASIBILITY STUDY BRETT TRIFFETT – MANAGER TECHNICAL SERVICES 5 DECEMBER 2014

There are very few projects like Carrapateena which offer the potential

of multi-decade production at low operating costs, with the

demonstrated potential for further discoveries nearby, located relatively

close to all necessary infrastructure and in one of the best and safest

mining jurisdictions in the world.

DRILL HOLE INFORMATION – JORC TABLE 1

Section 1 Sampling Techniques and Data

Criteria Comments

Sampling

techniques

All basement samples consist of diamond drill core (NQ2 and HQ) cut with an automatic core saw and sampled as half core, except

for field duplicates, where quarter core was sampled. The method of sampling is considered to be of an acceptable quality for the

reporting of Exploration Results.

Predominantly 1m samples were obtained, but lengths range from 0.5m to 1.5m where adjusted to geological or major alteration

boundaries. All available basement drill core was sampled.

Entire samples were crushed then pulverised to a nominal 90% passing 75 microns. The resulting pulps were analysed using a

variety of methods which included multi acid digest with ICP-OES determination for Cu, and fire assay (40g charge) with AAS finish

for Au. Sub-sampling, sample preparation, assay methods and assay quality are discussed in the criterion Sub-sampling techniques

and sample preparation below.

Drilling techniques Drill holes were diamond cored from surface using a combination of PQ, HQ and NQ2 core sizes. Holes were inclined and core was

oriented using an ACT core orientation tool.

Drill sample

recovery

Length-based core recovery was measured from reassembled core for every drill run. The data were recorded in a SQL Server

database via a GBIS front end. Average core recovery was high with more than 99 percent recovered through the reported

intersections.

The style of mineralisation and drilling methods employed lead to very high sample recovery, so no further effort was considered

necessary to increase core recovery.

Scatterplots of grade and core recovery do not suggest any relationship. The very high core recovery means that any effect of such

losses would be negligible if such a relationship were to exist.

Logging All core samples were geologically logged by geologists and are considered to have been logged in appropriate detail to support

Mineral Resource estimation, mining studies and metallurgical studies. Detailed geotechnical logging was not carried out for the

reported drill holes, however RQD and geological structural data were collected for all core drilled.

Core logs were qualitative and quantitative in nature. Lithology and alteration were logged qualitatively; mineralisation and

structure were logged quantitatively. Core was photographed both dry and wet after metre marking and orientation.

All recovered core (100 percent) from the relevant intersections was geologically logged.

JORC 2012 TABLE 1

OZ Minerals | 16

Section 1 Sampling Techniques and Data

Criteria Comments

Sub-sampling

techniques and

sample

preparation

All sampled core was cut with an automatic core saw in a consistent way that preserved the bottom of hole reference line, where

present. Half core was used for normal sampling and quarter core for field duplicates. Samples were mostly 1m in length, but also

ranged from 0.5m to 1.5m if adjusted to geological or major alteration boundaries.

Only core samples were used in basement.

Sample preparation included drying, crushing, and pulverising in full to a nominal 90% passing 75 microns. This is considered

industry standard for this style of mineralisation.

Controlled copies of SOPs (Standard Operating Procedures) and sign-offs exist for all sampling steps, and all staff were adequately

trained in these. Checks were made by geologists on sampling prior to loading data into the database.

Sample representativity was monitored by taking field duplicates, lab coarse crush, and pulp duplicates every 50 samples. Sizing

data was collected for one in every 20 pulverised samples by the laboratory analysing the samples. Analysis of these results

indicates that the sampling is representative.

Analysis of duplicate data from a variety of scales, from quarter core to crushed core to pulp duplicates, indicates the sample sizes

are appropriate to the grain size of the material being sampled.

Quality of assay

data and

laboratory tests

All samples were assayed at Bureau Veritas Adelaide Laboratory (Amdel). Copper grades were determined using a multi-acid digest

with ICP-OES finish. Gold grades were determined by 40g fire assay with AAS finish.

Review of QAQC results confirms that the quality of the data is acceptable.

Geophysical measurements of magnetic susceptibility and radioactivity were taken on drill core but these data have not been used

to determine any element concentrations.

Assay data quality was monitored through submission of certified standards and blanks every 25 samples, quarter core field

duplicates and lab coarse crush and pulp duplicates every 50 samples. Analysis of results from these samples showed that levels of

bias, precision and contamination are within limits that are considered acceptable.

JORC 2012 TABLE 1

OZ Minerals | 17

Section 1 Sampling Techniques and Data

Criteria Comments

Verification of

sampling and

assaying

Documented verification of significant intervals by independent personnel has not been done, however the intersections have been

verified by alternative personnel within OZ Minerals and the tenor of Cu is visually predictable.

No twin holes have been drilled because the focus to date has been on finding high grade mineralisation.

Primary data is stored both in its source electronic form, and, where applicable, on paper. Assay data is retained in both the original

certificate (.pdf) form, where available, and the text files received from the laboratory. Core logging was recorded directly into the

database using Toughbooks. Core length measurements for recovery were made on paper prior to entry into the database.

Different user profiles and security settings exist to minimise the possibility of inadvertent modification of data. Assay data were

reviewed visually to confirm that reported values are reasonable.

Where assay results are below detection limit, a value of half the detection limit has been used. No other adjustments were made to

assay data.

Location of data

points

All collar locations were determined by DGPS, or GPS for easting and northing, projected onto a digital terrain model (DTM) to

determine elevation.

All drill holes had magnetic down hole surveys taken at nominal 30m intervals using digital Reflex EZ-Trac equipment. Completed

holes were gyro surveyed using a conventional Reflex Gyro tool. The collar reference azimuth for most holes was calculated using a

"best-fit" with EZ-Trac (magnetic) surveys in non-magnetic ground in the cover sequence. To minimise the effect of drift of azimuth

measurements with the conventional gyro, an average of multiple runs was normally used, typically four runs. The difference in

interpreted volume of mineralisation due to drill hole position uncertainty is considered to be immaterial for the purpose of

reporting Exploration Results or estimating Mineral Resources.

The grid is MGA94 zone 53 south. Local elevations have been used, where 5000mRL is equal to Australian Height Datum.

A DTM was flown by OZ Minerals in April 2012. The accuracy of the 2012 DTM is considered to be acceptable for the determination

of collar elevation for the reported Exploration Results.

Section 1 Sampling Techniques and Data

Criteria Comments

Data spacing and

distribution

Drill holes at Fremantle Doctor were drilled in a variety of directions and the spacing between holes is not uniform. Drill hole

locations are shown in Slide 21 in the accompanying presentation.

At Fremantle Doctor, holes have been drilled in different directions so the hole spacing varies widely depending on the location.

The closest distance between any two neighbouring significant intersections reported to date varies from 23m (between

DD13FDR005 and DD14FDR005W1) to approximately 290m (between DD14FDR008 and DD14FDR009). It should be noted that

these are the closest distances, the holes generally diverge with depth and the mean distances between significant intervals are

larger than this.

No new or updated Mineral Resource or Ore Reserve estimate has been reported in this release.

No physical compositing of samples has occurred.

Orientation of data

in relation to

geological

structure

At Fremantle Doctor, the current, preliminary interpretation of the mineralisation is a sub-vertical body trending to the NNE/SSW

dipping steeply to the WNW. The reported drilling occurs in an East, South-East and North orientation and intersects the

interpreted structure of copper mineralisation obliquely.

The orientations of drill holes are sufficiently varied that drilling orientation is not considered to have introduced a significant

sampling bias.

Sample security Samples were sent via road transport from Carrapateena Exploration Site to the laboratory in Adelaide. Despatches listing samples

were sent electronically to the laboratory. Any discrepancy between listed and received samples was communicated back to site

staff for resolution.

Audits or reviews An external audit of Bureau Veritas Adelaide laboratory was undertaken by ioGlobal in October 2012. OZ Minerals geologists

inspected Bureau Veritas Adelaide laboratory during April 2014. Minor issues were noted on both the audit and inspection but were

not considered to be material overall.

Drilling and core processing at Fremantle Doctor is conducted using the same facilities and protocols as for the Carrapateena

deposit. AMC Consultants Pty Ltd undertook a review of the data collection and sampling procedures during an audit of the

Carrapateena Mineral Resource estimate between 30 September and 3 October 2013. AMC formed the view that the data collection

procedures were industry standard practice, with the exception of the monitoring of the quality control samples, which did not

appear to be being undertaken on a batch by batch and continuous basis. Since AMC’s audit, quality control data has been

reviewed more frequently, and systematic monitoring of quality data occurs prior to the release of Exploration Results in any case.

Mineral tenement and land

tenure status

The Fremantle Doctor prospect is located in South Australia in Exploration Licence 4903 which is held by OZ Minerals

Carrapateena Pty Ltd (34%) and OZM Carrapateena Pty Ltd (66%), both wholly owned subsidiaries of OZ Minerals

Limited.

The tenement sits within the Kokatha Uwankara Native Title Claim.

EL4903 is currently in good standing. No known impediments exist to obtaining a licence to operate in the area.

Exploration done by other

parties

In 2007 under a joint venture between RMG Services Pty and Teck Cominco Australia Pty Ltd, two holes were drilled on

the northern margin of the Fremantle Doctor prospect (FD001 and FD002). They intersected altered granite-hematite

breccias with patchy chalcopyrite mineralisation and altered granite with no observed mineralisation respectively.

Geology The Fremantle Doctor prospect is located within the Olympic copper gold (Cu-Au) Province on the eastern edge of the

Gawler Craton. Mineralisation is hosted within Donington Suite granite and unconformably overlain by approximately

530m to 570m of Neoproterozoic sediments. Mineralisation and alteration is in the form of that seen at other large

South Australian iron oxide copper gold (IOCG) deposits including Prominent Hill, Carrapateena and Olympic Dam.

Drill hole Information Refer to Table on page 14.

All information material to the understanding of the Exploration Results has been included. Drill hole information for

holes shown on the plan and section slides which are not included in Table on page 14 have been previously reported.

Data

Relationship

between

mineralisation

widths and

intercept lengths

At Fremantle Doctor, preliminary modelling indicates the mineralisation envelope is a massive body dipping steeply to

the west-northwest with localised high grade zones having uncertain orientations. The interpreted envelope starts

approximately 530m below the surface. Envelope boundaries are unknown at this stage as they are not constrained by

many drill holes.

The current modelling for the Fremantle Doctor prospect is still preliminary, and the angle at which mineralisation has

been intersected is not known.

Mineralisation at Fremantle Doctor has been reported as down hole lengths as the true width is not known.

Diagrams Refer to Slide 10, 11 and 21 in the accompanying presentation.

Balanced

reporting

All significant Exploration Results at Fremantle Doctor are reported. Drill holes which have been omitted from slide 10

to 11 have been previously reported. The drill hole information for these holes is included on Slide 21.

Other

exploration data

There is no other material exploration data at this time.

Further work Further drilling is currently ongoing at the Fremantle Doctor prospect to increase the confidence in location of
