DISCLAIMER & CP STATEMENT Certain statements contained in this presentation, including information as to the future financial or operating performance of Sirius Resources and its projects, are forward-looking statements. Such forward-looking statements: are necessarily based upon a number of estimates and assumptions that, whilst considered reasonable by Sirius Resources, are inherently subject to significant technical, business, economic, competitive, political and social uncertainties and contingencies; involve known and unknown risks and uncertainties that could cause actual events or results to differ materially from estimated or anticipated events or results reflected in such forward-looking statements; and may include, among other things, statements regarding targets, estimates and assumptions in respect of metal production and prices, operating costs and results, capital expenditures, ore reserves and mineral resources and anticipated grades and recovery rates, and are or may be based on assumptions and estimates related to future technical, economic, market, political, social and other conditions. Sirius Resources disclaims any intent or obligation to update publicly any forward-looking statements, whether as a result of new information, future events or results or otherwise. The words “believe”, “expect”, “anticipate”, “indicate”, “contemplate”, “target”, “plan”, “intends”, “continue”, “budget”, “estimate”, “may”, “will”, “schedule” and other similar expressions identify forward-looking statements. All forward-looking statements made in this presentation are qualified by the foregoing cautionary statements. Investors are cautioned that forward-looking statements are not guarantees of future performance and accordingly investors are cautioned not to put undue reliance on forward-looking statements due to the inherent uncertainty therein. The information in this report that relates to Exploration Results is based on information compiled by Mark Bennett and Andy Thompson who are employees of the company. Dr Bennett is a member of the Australasian Institute of Mining and Metallurgy, a fellow of the Australian Institute of Geologists and a fellow of the Geological Society of London. Mr Thompson is a member of the Australasian Institute of Mining and Metallurgy. Dr Bennett and Mr Thompson have sufficient experience of relevance to the styles of mineralisation and the types of deposits under consideration, and to the activities undertaken, to qualify as Competent Persons as defined in the 2012 Edition of the Joint Ore Reserves Committee (JORC) Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves. Dr Bennett and Mr Thompson consent to the inclusion in this report of the matters based on information in the form and context in which it appears. Exploration results are based on standard industry practices, including sampling, assay methods, and appropriate quality assurance quality control (QAQC) measures. Reverse circulation (RC), aircore (AC) and rotary air blast (RAB) drilling samples are collected as composite samples of 4 or 2 metres and as 1 metre splits (stated in results). Mineralised intersections derived from composite samples are subsequently re-split to 1 metre samples to better define grade distribution. Core samples are taken as half NQ core or quarter HQ core and sampled to geological boundaries where appropriate. The quality of RC drilling samples is optimised by the use of riffle and/or cone splitters, dust collectors, logging of various criteria designed to record sample size, recovery and contamination, and use of field duplicates to measure sample representivity. For soil samples, PGM and gold assays are based on an aqua regia digest with Inductively Coupled Plasma (ICP) finish and base metal assays may be based on aqua regia or four acid digest with inductively coupled plasma optical emission spectrometry (ICPOES) or atomic absorption spectrometry (AAS) finish. In the case of reconnaissance RAB, AC, RC or rock chip samples, PGM and gold assays are based on lead or nickel sulphide collection fire assay digests with an ICP finish, base metal assays are based on a four acid digest and inductively coupled plasma optical emission spectrometry (ICPOES) and atomic absorption spectrometry (AAS) finish, and where appropriate, oxide metal elements such as Fe, Ti and Cr are based on a lithium borate fusion digest and X-ray fluorescence (XRF) finish. In the case of strongly mineralised samples, base metal assays are based on a special high precision four acid digest (a four acid digest using a larger volume of material) and an AAS finish using a dedicated calibration considered more accurate for higher concentrations. Sample preparation and analysis is undertaken at Minanalytical, Genalysis Intertek and Ultratrace laboratories in Perth, Western Australia. The quality of analytical results is monitored by the use of internal laboratory procedures and standards together with certified standards, duplicates and blanks and statistical analysis where appropriate to ensure that results are representative and within acceptable ranges of accuracy and precision. Where quoted, nickel-copper intersections are based on a minimum threshold grade of 0.5% Ni and/or Cu, and gold intersections are based on a minimum gold threshold grade of 0.1g/t Au unless otherwise stated. Intersections are length and density weighted where appropriate as per standard industry practice. All sample and drill hole co-ordinates are based on the GDA/MGA grid and datum unless otherwise stated. Exploration results obtained by other companies and quoted by Sirius have not necessarily been obtained using the same methods or subjected to the same QAQC protocols. These results may not have been independently verified because original samples and/or data may no longer be available. The information in this report that relates to Mineral Resource Estimation is based on information compiled by Mr Mark Drabble, Principal Consultant Geologist – Optiro Pty Ltd and Mr Andrew Thompson, a full time employee and General Manager Resources and Geology of Sirius Resources NL. Mr Drabble and Mr Thompson are members of the Australasian Institute of Mining and Metallurgy and have sufficient experience which is relevant to the style of mineralisation and type of deposit under consideration to qualify as a Competent Person as defined in the 2012 Edition of the “Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves” (JORC Code). Mr Drabble and Mr Thompson consent to the inclusion in this report of the matters based on their information in the form and context in which they appear.

MINING & PROCESSING STUDIES

Preliminary geotechnical and mining studies indicate Nova

will be a very low cost nickel mine:

Crystalline competent hostrock with good geotechnical

characteristics (unlike most WA nickel mines)

Amenable to bulk mining methods: <90 metre high stopes,

sub-level open stoping and long hole stoping at margins

Preliminary metallurgical testwork indicates Nova will

produce a high value, sought after product:

Low MgO concentrate (unlike most WA nickel mines)

No arsenic, Ni in pentlandite, Cu in chalcopyrite

Very coarse grain size – potential rapid, low energy

crush/grind

High recovery of Ni & Cu in initial flotation testwork

Potential for separate Ni (Co) & Cu (Ag) concentrates

THE EYE – A CLUSTER ?

The Eye is a 3km long prospective structure

Nova is located on the western rim of the Eye

Other prospects along strike (conductor 5, Tethys)

on western rim

Gravity is designed to see dense rocks below the

effective depth penetration range of EM

Nova has a gravity anomaly

There is a MAJOR gravity anomaly northeast of

Nova and Bollinger that is as yet hardly tested by

drilling

This could be the central intrusive complex

sourcing what we have seen so far

A NEW DISTRICT ?

Targeted as a deformed intrusion, sill

complex, dome or layered igneous

complex – all prospective for nickel

The Yardilla EM anomaly is 20km west of Nova

The Yardilla EM anomaly is as strong as Nova but twice as long

A NEW PROVINCE ?

Unexplored and/or ineffectively explored

+100 km strike/2,000 square km held by Sirius in the belt

Ground EM has now extended to Yardilla

70% interest through a JV with Mark Creasy (30%) who is free carried to completion of BFS

Majority of this new nickel–copper province held by Sirius or its major shareholder and JV partner, Mark Creasy

Prospective for Proterozoic circum-cratonic intrusive-associated magmatic Ni-Cu deposits like those in Canada

Only 30km to the sealed Eyre Highway and then to export port of Esperance

A SIMPLE, BOLD, EFFECTIVE VISION

• To make Nova/Bollinger a producing nickel mine with minimal dilution to shareholders and maximum leverage to metal prices

• To make Nova/Bollinger Australia’s lowest cost/highest margin nickel mine

• To grow Sirius into the pre-eminent nickel-copper-cobalt producer in Australia

• To find more deposits nearby and rapidly grow the potential future resource base, production profile and mine life

• To also discover a major gold deposit at Polar Bear and/or Fraser Range
