ASX/Media Release 14 September 2015

DOOLGUNNA PROJECT - MONTY DRILLING UPDATE

Near-surface massive sulphides intersected in two step-out RC holes along strike from TLRC0004

Sandfire Resources NL (ASX: SFR; "Sandfire") is pleased to provide an update on ongoing exploration drilling being undertaken at the Monty copper-gold discovery located 10km east of the DeGrussa Copper-Gold Mine on the Springfield Project, part of its farm-in with Talisman Mining Limited (ASX: TLM; "Talisman") (see Figures 1 and 2).

Two Reverse Circulation (RC) step-out holes designed to test potential extensions to the previously reported shallow intercept in TLRC0004 (18.0m grading 5.7% Cu and 2.4g/t Au from 107.0m) have intersected mineralisation along strike on either side of TLRC0004:

Step-out hole TLRC0008 intersected two zones of massive sulphide mineralisation approximately 40 metres along strike to the south-west of TLRC0004:

• 2.0 metres of massive sulphides (lightly weathered) from 90m to 92m down-hole;

(true width not known at this time, top of intercept is approximately 80 metres vertically below surface);

and

• 11.0 metres of massive sulphides from 111m to 122m down-hole (1.0m of siltstone from 114m)

(true width not known at this time, top of intercept is approximately 99 metres vertically below surface)

Step-out hole TLRC0009 also intersected two zones of massive sulphide mineralisation approximately 40 metres along strike to the north-east of TLRC0004:

• 8.0 metres of massive sulphides from 133m to 141m down-hole;

(true width not known at this time, top of intercept is approximately 118 metres vertically below surface); and

• 1.0 metre of massive sulphides from 158m to 159m down-hole

(true width not known at this time, top of intercept is approximately 141 metres vertically below surface)

RC samples from the holes will be dispatched for assaying. Updated collar locations are shown in Figure 2. Further, RC hole TLRC0006, located 45 metres along strike to the south-west of TLRC0008, has drilled

through a sequence of siltstones and dolerites to a depth of 187m down-hole. From 187m to the end of hole

(318m), TLRC0006 drilled through a strongly sheared sequence which included dolerites, siltstones and basalt. This is consistent with the recently interpreted faulting shown Figure 2.

Elsewhere, Diamond drill holes TLDD0015 and TLDD0016 have been completed approximately 166 metres up-dip of TLDD0010 and 134 metres up-dip of TLDD0009 respectively. These holes intersected the host horizon above the projected plunge of the previously intersected massive sulphides in accordance with the updated interpretation outlined in the Announcement of 8 September 2015 (and shown again in the Vertical Long Projection in Figure 3).

Both holes, which were collared prior to this advance in the Company's understanding of the orientation of the mineralisation at Monty, intersected the prospective sedimentary horizon with TLDD0016 intersecting exhalative haematitic alteration and trace sulphides from 167m to 170m down-hole.

Drilling is continuing at Monty with additional Diamond holes underway and planned to test for extensions of the mineralisation both up and down-plunge, up- and down-dip and along strike. Drilling is being supported by down-hole EM surveys.

Sandfire is earning a 70% interest in the Talisman Mining's Doolgunna Project, which forms part of its Greater Doolgunna Project comprising a 1,700 square kilometre package of contiguous tenements surrounding the DeGrussa Copper Mine.

Competent Person's Statement - Exploration Results

The information in this report that relates to Exploration Results is based on information compiled by Mr. Shannan Bamforth who is a Member of The Australasian Institute of Mining and Metallurgy. Mr. Bamforth is a permanent employee of Sandfire Resources and has sufficient experience that is relevant to the style of mineralisation and type of deposit under consideration and to the activity which he is undertaking to qualify as Competent Person as defined in the 2012 Edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves. Mr Bamforth consents to the inclusion in the report of the matters based on his information in the form and context in which it appears.

Exploration and Resource Targets

Any discussion in relation to the potential quantity and grade of Exploration Targets is only conceptual in nature. While Sandfire is confident that it will report additional JORC compliant resources for the DeGrussa Project, there has been insufficient exploration to define mineral resources in addition to the current JORC compliant Mineral Resource inventory and it is uncertain if further exploration will result in the determination of additional JORC compliant Mineral Resources.

Forward-Looking Statements

Certain statements made during or in connection with this statement contain or comprise certain forward-looking statements regarding Sandfire's Mineral Resources and Reserves, exploration operations, project development operations, production rates, life of mine, projected cash flow, capital expenditure, operating costs and other economic performance and financial condition as well as general market outlook. Although Sandfire believes that the expectations reflected in such forward-looking statements are reasonable, such expectations are only predictions and are subject to inherent risks and uncertainties which could cause actual values, results, performance or achievements to differ materially from those expressed, implied or projected in any forward looking statements and no assurance can be given that such expectations will prove to have been correct. Accordingly, results could differ materially from those set out in the forward-looking statements as a result of, among other factors, changes in economic and market conditions, delays or changes in project development, success of business and operating initiatives, changes in the regulatory environment and other government actions, fluctuations in metals prices and exchange rates and business and operational risk management. Except for statutory liability which cannot be excluded, each of Sandfire, its officers, employees and advisors expressly disclaim any responsibility for the accuracy or completeness of the material contained in this statement and excludes all liability whatsoever (including in negligence) for any loss or damage which may be suffered by any person as a consequence of any information in this statement or any error or omission. Sandfire undertakes no obligation to update publicly or release any revisions to these forward-looking statements to reflect events or circumstances after today's date or to reflect the occurrence of unanticipated events other than required by the Corporations Act and ASX Listing Rules. Accordingly you should not place undue reliance on any forward looking statement.

JORC Compliance Statement

A summary of the information used in this release is as follows.
The DeGrussa VHMS (volcanic-hosted massive sulphide) copper-gold deposit is located 900 kilometres north of Perth and 150 kilometres north of Meekatharra in the Peak Hill Mineral Field. The system is hosted within a sequence of metasediments and mafic intrusions situated in the Bryah Basin that have been metamorphosed and structurally disrupted.
The sulphide mineralisation consists of massive sulphide and semi-massive sulphide mineralisation. Primary sulphide minerals present are pyrite, chalcopyrite, pyrrhotite and sphalerite, together with magnetite. The sulphide mineralisation is interpreted to be derived from volcanic activity. The deposit shares characteristics with numerous VHMS deposits worldwide.
Sandfire Resources are currently exploring the defined prospective sequence in its 100% held tenements and within the Talisman Mining earn in and joint Venture agreement.

Section 1: Sampling Techniques and Data

Criteria

JORC Code Explanation

Commentary

Sampling

techniques

• Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling.

• Sampling method include half-core sampling of NQ2 core Diamond drilling (DD).

• RC samples are collected by a cone splitter for single metre samples or a sampling spear for first pass composite samples using a face sampling hammer with a nominal 140mm hole.

Sampling

techniques

• Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used.

• Sampling is guided by Sandfire protocols as per industry standard.

Sampling

techniques

• Aspects of the determination of mineralisation that are Material to the Public Report.

• In cases where 'industry standard' work has been done this would be relatively simple (eg 'reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay'). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information.

• DD Sample size reduction is through a Jaques jaw crusher to -10mm with a second stage reduction via Boyd crusher to -4mm. Representative subsamples are split and pulverised through LM5.

• RC sample are crushed to -4mm through a Boyd crusher and representative subsamples pulverised via LM5.

• Pulverising is to nominal 90% passing -75µm and checked using wet sieving technique.

• Samples are assayed using Mixed 4 Acid Digest (MAD) 0.3g charge and

MAD Hotbox 0.15g charge methods with ICPOES or ICPMS.

• Fire Assay is completed by firing 40g portion of the sample with ICPMS finish.

Drilling techniques

• Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg core diameter, triple or standard tube, depth of Diamond tails, face- sampling bit or other type, whether core is oriented and if so, by what method, etc).

• DD is completed using NQ2 size coring equipment.

• RC drilling is with sampling hammer of nominal 140mm hole.

• All drill collars are surveyed using RTK GPS with downhole surveying.

• All core where possible is oriented using a Reflex ACT II RD orientation tool.

• Downhole surveying is undertaken using a gyroscopic survey instrument.

Drill sample

recovery

• Method of recording and assessing core and chip sample recoveries and results assessed.

Diamond core recovery is logged and captured into the database. Core recoveries are measured by drillers for every drill run. The core length recovered is physically measured for each run and recorded and used to calculate the core recovery as a perecentage core recovered.

Criteria

JORC Code Explanation

Commentary

• Measures taken to maximise sample recovery and ensure representative nature of the samples.

• Appropriate measures are taken to maximise sample recovery and ensure the representative nature of the samples. This includes Diamond core being reconstructed into continuous intervals on angle iron racks for orientation, metre marking and reconciled against core block markers.

• RC sampling is good with almost no wet sampling in the project area.

• Samples are routinely weighed and captured into the central secured database.

• Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material.

• No sample recovery issues have impacted on potential sample bias.

Logging

• Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies.

• Geological logging is completed for all holes and representative across the orebody. The lithology, alteration and structural characteristics of core are logged directly to a digital format following procedures and using Sandfire NL geologic codes. Data is imported into Sandfire NL's central database after validation in LogChief™.

Logging

• Whether logging is qualitative or quantitative in nature. Core

(or costean, channel, etc) photography.

• Logging is both qualitative and quantitative depending on field being logged.

• All drillholes are fully logged.

Sub-sampling

techniques and sample preparation

• If core, whether cut or sawn and whether quarter, half or all core taken.

• Core orientation are completed where possible and all are marked prior to sampling. Half core samples are produced using Almonte Core Saw. Samples are weighed and recorded.

Sub-sampling

techniques and sample preparation

• If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry.

RC samples are split using a cone or riffle splitter. A majority of RC samples are dry. On occasions that wet samples are encountered they are dried prior to splitting with a riffle splitter.

Sub-sampling

techniques and sample preparation

• For all sample types, the nature, quality and appropriateness of the sample preparation technique.

• All samples are sorted, dried at 80° for up to 24 hours and weighed. DD samples are then crushed through Jaques crusher to nominal -10mm. A second stage crushing is through Boyd crusher to nominal -4mm. All RC samples are only Boyd crushed to -4mm.

• Sample splits are weighed at a frequency of 1:20 and entered into the job results file. Pulverising is completed using LM5 mill to 90% passing 75%µm using wet sieving technique.

Criteria

JORC Code Explanation

Commentary

• Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples.

• 1:20 grind quality checks are completed for 90% passing 75%µm criteria to ensure representativeness of sub-samples.

• Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling.

• Sampling is carried out in accordance with Sandfire protocols as per industry best practice.

• Samples are assayed using Mixed 4 Acid Digest (MAD) 0.3g charge and MAD Hotbox 0.15g charge methods with ICPOES or ICPMS. The samples are digested and refluxed with a mixture of acids including Hydrofluoric, Nitric, Hydrochloric and Perchloric acids and conducted for multi elements including Cu, Pb, Zn, Ag, As, Fe, S, Sb, Bi, Mo, Re, Mn, Co, Cd, Cr, Ni, Se, Te, Ti, Zr, V, Sn, W and Ba. The MAD Hotbox method is an extended digest method that approaches a total digest for many elements however some refractory minerals are not completely attacked. The elements S, Cu, Zn, Co, Fe, Ca, Mg, Mn, Ni, Cr, Ti, K, Na, V are determined by ICPOES, and Ag, Pb, As, Sb, Bi, Cd, Se, Te, Mo, Re, Zr, Ba, Sn, W are determined by ICPMS. Samples are analysed for Au, Pd and Pt by firing a 40g of sample with ICP AES/MS finish. Lower sample weights are employed where samples have very high S contents. This is a classical FA process and results in total separation of Au, Pt and Pd in the samples.

• The analytical methods are considered appropriate for this mineralisation styles.

• For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc.

Drill hole

Information

A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes:

o easting and northing of the drill hole collar

o elevation or RL (Reduced Level - elevation above sea level in metres)

of the drill hole collar

o dip and azimuth of the hole

o down hole length and interception depth

o hole length.

If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case.

• Refer to Appendix 1 of this accompanying document.

Data

aggregation methods

• In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated.

• Significant intersections are based on greater than 0.5% Cu and may include up to a maximum of 3.0m of internal dilution, with a minimum composite grade of

1.0% Cu.

• Cu grades used for calculating significant intersections are uncut.

Data

aggregation methods

• Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail.

• Minimum and maximum DD sample intervals used for intersection calculation are 0.3m and 1.2m respectively subject to location of geological boundaries.

widths and intercept lengths

• These relationships are particularly important in the reporting of Exploration Results.

• Downhole intercepts of mineralisation reported in this release are from a drillhole orientated perpendicular to a modelled EM plate. The drillhole may not necessarily be perpendicular to the mineralised zone. All widths reported are downhole intervals.

Relationship

between mineralisation

widths and intercept lengths

• If the geometry of the mineralisation with respect to the drill- hole angle is known, its nature should be reported.

• The geometry of the mineralisation, relative to the drillhole, is unknown at this stage.

• If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg 'down hole length, true width not known').

• All intersections reported in this release are downhole intervals. True widths are not known.

Diagrams

• Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views.

• Appropriate maps are included within the body of the accompanying document.

Balanced

reporting

• Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results.

• The accompanying document is considered to represent a balanced report.

Other

substantive exploration data

• Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples - size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances.

• Other exploration data collected is not considered as material to this document at this stage. Further data collection will be reviewed and reported when considered material.

Further work

• The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling).

• Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive.

• Step-out drilling for along-strike and down-dip extensions of mineralisation continue on 160m x 80m x 80m grid pattern subject to geological and geophysical interpretation.
