Monty Resource Definition Drilling Since the last Monty exploration update (see Talisman ASX Announcement – 20 January 2016 Monty Exploration Update), Talisman understands drilling has focused on resource definition within the Upper and Lower Zones of Monty and that this drilling program is essentially complete. The information generated by this resource definition drilling will support the maiden Mineral Resource estimate for Monty, which Talisman understands to be on track to be completed by the end of March / early April 2016. The collar locations of holes drilled to date by Sandfire at Monty, for which assay results have been received by Talisman, are shown in Talisman’s interpreted plan view diagram (see Figure 1 on the following page). Figure 1: Plan view of Monty showing Talisman’s simplified stylised geological interpretation and mineralisation overlaid by drill-hole collar locations of holes drilled to date for which assay results have been received by Talisman. Drill hole collars labelled are newly reported holes. For detailed drill hole information refer to Table 1. Monty - Lower Massive Sulphide Zone Resource definition drilling has progressed at Monty, focused on the definition of the Monty Lower Zone mineralisation and has been aimed at defining the edge and continuity of the mineralisation via an infill program. Latest significant results received by Talisman are: TLDD0048 6.6 metres @ 6.0% Cu and 2.2g/t Au from 371.6m – 378.2m (downhole width, top of intercept is 326m vertically below surface); and 7.8 metres @ 11.0% Cu and 2.5g/t Au from 393.0m – 400.8m (downhole width, top of intercept is 344m vertically below surface). TLDD0063 0.8 metres @ 15.1% Cu and 0.7g/t Au from 440.6m – 441.4m (down-hole width, top of intercept is 385m vertically below surface). TLDD0065 5.0 metres @ 4.2% Cu and 0.7g/t Au from 425.6m – 430.6m (downhole width, top of intercept is 358m vertically below surface). Page 2 of 17 Monty - Upper Massive Sulphide Zone Drilling of the Monty Upper Zone mineralisation was planned to infill the existing drilling, plus test the potential for extensions to the known mineralisation, both to the north-east and south-west, along strike. Latest significant results received by Talisman include: TLDD0056 3.5 metres @ 4.4% Cu and 1.1g/t Au from 186.6m – 190.1m (downhole width, top of intercept is 162m vertically below surface) TLDD0057 7.6 metres @ 3.3% Cu and 1.5g/t Au from 152.0m – 159.6m (downhole width, top of intercept is 133m vertically below surface) Further information is required to understand the context of these latest intercepts and the relationship with the existing interpretation for the Upper Zone mineralisation. However, Talisman considers these latest drill results to be encouraging as they potentially extend the Upper Zone to the north east. Monty Deeps In addition to the resource definition drilling, Talisman has been advised that drill hole (TLDD0051) encountered mineralisation in two intercepts which Talisman interprets as being below the currently interpreted extent of the Monty Lower Zone: TLDD0051 1.5 metres @ 4.7% Cu and 1.8g/t Au from 518.6m – 520.1m (down-hole width, top of intercept is 441m vertically below surface); and 7.6 metres @ 3.2% Cu and 0.2g/t Au from 547.2m – 554.8m (down-hole width, top of intercept is 462m vertically below surface. The first intercept is located approximately 80m vertically below the currently interpreted extent of the Monty Lower Zone. Whilst it is too early to draw conclusions as to the relationship between these intercepts and either the Monty Lower Zone or the potential for them to be associated with Monty Deeps, Talisman is encouraged by the result of this exploration drilling and other previously reported intercepts in this area. Further drilling information and results are required to be received by Talisman in order to better understand the context of all of these intercepts and the relationship with the existing interpretation for the mineralisation at Monty. Page 3 of 17 Figure 2: Vertical Longitudinal Projection and simplified interpretation, by Talisman, of the Monty discovery with drill-hole pierce points at the top of the interpreted primary intercept. All intercepts are shown as down-hole widths. New intersections (not previously reported) are shown with white labels and larger dots on the Vertical Longitudinal Projection. Refer to Table 1 and Table 2 for previously released results and new intersections. A Significant Intersection is defined as any intersection ≥ 3m estimated true width that has a grade of ≥ 2.0 % Cu, inclusive of non-mineralised material. Intersections that are <3m estimated true width are defined as significant if the overall grade remained >2.0% Cu when non-mineralised material has been included at a grade of 0.0% Cu (weighted by width) until a 3m estimated true width is reached. Other Regional Exploration Activity As noted in Talisman’s prior releases, in addition to the resource drilling of the Monty mineralisation, joint venture exploration activities are planned to continue at the Springfield Project. Planned joint venture exploration activities advised to Talisman include: • RC drilling to the north east of Monty along the prospective Monty Trend; • RC drilling of geochemical anomalies at Monty South and the Southern Volcanics; • First pass drilling and assessment of the newly identified Monty Deeps; • Continued exploration along the Homer Corridor, including DHEM of TLDD0068; and • Infill aircore drilling at Monty South and first pass aircore drilling of a potential structural exploration target in the north east of the Springfield Project. Priority has been given, by Sandfire, to the completion of Monty resource definition drilling over the past months. Page 4 of 17 Consequently, the timing of the abovementioned planned exploration activities at Springfield is dependent on the amount, availability and allocation of the drilling resources employed by Sandfire on behalf of the Joint Venture. Farm-in / Joint Venture Agreement As announced in Talisman’s ASX release on December 17 2015, Sandfire has reached the $15 million expenditure threshold and an unincorporated Joint Venture has been formed between Talisman and Sandfire. Formal transfer of Sandfire's initial 51% interest in the Joint Venture was completed in December 2015. Formal transfer of Sandfire’s final 19% interest in the Joint Venture has now been completed following the satisfactory audit of the further $5 million of sole funded exploration expenditure by Sandfire at Talisman’s Doolgunna Projects. Talisman is continuing discussions with Sandfire to agree and finalise the terms of an Exploration Joint Venture Agreement under which it will hold a 30 per cent contributing interest in the Doolgunna projects (including the Springfield Project) with Sandfire holding a 70 per cent interest and managing the Joint Venture.

Page 10 of 17 Appendix 1: JORC Table 1 Section 1 Sampling Techniques and Data (Criteria in this section apply to all succeeding sections) Criteria JORC Code explanation Commentary Sampling techniques • Nature and quality of sampling (e.g. 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. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • 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 (e.g. ‘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 (e.g. submarine nodules) may warrant disclosure of detailed information. • The sampling method employed by Sandfire i s h a l f -core sampling of NQ2 core from diamond drilling (DD). • Sandfire collect RC samples by cone splitter for single metre samples or a sampling spear for first pass composite samples using a face sampling hammer with a nominal hole diameter of 140mm. • Sampling is guided by Sandfire protocols as per industry standard. • Diamond drill core sample size reduction is through a Jaques jaw crusher to -10mm and a second stage reduction via Boyd crusher to -4mm. Representative sub samples are split and pulverised via an LM5 mill. • RC samples are crushed to -4mm through a Boyd crusher and representative sub samples are split and pulverised with an LM5 mill. • Pulverising is to nominal 90% passing -75µm and is 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 (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, facesampling bit or other type, whether core is oriented and if so, by what method, etc.). • Diamond drilling is completed using NQ2 size coring equipment. • Method of recording and assessing core and chip sample recoveries and results assessed. • Measures taken to maximise sample recovery and ensure representative nature of the samples. • Whether a relationship exists between sample recovery and grade and • 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 percentage of core recovered. • Appropriate measures are taken to maximise sample recovery and ensure the representative nature of the samples. This includes diamond core Drill sample recovery • RC drilling is with a face sampling hammer of a nominal 140mm hole diameter. • All core, where possible is oriented using a Reflex ACT II RD orientation tool.

RC sample recovery is good with almost no wet sampling in the project area. Samples are routinely weighed and the information captured into the central secured database. No sample recovery issues have impacted on potential sample bias. Geological logging is completed for all holes and is 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 is both qualitative and quantitative depending on field being logged. All cores are photographed. All drill holes are fully logged. • 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. • Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) photography. • The total length and percentage of the relevant intersections logged. • Subsampling techniques and sample preparation • If core, whether cut or sawn and whether quarter, half or all core taken. • If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry. • For all sample types, the nature, quality and appropriateness of the sample preparation technique. • Quality control procedures adopted for all sub-sampling stages to maximise representivity of 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. • Whether sample sizes are appropriate to the grain size of the material being sampled. Quality of assay data and laboratory tests • The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. • Diamond core orientations are completed where possible and all core is marked prior to sampling. Half core samples are produced using an Almonte Core Saw. Samples are weighed and recorded. • RC samples are split using a cone or riffle splitter. The majority of samples collected are dry. On occasion that wet samples are encountered they are dried prior to splitting with a riffle splitter. • All samples are sorted, dried at 80° for up to 24 hours and weighed. Samples are then crushed through a Jaques crusher to nominal -10mm. A second stage crushing is through a Boyd crusher to nominal -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. • 1:20 grind quality checks are completed for 90% passing 75%µm criteria to ensure representativeness of sub-samples. • Sampling is carried out in accordance with Sandfire protocols as per industry best practice. • No field duplicates have been taken. • The sample sizes are considered appropriate for VHMS and gold mineralisation types. • 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 Logging • • • Page 12 of 17 Criteria JORC Code explanation Commentary • 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. • Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. • • • Perchloric acids and analysis 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
