Doolgunna Projects (JV with Sandfire Resources NL)
The Doolgunna Projects Joint Venture between Talisman Mining Ltd (the “Company” (ASX: TLM)) and Sandfire Resources NL (“Sandfire” (ASX: SFR)) encompasses the Springfield Project (30%:70%, TLM:SFR) and Halloween West Project (19%:81%, TLM:SFR ) which are high quality VMS copper-gold exploration projects in the Bryah Basin region of Western Australia (see Appendix 1). The recent discovery of exceptionally high-grade copper-gold mineralisation and maiden high-grade Mineral Resource estimate at Monty has confirmed the significant exploration potential of the projects.
Springfield Project
Exploration activities undertaken by the Joint Venture during the quarter focused on the definition of the Monty copper-gold discovery and Maiden JORC 2012 compliant Mineral Resource estimate.
During the March quarter, the Joint Venture completed 12,662m of Diamond, 7,019m of Reverse Circulation RC) and 9,184m of Aircore Drilling, (see Table 2) .
Maiden Monty Mineral Resource Estimate
Subsequent to the end of the quarter, Talisman announced on 13 April 2016 that on behalf of the Springfield Joint Venture, Sandfire had reported a maiden JORC 2012 compliant Indicated and Inferred Mineral Resource for the Monty copper-gold deposit ( see TLM ASX Announcement maiden Monty Mineral Resource Estimate 13 April 2016 ).
The JORC Indicated and Inferred Mineral Resource is 1.05 million tonnes grading 9.4% copper and 1.6g/t gold[1] and includes a high-grade massive sulphide component of 763,000t grading 12.1% Cu and 2.1g/t Au for 92,000t of contained copper and 52,000oz of contained gold[1] . The Monty Mineral Resource estimate is set out in Table 1 .

The Mineral Resource estimate for the Monty Deposit was completed by Sandfire’s internal geological team, and reviewed by independent external contractors, Cube Consulting. The geological model and Mineral Resource estimate were based on the data from 82 diamond drill holes completed by contractor DDH1 Drilling. The drilling was completed on a nominal 30m by 40m spacing to provide sufficient confidence in the model to progress the project towards a maiden Ore Reserve estimate.
Ninety-nine percent of the tonnes contained in the resources, or over 1.04 million tonnes, is classified as Indicated Resource and is available for conversion to Ore Reserves after completion of the appropriate ongoing studies and application of modifying factors.
Monty Deposit Geology
Copper and gold mineralisation at the Monty Deposit is hosted in a sequence of sediments (siltstone, sandstones and conglomerates) and basaltic rocks. Mineralisation occurs in a series of massive sulphide lenses that are interpreted to have been deposited at different stratigraphic levels within the sedimentary package.
The modelled mineralisation at Monty is contained within seven stacked lenses of massive sulphide (see Figure 1 ) that encapsulate the massive sulphide mineralisation. Over 87% of the contained metal is within two main lenses.
==> picture [493 x 292] intentionally omitted <==
Figure 1: Monty Mineral Resource showing all modelled mineralisation[1] .
Adjacent to these massive sulphide lenses, the host sequence shows moderate to strong chlorite alteration with disseminated and/or blebby sulphides throughout. This zone of altered, sulphidic host rock is known as ‘halo mineralisation’.

==> picture [595 x 60] intentionally omitted <==
Sandfire have modelled halo mineralisation, both internal to the main massive sulphide lenses and as an external skin that sits directly adjacent to the high-grade massive sulphides. Based on the available drilling, the highly altered sulphidic halo mineralisation has been interpreted by Sandfire to extend below the limits of the modelled massive sulphide lenses ( see Figure 2 ).
Talisman believes that the presence of this highly altered sulphidic halo mineralisation interpreted below the limits of the modelled massive sulphide lenses highlights the importance of the planned program of deep diamond drilling and subsequent down-hole EM geophysical survey which is aimed at testing the areas down-dip and down-plunge of the Monty Deposit.
Talisman also notes that two separate lenses of high-grade bornite mineralisation have been modelled by Sandfire within the two main massive sulphide lenses. With only four holes intersecting these lenses of high tenor mineralisation, Sandfire have been careful to limit the interpreted extent of this material.
Mineralisation in these bornite-containing zones is of significantly higher tenor than that in the normal (i.e. non-bornite containing) massive sulphide zones. Based on drill-hole geometry and core observations, the bornite zones are interpreted by Sandfire to be approximately orthogonal to lithological layering.
Further work is required to better define and understand the bornite mineralisation, with the Joint Venture considering further drilling as part of future studies to further understand the potential extent of the bornite mineralisation and determine if there is a strategic opportunity to mine direct shipping ore (DSO).
Monty Development Studies
A number of high-level studies for the Monty Deposit are underway by the Joint Venture to investigate the optimal pathway to unlock the value of the project and optimise its development. Results of these studies will define the scope of further, more detailed technical work and the scope of a Feasibility Study. Work programs currently underway include:
-
Metallurgical test work to define ore processing parameters and potential ore processing pathways;
-
Geotechnical and hydrogeological drilling and test work;
-
Mining studies;
-
Regulatory approvals; and
-
Infrastructure studies.
In addition to the above, the Joint Venture is planning to undertake a targeted structural drilling program aimed at providing detailed information to allow the development of a structural geological model to provide context on the location and setting of the Monty Deposit.

Exploration and Resource Definition Drilling
The focus of exploration activities for the quarter was the definition drilling of the Monty Deposit, which culminated in the estimation of the maiden JORC 2012 compliant Mineral Resource[1] . Results from holes drilled during the quarter are continued within Table 4 , and include:
TLDD0051
-
1.5 metres grading 4.7% Cu and 1.8g/t Au from 518.6m (down-hole width); and
-
7.6 metres grading 3.2% Cu and 0.2 g/t Au from 547.2m (down-hole width)
TLDD0057
- 7.6 metres grading 3.3% Cu and 1.5g/t Au from 152.0m (down-hole width)
TLDD0065
- 5.0 metres grading 4.2% Cu and 0.7g/t Au from 425.6m (down-hole width)
TLDD0072
-

TLDD0077
-
4.4 metres grading 3.6% Cu and 1.4g/t Au from 180.7m (down-hole width); and
-
2.1 metres grading 13.4% Cu and 2.3g/t Au from 189.5m (down-hole width)
TLDD0085
- 12.4 metres grading 8.1% Cu and 2.7g/t Au from 359.5m (down-hole width)
TLDD0091
- 3.9 metres grading 7.2% Cu and 1.3g/t Au from 531.0m (down-hole width)
TLDD0108
- 4.9 metres grading 2.9% Cu and 2.4g/t Au from 56.2m (down-hole width)
While timing differences in the receipt of all assay results and the cut-off date for data used in the Monty Mineral Resource has resulted in some of the current assay results being excluded from the estimation process; Talisman believes that there is no material impact on the maiden Monty Mineral Resource.
For results prior to the March 2016 quarter, please refer to the December 2015 Quarterly Activities Report.

Figure 2: Talisman’s Diagrammatic Vertical Longitudinal Projection of the Monty resource wireframes highlighting holes completed during the quarter and selected intersections.
The diagrammatic Vertical Longitudinal Projection depicted in above displays the seven separate modelled massive sulphide mineralisation lenses and two modelled halo mineralisation lenses projected horizontally onto a vertical plane. The massive sulphide component of the Monty Deposit comprises a series of seven individual stacked lenses that overlap in the vertical plane of this schematic representation.
Pierce points are shown at what Talisman interprets to be the uppermost point of the drill hole intersection with the interpreted primary mineralisation lens and are projected horizontally onto the vertical plane. Where a drill hole has not intersected mineralisation (i.e. no significant results returned), a pierce point has been derived by Talisman by extending the trace of the primary mineralisation lens up or down dip as required, to intersect the barren hole. This point has then been projected horizontally onto the vertical plane.
A significant intersection is defined here as any intersection ≥ 3m estimated true width that has a grade of ≥ 2.0 % Cu, inclusive of non-mineralised material. To determine whether intersections that are <3m estimated true width are significant in terms of the above definition, non-mineralised material has been included at a grade of 0.0% Cu (weighted by width) until a 3m estimated true width is reached. If the overall grade remained >2.0% Cu, with the non-mineralised material included, then the intersection is considered significant.

Regional Exploration
The discovery and delineation of the high-grade Monty Deposit opens up a highly prospective new corridor with excellent potential for additional VMS discoveries and has provided invaluable information and insights which will help to refine and target ongoing exploration programs.
Whilst the focus of activities during the quarter was on the Monty delineation drilling, other exploration work outside of the confines of the Monty Deposit was undertaken by the Joint Venture ( see Figure 3 ).
North East Monty Trend
Nine Reverse Circulation drill holes along the NE Monty Trend were completed by the Joint Venture during the quarter.
Importantly, DHEM surveys are planned to be undertaken on all of these holes and interpretation of the area will commence on receipt of all of the assays and DHEM surveys.
Regional RC Geochemistry Program
Drilling commenced across the Springfield Project area as part of the Regional RC Geochemistry Programme to follow up favourable geology and anomalous geochemistry intersected in first pass Aircore drilling.
Three drill holes have been completed during the quarter, with assays pending.

Planned Exploration
In addition to the follow-up work from activities undertaken in the quarter, Sandfire have advised that a focused exploration program outside of the Monty Deposit, aimed at testing the wider regional Springfield Project area has now commenced or is planned to commence shortly.
Planned work includes:
-
A systematic Aircore drilling program to accurately delineate the interpreted VMS host horizon within the Monty area;
-
RC drilling (with diamond tails where required) within the interpreted VMS host horizon along strike from the Monty Deposit;
-
Diamond drilling and subsequent DHEM geophysical survey aimed at testing for potential down-dip and down-plunge extensions of the Monty Deposit;
-
RC and DHEM surveys along the Homer trend where previous drilling has intersected a thick sequence of exhalative rocks interpreted to be analogous to the DeGrussa host stratigraphy; and
-
Systematic Aircore drilling over the Southern Volcanic trend to accurately define the prospective VMS horizon.

Farm-In / Joint Venture Agreement
As previously announced, Sandfire reached the $15 million expenditure threshold in the December quarter and an unincorporated Joint Venture was formed between Talisman and Sandfire at that time.
Formal transfer of Sandfire's initial 51% interest in the Joint Venture was completed in December 2015.
Following satisfactory audit of the further $5 million of sole funded exploration expenditure by Sandfire at Talisman’s Doolgunna Projects, formal transfer of Sandfire’s final 19% interest in the Joint Venture was completed during the March quarter.

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 Springfield Project and 19% interest in the Halloween West Project, with Sandfire holding the remaining interest and managing the Joint Venture.
Sinclair Nickel Project (100% Talisman)
The Sinclair Nickel Project is located in the prolific Agnew-Wiluna Greenstone Belt in WA’s North-eastern Goldfields. The Sinclair nickel deposit was discovered in late 2005, developed and commissioned in 2008 and operated successfully before being placed on care and maintenance in August 2013, having produced approximately 38,500 tonnes of nickel at an average life-of-mine head grade of 2.44% Ni. The Sinclair Nickel Project has extensive infrastructure and includes an extensive 290km[2] tenement package covering at least five known ultra-mafic volcanic sequences considered prospective for massive nickel sulphide mineralisation.
Work continued throughout the quarter to interpret drilling results from the Company’s maiden exploration program completed in the previous quarter.
Priority targets within the Sinclair Nickel Project remain to be tested at numerous prospects including Fly Bore and Delphi with ongoing exploration programs such as surface MLEM, geochemistry and bedrock drilling being developed for these areas.
While Talisman is focusing the majority of available resources on the exploration of Monty and wider Springfield Project Joint Venture in the near term, planning is well underway for the next phase of fieldwork at the Sinclair project as part of its counter-cyclical exploration strategy for this key Company asset.
Corporate
The Company successfully raised a total of approximately $16.7 million (before costs) through a strongly oversubscribed share placement, underpinned by a number of existing and new institutional and cornerstone investors (Placement).
The Placement was undertaken with Bell Potter Securities Limited, Euroz Securities Limited and Petra Capital Limited as Joint Lead Managers with the proceeds being raised under the Company’s 15% placement capacity in accordance with ASX Listing Rule 7.1 and an additional 10% placement capacity in accordance with ASX Listing Rule 7.1A.
At the end of the quarter, Talisman had cash reserves of approximately $22.2 million.
Board and Management Changes
During the quarter, the Company’s Chief Financial Officer, Mr Dan Madden, was appointed as acting CEO following the resignation of Mr Gary Lethridge as the Company’s Managing Director.
==> picture [596 x 40] intentionally omitted <==

==> picture [595 x 60] intentionally omitted <==
In light of Mr Lethridge’s departure, the Talisman Board made the decision to appoint highly experienced corporate executive and former investment banker, Mr Jeremy Kirkwood, to the board as non-executive Chairman, replacing Mr Alan Senior who will remain as a non-executive Director.
Mr Kirkwood – who has extensive experience in corporate strategy, investment banking and global capital markets – will provide invaluable strategic input and guidance to the Company’s board and management team.
A highly respected corporate advisor, Mr Kirkwood has been a principal with Pilot Advisory Group and was previously a Managing Director at Credit Suisse, Morgan Stanley and Austock. Mr Kirkwood has primarily worked in public markets, undertaking merger and acquisitions as well as capital raisings for companies principally in the metals and mining, energy and infrastructure sectors.
While initially contemplating an executive search process following Mr Lethridge’s departure from the Company, the Board has decided that Mr Madden will continue as Acting CEO until at least the end of the financial year when the situation will be reviewed.
The Board believes that Mr Madden has demonstrated the required skills and experience to lead the Company at this time and that this is the best option for the company at this juncture given the focus on the assessment of development options for Monty and the further exploration of Springfield under the Joint Venture with Sandfire.
Mr Madden has been with Talisman since 2009 and has played a key role in all of the key corporate transactions and capital raisings undertaken by the Company over the past six years. Mr Madden has more than 15 years’ experience in the resource sector, including as Financial Controller for Jubilee Mines and General Manager – Finance for Xstrata Nickel Australasia.
The Board believes that Mr Madden’s strong and disciplined leadership, collegiate approach and strong work ethic will serve the Company extremely well moving forward, with appropriate support from the new Chairman and Board.

Table 4 : Drill-hole Assay Intersections >1% copper for the Springfield JV Project
Details of relevant intersections received during the March 2016 quarter at the Springfield JV Project received by Talisman are provided below. Estimated true widths have been calculated using estimated dip and dip-direction of modelled mineralisation surfaces at the drill-hole intersection and azimuth and dip of the drill-hole.
Calculation of relevance for inclusion into this table is based on a 0.5% Cu cut-off, no more than 3m of internal dilution and a minimum composite grade of 1%Cu. Intersection length, Cu (%), Au (ppm), Ag (ppm) and Zn (%) are rounded to 1 decimal point.

Note: For the purposes of Figure 2, 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.

| *During the December 2015 quarter, Sandfire provided a formal Notice to Talisman stating it had sole-funded a total of $15 million of exploration expenditure in order to earn 70% interest in Talisman’s interest in the Doolgunna Projects. Following the satisfactory audit of this expenditure a formal transfer of the final 19% interest in the Doolgunna Projects from Talisman to Sandfire was registered with the Department of Mines and Petroleum on 12 March 2016. _ Tenement P52/1241 was surrendered by the Joint Venture. *** Under compulsory surrender provisions of Section 65(3) of the Mining Act 1978 (as amended), all exploration licences applied for on_ or after 10 February 2006 must be reduced by at least 40 per cent at the end of the sixth year of their term. In consultation with Joint Venture partners, Sandfire Resources NL, the areas interpreted to be least prospective for the discovery of economic mineralisation within E52/2466 were identified and in compliance with the compulsory surrender provisions of the Mining Act 1978 (as amended) subsequently surrendered 40% of the land holding of tenement E52/2466 during the quarter. |

Appendix 4: 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 3kg 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. |
Sampling techniques employed by Sandfire on the Doolgunna Project include half core sampling of NQ2 Diamond Drill (DD) core, Reverse Circulation (RC) drilling samples collected by a cone splitter for single metre samples or sampling spear for composite samples, and Air Core (AC) sample collected using spear techniques for both composite and single metre samples. Sampling is guided by Sandfire DeGrussa protocols and QAQC procedures as per industry standard. RC sample size reduction is completed through a Boyd crusher to -10mm and pulverised via LM5 to nominal - 75µm. Pulp size checks are completed. Diamond core size reduction is through a Jaques jaw crusher to -10mm and all samples Boyd crushed to - 4mm and pulverised via LM5 to nominal 90% passing - 75µm 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, face-sampling bit or other type, whether core is oriented and if so, by what method, etc). |
Sandfire drilling is completed using industry standard practices. RC drilling with a face sampling hammer of nominal 140mm size and diamond drilling is completed using NQ2 size coring equipment. All drill collars are surveyed using RTK GPS. 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. Measures taken to maximise sample recovery and ensure representative nature of the samples. 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. |
Sandfire core is meter marked and orientated to check against the driller’s blocks, ensuring that all core loss is taken into account. Diamond core recovery is logged and captured into the database with weighted average core recoveries of approximately 99%. Surface RC sampling is good with almost no wet sampling in the project area. AC drilling recovery is good with sample quality captured in the database. Samples are routinely weighed and captured into a central secured database. No indication of sample bias with respect to recovery has been established. |
| 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. Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) photography. The total length and percentage of the _relevant intersections logged. _ |
Sandfire geological logging is completed for all holes and is representative across the ore body. The lithology, alteration, and structural characteristics of drill samples are logged directly to a digital format following standard procedures and using Sandfire DeGrussa geological codes. Data is imported into the central database after validation in LogChief™. Logging is both qualitative and quantitative depending on field being logged. |

|---|---|---|
| All drill-holes are logged in full. All cores are digitally photographed and stored. |
||
| Sub-sampling 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. |
Sandfire DD Core orientation is completed where possible and core is marked prior to sampling. Half core samples are produced using Almonte Core Saw. Samples are weighed and recorded. 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. All samples are dried at 80° for up to 24 hours and weighed. DD Samples are then crushed through Jaques crusher to nominal -10mm. Second stage crushing uses Boyd crusher to nominal -4mm. Pulverising is completed using LM5 mill to 90% passing 75%µm. RC samples are 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. 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. The sample size is appropriate for the VHMS and Gold mineralisation styles. |
| 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. 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. |
Sandfire 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. No geophysical tools are used in the analysis. Sandfire DeGrussa QAQC protocol is considered industry standard with standard reference material (SRM) submitted on regular basis with routine samples. SRMs and blanks are inserted at a minimum of 5% frequency rate. |
| Verification of sampling and assaying |
The verification of significant intersections by either independent or alternative company personnel. The use of twinned holes. Documentation of primary data, data entry procedures, data verification, data storage |
Sandfire primary data is captured on field tough book laptops using Logchief™ Software. The software has validation routines and data is then imported into a secure central database. The primary data is always kept and is never replaced |

by adjusted or interpreted data. | |
| Location of data points |
Accuracy and quality of surveys used to locate drill-holes (collar and down- hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. Specification of the grid system used. Quality and adequacy of topographic control. |
Sandfire DeGrussa Survey team undertakes survey works under the guidelines of best industry practice. All surface drilling is located using RTK-GPS. All drill collars are accurately surveyed using RTK GPS system within +/-50mm of accuracy (X, Y, Z). For the Springfield project MGA94 Zone 50 grid coordinate system is used. Topographic control was established using LiDar laser imagery technology. |
| Data spacing and distribution |
Data spacing for reporting of Exploration Results. Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. Whether sample compositing has been _applied. _ |
Infill drilling on a nominal 30m x 40m grid. Exploration drill spacing and distribution of exploration results is not sufficient to support Mineral Resources or Ore Reserves at this stage. No sample compositing has been applied to the exploration results. |
| Orientation of data in relation to geological structure |
Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
No significant orientation based sampling bias is known at this time. The drill holes may not necessarily be perpendicular to the orientation of the intersected mineralisation. |
| Sample security |
The measures taken to ensure sample security. |
Appropriate security measures are taken to dispatch samples to the laboratory. Chain of custody of samples is being managed by Sandfire Resources NL. Samples are stored onsite and transported to laboratory by a licenced transport company in sealed bulker bags. The laboratory receipts received samples against the sample dispatch documents and issues a reconciliation report for every sample batch. |
| Audits or reviews |
The results of any audits or reviews of sampling techniques and data. |
Sandfire have not completed any external audits or reviews of the sampling techniques and data. |

Section 2 Reporting of Exploration Results
(Criteria listed in the preceding section also apply to this section)
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Mineral tenement and land tenure status |
Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. |
The Sinclair Nickel Project is held 100% by Talisman Nickel Pty Ltd, a wholly owned subsidiary of Talisman Mining Ltd. There are no known Native Title Claims over the Sinclair Nickel Project. All tenements are in good standing and there are no existing known impediments to exploration or mining. |
| Sandfire Resources NL and Talisman Mining Limited have formed a Joint Venture which covers Talisman’s Doolgunna Project tenements (E52/2282, E52/2313, E52/2466, E52/2275). Sandfire and Talisman hold a 70%:30% interest respectively in the Joint Venture, with the exception of tenement E52/2275 where interests of approximately 81%:19% respectively are held. Both parties are contributing proportionately to expenditure. Sandfire Resources NL has been appointed as the Joint Venture Manager. All tenements are current and in good standing. The Talisman tenements are currently subject to a Native Title Claim by the Yungunga-Nya People (WAD6132/98). Sandfire currently has a Land Access Agreement in place with the Yungunga-Nya Native Title Claimants and have assumed management of Heritage Agreements which were executed by Talisman. These agreements allow Sandfire to carry out mining and exploration activities on their traditional land. |

| Exploration done by other parties |
Acknowledgment and appraisal of exploration by other parties. |
M37/1275 hosts the Sinclair Nickel Mine which was operated by XNAO from 2007-2013 and produced approximately 38,500 tonnes of contained nickel metal. The Sinclair Nickel Deposit was discovered in 2005 by Jubilee Mines NL drill testing a ground EM anomaly. Exploration work on has included diamond, RC and Air Core drilling, ground and downhole EM surveys, soil sampling, geological interpretation and other geophysics (magnetics, gravity). |
| Exploration work at Springfield completed prior to Talisman’s tenure included geochemical soil and rock chip sampling combined with geological mapping. Some targeted RC drilling was completed over gold and diamond targets. |
||
| Geology | Deposit type, geological setting and style of mineralisation. |
The Sinclair project lies within the Archean aged Norseman-Wiluna Greenstone Belt. The Sinclair Nickel Deposit is an example of an Archaean-aged komatiite-hosted nickel deposit, with massive nickel- iron sulphides hosted at or near the basal contact of high-MgO ultramafic lava channels with footwall basaltic volcanic and sedimentary rocks. |
| The Doolgunna Project lies within the Proterozoic-aged Bryah rift basin enclosed between the Archaean Marymia Inlier to the north and the Proterozoic Yerrida basin to the south. |

| The principal exploration targets at the Doolgunna Projects are Volcanogenic Massive Sulphide (VMS) deposits located with the Proterozoic Bryah Basin of Western Australia. |

| 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: easting and northing of the drill-hole collar elevation or RL (Reduced Level – elevation above sea level in metres) of the drill-hole collar dip and azimuth of the hole down hole length and interception depth 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. _ |
Drill hole information relating to the Doolgunna Project is included In Table 3: Drill-hole Information Summary, Springfield Project. |
| Data aggregation methods |
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually material and should be stated. 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. The assumptions used for any reporting of metal equivalent values should be clearly 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. Minimum and maximum DD sample intervals used for intersection calculation are 0.3m and 1.2m respectively. RC reported intersections are based on regular 1m sample intervals. No metal equivalents are used in the intersection calculation. Where core loss occurs; the average length-weighted grade of the two adjacent samples are attributed to the interval for the purpose of calculating the intersection. The maximum interval of missing core which can be incorporated with the reported intersection is 1m. |
| Relationship between mineralisation widths and intercept lengths |
These relationships are particularly important in the reporting of Exploration Results. If the geometry of the mineralisation with respect to the drill-hole angle is known, its nature should be reported. If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (e.g. ‘down hole length, true width not known’). |
Drill-hole intercepts relating to the Doolgunna Project in this release are reported as both down-hole intersection widths and estimated true width intersections (refer Table 4: Drill hole assay intersections >1% for the Monty Prospect). The geometry of the mineralisation has been interpreted using top of mineralisation surfaces that link mineralised zones, thought to be continuous, between neighbouring drillholes. Given the variable, and often steeply dipping orientation of the mineralisation, the angle between mineralisation and drillholes is not consistent. Downhole intercepts for each drillhole are converted to estimated true widths using a trigonometric function that utilises the dip and dip direction of the interpreted top of mineralisation surface (at the intersection point of that drillhole) as well as the dip and azimuth of the drillhole at that position. |
| Diagrams | Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being |
Appropriate maps with scale 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. Other data collection will be reviewed and reported when considered material. |
| Further work |
The nature and scale of planned further work (e.g. 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. |
Additional drilling and geophysical surveys at Sinclair in the future will be dependent on the outcomes of current review of previous exploration results. |
| Planned exploration across the Springfield Joint Venture Project area includes reconnaissance and exploration drilling with Diamond, Reverse Circulation and Aircore drilling techniques. |
