Talisman Mining Limited (ASX: TLM , Talisman ) advises that the Springfield Joint Venture ( Springfield ) (Talisman 30% and Sandfire Resources NL 70% (ASX: SFR , Sandfire )), has approved a $1.2 million budget (100% basis) for the quarter ending December 2017 with work scheduled to commence in the coming weeks. This budget is separate to expenditure on the ongoing development of the Monty Copper-Gold Mine ( Monty ).

The December quarter exploration budget focuses predominantly on testing various new geological interpretations at Monty NE, Monty East and Homer South, along with geochemical anomalies identified within the Southern Volcanics.

This planned work continues from the previous quarter which was primarily focused on detailed geological reviews, and the interpretation and assessment of Induced Polarisation ( IP ) geophysical data collected over the Monty and Monty NE areas. Joint Venture exploration efforts continue to re-evaluate and reinterpret geological, geochemical and geophysical data on an ongoing and iterative basis to maximise discovery opportunities within the Springfield area.

Springfield exploration during budget period 1 July to 30 September 2017

Work completed at Springfield over the three-month budget period ending 30 September 2017 was primarily focused on an internal data review, and evaluation of the geological interpretations provided by Talisman to the Joint Venture late in the June 2017 quarter. On-ground exploration was limited to five RC drill holes for a total of 2,096 metres as depicted in Figure 1.

Reverse Circulation Drilling

Drilling completed at Monty NE, Monty South and within the Southern Volcanics trend targeted bottomof-hole (BOH) lithogeochemical anomalies identified in previous air-core drilling. The three holes completed at these targets (TLRC0070, TLRC0071 and TLRC0073) did not return any significant Cu mineralisation.

The two RC drill holes completed at Monty West (TLRC0069 and TLRC0072) were designed to confirm the position of the Monty host stratigraphy to the west of the Mataro Fault which is interpreted to truncate the Monty mineralisation. The host horizon was successfully intersected in both holes, confirming the interpreted position of host stratigraphy to the north of previous interpretations (Figure 2).

==> picture [455 x 300] intentionally omitted <==

Figure 2: Monty offset geological interpretation showing updated geological interpretation tested during the budget period.

With the addition of this new geological information, Sandfire completed a reinterpretation of this area including a review of the orientation of the Mataro Fault structure. This work included detailed relogging of RC and diamond drill core in the area, including TLDD0114 which was drilled to provide a deep downhole electromagnetic (DHEM) survey platform below the existing Monty Cu-Au mineralisation.

The review resulted in a significant steepening of the interpreted dip of the Mataro Fault as illustrated in Figure 3. As a consequence, the deep diamond drill hole TLDD0114 is now interpreted to intersect the host stratigraphy to the west of the Mataro Fault structure. The DHEM survey of TLDD0114 is now interpreted to have provided geophysical coverage off-hole of TLDD0114 and immediately to the west of the Mataro Fault. There were no geochemical or geophysical indicators observed in the existing RC or deep diamond drilling completed to date.

Given that the purpose of the proposed third deep diamond hole in this area was designed to test the western side of the Mataro Fault and this outcome is interpreted to have been achieved by TLDD0114 (Figure 3), the third proposed deep diamond hole is suspended at this time.

Other Activities

In addition to the recent drilling activities, other exploration was focused on the completion of a detailed review of the ground-based IP orientation survey over the Monty deposit and Monty NE air-core anomaly. The survey consisted of a limited orientation survey, comprising two lines across Monty NE for 1.8km of data, and four lines across the Monty deposit for 7.8km of data.

The trial IP survey over the Monty deposit confirmed that massive sulphides at Monty are sufficiently polarisable to produce a measurable signal from surface. However, from a targeting perspective, the presence of secondary anomalies significantly reduces the reliability of subsequent targets and therefore any targets from an IP survey are likely to require additional justification for follow-up drilling.

The survey of the Monty NE air-core anomaly (5m interval at 4.11% Cu in hole TLAC2694[2] ), returned a clear, although weak anomalous chargeable response with a corroborating low resistivity (Figure 4). The limited amount of data (two survey lines), along with the limited deeper drilling in the area makes interpretation of the geometry of the response difficult.

Previous DHEM surveys in adjacent RC drill traverses approximately 200-300m away from the IP anomaly have not identified any off-hole responses in this area.

In the absence of additional information, Sandfire currently interpret this anomaly to be potentially associated with an interpreted east-west striking fault structure. Importantly, the budgeted RC drill hole for the forthcoming quarter is expected to provide an appropriate test of the identified anomaly.

Budgeted exploration for quarter ending 31 December 2017

As noted earlier, budgeted exploration for the forthcoming quarter will predominantly focus on testing newly interpreted target horizons at Monty NE, Monty East, Homer South (Figure 5 and Figure 6), and geochemical anomalies identified within the Southern Volcanics package.

These recent interpretations, are based on Talisman’s assessment of geological, geochemical and geophysical data collected both recently by the Joint Venture and previously by Talisman prior to the discovery of the Monty deposit and the formation of the Springfield Joint Venture.

Talisman incorporated all the relevant datasets, and generated first principles geological interpretations for areas showing quantitative geochemical anomalism. Based on this, a detailed review of all surrounding drilling data was completed to highlight subtle alteration and/or litho-facies changes that may indicate potential prospective host stratigraphic sequences. A review of the effectiveness of the existing drill testing in these areas was the final stage of the Talisman review. These new interpretations were presented to the Joint Venture late in the June 2017 quarter.

==> picture [417 x 382] intentionally omitted <==

Figure 6: Monty East & Monty NE – Talisman interpretation showing new geological interpretation of the prospective host horizon.

Sandfire completed a detailed review of these new proposed exploration opportunities during the September 2017 quarter. RC drill testing of Monty NE, Monty East and the Southern Volcanics, and an infill air-core program over Homer South, are planned as part of the forthcoming December 2017 quarter budget activities.

Drilling at Homer South is aimed at infilling in an area with only wide spaced historical vertical RAB drill coverage (Figure 7). A complete geological review and reinterpretation based on detailed gravity data is currently underway, with air-core drilling information to be integrated into this new geological interpretation as it becomes available. A target generation process will follow once the air-core drilling is complete.

Talisman is encouraged by the proposed on-ground exploration activities for the December 2017 quarter, and will continue to work together with Sandfire to ensure that maximum value is extracted from the available data. Talisman expects more work to follow-on as the Joint Venture continues to build its geological understanding of this highly prospective, complex project area.

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 and AC sample size reduction is completed through a Boyd crusher to -4mm 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 is completed with a face sampling hammer of nominal 140mm size, AC drilling is with a blade bit 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 98%. • 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.	• 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™.

• 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.

• • AC samples consist of 5m composite spear samples produced from 1m. Additional 1m sampling may be completed depending on the results from the 5m composites samples.

• 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 75µm.

• RC and AC samples are Boyd crushed to -4mm and pulverised using LM5 mill to 90% passing 75 µm.

• Sample splits are weighed at a frequency of 1:20 and entered into the job results file.

• 1:20 grind quality checks are completed for 90% passing 75µm criteria using wet sieving technique 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.

• • 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.

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.	• 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.	• 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 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 Springfield Project is included in Table 1 Drill-hole Information Summary, Springfield Project.

Criteria	JORC Code explanation	Commentary
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 reported from the Springfield Project 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 2: 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 drill-holes. Given the variable, and often steeply dipping orientation of the mineralisation, the angle between mineralisation and drill-holes is not consistent. Downhole intercepts for each drill-hole 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 drill-hole) as well as the dip and azimuth of the drill-hole at that position.
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 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;	• 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.
