- Springfield Copper Gold Project (Joint Venture with Sandfire Resources NL)
During the June quarter, the focus of joint venture activities at the Springfield Cu-Au Project ( Springfield ) was on the commencement of mining development at the Monty Copper-Gold Project ( Monty ), ongoing exploration within the Monty region and the wider Springfield project, and the mandate of Taurus Mining Finance Fund ( Taurus ) as the debt financier for Talisman’s forecast share of Monty pre-production development costs.
Monty Development
On the 4 July 2017, Talisman received advice that the Western Australian Department of Mines, Industry Regulation and Safety ( DMIRS ) (formerly Department of Mines and Petroleum) had approved the Mining Proposal and Mine Closure Plan for Monty facilitating the commencement of onground earthworks.
Civils and earthworks contractor Yagahong mobilised a portion of its fleet to the DeGrussa site in early June to commence preliminary earthworks at DeGrussa and facilitate the immediate commencement of the Monty boxcut and critical path earthworks once DMIRS approvals were received. Preliminary Monty early works included:
-
relocating existing stockpiled topsoil at DeGrussa in the path of the planned Monty haul road;
-
establishing the water pipeline route at DeGrussa including clearing; and
-
constructing an additional access ramp to the existing DeGrussa ROM pad to allow for roadtrain access from Monty.
Following the receipt of approval for the Monty Mining Proposal, Yagahong mobilised to the Monty site to commenced initial earthworks. Works completed and underway on the Monty site include:
-
the clearing of the haul-road centreline;
-
stripping and stockpiling of topsoil from the Monty boxcut; and
-
commencement of the Monty boxcut (approx. 2m depth as at 20 July 2017) ( Figure 1 ).

mining contractor. The appointment of Byrnecut, who are currently the underground mining contractor at the DeGrussa mine, enables the Joint Venture to leverage off existing Byrnecut infrastructure and experience at DeGrussa.
Monty Development Funding
Following a competitive process, Talisman mandated Taurus in May 2017 to provide debt finance facilities of approximately A$23 million to fully cover Talisman’s share of forecast pre-production costs for the development of Monty.
The selection of Taurus as preferred debt provider was driven by a combination of factors including a highly competitive overall cost of debt, finance facilities covering the full forecast pre-production cost, no mandatory commodity price hedging requirement and flexibility in relation to early repayment and other key terms.
Execution of the final finance facility agreement remains conditional upon satisfactory completion of due diligence and payment of associated facility costs and fees. Due diligence was well progressed by the end of the June quarter and Talisman expects final agreements to be executed in the coming weeks.
Exploration
On-ground exploration activities completed at Springfield during the June quarter included:
-
completion of two deep diamond holes and downhole electromagnetic ( DHEM ) surveys testing beneath the existing Monty Resource;
-
completion of aircore drilling at the eastern end of the Southern Volcanics Trend; and
-
Reverse circulation ( RC ) drill testing of a number of isolated geochemical anomalies.
A detailed review of existing data was undertaken by Talisman during the quarter which generated a number of alternate geological interpretations and subsequent drill targets that are currently under review by the Joint Venture.
Drilling at the Springfield project over the quarter ending 30 June 2017 included 10,595 metres of aircore, 1,278 metres of RC and 1,910 metres of diamond drilling as depicted in Figure 2 . In addition to the recent drilling activities, on-ground exploration was also focused on the completion of a detailed ground-based Induced Polarisation ( IP ) orientation survey over the Monty deposit and Monty North East aircore anomaly and DHEM surveying of RC and diamond holes.

Monty Deeps Diamond Drilling
Two of three planned deep diamond DHEM platform holes ( Figure 2 and Figure 3 ) were completed by the Joint Venture (TLDD0114 and TLDD0115) during the June quarter. Full details of the hole collar locations and intersections are provided in Table 1 and Table 2. The location of the planned third hold was dependent on the drill results and subsequent DHEM surveys of these first two holes and is discussed below. The two holes that have been drilled were designed to test a position approximately 500m below the assumed range of the existing DHEM suveys, to the east of the Mataro fault ( Figure 3 ).
Talisman was advised by the Joint Venture Manager that the two deep diamond the holes were interpreted to have intersected sediment units that correlate with the prospective stratigraphy. No visual copper mineralisation was logged in the drill core. DHEM data was collected from both holes and discussions with the Joint Venture Manager confirmed that no immediate or obvious bedrock anomalism was identified. Final data and reports were received in July and Talisman will complete a detailed review of the DHEM survey report and data during the current quarter.
The effectiveness of DHEM is dependent on many factors, and estimated off-hole coverage is influenced by the size and nature of mineralisation and the continuity of any potential conductive body of mineralisation. Talisman believes the DHEM undertaken to date on the Springfield tenements to be a useful tool for searching for large orebodies within a 100 to 200 metres radius of a surveyed drill hole, but has reduced effectiveness and coverage for smaller, fractured mineralised orebodies.

Figure 3: Monty deposit projected long section with completed and proposed diamond holes and interpreted DHEM coverage.
Importantly, results and observations in the two completed deep diamond drill holes has led to an updated geological interpretation of the fault off-set host stratigraphy to the west of Monty. A number of RC drill holes will be undertaken to test the new interpretation ( Figure 4 ). The first of these RC holes is currently underway and all RC holes will be completed and subject to DHEM surveys in advance of finalising the position for the third deep diamond DHEM platform hole.

Reverse Circulation Drilling
There was limited targeted RC drilling undertaken in the June quarter. Three RC holes were completed, selectively targeting litho-geochemical anomalies identified by the Joint Venture Manager in aircore drilling over Monty South and Monty East ( Figure 2 ).
Results from these holes did not return any significant copper mineralisation. Full details of the hole collar locations and intersections are provided in Table 1 and Table 2. DHEM data has also been collected from these holes, and preliminary advice and discussions with the Joint Venture Manager has confirmed that no immediate or obvious bedrock anomalism was identified. Final reporting of the data is in progress.
Aircore Drilling
Aircore drilling focused on the eastern end of the Southern Volcanics and “boxing-out” isolated single point anomalies identified in previous drilling (Figure 2) to provide bottom-of-hole ( BOH ) samples for litho-geochemical analysis. Results from this analysis are still being received and compiled by the Joint Venture Manager.
An initial review by Talisman of the available aircore drilling at the Southern Volcanics has shown that a significant proportion of holes ended in dolerite, limiting the usefulness of the BOH litho-geochemical processing employed by the Joint Venture Manager as an initial vectoring tool. An alternate targeting methodology may need to be implemented along this 16km long corridor.
Other Activities
A small orientation IP survey was undertaken over the Monty deposit and Monty North East anomaly. Data was successfully collected and is being processed with results expected in the current quarter.
The aim of this survey was to assess the ability of this technique to detect Monty mineralisation from surface which, if successful, could then be applied to other areas of the Springfield project.
September 2017 Quarter Exploration
The Springfield Joint Venture partners have approved a A$1m exploration budget for the September 2017 quarter. Proposed activities in this budget include:
-
Development and testing the current interpreted fault offset of the interpreted Monty horizon to the West of the Monty deposit including RC drilling, a deep diamond drill hole and DHEM on diamond and RC drill holes ( Figure 4 );
-
RC drilling at Monty North East to test a second and separate BOH aircore anomaly in this area;
-
Consideration of new interpretations by Talisman for the position of the prospective host sequence at Monty East, Monty North East and Homer South ( Figure 5 and Figure 6 ) which have been the subject of minimal effective drill testing; and
-
Reassessment and reinterpretation of the existing extensive database.

Sinclair Nickel Project Exploration
A program of aircore drilling targeting the Delphi and Schmitz Well South nickel prospect areas and a gold-in-regolith anomaly identified from historic RAB drilling at Sturt Meadows commenced during the quarter. A total of 306m of the planned 8,600m was completed at the end of June.
Delphi Prospect
The Delphi prospect is located on the Sinclair Ultramafic Trend approximately 8km south of Sinclair and 2.5km south of recent successful drilling results at Delphi North.
A series of aircore drilling traverses are planned across an area covering approximately 500m of prospective ultramafic stratigraphy that has not been previously drilled (Figure 7) . This area is interpreted to be highly prospective for hosting massive nickel sulphide mineralisation. Previous drilling along strike to both the north and south highlighted a fertile ultramafic sequence and diamond drill hole SND007 (completed October 2016) intersected stringer and disseminated sulphides.

Schmitz Well South Prospect
A number of aircore drilling traverses are planned at Schmitz Well South to follow up fertile, high-MgO ultramafic units intersected in limited RC drilling undertaken by Talisman in 2016. Drilling will provide geological and geochemical information over the broader trend ( Figure 8 ) and additional detail to drilling already completed.

Sturt Meadows (Au)
A series of three aircore drill traverses commenced during the quarter to test a historic gold anomaly identified from wide spaced, historic RAB drilling completed in the 1990’s ( Figure 9 ). Full details of the hole collar locations and intersections are provided in Table 3 and Table 4. Interpretations from geophysical magnetic data shows the anomaly is in an area of structural complexity located close to a major flexure in the granite-greenstone contact. This area is considered to be a favourable geological environment for hosting significant potential gold mineralisation.

New Project Generation
In conjunction with the development of Monty, exploration activities at Springfield and ongoing exploration at Sinclair, Talisman continues to examine opportunities to add new projects to its portfolio that align with its core exploration expertise.
As part of these activities, Talisman received notification in July 2017 from the New South Wales Department of Planning and Environment, Division of Resources and Energy of the grant of Exploration Licence EL8615, located approximately 70km north of the town of Condobolin within the Cobar/Mineral Hill region of Central NSW. Talisman has also submitted two exploration licence applications to the north east of Cobar ( Figure 10 ).
The Cobar/Mineral Hill region is a richly mineralised district that hosts a number of base and precious metal mines including the CSA mine, Tritton, and Hera/Nymagee. This region contains highly prospective geology that has produced many long-life, high-grade mineral discoveries.

==> picture [596 x 64] intentionally omitted <==
Talisman has completed a review of the historical exploration undertaken within the tenements and has identified a number of areas that show evidence of base and precious metals endowment. These areas have had very little modern exploration completed to date and it is considered that there is significant potential for the discovery of substantial base metals and gold mineralisation.
Initial work by Talisman will include the validation of earlier exploration activities as part of a preliminary phase of work, prior to the commencement of on-ground exploration. It is anticipated that on-ground field work will commence during the last quarter of 2017 or the first quarter of 2018 following the finalisation of land access and other statutory agreements.

Appendix 2: JORC Tables Sections 1 & 2
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 aircore (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. • Sampling techniques employed by Talisman at the Sinclair Nickel Project include saw cut diamond drill core (DD) samples in NQ2 size sampled on geological intervals (0.2 m to 2 m), cut into half (NQ2) core to give sample weights under 3 kg, Reverse Circulation (RC) drilling samples collected by a cone splitter for single metre samples or sampling spear for composite samples, and aircore (AC) sample collected using spear techniques for composite samples or collected by a riffle splitter for single metre samples. • Sampling is guided by Talisman protocols and QAQC procedures as per industry standard • Samples were crushed, dried and pulverised (total prep) to produce a 30g sub sample for analysis by four acid digest with an ICP/AES finish for base metals; and a 50g Fire assay with an AAS finish for gold |

• 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.

||
| 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 1: Drill-hole Information Summary, Springfield Cu-Au Project. • Drill hole information relating to the Sinclair Nickel Project is included in Table 3: Drill-hole Information Summary, Sinclair Nickel 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 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. • Significant intersections reported from the Sinclair Nickel Project are based on greater than 0.5% Ni and may include up to 1m of internal dilution, with a minimum composite grade of 1% Ni. |

|---|---|---|---|
| • Ni grades used for calculating significant intersections are uncut. • A minimum diamond core sample interval of 0.15m and a maximum interval of 1m is used for intersection calculations subject to the location of geological boundaries. • Length weighted intercepts are reported for mineralised intersections. • No metal equivalents are used in the intersection calculations. |
|||
| 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 for the Springfield Cu-Au Project). • 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. • Drill holes relating to the Sinclair Nickel Project are reported as down hole intersections (refer to Table 4). True widths of reported mineralisation are not known at this time. |
|
| 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; 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. |
