Monty Development
On-site construction activities for Monty have progressed with pre-production surface and underground infrastructure installed and in-use.
The underground mining contractor, Byrnecut Australia Pty Ltd, continues to progress Monty development and at the end of June 2018 the decline had advanced to 1,013 metres compared to a corresponding feasibility study budget of 1,163 metres (13% under budget). Development advance was slowed during the previous two months as remedial ground support activities were undertaken on areas where poorer ground was intersected and pumping capacity was installed to cater for expected water inflows. It is anticipated that the decline advance will be realigned with the schedule during the forthcoming quarter.
Total development advance was 2,163 metres as at the end of June, compared to the Feasibility Study schedule of 2,508 metres (14% under budget).
First ore production remains on schedule for late in the December 2018 Quarter, with initial stope production now planned to commence in the March 2019 Quarter.

Monty Development Budget
The Joint Venture has recently approved a budget for the period ending 31 December 2018 and a forecast to 30 June 2019 which covers both remaining pre-production capital costs for the development of Monty and production activities to 30 June 2019. Talisman’s share of budgeted and forecast expenditure during this period is $20.1M compared to the forecast costs in the corresponding period of the Monty Feasibility Study of $17.0M. The cost increase is principally attributable to timing differences in pre-production capital spend from the previous budget period and an increase in planned grade control drilling.
A breakdown of the recently approved capital budget compared to the Monty Feasibility Study is provided in Table 1.

Monty Project Financing Facility (PFF)
As previously announced, Talisman has secured a project debt finance facility with Taurus Mining Finance Fund for US$20 million to fund 100% of Talisman’s share of Monty pre-production capital[1] .
Talisman has made two drawdowns to date totalling US$11.5 million. The drawdowns were to cover pre-production costs from 1 July 2017 to 31 March 2018. A further US$8.5M is available to be drawn down against the facility for future pre-production capital costs.
As at 30 June 2018, Talisman held approximately A$0.7M of funds drawn down but not yet called by the Joint Venture Manager. Talisman’s share of the current Monty budget/forecast pre-production capital for the months of April and May 2018 was funded by the existing surplus in funds drawn but not called by the Joint Venture. In accordance with the provisions of the Term Sheet supporting the proposed sale of Talisman’s 30% share of the Springfield JV, effective 5 June 2018 Talisman will not make any further capital contributions to the Springfield JV (including for Monty development) subject to completion of the proposed transaction.
Exploration
Activities at the Joint Venture during the current quarter ended 30 June 2018 have been focused on the completion of infill aircore drilling along the Southern Volcanics trend, and follow-up of a weak geochemical anomaly identified in previous drilling at Homer.
In addition to this on-ground exploration, a project wide review of surface and downhole geophysical data was undertaken.
1 Please refer to TLM ASX announcement “Monty Financing Finalised”, dated 30 October 2017
3
Aircore drilling undertaken along the Southern Volcanics trend (totalling 4,624 metres) was designed to infill previous aircore drilling and provide additional information over newly interpreted host positions. A single reverse circulation ( RC ) hole (TLRC0075) for 448 metres at Homer ( Table 3 ) was designed to test a previously identified geochemical anomaly. Assay results from TLRC0075 did not return any significant mineralisation ( Table 5 ), similarly the infill air-core drilling of the Southern Volcanics did not highlight any areas that require follow-up drill testing.
A review of all available surface and down-hole electromagnetic geophysical survey data ( DHEM ) was completed by an independent consultant group. The review concluded:
-
DHEM detection limits are considered to be good for ‘Monty Style’ mineralisation (approximately 140m from the discovery hole), due to the presence of high conductance pyrrhotite mineralisation.
-
Modelling has indicated that not all parts of Monty mineralisation are conductive, and that the Monty deposit is a difficult electromagnetic target to model due to factors including: size, conductance, steep-dip and depth.
-
Outside of the Monty deposit, only one, low-confidence, single component DHEM anomaly was modelled within the Monty NE trend, at the background noise limits of the survey equipment.
-
A subtle moving loop electromagnetic ( MLEM ) anomaly was recognised adjacent and along strike from the DHEM anomaly, however a further review of this data has concluded that this MLEM anomaly can be attributed to instrument noise and does not require further follow-up.
Budgeted exploration for quarter ending 30 September 2018
The Joint Venture has recently approved a budget for the quarter ending 30 September 2018. Planned exploration during this period includes diamond drilling, to extend an existing historic drill hole, SPD017, by an estimated 60-100 metres ( Figure 3 ); along with an allowance of some 1,350m of unallocated RC drilling. The estimated total Joint Venture exploration budget for the three-month period totals $265,000, on a 100% basis.
The aim of the diamond drilling on SPD017 is to provide a DHEM platform adjacent and closer to the weak single component DHEM signal modelled in the recent geophysical data review. It should be noted that this drill hole extension is not designed to intersect the modelled plate, rather it is specifically designed as an improved geophysical survey platform to allow for an additional DHEM survey.
While Talisman believes that this follow-up work is required; it is again noted that this is a lowconfidence, single component anomaly, at the background noise limits of the survey equipment. Furthermore, Talisman believes the proposed extension and subsequent DHEM survey of SPD017 is an appropriate low-cost test to verify the existence of an anomaly in this area that will be reevaluated once the new survey data is received. Drilling of the SPD017 extension is expected to complete shortly.

Results from infill diamond drilling of the Monty Upper Zone conducted by the Joint Venture Manager during the previous quarter were received in June 2018.
This program provided infill drilling between the existing resource definition drill holes in selected areas. All the completed drill holes into the Monty Upper Zone intersected massive sulphide mineralisation and results show a good correlation with the current orebody model used for the existing Monty JORC Resource.
The pierce points of the recent infill drill holes for which assay results have been received by Talisman, are shown in Talisman’s interpreted long section ( Figure 4 ).

- Lachlan Copper Gold Project
Blind Calf Prospect
The Blind Calf Prospect, comprises a cluster of 13 historic (early 1900’s) mining shafts developed on a series of shear hosted sulphide rich quartz lodes with mapped outcrop strike extents of between 40m to 100m and widths of 5m at surface.
High-grade copper mineralisation was intersected over significant widths during the initial RC drill program at the Blind Calf Prospect in the Lachlan Cu-Au Project in NSW ( Appendix 1 ).
The program comprised seven holes for 984m to a maximum depth of 187m, and intersected quartz veining and sulphide mineralisation in all holes ranging from broad zones of disseminated sulphides (pyrite and chalcopyrite) in siliceous host rocks to zones of foliated quartz veining with up to 50% sulphides logged in drill cuttings.
Results included wide zones of high-grade mineralisation within sulphidic quartz veins and show a broadening of the Blind Calf copper lode at depth, as well as a significant increase in the grades compared to those reported by previous explorers ( Figure 5 ).
Best results (Table 4 and Table 6 ) included:
- BCRC005: 7m @ 5.68% Cu, from 98m down hole
Inc. 4m @ 7.85% Cu from 100m down hole;
o BCRC006: 13m @ 5.71% Cu, from 129m down hole
Inc. 4m @ 11.06% Cu from 136m down hole
- BCRC007: 11m @ 4.78% Cu, from 127m down hole
Inc. 4m @ 8.40% Cu from 127m down hole;
Copper mineralisation at Blind Calf is associated with a sheared quartz lode system with moderate sulphide mineralisation (chalcopyrite/pyrite) logged in RC drill chips. The main quartz lode is encased in a zone of altered siliceous host rock with disseminated sulphides, which has returned copper grades of between 0.5% – 1% Cu for some distance on both the hanging wall and foot wall. Further drilling, including diamond core, is required and is being planned to fully understand the geological setting and nature of this high-grade copper system.
DHEM surveys were completed on five of the seven drill holes. The survey results have shown several coherent off-hole conductors, which appear to be mapping the high-grade core of copper mineralisation at Blind Calf ( Figure 5 ). The modelled DHEM plates are coincident with the >5% Cu intersections reported in Talisman’s recently completed RC drilling and, importantly, extend downdip beyond the limit of the existing drilling.
A similar, separate, moderate off-hole DHEM anomaly has been modelled in an untested zone beneath the current drill testing of the adjacent Dunbar lode. The presence of this DHEM anomaly is highly encouraging and may represent a similar high-grade core within the Dunbar lode system.

Both new target positions will be drill tested in the follow-up drilling program that is currently being planned to target the identified DHEM anomalies at depth, as well as providing a more systematic fence of RC drilling to extend the know mineralisation lodes at depth and along strike. This program will include diamond drilling to enable structural logging of the lode systems to provide suitable drill core samples for geophysical property analysis.
In parallel with this work at Blind Calf, an extensive auger sampling program was completed subject to the end of the quarter, targeting the SE extensions of the Blind Calf and Mineral Hill Corridors which trend into the adjacent tenement ( Figure 6 ).

Figure 6: Boona Project Area, proposed auger sampling areas, and historic rock-chip results[2]
Historic rock-chip and drilling data from this area has returned high-grade copper, lead and gold mineralisation associated with quartz veining and gossanous iron rich outcrop. Approximately 3,500 auger samples are to be collected and analysed on-site for base metals and sent to the ALS Chemex’s laboratory in Orange, NSW for gold analysis. This data will provide systematic geochemical coverage of the area to better define existing drill targets.

Auger Drilling at Central Lachlan Project Area
The initial analysis of samples from the first phase of auger drilling over the Central Lachlan Project area in NSW ( Appendix 1 ) resulted in the definition of a large, coherent base metal anomaly which extends for approximately 1 kilometre along strike of the regionally significant Gilmore Suture fault zone.
Shallow (<2m) geochemical sampling was conducted on a nominal 300m x 50m grid pattern over selected geological and geophysical target areas ( Figure 7 ). Bottom of hole samples were collected from auger drilling, designed to penetrate the shallow transported cover sequences to allow a consistent residual sample media.
==> picture [327 x 476] intentionally omitted <==
Figure 7: Phase 1 Auger drilling campaign – Central Lachlan Project Area

Initial portable XRF analysis identified a strong coincident copper-zinc-lead anomaly in the northern most area covered by sampling. The anomaly extends over three of the 300 metre spaced traverses and shows consistently high copper, zinc and lead grades for over 400 – 600 metres across strike, defined by greater than 300ppm zinc ( Figure 8 ).
The coincident base-metal anomalies are associated with abundant brecciated and gossanous iron rich quartz vein outcrop and strong manganese alteration of the surrounding host rocks, which is indicative of epithermal style mineralisation.

Figure 8: Auger geochemistry showing Cu (left hand side) and Zn (right hand side) anomalism at Central Lachlan Project Area
The anomaly has a strong correlation with the regionally important NW-SE trending Gilmore Suture fault zone, which hosts economic mineralisation at the Mineral Hill base metal mine to the south east as well as numerous other historic gold and base metal mines to the north and south including the Bobadah, Babinda, Mt Boppy and Blind Calf mining centres ( Appendix 1 ). Importantly, mineralisation in these areas appears to be associated with the intersection of N-S trending structures and NW-SE trending regional structures. These same trends can be observed in the copper, zinc and lead geochemical data, adding further significance to this newly highlighted area.

Sinclair Nickel Project Exploration
Activities for the June quarter included preparation for an RC drilling program of an estimated 1,000m of drilling across three traverses to test a new conceptual target at Skye East ( Figure 9 ). It is currently anticipated that this program will be completed in the September 2018 quarter.
Previous shallow drilling in the area has identified the target ultra-mafic basal contact, with associated disseminated nickel sulphides including:
-
CWD105 – 0.57m @ 1.82% Ni
-
CWD005 – 2.00m @ 1.49% Ni
-
CWD011 – 0.45m @ 0.98% Ni

Corporate
Proposed Sale of Talisman’s 30% Interest in the Springfield JV
Talisman advised on 8 June 2018 that it had reached in-principle agreement for Sandfire Resources NL ( Sandfire ) to acquire Talisman A Pty Ltd ( Talisman A ), the subsidiary company that holds Talisman’s 30% interest in the Springfield JV ( Term Sheet ).
Key terms of the Term Sheet include:
-
Talisman to receive A$72.3M cash consideration.
-
The cash consideration for Talisman A is on a cash-free and debt-free basis. Any debt owed by Talisman A under the Taurus Mining Finance Fund ( Taurus ) facility is to be repaid or discharged by Talisman on or prior to transaction completion. The current drawn amount of the Taurus debt facility is US$11.5M.
-
Provided satisfactory commercial terms can be reached with Taurus, Sandfire will effectively assume, via its acquisition of Talisman A, the existing 2.25% gross revenue royalty held by Taurus over Talisman’s 30% share of Monty, which is capped at the contained copper and gold metal in the current Monty Mineral Resource Estimate ( TMFF Royalty ) with such modifications as Sandfire and Taurus agree.
-
Sandfire to grant to Talisman an uncapped and perpetual 1.0% Net Smelter Return ( NSR ) Royalty applying to 100% of all contained copper and gold in ore mined and processed from within the Springfield JV above the respective contained metal levels in the current Monty Mine Plan (based on the Monty Feasibility Study released in April 2017) ( NSR Royalty ).
-
An effective date of 5 June 2018, resulting in no further capital contributions from Talisman A to the Springfield JV, including for Monty development (subject to transaction completion).
Completion of the proposed transaction is subject to the following key conditions:
-
Satisfaction of confirmatory due diligence by Sandfire, with a view to establishing that there are no material, onerous or unusual agreements or liabilities in relation to Talisman A including a review of the Taurus facility agreement and TMFF Royalty agreement;
-
The preparation and execution of a Share Sale Agreement and NSR Royalty Agreement in a form satisfactory to both parties by 4 August 2018;
-
The unanimous recommendation of the Talisman Board and statement of intention to vote shares held or controlled by the Board in favour of the sale at any requisite Talisman shareholder meeting to approve the sale;
-
An irrevocable statement of intention from Kerry Harmanis to vote shares held or controlled by him (or his Associates) in favour of the sale at any requisite Talisman shareholder meeting to approve the sale;
-
Taurus and certain other Taurus parties providing consent to Sandfire’s acquisition of the shares in Talisman A, the grant to Talisman of the NSR Royalty and the TMFF Royalty remaining on foot on appropriate commercial terms satisfactory to Sandfire and otherwise with such modifications as Sandfire and certain Taurus parties agree;
13
-
Any other conditions arising out of Sandfire’s confirmatory accounting, tax, legal, corporate and human resources due diligence; and
-
Talisman shareholder approval at the requisite Talisman shareholder meeting to approve the sale (including for the purpose of ASX Listing Rule 11.2).
Talisman has been working with Sandfire to satisfy due diligence requirements and enter into a formal Share Sale Agreement acceptable to both parties.
Talisman considers that shareholders' approval is required under Listing Rule 11.2 on the basis that the sale of Talisman A would likely constitute a disposal of Talisman's main undertaking. It is expected that a General Meeting will be convened to be held approximately six to eight weeks after entering into a binding Share Sale Agreement and NSR Royalty Agreement in relation to the proposed transaction.
Subject to successful execution of all formal agreements, satisfaction of all conditions, receipt of Talisman shareholder approval and completion of the sale of Talisman A, Talisman intends to return a substantial proportion of the cash consideration to shareholders after accounting for anticipated retirement of the prevailing Taurus debt facility balance. Talisman will seek to structure this return in the most efficient manner for all Talisman shareholders.
Working Capital Facility
On 28th June Talisman entered into agreement with Taurus for a US$3 million working capital facility ( Facility ) to support Talisman’s current exploration activities and general working capital.
Funds from the Facility will be used to maintain current and planned activity levels on Talisman’s Lachlan Project in NSW, the Sinclair nickel project in WA and for general working capital purposes.
The Facility can be repaid at Talisman’s election without penalty and any drawn amount of the Facility will be repaid from the proceeds of the sale of its share of the Springfield JV, subject to the satisfaction of all conditions.
The Facility has been structured with an expiry date of 30 June 2020, providing Talisman with sufficient flexibility should the proposed sale of its share of the Springfield JV not complete for any reason.
At the end of the quarter, Talisman had requested an initial US$1 million drawdown of the Facility.

About Talisman Mining
Talisman Mining Limited (ASX:TLM) is an Australian mineral development and exploration company. The Company’s aim is to maximise shareholder value through exploration, discovery and development of complementary opportunities in base and precious metals.
Talisman holds a 30% interest in the Springfield Joint Venture with Sandfire Resources NL (70% and JV manager). Springfield is located in a proven VMS province in Western Australia’s Bryah Basin and contains multiple prospective corridors and active exploration activities. Springfield hosts the high-grade Monty copper-gold deposit which is located 10 kilometres from Sandfire’s DeGrussa operations. Monty is one of the highest-grade copper-gold discoveries made globally in recent decades and a Feasibility Study on its development was completed in March 2017. The Feasibility Study highlighted the strong technical and financial viability of Monty. The Monty deposit is currently under development and Talisman has secured project debt financing for 100% of its share of pre-production capital costs.
Talisman also holds 100% of the Sinclair Nickel Project located in the world-class Agnew-Wiluna greenstone belt in WA’s north-eastern Goldfields. The Sinclair nickel deposit, developed and commissioned in 2008 and operated successfully before being placed on care and maintenance in August 2013, produced approximately 38,500 tonnes of nickel at an average life-of-mine head grade of 2.44% nickel. Sinclair has extensive infrastructure and includes a substantial 290km[2] tenement package covering more than 80km of strike in prospective ultramafic contact within a 35km radius of existing processing plant and infrastructure.
Talisman has also secured tenements in the Cobar/Mineral Hill region in Central NSW through the grant of its own Exploration Licenses and through separate farm-in agreements. The Cobar/Mineral Hill region is a richly mineralised district that hosts several base and precious metal mines including the CSA, Tritton, and Hera/ Nymagee mines. This region contains highly prospective geology that has produced many long-life, high-grade mineral discoveries. Talisman has identified a number of areas within its Lachlan Cu-Au Project tenements that show evidence of base and precious metals endowment which have had very little modern systematic exploration completed to date. Talisman believes there is significant potential for the discovery of substantial base metals and gold mineralisation within this land package.

APPENDIX 3
JORC Tables Section 1 & 2
Section 1 Sampling Techniques and Data

(Criteria in this section apply to all succeeding sections)
-
Criteria JORC Code explanation Commentary
-
Sampling • Nature and quality of sampling (e.g. cut • techniques channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down-hole gamma sondes, or handheld XRF instruments, etc.). These examples should not be taken as limiting the broad meaning of sampling.
-
Sampling 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.
-
-
Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used.
-
RC sample size reduction is completed through a Boyd crusher to -10mm and pulverised via LM5 to nominal - 75µm. Pulp size checks are completed.
-
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.
-
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. 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. • Sinclair drill samples were submitted to ALS Chemex Laboratories in Perth for multi-element analysis using a 1g charge with a multi-acid digest and ICP-MS or AAS finish (OG62). Analytes include Al, Fe, Mg, Mn, S, Ti, Ag, As, Co, Cr, Cu, Ni, Pb, V, Zn, Zr. • Samples are analysed for Au, by firing a 50g of sample with AAS finish • QAQC protocols for all drill sampling involved the use of Certified Reference Material (CRM) as assay standards. The insertion ratio of CRM standards was 1 in 33 with a minimum of two per batch. OREAS and Geostats standards are selected on their grade range and mineralogical properties. • All drill assays are required to conform to the procedural QAQC guidelines as well as routine laboratory QAQC guidelines. • All QAQC controls and measures were routinely reviewed and reported on a monthly, quarterly and |

| 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. • Significant intersections reported from the Lachlan Copper-Gold Project are based on greater than 1% Cu and may include up to 3m of internal dilution, with a minimum composite grade of 1% Cu. • Cu grades used for calculating significant intersections are uncut. |

| • All results reported in this document have been derived from 1m split samples. • Length weighted intercepts are reported for mineralised intersections. |

| 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 5: 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 Lachlan Copper-Gold Project are reported as down hole intersections. True widths of reported mineralisation are not known at this time. (refer Table 6: Drill hole assay intersections for the Lachlan Cu-Au Project). |

| 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 from the Springfield Project is not considered as material to this document at this stage. Other data collection will be reviewed and reported when considered material. • This report includes results from recent Geophysical Surveys from the Lachlan Project.
