In FY2015, IGO had record Revenue and Net Cash Flows from Operating Activities of $498.6 million (FY2014: $399.1 million) and $201.7 million (FY2014: $127.4 million) respectively. Unaudited Profit after tax for the June 2015 Quarter of $7.5 million was lower than the March 2015 Quarter result of $19.8 million. This was driven primarily by unfavourable Underlying EBITDA[1] variance ($38.0 million against $53.3 million in the March 2015 Quarter). Significant differences between the two quarters include:
1 Includes Other Income of $3.3M
2 Underlying EBITDA is a non-IFRS measure and comprises net profit or loss after tax, adjusted to exclude tax expense, finance costs, interest income, asset impairments, depreciation and amortisation.
3 Free Cashflow comprises Net Cash Flow from Operating Activities and Net Cashflow from Investing Activities.

-
3,200wmt of copper concentrate sold in the June 2015 Quarter from the Jaguar Operations relative to 7,800wmt in the March 2015 Quarter. Although higher volumes of zinc concentrate were sold in the March 2015 Quarter, profitability at Jaguar is sensitive to and dependent on the sale of copper and silver by-products. Furthermore, Jaguar’s June 2015 Quarter was negatively impacted by $3.0 million revenue adjustments arising from previous quarter’s sales. These adjustments related to both quotational period price adjustments, and adjustments to final grade assays. Consequently, Underlying EBITDA for the Jaguar Operations for the June 2015 Quarter was $4.2 million against $15.0 million in the March 2015 quarter;
-
Long Operation’s Underlying EBITDA fell 19% in the June 2015 Quarter to $11.9 million, due primarily to 15% lower payable nickel of 1,400 tonnes;
-
The June 2015 Quarter also saw an increase in Exploration and project acquisition expenses of $3.9 million and $2.3 million respectively. These increases were partially offset by unrealised favourable movements in the value of gold hedging of $3.7 million;
-
Tropicana’s Underlying EBITDA was $34.0 million for the June 2015 Quarter, which was consistent with the March 2015 Quarter, notwithstanding 5% lower gold sales for the June 2015 Quarter.
ACQUISITION OF SIRIUS (NOVA PROJECT)
Transaction
On 25 May 2015, IGO and Sirius announced the execution of a binding Scheme Implementation Deed under which IGO will acquire all the issued capital of Sirius by way of an Acquisition Scheme of Arrangement (the “Acquisition Scheme”). Under the Acquisition Scheme, Sirius shareholders will receive 0.66 IGO shares and 52 cents cash for each Sirius share. Sirius shareholders will also participate pro-rata in the demerger of the Polar Bear and Scandinavian exploration assets.
The transaction will create a leading diversified Australian mining company with a strong portfolio of highmargin/ long-life mining assets, across a range of base and precious metals. The combination of the two companies has a clear strategic rationale and will generate significant value for the shareholders of both companies. The acquisition will bring the world-class Nova Project into the IGO portfolio.
The Boards of both IGO and Sirius have unanimously recommended that all Sirius shareholders vote in favour of the Acquisition Scheme. Sirius’ major shareholder, Mr Mark Creasy, has also advised that, in the absence of superior proposal, he intends to vote in favour of the transaction.
The transaction remains on track with Sirius shareholders expected to approve the scheme in early September 2015 and IGO expects to complete the issue of the Share Scheme consideration in September 2015. For further detail on the transaction please refer to the ASX announcement dated 25 May 2015 titled “Independence to Acquire Sirius”.
Financing
IGO has entered into a syndicated facility agreement (“Agreement”) with National Australia Bank Limited, Australia and New Zealand Banking Group Limited and Commonwealth Bank of Australia Limited for a A$550M committed term finance facility on an unsecured basis. The Agreement comprises:
-
A five year $350M amortising term loan facility that will be used to refinance the existing Nova project finance facility, and provide funds for the continued development, construction and operation of the Nova Project; and
-
A five year $200M revolving loan facility that will be used to partially fund the payment of the cash component of the Acquisition Scheme and transaction costs, in addition to providing funding for general corporate purposes.
The Agreement provides IGO with significantly more operational and financial flexibility than alternative financing options, including retaining the existing Nova Project Finance Facility. The Agreement has been executed on favourable terms, within an accelerated time period with a strong and supportive bank group. This reflects the value of IGO’s diversified asset portfolio and its strong balance sheet, along with the low technical and commercial risk of the Nova Project. The Agreement is senior unsecured and cross guaranteed by the Australian IGO subsidiaries with no forward looking covenants. The competitive terms are expected to deliver substantial benefits to IGO over the life of the Agreement relative to the existing Nova Project Finance Facility.

TROPICANA JOINT VENTURE (TJV)
Joint Venture: IGO 30%, AngloGold Ashanti (AGA) 70% (Manager)
Safety
No LTIs were recorded in the June 2015 Quarter. The 12-month LTIFR [4] is currently 1.0.
Production
During the June 2015 Quarter, a total of 5.9M BCM’s[5] were mined and hauled ex-pit. This material is comprised of 2.9Mt of full grade ore (>0.6g/t), 0.3Mt of marginal ore (grading between 0.4 & 0.6g/t Au) and 11.3Mt of waste material. Ore was sourced from the Tropicana pit (1.7Mt) and the Havana pit (1.5Mt), with the average run-ofmine grade for full grade ore (>0.6g/t Au) being 1.97g/t Au for the period.
A total of 1.43Mt of ore at an average grade of 2.73g/t Au was milled during the June 2015 Quarter. Average metallurgical recovery was 90.3% for 116,600 ounces of gold produced.
Gold production and cash costs for the June 2015 Quarter were negatively impacted by lower processing plant throughput which was attributable to planned maintenance work. Key work on major components of the processing plant was completed, including a partial mill reline and the first change of the High Pressure Grinding Rolls. Roll life and mill liner life have been significantly better than expectations.
Attributable Production
IGO’s attributable gold production during the June 2015 Quarter was 34,980 ounces. During the June 2015 Quarter, IGO’s attributable share of gold refined and sold was 38,910 ounces. IGO’s attributable average cash costs for the June 2015 Quarter were $648/oz Au produced and all-in sustaining costs (AISC) of $817/oz Au sold. Please refer to Table 1 in Appendix 1 for further details.
Optimisation
The TJV partners plan to focus on optimising mill throughput rates. A mill optimisation study is underway to identify opportunities to increase throughput from nameplate capacity of 5.8 Mtpa to partially offset the planned decline in grade. Additional throughput could be achieved with modest capital investment.
A systematic replacement and upgrade program is underway on conveyors, feeders and rollers in the processing plant that in the past have caused unplanned downtime.
Tropicana-Havana Brownfields Exploration
During the June 2015 Quarter, drilling continued in the immediate vicinity of the Tropicana Gold Mine, with holes targeting at Havana North, Tropicana Extensions and Havana South/Crouching Tiger. A total of 3,870m of reverse circulation (RC) and 8,027m of diamond (DDH) drilling were completed. Better results include 12m @ 1.79g/t Au and 5m @ 5.25g/t Au at Havana North, 8m @ 3.48g/t Au at Crouching Tiger and 19m @ 1.19g/t in the Tropicana Extensions area. All significant intercepts are provided in Table 2 in Appendix 2.
Regional Exploration
Drilling during the June 2015 Quarter targeted the Madras, Masala and several regional prospects located between 25km and 40km south of the Tropicana Gold Mine. A total of 10,907m of aircore (AC), 4,331m of RC and 861m of diamond drilling (DDH) were completed. Better results from the Madras RC and diamond drilling include 18m @ 1.52g/t Au in RC and 10.4m @1.71g/t Au and 4m @ 2.05g/t Au in the same diamond hole. All significant intercepts are provided in Table 2 in Appendix 2.
Gas pipeline project update
Construction of the 292km long gas pipeline remains on target to be completed by the end of 2015 with first delivery of gas to Tropicana scheduled for early 2016. The pipeline and associated infrastructure is being constructed by APA Group which has also signed long term gas transportation agreements to deliver natural gas to Tropicana.

LONG OPERATION (Ni) – IGO 100%
Safety
No LTIs were recorded in the June 2015 Quarter. The 12-month LTIFR[6] is currently 3.1.
Production
Production was 67,958 tonnes of ore mined at 3.44% Ni for 2,338 tonnes of contained nickel. A full breakdown of production statistics is provided in Tables 3 and 4 in Appendix 3.
Nickel grades were impacted by lower grade stopes from Long, McLeay and Victor South which diluted strong grades from Moran.
Nickel was produced at a cash cost of $4.50 per payable pound of nickel inclusive of royalties and net of copper by-product credits (June 2014 Quarter: $4.11/lb Ni payable).
Development
A total of 620m was advanced by jumbo development during the June 2015 Quarter, of which 222m was booked as capital development and 398m as operational. Capital development remains focused on the development of drilling positions to target drilling for the previously announced McLeay South and Moran South mineralisation.
Near Mine Exploration
Near mine exploration drilling continued at the Moran South and McLeay target areas with 13 underground diamond drill holes for 2,060m completed, during the June 2015 Quarter. See Tables 5 and 6 in Appendix 4 for further details.
Moran South Development
During the June 2015 Quarter, total mine development for the Moran South drill drive was 222m. This includes 53m advance in the drill drive face and 169m development of stockpiles and vent drive access to accommodate additional mine infrastructure to service the drill platform. Some 290m of development remains to complete the drill platform in preparation for drill testing of the Moran South mineralisation (see Figures 3 and 4 in Appendix 4).
Moran South
Two underground diamond drill rigs are currently in the Moran South drill drive and have commenced an infill drilling program consisting of 18 underground diamond drill holes for 3,220m. Drilling on 40m x 40m spacing will test a 320m down plunge and 60m wide zone. In the June 2015 Quarter, three drill holes, for 448m, were completed (see Table 5 in Appendix 4) with the best intercept reported in drill hole:
LSU-510 with 0.6m @ 10.7% Ni from 63.05m (0.5m True width).
The drill program will be completed in the September 2015 Quarter and further step out drilling is planned for the FY2016.
McLeay
Ten underground diamond drill holes for 1,547m were completed in the June 2015 Quarter. The infill diamond drill program designed to upgrade the McLeay resource classification is now complete. A zone of nickel mineralisation 100m down plunge, 60m wide and an average thickness of 1.7m was identified. A summary of the McLeay infill drill results is listed in Table 6 in Appendix 4.

JAGUAR OPERATION (Zn, Cu) – IGO 100%
Safety
No LTIs were recorded in the June 2015 Quarter. The 12-month LTIFR[7] is currently 3.3.
Production
During the June 2015 Quarter, mining delivered 118,240t of ore at 9.52% Zn, 1.40% Cu, 143g/t Ag & 0.7g/t Au to the ROM stockpile. The tonnage and grade of ore mined was consistent with plan.
Mill Production
Mill production was 124,591t of ore at an average grade of 9.29% Zn, 1.38% Cu, 140g/t Ag & 0.7g/t Au for 10,221t Zn and 1,449t Cu metal in concentrates. Further details of mill production in the June 2015 Quarter are set out in Table 7 in Appendix 5.
Payable zinc metal during the June 2015 Quarter was produced at an average cash cost of $0.59/lb of payable zinc, including royalties and net of by-product credits (June 2014 Quarter: $0.15/lb Zn payable). Higher than planned throughput and grades consistent with plan has resulted in better than planned metal production.
Concentrate
The mill produced 26,860t of concentrate during the June 2015 Quarter, of which 21,294t was zinc concentrate and 5,566t was copper concentrate (See Table 7 in Appendix 5). Nominally, 31,000 wet metric tonnes (wmt) of Zinc concentrate and 3,200wmt of copper concentrate was sold during the June 2015 Quarter.
Mine Development
A total of 1,182m of advance occurred during the June 2015 Quarter, of which 804m was capitalised, with the remainder accounted for in operating costs.

Ongoing drilling at Triumph is designed to test both up-and down-plunge extents of mineralisation and infill the high-grade core on a nominal 80m x 40m spacing. A full listing of drilling and significant intercepts is provided in Tables 8 and 9 in Appendix 6 of this report.
EXPLORATION AND DEVELOPMENT PROJECTS
STOCKMAN BASE METALS PROJECT (IGO 100%)
Detailed permitting work for the Stockman project continued during the June 2015 Quarter.
DARLOT JV (IGO Manager and Earning 70% - 80%)
Late in the June 2015 Quarter, an AC program comprising of 106 holes for 4,968m tested the Jarrah Well and 20ft prospects. Wide-spaced AC drilling on these prospects in 2014 outlined anomalous base metals and VMS pathfinder geochemical responses associated with black shale horizons. The current program is designed to infill and extend previous drilling to generate targets for follow-up deeper RC and diamond drill testing. Assay results had not been received at end of the June 2015 Quarter.
LAKE MACKAY GOLD/BASE METALS PROJECT (IGO Manager and Option to earn 70%)
Late in the June 2015 Quarter, an AC program comprising approximately 100 holes (8,000m) commenced in the southern part of the project testing six gold and multi-element surface sample anomalies located on EL24915 and one gold target (Windemere South) located on EL27780. No assay results had been received at the end of the June 2015 Quarter.
BRYAH BASIN JV (IGO Manager and Earning 70% - 80%)
AC drilling in the Neptune area during the June 2015 Quarter confirmed a 2.5km long strike-parallel zone of multi-element VMS pathfinder anomalism at the prospective basal contact of the Narracoota Formation with the underlying Karalundi Formation. These zones of geochemical anomalism are semi-coincident with several linear electromagnetic (EM) conductors returned from moving-loop EM (MLEM) surveys.
In June 2015, the Company commenced a drilling program to test Neptune at depth. The program comprises five RC holes and three RC/diamond tail holes on five sections, nominally 500m apart, testing 2km of strike of the prospective zone. All holes will be tested with downhole EM upon completion. The diamond drilling component of this program is being funded in part by the WA Government Exploration Incentive Scheme Cofunded Drilling Initiative. Drilling is still in progress and no assay results have been received.
SALT CREEK JV (IGO 30%, EARNING TO 70%) (SCJV)
The SCJV comprises a northern and southern group of tenements on the eastern flank of the Tropicana JV that are being explored for magmatic Ni-Cu mineralisation. The southern tenement group contains a number of discrete magnetic features potentially representing mafic/ultramafic intrusions. These have been tested by a program of MLEM surveys which has identified a conductor. This conductor will be followed-up with a FixedLoop EM (FLEM) survey to determine if a drill test is warranted.
The northern group covers a broad area exhibiting a complex magnetic signature, interpreted to represent multiple magmatic intrusive events. Detailed gravity surveying followed by broad-scale AC drilling is being undertaken to define geochemical signatures indicative of fertile rock types. During the June 2015 Quarter, the first phase of broad spaced AC drilling comprising of 240 holes (10,842m) was completed over an area of approximately 217km[2] of interpreted Salt Creek Complex. This work has identified three areas exhibiting anomalous nickel and copper geochemistry. These areas will be tested by closer-spaced AC drilling in the September 2015 Quarter.
BEACHCOMBER JOINT VENTURE (JV) (IGO 30%, EARNING TO 70%)
At the Maverick Prospect, a MLEM survey was completed over the peak of the Cu-Zn geochemical anomaly confirmed by AC drilling in the March 2015 Quarter. The survey detected four discrete EM conductors within close proximity to the anomalous host unit, however they are not consistent with a large massive sulphide mineralised system. IGO has subsequently withdrawn from the Beachcomber JV. The tenements revert back to the Tropicana JV.

A. JORC CODE, 2012 EDITION – TABLE 1 – TROPICANA EXPLORATION RESULTS Q2 2015 SECTION 1 SAMPLING TECHNIQUES AND DATA
| Criteria | Commentary |
|---|---|
| Sampling techniques | Aircore (AC) samples were collected with a scoop from spoil piles placed on the ground as one metre samples. Sampling aimed to be as representative as possible by sampling through the entire spoil pile. Samples are collected as 4m composite samples or smaller composites where required to complete the hole. Samples weigh approximately 3kg in total. Anomalous intercepts >0.05g/t Au at early stage targets are resampled at 1m intervals and resubmitted for analysis. Reverse Circulation (RC) samples were collected as 1m samples at the rig using a cone splitter. Two samples at a variable split of approximately 1-in-8 were collected with the resultant samples each weighing about 2-3kg. Mineralised zones and zones of geological interest were submitted to the laboratory for assay as 1m samples. Unmineralised zones were submitted to the laboratory for assay as 2m composite samples. The 2m composite samples are split through a riffle splitter and submitted for analysis. Archive 1m samples of the entire hole are retained for future sampling and check work if required. Diamond core (NQ2 diameter) was sampled as half core over typical down-hole widths of 1m for mineralised intervals (minimum width 0.3m maximum width 1.3m as appropriate geologically). Sampling intervals are extended acrosslarger intervals (up to2m) as quarter-core throughunmineralisedzones. |
| Drilling techniques | All samples from AC drill holes were collected using standard 89mm (3.5”) diameter AC bits. RC drilling was collected using a face sampling hammer with a 127mm (5”) bit. Diamond core was NQ2 diameter (75.7mm hole diameter,50.5mm core diameter). Core was orientated usingthe Ace Core Tool TM. |
| Drill sample recovery | RC and AC sample recovery was based on visual estimates and generally good and recorded in the drill database. Wet samples were recorded in the database. Diamond corerecoveryismeasured andlogged across coreruns during the coremark-up process. |
| Due to the early stage of exploration, no quantitative measures were taken for sample recovery for the RC and AC samples. Diamond core recovery was generally good. Core was reassembled for mark-up and was measured, with metre marks and down-hole depths placed on the core. Depths were checked against driller’s core blocks and anydiscrepancies corrected after discussion with drillers. Core loss was recorded in thegeological log. |
|
| Thereisno obviousrelationship betweensamplerecovery and grade. | |
| Logging | Geological logging was completed using standard logging digital data entry software and the AGA geological logs and coding system. Data on rocktype, deformation, colour, structure, alteration, veining, mineralisation and degree of weathering were recorded. These samples have not been used for any Mineral Resource estimation, mining studies or metallurgical studies, but thelevelofdetail is sufficient to supportMineral Resource estimationandMining Studies. |
| Logging is both qualitative and semi-quantitative in nature. Alldrillcoreis photographed. |
|
| Each hole is logged and sampled in full. | |
| Sub-sampling techniques and sample preparation |
AC chips were sampled using a scoop and were generally dry, but some wet samples were collected. Samples were initially collected as 4m composites or smaller composites where required to complete the hole, with a 1m or 2m sample at the bottom of the collected to enable analysis of the freshest material. Intervals returning >0.05g/t Au at early stage targets were typically resampled from the cuttings pile with a scoop, on a 1m basis. RC samples were split at the rig using a cone splitter with one sample sent to Genalysis for fire assay and the other sample retained for future sampling if required. All diamond core has been cut into half or quarter core for sampling. All samples were submitted to Genalysis for lead collection fire assay for either gold only or gold, platinum and palladium analysis, and for four-acid analysis of 46 elements. Samples were oven dried at 105°C then jaw crushed to -10mm followed by a Boyd crush to a nominal -2mm. Samples were then pulverised in LM5 mills to a nominal 85% passing 75µm. Samples were analysed for gold using the Genalysis FA25/SAA technique, or for gold, platinum and palladium using the Genalysis FA25/MS technique. The FA25/SAA technique utilises a 25g lead collection fire assay with analysis by solvent extraction Atomic Absorption Spectrometry and the FA25/MS uses a 25g lead collection fire assay with analysis by Inductively Coupled Plasma Mass Spectrometry (ICP-MS). The fire assay method is considered a suitable assaying method for total Au determination. Multi-element analysis was completed using the Genalysis 4A/OM10 technique, which uses four-acid digestion with analysis of 46 elements by a combination of ICP-MS and Inductively CoupledPlasma Optical EmissionSpectroscopy (ICP-OES). |
| The samplepreparation technique is appropriate and is standard industry practice forgold exploration. | |
| AC composite samples returning >0.05g/t Au are typically resampled at 1m intervals (resplit samples) and assayed as above. Where 1m resplits have been taken, these results are reported in preference to the 4m composite samples assays. No quality control procedures were adopted to prove sample representivity. No field duplicate samples were taken for AC, RC or diamond samples. The drilling completed at Tropicana Q4 was for exploration only and is not used in resource estimation, where more rigorous QAQC is employed. Sample sizeis appropriateforthe targetedmineralisationstyles. |
|
| Quality of assay data and laboratory tests |
The25gfire assay technique usedis a totalextraction methodforgold. |
| No geophysical or XRF results are reported. | |
| Quality control procedures included insertion of certified standards (approximately 1 in 25), and blanks (1 in each hole). No external laboratory checks have been completed and therefore precision levels have not been established. Review of the analyses of the certified standards do not indicate any accuracy issues. |

| Verification of sampling and assaying |
No checks were made or required for this level of exploration. |
| No twin holes have been completed. | |
| Primary data are collected in Field Marshall files on portable computers. Data are imported directly to the database using software with built in validation rules. Assay data are imported directly from digital assay files supplied from the laboratory and are merged in the database with sample information. Data are uploaded to a master SQL database stored in Perth, which is backed up daily. |
|
| There has been no adjustment to assay data. | |
| Location of data points | Hole collars have been surveyed using a hand held GPS. Downhole surveys were completed at 30m intervals in RC and diamond holes utilising a Reflex Ez-Trac instrument. The dip and azimuth from the collar setupwere used for AC holes. |
| Drill holelocationdatawere capturedintheMGA94grid system,Zone 51. | |
| There is no topographical control. Holes are assigned a collar RL from a regional digital elevation model. As these holes do not form part of a resource model, it is not necessary for accurate topographic control. |

| Sample security | Samples are sealed in calico bags, which are in turn placed in large poly-weave bulk-bags for transport. Filled poly-weave bulk-bags are secured on wooden crates and transported directly via road freight to the laboratory with a corresponding submission form and consignment note. Genalysis checks the samples received against the submission form and notifies AGA of any missing or additional samples. Once Genalysis has completed the assaying, the pulp packets, pulp residues and coarse rejects are held in their secure warehouse. On request, the pulp packets are returned to the AGA warehouse on securepallets where theyare documented for longterm storage and retrieval. |

| SECTION2 REPORTING OFEXPLORATIONRESULTS | |
| Criteria | Commentary |
| Mineral tenement and land tenure status |
Tropicana is a joint venture between AngloGold Ashanti Australia Limited (AGA) and Independence Group NL (IGO) (AGA:IGO, 70:30) AGA is the manager of the JV. Significant results are from several tenements within 90km of the Tropicana Mine. There are no known heritage or environmental impediments over the leases where significant results were received. |
| The tenure is secure at the time of reporting. No known impediments exist to operate in the area. | |
| Exploration done by other parties |
The intercepts reported are from drill programs designed to follow up mineralisation discovered by AGA during regional exploration since the JV inception in 2002. The area had previously been essentially unexplored untilthe JVdiscovered goldmineralisationatTropicanain 2005. |
| Geology | The host rocks are predominantly gneisses interpreted to be in the same package of rocks as the Tropicana andHavana gold deposits.Controls on mineralisationare currently unknown. |
| Drill hole Information | The easting, northing, approximate RL, dip, azimuth, hole depth, down hole length and intercept depth of all intercepts >2m @ 0.5g/t Au are given in tables in the text of the report. Details for holes which returned <2m @ 0.5g/t Au are not tabulated as they are not significant. |
| The absence of the details of the holes with <2m @ 0.5g/t Au is not considered material given the early stage of exploration at these prospects. The exploration is at an early stage and no continuity between mineralised interceptsisimplied. |
|
| Data aggregation methods |
Intercepts were calculated using length-weighting above a 0.5g/t Au cut off with a minimum downhole length of 2m and maximum of 2m of internal dilution. No top-cuts have been applied. |
| Relationship between mineralisation widths and intercept lengths |
Intercepts reported are downhole lengths, true widths are unknown. |
| Diagrams | A plan view of the locations of the significant intercepts is provided. Due to the early stage of exploration, sectionshavenot been included. |
| Balanced reporting | All intercepts >2m @ 0.5g/t Au have been provided. Holes with intercepts <2m @ 0.5g/t Au have not been reported due to their largenumber. |
| Other substantive exploration data |
There are no other exploration data to report that are considered material. |
| Further work | Follow up drilling is planned in the coming quarters. |

SECTION 1 SAMPLING TECHNIQUES AND DATA
| Criteria | Commentary |
|---|---|
| Sampling techniques | Underground diamond drill core consisted of HQ, LTK-60 and BQTK drill core diameters. Sampling was undertaken by ½ coring to logged geological intervals using an automatic core saw. Maximum sample length is 1.1m and minimum sample length was 0.1m for all core sizes. Sample lengths did not cross geological intervals. Core was cut to give sample weight of approximately 3.2kg. All geological contacts between the footwall basalt and hanging wall ultramafics, with or without the presence of sulphides, were sampled. Sample intervals extend at least 5m beyond the sulphide zone (greater than 1% nickel grade) within the footwall and hanging wall geological contact positions. Samples were crushed and pulverised (total prep) to produce sub-samples of 400mg for analysis by mixed four acid digest, followed by ICP-OES analysis. Down hole electromagnetic geophysical surveys have been undertaken to assist in targeting of massive sulphide horizons. Densities were determined using Archimedes water immersion technique. |
| Drilling techniques | Diamond drill core consisted of HQ (core diameter 63.5mm) holes are drilled where bad ground is expected. Drilling also consisted of LTK-60 (core diameter 43.9mm), BQTK core sizes (core diameter 40.7mm) and Drillcorewere un-orientated. |
| Drill sample recovery | Diamond core was logged and recorded in the database. Intervals of core loss are logged as geological units with a code of ‘CLOSS’. Intervals of partial core recovery are rare, but are noted in comments for both the sample and geology logs. Overall recoveries are >95% and there are no core loss issues or significant sample recovery problems. Intervals of core loss were not included in the sample intervals. All recent drilling is completed using underground diamond drill holes with high (>95%) core recovery. Diamond core was reconstructed into continuous runs, where possible, and each interval identified on the core and the depths checked against the depth given on the core blocks. Rod counts are marked on additional core blocks routinely completed by the drill contractor. Core losses are marked on additional core blocks marking the start of core loss and end of core loss intervals, by the drill crew. HQ drillcorewas usedinareas ofbad ground to assistincorerecovery. |
| Logging | Geotechnical logging was captured on diamond drill holes for recovery, RQD, and number of fractures (per interval). The information is captured in the main database. Logging of drill samples recorded lithology, mineralogy, mineralisation, veins, alteration minerals, contact type. Recent core samples were photographed wet and the images stored in the main database. The drillsampleswerelogged qualitativelyin full forallsamples. |
| Sub-sampling techniques and sample preparation |
All samples were cut in ½ using an automatic core saw cutter. All core samples were collected from the same side of the core. Extremely broken core is sampled by visually picking a representative sample consisting of half of the rock fragments. The core samples were totally crushed in a jaw crusher to a nominal particle size of 6mm then fine crushed in a Boyd crusher to a nominal size of 2mm. A sub-sample of approximately 750g is split out via a rotary divider (the rotary divider is adjustable so that consistent-sized splits can be taken for pulverising, regardless of original sample weights). The sample is then pulverised in a ring mill. A sub-sample of 100g is taken from the pulverised, homogenised sub-sample; this sub-sample is retained as the ‘pulp’. An assay sample of 400mg is taken from the pulp for mixed four acid digest and then ICP-AES analysis. Sample preparation checks for grain size were carried out by the contract laboratories as part of its internal checks to ensure the grind size of 90% passing 75 microns. Greater than 90% of all sizing tests met acceptable limits. Field QC is through the use of certified reference material as assay standards inserted at irregular intervals and blank core samples inserted after massive sulphide mineralisation and at irregular intervals. The insertion rate is 1 in 10 blank samples and 1 in 20 standard samples. Results of standards and blanks from each batch are scrutinised at the time they are reported, and compared with expected values. Variation outside two standard deviations of the expected result is reported to the lab for checking, and re-assaying if required. In-house QAQC reports are produced quarterly and yearly to examine variability in standards and blanks performance and reliability. The ½ core were sampled at 0.1m to 1.1m sample intervals was considered to be appropriate to correctly represent the sulphide mineralisation based on the style of dominantly massive and matrix sulphides, the thickness and consistency of the intersections, the sample methodology and percent value assay range for theprimaryelements. |
| Quality of assay data and laboratory tests |
The analytical techniques used a 400mg sub sample digested in mixed 4 acid digest (Nitric Acid, Perchloric Acid, Hydrochloric Acid and Hydrofluoric Acid). The digest commences with the samples at room temperature and after thirty minutes the beakers are transferred to a hotplate which heats the digest solution to 200°C. The digest solution is reduced until the solution is reduced to a dry, solid, state. This process takes approximately four hours. The dry, powdery, material which remains is soluble in Hydrochloric Acid and is ready for the next stage. The beaker is then removed from the hot plate and Hydrochloric Acid is added. The beaker is then returned to a hotplate, this time operating at 100°C. This “leach back” stage ensures all solids are dissolved back into solution. The beaker is then removed from the hotplate and allowed to cool. De-iodised water is then added to the beaker to bring the volume up of the solution up to a standard 18ml and the solution is then transferred to a test tube, where the volume is checked again and if necessary adjusted. This solution is vigorously agitated, so that solution is fully homogenised. This “Primary Digest Liquor solution” is diluted on a 1:1 basis. Included in the diluent are two rare elements, which are used as “internal standards” - Yttrium (Y) and Ytterbium (Yb). The ICP-OES analysis is run for either four (production drilling) or nine elements (exploration drilling). The fourelement suitewithdetection limitsis: Ni(10ppm), Cu (10ppm),As (10ppm), S (100ppm).

No geophysical tool was used to determine element concentrations. Sample preparation checks for grain size were carried out by the contract laboratories as part of its internal checks to ensure the crush size of 90% passing 2mm and grind size of 90% passing 75 microns. Greater than 90% of all sizing tests met acceptable limits. The performance of the blanks and standard samples submitted to the laboratory returned acceptable values. No umpirelabswere used. No precisioncheckshave been implemented. |

| Verification of sampling and assaying |
Due to the high visibility of mineralisation, significant intersections in diamond core were visually verified following lithological logging of core samples and after laboratory analysis, by IGO geologists. Core photos and visual checks from remaining half core samples were randomly checked. No drill holes were twinned. Primary data was collected on laptop computers using acquire interface. The information was transferred into the main drill hole acQuire Database version 4.4.1.2 with SQL2008 database server. There was no adjustment to assay data. Assay results are submitted from the laboratory via email in CSV and PDF files. Original Assay files are archived digitally in the company computer network. CSV files are imported into acQuire database through a database extractionprotocol. |
| Location of data points | The planned drill collar for underground diamond drill holes are laid out by marking the back-sight and fore- sight pins drilled in the walls of the mine development IGO Surveyor using a Viva TS15 Total Station Theodolite considered to be accurate to 0.002m. The collar position is later picked up locating the exact position of the drill hole. The collar coordinates are stored in a database. The recent planned drill collars for surface diamond drill holes were laid out using a Leica-RTK GPS by IGO surveyors. The collar position is later picked up locating the exact position of the drill hole. The collar coordinates are stored in a database. Down hole surveys were taken using an Electronic Reflex Ez-Trac down hole survey tool by the Diamond drilling contractors. Holes were down hole surveyed with multi-shot surveys (6m intervals) at the completion of the hole. Single-shot surveys were progressively taken as the hole was drilled to maintain planned drill direction at 15m, and 30m intervals. Stated accuracy of the Electronic Reflex Ez-Trac down hole survey tool is 0.35 degrees on azimuth and 0.25 degrees on Dip. All down hole surveys were stored in the database and de-surveyed as curvilinear projections down the drill hole trace. No significant survey problems were identified. The grid system is MGA_GDA94, Zone52. The resource is calculated in Local Grid (KNO-Grid). It is a non- linear projection of MGA co-ordinates. All collars are captured in Local Grid. North-South Local Grid is -1 degrees off Magnetic North declination. MGA co-ordinates are generated by automated scripts within the database. |
| Data spacing and distribution |
Diamond drill spacing for drill holes reported this quarter were variable, between 40m to 80m drill spacing along plunge and between 20m to 40m drill spacing down dip. Sample compositinghas not been applied to the drill core. |
| Orientation of data in relation to geological structure |
Orientation of mineralisation is interpreted to be similar to the McLeay and Moran ore bodies trending north- south and plunging shallowly to the south. Underground diamond drill holes collars are fanned off sections and drilled at near perpendicular up dip and downdip ofthemineralisation fromunderground drillplatforms. |
| Sample security | Core samples are stored on site and delivered by IGO personnel to ALS in Kalgoorlie which is transported and processed in ALS Perth Laboratory. Whilst in storage the samples are kept in a fenced and locked yard on site. ALS has a batch tracking system that allows IGO staff to track progress of batches of samples from delivery to submission of results. Half core is kept for reference is stored in a fenced and locked yard on site. Thelocationand photographs ofthe core samples are stored onaregularbasisinthemaindatabase. |
| Audits or reviews | The sampling techniques and data are collected and managed by IGO staff geologists familiar with the local rock-types and data collection process established over 14 years, with IGO and previously through WMC Resources The major rock-types of the area are visually distinct from each other in drill core, there are no major inconsistencies or errors in the logging of lithology or mineralised zones. The database is audited annually byIGO staff. |

| Mineral tenement and land tenure status |
Mineralisation intercepts reported this quarter are located on the tenements listed below: Listed below are tenement numbers and expiry dates. M15/1515 – expiry date 23/12/2025 M15/1763 – expiry date 05/10/2025 There are no Native Title Claims registered over the lease and no other known impediments. The mineralisation reported on M15/1515 which forms a part of a Joint Venture Agreement with St Ives GoldMining Co. PtyLtd (SIGM). |
| Exploration done by other parties |
Exploration was initially undertaken by WMC and eventually commissioned the Long Shaft and Victor decline mine development. This data is of high quality with most of the historic work is concentrated in areas thathave been mined out. |
| Geology | The mineralisation is typical Kambalda-style nickel deposits, consisting of narrow, steeply dipping, shallowly south-plunging, ribbon-like accumulations of massive and semi-massive (with minor disseminated) sulphides. The mineralisation is located at the base of Archaean komatiitic ultramafic flows at the contact with an underlying tholeiitic basalt unit. The massive sulphide is overlain by matrix then disseminated mineralisation, with the bulk of the nickel mineralisation being massive and matrix in nature. The host rocks and associated contacts have been subjected to lower amphibolite facies metamorphism,structural |

| Sampling techniques | All sampling is from the Triumph Prospect. | |
| Core samples are selected based on geological logging for appropriate representative samples of mineralisation. All identified mineralised zones are sampled along with appropriate buffers either side of mineralisation. |
||
| Diamond core size is HQ and NQ2. Core samples are ¼ and ½ core respectively to give sample weights under 3 kg. Sampling is on geological intervals (0.1 m to 1.2 m). Samples were crushed, dried and pulverised (total prep) to produce a sub sample for analysis by four acid digest with an ICP/OES, ICP/MS or fire assay FA/AAS (Au) finish. |
||
| Drilling techniques | Drilling is diamond core. Core diameter is HQ and NQ2 standard tube. Holes are generally drilled towards the footwall (approximately 66° magnetic and with a 60° dip from horizontal). Core is oriented using a Reflex ACT II tool - generally every 6 metres core run. |
|
| Drill sample recovery | Diamond cores are logged and recorded in the database. The measured lengths are compared with expected lengths to calculate recovery. There are no significant core loss or sample recovery issues. |
|
| There are no known sample bias issues related to recovery. | ||
| Logging | All drillholes were geologically logged for their full length. Geological logging included rocktype, deformation, structure, alteration, mineralisation, veining and RQD measurements. Geological logging is adequate for eventual resource estimation. |
|
| Core is photographed dry and wet for the full length. | ||
| All core is retained and permanently stored at the Company’s facilities. | ||
| Sub-sampling techniques and sample preparation |
Core was cut in ½ and ¼ depending on core size in the Company’s core farm. All samples were collected from the same side of the orientation line. |
|
| Samples were sent to Intertek Genalysis in Maddington, WA. The sample preparation method was to dry the core in ovens for at least 2 hrs (105°C), then jaw crush the samples to a nominal minus 10mm size then Boyd crush samples to a nominal minus 2mm. After crushing, the samples were pulverised in a mixer mill in a single stage mix and grind process (SSMG) to a nominal 85% passing 75 micron. Any samples that exceeded the 3kg mill limit were rotary split to 3kg prior to the pulverising stage. This technique is appropriateforbasemetals samples. |
||
| Coarse crush washes at the crusher stage and quartz washes at the pulverising stage have been implemented between every sample to combat sample carryover (contamination) during the sample preparation process. Sieve tests on 10% of the samples are performed to measure the fraction of pulp passing the 75 micron threshold. |
||
| Field duplicates were not inserted. | ||
| The sample sizes are considered to be appropriate for the base metal (VMS) mineralisation style. | ||
| Quality of assay data and laboratory tests |
The analytical techniques used a four acid digest multi-element suite with ICP/OES or ICP/MS finish (25 gram fire assay (FA/AA) for Au). The acids used are hydrofluoric, nitric, perchloric and hydrochloric acids, suitable for silica based samples. The method achieves total dissolution for most silicate minerals. Detection |

| limits for ICP-OES were Cu (10ppm), Zn (10ppm), Pb (50ppm), Ag (5ppm), Fe (0.01%). Detection limit for Au was 0.01ppm. The assay techniques used are considered appropriate for this type of mineralisation. |
|
| No geophysical methods were used in determining assay data. | |
| Field QC procedures involve the use of certified reference material as assay standards, along with blanks. For core the insertion rate of these varied between 1in 10 to 1 in 15, with an increased rate in mineralised zones. Standards indicate that individual laboratory batch jobs are within acceptable limits of 2 standard deviations from the accepted values. In addition grind size is also measured and is acceptable with plus 85% below 75 micron grind size. |
|
| Verification of sampling and assaying |
Drill core are checked for mineralised zones by senior site base geologists. Assay data are checked by senior IGO geologists. |
| There were no twinned holes drilled. | |
| Data are entered in the field electronically into Toughbook computers running the acQuire geological data entry system. Data are then transferred electronically to a dedicated Microsoft SQLServer database. Data are verified by routine internal software processes for data integrity and by manual checking by project and supervising geologists. |
|
| There are no adjustments to primary assay data. | |
| Location of data points | DD collars are located using RTK differential GPS for an accuracy of better than 0.3 m. |
| DD holes are downhole surveyed using a north seeking gyro survey tool. Data are captured every 5 metres. | |
| Grid system used is MGA_GDA94 Zone 51 and local JMG mine grid. | |
| Topographic control is from survey methods described above. | |
| Data spacing and distribution |
DD spacing is defined on geological criteria considered appropriate to define the scale of mineralisation in each prospect. Nominal drill spacing is 80-160 metres. Drill spacing is shown in the accompanying sections. |
| Data distribution is regarded as appropriate for the style of mineralisation sought, the stage of the exploration and the geological conditions encountered. |
|
| DD samples are selected on geological criteria and are not composited. | |
| Orientation of data in relation to geological structure |
DD holes are sited to intersect mineralisation perpendicular to orientation to minimise sample bias – holes are generally drilled towards the footwall at 66° magnetic and with a 60° dip from horizontal. |
| Sample security | Samples are stored on site then transported to the Perth laboratory via truck. Samples are stored in a locked yard at the laboratory and are electronically tracked. Pulps are stored in a locked shed at both the laboratory and when returned to site. |
| Audits or reviews | Sampling techniques and data QAQC is reviewed by Company based senior geologists. |
