LONG NICKEL MINE
Safety: No Lost Time Injuries (LTI's) for four successive quarters.
Production:
- 41,071t @ 4.50% Ni produced (IGO share 1,100 Ni t).
- In the March quarter, 1,187 Ni t were contained in ore mined from reserve blocks with nickel production 110% higher than reserve estimates.
- 810t @ 2.9% Ni mined from Victor South decline development north of June 2003 ore $\bullet$ resource boundary.
- When Victor South ramps up to full production of 8,000t/month of ore, annualised production is expected to result in IGO's share of annual nickel metal increasing by 70%.
Development:
Victor South:Decline development to access Shoots 1 and 2 continued during the quarter intersecting probable Shoot 2 nickel mineralisation north of previous resource outlines. Development is expected to intersect the high grade Shoot 1 mineralisation in the June quarter. A drill drive was completed to enable conversion of additional resources to reserves and to finalise the mine plan.
Exploration Results:
- Victor South: Drilling confirms probable northern extension of Shoots 1 (4.7m @ 2.2% Ni) and Shoot 2 (3.8m @ 3.8% Ni) north of the current resource and reserve boundary.

MINING OPERATION
LONG NICKEL MINE
160.100%
TARGETS: I) SAFELY PRODUCE \$60 MILLION CASH AFTER DEBT REPAYMENT AND TAX OVER 5 YEARS II) DOUBLE CURRENT MINING RESERVES TO +50,000 TONNES NICKEL METAL
The Long Nickel Mine, operated by IGO's wholly owned subsidiary Lightning Nickel Pty Ltd ("LN"), produced 1,848 Ni t (IGO share 1,100 Ni t) during the quarter.
The 4.50% head grade (budget 3.3%) continued to reflect:
- a higher proportion of massive sulphides from Long stopes, and
- high-grade ore from Gibb South (5.642 t @ 7.7% Ni) which is performing above expectations.
The higher than budgeted head grade also continues to reflect improved grade control and the discovery of new high grade positions outside June 2003 resource and reserve estimate boundaries. The geotechnically driven mining schedule is being adhered to and no high grading has taken place.
SAFETY
No Lost Time Incidents (LTI's) occurred during the quarter. Only one LTI has occurred since the mine re-opened in October 2002.
PRODUCTION
Production during the quarter comprised 41,071 t @ 4.50% Ni consisting of the following:

DEVELOPMENT
Victor South
A total of 2.500 metres of Jumbo development is planned to fully develop this high-grade position. To the end of this quarter 865.9 metres have been completed. Mineable widths of presumed Shoot 2 nickel ore (massive 19.7% and matrix 5.5% Ni grab were samples) were intersected 40m north of the June 2003 resource and reserve boundary by the development (Figure 1). Development is on track to intersect the high grade Shoot 1 mineralisation in the June quarter. A drill drive has been completed over Victor South enabling further reserve definition drilling and testing for new resources to the north, south and beneath the current resource envelope. This drilling will also serve to finalise the mine plan.
Underhand Cut and Fill Remnant Pillar Extraction
The Company's Research and Development program to extract high-grade pillars beneath tailings-filled stopes is progressing well with the successful excavation and support of uncemented mine tailings above high grade pillars in a localised area. Test work has indicated a number of pillars are in an un-stressed condition and therefore can be extracted by traditional methods once open stopes in the vicinity of the pillars are filled.
DEVELOPMENT CAPITALISATION
Currently only the Gibb South incline and Victor South decline are being capitalised. All other development in the mine is being expensed in the quarter in which the work is undertaken to maintain IGO's conservative balance sheet. These expensed development costs are included in the production costs.
GROUND CONDITIONS AND SEISMICITY
Rock bolting, cable bolting, meshing and shotcreting continue to provide excellent ground support. The mining team are currently evaluating the purchase of a concrete batching plant to reduce mining costs. Mine induced seismic events continue to be recorded at a much lower frequency than when Long was being mined at higher rates by the previous operator.
RESERVES
A large geophysical and drilling program aimed at increasing the company's Long Nickel Mine nickel reserves to 50,000t of contained nickel metal commenced during the quarter. The program, which may take 12 months to complete, comprises:
- a systematic geophysical survey testing the Long. Gibb South and Victor South ore positions using the company's proprietary electromagnetic (EM) Torch to locate and define new massive and matrix nickel sulphides up to 100m from existing mine workings;
- +10,000 metre diamond a. drilling program using up to 5 underground drill rigs on 2 shifts converting existing resources to reserves and testing new targets defined by the EM Torch and geological studies; and
- down-hole transient EM surveys.
It is anticipated that approximately 22,000 of the nickel metal tonnes defined in the June 2003 reserves will remain unmined by the end of the current financial year. An additional 28,000 t will be targeted from:
- existing mine resources outside reserves (60.000 Ni t at June 2003):
- mine pillars outside reserves and resources (27,200 Ni t at June 2003); and
- new near-mine discoveries which can be existina cheaply mined usina underground infrastructure.
New ore blocks outside ore reserves continue to be defined in the upper and lower levels of the mine. To date $31.767t$ @ 4.6% Ni has been mined outside reserve blocks this financial vear. predominantly from previously unknown remobilised massive nickel sulphide hanging wall and footwall surfaces predominantly on the 15 and 16 levels. More importantly, these new surfaces are open in many directions which should add further to the reserve base.
Gibb South
To date, a total of 19,143t @ 7.1% Ni (1,365 Ni t) has been mined from Gibb South (June 2003 reserve 28,000t @ 3.7% Ni - 1,000 Ni t). Gibb South's ore grade averages 7.1%
Ni, significantly higher than the reserve arade. Mining has defined additional high grade nickel ore outside the June 2003 ore reserve boundary. TEM surveys have located new conductors south of the current ore reserve block which the company plans to develop.
Victor South
Victor South contains 5,900 Ni t in reserve and an additional 14,900 Ni t in resources. Ore reserve definition drillina has commenced, using the drill drive over the ore body, to convert existing resources to reserves by increasing drill density. Drilling will also test for extensions to the south (open) and around the open 5.35m $@$ 13.4% Ni drillhole intercept in Shoot 3 (not in the mining schedule).
LONG EXPLORATION
Victor South
Drilling to test for Shoot 1 and 2 extensions to the north of the current Victor South resource outlines has been successful, possibly extending both shoots 40m north (Figure 2). Significant results are detailed in Table 1
11 - 12 Level Exploration
Re-interpretation of the felsic intrusive model has lead to the discovery of more high grade nickel sulphides above the 11 level in an area previously thought to be stoped out by intrusives (Figure 1). Significant results are detailed in Table 2
GEOPHYSICS
Numerous EM anomalies outside current reserves and resources have now been defined in the mine by the EM Torch and down-hole geophysical surveys.
Surveys on the 15 and 16 levels are proving to be very productive, with large anomalies defined outside existing resource and reserve blocks (Figure 3).

Long South
Drilling at the Long South Prospect (Figure 4) has recommenced after the completion of down-hole EM surveys which defined a number of off hole anomalies (Figure 5). These anomalies could be due to massive/matrix nickel sulphides or barren sulphidic sediments.
LSU001 W1 is currently in progress to test the prospective basalt-ultramafic contact in the vicinity of these conductors situated 130m south of the KD 6067B W7 intercept (3.6m @ 3.3% Ni including 0.29m @ 14.6%) Ni). The hole is currently being reamed out to 320m where a wedge will be set followed by an estimated 250m of coring to intersect the contact at 570m.

REGIONAL NICKEL EXPLORATION
Evaluation of the De Beers and WMC chromite chemistry databases along with in-house targeting identified a large number of quality nickel targets during the March quarter. Preliminary evaluation of targets on unpegged ground resulted in the acquisition of tenements to cover several distinct prospective areas $(Fiquare 6(b)).$
During April IGO negotiated joint venture agreements with Cullen Resources Limited at Irwin Bore and Mt Tate, and South Boulder Mines Ltd on the Duketon project.
CULLEN JOINT VENTURE
(IGO earning 65 - 70%)
IGO has entered into an agreement with Cullen Resources Limited (Cullen) to explore for nickel on its 90% owned Irwin Bore and 100% owned Mt Tate (including New Taffy Well) projects. The two project areas adjoin the Cullen-WMC Resources Ltd Gunbarrel Joint Venture where work by WMC to date has discovered significant massive nickel sulphides at the AK47 prospect. The Irwin Bore and Mt Tate projects cover strike extensions to the prospective ultramafic stratigraphy at AK47.
Under the agreement IGO can earn a 65% interest in the nickel and base metal rights at Irwin Bore by spending \$1.5m over four years. Independence can earn a 70% interest in the nickel and base metal rights at Mt Tate by spending \$1.0m over four years. IGO has a minimum first year commitment of \$180,000 at Irwin Bore and \$50,000 at Mt Tate.
Once IGO has earned its respective interest in the projects, Cullen can contribute to exploration or dilute to 15% free carried to decision to mine at Irwin Bore and a 20% free carried to decision to mine over the Mt Tate project. At decision to mine Cullen has the option to convert its interest to a 1% (Irwin Bore) or 1-1.5% net smelter return royalty (Mt Tate).
The remaining 10% of the Irwin Bore project is held by the Revesco Group Ltd. This interest is free carried to completion of a pre-feasibility study at which point it can be converted to a 1% net smelter royalty.
DUKETON NICKEL JOINT VENTURE
(IGO earning 70%)
IGO has entered into an agreement with South Boulder Mines Ltd to earn 70% of the nickel metal rights on tenements held by South Boulder in the Duketon greenstone belt.
The Duketon belt is considered highly prospective for nickel sulphide deposits and has seen little post-boom nickel exploration. It is believed the extensive transported cover in the belt would have significantly hindered previous explorers, and in-house modern technology held by IGO will give the joint venture an advantage in this terrain.
IGO is free to nominate tenements to be included in the joint venture from all existing and future tenements held by South Boulder in the defined area. IGO must spend a minimum of \$0.4 million on nickel exploration on the nominated tenements and free carry South Boulder at 30% to completion of a bankable feasibility study. South Boulder is free to dilute to 5% at which point its interest converts to a 5% net profit share rovalty.
DE BEERS JOINT VENTURE
• Chromite Targeting
First pass screening of the De Beers chromite chemistry database has identified a significant number of quality nickel targets. Tenement
acquisition by the JV commenced with the pegging of a high priority target (Mt Ross - see Figure 6(b)) on open ground. Reconnaissance evaluation of this target has commenced.
WMC DIAMOND DATABASE PROJECTS
• Chromite Targeting
Ongoing evaluation of the database identified three encouraging targets on unpegged ground. (Moorarie, Trillbar and Newdegate - Figure Exploration license applications have $6(b)$ ). been lodged to secure tenure over these targets. Reconnaissance evaluation of the targets is expected to commence during the June quarter.
MUSGRAVE JOINT VENTURE
• De Rose Hill
A ground EM survey over a third geochemical target was delayed due to heavy rains. This program is now scheduled for April with drill testing of geochemical and geophysical targets expected to be completed during the June quarter.
REGIONAL GOLD EXPLORATION
Ongoing regional targeting by IGO over recent vears has established an extensive portfolio of grass roots gold exploration properties. In total seventeen project target areas have been identified and secured under tenure
Most of these targets are based on gold geochemical anomalies generated through surface $\alpha$ r subsurface reconnaissance In nearly all cases these geochemistry. anomalies have been defined in new areas away from historic gold occurrences where soil cover has hindered previous prospectors and explorers.
Phase one drill testing of these targets at areas such as Goldsworthy and Benari during the March quarter was successful in returning encouraging bedrock gold results. $As$ tenements progress through the grant and native title process it is expected that the rate at which targets advance to the drill testing stage will start to increase.
100% IGO
• Wackilina
A ground magnetic geophysical survey was completed over the main target area at Wackilina during the March quarter. Processing of the data highlighted a zone of elevated magnetic response near the inferred centre of the i interpreted high-level, shallow-water. volcanic complex. RC drilling will be completed to test the magnetic target following the completion of aboriginal heritage surveys scheduled for April.
WMC DIAMOND DATABASE PROJECTS
Benari
A first pass RAB drilling program to test five gold in soil (auger) anomalies and two high magnetic targets was completed during January. This drilling identified two target areas where further infill RAB drilling was justified. These targets were based on bedrock gold intersections up to 4m @ 0.78 g/t Au (4m composites) and additional infill auger geochemical sampling. Results from the latest round of drilling are yet to be received.
Castle Creek
During the March quarter, Sipa Resources withdrew from the Castle Creek Joint Venture. The limited work undertaken by Sipa was based on conceptual base metal targets in the east of the project area. No work was completed by Sipa over the main gold target identified by IGO in the north west of the project area. Reconnaissance stream sampling over the main gold target area is scheduled for June.
Tropicana West
A detailed airborne magnetic survey scheduled for completion during the March quarter was delayed due to inclement weather.
New Projects
Exploration licences were applied for to cover the Nepean East and Adelaide Dam gold targets (Figure $6(a)$ ).
ANGLOGOLD TROPICANA EAST JOINT VENTURE (ANGLOGOLD AUSTRALIA MANAGER EARNING 70%)
Infill and extension RAB drilling commenced at Tropicana East during the March quarter. As part of the current program 100 holes for a total of 4503m of drilling were completed by AngloGold Australia, assay results are yet to be received
The drilling intercepted encouraging silica, sercite. pyrite alteration similar $t_{\Omega}$ that associated with previously identified aold mineralisation at Tropicana East and mapped by previous IP geophysical surveys. To date this zone of alteration has been defined over 5km and is open along strike in both directions (Figure 7).
A total of 703 auger geochemical samples were collected to test an area of extensive sand cover approximately $100 \text{km}^2$ in size. This area is to the north east along strike from the mineralised trend identified to date at Tropicana.
Regional surface geochemical sampling also commenced over parts of the extensive Tropicana East project area during the March quarter.

Figure 7: Tropicana East JV plan showing new alteration zones in relation to previous gold drill intercepts.
GOLDSWORTHY JOINT VENTURE
(IGO MANAGER EARNING 80%)
Results for the first round of wide spaced air core drilling at Goldsworthy outlined gold anomalism from four of the five traverses. The first pass aircore drilling tested a series of covered geophysical targets along the major. regionally mineralised Mallina Shear Zone within E45/2380 and E45/2285.
Follow up air core drilling was completed during January to test the geochemically blind targets. A total of 29 holes for 1443m were drilled to infill previous drilling down to a 50m section spacing over the four anomalous targets. Highly encouraging results including intercepts of greater than 1g/t Au over 1m down hole were returned from single drill traverses over two targets approximately 8km apart (Figure 8). Host lithologies include highly sheared Archaean metasediments. tourmalinite, lavered dolerite/gabbro. felsic intrusives. felsic metasediments and granitoid.
Further air core drilling, ground EM and magnetic geophysical surveys will commence to test the mineralization following completion of aboriginal heritage clearance programs scheduled for the end of April.
