HIGHLIGHTS
NORTH PERTH BASIN
-
Detailed mineralogical analysis has identified zircon concentrations up to 20% of the heavy minerals (HM) in the southern 2.5km of the Atlas deposit, coinciding with high grade HM zones averaging over 10%HM.
-
The overall Atlas HM grade has increased from 7.4%HM to 7.8%HM, with the Measured Resource grade increasing to 8.4%HM.
-
An intersection of 30m @ 7.7%HM from 27m, including 3m @ 34.7%HM at the north end of the Bidaminna deposit, indicating potential for a high grade core to what was previously thought to be a low grade deposit.
-
Acquisition of four Mining Leases from Iluka Resources containing an estimated total of 955,000t of HM and giving Image control of a 65km strike length of the Gingin Shoreline.
-
Resources from two of the Iluka tenements extend into Image’s adjacent resource areas; namely the Gingin South ML situated directly north of Image’s Gingin South resource and the elevated zircon Boonanarring ML showing a 7.7km ground magnetic extension to the north.
-
Infill drilling of the Gingin South deposit has confirmed continuity from visual HM estimates and is expected to result in estimation of a Measured Resource in the June quarter.
-
Drilling of targets in the Chandala area has identified a 2.4km-long mineralised zone at Chandala North and another potentially mineralised zone to the south.
COMMODITY PRICES
-
Further predictions by industry analysts of product price increases suggest zircon will reach US$2,000 per tonne by the end of 2011, two years ahead of Image’s previous forecasts.
-
The same analysts have also forecast significant ilmenite price increases with Sulphate Ilmenite predicted to reach US$180 - US$200 per tonne by year end.

The preliminary Atlas resource statement issued in the December 2010 quarter required additional mineralogical data to fully estimate the mineral assemblage. The results of QEMSCAN analyses of 47 mineralogy composites have now been received and these have been integrated with the existing composites, bringing the total mineralogical analyses to 81 composites spread at 400m line intervals along the strike of the deposit. This data was combined with the October resource model to produce an updated Measured and Indicated Resource for the Atlas deposit. The HM component of this resource estimate is tabulated at various cut-off grades in Table 1, with the mineral assemblages at the same cut-offs shown in Table 2.
The zircon content of the HM increases from north to south with a zone of +10% zircon evident in the southern 2.5km of the Atlas deposit. This distribution is shown in Figure 1, where the zircon content can be seen to vary up to 20% of the HM in the southern zone, correlating with increased HM content. Image expects that this increased grade will have significant economic implications for the exploitation of the deposit, potentially allowing the scheduling of high value ore at the start of mining.
The mineral assemblage results show that a small zone included in the October resource estimate contained significantly higher levels of iron-oxides than had been expected and therefore this zone has been excluded from the updated estimate, reducing the overall resource at a 2.5% HM cut-off by 1.4Mt to 10.8Mt and increasing the grade from 7.4%HM to 7.8%HM containing 844,000t of HM at 10.7% zircon, 7.0% rutile and 55.8% ilmenite. The Measured Resource at 2.5% HM cut-off is similarly reduced to 9.7Mt @ 8.3%HM, containing 810,000t of HM at 10.9% zircon, 7.1% rutile and 55.5% ilmenite.

The majority of the HM results for the Rhea deposit were received during the quarter, with laboratory analyses substantially confirming the visual estimates. Assessment of the significance of these results is underway and resource estimation will commence in the June quarter. Visual estimates of mineralogy conducted by an established mineralogical laboratory suggest that the mineral assemblages will be similar to Atlas. Results of QEMSCAN analyses to confirm these estimates are expected during the June quarter.
Magnetic mapping of the newly acquired Munbinia tenement (E70/3997), which covers the southern strike extension of the Atlas deposit has identified a potential 3.5km extension to the Atlas deposit. Image views this as a significant outcome as the potential extension lies in the direction of increasing grade and increased zircon content.
Gingin (Image 100%) and Chandala (Image 60% earning up to 80%)
Resource definition drilling on the Gingin South deposit and first pass drilling on the Chandala tenement was completed during the quarter with a total of 333 holes drilled for 10,114m from which 5,380 samples were selected for laboratory processing. The locations of the drill hole collars are shown in Figure 2. The samples are awaiting analysis at the laboratory and a release will be made once the results have been received and assessed. However, based on visual estimates, the mineralisation in the Gingin South deposit has been confirmed by the infill drilling. The Chandala North drilling has also identified a 2.4km-long mineralised zone and the Target 3 zone has been shown to contain mineralisation in the southernmost line. Over the next quarter Image will progress its assessment of the Gingin and Chandala drilling as drilling results become available, with the aim of estimating a Measured Resource for Gingin South and designing resource drilling for Chandala North.

Iluka Tenement Acquisition (Image 100%)
During the quarter Image finalised an agreement with Iluka Resources (ASX:ILU) to acquire a 100% interest in four granted Mining Leases, shown in Figure 3. Three of these tenements are surrounded by exploration licences comprising Image’s 100%-owned Gingin project, with the fourth adjacent to Image’s Cataby West and Quinns Hill projects.
This acquisition gives Image control of a 65km strike length of the Gingin Scarp. Image has recognised the Gingin Scarp as a high grade/high priority target area based on its drilling at Gingin South; the presence of the high grade 2.5km-long Gingin Mine owned by Iluka; and on detailed ground magnetic surveys carried out over the last two years by Image.
The Iluka Mining Lease resources have been analysed as part of a due diligence process and Table 3 summarises Image’s estimates of the resources at a 2.5%HM cut-off. The fact that the mining leases are granted is considered significant as it will facilitate the fast track of these resources through the permitting process to development, subject to the completion of appropriate agreements with landowners.

This acquisition significantly increases Image’s Dry Mining resource inventory from 1.8Mt of HM to 2.8Mt, an increase of 55% and increases the total Dry Mining + Dredge Mining resource to 7.53 Mt of HM. The elevated zircon content of the Boonanarring resource has been shown by ground magnetics to have the potential to extend at least a further 7.7km to the north on existing Image tenure. This anomaly remains open to the north and will be subjected to ground magnetic surveys. The Gingin South Mining Lease lies directly to the north of Image’s Gingin South deposit (see Figure 2), which extends into the Mining Lease.
Bidaminna (Image 100%)
Late in the quarter, Image began drilling at its Bidaminna project and has completed a total of 6 lines of drilling for 57 holes and 3,035 metres (Figure 4). Two lines were drilled on the northern end of the Bidaminna deposit that was identified by previous explorers in 1990. Image has included the Bidaminna deposit in its resource inventory as an Inferred Resource of 44.6M tonnes at 3.0%HM, containing 1.4M tonnes of HM at a 1%HM cut-off.
The current program was designed principally to test new magnetic targets to the north and east of the Bidaminna deposit. However, two lines were drilled into the northern extent of the known deposit and one hole in the southernmost line (BN018) was found to contain a 30mthick mineralised zone from 27m depth which averaged 7.7%HM using a 1%HM cut-off and includes a 3m intersection averaging 34.7%HM. This grade is significantly higher than reported in adjacent historical drill holes and was confirmed visually by a twinned hole and holes drilled 20m either side across strike. Laboratory processing results for all holes on this line are awaited with interest and will enable Image to put this unexpected high grade intersection in context. However, this intersection has encouraged Image to re-assess the prospectivity of the Bidaminna deposit and more drilling will be scheduled to follow up the potential for a high-grade core to the deposit.

Drilling at the Serpentine Lakes project was delayed by unseasonal wet weather preventing access until the end of March. A Work Area Clearance was conducted by the Traditional Owners and drilling has been rescheduled for June 2011.
COMMODITY PRICE INCREASES
Recent market research released by Goldman-Sachs and industry consultants TZMI has predicted greater increases in zircon and sulphate ilmenite prices than those forecast in Image’s December Quarterly Report, leading Image to revise its product pricing. In the short term TZMI is reportedly predicting zircon prices to reach US$2,000/t by the end of calendar 2011 and to maintain this level to at least 2015. Table 3 shows the product pricing that Image believes is now justified based on this new data.
| Table 3 Forecast Product Pricing 2009– 2014 (US$/t) |

| Rutile | 600 | 820 | >950 |
| Chloride Ilmenite | 110 | 180 | 190 |
| Sulphate Ilmenite | 110 | 180 | 200 |
The predicted increased sulphate ilmenite pricing is significant in the context of Image’s Atlas deposit, where approximately 35% of the ilmenite is likely to be sold to this market. It is also significant for other Image deposits such as Bidaminna which is primarily a sulphate ilmenite deposit.
