NORTH PERTH BASIN
Gingin (Image 100%)
Image identified high grade HM mineralisation immediately south of the Gingin South HM deposit in 2010 and subsequently infilled it to a 100m x 20m drill spacing in early 2011. During the quarter an interim resource estimate was estimated based on a 200m x 20m drill spacing. This interim estimate of Indicated and Inferred Resources for the Gingin South extension totals 5.2Mt @ 6.6% HM, containing 348,000t of HM at a 2.5% HM cut-off. Table 1 summarises the resource status and Table 2 shows the corresponding mineral content.

This new resource is situated immediately south of and contiguous with the HM deposit within mining lease M70/448 acquired from Iluka Resources Limited in March 2011, as shown in Figure 1. The new extension has increased the total deposit length to 5.5 km, with widths varying between 40m and 250m and averaging 120m. The resource was released to the market on 21 July with a detailed description of criteria and parameters.
Using drilling and mineralogical data supplied by Iluka on mining lease M70/448, Image estimated a total Measured and Indicated resource at a 2.5% HM cut-off of 2.8Mt at 5.1% HM, containing 144,000t of HM (refer IMA ASX Release 9 March 2011). Together with the southern extension, the overall Gingin South resource has increased to 8.08Mt @ 6.1% HM, segregated into Measured, Indicated and Inferred categories, as shown in Table 3.

Chandala (Image 80%)
During the quarter Image met the expenditure level required to obtain a further 20% interest in the Chandala Project tenement E70/2742 and has had this recognised by its JV partner, bringing total Image interest in this tenement to 80%. Negotiations are in train with the JV Partner, Derby Mines Pty Ltd, to formalise a contributing JV or purchase the remaining 20%.
Assay results received during the quarter identified a significant strand intersection on the Chandala North target area situated 2.5km south and along strike from the Gingin South resource (Figure 2). These results confirm field estimates of a high grade deposit with intercepts up to 15m @ 11.1% HM from surface and 4m @ 24.0% HM from 30m (2.5% cut-off). Significant intercepts are summarised in Table 4 and drill hole locations shown on Figure 2. A drill section is shown in Figure 3, illustrating the mineralisation outlined to date. Two strand levels have been identified in this section, an upper strand at 74m RL, which contains high grades and outcrops at the surface and a westerly dipping strand at 65m RL, also containing a >10% HM core. These strands are present in drilling to the north and south of this section, giving a total inferred strike length of 2.3km and leaving the mineralisation open to both the north and south. Image is planning to infill the Chandala North mineralisation to 100m x 20m drill spacing to allow estimation of Measured resources as part of its 4[th] quarter drilling program.

All analytical results were received from the Rhea resource drilling described in previous releases. The results are encouraging and show the potential for the estimation of resources on two strand lines, the Rhea strand and the Middle strand. Better intersections are shown in Table 5, including 5m at 10.8% HM from 5m in drill hole RH272 and 2m at 34.8% HM from 6m in RH319. Figure 4 shows the location of the drilling.

The Middle Strand main mineralised zone sits at about 50m RL with low grade (2-4% HM) sheet mineralisation 4-6m below it on a clay basement in a similar stratigraphic position to the central mineralisation at Rhea. The main mineralised zone at Middle Strand is 2-6m thick, 20m to 40m wide, continuous over 1100m of strike with between 1m and 6m of cover. HM grades are higher than Rhea with a continuous core greater than 10% HM throughout. The Middle Strand high grade core will be attractive as a potential satellite orebody to Atlas, Hyperion Helene and Rhea.

The Rhea deposit consists of a narrow upper mineralised zone, 2-4m thick with HM grades up to 11.2% HM and a central zone, 2-10m thick with grades up to 10% HM, but generally between 2- 8% HM. These two zones are separated by between 2m and 4m of barren sand, with the central zone overlying a clay basement of interpreted Mesozoic sediments. The central mineralisation is quite extensive and stretches across the entire drill section overlying a channel of 4-20% slimes cut into the basement clays. This channel contains low levels of HM, but is not as significantly mineralised as the Calypso channel to the north-east.
The water table at Rhea is quite close to the surface, generally between 7m and 10m depth and this, combined with low slimes and moderate HM grades, may make it suitable for a dredging operation. In the meantime further increases in titanium feedstock and zircon prices continue to improve the economic outlook for Image’s North Perth Basin project.

Bidaminna North (Image 100%)
Drilling completed on E70/2844 during the quarter totalled 39 holes for 2369 m. Drilling was focused on targets to north of Moore River along strike from the exiting Bidaminna deposit. No further significant intersections were encountered before the program was prematurely curtailed due to the rig having to move on to jobs for other clients.
Scoping Study
During the quarter two senior consultants were appointed to the following roles as part of Image’s drive to commercialise its North Perth Basin mineral sand project:
- Mr Per Scrimshaw of Creative Mined Enterprises was appointed Development Manager . Creative Mined Enterprises provides specialist technical support to the mining and civil engineering sectors. Creative Mined Enterprises’ experience covers a wide range of commodities, including extensive project exposure to many of the major mineral sand deposits in the Perth Basin.
7
- Mr Alan Luscombe of Lassin Services Pty Ltd was appointed Manager Mineral Process Design . Alan has extensive experience working for RGC Mineral Sands in metallurgical and management positions at both of RGC’s previous east coast and west coast operations, including time as Manager West Coast Operations (Capel and Eneabba) and as Group Mining Manager. More recently Alan has worked as General Manager, Coburn Mineral Sand Project for Gunson Resources, where he has been instrumental in determining metallurgical flowsheets and plant layouts as well as managing the Definitive Feasibility Study for this project.
These appointments were made to significantly strengthen Image’s development team and provide further impetus to Image’s quest to add value for shareholders from its North Perth Basin project. The development team have begun by preparing an economic analysis of Image’s current deposits, including defining new capital estimates, operating costs and using the Nagrom testwork on Atlas to determine likely product recoveries.
EUCLA BASIN (Image 100%)
Wet weather has delayed the start of an 8,000m aircore drilling programme designed to test strike extensions of the Cyclone Extended strandlines. A survey team has completed geophysical traverses across the main target areas and identified 22km of potential strandline targets. The regional stratigraphic drilling approach discussed in previous releases has now been more tightly focussed to concentrate on these targets. Figure 5 shows the identified target areas. The aircore drilling programme is now scheduled to commence in late August.
