SUMMARY
Based on the positive results of the August 2011 Scoping Study on the mostly 100%owned North Perth Basin Heavy Mineral Project in Western Australia, Image has targeted 2014 for the commencement of production.
The project represents one of the largest undeveloped high-grade HM resources in Australia.
Robust economic returns for the project demonstrated by and within the parameters of the study, indicate a capital payback period of between 18 and 22 months from a 3.6M tonnes per annum sequential, multi-pit operation encompassing six of Image’s defined resources located between Cooljarloo in the north to Gingin in the south.
The study envisages production at an average of approximately 185,000 tonnes of heavy minerals in concentrate per annum for 12 years. Production over the life of the mine is expected to total approximately 1,393,000t of ilmenite (+50% SR grade), 85,000t of rutile, 193,000t of zircon and 93,000t of leucoxene using a conventional Wet Concentrator Plant and Mineral Separation Plant.
Using A$0.90 and A$1.00 to the US dollar exchange rates, the study indicates the project can generate a net project cash flow of between $170 million and $259 million over the 12 year period.
Preliminary non-optimised metallurgical test work performed on the Atlas deposit using conventional heavy mineral separation techniques yielded recoveries to product of 82.7% for ilmenite, 71.9% for rutile, 70.7% for zircon and 43.8% for leucoxene. Similar recoveries have been applied to the remaining deposits where testwork is yet to be carried out. It is anticipated that further test work will significantly improve on the initial Atlas deposit test work recoveries.
According to Image’s managing director, George Sakalidis; “The robust outcomes of the study are an extremely positive sign for the company given the conservative estimates of commodity pricing and metallurgical recoveries.”
“We have now achieved a critical mass for the resource base which, combined with solid grades and projected strong commodity prices, provides Image with the opportunity to become a substantial and highly profitable long term heavy mineral producer.” he said.
“The study results vindicate the Board’s strategy; Image is now well placed to capitalise on the buoyant heavy mineral market for the benefit of shareholders.”
Based on these results, the Board of Image has resolved to commence a Feasibility Study with the aim of achieving production in 2014.

SCOPING STUDY
The Scoping study was carried out by the following consultants to the company:
-
Widenbar & Associates Resource estimation
-
Lassin Services Pty Ltd Process design
-
• Nagrom Pty Ltd Metallurgical testing • Engenium Capital and operating costs • Creative Mined Pty Ltd Mine design and optimisation
The Scoping Study examined a 400 tonnes per hour Wet Concentrator Plant (WCP) with a 30 tonnes per hour Mineral Separation Plant (MSP) scenario for a stand alone operation.
The study process design contains a number of constraints, leaving scope to improve efficiencies and increase value. Increased throughput of 600 tonnes per hour and the option of producing a mixed HM concentrate for sale, with no MSP, will be examined.
All dollar values are Australian dollars unless indicated otherwise. Exchange rates of A$1.00 and A$0.90 to the US dollar were applied during the Scoping Study, resulting in a range of financial outcomes. The A$0.90 case accords with the Bloomberg Consensus 2014 exchange rate forecast by major contributing global banks. Pit optimisations were carried out using the A$1.00 exchange rate pit shells. The A$0.90 exchange rate was applied to the revenue stream using the A$1.00 exchange rate pit shells and costs.
Exchange rate has the most significant effect on financial performance. A 5% variation in exchange rate generates a 25% variation in NPV. By comparison a 5% variation in either operational costs or zircon price produces 15% NPV deviation, whilst the NPV deviation is 8% for the same variation in either development capital expenditure or ilmenite price.
IDENTIFIED MINERAL RESOURCES
The study assessed all of Image’s identified mineral resources as at 22 July 2011 and demonstrates that mining just six of Image’s 100% owned resources, using the Scoping Study parameters, is viable. These resources are summarised below with a more detailed breakdown shown in Appendix 1. All three resource classifications have been included to allow assessment of priorities for further development.

The resource block models for each deposit were regularised and values assigned prior to pit optimisation. The output of the pit optimisation was used to rank each deposit by a series of key performance indicators, including annual value and strip ratio. The ranking was used to sequence the mining of the deposits and create a life of mine schedule. The output from the schedule was analysed on an annual basis and used to estimate project economics.
Prior to scheduling, the optimised resources were excluded if they had a mine life of less than one year or a total value of less than the cost of relocating the WCP to site. Individual pits were excluded if they had an area of less than 1ha. These parameters resulted in the exclusion of the Boonanarring, Cooljarloo and Bidaminna resources from the mining schedule.
PROJECT ECONOMICS
Based on the results of the study for a 400tph concentrator over 12 years the project economics are summarised as follows:

|---|---|---|
| Exchange Rate (A$:US$) | 1.00 | 0.90 |
| Commodity prices: ilmenite rutile zircon leucoxene |
US$ 200 US$ 1350 US$ 2240 US$ 500 |
|
| Mine Life | 12 years | |
| NPV @ 10% discount | $58.8M | $97.6M |
| AverageIRR(Internal Rate of Return) | 32.1% | 42.9% |

Annual operating costs have been estimated at $44.7M for the project. Mining contractors have been allowed for in order to initially reduce capital costs and increase flexibility. This strategy will be confirmed in later studies. Processing costs have been estimated using electric power from the grid with provision for the capital cost of power lines.
Estimated operating costs are as follows:

| Total Off Site Operating Costs | 9.5M/yr |
| TOTAL OPERATING COSTS | 44.7M/yr |
LAND STATUS
Mining tenure to the six resources is a mix of granted mining leases and exploration licences. Mining leases will now be applied for over those resources not already so covered.
The six resources are situated on a mix of Freehold Land and Vacant Crown Land. Whether native title affects any of the Vacant Crown Land is being investigated. Ethnographic studies to date have not identified any significant heritage sites, although surveys remain to be completed over a limited number of areas. Environmental studies have not indicated endangered priority species plants within the proposed mining areas however surveys remain to be completed in some areas.
MINING METHOD
The study utilised conventional dry mining techniques typical of current mineral sand mining practice in the region, entailing overburden removal by hydraulic excavator and ore mining by scrapers and/or excavators. This is a low risk and highly flexible mining method that can adapt to variable in-pit conditions.
FEASIBILITY STUDY
Based on the results of the Scoping Study, the Image Board has decided to proceed immediately with a Feasibility Study with the aim of achieving production in 2014.
5
The Feasibility Study work schedule includes the following:
-
Infill drilling
-
Resource upgrades
-
Recruitment of key personnel
-
Metallurgical testwork
-
Geotechnical drilling/testwork
-
Ethnographic and environmental studies
-
Detailed engineering design
-
Detailed capital and operating cost estimates
The infill drilling during the Feasibility Study will target areas classified as Inferred Resources to upgrade them to Indicated or Measured Resources. This drilling and the high likelihood of identifying extensions to resources have the potential to positively impact project economics.
EXPLORATION UPSIDE
Image remains committed to a focussed exploration programme to increase the project resource base.
Significantly :
-
grant of the tenement covering an interpreted 3.5km extension of the highgrade Atlas deposit is imminent and drilling of this extension is anticipated to start in the next quarter;
-
the established zircon-rich Boonanarring resource is interpreted to extend for a further 7.7km. Drilling of this extension is anticipated to significantly expand and upgrade this resource and allow for its inclusion in the mining schedule;
-
at least another 100km of magnetic targets remain to be drill tested on a number of prospective shoreline positions, particularly in the Gingin area. This exploration programme will target shallow high-grade deposits, similar to Atlas, which have the capacity to increase the project life and/or throughput and to improve project economics.
