Ann: Successful High-Grade Ore Sorter trial , page-33

Hi Swithchmullet,

Rome wasn't built in a day.

The purpose built main native copper processing circuit, which forms part of the Rocklands Process Plant,is curently under construction and due for completion late 2014.

Native copper recovery via "scalping" through the crushing circuit is being employed as an interim measure to produce copper poduct and early revenue, whilst the process plant is being completed.

Concentrate product produced at the ore sorter is loaded into half-sized containers for shipping. A 20 tonne load of copper concentrate from the ore-sorter fills one of these containers to a height of just ~250mm.

Recent crushing of oxide native-copper (head-grade estimate 2-3% Cu) produced a ~95% coarse native concentrate product(visual estimate).

The current trial ore-sorter is capable of procssing 50 tonnes per hour and it is anticipated will shortly process high grade native copper ore with estimmated grades of ~5 - ~8% Cu.

Also, large coarse native copper metal masses are being "scalped" via screens in the crushing circuit. Native copper recovery via "scalping" over screens through the crushing circuit is an interim measure to produce copper product and early revenue.

The native copper zone at Rocklands is fully accessible via open-pit mining, offering front-end benefits of high grade ore early in the revenue cycle.

What the team at CuDeco have done is doggedly continue to invest time, money and significant effort in devising specialised processes and procedure and construction of a crushing and process plant like no other in the country.

Whilst getting Rocklands into production CuDeco Management is value-adding as progress is being made to this end.

It all means bigger dividends for CDU shareholders when Rocklands production commences, and hopefully no kinks in the plant; which should operate efficiently from the out-set, and as a result of the up-sizing.

When you are spending $275m+ you want the best result for CDU shareholders.

Shorters are an anathema.


cheers,

Max
