Poochera Kaolin Project Location
Poochera Kaolin Deposits
Carey’s Well Kaolin DepositPrefeasibility Study has commenced.This study will include all relevant technical, logistical, environmental andlegal aspects of the project but…..Critical components include:• Development of a range of high quality kaolin products• Specification sheets for each product• Worldwide market appraisal• Obtaining Offtake Agreements or Letters of Intent from Client Companies• Upgrading the Resource to Indicated and Measured categories: drillingplanned for Q1 2011It’s all about marketing!

CAREY’S WELL CALCINED <strong>KAOLIN</strong>
In summary, the Carey’s Well Kaolin Deposit:• Is very large (>50 year potential mine life based on the 20 million tonneinferred resource and kaolin production of 100,000 tonnes per annum)• Appears to be very uniform in quality and distribution (based onassessment of historical drilling and bulk sample processing)• Has all the physical and chemical qualities to allow production of highquality hydrous kaolin using conventional processing techniques• Demonstrates all the properties required for very high quality calcinedkaolin feedstock and trials have produced premium quality calcinedkaolin• Is well located with a port at Thevenard within easy trucking distance• Has an excellent waste to ore ratio and could be mined using simpleopen cast mining processes.
