Preliminary pit layouts
Site features
Cleared pastoral country
Series of 4 flat bottom open pits over 4km strike
Initial study
Estimated average strip ratio 7.2:1 waste:ore
1Mtpa ore throughput over 5 years
Current thinking
Preliminary pit optimization completed
Lower cost mining methods under review
More tonnes likely
Lower strip ratio – meaning lower economic grades
EOI – 12 contractors have responded

Metallurgical test‐work
Free digging ore
Screen and slurry
Minimal comminution for aggregates and lumps
Cyanide leach to recover most silver
Low cyanide and lime consumption
Gravity concentrate for lead and residual silver
Latest cyanidation results confirm previous results
Control Ph to control slurry viscosity
Lower reagent consumption
Significant reduction in water requiements

$21 capital cost – based on new 1Mtpa processing plant
With infrastructure requirements and working capital, total investment may be in the order of $25 to $30M
Funding options
• Equity, debt or hybrid security• Silver or lead financing

CBH to dilute
15
CBH has advised it will not contribute to additional expenditure or fund its share of feasibility study costs
CBH interest will be diluted/Cobar interest increased
Assuming feasibility study is completed on budget, CBH interest reverts to 2% royalty

SummaryWonawinta feasibility study in progress
First phase of RC drilling completed
50Moz indicated and inferred silver resource ‐more ounces, higher grade, higher quality
Second phase RC drilling starts today
Met test‐work confirming earlier results
Complete feasibility study by mid 2010
Production potential by 2011
Huge exploration upside
