c77, I agree entirely that as far as CDU's eventual profitability is concerned it is the AUD price of copper that counts. However, after following commodity companies for over two decades, it never ceases to amaze me that the market only looks at the US$ price for valuation purposes.
So don't be surprised as CDU's sp falls with the copper price. After all, CDU have started that its calculations are based on a Cu price of US$2.
