Thank you for the feedback from BDR on total costs.
Based on total cost of $700, and assuming 200KOz production, a pessimistic average gold price of US$1500, and tax + royalty of 18%, the NPAT for CY2013 should be around $131M which is a P/E of only 4.4 at current prices.
That's a bargain in my mind. Profits will of course be much higher on a higher gold price, which is highly likely IMO.
