i'm with @Midnight26 - when your main ore source is under-performing then you read about a 'structural re-interpretation' there is trouble ahead. there are other companies i follow that are in a similar situation, so these can be managed and turned around, but it requires a good hard look at the operations and costs, and nursing the baby until it is strong enough to walk on its own two feet.
i think after the eastern goldfields saga punters are a bit gun-shy on this one.
