Foreign ExchangeSomething I would like to mention in regards to the pre-feasability study: foreign exchange.
The biggest hurdle to getting this mine up and running is the initial capital expenditure, which the recent presentation indicates would be $607m CAD, or $461m USD.
Canadian dollar has been climbing recently, and that could bode well for the actual expense figure.
...It could also mean nothing if it is actually just the US dollar falling instead of the CAD rising (which is what I think is more likely).
Either way, my take is that the current trend is either good or neutral. Not bad.
