Molystrong, I suggested a billion $$ over run @ Mt. Milligan back in May, and I was almost taken to task on it here. Anyways, you're on the right track with your thoughts.
One more thing about the Endako mine, they had to let go three top mining managers go in the last 6 months and they're not getting replaced! The message is there...looks like they're not putting much more cash into Endako as they're trying to find ways to cut costs for now! They're looking for a buyer for that mine!
