Another option is to consider is whether anything can be made of Promontorio. Do we know enough about the superficial epithermal systems overlying the porphyry? Could we ignore the copper and try to track down some gold/silver and could we reasonably do that without spending the bulk of our cash warchest? To their credit AZS have shown themselves to be capable of doing a lot of exploration for the money.
I agree we need to play the waiting game with Teck and endure that frustration.
