Is the difference between can and will a matter of profitability?

Thank you Drasselt!
Pebble mine is the one.
Found a good update on it.
Thanks for an intelligent response finally.

Pebble Mine is a classic example of how the actual costs of the mine to society will not be known for decades, and how those costs will be shouldered by the public, the nearby landowners, the natives, and hunters\trappers\ fisherman, instead of the miners themselves. The miners will privatize all of the benefits (gold, profits), and will socialize\ externalize all of the costs and damage from their activity. This is nuts. If the gold there is worth real money, then make sure they clean it all up as they go and bond it all ahead of time, so they can't just declare bankruptcy and walk away from the destroyed landscape. To trade away these increasingly rare, pristine areas so a small handful of people can get wealthy is nuts. Foolish. If someone wants to go mine gold, get a license from the state of AK, fly in your machines, and have at it. Those little mom and pop outfits can make some gold money, but they are very limited in their environmental impact, and the people making the money are the actual people digging in the muck with their own hands.
