I know all the work that's being done to make that happen, but is there anything that actually has happened that we could use as a model? Off the top of my head, you could look at Detour Gold, the De Beers mine, the Victor Diamond Mine, and the Musselwhite Mine.
Sans que j'y aie trop réfléchi, je pourrais citer en exemple la mine d'or Detour, la mine de De Beers, la mine de diamants Victor et la mine Musselwhite.
