If Caribou is the main food source for local people and critical for their survival then why not fence the mine off to protect them from it and start a caribou farm elseware and teach them how to manage it. If it is all about the tradition of the hunt,they would still be able to participate without the pressure of success. As far as the fishing concern I think they have alot of lakes that could be stocked and managed to more than compensate for any loss at Kennady lk. I believe this is allready in the plan.
